[en] SURVEILLANCE AND MONITORING OF VEHICLES IN REAL TIME AT HIGHWAYS WITH NON-CALIBRATED CAMERAS / [pt] VIGILÂNCIA E MONITORAMENTO EM TEMPO REAL DE VEÍCULOS EM RODOVIAS COM CÂMERAS NÃO-CALIBRADAS

MAURICIO AZEVEDO LAGE FERREIRA 23 January 2009 (has links)
[pt] Sistemas computadorizados de vigilância de veículos têm despertado grande interesse devido à demanda para automatizar tarefas que atualmente são realizadas por operadores humanos. Porém, para realizar estas tarefas é preciso resolver alguns problemas clássicos de visão computacional como sombras, oclusões e variação de iluminação. Este trabalho propõe algoritmos em tempo real para máquinas de baixo custo com o objetivo de rastrear, classificar e determinar a velocidade de cada veículo de uma rodovia. / [en] Vehicle surveillance computerized systems have grown great interest due to the automatizing duties demand, which recently executed by computer vision like shadows, occlusion and light variation have to be solved. The present work proposes real time algorithms for low cost machines focused on tracking, classifying and determining each vehicle`s speed on a highway.
