The invention provides a retrograde driving state detection method and device based on a vehicle-mounted camera. The method comprises the following steps: acquiring video data to be identified of the vehicle-mounted camera of a target vehicle; obtaining lane line information and the position of a vanishing point in each frame of image based on the to-be-identified video data; obtaining a lane line type of each frame of image according to the lane line information; under the condition that the lane line type is a yellow solid line, determining that the frame image is a target image, and calculating the relative position of a vanishing point and the yellow solid line in the target image; and based on the relative positions of the vanishing points and the yellow solid line in the multiple frames of target images, determining that any two vanishing points are located on the two sides of the yellow solid line, and determining that the target vehicle is in a retrograde running state. The problem that in the prior art, vehicle converse driving state detection depends on data of a fixed camera on the road surface, and consequently state detection is difficult is solved.
本发明提供一种基于车载摄像头的逆行状态检测方法和装置,所述方法包括:获取目标车辆的车载摄像头的待识别视频数据;基于所述待识别视频数据,得到每帧图像中的车道线信息和消失点的位置;根据所述车道线信息得到每帧图像的车道线类型;在所述车道线类型为黄实线的情况下,则确定该帧图像为目标图像,并计算所述目标图像中消失点与黄实线的相对位置;基于多帧所述目标图像中消失点与黄实线的相对位置,确定存在任意两个消失点位于黄实线两侧的情况,则判定所述目标车辆处于逆行状态。解决了现有技术中车辆逆行状态检测依赖于路面上固定摄像头的数据,而导致的状态检测困难的问题。
