Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] Different from the traditional vehicle detection methods, the convolutional neural network has a certain degree of invariance to geometric transformation, deformation, and illumination, which effectively overcomes the difficulties caused by the changing appearance of the target, and can be adaptively constructed under the drive of training data. Feature description, with higher flexibility and generalization ability. The invention detects the position of the target vehicle through the convolutional neural network model, and then detects illegal parking, thereby greatly improving the detection accuracy and detection speed.

[0044] Such as figure 1 As shown, the present invention provides a kind of vehicle illegal parking detection method based on convolutional neural network, comprises following simple steps:

[0045] Initialize the parking violation...

Abstract

The invention provides a vehicle illegal parking detection method based on a convolutional neural network. The method comprises the steps that (1) a no-parking region in a video frame image, a presetviolation early-warning threshold value and a preset violation threshold value are set respectively; (2) target vehicles in the set no-parking region are detected through a convolutional neural network model, and vehicle information is recorded; (3) whether a current vehicle set A in the step (2) and a historical vehicle set B contain vehicles which can be matched is judged; (4) whether delay timeof a current target vehicle Ai is greater than the preset violation early-warning threshold value in the step (1) is judged; (5) whether the early-warned delay time of the current target vehicle Ai is greater than the preset violation threshold value in the step (1) is judged; and (6) the vehicle information in the historical vehicle set B is updated, a next video frame image is input, the step (2) is entered to start vehicle violation detection on the next video frame image, and the operation from the step (2) to the step (5) is repeated.

Description

technical field [0001] The invention relates to the technical fields of intelligent transportation systems, deep learning and image recognition, and in particular to a method for detecting illegal parking of vehicles based on a convolutional neural network. Background technique [0002] With the progress and development of society, the number of urban motor vehicles is increasing, and the economic losses and casualties caused by road traffic accidents are also increasing. Controlling traffic accidents has become a problem that traffic management departments pay more and more attention to, and the primary cause of traffic accidents is The reason is automobile violations. As a common violation, illegal parking will not only cause traffic jams and traffic paralysis, but may even cause serious traffic accidents. At present, the detection method for illegal parking is mainly by manual detection. However, this requires arranging personnel to manually monitor all places where park...
