Abstract

resumo patente de invenção: "sistema de detecção com base na modulação de imagem de vidro a laser de linha estruturada". um sistema de detecção com base na modulação de imagem de vidro a laser de linha estruturada compreende a seção de processamento (2), o sistema de controle e os mecanismos de condução de rolete (5). o mecanismo de detecção (6) fornecido na entrada da seção de processamento (201) compreende o revestimento e a câmara (602) com laser (601) que emite um feixe na superfície do vidro no vão entre os roletes de deslizamento. o plano focal da câmara (602) corresponde à superfície de irradiação do feixe, e o terminal de emissão de sinal da câmara (602) é conectado ao sistema de controle de tal maneira que quando o vidro passa na área de detecção, o laser irradia a superfície de vidro e o laser de linha estruturada é modulado com base no vidro para formar a imagem de modulação a laser com distribuição de luz e sombra, direção do movimento escalonado, ou linhas de laser distorcidas. a câmara (602) irá transmitir as informações e os parâmetros de vidro capturados para o sistema de controle. no sistema, o mecanismo de detecção (6), com projeto integral e estrutura compacta, pode ser facilmente montado na entrada da seção de processamento (201), ter grande adaptação a outros meios de processamento, não ter requisitos especiais com relação ao ângulo de incidência da luz e ao ângulo de superfície de detecção durante detecção, e obtém os dados de alta precisão através da medição.
