The Measurement of Three-Dimensional Road Roughness Based on Laser Triangulation


Article Preview

This article did some non-contact measurement by laser triangulation principle on the A level hard road roughness, based on CCD imaging principle,used scanning galvanometer, which improved the measurement speed and surface measurement range, , drew the three-dimensional surface roughness profile curve by interpolation and fitting,It was in accordance with the standard range of A-road height spectrum. This measurement method have important guiding significance on the hard road roughness measurement and practice of the design of the relatively flat three-dimensional contours.
