The invention discloses a roadside parking berth abnormity identification method and device based on a berth number. The method comprises the following steps: acquiring a plurality of video frames, and acquiring a berth number position and berth number information corresponding to each video frame according to the plurality of video frames; according to the berth number positions, the berth number area intersection-union ratio corresponding to the berth number information in the two adjacent video frames is calculated; if the intersection-to-union ratio of the berth number area is smaller than a preset threshold value, the roadside berth corresponding to the berth number information is abnormal, and otherwise, the roadside berth is not abnormal; if the roadside parking space is abnormal, whether an obstacle exists at the parking space number position corresponding to each video frame in the two adjacent video frames is judged; and if the obstacle exists at the position of the berth number, calculating the area intersection-to-union ratio of the berth number corresponding to the berth number information in the video frame and the next video frame, judging whether the roadside berth corresponding to the berth number information is abnormal or not, and if the obstacle does not exist at the position of the berth number, judging that the roadside berth is abnormal.

    本申请公开一种基于泊位号码的路侧停车泊位异常识别方法及装置。方法包括:获取多个视频帧,并根据多个视频帧,获取每个视频帧对应的泊位号码位置与泊位号码信息;根据泊位号码位置,计算相邻两个视频帧中泊位号码信息对应的泊位号码面积交并比;若泊位号码面积交并比小于预设阈值,则泊位号码信息对应的路侧泊位异常,否则,路侧泊位无异常;若路侧泊位异常,则判断相邻两个视频帧中每个视频帧对应的泊位号码位置是否存在障碍物;若泊位号码位置存在障碍物,则计算视频帧与下一个视频帧中泊位号码信息对应的泊位号码面积交并比,并判断泊位号码信息对应的路侧泊位是否异常,若泊位号码位置不存在障碍物,则路侧泊位异常。
