Abstract

Since the Semmes-Weinstein aesthesiometory is mainly the work by hands, the long inspection time is needed and the quantitativity is not high. We proposed the new diagnostic support system which applied mechatronics and image measurement in order to solve the problem. In this paper, the composition of the system is explained. And, the measurement principle of the 3-D sensor which is a part of the system is explained. The 3-D shape in mandible is calculated by the 3-D sensor, and the movement control of the Semmes-Weinstein aesthesiometer is carried out based on the shape information. The sensor is composed of the CCD camera and the LED projector, and the 3-D shape is calculated based on the triangulation. In addition, it is shown that the 3-D shape in the mandible can be calculated actually.
