Abstract

"PROCESSO E DISPOSITIVO PARA DETECTAR OBJETOS ILUMINADOS PRESENTES SOBRE UM VIDRO TRANSPARENTE", que produzem reflexos luminosos mediante iluminação sob utilização de uma unidade de detecção provida de uma ou várias matrizes de sensores ópticos, compreendendo as seguintes etapas: iluminação do vidro ara produzir reflexos luminosos em ou junto a objetos presentes no vidro do lado do vidro atrás do qual a unidade de detecção está disposta, captação por imagem de um segmento iluminado do vidro através da unidade de detecção mediante preparação de duas imagens do segmento do vidro, formando um par delas, nas quais o ou os reflexos luminosos de um objeto presente no vidro, produzidos pela iluminação, estão dispostos respetivamente em elementos de imagem de diferentes posições, determinação da imagem diferencial a partir das duas imagens que constituem um par delas mediante subtração dos dados de elementos de mesma posição de uma imagem do segmento do vidro, dos dados da outra imagem do segmento do vidro e análise subsequente da imagem diferencial determinada com relação aos dados atribuídos a cada um dos elementos de imagem.
