Embodiment Construction

[0071] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present application can be more thoroughly understood, and the scope of the present application can be fully conveyed to those skilled in the art.

[0072] In the current UAV speed control solution, the following scheme is usually used, that is, two different speeds are adopted according to whether there is an obstacle in front. In the PX4 Avoidance (an open source flight control system developed by the Swiss PX4 team) system, the flight speed has two values, that is, the speed with obstacles and the speed without obstacles. When there is no obstacle in front...

Abstract

The invention discloses an unmanned aerial vehicle speed control method and device, an unmanned aerial vehicle and a storage medium. The method comprises the steps: carrying out multi-stage flight estimation according to the target speed and expected path of an unmanned aerial vehicle to sequentially obtain the first estimation position of the unmanned aerial vehicle at the end of each stage; after a first estimated position is obtained, determining the availability of the first estimated position according to then expected path and / or obstacle information, adjusting the target speed under thecondition that the first estimated position is not available, and carrying out multi-stage flight estimation again according to the adjusted target speed; and controlling the speed of the unmanned aerial vehicle according to the current target speed under the condition that the flight estimation termination condition is met. According to the unmanned aerial vehicle speed control method, the speedcontrol process of the unmanned aerial vehicle can be flexibly and meticulously processed, the most reasonable speed is autonomously planned according to obstacles and the real-time flight conditionof the unmanned aerial vehicle, and the flight safety and flight efficiency of the unmanned aerial vehicle are ensured.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, and specifically relates to a speed control method and device for an unmanned aerial vehicle, an unmanned aerial vehicle and a storage medium. Background technique [0002] In recent years, UAV technology has gradually developed in the direction of intelligence and automation. The autonomous distribution function of UAVs has also become a key project for some UAV R&D teams. The maturity of this function is the result of unmanned distribution in cities. prerequisite for large-scale application. [0003] However, the complex environment of the city and the complex requirements of the business put forward higher requirements for the autonomous distribution function. On the one hand, the autonomous distribution function must meet the safety requirements, and on the other hand, the autonomous distribution function must also meet the requirements of distribution efficiency. ...
