Journal ArticleDOI
Precise calibration of binocular vision system used for vision measurement
TL;DR: A precise calibration method is proposed for binocular vision system which is devoted to minimizing the metric distance error between the reconstructed point through optimal triangulation and the ground truth in 3D measurement coordinate system.
Journal ArticleDOI
A novel optimization method of camera parameters used for vision measurement
TL;DR: The results show that the proposed 3D optimization method is quite efficient to improve measurement accuracy compared with traditional method and can meet the practical requirement of high precision in 3D vision metrology engineering.
Journal ArticleDOI
A novel laser vision sensor for omnidirectional 3D measurement
TL;DR: A novel omnidirectional laser vision sensor is developed by adopting plane mirrors instead of curved mirrors so that the simple traditional camera model can still be used, and the measurement accuracy can be maintained at the same level with the traditional structured-light vision.
Journal ArticleDOI
Line-based camera calibration with lens distortion correction from a single image
TL;DR: Results show that the proposed line-based camera calibration method with lens distortion correction from a single image using three squares with unknown length is robust under general conditions and it achieves comparable measurement accuracy in contrast with the traditional multiple view based calibration method using 2D chessboard target.
Journal ArticleDOI
Accurate and robust estimation of camera parameters using RANSAC
TL;DR: Results show that the proposed accurate and robust estimation method for camera parameters based on RANSAC algorithm is robust under large noise condition and quite efficient to improve the calibration accuracy compared with the original state.
