Abstract: In recent years, the technology of video surveillance, widely used in the field of spaceflight,
has become an important technical means in spaceflight safety and management. This paper gives a
method to firstly detects change region of moving targets through background subtraction and temporal
difference. Detect moving targets through binarization and morphological filtering, thus moving targets
are identified combining with gray and textural features. Then Mean-Shift method to recognize and
track moving targets is adopted. Lastly an experiment video example to monitor is given. The result
shows that the feature of target has achieved good effect in the process of recognition. For the tracking
of spaceflight moving target the method has better robustness, and is feasible.

Key words: target detection, tracking, recognition, Mean-Shif t
