Abstract

DISPOSITIVO PARA DETECÇÃO DA GEOMETRIA TRIDIMENSIONAL DE OBJETOS E PROCESSO PARA OPERAÇÃO DO MESMO A presente invenção refere-se a um dispositivo para detecção da geometria tridimensional de objetos (9), especialmente dentes, com uma peça manual (1), que apresenta ao menos um sensor de posição (12) para detecção da alteração da posição espacial da peça manual (1) e uma instalação óptica (2) com ao menos uma câmera (5, 6) para tomada de imagens e com ao menos uma fonte de luz (3) para ao menos um projetor (4). Inicialmente, pelo sensor de posição (12) na peça manual é determinada a extensão de uma alteração da posição espacial do dispositivo. Disso é determinado quantas tomadas são feitas pela câmera (5, 6) em uma unidade de tempo definida.
