So, in the course of photogrammetry job, it is necessary to calibrate the close shot metric camera, and it is an essential job course to demarcate the digital camera.

因此，在摄影测量的作业过程中，有必要对近景摄影机进行检校，对数码相机的标定是一项必不可少的作业过程。

Ordinary digital camera has its own advantages in obtaining digital images, but its data processing needs a special method because the digital camera belongs to non metric camera.

用普通数码相机获取数字影像具有一定的优势，但由于普通数码相机是一种非量测相机，其数据处理需要特殊方法。
