Abstract
MÉTODO DE RASTREAMENTO DA ATIVIDADE DE CUIDADOS DENTÁRIOS DE UM USUÁRIO, APARELHO DE RASTREAMENTO, PROGRAMA DE COMPUTADOR .Um método para rastrear a atividade de cuidados dentários de um usuário compreendendo receber imagens de vídeo do rosto de um usuário durante, por exemplo, uma sessão de escovação dos dentes e identificar, em cada um de uma pluralidade de quadros das imagens de vídeo, características predeterminadas do rosto do usuário. As características incluem pelo menos dois pontos de referência invariáveis associados ao rosto do usuário e um ou mais pontos de referência selecionados a partir de pelo menos posições de características da boca e posições de características dos olhos. Características de marcação predeterminadas de um aparelho de cuidados dentários, por exemplo, uma escova em uso, são identificadas em cada uma da pluralidade de quadros das imagens de vídeo. A partir de pelo menos dois pontos de referência invariáveis associados ao nariz do usuário, é determinada uma medida de distância entre pontos de referência. Um comprimento de aparelho normalizado pela distância entre pontos de referência é determinado. A partir de um ou mais pontos de referência selecionados a partir de pelo menos posições de características da boca e posições de características dos olhos, é determinada uma ou mais distâncias de aparelho para a característica facial, cada uma normalizada pela distância entre pontos de referência. Um ângulo do aparelho para o nariz e um ou mais ângulos do aparelho para a face são determinados. Usando os ângulos determinados, o comprimento normalizado do aparelho e as distâncias normalizadas do aparelho para o aspecto facial, cada quadro é classificado como correspondendo a uma de uma pluralidade de possíveis regiões dos dentes sendo escovado.
