The invention provides an intersection steering angle calculation method and system. The method comprises the following steps: acquiring an intersection main path road vector end point angle; obtaining a leftmost lane vector form point of an intersection departure road, and calculating an angle at a departure path end point based on a course angle accumulated value of the lane vector form point; and calculating an intersection steering angle according to a difference value between the intersection main path road vector end point angle and the departure path end point angle. By means of the scheme, the accuracy of intersection steering angle calculation can be effectively improved, and good data tolerance capacity is achieved.

    本发明提供一种路口转向角计算方法及系统,该方法包括:获取路口主路径道路向量终点角度;获取路口脱出道路最左侧车道向量形点,基于车道向量形点的航向角累积值计算脱出路径终点处角度;根据路口主路径道路向量终点处角度和脱出路径终点处角度的差值计算路口转向角度。通过该方案可以有效提高路口转向角计算的准确性,并具有良好的数据容差能力。
