Study on Comparative Analysis of Camera Calibration

Abstract

Several error factors exist when restoring three-dimensional images from two-dimensional images acquired by cameras. In particular, studies that interpret error factors from camera parameters are critical to stereo convergence and three-dimensional image restoration performance. Several error factors exist when restoring three-dimensional images from two-dimensional images acquired by cameras. In particular, in order to interpret the error factors arising from the camera parameters, the camera inspection was performed by applying the methods of calibration of the Tsai camera and the Direct Linear Transformation (DLT) camera calibration using various images entered by the camera. The camera inspection was carried out by applying the method of calibration of the Tsai camera and the method of calibration of the DLT camera. The performance of each camera calibration method was compared by presenting the results of evaluating stereo convergence and restoration performance using camera parameters obtained through camera tests. Modeling techniques for the camera test process were presented through this study. In the future, it is believed that these findings will be used as basic data for image information correction when obtaining image information from the imaging system.
