Research on Laser Measuring Instrument for Tunnel Surfaces

Abstract

Abstract:

A laser instrument was designed to measure tunnel surfaces, which used a laser distance measurement component as measuring sensor. The tunnel surface shape and the outline of the object can be measured by the instrument, which can rotate around two mutually perpendicular axes. The measured data was processed and the graphic of the surface shape was generated. The hardware structure and composition of the instrument were analyzed, the hardware circuit was designed and components were chosen. Hardware control software and data processing procedure were designed. An actual surface can be measured to draw out the 3D graphics. The advantages of this instrument were verified that has stable performance, quick measurement and convenient to use in practices.
