Abstract: Disclosed is a mobile pavement surface scanning system for detecting pavement distress. In an embodiment the system comprises one or more light sources mounted on the mobile vehicle for illuminating a pavement, one or more stereoscopic image capturing devices mounted on the vehicle for capturing sequential images of an illuminated pavement surface, and a plurality of positioning sensors mounted on the mobile vehicle, the positioning sensors adapted to encode movement of the mobile vehicle and provide a synchronization signal for the sequential images captured by the one or more stereoscopic image capture devices.

Abstract: There is disclosed a mobile pavement surface scanning system and method. In an embodiment, the system comprises one or more light sources mounted on the platform for illuminating a pavement surface, one or more stereoscopic image capturing devices mounted on the platform that capture sequential images of the illuminated pavement surface and a movement sensor that encodes movement of the platform and provides a synchronization signal for time or distance synchronized image capture. One or more processors synchronize the images captured by the image capturing devices and stamps the images with one or more of time and distance data, calculate 3D elevation for each point on the pavement surface using stereoscopic principles, and assesses the quality of the pavement surface to determine the level of pavement surface deterioration.

Abstract: There is disclosed a mobile pavement surface scanning system and method, In an embodiment, the system comprises one or more stereoscopic image capturing devices synchronised with one or more light sources mounted on the platform for illuminating a pavement surface, mounted on a mobile survey platform that provides a trigger mechanism to capture sequential image pairs of the illuminated pavement surface and a movement sensor that continuously measures the movement of the platform and a synchronization signal for time or distance synchronized image capture with accurate GPS positioning. One or more computers process the synchronized images captured stamps the images with one or more of time and distance data, GPS location and calculated 3D elevation for each point on the pavement surface using stereoscopic principles, and assesses the quality of the pavement surface to determine the level of pavement surface deterioration.
