Method for reconstructing three-dimensional objects used in quality control application, involves generating gray value profiles from subset of pattern image sequence and subset of surface of object shifted fringe patterns

摘要

The method involves projecting stripe pattern in the phase surface of the object (1). Each of the surface with the superimposed pattern is detected by a camera (4,5). The gray level gradients in the recorded images pixel correspondence between associated pixels are determined. The gray value profiles are generated from a subset of the pattern image sequence and subset of the surface of the object shifted fringe patterns.
