Photogrammetric analyser for industrial photogrammetry - has photographs of object placed on plate of stereo comparator

摘要

Reference points are measured and quantities defining the photograph reference points calculated. Points necessary for determination of the relation between object reference points and the photograph reference points and the realtions are calculated. The system functioning is defined in a curve simulator, corresponding information is fed into the equipment, and movement of marking points w.r.t. the observed stereoscopic model is controlled by potentiometers in a control desk. Coordinates of corresponding points in the reference object are calculated by a computer which controls the movement of photograph supporting plates in the analyser. The last three process steps are repeated as long s necessry, and coordinates of measured points are recorded when the mark coincides with the object.
