Does anyone know of an article or web post that has details a solid, realistic procedure for camera matching when faced with minimal information?

For instance, I have measurements off a structure (windows and such), but lack data like distance TO the structure from the camera, and even essentials like focal length are a little dicey.

Thanks. :thumbsup:

This is a technique using SynthEyes but perhaps it's a start.

Thanks Ma3rk, but it would have to be a no-cost solution. (Although, I'm fine w/a watermark or similar limitation.)

I tried the one free (VooDoo?) app, but the results were unsatisfactory. I'm thinking perhaps there's another, better, workflow.

The only thing I can think of is in the Taft plugin collection from Worley - Camera Match.

http://www.worley.com/E/Products/taft/camera_match.html

And now it's only $49! I think I got it when it was $200? ;)

LOL, those were the days.

Unfortunately, IIRC, Camera Match dox specifically warn against using it with a moving camera.

Also, I think I'm underestimating the basic difficulty involved in this task, considering the tales of woe I read.

Don't know if this will help, but I saved it in favourites a long while back.

Sorry, didn't realize this was for a MOVING camera. Maybe PFHoe? At least it's only $99 and there is a free trial.

AE CS6..but definitely not free, except for the full-feature 30 trial might be an option.

Icarus 2.09 (The forerunner of PFtrack) still works if you can find a copy. It's not hard to find.
EDIT: Website with tutorials is here... http://www.colinlevy.com/tuts/IcarusTutorials/Icarus.php

Thanks kyuzo.

The blender matcher has a very limiting weakness in that a purely 'tripod' shot will not solve: there must be some dolly movement in the shot. Grrrrr. ::sigh::

I think you owe it to yourself to check this thread...in-LW tracking.

Hi Jeric,

Icarus can handle tripod/rotation shots. If you download it, you get a 60-page manual with tutorials included.
As there will be no parallax in that type of shot, it cannot construct a 3D point cloud, but it will give you points positioned in a spherical arrangement. From there it shouldn't be too hard to position your model.

Thanks kyuzo, downloading now.... :thumbsup:

BLENDER: besides the "no tripod" issue, there IS the whole "blender UI" issue... and the "blender 'dox' " issue....

(I can see how once you're used to it, the blender UI would be very powerful. Until that time, it's like a stone in one's shoe. It is consistent, I'd say more than LW. But it's very much like looking at a huge wall of 'pigeon holes' in a post office, trying to find the one pigeon hole with the setting you need.)
