Claim One:
1. A method for multi-lens module alignment, adapted to perform alignment on a multi-lens module comprising a first lens and a second lens during manufacture, wherein the method comprises the following steps: capturing a calibration object by using the first lens and the second lens to accordingly generate a first calibration parameter set corresponding to the first lens and a second calibration parameter set corresponding to the second lens, wherein the first calibration parameter set comprises an intrinsic parameter and an external parameter of the first lens, wherein the second calibration parameter set comprises an intrinsic parameter and an external parameter of the second lens, and wherein the external parameter of the first lens and the external parameter of the second lens are associated with a common reference coordinate system; capturing a target object by using the first lens and the second lens, and processing images of the target object respectively captured by the first lens and the second lens by using the first calibration parameter set and the second calibration parameter set to generate rectified images; and adjusting and aligning the first lens and the second lens according to the rectified images.
