Abstract

The present invention is suitable for the unmanned aerial vehicle technology field, and provides an unmanned aerial vehicle height control method and system. A plurality of narrow beam single point measurement sensors are employed to perform distance measurement, and measurement results of a plurality of sensors are subjected to weight processing to allow the measurement results to be more accurate. In the calculation, the unmanned aerial vehicle height control method and system fuse the posture data of an unmanned aerial vehicle and perform dynamic posture measurement compensation processing of the measurement results. Compared to the prior art, the unmanned aerial vehicle can realize rapid following of the topography, keep the height and effectively avoid barriers above the unmanned aerial vehicle. The cost is low, the power consumption is small, the application scenes are various, flight effects are good, and the product viscosity is improved.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a method and system for controlling the height of an unmanned aerial vehicle. Background technique [0002] The current research on UAV technology mainly focuses on how to improve the flight capability of UAV, so that it can cope with different flight environments, and can carry out adaptive flight in complex environments, and complete the target tasks safely and stably. In recent years, with the continuous application of various new technologies, the complexity of UAV systems and the degree of automation of functions are increasing. However, due to the highly dynamic and uncertain flight environment and the complexity of flight tasks, UAVs are facing new technical challenges in planning and decision-making. The multi-tasking requirements of multi-functional UAVs in complex flight environments, and the improvement of autonomous flight control capabil...
