A system for measuring surface deflection of a road includes a first stereo line-scan camera pair on a sensor rig and for capturing a first set of 3D images of a road surface; a second stereo line-scan camera pair on the sensor rig and for capturing a second set of 3D images of the road surface; at least one digital electro-optical (EO) camera rigidly attached to the sensor rig; an inertial measurement unit (IMU) detecting inertial forces acting upon the sensor rig; and a processor compensating for acceleration and vibration effects upon the sensor rig; and calculating the surface deflection of the road based on the first and second sets of 3D images. The processor utilizes imagery from the EO camera and inertial measurements from the IMU to produce 2D mosaics and 3D reconstructions of the road surface from the first and second sets of 3D images.
