随着大面阵CCD技术以及数码相机的出现、应用和发展,数码相机开始应用于摄影测量生产,但是数码相机镜头畸变差很大,内方位元素无法直接量取,属于非量测型相机,这就使得数码相机无法直接在摄影测量中使用。文章通过对数码相机的检校和精度分析,说明了数码相机通过检校具有较高精度,并通过具体实践,证明了经检校的数码相机用于摄影测量是可行的。
With the advent,appearance,application and progressing of CCD and digital-camera technology,digital-camera is being applied in photogrammetric production.But digital-camera also has some shortcommings,such as the aberrances of digital camera lens is worse normally,and it' sinterior orientations cant be measured directly,so it's difficult to use digital camera to take aerial im- age,because digital camera is"non-measured"camera.so we can't use digital-camera for photogrammetric directly.In this paper, we cal...
