Abstract
The purpose of the present invention is to provide a shape measuring device and method, wherein the separation of light from one distance sensor increases measurement precision without increasing the size of the device. The present invention provides 'a shape measuring device comprising: a distance sensor that radiates a laser toward a measurement target and detects the reflected light so as to calculate the distance to a measurement point; a separation unit that separates the light from the distance sensor into a plurality of light rays; a rotation unit that rotates the distance sensor and the measurement target relative to each other; and a data processing unit that integrates measurement results obtained from the distance sensor for the distances to a plurality of measurement points.'
