NEW: Estimate global position transformation #241

Closed carterbox closed 1 year ago

carterbox commented 1 year ago

Purpose

Find the affine transformation which transforms from the initial to final scan positions.

Approach

Use RANSAC and linear least squares to estimate the global position transformation from initial to final positions. This transformation is then decomposed into scale, shear, rotation, translation and is stored as a new AffineTransform dataclass.
