first embodiment

Please refer to FIG. 5 . FIG. 5 is a flowchart of the steps of the method for generating parking information provided by the first embodiment of the present invention. The method is applied to the car-finding system 10 , and the car-finding system 10 includes a server 300 , a mobile terminal 100 and an image acquisition device 200 that are connected to each other in communication. The specific flow of the method for generating parking information is described in detail below.

In step S110, the mobile terminal 100 monitors its motion mode.

In this embodiment, the motion modes include a driving mode, a parking mode, and a walking mode. The mobile terminal 100 can monitor its motion mode in real time. Of course, the mobile terminal 100 may also collect motion patterns after receiving a preset trigger instruction. Wherein, the preset trigger instruction may be an input instruction of the user or an instruction triggered when the access of a communication signal is detected.

The following description will be given by taking the triggering instruction as an instruction triggered when the access of the communication signal is detected as an example. When the mobile terminal 100 detects the communication signal, it performs the motion mode monitoring work. The communication signal may be, but not limited to, a radio frequency signal, a GPS positioning signal, a wifi hotspot wireless signal, and the like. Because RF signals have their own characteristics, special connectors are required as transmission media when transmitting signals, so the hardware cost is relatively high. In a multi-layer three-dimensional parking area, if GPS positioning signals are used, precise positioning may not be possible when the GPS signal strength is weak. After long-term research by the inventor, it is found that the use of wifi hotspot wireless signals for motion mode monitoring has a better triggering effect.

In the following, the triggering of the motion mode monitoring using the wifi hotspot wireless signal is used as an implementation manner of this embodiment to explain:

In this embodiment, a certain number of wireless access points (APs) may be pre-arranged in the parking area to provide the mobile terminal 100 with wifi wireless signals, which can be used to locate the parking position. The mobile terminal 100 analyzes and records the signal strength information of the currently detected wifi hotspot, and can obtain the location information of the vehicle when parking based on the signal strength information of the wifi hotspot. Due to the influence of the density of wireless access point AP arrangement and external interference factors, the positioning accuracy will be deviated. In theory, the minimum accuracy can be within the error range of 3-5 meters. In addition to the above positioning method, the mobile terminal 100 can also upload the collected WiFi signal strength information to the server 300, and the server 300 executes the WiFi positioning algorithm, thereby making full use of the powerful computing power of the server 300 to obtain a more accurate parking position information.

Step S120 , when the moving mode is switched to the walking mode via the driving mode and the parking mode, the mobile terminal 100 sends the first parking information to the server 300 .

In this embodiment, the first parking information includes the first parking time, the departure time of the first vehicle owner, and location information. When it is detected that the movement mode is switched from the driving mode to the parking mode, the mobile terminal 100 records the time at this time as the first parking time, and records the detected wifi signal strength information. When switching from the parking mode to the walking mode is detected, the mobile terminal 100 records the time at this time as the departure time of the first vehicle owner, and collects the WiFi signal strength information during this period of time in the parking mode, and analyzes the parking position according to the WiFi positioning algorithm. information. The mobile terminal 100 sends the first parking information generated by the combination of the first parking time, the first vehicle owner's departure time and the location information to the server 300 .

Next, we will introduce how the mobile terminal 100 realizes the judgment of the motion mode.

In this embodiment, the mobile terminal 100 monitors and analyzes the movement pattern of the mobile terminal 100 and records the relevant time. Specifically, by monitoring the data collected by the motion sensor 150 in real time, the motion acceleration values in three dimensional directions are calculated and obtained, and the motion acceleration values in the three dimensional directions respectively refer to the acceleration values in the front and rear directions (for example, AcceX), acceleration values in the left and right directions value (eg, AcceY) and acceleration value in the up and down direction (eg, AcceZ). Acceleration values in three directions are recorded in real time and stored in the acceleration sets corresponding to the three directions: front and rear sets (eg, AcceXSet), left and right sets (eg, AcceYSet), and up and down sets (eg, AcceZSet). According to the acceleration values in the front and rear sets and the left and right sets, the average speed in the horizontal direction (for example, HASpeed) and the motion direction (for example, MDirection) are analyzed and calculated. The average speed and movement direction are recorded in real time, and stored in the corresponding speed set (eg, HASpeedSet) and direction set (eg, MDirectionSet).

During the driving process, the vehicle generally accelerates in a slowly changing horizontal direction, and performs segmented linear motion according to the lane. Therefore, by analyzing whether the horizontal acceleration change frequency of the speed set is less than the horizontal specified threshold (for example, HA), By analyzing whether the movement direction of the direction set is in a segmented straight line state, it can be determined whether it is currently in a driving state.

