 # PoseErrors.jl
 A good overview and rationale behind 6D pose error metrics can be found in the [BOP-challenge](https://bop.felk.cvut.cz/challenges/bop-challenge-2019/#evaluationmethodology).
 They prefer Maximum Symmetry-Aware Surface Distance (MSSD) over Averade Average Distance of Model Points with indistinguishable views (ADD-S = ADI), because they can yield low errors with bad visual alignment.
