Paper Abstract

The developed measuring device is a noncontacting system utilizing a He-Ne laser, which permits rapid measurement of interior dimensions of automobiles, based on the principle of optical triangulation. Laser beam is projected from the head of the device to a point to be measured as a spot and this spot is automatically searched by means of a mirror, a lens and a two-element photodetector to measure the length along the projection axis. The head of the device including optical parts is rotated by a motor and the rotating angle is measured by a rotary encoder. Thus, the measured length and rotating angle are calculated into rectangular coordinate values with a microcomputer, and the coordinate values can be represented on a panel and also punched out on a teletypewriter. The values thus obtained with this device have been successfully utilized for a computer aided design system for automobiles.
