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.
