Description

Image recording system and control method of heterogeneous recording structure

The present invention relates to an image recording system, in particular to an image recording system and a heterogeneous recording framework, which can control all the camera devices under the heterogeneous recording framework to start shooting accordingly.

In recent years, as the public's awareness of safety has increased, street surveillance cameras and related technologies have played an important role in improving safety, traffic management, and emergency response. Cities and local governments usually install surveillance cameras in public places to improve public safety, monitor and prevent criminal behavior, and assist law enforcement agencies in responding to emergencies. In addition to installing surveillance cameras at fixed locations on the streets and on mobile vehicles, police officers can also assist in police work by wearing wearable cameras when on duty. The media data recorded by surveillance cameras or cameras can also be used to provide evidence and clarify responsibilities in the future.

In view of this, the present invention provides an image recording system and a control method of a heterogeneous recording structure, so that when a specified event occurs in any device in the heterogeneous recording structure, all the camera devices in the heterogeneous recording structure can simultaneously take pictures, so as to record the changes of the surrounding environment with images.

In one embodiment, the image recording system includes a host and a plurality of camera devices, and the host is connected to each camera device. The host includes at least one data connection port, a first wireless communication module, a wired network module and a processing module. At least one data connection port is connected to the control circuit of at least one peripheral non-camera device. The processing module is connected to at least one data connection port, the first wireless communication module and the wired network module to receive current event information from at least one data connection port, the first wireless communication module and one of the wired network modules. The plurality of camera devices are connected to the host, and the plurality of camera devices include at least one first camera device and at least one second camera device. At least one first camera is wirelessly connected to the first wireless communication module, and each first camera is used to photograph the surrounding environment and generate corresponding current event information indicating that photography has started. At least one second camera is wiredly connected to the wired network module, and each second camera is used to photograph the surrounding environment and generate corresponding current event information indicating that photography has started. The current event information is generated by at least one non-camera device, the first camera, and the second camera. The processing module generates a trigger signal based on the current event information, and the trigger signal triggers multiple cameras other than the camera that generates the current event information to start photography.

In one embodiment, the control method of the heterogeneous recording architecture includes: connecting to a control circuit of at least one peripheral non-camera device via at least one data connection port; connecting to at least one first camera device among a plurality of camera devices via a wireless communication module; connecting to at least one second camera device among a plurality of camera devices via at least one connection line; and connecting to the control circuit of at least one peripheral non-camera device via at least one data connection port, wireless communication module, and wireless communication module. The module and at least one of the connection lines receive current event information, wherein the current event information indicates that the camera device starts to take pictures of the surrounding environment or indicates that the non-camera device performs a specified operation; a trigger signal is generated according to the current event information; the trigger signal is sent to the camera device other than the camera device that generates the current event information among the plurality of camera devices; and the camera starts to take pictures in response to the trigger signal.

Refer to Figures 1 to 3. The image recording system includes a host 10 and multiple camera devices 30. Here, the host 10 is connected to each camera device 30 via a network. The multiple camera devices 30 have two types of camera devices (hereinafter referred to as the first camera device 32 and the second camera device 34) connected to the host 10 in different communication methods. Although Figures 1 and 2 only depict a single first camera device 32 and a single second camera device 34, this number is not limited. In fact, the image recording system can also be set with multiple first camera devices 32 and/or multiple second camera devices 34 according to actual needs.

The host 10 includes at least one data port 12 , a wireless communication module (hereinafter referred to as the first wireless communication module 14 ), a wired network module 16 and a processing module 18 .

The host 10 is connected to each first camera device 32 and the second camera device 34. Here, the processing module 18 is wirelessly connected to each first camera device 32 via the first wireless communication module 14, and the processing module 18 is also wiredly connected to each second camera device 34 via the wired network module 16. In other words, a communication channel is established between the host 10 and the first camera device 32 on the wireless communication network. The host 10 and the first camera device 32 are connected to each other by a connection line 50, and a communication channel is established between the two on the wired communication network.

