Aiming at a mine semi-closed scene, the method has the characteristics of relatively fixed driving route, relatively high road closure and relatively few emergencies, information uploading rules of the vehicle-mounted camera of the unmanned mine car are optimized, and the similarity between the video frame information acquired by the vehicle-mounted camera in real time and the background video frame information is judged; whether an emergency situation occurs or not is judged, and video information collected by a vehicle-mounted camera in real time is uploaded only when the emergency situation occurs; furthermore, an emergency situation data set is established, secondary comparison is performed on the initial target video frame information and the emergency situation data set, and different similarities are set according to different influence degrees of each emergency situation on an unmanned driving decision, so that the uploaded video frame information can better reflect whether the emergency situation occurs or not, and the accuracy of the unmanned driving decision is improved. Through the optimized transmission method provided by the invention, the uploading amount of the video information is effectively reduced, the congestion degree of the network is reduced, and the information transmission time delay is also effectively reduced at the same time.
本申请针对矿山半封闭场景,具有行车路线较为固定,道路封闭性较强,突发情况较少的特点,对无人驾驶矿车车载摄像头上传信息规则进行优化,判断车载摄像头实时采集的视频帧信息与背景视频帧信息相似度,据此判断是否有突发状况发生,有突发状况发生才将车载摄像头实时采集的视频信息上传;更进一步地,通过建立突发状况数据集,并将所述初始目标视频帧信息与所述突发状况数据集进行二次比较,并根据每种突发状况对无人驾驶决策影响程度不同设置不同的相似度,从而使上传的视频帧信息更能反应出是否发生突发状况,通过本申请的优化传输方法,有效减少了视频信息的上传量,减少了网络的拥堵程度,同时也有效减少了信息传输时延。
