Abstract

"PROCESSO DE MONITORAMENTO DO FLUXO DE TRáFEGO, E, SISTEMA DE PRODUçãO DE IMAGENS DE VìDEO". O fluxo de tráfego através de uma área é monitorado pela produção de uma imagem de vídeo da área utilizando uma câmera (10), dividindo a imagem de vídeo em uma matriz de pixéis (23), amostrando os pixéis (23) de toda a imagem de vídeo a baixa resolução para detectar as mudanças nos pixéis (23) que indicarão um objeto de interesse e a amostragem dos pixéis de uma área local (25) da imagem de vídeo centralizada no dito objeto de interesse, a alta resolução para detectar o tamanho do objeto de interesse e sua direção de movimento.
