Abstract

This paper presents a novel image measurement technique to measure three-dimensional shapes of solid objects and liquid free-surfaces. In this technique, three-dimensional locations of the surface, where color grids are illuminated by a PC projector, can be estimated from recorded digital images of the grids reflected on the surface. This imaging technique was found to be capable of measuring the three-dimensional coordinates of solid surfaces at high accuracy with mean error less than 0.1 mm through experimental tests. Complex shapes of a breakwater composed of armor block models and of water wave surfaces have been reasonably measured in this technique.