In addition, there is at least one non-camera device 20 around the host 10, so in addition to connecting each camera device 30, the host 10 is also connected to the control circuit 22 of at least one non-camera device 20. Here, the processing module 18 is connected to the control circuit 22 via the data port 12. In other words, the host 10 and the control circuit 22 of the non-camera device 20 are connected to each other by a data line, and the data line provides a communication channel between the two. For example, the host 10 can be set on the vehicle 2. Here, the control circuit 22 can be implemented by the vehicle electronic motherboard of the vehicle 2, the electronic device installed on the vehicle 2 (for example: intercom, buzzer, warning light or safe, etc.). The vehicle electronic motherboard is generally used to control various mechanical assemblies of the vehicle 2 (for example: window lifting assembly, airbag assembly, seat belt assembly, steering assembly, etc.), and the electronic device installed on the vehicle 2 may have a control circuit 22 independent of the vehicle 2. The data connection port 12 of the host 10 is connected to the data connection port (not shown) on the vehicle 2 by a connection line (not shown) to transmit data with the control circuit 22.

In one example, one control circuit 22 can control a single non-camera device 20. In another example, one control circuit 22 can also control multiple non-camera devices 20 simultaneously. In some embodiments, the host 10 can have a single data port 12. In other embodiments, the host 10 can also have multiple data ports 12 to connect multiple control circuits 22.

Here, the host 10, the plurality of camera devices 30 and the non-camera device 20 can constitute a heterogeneous recording architecture that cooperates with each other. The following takes a non-camera device 20, a first camera device 32 and a second camera device 34 as an example, but this number is not limited to the present invention.

Refer to FIG4. In some embodiments, the first camera device 32 includes a camera module 320, a positioning module (hereinafter referred to as the first positioning module 322), a communication module (hereinafter referred to as the second wireless communication module 324) and a control module 326. The control module 326 is connected to the camera module 320, the first positioning module 322 and the second wireless communication module 324. The second wireless communication module 324 is wirelessly connected to the first wireless communication module 14 of the host 10 to establish communication between the first camera device 32 and the host 10.

The camera module 320 is used to perform the aforementioned photography of the surrounding environment to generate images that record the surrounding environment. In some embodiments, the camera module 320 can be in an activated state at any time, and the camera module is turned on after being triggered. In other embodiments, the camera module 320 can also be preset to a closed state, and only start and start photography when triggered. The control module 326 is used to control the operation of each component (i.e., the camera module 320, the first positioning module 322, and the second wireless communication module 324). The first positioning module 32 locates the location of the first camera device 32 to generate geographic data indicating the location of the first camera device 32 (hereinafter referred to as the first geographic data G1). The first geographic data G1 may be, for example, longitude and latitude coordinates.

In some embodiments, the first camera device 32 may further include a storage module 328. The storage module 328 is connected to the control module 326. When the first camera device 32 is taking pictures, the control module 326 can store the image generated by the camera module 320 taking pictures of the surrounding environment in the storage module 328. In addition, the control module 326 can also store the first geographic data G1 independently or combine the first geographic data G1 to generate the image obtained by the current shooting and store it in the storage module 328.

Refer to Figure 5. In some embodiments, the second camera device 34 includes a wired network module 340, a control module 342, and a camera module 344. The second camera device 34 is connected to the host 10 via the wired network module 340, and the control module 342 controls the operation of the camera module 344. In addition, the second camera device 34 can be divided into two types, namely, a second camera device 34a with a storage module 348 and a second camera device 34b without a storage module 348. The two types of second camera devices 34a, 34b can exist at the same time or only one of them can exist. When they exist at the same time, the two types of second camera devices 34a, 34b can be connected to each other via an intranet. The storage module 348 is used to store the images captured by the camera module 344. When the second camera device 34b cannot transmit the captured images to an external memory for storage via the wired network module 340, the second camera device 34b can transmit the captured images to the storage module 348 of the second camera device 34a for storage via the connection with the second camera device 34a.

