Abstract

The invention provides an unmanned aerial vehicle orthoimage processing method and system, and the method comprises the steps: setting image control points in a first target region based on a plurality of image control point setting schemes; based on various image control point setting schemes, acquiring a plurality of aerial photo image sets of the first target area by adopting an unmanned aerial vehicle; a plurality of aerial photo image sets are adopted, and a plurality of orthoimages are obtained through synthesis; calculating a plurality of area areas of the first target area according to the plurality of orthoimages; performing global optimization in the plurality of image control point setting schemes according to the plurality of region areas to obtain an optimal image control point setting scheme; and taking the orthoimage corresponding to the optimal image control point setting scheme as a first orthoimage of the first target area.

Description

technical field [0001] The invention relates to the technical field of aerial image processing, in particular to a method and system for processing orthophoto images of unmanned aerial vehicles. Background technique [0002] UAV has become an important tool in low-altitude remote sensing surveying and mapping because of its ability to operate in complex terrain, flexible remote sensing, and low cost, and is widely used in surveying and mapping of complex terrain. [0003] At present, drones are used for remote sensing mapping, generally by setting image control points in the target area, and then using drones to collect field images of the target area under appropriate conditions, and then targeting based on the system algorithm built into the drone. Office processing synthesis of area 3D models and orthophotos. [0004] In the prior art, due to the angle, remote control point setting and other factors in the aerial survey and shooting process of the UAV, the orthophoto ima...
