Know your Kinect, live your Kinect, be your Kinect...
Yeah, okay, a little over the top, but still the more you know about your Kinect and the Kinect for Windows SDK, but better you'll be able to build app's using it. Today we highlight a Kinect for Windows blog post that sheds a little light on the Infrared Control
The Kinect for Windows software development kit (SDK) October release was a pivotal update with a number of key improvements. One important update in this release is how control of infrared (IR) sensing capabilities has been enhanced to create a world of new possibilities for developers.
IR sensing is a core feature of the Kinect sensor, but until this newest release, developers were somewhat restrained in how they could use it. The front of the Kinect for Windows sensor has three openings, each housing a core piece of technology. On the left, there is an IR emitter, which transmits a factory calibrated pattern of dots across the room in which the sensor resides. The middle opening is a color camera. The third is the IR camera, which reads the dot pattern and can help the Kinect for Windows system software sense objects and people along with their skeletal tracking data.
One key improvement in the SDK is the ability to control the IR emitter with a new API, KinectSensor.ForceInfraredEmitterOff. How is this useful? Previously, the sensor's IR emitter was always active when the sensor was active, which can cause depth detection degradation if multiple sensors are observing the same space. The original focus of the SDK had been on single sensor use, but as soon as innovative multi-sensor solutions began emerging, it became a high priority to enable developers to control the IR emitter. “We have been listening closely to the developer community, and expanded IR functionality has been an important request,” notes Adam Smith, Kinect for Windows principal engineering lead. “This opens up a lot of possibilities for Kinect for Windows solutions, and we plan to continue to build on this for future releases.”