For example, the dash cam of the vehicle 2 may have a front lens for capturing images in front of the vehicle 2 and a rear lens for capturing images behind the vehicle 2, wherein only the front lens has a storage module 348, and the images captured by the rear lens may be transmitted to the storage module 348 of the front lens for storage.

Refer to Figures 1, 2, and 6. When the image recording system is running, the host 10 is connected to the control circuit 22 of the non-camera device 20 and each camera device 30 via the data port 12, the first wireless communication module 14, and the wired network module 16, and detects whether there is current event information I1 from the control circuit 22 and/or any camera device 30 (step S100). When any of the non-camera device 20, the first camera device 32, and the second camera device 34 (hereinafter referred to as the event device) has a designated event, the event device will generate current event information I1 representing the occurrence of the designated event, and send the generated current event information I1 to the host 10 (for example, the event device shown in Figure 1 is the non-camera device 20). The processing module 18 receives the current event information I1 from the connection interface corresponding to the event device (i.e., the data connection port 12, the first wireless communication module 14, or the wired network module 16) (step S120), and generates a trigger signal T1 according to the received current event information I1 (step S140). Then, the processing module 18 sends the generated trigger signal T1 to the camera device 30 outside the event device (step S160). The camera device 30 starts shooting in response to the trigger signal T1 (step S180).

For example, assume that the non-camera device 20 has a designated operation, and the occurrence of a designated event is the execution of the designated operation. Refer to Figure 7. When the non-camera device 20 executes the designated operation, the control circuit 22 of the non-camera device 20 generates current event information I1 indicating that the designated operation has been executed, and sends it to the host 10 via the connection line 50. The processing module 18 of the host 10 receives the current event information I1 via the data port 12 and generates a trigger signal T1 accordingly. Then, the processing module 18 transmits the generated trigger signal T1 to the first camera device 32 and the second camera device 34 via the first wireless communication module 14 and the wired network module 16 respectively. After receiving the trigger signal T1, the first camera device 32 and the second camera device 34 start taking pictures in response to the trigger signal T1, so as to record images of changes in the surrounding environment.

In another example, assume that the designated event of the first camera device 32 is to take a picture, and the occurrence of the designated event is the start of taking a picture. Referring to FIG. 8 , when the designated event occurs in the first camera device 32a (i.e., the camera module 320 starts taking a picture), the control module 326 generates current event information I2 representing the occurrence of the designated event. After receiving the trigger signal T2, the second camera device 34 responds to the trigger signal T2 and starts taking a picture. The control module 326 sends the current event information I2 to the host 10 via the second wireless communication module 324. The processing module 18 of the host 10 receives the current event information I2 via the first wireless communication module 14 and generates a trigger signal T2 accordingly. Then, the processing module 18 transmits the trigger signal T2 to the second camera device 34 via the wired network module 16 .

For example, when the image recording system has other camera devices 30 (such as the second camera device 34) in addition to the first camera device 32a, after the first camera device 32a starts taking pictures, the second camera device 34 will also receive the trigger signal T2 and be triggered accordingly to start taking pictures. If the image recording system also has another first camera 32b (i.e., multiple first camera 32a, 32b and at least one second camera 34), after the first camera 32a starts to take pictures, the processing module 18 not only transmits the trigger signal T2 to each second camera 34 via the wired network module 16, but also transmits the trigger signal T2 to the first camera 32b via the first wireless communication module 14. After receiving the trigger signal T2, the first camera 32b and each second camera 34 respond to the trigger signal T2 and start taking pictures.

