IMAGE CAPTURE DEVICE WITH A CALIBRATION FUNCTION AND CALIBRATION METHOD OF AN IMAGE CAPTURE DEVICE

摘要

An image capture device includes at least one image capture unit and a calibration unit. A calibration method of the image capture device includes an image capture unit of the at least one image capture unit capturing a first image, the calibration unit executing a global calibration operation on original coordinates of all image points of the first image to generate first rectification coordinates of the all image points, the calibration unit finding a geometric graph including each image point of at least one image point of the all image points according to first rectification coordinates of the each image point of the at least one image point of the all image points, and the calibration unit rectifying the first rectification coordinates of the each image point to second rectification coordinates of the each image point according to a rectification equation corresponding to the geometric graph.
