Abstract
The present disclosure provides a method and an apparatus for trailer angle measurement, as well as a vehicle, applied in a vehicle including a tractor and a trailer. At least one LiDAR is provided on each of two sides of the tractor. The method includes: obtaining, an initial trailer model containing initial point cloud data; controlling the to emit laser light; controlling each of the LiDARs to receive a corresponding point cloud reflected by the surface of the trailer; and calculating a trailer angle based on the point cloud data and the initial point cloud data using a point cloud matching algorithm. With the embodiments of the present disclosure, fast and accurate measurement of a trailer angle can be achieved with a simple structure.
