| Abstract(in English) | It is very effective to extract human behavior and control building facilities based on the behavior in smart buildings that should provide safe, comfortable and convenient environment with energy saving. We have been doing research on extracting the human behavior with sensor networks using pyroelectric infrared sensors that are very inexpensive and used widely for security and facility control. The sensor networks provide information of human motion but not their quantitative information such as head-counts. We consider counting people existing in each area of buildings with counters placed on their entrances and utilize the pyroelectric infrared sensor for the people counter. The dual element type sensor with Fresnel lens having a pair of detecting areas detects numbers and directions of pedestrians. According to experiment for various passing movements with various temperature difference between the pedestrians and a floor, we confirmed that the sensor can count the number of people correctly except some limited cases such as plural pedestrians in vicinity less than 30cm and very small temperature difference. We implemented the improved algorithm counting pedestrians sequentially in a prototype and got good results in an experiment in a panel exhibition site. We also started to consider how to count pedestrians walking in various directions. |
