Research of indoor mobile biological air purifier pedestrian tracking system

With the progress of modern society and the environment pollution pricking up, people's requirement of quality of life is increasingly improved. Mobile biological air purifier can track pedestrians, adsorb and decompose or transform various air pollutants around pedestrian environment, improve air quality, has energy saving, environmental protection and beauty, give full play to the purifying effect, has a strong applicability. In the paper, according to the three-dimensional measurement principle of binocular vision, tracking system has been established, which has adopted Harr + Adaboost algorithm with CamShift algorithm to realize detection and tracking of pedestrian and mobile biological air purifier filter respectively, and adopted the Kalman filter to predict the next position to improve the effect of purifier detection and tracking. The experimental results show that the system can realize mobile biological air purifier tracking pedestrians accurately, in real time, under the target occlusion, fast moving, and so on.
