Recording a video from a depth sensor

Finally, after all these preparations completed, you are ready for performance.

It is convenient to put MS Kinect Sensor on a chair or a table. The picture below will help you to understand possible capture area and required space:

Side view	Top view

Please start iPi Recorder and choose “MS Kinect Sensor (OpenNI)” in Camera Selector dialog:

Using “Motor” slider, adjust direction of sensor so that you can see floor at the bottom and actor is fully visible (with hands up if needed):

Set output directory for recorded video:

Press “Start Video Recording” button to begin video recording.

Important! Initial two seconds of video should contain only background and static objects. Presence of actor or any moving objects in the initial two seconds of recorded video is unacceptable. It’s because initial seconds of video are used to calculate static background necessary to separate actor from other objects of 3D scene.

As soon as recorder starts and “clear” scene is recorded for a couple of seconds, go to the capture area and stand in a T-pose:

Note that current version uses only depth information to track motions. So there are no restrictions on clothes colors (just avoid shiny fabrics). Please use slim clothes to reduce noise in resulted animation.

After that you can act desired motions.

To stop recording, press “Stop Video Recording” button.

Using Windows Explorer, go to destination folder and open the recorded file with name video_YYYY-MM-DD_hh-mm-ss.avi in Windows Media Player. You should see depth information as a blue image:

Now you are ready for processing this video using iPi Studio.
