I'm new to Blender and am trying to track a very simple camera movement : I'm moving my camera from down to up, along a straight line.
I'm using a DJI Osmo camera, so that I get a stabilized image.
I've been able to do put several tracking markers which seem fine.
As I said, the camera movement is very simple : from the bottom position, I move to the top position along a straigt vertical line.
When solving, I put 20mm for camera lens (dji osmo specifications) and 6.16mm for sensor width (again, from osmo specs).
According to many tutorials I've seen/read, I check
keyframe and select
refine focal length, K1, K2.
I thought I had all I need to get a good tracking result, but to my surprise, Blender goes all wrong !
I get a solve error of 3.6 (suprisingly, it seems each time a click on
Solve camera motionI get different results). The lens focal is changed to 150.50mm (!?!), K1 to -488 and K2 to 326227 (!!!).
Is there something specific I should do for tracking such camera movement ?
I've been able to track sucessfully much more complex movements, and have no clues why I'm having such a hard time for this one.
