Specifically, when a vehicle enters/exits a parking monitoring area, it is classified into a normal case, an abnormal case, and an abnormal case.
Conventional case: (1) When a vehicle enters the parking space in a conventional mode, high-quality license plate information (first parking event information) is acquired through a detection area (a near-end parking space and a nearby area) of the first image acquisition device, license plate information, vehicle image information and snapshot time are acquired through the optimal license plate detection area 101, an entering license plate information reference table is generated, if the first image acquisition device tracks that the vehicle enters the parking space, the vehicle is judged to enter the parking space, and then the fourth image acquisition device controls the fourth image acquisition device according to instructions of the second control module
And adjusting the angle and the focal length to capture the image information of the vehicle, and acquiring parking evidence (second parking event information), wherein: the parking evidence comprises pictures of key points of vehicle entering and exiting, license plate pictures and license plate recognition results;
and generating third parking event information based on the entry license plate information reference table information, the acquired parking evidence information and the occurrence time period of the corresponding event, and sending the third parking event information to the background.
If the vehicle has left the detection area of the first image acquisition device, the first image acquisition device stops tracking and detecting the vehicle.
(2) If the vehicle enters the detection area (the far-end parking space and the nearby area) of the second image acquisition device, the second image acquisition device detects and tracks the vehicle, if the vehicle is tracked to enter the parking space, the second image acquisition device judges that the vehicle enters the parking space and sends the entering information of the vehicle to the main control device, and the second control module controls the fourth image acquisition device to take a candid photograph according to the information provided by the second image acquisition device, so that parking evidence (second parking event information) is obtained.
Based on the images of the overlapped area 102 acquired by the first image acquisition device and the second image acquisition device, the images are spliced into complete panoramic image information;
the parking event management module combines the acquired complete panoramic image information, the entry license plate information reference table information and the acquired parking evidence information into third parking event information, and sends the third parking event information to the background.
If a plurality of parking events occur in a short time, the first image acquisition device and the second image acquisition device detect that the parking events occur, the task scheduling module 604 performs scheduling calculation and controls the fourth image acquisition device to sequentially capture according to a calculation result, and complete parking event information is synthesized according to the given parking event information, captured parking event information and image information recorded by the storage module in a corresponding period;
when the complete parking event information is synthesized, the parking event management module matches an entering license plate information reference table, carries out fuzzy matching on the parking information according to time periods, license plate characters and vehicle images, if the matching can be achieved, gives out an optimal license plate recognition result according to the license plate information reference table, and merges the corresponding information of the license plate information reference table into the parking event information; the network communication module in the main control device sends the complete parking event information to the background;
therefore, when a vehicle enters the ground conventionally, most of the situations can snap the license plate at the optimal visual angle, and the accuracy of license plate recognition is improved.
When the vehicle is normally out of the field, vehicle departure information of the first image acquisition device or the second image acquisition device is acquired, and the main control device controls the fourth image acquisition device to adjust the angle and the focal length to snap according to the information acquired by the first image acquisition device or the second image acquisition device, so that parking evidence (wherein the parking evidence comprises pictures, license plate recognition results and the like of key points of vehicle out of the field) is acquired.
And the parking event management module combines the acquired vehicle departure information and parking evidence into third parking event information and sends the third parking event information to the background.
If the first image acquisition device and the second image acquisition device acquire vehicle departure information, the first image control module splices a complete panoramic image according to the overlapping area image and incorporates the complete panoramic image into third parking time information.
Similarly, if a plurality of parking events occur during departure, the first image acquisition device and the second image acquisition device detect that the parking events occur, the task scheduling module performs scheduling calculation, controls the second control module to control the fourth image acquisition device to sequentially capture according to the calculation result, and synthesizes third parking event information according to the given parking event information, the captured parking event information and the image information recorded by the storage module of the corresponding time period.
Examples
As shown in fig. 3 to 8, it is different from embodiment 1 in that: the system also comprises a third image acquisition device 3, wherein the third image acquisition device 3 is also arranged on the L-shaped monitoring rod, and if the vehicle leaves the field but the vehicle leaves the field after being identified by the third image acquisition device, the vehicle leaves the field according to the vehicle;
and the third image acquisition device acquires license plate information, vehicle image information and snapshot time of the vehicle off-site passing region through high-speed snapshot recognition, and generates an off-site license plate information reference table according to the license plate information, the vehicle image information and the snapshot time.
The parking event management module can match the outgoing license plate information reference table with license plate information of the vehicle which is judged to enter the parking event at regular time, if the outgoing license plate information reference table can be matched with the license plate information of the vehicle which is judged to enter the parking event, the outgoing parking event is judged, and the outgoing parking event information of the vehicle is incorporated into third parking event information; if the first image acquisition device and the second image acquisition device do not judge the departure of the vehicle, generating a departure record based on the snapshot result of the third image acquisition device, and merging the departure record into third parking event information to generate complete parking event information; if the vehicle is judged to leave the field before, the confidence of the departure judgment is further improved.
If the exiting license plate information reference table is not successfully matched with the license plate information of the vehicle judged to enter, the vehicle is possibly a passing vehicle, and the parking event information is not recorded.
Therefore, conventionally, when a vehicle that has detected an entrance exits, only when it is missed by the first image capturing device (or the second image capturing device) and not detected by the third image capturing device at the same time, a situation of missed recognition is likely to occur, which greatly reduces the situation of missed detection.
As shown in fig. 5, a plurality of groups of L-shaped monitoring rods are arranged on the road side, and the first image acquisition device in the front L-shaped monitoring rod can acquire the vehicle image information of the optimal license plate detection area, and can acquire the vehicle image information of the vehicle departure passing area covered by the third image acquisition device of the rear L-shaped monitoring rod at the same time, so that the vehicle image information acquired by the two groups of acquisition devices is compared and information complemented at any time, and the condition that the vehicle passing through the vehicle departure passing area covered by the third image acquisition device in the rear L-shaped monitoring rod is missed can be reduced or even avoided.
When the device is specifically arranged, under the condition that a plurality of groups of L-shaped monitoring rods are arranged on the road side, the third image acquisition device is not required to be installed on the L-shaped monitoring rods at the rear, and only the first image acquisition device on the L-shaped monitoring rods at the front is required to acquire the vehicle image information of the vehicle passing region after leaving the road.
Thus, the design reduces the installation cost of the equipment without affecting the overall parking management.
Examples

and generating third parking event information based on the first parking event information, the second parking event information and the time period of occurrence of the corresponding event, and sending the third parking event information to the background.
If the vehicle has left the detection area of the first image acquisition device, the first image acquisition device stops tracking and detecting the vehicle.
When the vehicle leaves the first image acquisition device and enters the detection area (the far-end parking space and the nearby area) of the second image acquisition device, the second image acquisition device detects and tracks the vehicle, if the vehicle is tracked to enter the parking space, the second image acquisition device judges the entrance of the vehicle and sends the entrance information of the vehicle to the main control device, the second control module controls the fourth image acquisition device to take a candid photograph according to the information provided by the second image acquisition device to acquire parking evidence (second parking event information),
based on the vehicle images of the overlapping area acquired by the first image acquisition device and the second image acquisition device, the vehicle images are spliced into complete panoramic image information;
