A planning method for unmanned aerial vehicle aerial photography operations

Abstract

The invention discloses a planning method for unmanned aerial vehicle aerial photography operations. Under the constraints of the real overlap rate, the method iteratively adjusts the route and the position of the exposure point to obtain a more optimized and reliable exposure point, generates a flight plan according to the exposure point, and communicates After the flight control system receives the flight plan, it will execute the aerial photography task according to the position of the exposure point in the plan. The present invention designs a convergent iterative adjustment algorithm and DEM elevation query technology by considering terrain fluctuations and DEM under the constraints of the real overlap rate, which can realize self-adaptation and optimal adjustment of air routes and exposure point positions, and guarantee The aerial photography plan is more in line with expectations, and the aerial survey quality and aerial photography operation efficiency are improved.

Description

technical field [0001] The invention relates to the field of low-altitude digital photogrammetry, in particular to a planning method for aerial photography operations of unmanned aerial vehicles. Background technique [0002] As an important means of modern remote sensing surveying and mapping technology, UAV aerial photography is playing an increasingly important role in surveying and mapping work due to its advantages of flexibility and rapid deployment. Important content, its accuracy, degree of automation and design speed will directly affect the quality and benefits of aerial photography; the main work of aerial photography task planning requires the completion of aerial photography divisions, optimization and adjustment of routes, laying of exposure points, and the design results Send it to the flight control system of the UAV in a certain format, and the UAV will complete the aerial photography task. Obviously, the quality of the design results such as the division o...
