Acquiring from Color and Depth Devices Simultaneously
You can synchronize the data from the Kinect® for Windows® color stream and the depth stream using software manual triggering.
This synchronization method example triggers both objects manually.
Create the objects for the color and depth sensors. Device 1 is the color sensor and Device 2 is the depth sensor.
vid = videoinput('kinect',1); vid2 = videoinput('kinect',2);
Get the source properties for the depth device.
srcDepth = getselectedsource(vid2);
Set the frames per trigger for both devices to 1.
vid.FramesPerTrigger = 1; vid2.FramesPerTrigger = 1;
Set the trigger repeat for both devices to 200, in order to acquire 201 frames from both the color sensor and the depth sensor.
vid.TriggerRepeat = 200; vid2.TriggerRepeat = 200;
Configure the camera for manual triggering for both sensors.
Start both video objects.
Trigger the devices, then get the acquired data.
% Trigger 200 times to get the frames. for i = 1:201 % Trigger both objects. trigger([vid vid2]) % Get the acquired frames and metadata. [imgColor, ts_color, metaData_Color] = getdata(vid); [imgDepth, ts_depth, metaData_Depth] = getdata(vid2); end
