<br>> Hi there,
<br>>
<br>> I have been trying to develop an augmented reality system using position
<br>> sensors and VTK. This augmented reality system would combine endoscope image
<br>> with the 3D VTK model.
<br>> I could successfully make an AR system with Ascension EM tracker, which can
<br>> run on a torso phantom and its 3D model. The tracking of the real and
<br>> virtual scenes looks good.
<br>> However, when I replace EM tracker with the NDI spectra optical tracker in
<br>> the same AR system the tracking of the real and the virtual scene does not
<br>> look good (please look into the images below).
<br>> Do I need to do some tweak to replace EM tracker with NDI Spectra optical
<br>> tracker.
<br>> Any help will be highly appreciated.
<br>>
<br>> Thanks
<br>> Atul
