bool SimOneAPI::GetLaneST(const SSD::SimString &id, const SSD::SimPoint3D &pos, double &s, double &t)¶

获取相对于车道虚拟中心线的ST坐标

Get the ST coordinates relative to the lane's virtual centerline.

此函数用于获取输入点相对于指定车道中心线的[s, t]坐标值对

This function is used to obtain the [s, t] coordinate pair of the input point relative to the centerline of the specified lane.

参数:¶

const SSD::SimString &id¶

[in]

输入的车道ID，格式为roadId_sectionIndex_laneId

Input lane ID, formatted as roadId_sectionIndex_laneId.

const SSD::SimPoint3D &pos¶

[in]

输入的3D位置

Input 3D location.

double &s¶

[out]

输入点在s-t坐标系统中相对于指定车道s值

The input point's s value in the s-t coordinate system, relative to the specified lane.

double &t¶

[out]

输入点在s-t坐标系统中相对于指定车道t值

The input point's t value in the s-t coordinate system, relative to the specified lane.

返回:¶

如果地图中存在指定的车道则返回true，否则返回false

Returns true if the specified lane exists in the map, else returns false.
