Auto-Location of Planar Checkerboard Pattern Image Corners

WANG Zhong-shi~1,Han Xiao-wei~2,XU Xin-he~1(1.School of Information Science & Engineering,Northeastern University,Shenyang 110004,China;2.School of Information Engineering,Shenyang University,Shenyang 110044,China.  
The location of the internal corners of a planar checkerboard pattern image is very important to camera calibration.An effective approach is proposed to automatically locate the internal target corners of a planar checkerboard pattern image,based on the characteristics of the vanishing point,the grid line architecture and the local gradation.Experimental results showed that the approach can obviously save the time required for camera calibration and speed up the calibration process.Especially,it is adapted to the automatic multi-image calibration.
