摘要

Counting people and observing their movements are essential processes for security, organizational administration, and the improvement of corporate business results. This paper presents a method to automatically count passersby using virtual, vertical measurement lines. Recognizing passersby and generating space-time images are performed using an image sequence obtained from a USB camera. The space-time imagery represents recognizable regions surrounding each person which are identified through labeling-based segmentation. In this study, a space-time image represents time as pixel-distance, which an algorithm uses to achieve highly accurate counting. Human regions are based on space colors processed through template matching to select the optimal match in order to obtain direction and speed. Whether the shape represents one or two passersby is determined through the relationship between the passerby's speed and the human-pixel area. To evaluate the effectiveness of this proposed method, we performed experiments using a side-view camera placed near an entrance. The experiment achieved 97％ accuracy in counting and direction.
