Aston martin 3d tracking and insertion

Mon May 26, 2014 7:16 pm

Just a proof of concept.

Was struggling with realistic appearance with native Lightwave render, until switching to octane.

The scene is tracked in syntheyes, then textures extracted in syntheyes. The actor is roughly roto'd and projected onto wrap around geometry for realistic reflections.

There is some tracking slips, as the camera move could never be solved 100%, lens distortion is not factored into the comp and the rolling shutter of the old RED One.

Sweet

good job on this. But ... The matchmove is still not perfect but very close. The car shifts slightly over the duration but still great job. One question how you get the dude's reflection on the car, is it just plane. I understand camera mapped textures onto static geometry for environment.

Thanks

Very cool, yea there is some areas you could tidy up but it would convince vast majority of people. The chaps reflections really sell it.

Well done. Looks very realistic.
My only question was one of scale. Are Aston's that small. The guy looked a bit like a giant beside it. It looked more like a Lotus Elise or Toyota Celica in size.

I could be wrong... just what it seemed.

Well done though. Impressive.

Ya like I said in the description, the matchmove is definitely not 100%...handheld and walking on gravel makes for pretty bumpy footage.

The reflections are a rough roto of the guy, projected onto a 1/2 cylinder stretched to roughly the path he walked.
The real issue is when the camera pans down...his head and upper body gets cut off, which I had to replace in the reflection projection footage

Kinda just arbitrarily chosen....the guy is about 6'2" so keep that in mind

I like it. I think the scale issue is strange. The car definitely seems to be smaller compared to him at the begining of the shot, but it seems (to me) to change.

Great execution, it will definetely fool almost everyone. The guy's performance though... : D

I could see if the height of the lens was calculated too high at the beginning and you are looking down on the car....that may explain it.

The tracking problem was .....I was walking then stopped(almost) and did a basically nodal pan, and syntheyes never really could solve that motion properly. So I think the last part of the solve is pretty accurate, while the first part may be a little off.

It doesn't look like it but this was a tracking nightmare....the combination of walking, then standing with a low parallax almost nodal motion was almost unsolvable. I put in at least 80 manual trackers, but syntheyes never fully understood what the camera was doing.
