Abstract

Moiré topographic technique is widely used for three-dimensional surface reconstruction. One of the main problems is determination of the absolute order of a fringe for finding the depth difference between two points in moiré patterns, i. e. convex and concave surfaces distinction. Most solutions of the problem are very complicated; also they usually require several moiré images. Application of colour-encoded gratings in projection moiré method allows solving the problem simply and quickly. The authors analyze the information that contains in colour moiré fringes and estimate its effectiveness. With this purpose device independent simulations for colour formation of one moiré fringe in colour space by different conditions were made.

Keywords:

surface shape identification, moiré pattern, uniform colour space.
