Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, in one embodiment, a display system 100 for vehicle-mounted blind area images is provided. Referring to fig. 1, the display system for vehicle-mounted blind area images specifically includes:
the video image acquisition module 101 is used for acquiring video images of each blind area of the vehicle through image acquisition equipment installed in the blind areas to obtain blind area video images corresponding to the blind areas, and acquiring a reversing video of the vehicle through the vehicle reversing camera to obtain a reversing video image.
The image acquisition equipment is equipment with image and video acquisition functions, and can be installed in various directions of the vehicle to acquire real-time video images of various blind area views of the vehicle. When a driver drives a vehicle, a plurality of visual field blind areas exist, and if the real-time situation of each visual field blind area cannot be observed in time, accidents can occur. The visual field blind area can at least comprise a vehicle front blind area, a vehicle rear blind area, a left side A column front blind area, a left side rearview mirror blind area, a right side A column front blind area, a right side rearview mirror blind area and the like. The view blind area can be determined according to the requirements of a driver, namely, the image acquisition equipment of the blind area can be correspondingly increased or reduced according to the requirements. If the vehicle is provided with the reversing camera, a rear blind area camera does not need to be additionally installed, and a reversing video image acquired by the reversing camera provided by the vehicle can be directly acquired; if the vehicle is not provided with the reversing camera, the corresponding camera for the blind area behind the vehicle can be installed automatically, and the blind area behind the vehicle can be monitored in real time. That is to say, the video image acquisition module can acquire the video images acquired by the image acquisition devices installed in the plurality of blind areas. The number of the image acquisition devices can be decided by a user, so that each image acquisition device can be independently installed and used, and the system can also independently control each image acquisition device.
The image processing module 102 is used for processing the blind area video image and the reversing video image according to the transmission mode of the video image and sending the processed images to the transmission control module; when the blind area video image is an analog signal, the blind area video image is sent to a transmission control module; when the blind area video image is a digital signal, the transmission mode of the blind area video image is converted into an analog signal and then the analog signal is sent to the transmission control module.
The image processing module is mainly used for processing the video images acquired by the video image acquisition module. When the image processing module acquires the blind area video image sent by the video image acquisition module, the transmission mode of the blind area video image is judged firstly. If the transmission mode of the blind area video image is an analog signal, the blind area video image can be directly output. Specifically, the image processing module can directly send the blind area video image to the video conversion chip, and the video conversion chip performs optimization processing on the blind area video image, for example, the definition, brightness, color saturation, contrast and the like of the blind area video image are optimized, and then the optimized blind area video image is sent to the transmission control module. If the transmission mode of the blind area video image is digital signals, the transmission mode of the blind area video image can be converted into analog signals, then the analog signals are sent to a video conversion chip to optimize the blind area video image, and the optimized blind area video image is sent to a transmission control module. If the reversing video acquired by the image processing module is a reversing video image carried by the vehicle when leaving the factory, the reversing video image can be accessed into the image processing module, and according to a screen video transmission mode set when the vehicle leaves the factory: the CVBS or LVDS signals and other blind area video images are accessed into the image processing module and converted into CVBS or LVDS signals to be sent to the transmission control module. Furthermore, the blind area video image can be converted into an LVDS signal from an analog signal or a digital signal according to the video transmission mode requirement of the central control display screen of the current vehicle, and then the LVDS signal is sent to the transmission control module.
And the transmission control module 103 is used for acquiring a starting signal and a driving signal of the vehicle and sending the corresponding blind area video image or the corresponding reversing video image to the display module according to the starting signal and the driving signal.
After the transmission control module acquires the blind area video image or the reversing video image sent by the image processing module, the corresponding blind area video image or the reversing video image can be sent to the display module to be displayed according to the acquired vehicle starting signal and the acquired driving signal.
In one embodiment, the transmission control module 103 is further configured to obtain current gear information of the vehicle; and when the vehicle is detected to be in a forward gear, acquiring a blind area video image of the first blind area.
The transmission control module can also send the corresponding blind area video image or the reversing video image to the display module according to the acquired driving signal of the vehicle. When the transmission module acquires the current gear engaging information of the vehicle and detects that the gear engaging information is a forward gear, the transmission module can acquire a blind area video image acquired by the image acquisition equipment of the first blind area, namely a video image in front of the vehicle.
