In view of the future intelligentization of unmanned systems and the need for collaborative perception and cognitive development of multiple unmanned systems, there is an urgent need to solve the scientific problems of information overload and cross-platform multi-source perception information fusion. This paper proposes to study bionic endogenous and exogenous The regulation mechanism of force, explore the regulation mechanism of multi-source attention mechanism on the intelligent perception system of unmanned systems, and study the mechanism of its mapping heterogeneous multi-source perceptions and behavior decision control. Combined with the use of brain cognition, it can combine clues from different sensory channels to achieve rapid and efficient information filtering and heterogeneous multi-source cognition of objects and events in the external world, and use different reference systems to represent the features and positions of objects to construct a This intelligent perception and information processing framework based on the bionic multi-source attention mechanism has a certain design reference value for the engineering realization of the intelligent perception and cognitive system of unmanned systems.