Furthermore, the designated event of the second camera device 34 may also be photography, and the occurrence of the designated event means that the second camera device 34 starts to take pictures. Refer to Figures 2, 5 and 9. For example, the camera device 30 has two first cameras 32a, 32b and two second cameras 34a, 34b. When the camera module 344 of the second camera device 34a starts to take pictures, the control module 342 generates current event information I3 indicating that the photography is in progress, and sends it to the host 10 via the wired network module 340. The processing module 18 of the host 10 receives the current event information I3 via the wired network module 16 and generates a trigger signal T3 accordingly. Here, the event device is the second camera device 34a, and the processing module 18 transmits the generated trigger signal T3 to the camera device 30 other than the event device. Therefore, the processing module 18 transmits the trigger signal T3 to the first camera devices 32a and 32b respectively through the first wireless communication module 14, and transmits the trigger signal T3 to the second camera device 34b through the wired network module 16. After receiving the trigger signal T3, the first camera devices 32a, 32b and the second camera device 34b respond to the trigger signal T3 and start shooting.

Refer to FIG. 10. In some embodiments, the image recording system further includes a drone 36, which includes a flight body 369, a second positioning module 362, a third wireless communication module 364, a control module 366, and a camera module 360. The camera module 360, the second positioning module 362, the third wireless communication module 364, and the control module 366 are all located on the flight body 369, and the camera module 360, the second positioning module 362, the third wireless communication module 364, and the control module 366 are connected. Furthermore, the drone 36 is wirelessly connected to the first wireless communication module 14 of the host 10 through the third wireless communication module 364, thereby establishing communication between the drone 36 and the host 10. The second positioning module 362 can generate geographic data of the location of the drone 36 (hereinafter referred to as the second geographic data) when performing positioning.

Referring to FIG. 4, FIG. 8 and FIG. 10, when a designated event occurs in the first camera 32a (i.e., the camera module 320 starts to take pictures), the control module 366 generates current event information I2 indicating the execution of the event, and at the same time, the first positioning module 322 of the first camera 32a locates the location of the first camera 32a to generate the first geographic data G1. The control module 326 of the first camera 32a sends the current event information I2 and the first geographic data G1 to the host 10 via the second wireless communication module 324. The processing module 18 of the host 10 receives the current event information I2 and the first geographic data G1 via the first wireless communication module 14, and generates a trigger signal T2 according to the current event information I2. Then, the processing module 18 transmits the trigger signal T2 to the second camera device 34 via the wired network module 16 and to the drone 36 via the first wireless communication module 14 .

The operation of the second camera device 34 after receiving the trigger signal T2 is as described above and will not be repeated here. After receiving the trigger signal T2 and the first geographic data G1, the drone 36 turns on the second positioning module 362 to position itself, activates the flying body 369 based on the second geographic data of the drone 36 obtained by positioning and the received first geographic data G1, and controls the flying body 369 to go to the target position represented by the first geographic data G1. After the flying body 369 arrives at the target position, the control module 366 controls the camera module 360 on the drone 36 to start taking pictures.

In some embodiments, the drone 36 may further include a storage module 368. The storage module 368 is connected to the control module 366. When the camera module 360 is taking pictures, the control module 366 can store the images of the surrounding environment captured by the camera module 360 in the storage module 368. In addition, the storage module 328 can also provide the calculation formulas and parameters required for the flight body 369 to be executed by the control module 366 and control the operation of the flight body 369.

Refer to Figure 2 and Figure 11. In some embodiments, upon receiving each current event information I1, I2, I3, the host 10 may first confirm whether each current event information I1, I2, I3 is a repeated event, and then select to generate or not generate the trigger signal T1, T2, T3 according to the confirmation result.

In one exemplary embodiment, after receiving the current event information I1, the processing module 18 determines whether to generate a trigger signal T1 by comparing the current event information I1 with the existing event information. The host 10 may include a storage module 19, and the storage module 19 is coupled to the processing module 18. The storage module 19 has at least one existing event information. In some embodiments, when the processing module 18 generates the trigger signal T1, it will also store the current event information I1 in the storage module 19. The current event information I1 stored in the storage module 19 is used as the existing event information, thereby indicating that the trigger signal T1 is generated based on the current event information I1 to trigger other camera devices 30 to start shooting.

