| Research Abstract |
Grating Projection Method is a simple, compact, and low-cost method to measure a surface shape in a short period of time. A regularly sinusoidal light-dark stripe is projected from a PC projector, and the phase angle of the distorted stripe on an object surface is computed by a PC using the photographic image of a digital camera. Often used structural materials in space, such as transparent metal mesh, polymer film, and metalized polymer film, were thought to be ill-suited to the optical principle. The method developed here is shown to be suited to measure these materials, too. An interpolative method to compute the coordinate value of the surface framed in by two reference planes is extended to extrapolative range in order to measure a large space structures.
