- pavlov 14y agoThe Kinect is a bit different. It has one regular camera, one infrared camera and an infrared projector. It projects a random-looking pattern which is seen by the camera and analyzed by the unit's firmware. The pattern's perspective and scale distortions are mapped into depth coordinates (perhaps aided by the visible light camera image). The device then outputs RGB+depth images via USB with a maximum frame rate of 60 fps. The Leap doesn't have an infrared projector that could emit a precise pattern, but it has two infrared cameras that run at a much higher rate than the Kinect's. I think the Leap's depth detection is based primarily on stereo vision mapping with some kind of temporal component.
- pfraze 14y agoAh, interesting. Thanks.
