A Method for the Synchronized Acquisition of Cylindrical Range and Color Data

This paper presents a method of 3D human face measurement using a newly developed device that acquires 3D range data and surface color data at the same time. The cylindrical range data is measured by a laser light source and a CCD sensor with a resolution of 5 12 vertical scan lines, 256 points per scan line. The color data is acquired as a cylindrical projection image having 512 by 256 pixels, 24 bitslpixel (8 bits each for red, green, and blue). The scanner has been successfully applied to the measurement of human faces and other 3D objects.
