Why is it needed for us to calibrate the depth camera and color camera of a Kinect? -


i new kinect. used see on internet joint depth camera , color camera calibration of kinect has been finished when goes out of factories. what's meaning of calibration second time? on other hand, know there applications such many somatosensory games use kinect, how these applications finish calibration? seems impossible game players uses kinds of calibration algorithms done. thanks!

the kinect has indeed internal calibration. in software can therefore use coordinatemapper functions go xyz world coordinates uv color image coordinates.

now imagine following, send xyz data , color image else (or different computer later processing). have no contact kinect anymore, can't ask coordinatemapper how relate 2 dataset.

this why people own kinect calibration. because calibration parameters available , can shipped xyz , uv data.

that said, if don't need this, stick coordinatemapper! calibration of kinect not easy realize.
