An Image Feature Point Calculation Algorithm Used for Camera Calibration

XIAO Zhi,WU Kai-hua(School of Life Information Science & Instrument Engineering,Hangzhou Dianzi University,Hangzhou Zhejiang 310018,China)  
How to get the coordinates of feature points from the calibration board image rapidly and precisely is one of the crucial steps in camera calibration.According to the calibration issue camera shot from a special space angle,an algorithm used for calculating the coordinates of feature points camera calibration acquired was presented.An area was selected according to the algorithm.And then,some algorithms such as Otsu thresholding,Hit-miss refinement and pixels statistic were executed to get the coordinates of feature points.The result was shown that the algorithm could calculate the coordinate of feature point quickly and effectively and had the advantage of raising the speed and the precision of camera calibration.
