Automatic Control Method to Video Tracking System for a Flying Target

摘要

In this paper, an automatic control method is proposed for a two rotational degrees-of-freedom (DOF) video tracking system to track a flying object. An acoustic passive localization algorithm based on planar five-element array is adopted, to focus on the flying target when it first appears. The kinematic of the video tracking system is analysed. Then the interaction matrix based on the target centroid feature is derived for the target with irregular and complicated shape. Finally a predictive control approach is developed to facilitate an effective tracking. The experimental results show the effectiveness of the proposed control scheme.
