Paper Abstract

A color-encoded technique for 3D measurement is presented in this paper. In this technique, a color pattern that is composed of RGB components is created by software on a computer screen and projected to an object by a digital light processing, which is controlled by the computer. The image of the object is captured by a CCD color digital camera positioned at an angle different from that of the digital projection system. The color of each pixel of the image has a one-to-one correspondence with the projection angle. The 3D depth map of the object is obtained by way of computer decoding and calculating of the color image captured. This paper mainly introduces the errors analysis and the computer simulation method. The results of the example shows that the relatively errors of the 3D measuring system are smaller than 1%. Simulations have been performed and the results validate the method.
