The invention discloses a road surface obstacle detection method and device for counting vehicle behaviors based on a roadside unit, and relates to the technical field of information, and the method comprises the steps: obtaining a road surface image of a current frame; performing inter-frame difference on the pavement image of the current frame and a pavement image of a previous frame corresponding to the current frame to obtain a static grid region in the pavement image of the current frame; performing gray scale matching on the static grid area and a road surface reference image when no vehicle runs, and determining a to-be-detected obstacle according to a matching result; according to the target grid occupied by the to-be-detected obstacle in the current frame of road surface image and the perspective view corresponding to the road surface reference image, evaluating the interference degree of the to-be-detected obstacle to the actual passing of the vehicle; and carrying out vehicle early warning based on the interference degree. The vehicle does not need to be equipped with extra equipment during obstacle detection.

    本发明公开了一种基于路侧单元统计车辆行为的路面障碍物检测方法及装置,本发明涉及信息技术领域,其中包括:获取当前帧的路面图像;对所述当前帧的路面图像和所述当前帧对应的前一帧的路面图像进行帧间差分,得到所述当前帧的路面图像中的静态网格区域;将所述静态网格区域与无车辆行驶时的路面参照图像进行灰度匹配,并根据匹配结果,确定待检测障碍物;根据所述待检测障碍物在所述当前帧的路面图像中占据的目标网格,以及所述路面参照图像对应的透视图,评估所述待检测障碍物对车辆实际通行的干扰程度;基于所述干扰程度,进行车辆预警。本发明在进行障碍物检测时车辆无需额外配备设备。
