Abstract:With the discovery of navigation cells in animal brain and the rapid development of artificial intelligence, brain-like SLAM autonomous navigation method inspired by animals provides a new idea to break through the bottleneck of existing navigation methods. This paper reviews the research progress of brain-like SLAM autonomous navigation technology for the UAV, concluding: 1) discussing the research status of SLAM technology for the UAV; 2) introducing brain-like SLAM autonomous navigation scheme in the 3D space and single environment on the basis of the 2D SLAM navigation technology; 3) analyzing the key technologies of 2D and 3D brain-like SLAM autonomous navigation scheme; 4) finally analyzing and verifying the existing 3D navigation schemes, and pointing out the problems need to be solved in the brain-like SLAM application of the UAV. Brain-like SLAM does not rely on high-precision sensors, has strong adaptability to the environment and high autonomous intelligence, and is more suitable for the complex and dynamic flight environment of UAV.
