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： Compatibility between a depth image consumer and a depth image producer is provided by receiving a native depth image having an unsupported type that is not supported by a depth image consumer, and processing the native depth image into an emulation depth image having a supported type that is supported by the depth image consumer. This emulation depth image is then output to the depth image consumer.

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： Techniques are provided for determining depth to objects. A depth image may be determined based on two light intensity images. This technique may compensate for differences in reflectivity of objects in the field of view. However, there may be some misalignment between pixels in the two light intensity images. An iterative process may be used to relax a requirement for an exact match between the light intensity images. The iterative process may involve modifying one of the light intensity images based on a smoothed version of a depth image that is generated from the two light intensity images. Then, new values may be determined for the depth image based on the modified image and the other light intensity image. Thus, pixel misalignment between the two light intensity images may be compensated.

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.
