Multi- image Space Resection Based Geometric Calibration for the Four Band CCD Camera
摘要
Abstract
High altitude photographic work such as aerial photogrammetry and UAV photography has very high demands on geometric optical parameters of the CCD camera. As one millimeter or one pixel error of geometric optical parameter tends to cause the error of a few meters or even dozens of meters on the ground, the camera' s high- precision geometric optical parameter calibration is a crucial step for data geometric process after aerial photogrammetry. In this paper, the initial value of inner orientation elements ( the main distance and principal point offset) and the exterior orientation elements (three elements in a straight -line and three angles elements) were acquired by DLT method, and then the single - image space resection and multi - image space resection methods were used to get the geometric optical parameters of the camera. It is concluded that the multi - image space resection is superior to the single -image space resection.关键词
