<p class="MsoNormal">Hi,<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">You need to adjust the geometry which is described <a href="http://www.openrtk.org/Doxygen/DocGeo3D.html">
here</a>. One of the most sensitive parameters is probably DetectorOffsetX.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Adjusting these parameters requires a calibration procedure (see e.g.
<a href="http://doi.org/10.1088/0031-9155/45/11/327">doi.org/10.1088/0031-9155/45/11/327</a>) or an auto calibration method (e.g.

if someone can point me in the right direction I would appreciate it. Possibly in the projection geometry, but is there also a way to determine this offset from the projection images themselves?<o:p></o:p></p>
