摘要： A video projector device includes a visible light projector to project an image on a surface or object, and a visible light sensor, which can be used to obtain depth data regarding the object using a time-of-flight principle. The sensor can be a charge-coupled device which obtains color images as well as obtaining depth data. The projected light can be provided in successive frames. A frame can include a gated sub-frame of pulsed light followed by continuous light, while the sensor is gated, to obtain time of flight data, an ungated sub-frame of pulsed light followed by continuous light, while the sensor is ungated, to obtain reflectivity data and a background sub-frame of no light followed by continuous light, while the sensor is gated, to determine a level of background light. A color sub-frame projects continuous light, while the sensor is active.

摘要： A depth-mapping method comprises exposing first and second detectors oriented along different optical axes to light dispersed from a scene, and furnishing an output responsive to a depth coordinate of a locus of the scene. The output increases with an increasing first amount of light received by the first detector during a first period, and decreases with an increasing second amount of light received by the second detector during a second period different than the first.

摘要： A system for controlling infrared (IR) enabled devices by projecting coded IR pulses from an active illumination depth camera is described. In some embodiments, a gesture recognition system includes an active illumination depth camera such as a depth camera that utilizes time-of-flight (TOF) or structured light techniques for obtaining depth information. The gesture recognition system may detect the performance of a particular gesture associated with a particular electronic device, determine a set of device instructions in response to detecting the particular gesture, and transmit the set of device instructions to the particular electronic device utilizing coded IR pulses. The coded IR pulses may imitate the IR pulses associated with a remote control protocol. In some cases, the coded IR pulses transmitted may also be used by the active illumination depth camera for determining depth information.

摘要： Systems and methods for increasing the resolution of a depth map by identifying and updating false depth pixels are described. In some embodiments, a depth pixel of the depth map is initially assigned a confidence value based on curvature values and localized contrast information. The curvature values may be generated by applying a Laplacian filter or other edge detection filter to the depth pixel and its neighboring pixels. The localized contrast information may be generated by determining a difference between the maximum and minimum depth values associated with the depth pixel and its neighboring pixels. A false depth pixel may be identified by comparing a confidence value associated with the false depth pixel with a particular threshold. The false depth pixel may be updated by assigning a new depth value based on an extrapolation of depth values associated with neighboring pixel locations.
