Camera calibration for stereoscopic technique

Camera calibration is becoming a latest topic in recent years because of its flexibility. In this work a close range stereoscopic technique is used to calibrate stereoscopic camera. The camera calibration is estimated the those parameters. It is an indispensable step for medical photogrammetric or image guided applications. The quantitative information should derive from the images. Non linear optimization are widely used in camera calibration in order to the intrinsic and extrinsic parameters. The traditional optimization algorithm have such problem as being prone to get into local extreme and being susceptive to initial value in calibration. By calibrating the camera it could be used for accurate measurement. The aim of the method stereovision technique is used to capture the two images. Tilt the input image angle shifted in o to 60 degree. Thus the input image is applied to the anaglyph method to calculate the accurate measurement.
