Hi,
i am trying to get familiar with Aximmetry and playing around with PTZ (AW UE100) and the camera calibration tool.
I found a good way for getting the markes sticked to my realworld object, but still have some issues with "objects swimming on the floor"
In my scenario i did the following:
- aligned my PTZ to be accurat in level
- used a straight object to adjust the real world with the Pan Virtual
- used a new Camera definition
- edited preferences with sensor size (5.76) and height from floor (137cm)
- added the first calibration point with zoom at the opened end and fixed focus point (4m)
- adjusted the FOV to a suitable value
As you can see at this video (https://www.youtube.com/watch?v=p1EyLlQQi_o ) the straight object is moving on the floor and i dont know how to get rid of this...
Could anybody point me in the right direction ?
Thanks,
Tobi
Hello,
First of all this calibration looks great, keep in mind that it will never be 100% accurate and even the tiniest change in any of the settings can lead to a noticeable drift in the 3d scene.
In this situation you can try to adjust the Focal Lenght value a bit, you can adjust it with 0.001 precision and sometimes it is needed it be set in 0.01 precision
Also if your lens has distortion that could cause a small drift around the edges. Unfortunately in the current version, you can't adjust it. (but we are working on this)
if you have bigger drift when you move your camera faster then you can try to adjust the Tracking Delay
