Shoe last is the benchmark of shoe style in the shoemaking technology and the foundation of shoemaking. At present, how to constitute the last 3D free-form surface model rapidly is one of the important subjects about the last design and the sole mould manufacture. On this basis, the reverse engineering technology was introduced to expatiate its application in the shoemaking industry. The key techniques of the last 3D free-form surface reconstruction were focused. And the reverse processing procedure of the last was set up; the fast reconstruction of the last 3D free-form surface model was also realized. The research has certain directive significance to the concrete application and further popularization of reverse engineering technology in the shoemaking industry.
