Arrangement for object photogrammetric measurement - has sensors and camera with positioning no adversely affected by reference pattern image formation

摘要

The arrangement contains two individually positionable optical sensors (5-7), associated projection centres in defined relative spatial positions and an optical reference pattern (14) on the object space side. The reference pattern is placed outside the imaging beam path (11-13) between the object and the sensors. Optical deflectors (15-17) in defined positions wrt. the sensors form images of the reference pattern. USE/ADVANTAGE - Positioning wrt. object of sensors and cameras contg. projection centres is not adversely affected by reference pattern image formation.
