Title:
DATA OUTPUT RESTRICTION DEVICE FOR SOLD OBJECT MOLDING
Document Type and Number:
Japanese Patent JP2017207900
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a data output restriction device for solid object molding which can accurately determine whether or not to restrict outputs, using a two-dimensional image as a reference, when outputting a sold object on the basis of a polygon model.SOLUTION: The data output restriction device comprises: image frequency distribution calculation means 92 for calculating the radius of a circumscribing circle of a triangle between edge points formed by three edge points of an object extracted from a restriction image, and calculating a circumscribing circle distribution that is the frequency distribution of circumradius while weighting on the basis of the edge strength and edge direction vector of the three edge points; model frequency distribution calculation means 10 for calculating the radius of a circumscribing circle of a triangle between polygons formed by points on three polygons in an object model, and calculating a circumscribing circle distribution that is the frequency distribution of circumradius while weighting on the basis of the areas and normal vectors of the three polygons; and frequency distribution collation means 20 for collating the circumscribing circle distribution of the restriction image with the circumscribing circle distribution of the object model and determining whether or not to restrict outputs.SELECTED DRAWING: Figure 17
