Hello ,
I have a problem with calibrating my android tablet camera. I have installed an app on my tablett, and another one on my PC. So I can use my tablet as a webcam. So far so good.
I then use camera_calib.exe file for generating camera_para.dat file like it is described here:
http://www.daslhub.org/unlv/wiki/doku.php?id=nxt_ar_toolkit
I did it twice, but I am not happy with the result. All tracked marker (I took some squared control planes for checking) are 2D shifted against live camera stream.
Is there a way to edit camera_para.dat by hand ? Just to set a different “Point of Interest” or similar?
Calculated FOV seems to be ok, marker lines are parallel by any viewing angle but still not matching. (its 2D shifted)
There are other tools for generating camera_para.dat like described here:
http://www.hitl.washington.edu/artoolkit/documentation/usercalibration.htm#onestep
Is this older or newer? Or even more exact? I do not have any calib_dist.exe or calib_cparam.exe. Where can I download?
Do I even have to change some C++ lines or xml or whatever.
Of course, I can change camera yaw and pitch a little to compensate this shift in bluprint, but I would like to do a more proper calibration.
Thanks,
