| 摘 要： | 基于平面模板的相机检校方法是一种简便、实用的检校方法,但需要一个平面模板,这在某些应用场合难以满足.本文采用在同一平面内布设一定数量的人工标志点的方法代替平面模板,用常规量测工具精确测量标志点间的平面距离,采用自由网平差得到模型坐标,然后根据经典平面检校方法得到检校参数.实际图像数据实验结果表明,在布设少量标志点的情况... |

| Abstract: | Camera calibration based on planar pattern is a flexible and applicable approach,and has been widely used in many fields,while it needs a planar pattern,which is hard to be placed in some industrial measurement cases,so the on-situ calibration cannot be realized.This paper uses a set of discrete artificial targets located on a plane instead of planar pattern.The distances among these targets are accurately measured and the fee network adjustment is used for getting their accurate coordinates,then the calibr... |
