Re: Tracking Tools + VRPN
<t>I have a similar need. I would like to set the pivot point to a precise position in the rigid body. A very simple solution (software wise) would be to allow to set the pivot point at an offset on a line between two markers. <br/> <br/> Example :<br/> <br/> - create a tracker with 3 or more marker...

Re: Intrinsics camera parameters
<t>It is quite surprising. In what context?<br/> <br/> OpenCV algo is quite rudimentary, and, you probably know better, but I noticed that you must grab chessboards in a very structured manner to obtain good results.<br/> <br/> Where does the precision comes from? Using corner-like features allows f...

Intrinsics camera parameters
<t>I tried to search a bit on the forums about this topic without satisfying answers.<br/> <br/> If I understand correctly, the current calibration procedure calibrates both intrinsics and extrinsics using 1 or 3 markers wand. I'm quite surprised you don't offer an intrinsic calibration procedure us...

Re: Calibrating Multiple Camera Groups
Nevermind for the wand's specs, found out required info in another forum thread. I built my own, seems to work fine.
My question about merging groups via their ground plane persists.
Thanks

Re: Calibrating Multiple Camera Groups
<t>What about calibrating the two groups separately and then setting a common coordinate frame?<br/> <br/> We tried quickly but the tracking was horrible, I will give it another try but are-you aware off anyone having success with that.<br/> <br/> I currently don't have the 3-marker wand, I plan to ...
