The invention discloses an obstacle avoidance method and system based on automatic driving, and particularly relates to the technical field of automatic driving, and the system comprises a data collection module, an information fusion module, a high-precision positioning module, an image contour matching module, an obstacle avoidance path planning module, a safe distance module and a parking brake module. The data acquisition module performs data acquisition through data information of various sensors installed on a vehicle, and the information fusion module realizes fusion of road signals by receiving the data information of the data acquisition module. The binarized image contours are used as features through a sample matching method of image features, comparison of obstacles is carried out, the problem that in the prior art, obstacles cannot be recognized in complex road sections during automatic driving is solved, and the problem that in the prior art, emergency situations cannot be faced is solved through a parking braking module.

    本发明公开了一种基于自动驾驶的避障方法及系统,具体涉及自动驾驶技术领域,包括数据采集模块、信息融合模块、高精定位模块、图像轮廓匹配模块、避障路径规划模块,安全距离模块以及停车制动模块,所述数据采集模块通过安装在车辆上的各类传感器的数据信息进行数据采集,所述信息融合模块通过接收所述数据采集模块的数据信息实现对道路信号的融合。通过图像特征的样本匹配方法将二值化的图像轮廓作为特征,进行障碍物体的比对,克服了现有技术中自动驾驶在复杂路段中无法识别障碍物的问题,通过停车制动模块克服了现有技术中无法面对紧急突发状况的问题。
