  Matching Cameras (Message 1 to 5 of 5)

Given a photograph for a background "plate", I want to 
render an object in POV that will be composed into the 
photo.  So, I need to make the camera position and 
perspective match the photo.

Given a square of a known size in the x-z plane visible in 
the photo, supposing one corner of the square is the origin, 
has anyone already made a script or spreadsheet or something 
to figure it out?  That is, given the length of the two 
sides and the angle between them, calculate the camera 
position.

This make me think of a great tool I found when I was using windows. 
It's name was "Photo Modeler 3d". It was able to take a bunch of photos 
with "common points" and give a 3d model of the object. I've tried to 
reimplement this thing by myself but never managed to do it ://

Maybe if someone know the process he could help both of us :))

By now you should really know where to post binaries and where not to do so!
