Definitions

  • W02008070537A2 makes the upper, the sole and the insole according to the selected foot vector and according to images of the 3D foot model.
  • the system and method described in W02008070537A2 are somewhat complex and expensive because they require 3D scanning systems and a software program for making 3D models. Moreover, they require the use of processors with an extremely high computational level.
  • the system since the system is designed to scan the user's foot completely, the customer must physically go to the store or to the factory equipped with said 3D scanning system. Therefore, the customer cannot receive information on the footwear that is most suitable for his or her foot while comfortably remaining at home because the scanning systems are extremely expensive and therefore they are not accessible to all users. So, the system described in W02008070537A2 is rather inconvenient and complicated for a user to use. Moreover, such a system is rather inconvenient for shopkeepers or shoe manufacturers because they will have to buy the entire scanning system, with a purchase cost as well as maintenance and management costs.
  • the system for choosing an article of footwear according to the invention is defined by the independent claim 1 .
  • Fig. 1 is a block diagram of the system for choosing an article of footwear according to the invention
  • Fig. 2 is a view of an image of a sole of a foot captured by the image capture means of the system according to the invention
  • the system (100) comprises: - image capture means (1 ) suitably configured to capture an image
  • the image capture means (1) may be a camera, a scanner or another type of optical detector.
  • Vs size vector
  • Each reference table of the table matrix (M) has been created experimentally and comprises twelve full/empty ratios that correspond to a given size and to a given fit of the footwear. By way of example, if there are 30 footwear sizes and 10 fits for each size, the table matrix (M) will contain 300 reference tables.
  • Lisfranc joint identified by a second straight line (r2) inclined with respect to the longitudinal axis (X) by an angle (b) lower than 90°.
  • r2 a Lisfranc joint identified by a second straight line (r2) inclined with respect to the longitudinal axis (X) by an angle (b) lower than 90°.
  • the foot can be divided into three macro-regions: hindfoot (R1), midfoot (R2), and forefoot (R3).
  • the forefoot (R3) goes from the second straight line (r2) corresponding to the Lisfranc joint to a third straight line (r3) passing through the front end of the hallux.
  • the third straight line (r3) is orthogonal to the longitudinal axis (X).
  • the forefoot (R3) comprises the following detail areas: internal transverse arch (I), external transverse arch (L), first metatarsal end (M), second and third metatarsal end (N).
  • the detail areas vary from foot to foot and greatly influence the type of fit. Therefore, the purpose of the invention was to find a system for measuring such detail areas of the foot.
  • the inventor created a database with a plurality of tables containing twelve full/empty ratios correlated with the model, the size and the fit of the footwear.

Abstract

Système (100) permettant de choisir un article chaussant et permettant de capturer une image (Im) d'un pied pour obtenir une semelle ou morphologie de référence, de mesurer une longueur (Lp) du pied pour appliquer des valeurs de constante de calcul et d'égalisation, de construire une grille (Gr) sur l'image comprenant douze carrés (Q), de calculer des rapports complets/vides (R) des douze carrés de la grille et de les stocker dans une table d'utilisateur (T), d'utiliser la longueur (Lp) du pied et de la table d'utilisateur (T) dans une table de recherche (7) d'une base de données pour trouver une taille (S*) et un ajustement (C*) d'un article chaussant qui est le plus approprié par rapport au pied de l'utilisateur.
