The invention provides an obstacle-based parking space identification method, and the method comprises the steps: starting a parking space detection program, and obtaining obstacle distance data; converting the obstacle distance data into a parking space detection coordinate system to obtain an obstacle distance point set; fitting the obstacle distance point set according to a preset rule to obtain a feature line segment set; calculating the length and slope of each feature line segment in the feature line segment set; and identifying whether a parking space exists and the parking space type according to each feature line segment. According to the invention, accurate identification of the parking space is realized.

    本发明提供基于障碍物的车位识别方法,方法包括:启动车位检测程序,获取障碍物距离数据;将所述障碍物距离数据转换到车位检测坐标系中,得到障碍物距离点集;将所述障碍物距离点集按照预设规则进行拟合,得到特征线段集;计算所述特征线段集中各特征线段的长度及斜率;根据各特征线段识别是否存在车位及车位类型。本发明实现了车位的准确识别。
