Abstract

Application of photogrammetry in industrial environments requires full automation capable of functioning without human supervision. The main elements in such systems are the high resolution of cameras, the strength and durability of cameras in terms of their geometric shape and structure and the frequency of their response. In this regard, a series of modern cameras have been designed that provide both 2000 × 3000 and 70000 × 40000 sensors and so remove the usual obstacles that preclude the acquisition of precision and show great potential for high precision metrological 3D images.

The high efficiency and features of the 3D metrology system have made it possible for the few but highly skilled producers to find a place in the global market. Most of these systems can be characterized by the following features:
 Specific objectives (reflective targets, light emitting diodes (LEDs), high contrast object characteristics, points and patterns image, etc. that are used to produce signals representing the desired points in order to achieve optimal contrast.
