1. A method for dynamic image processing, comprising the following steps: a) acquiring real image data through a first sensor and real depth data through a second sensor from a real scene, the real image data and the real depth data being matched one to another; b) processing the real depth data to extract real normal vector data; c) generating and running a virtual model from which there can be extracted, at least, virtual image, virtual depth data and virtual normal vector data; d) processing occlusions in a physics engine using the real image, the virtual image, the virtual depth data and a continuous mesh generated from the real depth data; e) processing lighting using the real depth data, the real normal vector data, the virtual depth data and the virtual normal vector data; and f) outputting the real image and the virtual image, subjected to the occlusions and the lighting, to a display.
