Detect the Kinect V1 Devices

Typically, each camera or image device in the Image Acquisition Toolbox™ has one DeviceID. Because the Kinect® for Windows® camera has two separate sensors, the color sensor and the depth sensor, the toolbox lists two DeviceIDs. Use imaqhwinfo on the adaptor to display the two device IDs.

info = imaqhwinfo('kinect');
info

info = 
 
       AdaptorDllName: '<matlabroot>\toolbox\imaq\imaqadaptors\win64\mwkinectimaq.dll'
    AdaptorDllVersion: '4.6 (R2013b)'
          AdaptorName: 'kinect'
            DeviceIDs: {[1]  [2]}
           DeviceInfo: [1x2 struct]

If you look at each device, you can see that they represent the color sensor and the depth sensor. The following shows the color sensor.

info.DeviceInfo(1)

ans = 

             DefaultFormat: 'RGB_640x480'
       DeviceFileSupported: 0
                DeviceName: 'Kinect Color Sensor'
                  DeviceID: 1
     VideoInputConstructor: 'videoinput('kinect', 1)'
    VideoDeviceConstructor: 'imaq.VideoDevice('kinect', 1)'
          SupportedFormats: {'RGB_1280x960'  'RGB_640x480'  'RawYUV_640x480'  'YUV_640x480'
                               'Infrared_640x480'  'RawBayer_1280x960'  'RawBayer_640x480'}

The following shows the depth sensor, which is Device 2.

info.DeviceInfo(2)

ans = 

             DefaultFormat: 'Depth_640x480'
       DeviceFileSupported: 0
                DeviceName: 'Kinect Depth Sensor'
                  DeviceID: 2
     VideoInputConstructor: 'videoinput('kinect', 2)'
    VideoDeviceConstructor: 'imaq.VideoDevice('kinect', 2)'
          SupportedFormats: {'Depth_640x480'  'Depth_320x240'  'Depth_80x60'}

You can use multiple Kinect cameras together. Multiple Kinect sensors are enumerated as DeviceIDs [1] [2] [3] [4] and so on. For example, if you had two Kinect cameras, the first one would have Kinect Color Sensor with DeviceID 1 and Kinect Depth Sensor with DeviceID 2 and the second Kinect camera would have Kinect Color Sensor with DeviceID 3 and Kinect Depth Sensor with DeviceID 4.
