A non-contact, rapid, and automatic system for three dimensional measurement of the human face by utilizing a new optical cutting method was developed. The system includes: 1.The multi-slit laser array was devised to minimize the scanning time, while the accumulating optical cutting image technique was to reduce the memory size. 2.The illumination intensity center of each slitrimage was detected to generate the space coordinates;moreover, quadratic form was applied to correct coordinate values. With this system, the whole face can be recorded within six seconds and reconstruct a 3-D image in approximately four minutes.The accuracy of this apparatus was confirmed to be within 0.4% error for the view of 250mm in height and 200mm width. From these results, this system is considered useful in clinical human face measurement.
