Unmanned aerial vehicle autonomous take-off and landing cruising method based on digital twinning

Abstract

The invention discloses an unmanned aerial vehicle autonomous take-off and landing cruising method based on digital twinning. The method is created on an informatization platform, so that an unmanned aerial vehicle completes autonomous take-off and landing under the condition that detection and positioning cannot be realized. A big data cloud platform is introduced to carry out online optimization on an established scene model, and the Internet of Things is introduced for service online upgrading, so that real-time efficient real-time interaction between unmanned aerial vehicle information in reality and an unmanned aerial vehicle in a virtual scene is realized; the core problems that the unmanned aerial vehicle is low in informatization degree, data acquisition is delayed, decision making is carried out excessively depending on flight experience of a manipulator and the like are solved, high-precision man-machine interaction is achieved, information processing is carried out through multi-sensor fusion, remote high-precision unmanned aerial vehicle information processing is achieved, the calculation amount of the unmanned aerial vehicle is reduced, and the unmanned aerial vehicle is safer and more efficient.

Description

technical field [0001] The invention relates to digital twin technology, in particular to a digital twin-based autonomous take-off and landing cruising method for unmanned aerial vehicles. Background technique [0002] With the progress of the times and the development of science and technology, drones are widely used in various fields. At the same time, emerging digital twin technologies are gradually flooding people's lives. Digital twins make full use of data such as physical models, sensor updates, and operating history. Integrate the multi-disciplinary, multi-physical, multi-scale, and multi-probability simulation process, and complete the mapping in the virtual space to reflect the entire life cycle process of the corresponding physical equipment. A digital twin is a concept beyond reality that can be viewed as a digital twin of one or more important, interdependent equipment systems. Digital twin is a generally applicable theoretical and technical system that can be ...

Problems solved by technology

[0004] At present, with the development of control technology, many excellent algorithms are applied to the autonomous take-off and landing of UAVs, and very good results have been achieved in the experimental verification, but these are the autonomous take-off and landing of UAVs in real environments. Although cruising greatly reduces the need for manpower and material resources, it still cannot meet the current needs for complex terrain and bad weather. There are great hidden dangers in its safety and efficiency. It is difficult to use for some relatively small and complex geographical environments.

[0005] Secondly, although the further development of algorithms in recent years, the application of SLAM technology, and the development of robust control filtering have significantly improved the control effect of UAVs, but for environmental strains, object recognition, and UAVs to withstand a large number of calculation, it has big problems in autonomous take-off and landing, and fixed-point cruise