After receiving the current event information I1, the processing module 18 compares the current event information I1 with each existing event information in the storage module 19 (step S142), determines whether any existing event information matches the current event information I1 (step S143), and generates a trigger signal T1 when the current event information I1 does not match each existing event information (step S144), and then stores the current event information I1 in the storage module 19 as the existing event information (step S146). If the current event information I1 matches any existing event information in the storage module 19, the processing module 18 discards the current event information I1 and does not generate the trigger signal T1 (step S148).

In some embodiments, the event identifier of the event information may be used to determine whether the existing event information matches the current event information I1. As described above, when a designated event occurs in the event device, the event device generates current event information I1, I2, I3 representing the occurrence of the designated event, and sends the generated current event information I1, I2, I3 to the host 10. The designated event occurring in the non-camera device 20 may be the non-camera device 20 performing a designated operation, such as the engine of the vehicle 2 starting, the buzzer ringing, the warning light lighting up, or the safe opening, and the designated event occurring in the camera device 30 may be the start of photography. The current event information I1, I2, I3 representing the occurrence of different designated events may each have a corresponding event identifier. For example, the current event information I1, I2, I3 representing the engine starting, the buzzer ringing, and the camera 30 taking a picture may each correspond to a different event identifier. When the processing module 18 stores the current event information I1, I2, I3 as existing event information, the event identifier corresponding to the current event information I1, I2, I3 is stored in the storage module 19.

After receiving the current event information I1, the processing module 18 can first confirm whether the current event information I1 has a corresponding event identifier. If so, the processing module 18 extracts the event identifier for subsequent comparison. If not, the processing module 18 first identifies the specified event that has occurred, then gives the current event information I1 an identifier, and uses this event identifier for subsequent comparison.

Then, when the processing module 18 compares the event identifier corresponding to the current event information I1 with each event identifier in the storage module 19, if the event identifier corresponding to the current event information I1 does not match each event identifier in the storage module 19, the processing module 18 generates a trigger signal T1. If the event identifier corresponding to the current event information I1 matches any event identifier in the storage module 19, the processing module 18 discards the current event information I1 and does not generate a trigger signal T1.

Refer to Figures 2 and 12. In other embodiments, the processing module 18 determines whether to generate trigger signals T1, T2, T3 after receiving the current event information I1, I2, I3 based on the operating status of the plurality of camera devices 30. The storage module 19 in the host 10 can be used to store a device status file, which records the operating status of the plurality of camera devices 30. The operating status can be mainly divided into "not taking pictures" and "taking pictures".

After receiving the current event information I1 from the control circuit 22, the first camera 32, and the second camera 34, the processing module 18 extracts and stores the device status file of the first camera 32 and the second camera 34 (step S152). Then, the operating status of each camera 30 recorded in the device status file is confirmed (step S154), and a trigger signal T1 is generated according to the operating status of the camera 30 that generates the current event information I1 (step S156). If the operating status of the camera 30 that generates the current event information I1 is "not taking pictures", the trigger signal T1 is generated. When the camera 30 starts photographing, generates a trigger signal T1 and sends it to other camera devices 30 (step S157). Other camera devices 30 respond to the trigger signal T1 and start photographing. At the same time, the operating status of each camera device 30 in the device status file is updated to "photography in progress" (step S158).

In some embodiments, the processing module 18 confirms the device status file based on the current event information I1. When the operating status of the camera 30 that generates the current event information I1 recorded in the device status file is "photography in progress", the processing module 18 responds to this operating status without generating the trigger signal T1 (step S159).

