Real-time ranging and positioning system for unmanned aerial vehicle

Abstract

The invention provides a real-time ranging and positioning system for an unmanned aerial vehicle. The system comprises a distance measuring module, a numerical comparison circuit, an inertial navigation system and a data storage module. Position information between the unmanned aerial vehicle and the environment is obtained through the distance measuring module; whether the position information acquired by the distance measurement module has an overlarge error is detected through the numerical value comparison circuit, the accuracy of the position information is improved, the state informationof the unmanned aerial vehicle is acquired through the inertial navigation system, and the real-time position information and the state information of the unmanned aerial vehicle are stored in the data storage module. According to the real-time ranging and positioning system for the unmanned aerial vehicle, a multi-sensor fusion mode is adopted, and real-time and rapid unmanned aerial vehicle related information can be obtained in various scenes.

Description

technical field [0001] The invention belongs to the field of drone control, and in particular relates to a real-time ranging and positioning system for drones. Background technique [0002] With the rapid development of economy and society and the rapid development of science and technology, UAV technology has developed rapidly. UAVs need to obtain their coordinate information, status information, etc. in real time during flight to ensure the normal and safe flight of UAVs. Therefore, there is an urgent need for a real-time ranging and positioning technology for UAVs. [0003] UAVs have the characteristics of small size, strong mobility, flexible operation, and low cost, and can perform tasks in dangerous and complex environments. Therefore, in recent years, they have been widely used in military and civilian fields such as reconnaissance, disaster relief, and environmental detection. . How to realize the positioning of UAVs in complex indoor environments (such as high-ris...
