Rotary three-dimensional foot shape and plantar pressure scanner and working method thereof

Abstract

The invention provides a rotary three-dimensional foot shape and plantar pressure scanner and a working method thereof. The scanner comprises a vertical control platform, a foot shape scanning column,a circular-ring guide rail, a motor, a pressure measuring board, a measurement control board card, an interaction and processing terminal, a protection pad, a network interface, a USB interface, a switch button and an external power cable. The foot shape scanning column is installed at the outer side of the platform base of the vertical control platform and is fixedly connected with the circular-ring guide rail by a screw. The foot shape scanning column is driven by the motor to make constant-speed circular rotation with the circular-ring guide rail. When the column rotates, an upper 3D real-sensing camera module and a lower 3D real-sensing camera module work cooperatively to obtain three-dimensional image data of feet of the user. The pressure measuring board installed in the center of the platform base is used for acquiring plantar pressure distribution data of the user synchronously; the measurement control board card is responsible for controlling the foot shape scanning column and the pressure measuring board to collect data and transmit the collected data to the interaction and processing terminal. Therefore, the foot morphological and sport dynamics parameters of the user can be obtained synchronously, conveniently and quickly and the analysis is fused; complementary scanning is realized; and self-calibration can be carried out.

Description

technical field [0001] The invention relates to the field of foot digital automatic measurement, in particular to a rotary three-dimensional foot shape and plantar pressure scanner and a working method thereof. Background technique [0002] Three-dimensional foot shape measurement technology is the basic technology in the fields of shoemaking, foot disease diagnosis, treatment and rehabilitation, and foot biomechanical analysis and research. In the early days, manual measurement was often used, which had defects such as high labor intensity, low efficiency, and poor accuracy, and lacked the description of the overall characteristic information of the foot shape. With the development of measurement technology, technical methods such as scanning technology, photo synthesis technology, and mold inversion technology have emerged to improve the measurement efficiency and accuracy; the plantar pressure distribution measurement technology is to use pressure measuring instruments to...
