A target-orientated navigation system and related method for a vehicle having a generic navigation system includes one or more processors and a memory. The memory includes one or more modules that cause the processor to receive perception data, discretize the perception data into a plurality of lattices, generate a collision probability array having a plurality of cells that correspond to the plurality of lattices, determine which cells of the collision probability array satisfy a safety criteria, receive an artificial potential field array having a plurality of cells that correspond to the plurality of cells of the collision probability array, generate, an objective score array having a plurality of cells corresponding to the cells of the collision probability array, and direct a vehicle control system of the vehicle to guide the vehicle to a location representative of a cell in the objective score array that has a highest value.

An artificial intelligence system for an autonomous vehicle includes one or more processors and a memory in communication with the one or more processors and storing a target-orientated navigation system module. When executed, the target-orientated navigation system module causes the one or more processors to receive sensor data from one or more sensors of a vehicle, synchronize the sensor data, preprocess the synchronized sensor data by transforming the sensor data into a common data format, concatenate the transformed sensor data into a K-dimensional array, which acts as an input state array, apply a navigation policy to the input state array to estimate an action-value array, direct a vehicle control system to guide the vehicle to a location representative of a cell in the action-value array that has a highest reward value.

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.
