Abstract
A range camera operable to provide a range image of a scene and a picture of the scene, based on non-visible light and visible light registered for features in the scene on a same photosensor.
Claims20
A range camera operable to provide a range image of a scene and a picture of the scene, the range camera comprising:
- a light source operable to transmit non-visible (NV) light to illuminate the scene;
- a photosensor having a plurality of NV pixels configured to register NV light reflected by features in the scene from the transmitted NV light, and a plurality of picture pixels configured to register visible light reflected by the features;
- and
- a controller configured to:
- determine pictures of features in the scene imaged on the picture pixels based on the visible light that the picture pixels register:
- assign intensities of visible light to each of the plurality of NV pixels based on the NV light registered by the NV pixel and the visible light registered by a picture pixel of the plurality of picture pixels;
- and
- provide a picture of the scene based on the visible light registered by the picture pixels and the intensities of visible light assigned to the NV pixels.

A method of providing a range image and a picture of a scene, the method comprising:
- transmitting non-visible (NV) light to illuminate the scene;
- registering light from features in the scene on a photosensor having a plurality of NV pixels configured to register NV light reflected by the features from the transmitted NV light, and a plurality of picture pixels configured to register visible light reflected by the features;
- determining distances to features in the scene imaged on NV pixels based on the NV light registered by the NV pixels;
- determining pictures of features in the scene imaged on the picture pixels based on visible light that the picture pixels register:
- assigning intensities of visible light to each of the plurality of NV pixels based on the NV light registered by the NV pixel and the visible light registered by a picture pixel of the plurality of picture pixels;
- and
- providing a picture of the scene based on the visible light registered by the picture pixels and the intensities of visible light assigned to the NV pixels.
