camera tracking/matchmoving problem

Hi,

I'm trying to do some tests to learn camera tracking/matchmoving.

Here are the footage that I'm working on:

I'm not happy with the results. Would you please tell me if the footage are good for the tracking or not.

I used Canon 650D, Lens 22mm and 50mm

Thank you,

The shots look fine. I'd make a little bit more simple a camera move, something that has meaning and is not just "ok I need to move my camera for a tracking test" . That's my 2 cents.

Thank you for your help.

If you're aiming to get a 3d camera, with accurate relative depths of points in the shot, then you need to see some parallax in the scene. Right now, both shots are essentially pans. There's a tiny bit of parallax between the car and the background at the end of the first one, but it's not likely to give you enough data to get a reasonable solve.

You'll certainly encounter shots with that kind of movement in production, but they're not terribly useful for learning. Instead, get something that has a decent amount of lateral motion, particularly something with distinct foreground and background elements. Point the camera down that row of cars on the left of the first shot and walk sideways. Not too quickly, though. Motion blur will make your job harder than it needs to be!

You might also go by the website Hollywood Camerawork. They've got a variety of HD clips available for download that are pretty good to learn tracking on. Lots of greenscreen footage with moving cameras and adequate markers on the walls.
