  • the model K2 of a standard size shoe is used, but the user terminal 1 may photograph the shoe and transmit the image data to the data providing device 2 as measurement data of the shoe.
  • the calculation processing unit 212 can use the measurement data of the shoe to calculate the three-dimensional shape of the inner surface of the shoe and generate the model K2 of the shoe.
  • the three-dimensional size of the inner surface of the shoe can be calculated in the same manner as the three-dimensional size of the foot. Since only the edge of the outer surface of the shoe can be detected from the image data, the calculation processing unit 212 can calculate the size of the inner surface by regarding, for example, 1 cm inside from the edge as the inner surface of the shoe.
  • the present invention is particularly useful for foot lesion patients who need their shoes customized, but can also be used by users without lesions.
  • commercially available shoes may fit the length of the foot, the width and height may not match the foot, but according to the present invention, the foot care product 5 that can fit the foot to the shoe can be provided by a simple procedure. can be purchased.
  • Guidance data can also be used to predict the occurrence of future lesions and improve walking methods.
  • the calculation processing unit 212 is implemented by software processing in which the CPU 21 reads and executes programs, but it may be implemented by hardware processing such as FPGA (Field-Programmable Gate Array). Also, a recording medium recording a program to be executed by a computer may be provided.
  • the recording medium is not particularly limited as long as it is readable by computers such as CPUs and microcomputers, and semiconductor memories, magnetic disks, optical disks, and the like can be used.
  • Foot care product providing system 1... User terminal, 2... Data providing device, 21... CPU, 22... Storage unit, 3... Manufacturing system, 5... Foot care product, 6... sensor
