The camera calibration apparatus and method, image processing apparatus and method, a program providing medium, and the camera

摘要

The present invention relates to a high-performance camera calibration apparatus and method capable of accomplishing stable high-accuracy parameter estimation. A pattern whose geometrical configuration is known in advance is photographed by a camera to generate a picked-up image, with the generated picked-up image being temporarily stored as an image input in a frame buffer. In addition, a base image having a pattern univocally corresponding in geometrical configuration definition to the picked-up image is generated according to the CG technology or the like, and is stored in another frame buffer. An image registration is made between the base image and the picked-up image to minimize the luminance error, which enables the parameter estimation.
