Claim 20:
21. The non-transitory computer-readable storage medium of claim 11, wherein the at least one program including the instructions which, when executed using the at least one processor, cause the first device to further perform operations comprising:
receiving, using the at least one processor, a second initial extrinsic calibration of a second camera having a second sensor, wherein the second initial extrinsic calibration includes a rotation matrix and an initial translation matrix and is based on a first position of the second sensor when the second camera captures an initial image;
determining, using the at least one processor, a second translation of the second sensor based on the second position thereof when the second camera captures a first image, the second position being different than the first position;
determining, using the at least one processor, a second extrinsic translation shift based at least upon the second translation, wherein the second extrinsic translation shift represents a first net translation between the first position and the second position of the second sensor; and
updating, using the at least one processor, the second initial extrinsic calibration to yield a second modified extrinsic calibration for the second camera based on the second extrinsic translation shift, wherein the second modified extrinsic calibration includes the rotation matrix and a second adjusted translation matrix given by the summation of the second extrinsic translation shift with the initial translation matrix.
