A surveying and mapping method for rapid surveying and mapping of multi-rotor UAVs

Abstract

The invention discloses a multi-rotor unmanned aerial vehicle for fast surveying and a surveying method of the multi-rotor unmanned aerial vehicle, and belongs to the technical field of aviation surveying. The multi-rotor unmanned aerial vehicle comprises a rack, flight lifting mechanisms, a cloud deck mechanism and a control mechanism, wherein four plane arms extend out from the rack along a plane body, the lower part of the plane body is provided with foot stools, the plane arms and the foot stools are of foldable structures; and the flight lifting mechanisms are arranged at tail ends of the four plane arms, the cloud deck mechanism is mounted at the bottom of the unmanned aerial vehicle body through a mounting rod; the cloud deck mechanism is provided with a camera and is used for regulating an optical axis of the camera to be always perpendicular to the ground; and the control mechanism is used for controlling the unmanned aerial vehicle to fly to the appointed height and regulating the overturn of the cloud deck mechanism. The surveying method disclosed by the invention can be used for determining the relation between the shooting height and the imaging proportion by analyzing camera lens parameters, and then setting the flight line of the unmanned aerial vehicle. Through the adoption of the unmanned aerial vehicle, the surveying result can be fast obtained, and the surveying precision and efficiency are high.

Description

technical field [0001] The invention relates to the technical field of aerial surveying and mapping, and more specifically, relates to a surveying and mapping method for rapid surveying and mapping of multi-rotor UAVs. Background technique [0002] With the rapid development of electronic technology, small drones have made significant breakthroughs in remote control, battery life, and flight quality. They have become a new aerial remote sensing method that has emerged in recent years, and are generally considered by the remote sensing community to have good development. prospect. However, the vast majority of UAVs currently in use are not designed for the surveying, mapping and remote sensing industry. Although a simple model airplane also has a flight control system, it can also realize automatic driving and continuous photography in the air. However, during the flight operation, because the UAV is easily affected by the airflow, it will produce irregular attitude changes ...
