  • the aim of the present invention is to provide a unit for measuring body parts and reconstructing them in three dimensions, particularly for manufacturing custom shoes or other body prostheses, whereby it is possible to achieve, in a substantially automatic manner, the measurement and reconstruction, in three dimensions, of the shape of the foot, or of another part of the user, in plan view and in elevation view; the analysis, validation and preprocessing of the acquired data; the comparison with standard-size models; the identification of the differences that must be compensated by the prosthesis to be manufactured; the size assignments, in a virtual environment, of the model for manufacturing the shoe.
  • an object of the present invention is to provide a contactless measurement unit which can be easily integrated with a CAM unit particularly suitable for manufacturing a prosthesis or an entire shoe according to requirements.
  • Another object of the present invention is to provide a unit which is easy to use and for which long training to learn its use is not required.
  • Another object of the present invention is to provide a unit which is highly precise in relation to the field of use.
  • Another object of the present invention is to provide a unit whose components are technologically known and optionally directly commercially available.
  • a unit for measuring body parts and reconstructing them in three dimensions, particularly for manufacturing custom shoes or other prostheses characterized in that it comprises a measurement subsection for contactless measurement of a body part to be acquired and a subsection for processing the data acquired by said measurement subsection, said subsections being mutually associated by a local or wide- area computer connection network, said measurement subsection comprising at least one television camera which is rigidly coupled so that it rotates around a support for the body part to be acquired and is suitable to observe the trace of the contour of the body part obtained by emitting against the body part at least one colli ated laser beam which exits from at least one laser emitter which rotates rigidly with respect thereto, rigidly with said television camera, and is positioned with a preset angle with respect to said television camera.
  • a television camera observe the object onto which a laser beam is projected; said beam forms a bright line (pattern) which has a different shape, in the image, depending on the point being illuminated and accordingly depending on the viewpoint.
  • Said line is acquired and processed in order to obtain the curved line that corresponds to the projection of the laser beam on the object, represented in three-dimensional perpendicular Cartesian coordinates.

  • a unit for manufacturing custom shoes according to the present invention is generally designated by the reference numeral 10.
  • the unit 10 comprises two subsections which are mutually associated by a computer connection network which can be of the local or wide-area type: a subsection 11 for acquiring the dimensions and shape of a body part, for example a foot, designated by the reference numeral 12, and a processing subsection, not shown, for the data related to said acquisition subsection 11.
  • the measurement and acquisition subsection 11 comprises a television camera 13 which is rigidly coupled so that it rotates about a platform 14 on which the foot 12 to be acquired is rested in the illustrated case; the television camera is suitable to acquire the trace 15 of the contour of the foot 12, which is obtained by emitting against the foot a collimated laser beam 16 produced by a laser emitter 17 which rotates about the foot 12 rigidly with the television camera 13, with a preset angle with respect to the television camera.
  • the foot is placed correctly for acquisition by applying optional shims 18.
  • the contour of the foot 12 is measured and acquired by means of the telemetric triangulation method, which allows the television camera 13 to acquire at high speed and with excellent precision the contour of the foot 12 as scanned by the collimated laser beam 16.
  • the data acquired by the television camera 13 are stored and then sent to the processing subsection, in which the solid three-dimensional model of the foot 12 to be reconstructed is generated.

  • the unit 10 Starting from the actual dimensions of the foot, the unit 10, by means of a particular algorithm, determines which volumes exceed the standard model, weighing the
  • Boolean operation by comparing the linear dimensions of the width and length of the sole.
  • the contour of the shoe is obtained by interpolating the excess or missing volumes, so as to make it resemble as much as possible the shape of normal models.
  • the processing subsection produces, as an output, a graphical representation in solid terms and a surface model, from which dedicated algorithms extract the tool path required for the subsequent production of the shape by numeric-control machining with a 3/5-axis mill.
  • the unit 10 also has a frame 19 which is provided with a handrail 20 for support and with a step 21 which is raised with respect to the platform 14 where the foot 22 that is not being acquired is rested.
  • the television camera 13 and the laser emitter 17 are supported by a common arm 23 which is supported, so as to cantilever out radially, by a rotating support 24 which is axially rigidly coupled below the platform 14.
  • the unit 10 also comprises motor and actuator means, generally designated by the reference numeral 25, which are suitable to move the arm 23 around the platform 14.
  • the unit according to the present invention is capable of precisely acquiring, with a very easy operating method, the measurement and shape of the foot or of another body part, reconstructing in three dimensions its morphology and dimensions.
  • the resulting model which is particularly accurate, can be easily sent to a processing subsection, which can thus extract from it the information for proceeding with a subsequent step for actually generating the model by milling.
  • the object might rotate whilst the television cameras and the laser emitters are fixed; the system uses the same principle and the same technology.

Abstract

Ensemble pour mesurer des parties du corps et les reconstituer en trois dimensions, utile en particulier pour la fabrication de chaussures sur mesure ou de prothèses. Le dispositif comporte une section mesure (11) pour mesurer à distance la partie du corps (12) désirée et une section traitement des données provenant de la section mesure (11), ces sections étant mutuellement reliées par un réseau local ou un grand réseau de connexion informatique. La section mesure (11) se compose, si la partie désirée est le pied (12), d'une caméra de télévision (13) qui est montée par un couplage rigide de manière à tourner autour d'une base ou plate-forme (14) sur laquelle le pied (12) repose. La caméra (13) est conçue pour enregistrer le tracé du contour du pied (12) obtenu en projetant en direction du pied un faisceau laser collimaté (16) provenant d'un émetteur laser (17) tournant autour du pied (12) dans une position fixe en même temps que la caméra de télévision (13), et orienté selon un angle prédéterminé par rapport à la caméra de télévision (13).
