OBJECT POSITION MEASUREMENT TECHNIQUE

摘要

FIELD: measurement technology for computer-aided process control systems. SUBSTANCE: at least one light-emitting mark is placed on object surface and spatial coordinates of this mark are determined by location of its image on coordinate-sensing photodetector of optical camera. Used as light-emitting mark is light emitter whose phase and frequency are in synchronism with starting moment of optical-camera photodetector. EFFECT: improved reliability and confidence of measurement results. 1 dwg
