US Patent 9715008 Visualization of 3-D GPR data in augmented reality

In one embodiment, an augmented reality application generates an augmented reality view that displays three-dimensional (3-D) ground penetrating radar (GPR) data on boundary surfaces of a virtual excavation. The augmented reality application calculates an intersection of the one or more boundary surfaces of the virtual excavation and the 3-D GPR data, and extracts data items of the 3-D GPR data that intersect the one or more boundary surfaces of the virtual excavation. The augmented reality application then projects two-dimensional (2-D) images based on the extracted data items onto the one or more boundary surfaces of the virtual excavation to show subsurface features in the augmented reality view that can be manipulated (e.g., moved, rotated, scaled, have its depth changed, etc) by a user.
