A Simple Camera Calibrating Method Based on Local linearization Technology

A camera calibrating method based on local linearization technology is proposed to resolve the existing problems with calibration of 2-D image measuring system. A regression matrix is used to describe the linear camera model, which makes the computation course simply greatly, avoids computing the redundant parameters. Images are divided to pieces and in each piece a specific H is used to improve precision. Theoretical analysis and experimental results show this method is easy and accurate and has strong practicality.
