Problems solved by technology

Large fixed-wing UAVs are mostly gasoline-powered aircraft, which are not safe to operate in urban areas
Multi-rotor UAVs have high safety, but low efficiency. Generally, they are equipped with five QX1 lens cameras, and the image quality is poor.

Abstract

The invention discloses a flight-line design method with single-lens oblique photography, a system and an aerial photography method. The flight-line design method comprises the following steps: obtaining the aerial range and the technical requirements; installing a single-lens camera, calculating aerial parameters, and carrying out flight-line design according to the aerial parameters. The flight-line design method, the system and the aerial photography method disclosed by the invention can be used for popularizing oblique photography of an unmanned aerial vehicle, and have the advantages that the threshold of the oblique photography is lowered and the efficiency of the oblique photography of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention relates to the field of aerial photogrammetry, in particular to a single-lens oblique photography aerial flight route design method, system and aerial photography method. Background technique [0002] Oblique photography technology is a high-tech developed in the field of international surveying and mapping in recent years. It overturns the previous limitation that orthophotos can only be taken from a vertical angle. Collect images from five different angles including four tilts. [0003] In recent years, the drone industry has developed rapidly, especially light and small drones, which are widely used in aerial photography, surveying and mapping, agricultural plant protection, power inspection, disaster relief, news reports and other fields. At present, the mainstream of oblique photography is to use manned drones, large fixed-wing drones, and multi-rotor drones equipped with 5 cameras. The efficiency of manned aircraft is high, and it...
