Triangulation measurement device for determining object 3D structure has illumination and observation arrays with a projected pattern being evaluated using cross correlation or phase shift analysis

摘要

Triangulation measurement method for 3D measurement of the structure and position of objects with illumination and observation beams. At least transmission pattern array and a receiving array are used, with the pattern generated on an object evaluated using cross-correlation or phase shift evaluation. Independent claims are also included for the following:- (a) a sensor for the highly precise optical scanning of objects to determine their 3D structure and; (b) a further triangulation 3D structure measurement method.
