Kinect v2 Preview(1)

Microsoft

The New Kinect is released.

In this blog, I'll introduce some information about New Kinect
which is Kinect v2, and share some codes with anyone who is interested in Computer vision.

The performance of Kinect v2 is improved remarkably comparing to the previous version.

First of all, measuring depth method is changed from structured light pattern to TOF(Time of Flight).
Therefore, the density of depth image is quite greater than previous one and the resolution of color image is also improved to FHD.

The detail specification is as following.

Resolution (pixel)

	Kinect v1	Kinect v2
Color	640x480	1920x1080
Depth	320x240	512x424

FOV (deg)

	Kinect v1	Kinect v2
Color	62x48.6	84.1x53.8
Depth	57.5x43.5	70.6x60

And the remarkable improvement is the number of people of skeletal tracking simultaneously.
In Kinect v1, only two people can tracked at the same time, but by Kinect v2, six people can be tracked.
And they additionally provide thumb tacking or end of hand tracking.
I'll discuss detail in few days.
Lastly, the working range is improved due to the method of measuring depth.
Using TOF method, the working range in Kinect v2 is 0.5m ~ 8m.

Up to here, I briefly mentioned about characteristics of Kinect v2.

From the next post, let's share some codes and practice some applications using Kinect SDK v2.

Thank you for reading.
