Abstract: A support plate with a horizontal flat standing surface carries two posts, and is rotated about a vertical axis. A stationary triangulation measuring head having a camera and a light line projector, projects light lines, which are perpendicular to the plane of the support plate, onto a person who stands upright on the standing surface of the plate. Encoded, photogrammetrically evaluatable marks are arranged on the plate around the standing surface and on the post. Images taken by the camera during rotation of the plate are transferred to a computer to determine a three-dimensional shape of the person or of part of the person. Marking-free fields are arranged on the support plate and on the post. The computer determines the parameters of the triangulation measuring head to performs a self-calibration of the detection process based on positions of the photogrammetric marks and shapes of light traces on the marking-free fields.

Abstract: A method and a device for categorizing articles of clothing and a method and a device for selecting footwear having an improved fit are specified. A parameter describing the fit and/or the size of an article of clothing is acquired on the basis of a measurement carried out on the article of clothing in question. This measurement is performed for a plurality of articles of clothing of different manufacturers but having an identical manufacturer clothing size, a plurality of different manufacturer clothing sizes being furthermore considered. A frequency analysis for the occurrence of specific values of the at least one parameter is then performed for articles of clothing having an identical manufacturer clothing size.

Abstract: A method is described for selecting, in a cost-effective and largely automated manner, best fit footwear with an optimally selected or individualized footbed. With the aid of a preferably multisensory foot scanner, the geometric three-dimensional shape of the foot and the plantar pressure image registered with it are determined at the same time. A database of digitized shoe interiors is used for determining, by means of a best fit selection, the series-produced shoe that best matches the 3D foot model.

Abstract: In a cost-efficient method and arrangement for 3D digitization of bodies and body parts, which produces dense and exact spatial coordinates despite imprecise optics and mechanics, the body to be digitized is placed on a photogrammetrically marked surface, a photogrammetrically marked band is fitted to the body or body part to be digitized, and a triangulation arrangement comprised of a camera and a light pattern projector is moved on a path around the body.

Abstract: There is described a method and an apparatus for the optical 3D digitization of bodies and body parts which reveal non-visible regions which therefore cannot be detected by the 3D digitizer. A mechanical aid is fixed at these regions and protrudes into the measurement space visible for the 3D digitizer. On this visible part, it is provided with marks and is digitized together with the remaining, visible body parts. From the spatial position of the marks of these aids, important geometrical information of the non-visible parts, such as the spatial position, circumferential dimensions, etc., can be calculated, and the 3D model of the body or body part incomplete at these points can be completed therewith. Two applications from the field of orthopedics are described by way of example.

Abstract: A method for the three-dimensional, digitized sensing of the spatial shape of at least one foot of a person. The method includes: determining a desired position for the foot which is predefined by the footwear to be selected or fabricated; moving the foot to the desired position by means of a device which can preferably be adjusted using a motor; optical sensing and digitizing the three-dimensional spatial shape of the foot in the desired position. Furthermore, an arrangement by means of which at least one foot of a person is moved to a desired position and the spatial shape of the foot is digitized in a mainly contactless manner includes a bottom plate, a first support and a second support. The first and second supports are movable, preferably using a motor, parallel or perpendicular to the bottom plate to move the foot to the desired position.

Abstract: The invention relates to a method for detecting the three-dimensional shape of an object (2) during which an object (2) provided with photogrammetrically evaluable marks (4) is placed on a surface (5) at a predetermined location. This surface is provided with additional photogrammetrically evaluable marks (6) that are arranged in a predetermined manner with regard to one another. The surface extends in such a manner that the additional marks (6) are arranged around the contact surface of the object located on the surface. A number of images of the object (2) are taken from different views so that, in addition to the object (2), the surface (5) is also at least partially depicted. The three-dimensional shape of the object is determined from the images with the aid of the markers (4) of the object and of the markers (6) of the surface (5) by using a photogrammetric method.

Abstract: There is described a photogrammetric method and an arrangement for the three-dimensional digitizing of bodies and body parts (26) which are covered with a marked, elastic cover (14), which comprises high-contrast marks which are photogrammetrically analysable, and which are photographed from different shooting positions. For the purpose, at least one camera (22) is moved around the body with a simple, inaccurate guide and images overlapping each other are taken from different positions in space to cover both the body and several of the marks (10) of the support (12). Methods of photogrammetry as well as digital image processing and pattern recognition provide precise space coordinates of the body to be digitized. One exemplary application is the digitizing of the foot/lower leg portion for the selection or custom manufacture of anatomically well-fitting footwear, the digitizing of the leg portion for the manufacture or selection of well-fitting compression stockings.
