Improvement of measurement method for compact range image sensor using disparity and blur of multi-slit laser

Abstract

In this paper, we propose an improved distance measurement method using blur for 3D measurement. Stereo disparity is often used for 3D measurement, but when a target object is too close to the sensor, it cannot be obtained properly. To solve this problem, we develop a compact range image sensor capable of close-range measurement focusing on the amount of blur using a multi-slit laser and a camera.
