Camera Calibration / Export or convert distortion to 3DE model ? (C4D, 3D equalizer, Nuke etc...)

« on: December 12, 2016, 10:36:17 PM »

Hi,

Is there a way to convert agisoft lense data (fx, fy, cx, cy, K1, K2, K3, P1, P2) to the 3DE lens distortion plugin kit values?

https://www.3dequalizer.com/?site=tech_docs&id=110216_01?

It requires (for the most simple "classic" model) :
x Offset
y Offset
Quadratic
Quartic
Cuvature X
Curvature Y
Anamorphic squeeze

Originally used in the 3D equalizer matchmoving software, it is now available in Cinema 4D (3D modelling), Nuke and even After Effects.

Thanks

General / VideoScan ? Creating simple depthmaps from stereo videos (for compositing)

« on: July 21, 2011, 01:36:33 PM »

I'm a happy user of Photoscan Standard, but also a video fx artist and I was wondering if there was anyway to create a special version/mode of Photoscan to specially deal with stereo videos and only outputting the depthmap/disparity as another video (3D mesh would probably be overkill at that stage).

I see the math and all the building blocks are here already in Photoscan : selecting stereo pairs and creating depth maps but the workflow isn't adapted to video (25fps x 2 eyes : 50 frames per second to match/solve/retrieve by hand)

Ideally a plugin for Aftereffects and such would be great, but a nice and simple standalone app (or a special mode in photoscan) would certainly be a great step forward.

With more and more affordable 3D camcorders and bigger 3D productions, there's definitely a market for that. I know I would pay a premium for that.

Thanks for your consideration.
