The invention discloses a roadside vehicle parking behavior detection method based on a high-order camera, and belongs to the field of roadside vehicle parking recognition. The method solves the problems of imprecise vehicle detection and high error correction cost of a parking space-dominated parking condition judgment method at present, and comprises the following steps: firstly, defining a parking space frame in a fixed camera picture, wherein the parking space frame represents a parking area; detecting and judging whether a moving object exists or not for each frame of image in the subsequent images; judging whether a moving frame and the parking space frame are overlapped or not, judging whether the moving object is a vehicle or not if the moving frame and the parking space frame areoverlapped, and acquiring a real outline of the moving object if the moving object is the vehicle, recording a moving track of the moving object by utilizing a tracker, and judging a vehicle behaviorby utilizing the overlap ratio of the real outline and the parking space frame and the moving track; otherwise, ignoring the frame of image; according to the method, the roadside vehicle parking condition can be judged more precisely, and the error correction cost is low.
本发明公开了一种基于高位摄像头对路边车辆停车行为的检测方法,属于路边车辆停车识别领域。本发明解决了目前以车位为主导的停车情况判断方法的车辆检测不精确以及纠错成本高的问题,包括:首先定义固定摄像头画面中的车位框,车位框即代表了停车区域;再对后续图像中的每一帧图像,检测判断是否有运动物体;接着判断运动框与车位框是否重叠,若重叠,则判断该运动物体是否为车辆,若为车辆,则获得该运动物体的真实轮廓以及利用追踪器记录该运动物体的运动轨迹,利用所述真实轮廓与车位框的重合度和所述运动轨迹判断车辆行为;否则忽略该帧图像;本发明能够更精确判断出路边车辆停车情况,且纠错成本低。
