Hi everyone,
 
I'm having trouble with caliberating 3 overhead photos (same camera, same zoom). After placing about 8 markers I get a message which states that the caliberation process was completed. While all the markers do turn green, then seem to be 'stuck' (no locator name next to the markers, just X). I can't neither model off the caliberation nor measure off it.
I've tried adding aditional markers but that doesn't seem to help...
 
Does anyone have a clue on how to fix the problem?
 
I also have a different problem with determing the focal length of the photo. In the exif of the file I have two focal length parameters: 'focal length' and 'focal length i 35mm film'. which do I choose?
 
Thanks in advance!

Hello,
 
  If you don't see 3d locator (a point + locator name)  near the cross marker, that means tha the 3d projection of the locator is bad...
 
Try the following:
Edit the camera device associated to the 3 shots; you should have only one; As you have same zoom, put focal lenght param to constant. Put distortion param to constant also.
 
If this does not work, could you please send your images and rzi file to support@realviz.com ?
 
Best,
 
Stef

I just found out that for some reason my locators do exist but they seem to be hiding behind the picture (I see only X, no text). Because of that I can't either measure nor model of the photos. How can I move the locators so that they will apear on to of my pictures?
