Fixed-wing unmanned aerial vehicle for surveying and mapping

Abstract

The invention discloses a fixed-wing unmanned aerial vehicle for surveying and mapping, which comprises a front vehicle body, a shape-preserving surveying and mapping pod, a vehicle body deformation device, a rear vehicle body, a connection rotating device, a rear wing, a semi-rigid transition wing section and a bendable dish-shaped polyhedral frame, the shape-preserving surveying and mapping pod is arranged at the bottom of the front vehicle body, and the vehicle body deformation device is arranged at the rear part of the front vehicle body; the invention relates to the technical field of engineering surveying and mapping. According to the fixed-wing unmanned aerial vehicle for surveying and mapping, a variable connecting wing pneumatic layout and a rear power and front three-point type shape correction undercarriage layout are adopted, and the problems that an unmanned aerial vehicle with a high aspect ratio is difficult to execute aerial survey tasks in weather with large wind power and an unmanned aerial vehicle with a small aspect ratio is difficult to economically execute aerial survey tasks at a low flight speed can be solved; the unmanned aerial vehicle executes an aerial survey task in the mode of the minimum sweepforward angle and the maximum aspect ratio so as to prolong the space time and improve the use economy, and when the low-altitude wind power is increased, the unmanned aerial vehicle continues to work in the mode of the small aspect ratio.

Description

technical field [0001] The invention relates to the technical field of engineering surveying and mapping, in particular to a fixed-wing unmanned aerial vehicle for surveying and mapping. Background technique [0002] UAV aerial survey is a powerful supplement to traditional aerial photogrammetry. It has the characteristics of flexible maneuverability, high efficiency and speed, precision and accuracy, low operating cost, wide application range, and short production cycle. It has obvious advantages in terms of acquisition. With the development of UAV and digital camera technology, digital aerial photography technology based on UAV platform has shown its unique advantages. UAV aerial photography can be widely used in major national engineering construction, disaster Emergency response and treatment, land supervision, resource development, construction of new countryside and small towns, etc., especially in basic surveying and mapping, land resource survey and monitoring, land ...
