METHOD, DEVICE AND PROGRAMM FOR MEASURING GEOMETRIC VARIABLES OF A STRUCTURE CONTAINED IN AN IMAGE

摘要

The invention relates to a method of measuring geometric variables of a three-dimensional structure contained in an object from at least on image representing the object, having the following steps:- use of a deformable first model describing the structure, the shape of which model can be described by parameters,- adjustment of the first model to the structure in the image,- determination of the parameters at which the first model exhibits optimum conformity with the structure,- use of a deformable second model describing the structure, which second model in shape corresponds to the first model, and which in addition contains at least one geometric variable,- modification of the second model according to the parameters determined, and- derivation of the geometric variable(s) from the modified second model.