In one embodiment, the transmission control module 103 is further configured to control the display module to display the blind area video image of the first blind area according to the preset display time, send a close instruction to the image capturing device of the first blind area after the preset display time is reached, and stop transmitting to the display module.
When the vehicle is in the fender that advances, transmission module can directly send the blind area video image who acquires first blind area to the display module when showing, promptly, when the vehicle was in the fender that advances, transmission control module can control the demonstration of display module. The display time is limited to a certain extent, so that the transmission control module can control the display module to display the blind area video image of the first blind area according to the preset display time. After the time that the display module displays the blind area video images of the first blind area reaches the preset display time, the transmission module sends a control closing instruction to the image acquisition equipment of the first blind area, so that the image acquisition equipment of the first blind area stops video acquisition and transmission, and meanwhile, the transmission module also stops transmission to the display module.
In one embodiment, the transmission control module preferentially obtains a vehicle start signal, determines whether the vehicle is ignited to start, and determines an ACC state of the vehicle, performs on-off control, and if it is determined that the vehicle is started and the ACC state of the vehicle is turned on, may immediately send a high level signal to an image capturing device of a first blind area, i.e., a vehicle front camera, and the vehicle front camera starts to capture a video image in front of the vehicle in real time. Meanwhile, the transmission control module can also start to take over the video channel of the control display screen, and immediately control the display screen to display the blind area video image of the first blind area, namely display the video image before the vehicle, which is shot by the camera before the vehicle. The displayed time can be controlled by a timer in the transmission module, the time of the timer can be configured in a self-defining mode, for example, the time can be set to be 10 seconds or 15 seconds, namely, the transmission module can control the video image before the vehicle is displayed on the display screen for 10 seconds or 15 seconds immediately after the vehicle is started and the ACC state of the vehicle is started, and when the specified time is reached, the transmission control module immediately stops transmitting the video image to the display module, and meanwhile, the central control display recovers an own control menu. It is characterized in that: the vehicle is ignited and started, the vehicle immediately enters the forward-looking blind area video image, and exits from the forward-looking blind area video image after the set time.
In one embodiment, the image processing module and the transmission control module may be combined, that is, the image processing module may perform the above operations, for example, after the vehicle is started and the ACC state of the vehicle is turned on, the image processing module controls the display operation of the display screen, and after the specified time is reached, the image processing module stops controlling the display screen of the display module, and the display module controls the display of the display screen by itself.
In one embodiment, the transmission control module 103 is further configured to acquire a reverse video image and send the reverse video image to the display module when the vehicle is detected to be in a reverse gear.
When the transmission control module detects that the vehicle is in reverse gear, the reverse video image shot by the reverse camera can be acquired and sent to the display module to be displayed on the display screen. Specifically, when the transmission control module acquires a reversing signal of a vehicle, two modes can be provided, wherein the first mode is that the transmission control module is directly connected with a reversing detection line of a vehicle body through the reversing detection line of the system to intercept the reversing signal of the vehicle; and the second method is to obtain the backing signal of the vehicle by the communication between the system CAN analysis module and the vehicle body CAN bus. Can (controller Area network), is a serial communication protocol that is ISO international standardization. Because the reversing camera is generally powered by the reversing lamp power supply, as long as a reversing signal is detected, the reversing lamp power supply can immediately supply power to the reversing camera and work, and the reversing video image is sent to the display screen by the transmission control module so as to display the reversing camera video image.
In this embodiment, the display screen may be a central control display screen of the vehicle, or a central control navigation screen installed after the vehicle leaves the factory. That is to say, when the vehicle has a central control display screen, the video images of the other blind areas can be displayed on the display screen through the video channel of the original vehicle backing image. When the additional central control display screen is used for displaying the blind area video images, the blind area video images can be transmitted to the display screen through the additional video transmission channel of the additional display screen to be displayed.
