Abstract

A mobile (truck-mounted) imaging system uses laser-based technology to obtain accurate quantitative data in real time and at high speeds regarding the conditions of road and highway surfaces. Specifically, the GIE Technologies laser vision system integrates a three-dimensional laser-sensing imaging sensor array to map the cracks, ruts and roughness of road surfaces. The LaserVision System simultaneously records a three-dimensional information along with photometric data using the same set of Biris (bi-iris) sensors. These sensors were developed for this application by engineers at GIE Technologies Inc. under exclusive license from the National Research Council (Ottawa, Canada). They rely on a combination of defocusing and triangulation principles to record 3D information about a test surface. The Biris approach, for a mobile pavement testing system, offers several performance advantages in comparison to other sensing methods. Most important, a Biris sensor uses all- solid-state components with no moving parts. This rugged design is highly resistant to misalignment and performs well in a moving, continuously vibrating vehicle. The photometric (intensity) information provides complementary data where ranging alone proves insufficient, as when detecting pavement markings, sealed road cracks or patches. In addition, the range analysis uses simple trigonometry to obtain real-time performance.
