摘要：

Traditional techniques like sand patch method and circular meter provide the reference value for pavement texture inspection. However, these traditional methods can not effectively fulfill the requirement of the highway pavement texture inspection. The non-contact displacement sensor that is able to provide more accurate and reliable results is desirable. The displacement sensor discussed in this paper is specifically designed for highway pavement inspection purpose. This paper mainly discusses the methods adopted by the sensor for eliminating the interference of ambient light and minimizing the error caused by the variation of the target characteristics. In this paper some simulation results and the experiment data were presented.
