The invention relates to the technical field of video analysis, and discloses an algorithm for judging vehicle illegal parking through vehicle thermodynamic diagram statistics, which sequentially comprises the steps of video frame extraction, road area recognition, vehicle recognition, thermodynamic area acquisition, candidate target confirmation and illegal parking judgment. According to the method and the device, after the vehicle target is identified, the strategy of tracking the vehicle is not directly adopted, the thermodynamic diagram of a period of time is counted, the area with the high hot spot is obtained through the thermodynamic diagram statistics, then vehicle target matching is carried out on the area with the high hot spot so as to obtain the suspicious candidate target, and then template matching is carried out on the candidate target for a period of time. And judging whether the position is moved so as to obtain a conclusion whether the vehicle is illegally parked or not. Tracking targets can be effectively reduced through thermodynamic diagram statistics, the algorithm calculation amount can be reduced, then target movement judgment is carried out through an image matching algorithm instead of a tracking algorithm, and the detection rate is improved.
本申请涉及视频分析技术领域,公开了一种通过车辆热力图统计判断车辆违停的算法,依次包括:视频抽帧、识别道路区域、识别车辆、热力区域获取、候选目标确认和违停判定。本申请,对车辆目标识别后,不直接采用对车辆跟踪的策略,而是统计一段时长的热力图,通过热力图统计得到热点高的区域,然后对热点高的区域来进行车辆目标的匹配,从而得出可疑的候选目标,再对候选目标进行一段时长的模板匹配,判别其位置是否存在移动,从而得出其是否违停的结论。通过热力图统计能够有效的减少跟踪目标,可以减低算法计算量,然后通过图像匹配的算法而不依赖跟踪的算法来进行目标的移动的判别,提高检测率。
