Embodiment Construction
[0041] Figure 1 shows a cross-sectional view of an optical sole scanning device 10 according to the prior art in use, wherein the longitudinal arch of a foot 18 to be scanned is shown. The optical foot scanning device 10 comprises a glass plate 12 having a foot placement side 12a and a scanner side 12b, wherein a scanner 14 with a scanner unit 16 is arranged on the scanner side 12b of the glass plate 12 . During operation, the feet 18 are placed on the foot placement side 12a of the glass plate 12 . The scanner 14 images different areas of the foot 18 during operation: the toe area 20 , the ball of the foot 22 , the arch 24 and the heel 26 . The shape of the feet 18 changes due to the placement of the feet 18 on the rigid glass plate 12 . The toe area 20 , the ball of the foot 22 and the heel 26 are placed flat against the glass plate 12 over a wide area. Even the arch 24 is lowered relative to the unloaded foot shape and / or relative to the naturally loaded foot shape.

Abstract
An optical foot sole scanning device comprises a) an element having a substantially plate-shaped or wedge-shaped shape in an unloaded state and made of an elastic material, the element having a foot placement side facing, in use, a foot sole of a person's foot to be scanned, and having a scanner side, the elastic material is at least partially light-transmissive; b) an optical scanner arranged at a scanner side of the element, and configured to emit, in use, electromagnetic radiation passing through the element to at least partially reach a foot placement side of the element, and configured to record, in use, data, and c) an evaluation unit connected to the optical scanner and arranged to perform a reconstruction of the three-dimensional shape of the sole from the data recorded by the optical scanner. The invention further provides an orthopedic insole scanning system with the optical sole scanning equipment, insole production equipment with the optical sole scanning equipment, a method for determining the three-dimensional shape of the insole and a method for automatically producing the insole.
Description
technical field [0001] The invention relates to an optical sole scanning device, an insole production device having the optical sole scanning device, a method for determining the three-dimensional shape of an insole, and a method for automatically producing an insole. In particular, the present invention relates to an orthopedic foot scanning system comprising an optical foot scanning device. Background technique [0002] Insoles are used for a variety of purposes, including for the relief of physical ailments such as arthritis, sciatica, overstrained feet, damaged or misaligned pelvis, or scoliosis due to differences in leg length. In addition, insoles may also be used by asymptomatic individuals for non-orthopedic purposes, such as improving athletic performance or comfort while wearing shoes. Standardized insoles and individualized insoles, ie insoles which are already adapted to the foot, are known. Individually manufactured insoles are better suited to alleviate said ...
