Ultrasonic and Pyroelectric Sensory Fusion System for Indoor Human / Robot Localization and Monitoring

Abstract: Indoor localization and monitoring system is a key factor in various emerging fields. Localization aware computing has greater advantages in defence sectors. The technology is used all over in places where security problems are a major issue. Localization and monitoring in a real time remote environment is a strenuous process. Although there are several monitoring systems and approaches, issues and problem regarding their shortcomings remains consistent. The most widely used system includes the use of a pyroelectric sensor. The pyroelectric sensory system alone provides less accurate information of human localization and is restricted when there are multiple targets. This system again posses limited accuracy. In this paper a fusion system module of both ultrasonic and pyroelectric sensors are used. The system is experimentally demonstrated, this methods successfully tracked multiple targets in a real-time environment. This fusion method possesses good accuracy and efficiency. With this accurate localization mechanism for indoor environment, the provision of appropriate services for people can be realized, including medical needs
