Hi,
one asked me to is that of the "Near Mode" that joins the new Kinect For Windows (something I mentioned here).Obviously the official description is that we can now recognize skeletons less distance than with the sensor for the Xbox, but the issue is more interesting.
Let’s look at some data that can shed light on the matter about how works the Depth Sensor .
- The depth Sensor works with a resolution of 320 × 240 pixels.
- This gives us a total of 76800 pixels
- Each pixel has a position in the painted area and the distance to the Kinect sensor in millimeters.
Rather than identify a color as in the array that returns the camera.
Now well, with the new Kinect For Windows it is possible to work with 2 models
- Default Mode
- Near Mode
To start working with these modes of work we take into account the values of the following graph to understand in what ranks we move.
But not all the capabilities of Kinect are available in both modes, here is a table which shows us what we can identify in each mode
So… it is not that the "Near Mode" we all work from 40 cms capabilities, but will have the ability to identify 1 to 6 skeletons, but not with all the points of each.
