数码相机检校和摄像测量的部分问题探讨

Discussions on the Issues in Calibration of Digital Cameras and Photogrammetry

介绍了数码相机检校的概念 ,阐述数码相机的检校内容和误差来源 ,内方位元素的计算和镜头畸变差校正 ;控制场的建立和影像获取方法 ,直接使用现有摄影测量软件Australis并使检校过程简化 ,指出并分析了实验过程中存在的问题及其原因 .

This paper introduces the conception of calibration of digital cameras,explains the content of calibration of digital cameras and the source of error,studies the method of verifying of digital camera's inner orient elements and the correction of Lens Distortion,and shows foundation of the control field and the method of obtain the images.Use the existing photogrammetric software Australis directly and simplify the course of the calibration.It points out and analyses questions and reasons existing in experiment course.
