摘要:We have developed some human sensing systems that can be used in real time environments, such as on railway station platforms and at railroad crossings, to increase safety in busy public places. We describe an application for counting the number of people remaining in divided areas in large spaces. For this purpose, we installed stereo cameras on ceilings that point downward towards the boundaries of specified areas. The system can track all the people passing in each camera's view and can count the number of people remaining in each area. The system can work robustly even under extreme lighting variations by using the stereo cameras. It was used at “EXPO 2005 Aichi, Japan,” and was active opening hours a day for six months. We have stored all the tracking and counting data to make a precise analysis of the human behavior.
