一种基于棋盘格模板单目摄像机高精度标定方法
Monocular Camera High Precision Calibration Method Based on Checkerboard
摘要
Abstract
In this paper, a monocular camera calibration method based on checkerboard template is presented.This method is using a high-precision CCD camera to take pictures of checkerboard calibra-tion template which is placed on a two-dimensional platform with hand-operated rails.Its fixed values vary along the Z axis, and so the subpixel coordinates of checkerboard corner points yield.Then all the camera parameters can be obtained by adopting DLT calibration method, and finally the arbitrary checkerboard corner points will be reconstructed to test the accuracy of calibration by estimating in 3 D spatial coordinate.The average error of horizontal and vertical coordinates are both ±0.02 mm.Ex-perimental data show that by using this method high-precision camera parameters can be obtained quick-ly and efficiently, which meets the requirements of three-dimensional reconstruction and other visual in-spection occasions.关键词
