Mateo de Mayo dad7957fb2 a/math: Add clock_offset.h 
For now it only has our simple exponential smoothing clock offset estimator.
But more advanced ones can go here too.

Moses Turner 543a436c99 m/relation_history: Add motion estimation 2022-06-18 21:50:14 +01:00
Mateo de Mayo 326402da2a a/math: Use angle as magnitude of change in m_filter_euro_quat 
Previously this was using math_quat_len which was always 1 for
these unit quaternions. This commit assumes math_quat_ln works properly which is
not exactly true at the moment and the returned angle will be twice as large.

Mateo de Mayo e7c3376612 a/math: Add disabled test to show problem with current quat_exp implementation 2022-06-02 15:47:57 +00:00
Campbell Suter 0f8da1900b a/math: Fix math_pose_invert breaking on rotated poses, and add a test 
Previously, math_pose_invert would apply a multiplication in the wrong
order. This lead to the position of the 'original' pose being rotated.

This patch fixes that, and adds a unit test to check this case.

Mateo de Mayo 29aefe2ba8 misc: Use pretty printers and remove stale matrix print functions 
Use u_pp_matrix_* instead.

Mateo de Mayo 05b8e320a5 a/math: Add multiple isometry-related matrix functions 
An isometry is a rigid body transform. In this context I'm using the term to
refer to 4x4 homogeneous matrices in SE(3). I.e., matrices comprised of a
3x3 rotation, a 3x1 translation, and a [0,0,0,1] last row.
This matrix represent both rigid body transforms.

Mateo de Mayo 8b2fa955b9 a/math: Fix matrix identities and use isometry 
Isometry3f is a 4x4 matrix transform that performs only rotation and translation
(an SE(3) matrix). Its inverse can be computed trivially by Eigen compared to a
regular 4x4 transform.
