Challenges of Autonomous Navigation and Perception Technology for Unmanned Special Vehicles in Underground Mine

Autonomous navigation and perception technology in underground mine is an important basis for the development of “digital mine”. Traditional vehicle navigation and positioning methods have some problems, such as simple model, poor environmental adaptability and single information source, which cannot meet the requirements of high-precision autonomous navigation index in harsh environment in underground mine. By introducing the development history of navigation technology, this paper summarizes the development background of underground navigation and challenges faced by underground navigation at present. In this paper, the key points and difficulties faced by underground navigation are analyzed. The problems and development trend of underground navigation are discussed in combination with the sensors commonly used in autonomous high-precision navigation.
