Sensibility, relative error and error probability of projectiveinvariants of planar surfaces of 3D objects

摘要

Presents the study of the sensibility, relative error and errorprobability of projective invariants of planar objects. The study isapplied to configurations of groups of five points which define a planarobject. The results are general for any type of projective invariant.The paper shows that given the precision (or tolerance) and the maximumallowed error probability, the sensibility and relative error can beused to decide the correct configurations for the matching procedurebetween the model and the projective view of a physical object. The lastresult is general for any type of geometric invariant
