MULTI-LENS COPLANAR CALIBRATION SYSTEM AND METHOD

Abstract: a multi-lens coplanar calibration method is applicable to a three-dimensional (3d) imaging device with a plurality of lenses, and the method includes: shooting a reference surface by the 3d imaging device through the plurality of lenses to generate a plurality of 3d images, calculating a plurality of surface equations according to 3d information of the 3d images by a computing device, calculating a plurality of coordinate systems corresponding to the plurality of lenses according to the plurality of surface equations, where one of the plurality of coordinate systems is a first coordinate system, and each of the others is a second coordinate system, calculating a calibration matrix for each second coordinate system relative to the first coordinate system according to at least the plurality of coordinate systems by the computing device, and adjusting based on the calibration matrix by an actuating device.
