AUTOMATED 3-D MODELING OF SHOE PARTS

A method for analyzing scans of a shoe part to generate dimension data, which is useable to model three-dimensional features of the shoe part is disclosed. The method comprises: attaching a shoe bottom onto a lasted shoe upper, such that a terminal edge of the shoe bottom encircles the lasted shoe upper; projecting a laser beam onto the shoe bottom and the lasted shoe upper, such that a first segment of a projected laser line extends on the shoe bottom and a second segment of the projected laser line extends on the lasted shoe upper; recording an image of the projected laser line that depicts a first-segment representation and a second-segment representation, wherein an interface region between the first-segment representation and a second-segment representation represents a position of the terminal edge; identifying a coordinate point of the interface region that defines a position of the interface region as depicted in the image; and converting the coordinate point to a geometric coordinate point of the lasted shoe upper, wherein the geometric coordinate point is deemed a bite point that represents a position on the lasted shoe upper that is aligned with a portion of the terminal edge.
