Megha Simlote, Pratibha Agrawal, Sunil Pathak . Repeatable Extrinsic Stereo Camera Calibration by Moving Chessboard in a Straight-line. International Journal of Computer Applications. 178, 52 ( Sep 2019), 1-4. DOI=10.5120/ijca2019919377
Abstract
Camera calibration is the procedure of identifying camera parameters for rectifying and un-distorting the images. In this paper Calibration of Stereo Camera using the set of images taken by 2 cameras (from left and right direction) and study about the stability as well as statically analysis of parameters is carried out by physically changes the angle of camera. For estimating extrinsic parameters the images could be taken in a way, covering whole surface area of the camera sensor i.e. at different depth and orientation but later, it was observed that if the images taken were in a straight line at different depths covering the same area of camera sensor then the repeatability could be seen in the results of extrinsic parameters.
