Classification: CPC G  H | IPC G  H

Claim 13:
14. The non-transitory computer readable storage medium of claim 13, wherein the extrinsic parameters of the at least two sensors are calculated by:
calculating, for each of at least two corners of the lane marker, a first loss function that computes a distance between a location of a corner of the lane marker and the previously stored 3D world coordinates of the corner of the lane marker obtained from the second set;
calculating, for each of the at least two corners 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 first sensor and the second sensor based on the first loss function and the second loss function, respectively.
