<p>A method of determining the cutting outlines (2a) of hides (1) provides for the outline (2) of the hide to be plotted by determination of the coordinates (x, y) of a preselected number of points on the outline (2) and/or of points within the outline and storage of the coordinates in a processing unit, for the preselection of sets of geometrical parameters which identify respective defects and/or unusable portions of the hide which can be identified on the outline (2) and/or within the hide such as, for example, indentations (4), projections (5), holes (3) and the like, for the creation of a database containing predetermined values for the said geometrical parameters, preselected in dependence on the degree of imperfection permitted for each defect, and for the provision, for each defect, of a respective algorithm with which the coordinates (x, y) of the points on the outline (2) of the hide are compared in order to identify the defects or unusable portions along or within the outline and to calculate the value adopted by the parameters for each defect identified. The values calculated for the parameters are compared with the corresponding values stored in the database so as to identify regions of the hide having defects with unacceptable degrees of imperfection and the coordinates (x, y) of the outline (2), free of defects, are recalculated in these regions, the outline thus calculated and stored in the processing unit constituting the cutting outline (2a) of the hide which optimizes total area thereof and minimizes waste. <IMAGE></p> |
