Paper Abstract

A 3D measuring system on structure light which uses color-encoded technique and digital projection technique to realize 3D measuring is introduced. In this measuring system, a color-encoded pattern that is created by a new method is created by software on a computer and then projected to an object by a digital projection system controlled by the computer. The image of the object is captured by a CCD color digital camera position at an angle different from that of the digital projection system. The color of each pixel determined by the proportion of its primary color, red, green, and blue (RGB) has a one-to-one correspondence with the projection angle. Decoding and calculating for the color image captured, the 3D coordinates of the points on the object surface can be obtained.
