When selecting data source from the multi-sensor information sources for the traditional optoeletronic tracking devices, the modes of manual control or switching according to the priority are usually used.In order to overcome the hysteresis, randomness and step effect of the switching mechanism, a multi-source data fusion control strategy is proposed. First, the adaptive variable tracking gate is calculated for planning the related areas, and the outliers are eliminated.Thenthe hierarchical integration structure is designed according to the related areas.Finally, the membership function is used to calculate the fusion weighting factor. The practical application has showed that, this integration control strategy can improve the tracking accuracy, reduce the overshoot, and enhance the robustness and reliability.
