Counting people getting in and out of a bus by real-time image-sequence processing

摘要

The number of people getting in and out of a bus is an important parameter to allocate the proper number of buses for each connection-line of a public transport service. On the other hand, the correct distribution of the available buses over the different paths, is fundamental to obtain an optimization of the whole transport network, and to reduce costs. In this paper, an automatic system using dynamic image sequence processing to count people getting in and out of a bus is presented. Some fast algorithms are used to detect motion, estimate its direction, and validate the presence of moving people. The system can deal with vibrations, lighting fluctuations and environmental variations. The main advantages are the execution speed and the reliability of the counting process, is performed correctly even if people flow in a chaotic and very clustered way.
