Abstract

A proposta consiste em um sistema de marcadores visuais de alta densidade e alcance total (traçado do marcador e procedimento de detecção). O traçado usa um sistema de localização tradicional típico de marcadores de longo alcance. A proposta é, portanto, focalizada no sistema de codificação de informações, que no presente caso está na forma de um código de quatro estados baseado em cores, que dobra a densidade do código em relação aos sistemas tradicionais em preto e branco. Por outro lado, o procedimento de detecção requer muito poucos recursos computacionais, o que o torna muito eficiente e especialmente adequado para dispositivos móveis. O sucesso da técnica está em grande parte nos procedimentos propostos para o tratamento da cor.
