Synchronized acquisition of three-dimensional range and color data and its applications

This paper presents a method of acquiring three-dimensional human face data using a newly developed device that acquires three-dimensional range data and surface color data at the same time. Cylindrical range data is measured by a laser light source and a CCD sensor with a resolution of 512 vertical scanlines, and 256 points per scanline. The color data is acquired as a cylindrical projection image having 512 by 256 pixels, 24 bits/pixel (8 bits each for red, green, and blue). The scanner has been successfully applied to the scanning of human faces and other three-dimensional objects. This paper also details various applications using the scanner.
