非量测相机的一种快速平面标定法

A Fast Coplanar Calibration of Non-metric Digital Camera

非量测相机由于其便捷性和价格低的优点受到越来越多的人青睐。平面标定也因为它的制作方便受到越来越多的关注,但是其不稳定性也让很多学者头疼。本文改进了张正友的方法,提高了相机内方位元素初值的精度,从而减少了迭代次数,也使迭代更容易收敛。

Non - metric digital camera is more and more popular with people because of its convenience and cheap charge. People pay more and more attention to coplanar calibration because of its convenience. But, scholars are stumped by its instability. This paper improved the methods of ZHANG Zhengyou, to increase the accuracy of initiation value of interior orientation elements, and to decrease the iterative times for easy of convergence.
