The invention provides an illegal parking event identification method and system based on a global matching strategy. The method comprises the following steps: preprocessing an input image; vehicle target detection is carried out by the deep learning model; vehicle types and parking spaces are automatically grouped; the vehicle model is bound with the parking space; weighted parking space occupancy rate calculation: calculating the weighted parking space occupancy rate of each parking space, and constructing a weighted parking space occupancy rate matrix; s5, carrying out Hungary matching, taking the weighted occupancy rate matrix generated in the step S5 as a basis for calculating a Hungary matching cost matrix for a normal occupancy combination, carrying out a Hungary matching algorithm, and searching the most matched vehicle for each parking space; and carrying out novel distance calculation, and for an abnormally occupied combination, judging the parking space occupation state by calculating the closeness degree of the vehicle and the parking space area. According to the invention, missing detection and false detection of an illegal parking detection technology based on an AI vision algorithm are reduced; and the detection precision of uncivilized parking behaviors is improved.

    本发明提供了一种基于全局匹配策略的违停事件识别方法及系统,包括输入图像预处理;深度学习模型进行车辆目标检测;车型与车位自动分组;车型与车位进行绑定;加权停车位占用率计算,计算每个车位的加权停车位占用率,构建带权重车位占用率矩阵;进行匈牙利匹配,对正常占用组合,将步骤S5中生成的带权占用率矩阵作为计算匈牙利匹配代价矩阵的依据,进行匈牙利匹配算法,为每个停车位搜索到最匹配的车辆;进行新型距离计算,对于异常占用的组合,通过计算车辆与车位区域的接近程度来判断停车位占用状态。本发明降低了基于AI视觉算法的违停检测技术的漏检与误检;提高对不文明停车行为检测精度。
