Abstract
This paper presents the novel imaging technique for localizing the surfaces of solid objects and the liquid freesurface in three-dimensional space. In this method, colour grids, projected from a PC projector, illuminating the surface of object, is recorded by a digital camera to specify the relative relation of the projector and camera coordinates for the grid locations. The shape of the object can be estimated from a pin-hole model for the determined relation. This system was found to be capable of measuring the three-dimensional coordinates of any solid surfaces at high accuracy with mean error less than 0.1 mm through a series of verifications.
