Patent Images
1. A texture projecting light bulb comprising:
- an incandescent filament configured to produce infrared light;
an integrating sphere enclosing the incandescent filament, wherein the integrating sphere comprises a diffusely reflective interior surface, a baffle disposed at least partially within the integrating sphere, and an aperture configured to allow light to pass out of the integrating sphere; and
a light bulb enclosure surrounding the integrating sphere, the enclosure comprising one or more regions transmissive to infrared light and one or more regions opaque to infrared light, wherein the one or more transmissive regions are configured to project a structured light pattern of infrared light detectable by a computer vision system.

Abstract
A texture projecting light bulb includes an extended light source located within an integrator. The integrator includes at least one aperture configured to allow light to travel out of the interior of the integrator. In various embodiments, the interior of the integrator may be a diffusely reflective surface and the integrator may be configured to produce a uniform light distribution at the aperture to approximate a point source. The integrator may be surrounded by a light bulb enclosure. In various embodiments, the light bulb enclosure may include transparent and opaque regions configured to project a structured pattern of visible and/or infrared light.
