Corisco: Robust edgel-based orientation estimation for generic camera models

作者:

Highlights:

• We propose an orientation estimation method based on edgels and M-estimation.

• Edgels are extracted with a grid mask that can compromise between speed and accuracy.

• Any camera model can be used, and errors are calculated on the original image space.

• The estimation starts with a random search and ends with a continuous optimization.

• The method uses quaternions, and all derivative calculations use closed formulas.
