Acquiring Image and Skeletal Data Using Kinect

In “Detecting the Kinect Devices” on page 12-7, you could see that the two sensors on the

Kinect for Windows are represented by two device IDs, one for the color sensor and one of

the depth sensor. In that example, Device 1 is the color sensor and Device 2 is the depth

sensor. This example shows how to create a videoinput object for the color sensor to

acquire RGB images and then for the depth sensor to acquire skeletal data.

Create the videoinput object for the color sensor. DeviceID 1 is used for the color

sensor.

vid = videoinput('kinect',1,'RGB_640x480');

Look at the device-specific properties on the source device, which is the color sensor

on the Kinect camera.

src = getselectedsource(vid);
