This paper describes a 3-D automated pavement distress data collection and analysis system based on NRC's Biris sensor technology. The paper introduces the problem to be solved, the selected design criteria, and the adopted solution to monitor the quality of road surfaces. The system geometry for the acquisition of the three-dimensional coordinates of pavement surface distresses is presented. Multiple feature extraction and system integration concepts are given with emphasis placed on the real-time processing of the raw data by a parallel array of processors. Advantages and disadvantages of this technology are discussed. System performances and experimental results are provided.
