Abstract
In project 7-3969, the researchers had successfully developed a new, cheaper high speed texture laser for texture data collection. Based on the project 7-3969, 15 laser based units which are capable of measuring pavement macro-texture at highway speed are delivered in this project.
Compared with the old laser device developed in Project 7-3969, the new version developed in this project has significantly reduced the size, weight, and noise levels, and has improved the standoff distance, measurement range and accuracy.
In this report, the laser triangulation method is briefly reviewed. Then, the improvements over the old laser device and the calibration procedures are also presented.