In one embodiment, the transmission control module 103 is further configured to send a collecting instruction of a blind area video image of a second blind area to the image processing module when the driving signal of the vehicle is detected to be a left turn signal; the image processing module 102 is further configured to immediately acquire a blind area video image of the second blind area to the transmission control module; the transmission control module 103 is further configured to send a collecting instruction of the blind area video image of the third blind area to the image processing module when detecting that the driving signal of the vehicle is a right turn light signal. The image processing module 102 is further configured to immediately acquire a blind area video image of a third blind area to the transmission control module; the transmission control module 103 is further configured to send the blind area video image of the second blind area or the blind area video image of the third blind area collected by the image processing module to the display module for displaying.
When the transmission control module detects that the driving signal of the vehicle is a left turn light signal, a collecting instruction of the blind area video image of the second blind area can be sent to the image processing module, and the image processing module can immediately send the blind area video image of the second blind area to the transmission control module after processing. Specifically, after the left turn signal lamp is turned on to the vehicle, the transmission control module can detect that the running signal of vehicle is the left turn signal lamp signal to left side camera, the image acquisition equipment of second blind area sends high level signal promptly, and left side camera begins the collection work of video image. Meanwhile, the transmission control module transmits the immediately acquired left blind area video image sent by the image processing module to the display module and displays the left blind area video image on the display screen. When the left turn light signal of the vehicle stops, the transmission control module can also send a low level signal to the left camera to control the left camera to stop image acquisition, and meanwhile, the transmission control module can also stop controlling the display module.
When the transmission control module detects that the driving signal of the vehicle is a right turn light signal, the same processing flow is performed as when the driving signal of the vehicle is a left turn light signal, and the difference is that when the transmission module detects that the driving signal of the vehicle is a right turn light signal, a collecting instruction of the blind area video image of the third blind area is sent to the image processing module, the display screen of the display module is controlled, and the obtained blind area video image of the third blind area is displayed on the display screen in real time. Similarly, the transmission control module can also control the image acquisition equipment of the third blind area, namely the right camera and the display screen of the display module. And will not be described in detail herein. The transmission control module can also obtain a control instruction by short pressing the double flashing lamps of the vehicle, open the first blind area camera according to the control instruction and transmit the first blind area video image to the display module.
In one embodiment, when a user presses the double flashing lamps for a short time, the transmission control module can also acquire the state that the vehicle turns on the double flashing signal lamps, and can send a high-level signal to the front camera, namely, the image acquisition device of the first blind area, the front camera can start the acquisition work of the video image, and the transmission control module can also control the display screen of the display module, so that the video image in front of the vehicle acquired by the front camera can be displayed on the display screen in real time. When the user triggers two flashing light signals once more, then two flashing light signals are closed, and transmission module also can send low level signal to the camera forward, the camera outage before the control and stop work, and simultaneously, transmission module also can stop control display module's display screen to can show self operation menu on the display screen.
For convenience, the image processing module and the transmission control module may be combined, and when the transmission control module controls the display screen of the display module, the image processing module may also control the display screen.
And the display module 104 is configured to display the received blind area video image or the reverse video image.
When the display module includes, but is not limited to, a central control display screen of the original vehicle and a central control display screen of a display additionally installed, all the blind area images are used for displaying the received blind area video images or the reverse video images through the central control display screen, specifically, the display screen for displaying the blind area video images is used for displaying the blind area video images, and the display screen does not need to be divided into areas, that is, 2 or more than 2 blind area video images are not displayed on the display screen for displaying the blind area video images at the present time, but displays the present blind area video images in a full screen manner. Furthermore, the blind area video image and the backing video image displayed on the display screen are not subjected to image splicing processing and are real-time images.
In an embodiment, the display module 104 is further configured to obtain a control instruction triggered by a steering wheel key, and display a corresponding blind area video image according to the control instruction.
In this embodiment, the control of the display screen may also be triggered by a key on the steering wheel. That is to say, under normal circumstances, the user may not control the display of the display screen, and the blind area video images or the reverse video displayed on the display screen are automatically switched according to the current driving state of the vehicle, so that the user can see the video images of each blind area in time. Of course, the user may also trigger the image displayed on the display screen through a key on the steering wheel according to the needs of the user, for example, pressing a key to display a left blind area video image, and the like. The specific key settings can be configured according to the user definition.
