Linear engineering surveying and mapping unmanned aerial vehicle

Abstract

According to the linear engineering surveying and mapping unmanned aerial vehicle, the bottom of an unmanned aerial vehicle body is connected with the top of a surveying and mapping main frame through a buffering connection compensation mechanism, and the buffering connection compensation mechanism has the elastic buffering capacity in the vertical direction; according to the surveying and mapping main frame, the buffering connection compensation mechanism can enable the surveying and mapping main frame to have the inclined rotation buffering recovery capacity at the connecting position of the surveying and mapping main frame and the buffering connection compensation mechanism, the buffering connection compensation mechanism is used for effectively reducing the mutual influence of control over the main propeller set and the auxiliary propeller set, and accurate control is achieved. The controller controls the main propeller set and the auxiliary propeller set to act at the same time for surveying and mapping, so that the main propeller set and the auxiliary propeller set are utilized to keep balance and stability of the unmanned aerial vehicle at the same time.

Description

technical field [0001] Specifically, the invention is a linear engineering surveying and mapping unmanned aerial vehicle, which relates to the related field of unmanned aerial vehicle surveying and mapping. Background technique [0002] At present, with the continuous development of UAV surveying and mapping technology, there are more and more applications of UAVs for linear engineering surveying and mapping. However, when drones are used for surveying and mapping, since the outside world is easily affected by wind direction, wind speed, etc., drones are vulnerable to the force of the wind during surveying and mapping, which will cause problems such as slight shaking of the drone, which will lead to unmanned The surveying and mapping images taken by the machine during surveying and mapping are not clear, the calibration of reference points is not accurate, and the accuracy of surveying and mapping boundaries is not high. In this regard, some surveying and mapping drones are...

Problems solved by technology

However, in this way, due to the fact that the compensating blades and the main blades driving the UAV are connected on a rigid UAV frame, this actually leads to the fact that the compensating blades and the driving UAV The main propeller blades of the aircraft fly have the same function and will affect each other. Since the same gyroscope is used for feedback control, it is difficult to carry out effective and precise control when controlling it, and because of this The effect of mutual influence leads to the problem of overcorrection in feedback control and adjustment, which makes it difficult to effectively ensure the smoothness and stability of UAV operation.
