The invention relates to the technical field of automatic driving, in particular to a surrounding road condition analysis automobile automatic driving system which comprises an environment sensing data acquisition module, a data processing and edge extraction module, an object recognition module and a safety distance early warning module. The point cloud data is projected to a two-dimensional plane, then edge information is extracted, and after extraction, the object recognition module matches and calculates object categories corresponding to the object edge information in the point cloud data and the digital signals, senses the distances of different objects between corresponding automobiles in the cloud point data, and sets a similarity threshold value and a reflection threshold value; and the edge information of the object in the data processing and edge extraction module is determined again through the similarity threshold value and the reflection threshold value, so that the safe distance early warning module can more accurately know the distances between different objects and the automobile in the new digital image.

    本发明涉及自动驾驶技术领域,具体地说,涉及一种周围路况分析的汽车自动驾驶系统,包括环境感知数据采集模块、数据处理与边缘提取模块、物体识别模块和安全距离预警模块,通过数据处理与边缘提取模块感知点云数据和数字信号,将点云数据投影到二维平面上,而后提取边缘信息,提取后物体识别模块匹配计算点云数据和数字信号中物体边缘信息对应的物体类别、感知不同物体在云点数据中对应汽车之间的距离,并设定相似度阈值和反射阈值,通过相似度阈值和反射阈值再次确定数据处理与边缘提取模块中物体的边缘信息,使得安全距离预警模块能够更加准确的得知新数字图像中不同物体和汽车之间的距离。
