Measurement of 3D Space Using a 2D Profilograph

Abstract

This article proposes a method how to create a measurement system which can be used as a terrestrial laser scanner. The system utilizes laser scanner LD-OEM 1000. It measures profiles therefore it is capable to capture an area 360 degrees around itself at the width of one laser impulse. Our method of the terrestrial scanning benefits from the fact that the measured profiles are in vertical plane and the rotation of the whole scanner allows us to create complete 3D model of the surrounding space. The article explains design of the controlling software and mechanical construction used for desired rotational motion of the whole scanner. Proposed method has been tested on real hardware and the achieved results are presented at the end of the article.