In some embodiments, the processing module 18 can determine whether to generate a trigger signal T1 based on the operating status of multiple imaging devices 30. This is because when the operating status of the imaging device 30 that generates the current event information I1 is "not photographing", it means that no trigger signal T1 has been transmitted to the imaging device 30 before, and it can be inferred that other imaging devices 30 are not in the operating status of "photography in progress". If the operating status of the camera device 30 that generates the current event information I1 is "photography in progress", it means that it has already responded to the trigger signal T1 and started photographing. The trigger signal T1 is generated by the processing module 18 based on the current event information I1 of other camera devices 30. It can be inferred that other camera devices 30 are also in the "photography in progress" state, and there is no need to resend the trigger signal T1 to make the camera device 30 that is already in the "photography in progress" restart photographing.

It should be noted that, although the above steps are described in sequence, this sequence is not a limitation of the present invention, and a person skilled in the relevant art should understand that under reasonable circumstances, the execution sequence of some steps can be performed simultaneously or in sequence.

In some embodiments, the host 10 may be a host 10 installed in a police car, a police station, a security unit, or any law enforcement-related unit.

In some embodiments, the data connection port 12 may be various ports for transmitting data, and one data connection port 12 may be connected to the control circuit 22 of one peripheral non-camera device 20 or may be connected to the control circuits 22 of multiple peripheral non-camera devices 20 at the same time.

In some embodiments, the wired network module 16 may be Ethernet, phone line, coaxial cable, fiber optic, etc.

In some embodiments, the wireless communication module may be a short-range communication unit supporting short-range communication technology, and is configured to send packets to a device with a short-range communication unit located in a relatively short range of the first camera 32 and the drone 36 and/or receive packets from a device with a short-range communication unit located in a relatively short range of the first camera 32 and the host 10. The short-range communication unit may be, for example, a transmitter, receiver or transceiver using technologies such as wireless local area network technology (WiFi), Bluetooth, wireless radio frequency identification (RFID), Z-Wave, infrared communication technology (IrDA), ultra-wideband (UWB) or ZigBee.

In some embodiments, the host 10 may be further provided with a wireless network module supporting long-distance communication technology, such as supporting 2G communication of GSM900, GSM1800, 2.5G communication using time division multiple access (TDMA), 3G communication using code division multiple access (CDMA), 4G communication using high-speed packet access (HSPA), or 5G communication using extremely high frequency (EHF) electromagnetic waves.

In some embodiments, the processing module 18 and any of the control modules 326, 342, 366 may be composed of one or more processing units, wherein each processing unit may be, for example, a microprocessor, a microcontroller, a digital signal processor (DSP), a central processing unit (CPU), a programmable logic controller (PLC), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a finite-state machine (FSM). In some embodiments, the processing unit may be implemented by an integrated circuit (IC), a system-on-a-chip (SoC), or any analog and/or digital device that operates on signals based on operating instructions.

In some embodiments, each camera device 30 and the camera module 360 in the drone 36 may be implemented by an audio and video input device including a camera lens and/or a microphone. The first camera device 32 may be a wearable camera (BWC). The second camera device 34 may be an IP camera (IPcam), an IP camera center or a dash cam.

In some embodiments, the non-camera device 20 and the second camera device 34 may be located on a vehicle 2 such as a motorcycle, a car, a truck, or a bus.

In some embodiments, the first positioning module 322 and the second positioning module 362 can be implemented by a global positioning system (GPS), etc. The processing module 18 can determine whether to send the trigger signal T1 only to some of the camera devices 30 based on the first geographic data generated by the first positioning module 322, rather than to all the camera devices 30 other than those generating the current event information I1.

In some embodiments, the storage module 19 can be implemented by one or more storage elements, such as memory, memory card or register, but this is not limited here.

The flight body 369 of the drone 36 can be composed of a flight mechanism and a driving circuit.

In summary, according to any embodiment, when a designated event occurs in any of the non-camera device 20, the first camera device 32 or the second camera device 34, the camera devices other than the event device can also start taking pictures, so as to record the changes in the surrounding environment with images, thereby being able to record the event more comprehensively when it occurs.
