Computer Aided Color-encoded Moiré Contouring

Moire topography technique is widely used for automatic inspection systems and machine vision. The problem common for all Moire methods is extraction information about surface ambiguities. Many solutions were worked up to solve the hill and valley problem. Mostly proposed methods required moving hardware and/or complicated analyzing process. In this paper we present a new computer aided color-encoded Moire contouring technique, that simple, cheap and quickly solves the problem of ambiguities in Moire patterns. Our method is based on application of color-encoded gratings
