3D Work point extraction method for automatic adhesive application from 3D shape data of shoe midsole and extraction device thereof

摘要

The present invention relates to a work point extraction method and an extraction device for automatic adhesive application work from 3D shape data of a shoe midsole, Method of extracting a working point according to an embodiment of the present invention, A first step of receiving 3D shape data of a shoe midsole; A second step of obtaining a point cloud data group by performing a point cloud transformation on the 3D shape data; A third step of dividing the point cloud data group into a plurality of cells and obtaining a first point group having a maximum value in a vertical direction (Z-axis direction) from the divided plurality of cells; A fourth step of obtaining a second point group from which noise data unnecessary for an adhesive application operation is removed from the extracted first point group; And a fifth step of obtaining a third point group that satisfies a preset distance condition from the second point group from which the noise data is removed.
