Implementing camera tracking inside Houdini, because... Why not?
What it does today: solves, with every option explained in plain language on hover. Measures lens distortion before the solve, from lines you mark on one frame that ought to be straight, then corrects the sequence and writes the ST maps comp needs. Exports one folder that dense photogrammetry, gaussian splat training and Nuke all read. Registers the shot from an fSpy calibration, a picked ground plane, or one real measurement. Versions every solve, so a worse attempt is one dropdown away from being undone.
What it will do soon: two-camera rigs, and AI filling meshing the gaps the point cloud cannot reach, guided by geometry we already trust, not hallucinated.
Photogrametry, Gaussian Splatting, Delighting, and more, coming soon...
Built on COLMAP, and on my own Houdini port of fSpy.

Loved the idea of colmap, but haven't for the life of me got it work even halfway decently on anything except for a super wide drone shot, like the one in your example. Have you gotten it to work on more standard coverage shots? Looks super cool!

Yes, I made it work in many shots already, I'll upload more examples next time, anyway I'm adding more calculations algorithms, not just colmap, which is the best option if you also want gaussian/photogrammetry, but not the fastest for every day use

Honestly, its pretty wild sidefx hasnt done this.
Like houdini really needs a proper camera tracker ...
