摘要	The photogrammetry technique is widely used for measuring 3-D shape in diverse industries thanks to its easy implementation and straightforward algorithm. However, most measurements done by this technique are using a single camera with multi-exposure and the results are derived after a period of time. Along with the development of the CCD and computer technology, it is now possible to use multi-camera, real-time photogrammetric measurements and the results could be derived without much time delay. A multi-camera system avoids the error caused by time-delayed exposure. So the new technique could be widely used in telescope surface or position measurement and control. In thispaper, the pertinent formulations, implementation and application details are discussed before a general conclusion is drawn.
