基于P IR Sensor的单目标跟踪系统的设计与实现
Design and Implementation of Single Target Tracking System Based on PIR Sensor
摘要
Abstract
Due to the effects of the environmental noise and hardware parameters,the tracking error rate based on the PIR sensor is relatively higher in the real environment. For this point,this paper proposed a high accuracy hu-man tracking scheme that based on pyroelectric infrared( PIR) Sensor. Firstly,PIR sensors detect the infrared signal of the moving human in the sensing area and the characteristics of the infrared signal are extracted. Then,the geo-metric parameters of locating node and the detecting data are used for the preliminary positioning result. Finally, Kalman filter algorithm is used to filter the preliminary positioning result and update the target state information for realizing the human target positioning and tracking in the sensing area. Experiments show that the tracking error has decreased by 71.96% comparing with other similar tracking systems. It has been proved that the system has a high tracking accuracy.关键词
