METHOD AND SYSTEM FOR TRACKING MOVING TRAJECTORY BASED ON HUMAN FEATURES

摘要

The present invention discloses a method and system for tracking a moving trajectory based on human features. The method comprises: simultaneously capturing images by a zooming CCD camera and an infrared thermal imager, and respectively transmitting the images to an intelligent analysis unit A and an intelligent analysis unit B; extracting and matching blocking features by a human feature identifying module of the intelligent analysis unit A, and detecting a target moving human body by a moving object detecting module; detecting a human boundary by the intelligent analysis unit B; obtaining analysis data in real time by a main control unit, computing the proportion of the size of the target moving human body in the size of the whole image, and a deviation angle and direction of a moving target and an optical axis, and transmitting the same to a cloud terrace control unit; and controlling the horizontal angle of a cloud terrace system, the vertical angle of the cloud terrace system and the focal distance of the zooming CCD camera by the cloud terrace control unit so that the moving target is always in the middle of the visual field of the zooming CCD camera. The present invention is not affected by the factors of weather, illumination, shadows and the like, and has lower probability of missing detection and false detection.
