Motion tracking scene upside down

Support Technical Support
#1

Hey all,

I just tracked a scene (of my kids dancing) and thought I did a pretty fair job, solve error of .5xxxx but when I look at my scene in the 3D viewport the whole thing is upside down, the camera and all the trackers, I’ve tried messing with the origin point, wall and floor, but nothing seems to help. Does anyone have any thoughts as to what I did wrong?

Thanks so much for your help

I don’t know much about motion tracking, but I think that the most simple solution is to rotate the camera.

You didn’t tack enough markers. From the screenshot it looks like you tracked mainly on the floor. But that’s not enough. You also need to track something above to establish some depth, for example the sofa. Also don’t just track in the center of the frame, try to spread your tracks as broad as possible.

Thanks Sebastian - I’ll give that a try and let you know how it goes
