Method for programming aerophotographic operation of UAV

Abstract

The invention discloses a method for programming aerophotographic operation of UAV. The method comprises: under the constraint of a real overlapping ratio, performing iterative adjustment on a courseand positions of exposure points to obtain optimized reliable exposure points; generating a flight plan according to the exposure points; sending the flight plan to a flight control system of a UAV via communication; and after the flight control system receives the flight plan, performing an aerophotographic task according to positions of the exposure points in the plan. According to the method, under the constraint of a real overlapping ratio, topographic relief and DEM are taken into consideration, and a converging iterative adjustment algorithm and DEM elevation query technology are designed. Self-adaptive optimal adjustment of the course and positions of exposure points is achieved, the aerophotographic plan is guaranteed and accords with the expectation, and the aerial survey qualityand aerophotographic 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...
