Pavement Inspection Robot

A pavement survey is a time-consuming but necessary task to ensure the serviceability of road pavements. We developed a pavement inspection robot (PI-bot) to automate the pavement inspection in the project level. PI-bot is capable of inspecting the pavement condition using a camera and artificial lights. It can capture and analyze the images in the real-time to identify the possible distresses on the pavement surface. The motion system can be controlled according to the results of real-time analysis. PI-bot is implemented by using Microsoft Robotics Developer Studio, which ensures the flexibility and extensibility of the system. Many investigators have used image-processing methods to automate the survey processes and enhance the quality and accuracy of survey results. However, image-processing methods often mistakenly treat oil spillages, shadows, and road markings as distresses since their features are very close to the ones of distresses. To solve the problems we use dual light to do the inspection. This method makes our PI-Bot fully complete.
