A method for measure and drawing high-precision map data base on high-precision trajectory data

A method for measure and drawing high-precision map data base on high-precision trajectory data includes such steps as collecting image information and GPS information base on image acquisition equipment, calibrating image information by camera to obtain camera parameters and distortion parameters, measuring high-precision trajectory data based on high-precision trajectory data to obtain high-precision map data, measuring high-precision trajectory data based on high-precision trajectory data to obtain high-precision map data. Step S2, according to the GPS information of the image acquisition point and the camera parameters, generating a rotation matrix R of the acquisition point coordinates in the world coordinates; 3, carry out de-distortion processing on image information accord to camera parameters and distortion parameters to obtain a distortionless image; 4, obtaining pixel coordinates on that distortion-free image correspond to the geometric shape mark points on the distortion-free image; 5, generating
