    摘要: Electronic device depth camera systems having a reduced number of outwardly-facing optical components are disclosed. Monocular depth camera systems, including basic depth camera systems as well as RGB-D camera systems, have exactly one window on a housing panel of the device through which light is transmittable out of and into the device housing. An optical emitter and detector(s) are located within the device housing. Binocular RGB-D camera systems have exactly two outwardly-facing optical components on the housing panel. One of the components, such as an optical emitter or an exit window, is associated with illumination light leaving the device, and the other optical component is an entrance window associated with transmitting detection light into the housing.

    摘要: An intra-oral optical scanning method for intra-oral optical scanning including projecting a pattern, the pattern including at least a first area illuminated by a first color of light and a second area illuminated by a second color of light and at least one non-illuminated area onto an intra-oral feature, making a first image of the first area, the second area and the non-illuminated area differentiating between the first color of light and the second color of light in the first image of the projected pattern, and determining from the image of the non-illuminated area at least one of an ambient light level, a level of scattered light, a level of light absorption and a level of light reflected from at least one of the first area and the second area. Related apparatus and methods are also described.
