| Abstract: | In this paper, a high frame frequence TV tracker is introduced. A new method, calculation of the gravity centre for a target and a compatible method with standard TV monitor for high frame frequence image display, are presented. In this system, the deviation between the position of object and the main optical axis of the TV tracker can be outputed in real-time with only time delay of 0. 1ms after end of frame scan. The bandwith of the TV tracker is 25HZ. The tracking error of a complex axis servo system using this TV tracker has been achieved 20 - 30" under the maximum vilocity of 20/s and the maximum acceleration of 20/s2. The results of experiment are presented in the last paragraph of this paper. |
