Abstract

The invention provides a vehicle-mounted camera angle calibration method, a terminal and a storage medium. The mounting position of a camera on a vehicle is fixed, a world coordinate system, a camera coordinate system, an image plane coordinate system and a pixel coordinate system are predefined, and the method comprises the following steps: obtaining a boundary line of a vehicle body and a road in an image according to the image shot by the camera; obtaining a calibration value of a roll angle and a calibration value of a yaw angle of the camera according to a mapping relation of the boundary line in the world coordinate system and the pixel coordinate system; obtaining two lane lines in the image according to the image; and according to the mapping relation of the two lane lines in the world coordinate system and the pixel coordinate system, obtaining the calibration value of the pitch angle of the camera. The application scene of camera angle calibration can be enlarged.

Description

technical field [0001] The present invention relates to the technical field of automatic driving and assisted driving, and in particular to a vehicle-mounted camera angle calibration method, a terminal and a storage medium. Background technique [0002] In automatic driving and assisted driving products, the calibration of camera external parameters is the basis of computer vision applications. Camera extrinsic parameters include the pose of the camera relative to the world coordinate system when capturing images, such as roll angle, yaw angle, and pitch angle. [0003] Generally, the traditional camera calibration method needs to use a specific calibration object with known size. By establishing the correspondence between the point on the calibration object with known coordinates and its image point, a certain algorithm is used to obtain the external parameters of the camera. The calibration accuracy of this method depends on Due to the dimensional accuracy of the calibrat...
