So, in the course of photogrammetry job, it is necessary to calibrate the close shot metriccamera, and it is an essential job course to demarcate the digital camera.
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 metriccamera.
The main content of the paper is as follow:(1) camera calibrationUse the single-view calibrating method of vanishing points to calibrate the non-metric digital camera.
