For collecting manufacturing data for equipment for production of artificial support members or replacement parts (dental bridges, dental caps, etc.) for the human body, a camera (2) is used for stereophotography. The camera is arranged to take simultaneous pictures (3a, 3b) of the respective body area from different angles at one and the same exposure. Reading equipment scans the said pictures which have been taken and provides digitized data concerning the structure/shape, etc. of the respective area or object/implant. Computer equipment uses the digitized data and can graphically reproduce on its screen, or automatically reproduce, the picture which has been taken. With the aid of identification software, points are identified which are used for calculating the spatial position by means of photogrammetric calculation of spatial coordinates. The manufacturing data is generated as a function of the identifications and calculations which have been made.

Pour collecter des données de fabrication d'équipements de production d'éléments de support artificiels ou de pièces de remplacement (bridges, chapes dentaires, etc) pour le corps humain, on utilise un appareil (2) de stéréophotographie conçu pour prendre des photographies simultanées (3a, 3b) de la zone du corps respective sous différents angles et en une seule exposition. Un équipement de lecture balaye lesdites photographies et produit des données numérisées relative à la structure/la forme, etc de la zone, de l'objet ou de l'implant respectif. Un équipement informatique utilise les données numérisées et peut réaliser une reproduction graphique sur son écran ou une reproduction automatique de la photographie prise. Avec l'aide d'un logiciel d'identification, on identifie des points utilisés pour calculer la position spatiale par calcul photogrammétrique des coordonnées spatiales. Les données de fabrication sont générées en fonction des identifications et des calculs effectués.
