A Facial Measurement System for 3-D Shape with Color Texture

Abstract

A rangefinder system which measures both the 3-D shape and color texture of a human face is described. In our system, high-speed face measurement is achieved by using a space-encoding method with laser scanning. This system equips a color CCD camera as an image input device which grabs both range and color texture images. There is the possibility that laser radiation is harmful to human eyes and our system meets the Japanese radiation safety standards for laser products. In our experiment, this system obtained 3-D shape and color texture information in about 2 seconds. The measurement error on shape was found to be less than 1 mm.
