AN INSPECTION OF PROPERTIES EQUIP MMS WITH PHASE DIFFERENTIAL LASERSCANNER MEASUREMENT MATERIAL TYPES

Abstract

 In this study, we analyzed and verified the acquired point cloud when the material of the target surface was different during measurement by MMS equipped with a phase difference laser scanner. As a result, the point clouds were plotted in the place different from the targets installation position for targets with strong reflection intensity, and noise was likely to occur and the shape of the point cloud was disturbed and the number of acquired points was reduced in the target with weak reflection intensity.
