The invention discloses a U-turn line control point generation method and system, a U-turn line generation method and a medium, and belongs to the technical field of automatic driving, and the method comprises the steps: determining a first center point and a first preset range with the first center point as the center; determining a second center point and a second preset range taking the second center point as the center; determining a third center point and a third preset range taking the third center point as the center; determining a fourth central point and a fourth preset range taking the fourth central point as the center; and selecting one or more points in the first preset range, the second preset range, the third preset range and the fourth preset range for multiple times to obtain multiple groups of U-turn line control points. According to the method and the device, the subsequent central points and ranges are determined according to the first determined central points and ranges, so that the relation between the U-turn line control points during selection is enhanced, the availability of the U-turn line control points is improved, the generated U-turn line conforms to the driving habit of a driver, and the driving experience is improved.

    本申请公开了一种掉头线控制点生成方法、系统、掉头线生成方法及介质,属于自动驾驶技术领域,该方法包括:确定第一中心点及以第一中心点为中心的第一预设范围;确定第二中心点及以第二中心点为中心的第二预设范围;确定第三中心点及以第三中心点为中心的第三预设范围;确定第四中心点及以第四中心点为中心的第四预设范围;分别多次在第一预设范围、第二预设范围、第三预设范围以及第四预设范围内选取一个或多个点,得到多组掉头线控制点。本申请根据先确定的中心点和范围进行后续中心点和范围的确定,增强在掉头线控制点选取时之间的联系,提高掉头线控制点的可用性,使得生成的掉头线符合驾驶员的驾驶习惯,提高驾乘体验。
