Jakob Bornecrantz 63a180cb97 h/mercury: Remove unused variable to fix warning 2023-03-11 14:06:59 +00:00
Moshi Turner 03546e0b99 h/mercury: Add wrist pose initialization guesser 2023-03-07 17:41:49 -06:00
Moshi Turner 3f2b71a9d5 h/mercury: Use post-rotation residual that'll handle big rotations 
Fixes a long-standing bug

Moshi Turner cdd0a6df67 h/mercury: Have a post-translation as well as post-rotation 
For better numerical stability. Shouldn't significantly affect tracking besides slight jitter reduction and very slightly higher accuracy.

Moses Turner 946141ce40 h/mercury: Remove kine_ccdik optimizer 
Goodbye, sweet prince.
This was my first attempt at the "optimizer" piece of our optical hand tracking, and it *did work* dammit! It just wasn't anywhere near as flexible or efficient as Levenberg-Marquardt.
It's worse in every way to the `kine_lm` optimizer, and getting hard to maintain, so we're getting rid of it. Gone, but never forgotten.

Jan Schmidt fc3fbd6093 d/ht: Fix rotation/flipping of right hands 
When dealing with rotated cameras, rotate them backward
to vertical, and then flip the right hand image in
the affine transform to get correct orientation of hands
for the keypoint estimator. Before, the left hand images
were being fed in upside down.
