Embodiment 1

[0047] figure 1 A schematic diagram of the vehicle violation evidence collection process provided by the embodiment of the present invention, the process includes the following steps:

[0048] S101: Carry out vehicle recognition in each frame of image collected by the image collection device, and use a target tracking algorithm to determine the driving trajectory of each vehicle.

[0049] S102: For each vehicle, when the number of pixels in the license plate area of ​​the vehicle is greater than a preset number threshold, obtain a valid license plate image of the vehicle; Violation valid image of the vehicle.

[0050]The vehicle violation evidence collection method provided by the embodiment of the present invention is applied to an electronic device, and the electronic device may be a PC, a tablet computer, or an image acquisition device. If the electronic device is a PC, tablet computer, etc., the image acquisition device will send each frame of image collected in real tim...

Embodiment 2

[0057] In the monitoring scene, in some cases, the monitored vehicle drives towards the lens of the image acquisition device, that is, the vehicle approaches the image acquisition device, and the image acquisition device can collect the information of the front of the vehicle at this time; in some cases, the monitored vehicle deviates from the image The lens of the acquisition device travels, that is, the vehicle leaves the image acquisition device. At this time, the image acquisition device can collect information on the rear of the vehicle. In order to ensure vehicle violation evidence collection in different monitoring scenarios, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, when the number of pixels in the license plate area of ​​the vehicle is greater than the preset number threshold, obtain the vehicle The effective image of the license plate; when the vehicle is determined to be in violation according to the driving track of...

Embodiment 3

[0064] In order to further obtain sufficient evidence for vehicle violations, on the basis of the above-mentioned embodiments, in the embodiment of the present invention, the determination of the vehicle violation according to the vehicle's driving track includes:

[0065] According to the running track of the vehicle, it is determined that the vehicle has violated the rules for changing lanes, or the vehicle has violated the rules for going against the road, or the vehicle has violated the rules for parking.

[0066] On expressway sections, the rules for judging violations are generally forbidden to change lanes, forbidden to go against the road, and forbidden to stop. In the embodiment of the present invention, according to the driving track of the vehicle, it is determined that the vehicle has violated the rules for changing lanes, or the vehicle has violated the rules, or the vehicle has violated the rules for parking.

[0067] Specifically, when the rules for judging viol...

Abstract

The invention discloses a vehicle violation evidence collection method, device, electronic equipment and storage medium, comprising: performing vehicle identification in each frame of image collected by an image acquisition device, and using a target tracking algorithm to determine the driving trajectory of each vehicle; For each vehicle, when the number of pixels in the vehicle’s license plate area is greater than a preset number threshold, obtain a valid image of the vehicle’s license plate; valid image. Because in the embodiment of the present invention, for each vehicle, when the number of pixels in the license plate area of ​​the vehicle is greater than a preset number threshold, a valid license plate image of the vehicle is acquired. When the vehicle violates the regulations, obtain the effective image of the violation of the vehicle. Since the number of pixels in the license plate area in the acquired valid image of the license plate is greater than the preset number threshold, it can be ensured that managers can clearly see the license plate information, making evidence collection sufficient.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method, device, electronic equipment and storage medium for obtaining evidence of vehicle violations. Background technique [0002] Traffic safety is an issue that everyone cares about, but in the traffic operation, some drivers often violate the rules and regulations, which brings hidden dangers to the safety of other drivers and passengers. and warnings to reduce the occurrence of violations. At present, the traffic bureau installs image acquisition equipment to capture and collect evidence for violations. Capture illegal evidence of vehicle violations. However, the existing evidence collection method is generally to capture the vehicle and obtain the image when it is recognized that the vehicle is in violation It can identify vehicle violations, but cannot see the license plate information, which will lead to insufficient evidence collection, and it is impossible to pun...
