Camera Calibration / Strange Calibration Parameters, or okay?
« on: May 12, 2014, 11:28:29 PM »

in the attached screenshots you can see our calibtration parameters.
It's a Panasonic GH3 with 12mm lense - I used a very big TV flat screen.

Why does the graph go down on after the top (Radial distortion)?
All graphs i've seen in tutorials/videos are going up like the right one...

Is this calibration okay?

Thank you!

Hey together!

i worked a lot with Agisoft DEMO in the past weeks for processing our Aerial Photoscans with UAV's.
It works fine, it's easy and the results are good - But now i have these problem:

We have no flight plan of the Scan, no GPS Dates in the picure only the calibrate Camera - How is it possible to set the Coordinate-System to the right place after processing for compatible measurement Software ?

After the picture alignment my coordinate System is totaly distorted. If i want to use the pointcloud for measurements in the "quick terrain reader" for example, the whole scan is one the opposite. So all mountains are holes and i cant determine it.

I have the same problem if i scan a wall with some bottom - i cant do any measurements because in the software after, the wall isn't the wall, it's the roof.....
(I set the position frame right after aligment)

It would be great to get some ans reply - THANK YOU VERY MUCH :)
