Embodiment

[0024] A method for detecting illegal parking based on deep learning, comprising the steps of:

[0025] Step 1. Designate a no-parking zone (NPZ, no parking zone) for the surveillance video.

[0026] Step 2. Access the real-time video screen or video, detect the vehicle in the video, and obtain the vehicle detection frame, specifically:

[0027] The video is input into the yolo-mini network model to detect the vehicle in the video screen. The yolo-mini network model uses yolo-tiny as the backbone network, and the two largest calculations (Bflops) of the 12th layer and the 21st layer are used. The convolution operation between the convolution filter F of the layer and the input feature X is modified from multiplication to the L1 distance, that is, the absolute value of the difference between F and X, and a BN layer is added to normalize the result , to ensure that the original activation function can be used normally, and the modified network is named yolo-mini.

Abstract

The invention discloses an illegal parking detection method based on deep learning. The method comprises the following steps: reading a video frame for detection; calculating a central point of the detected automobile detection frame; judging whether the central point is in a no-parking area or not, if so, judging whether the parking time exceeds a set value or not, and if not, reminding. According to the invention, through simplified modification of a yoto-tiny network structure, the speed of detecting a single type of targets is faster on the premise of not losing the precision; through binaryzation of the IOU, the calculation speed is significantly improved. Through a-IOU calculation, illegal parking can be more simply, conveniently and accurately determined. And by comparing the centerof the detection frame with the center stored in the set C, the tracking timing problem is simply solved.

Description

technical field [0001] The invention belongs to the field of video image processing and pattern recognition in computer vision, and relates to a method for detecting illegal parking based on deep learning. Background technique [0002] Today, the urban traffic problem has become a worldwide problem. Countries all over the world have spent a lot of manpower, material and financial resources on solving the urban traffic problem, but they cannot effectively solve this problem. Among them, the phenomenon of illegal parking is particularly serious with vehicles parked indiscriminately. A large number of vehicles occupy sidewalks and emergency passages, which bring huge harm and hidden dangers to traffic. The phenomenon of illegal parking in the city has become an important problem that needs to be solved urgently. At present, it mainly relies on camera manual monitoring and traffic police patrolling, which is not only inefficient, but also consumes too much manpower and material...
