Embodiment approach

[0047] As an implementation, after the environment consensus step, it also includes:

[0048] Active acquisition step: If an individual unmanned vehicle cannot obtain the environmental information required to complete the task, the blockchain-based block synchronization mechanism sends a request to the group to obtain environmental information from other individual unmanned vehicles.

[0049] As an implementation manner, the preset swarm intelligence optimization algorithm is one of ant colony algorithm, particle swarm algorithm and brainstorming algorithm.

[0050] Please refer to Figure 6 , the block chain-based collective unmanned vehicle cooperative perception system of the embodiment of the present invention includes an information exchange module, an environment consensus module and an active cooperative perception module.

[0051] Information exchange module: use the encrypted communication and block synchronization mechanism of blockchain technology to build a decent...

Abstract

The embodiment of the present invention discloses a block chain-based group unmanned vehicle cooperative sensing method, including: information exchange step: constructing a decentralized group unmanned vehicle information exchange and sharing network, to realize unmanned vehicles Information security exchange and sharing mechanism among them; environment consensus step: build a distributed perception information synthesis model based on dynamic Bayesian network, synthesize the distributed multi-source heterogeneous perception information of group unmanned vehicles, and eliminate environmental perception The inconsistency of the active collaborative sensing step: the active collaborative sensing task is modeled as a multi-objective optimization task, and the multi-objective optimization solution is performed on the active collaborative task, and the perception of a specific environment and a specific target is gradually completed. The embodiment of the present invention provides a reliable and accurate information basis for the optimal planning and decision-making of group unmanned vehicles by establishing a complete blockchain-based high-level collaborative sensing method and mechanism for group unmanned vehicles.

Description

technical field [0001] The present invention relates to the field of group unmanned driving, in particular to a method and system for cooperative perception of group unmanned vehicles based on blockchain. Background technique [0002] With the rapid development of theories and technologies such as deep learning, sensors, computers, the Internet, and the Internet of Things, an effective collaborative mechanism can enable each vehicle in a group of unmanned vehicles to have an environmental perception ability far beyond its own, and realize efficient monitoring of the environment. , comprehensive and accurate modeling, and to form consensus within the group. [0003] Group unmanned driving is an important direction for the development of unmanned driving in the future, and it is also an important technical way to break through the current limitations of unmanned vehicles. Collaborative sensing is one of the key scientific issues in swarm unmanned driving research. Obtaining a...
