Abstract: This paper deals with the parallel object recognition of the information reconnaissance and data fusion systems, analyses its feasibility, provides a strategy of partitioning based on tracks, designs and implements the parallel object recognition center based on the message passing interface with a dynamic load balancing technology. While a predigested form of the dempster-shafer theory of evidence under some special situations is presented and how to use it is told. Finally, it gives the results of the performance test to the parallel object recognition center. It can be seen that the speed of recognition is improved while ensuring the reliability of the recognition, which solves the key performance problem of the fusion system.
