The present disclosure provides a method and an apparatus for trailer angle measurement, as well as a vehicle, applied in a semi-trailer (20) including a tractor (201) and a trailer (202). At least one laser radar (203) is provided on each of two sides of a rear part of the tractor (201). A reflector (204) with a reflective surface is fixedly provided at a front part of the trailer (202), and the reflective surface faces the laser radars (203). The method includes: controlling (301) the laser radar (203) provided on each of the two sides of the rear part of the tractor (201) to emit laser light, such that the reflective surface of the reflector (204) reflects the laser light emitted by the laser radar (203); controlling (301) each of the laser radars (203) to receive a corresponding laser point cloud reflected by the reflector (204); and calculating (301) a trailer angle based on the corresponding laser point clouds received by the respective laser radars (203). The method and apparatus can increase the range of trailer angle measurement, such that the trailer angle can be measured even if the trailer angle is relatively large. In addition, the calculation is based on laser point clouds of a plurality of laser radars, such that the accuracy of the result can be improved.