During the walking process, the change of the pedestrian's horizontal acceleration will have a certain periodic change, and the change frequency is much faster than that of the vehicle when driving. Therefore, by analyzing whether the change frequency of the horizontal acceleration in the speed set exceeds the specified horizontal threshold, It can be judged whether it is currently in a walking state.

The judgment basis of the three motion modes is defined below according to the specific conditions of the driving state, the walking state and the motion acceleration values in the three dimensional directions:

In this embodiment, the front and rear sets, the left and right sets, and the upper and lower sets are respectively set with front and rear specified thresholds (eg, X), left and right specified thresholds (eg, Y), and upper and lower specified thresholds (eg, Z) for comparison. The data in the front and rear sets, the left and right sets, and the upper and lower sets of acceleration values that are smaller than the respective corresponding specified thresholds are defined as zero values, otherwise, they are defined as non-zero values.

If in a detection period, non-zero values persist in the front and rear sets and/or left and right sets, and there are only sporadic non-zero values in the upper and lower sets, and it is judged that the current driving state is based on the speed set and the direction set, then the vehicle is currently in driving state. model.

If in a detection period, there are only sporadic non-zero values in the front and rear sets, left and right sets, and upper and lower sets, or non-zero values persist in the front and rear sets, left and right sets, and upper and lower sets, and the values of the upper and lower sets show irregular changes, it is considered that It is now in park mode.

If in a detection period, non-zero values persist in the front and rear sets, left and right sets, and upper and lower sets, and the values of the upper and lower sets show periodic changes, and the current state of walking is judged according to the speed set, it is considered to be walking at this time. model.

In this embodiment, considering that the data of the motion sensor 150 fluctuates to a certain extent, in the actual analysis, it is necessary to analyze the data less than the specified threshold as the measurement result, so that each suitable specified threshold parameter is selected.

Step S130 , the image collection device 200 collects images, obtains second parking information according to the collected images, and sends the second parking information to the server 300 .

In this embodiment, the second parking information includes the second parking time, the second vehicle owner's departure time, and the parking space number. A certain number of image capture devices 200 are pre-arranged in the parking lot according to the area, each image capture device 200 covers a parking area, and the area includes several parking spaces. Each image acquisition device 200 records the parking space number of each parking space in the coverage area.

In this embodiment, the parking spaces corresponding to each area are captured and calibrated on the screen by manual calibration or self-calibration by the image acquisition device 200 in advance, and a corresponding parking space number is assigned to each parking space. The parking spaces in each parking area are free at initialization. When a vehicle enters the parking area for parking, the image acquisition device 200 detects that a moving object enters the parking area and stops, records the time information at this time as the second parking time, and marks the corresponding parking space area as being in a parking state. When it is detected that a person leaves the parking space area in the parking state, the time information at this time is recorded as the departure time of the second vehicle owner. When it is detected that a vehicle leaves, the corresponding parking space is marked to handle the idle state. The image acquisition device 200 combines the second parking time corresponding to each vehicle, the departure time of the second vehicle owner and the parking space number to generate the second parking information of the corresponding vehicle.

The above process can be obtained by performing image analysis on the video collected by the image collection device 200 , and the specific image analysis technology may refer to the prior art, which will not be repeated here.

Step S140, the server 300 matches the first parking information and the second parking information, and when the matching is successful, generates third parking information.

In this embodiment, the third parking information includes mobile terminal 100 information, parking time and parking space number. The server 300 receives the first parking information sent by all the mobile terminals 100, sorts each piece of first parking information according to time, and aggregates the results into a first parking set (for example, APPParkSet). The record includes the following information: the first parking time, the first vehicle owner's departure time, and location information.

The server 300 receives the second parking information sent by all the image capturing devices 200, sorts each piece of second parking information according to time, and aggregates the results into a second parking set (eg, CamParkSet). Each record in the second parking set includes the following information: the second parking time, the second vehicle owner's departure time, and the parking space number.

The server 300 finds the most matching pair as the best matching record by matching the first parking time and the first vehicle owner's departure time in the first parking set with the second parking time and the second vehicle owner's departure time in the second parking set , for each pair of best matching records, a third parking information is generated. Each piece of third parking information includes: mobile terminal 100 information, parking time and parking space number. The mobile terminal 100 information includes the vehicle owner's departure time and location information monitored and recorded by the mobile terminal 100 .

In this embodiment, the work of communication connection and information transmission among the server 300 , the mobile terminal 100 and the image acquisition device 200 can be realized by wifi wireless signals.
