The invention discloses a U-turn line control point enumeration method and system, a U-turn line construction method and a medium, and belongs to the technical field of automatic driving, and the method comprises the steps: determining a U-turn starting point and a U-turn ending point; selecting a first U-turn line control point; selecting a second U-turn line control point; selecting a third turn-around line control point; more than four U-turn line control points are selected, and a single first U-turn line control point, a single second U-turn line control point, a single third U-turn line control point and a single fourth U-turn line control point are selected for multiple times to be combined to obtain multiple groups of U-turn line control points. According to the technical scheme, when the U-turn line is generated, the multiple U-turn line control points are selected, then the selected U-turn line control points are used for determining the corresponding U-turn line according to the Bezier curve principle, the safety and feasibility of the U-turn line are guaranteed, the generated U-turn line conforms to the driving habit of a driver, and the driving experience of the driver is improved. And the driving experience is improved.

    本申请公开了一种掉头线控制点枚举方法、系统、掉头线构造方法及介质,属于自动驾驶技术领域,该方法包括确定掉头的起始点和终止点;选取第一掉头线控制点;选取第二掉头线控制点;选取第三掉头线控制点;选取多四掉头线控制点,多次选取单个第一掉头线控制点、第二掉头线控制点、第三掉头线控制点以及第四掉头线控制点进行组合,得到多组掉头线控制点。本申请实施例的技术方案在进行掉头线生成时,进行多个掉头线控制点的选取,然后利用选取的掉头线控制点利用贝塞尔曲线的原理确定出对应的掉头线,保证掉头线的安全性以及可行性,使得生成的掉头线符合驾驶员的驾驶习惯,提高驾乘体验。
