焦電スキャニングセンサによる人体検知方法の検討

摘要

人体検知については様々な研究がなされているが，民生用においてはコストが安く,検知の確実性に優れた焦電センサが用いられることが多ぃ.しかし焦電センサは熱量の変化は検知できるが,静止した熱源の存在や，熱源の位置や大きさなどの情報を得ることは難しい.これに対して本研究では，焦電センサを用いて人の存在だけでなく人体が空間上を占める大きさや， 位置が推定できる新規な計測システムを提案する.また本手法を画像処理と組み合わせることで，異なる性質と分布を持つ赤外線受光量と撮影画像の2つの情報の統合を試みた.%New technologies are required to obtain information related to humans, such as their physical position or posture. Many methods are used for human body detection, although image processing is the most popular because it can obtain more information than the others. However, image processing cannot detect a human who does not move when the background is complicated. We propose combining image processing with an estimation of the size of a human body with a scanning pyroelectric electric sensor. When the pyroelectric sensor scans, the volume of the heat source in the rotatory direction is measured. A heat source domain is provided from the image information of the camera photography range. In addition, the position of the person can be measured similarly to stereo-camera measurement if scanned by two sensor units at the same time. In this work, results of measurement by a prototype are discussed.
