Multi Laser Displacement Sensors Based Three-dimensional Pavement Measuring Technology

摘要

A three-dimensional measuring method for pavement based on multi laser displacement sensors is proposed to establish a complete and powerful database of pavement shape. Model of the measuring system based on this method is established and analyzed. Data generated by sensors, including data of laser displacement sensors, acceleration sensors and gyroscope, is transmitted according to TCP/IP Protocol. The back-end computer fuses the data and establishes the databank of 3-D pavement shape. Experimental results of pavement shape measurement using gradienter and the system based on this method proved that the application and accuracy of this method are satisfied.
