 |
|
Hi,
I have a small annoying problem.
Simle version: I have 2 photos of the plane with dots and I need to match the camera to them.
I know all sizes, so have:
1) made a *.obj file with those dots.
2) Linked the trackers on photo to their 3D position
3)Solved
-> all fine.
But I need second camera to match as well. So
1) Adding second shot (camera)
2) Linking Trackers to the same object.
3) Solving
->Comes out mess using safe algorithm.
I thought it might be a problem with actual photo perspective, BUT if I doing the same in new project (with the same photo but as only 1 shot -1 camera) all solves fine.
So it is still possible to finish the work, but takes more time, files, and cannot compare camera positions straight away.
Does anyone met this problem and knows how to solve it?
Regards
Sergei |

Solved.
Sorry for waste post.
Basically camera was solving, but due to flat surface and unknown FOV it was doing extreme solving - camera very close to plane and FOV is about 160 degrees.
Not sure why, but in new project it gave me a bit more realistic results.
However the Focal Length found in photo details solved all problems problem. |
