METHOD FOR DETERMINING A THREE-DIMENSIONAL FORM OF AT LEAST A PART OF A BODY, AND SYSTEM FOR DETERMINING A THREE-DIMENSIONAL FORM OF AT LEAST A PART OF A BODY

摘要

The invention relates to a method for determining a three-dimensional form (FO) of at least a part (ST) of a body (KO), wherein the method comprises the steps of: a) projecting a figure pattern (PM) onto at least the part (ST) of the body (KO), wherein the non-projected figure pattern (PM) comprises a region (BE) of identifiable figures (PU) which repeats in one dimension (y); b) recording an image (BI) of the projected figure pattern (PM) onto at least the part (ST) of the body (KO); c) determining figures (PU) in the recorded image (BI) by detection by means of a neural network (NN), wherein the neural network (NN) is trained to detect the figures (PU) in the region (BE) using training images (TBI) of variously distorted sections (AS) of the figure pattern (PM) and by means of a region index (BEI) of the corresponding region (BE); and d) determining the three-dimensional form (FO) of at least the part (ST) of the body (KO) on the basis of the figures (PU) determined.
