Abstract

A calibration method of an image capture system includes an image capture device of at least one image capture device capturing an image including a plurality of intersection coordinates among a plurality of geometric blocks of a test pattern and an information of a color of each geometric block of the plurality of geometric blocks; an operation unit executing a first operation on the plurality of intersection coordinates within the image to generate a plurality of geometric calibration parameters; the operation unit executing a second operation on an information of a color of each geometric block of the plurality of geometric blocks within the image to generate a plurality of color calibration parameters; and a calibration unit calibrating the image capture device according to the plurality of geometric calibration parameters and the plurality of color calibration parameters.
