The Test on Bridge Deflection Deformation Monitoring by Terrestrial Laser Scanning
Abstract This paper examines bridge deflection measurement. Against the characteristics of the point cloud at the bottom surface of the bridge, two methods: fitting calculation and center of gravity calculation,are used to obtain the deflection change of the bridge under different loadings. The results are compared and analyzed and the preliminary measuring precision of this technology is confirmed. Theexperiment also verifies the feasibility of this technology in bridge deflection measurement.
Key words :
