Problems solved by technology

However, with the cost reduction, miniaturization, intelligence, and civilianization of drones, the cost of drones and cameras is further reduced. Even if quasi-professional or even consumer-grade cameras and lenses are used, most of the camera’s internal parameters have not been strictly calibrated. , and at this time, when directly using the captured orthophoto images for mapping, there will be systematic deviations in the elevation
The traditional aerial survey method is to ensure the accuracy of the final map by drawing a large number of ground control points, but the operation process is time-consuming and labor-intensive and the cost is high

Abstract

An aerial survey method, comprising: controlling a shooting device of an aircraft to shoot an orthophoto (S101); obtaining flight information corresponding to the orthophoto taken by the aircraft, and determining the flight height, flight radius and center of rotation of the aircraft obliquely taken according to the flight information (S102 ); control the flight of the aircraft and the orientation of the photographing device according to the flight height, flight radius and center of orbit to shoot oblique images (S103). It also relates to an aircraft and a storage medium. This method can improve the accuracy of mapping.

Description

technical field [0001] The present application relates to the field of aerial survey technology, and in particular to an aerial survey method, an aircraft and a storage medium. Background technique [0002] At present, in the application field of UAV surveying and mapping, the most widely used application is orthophoto shooting, which is used for digital orthophoto map (Digital Orthophoto Map, DOM) / Digital Elevation Model (Digital Elevation Model, DEM) reconstruction. However, with the cost reduction, miniaturization, intelligence and civilianization of drones, the cost of drones and cameras is further reduced. Even if quasi-professional or even consumer-grade cameras and lenses are used, most of the camera’s internal parameters have not been strictly calibrated. , and at this time, when directly using the captured orthophoto images for mapping, there will be systematic deviations in elevation. The traditional aerial survey method guarantees the accuracy of the final map by...
