Computer Vision Calibration New Easy Method

In order to make the calibration convenient, this paper proposed a new easy calibrating target plane. This method based on circular point theory. The target plane consists of a triangle and some lines. We take photos of the target from different position, and then calculate the circular points by Laugerre theory. The intrinsic and extrinsic parameters can be determined. This method is simple and based on linear units. That would improve the accuracy by fitting those units against noise error. The more important thing is that the method could avoid regression phenomena. Simulated data and real experiments show that the new technique is robust and accurate.
