Method and device for obtaining a plantar image and double-sided machining of the insole thus obtained

The invention relates to a method for obtaining a plantar image using means for securing and tightening an elastic membrane and for the double-sided machining of the insole thus obtained, said means taking the form of two adjustable horizontal bars positioned on a scanner or a plurality of cameras and an anti-reflective crystal or lens. The invention includes the following steps in which: the membrane is positioned between the horizontal bars and secured using T-bars; the tension of the membrane is adjusted using a handle; the foot is positioned on the membrane; an image is taken; and the insole is subjected to double-sided machining on the basis of the image of the surface provided in STL format, with the aid of a securing device that enables the parts to be rotated through 180°. The device used includes a plurality of supporting bars with two adjustable horizontal bars, and the elastic membrane is adjusted and tightened using T-bars and a handle
