From c1c3d8c0e3a329fa0d3a93765799c32c8894c33d Mon Sep 17 00:00:00 2001 From: Peter Law Date: Tue, 18 Oct 2022 18:53:38 +0100 Subject: [PATCH 01/18] Convert vision API to using radians The SR vision API now uses radians due to moving to `zoloto`. This commit does not change the shape of the API, just the units, so that the API shape changes can happen separately. This converts all computation and APIs, however keeps degrees in the tests and other places where humans need to eyeball the numbers to understand them. --- modules/sr/robot3/coordinates/polar.py | 6 ++--- modules/sr/robot3/coordinates/tests.py | 32 ++++++++++++++++++------ modules/sr/robot3/coordinates/vectors.py | 9 +++---- modules/sr/robot3/vision/tests.py | 18 +++++++------ modules/sr/robot3/vision/tokens.py | 26 ++++++++++++------- 5 files changed, 60 insertions(+), 31 deletions(-) diff --git a/modules/sr/robot3/coordinates/polar.py b/modules/sr/robot3/coordinates/polar.py index 6cc5a878..b3cc7bff 100644 --- a/modules/sr/robot3/coordinates/polar.py +++ b/modules/sr/robot3/coordinates/polar.py @@ -21,7 +21,7 @@ def polar_from_cartesian(cartesian: Vector) -> PolarCoord: Compute a `PolarCoord` representation of the given 3-vector compatible with libkoki's "bearing" object. - Returned angles are in degrees. + Returned angles are in radians.
