mini set not working with reactivision 1.5 ? #37

Closed blaisegeo closed 2 years ago

blaisegeo commented 5 years ago

Hi I installed http://prdownloads.sourceforge.net/reactivision/reactivision_1.5.1-1_amd64.deb on a debian system. It"s ok with the default fiducials: I can see the green numbers on each default fiducial when put under the cam, but I'ld like to use the mini set of fiducials. I updated the reacTIVision.xml file with this line:

<fiducial engine="amoeba" tree="mini.trees" />`

or this one:

<fiducial amoeba="mini" />

But it seems reactivision can't detect these mini fiducials. Is there a special trick to use these mini fiducials ? Would reactivision 1.6 better work than 1.5 ? (Then I'ld have to compile it). If 1.5 is really not working with the mini fiducials, can it work with the "small" set ? Thanks in advance

Not sure if I remember 100% correctly, but try adding the full path to the respective .trees file in the XML. I have successfully used both sets with unmodified reactivision 1.5.1.

Thank you so much, floe, full path to the .trees file made it work !
