Abstract
The invention relates to a method and a device for determining a vehicle parking attitude angle and a vehicle. The method comprises the following steps: acquiring contour point data of an obstacle within a preset distance of a parking space; an obstacle edge line segment is determined according to the contour point data, the obstacle edge line segment is used for representing the edge of an obstacle in a plane parallel to the parking space, the line segment length of the obstacle edge line segment is larger than a preset target length, and the obstacle edge line segment with the target length covers the multiple contour points; and according to the obstacle edge line segment, the parking attitude angle of vehicle parking is determined. According to the method, the edge of the obstacle is represented by the line segment with the target length, the influence of factors such as environmental noise and sensor errors can be reduced, and then the calculation accuracy of the vehicle parking attitude angle is improved.
