Abstract

Some elements of comparison are given between the projection-type Moire topography and photogrammetry. The basic mathematics of photogrammetry is applied to reconstruct the 3.D. Shape of the object from the Moire pattern. Some particular aspects of the Moire method are discussed and a general methodology is proposed. In connection with this, an opto-electro nic technique is described, which measures the Moire phase with high resolution and sign determination. The experimental results show that this technique is especially suitable for high accuracy automatic reconstruction of 3.D. Shapes.
