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.

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. One or more computer processors are adapted to synchronize the intensity image pairs captured by each camera in the one or more stereoscopic image capturing devices, perform a 3D reconstruction of the pavement from the intensity image pairs using stereoscopic principles, generate a depth image and an intensity image pair from the 3D reconstruction, and process at least one of the depth image and the intensity image utilizing one or more distress detection modules to detect a type of pavement distress.
