Assignee: TUSIMPLE, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 1:
2. The method of claim 1, wherein the extrinsic parameters of the at least two sensors are calculated by:
calculating, for each corner of the lane marker, a first loss function that computes a distance between a pixel location of a corner of the lane marker and previously stored 3D world coordinates of the corner of the lane marker obtained from the second set;
calculating, for each corner of the lane marker, a second loss function that computes another distance between 3D world coordinates of the corner of the lane marker obtained from the set and the previously stored 3D world coordinates of the corner of the lane marker obtained from the second set; and
estimating the extrinsic parameters for the camera and the LiDAR sensor based on the first loss function and the second loss function, respectively.
