Claim One:
1. A system comprising: at least one processor; and memory storing instructions that, when executed by the at least one processor, cause the at least one processor to perform acts comprising: receiving an infrared image of a scene irradiated by an infrared emitter, the infrared image captured by an infrared camera, the infrared image comprises pixels, each pixel in the pixels having an intensity value assigned thereto; generating a depth image of the scene based upon the infrared image of the scene, wherein the depth image comprises depth pixels, each depth pixel having a depth value assigned thereto that is indicative of a distance between the infrared emitter and a respective object in the scene, wherein generating the depth image of the scene comprises applying the principle of light falloff with respect to intensity values of the pixels of the infrared image to compute the depth values of the depth image, and further wherein when the principle of light falloff is applied to an intensity value of a pixel in the infrared image, a depth value of a corresponding depth pixel in the depth image is computed by the at least one processor based upon a square root of the intensity value of the pixel in the infrared image; and rendering graphical data on a display based upon the depth image.
