动态目标跟踪与自动特写快照系统的设计及实现
Design and realization of dynamic target tracking and automatic close-up snapshot
摘要
Abstract
The existing dynamic target tracking and snapshot system is difficult to meet the requirements of clear, reliable, real-time and accurate tracking capture simultaneously. To solve the problem , this paper proposes a new dynamic target tracking and snapshot system which is more practical and less complex. A fast mixture Gaussian background difference method is adopted to segment the moving object, and accurate target positioning is obtained by the project method. Besides, in order to achieve the purpose of dynamic tracking, the methods of Kalman filter and template matching are both applied by combining with the method of pan-tilt-zoom (PTZ) camera calibration. Meanwhile, in the PTZ tracking process, on the basis of the extreme value of gradient and the actual motion vector of the target, a method to realize the adaptive capture of clear snapshot of objectives is proposed. In VC + +environment, the human body is taken as the moving target for testing. The experimental results indicate that this system has realized the purpose of dynamic target tracking and snapshot, and also has advantages of real-time, clarity and robustness.关键词
