Imaging method for rotor wing unmanned aerial vehicle-based scanning imaging system

Abstract

The invention belongs to the technical field of rotor wing unmanned aerial vehicle-based scanning imaging systems, and discloses an imaging method for a rotor wing unmanned aerial vehicle-based scanning imaging system. The imaging method can be used for solving the problem that an unmanned aerial vehicle is unstable to fly, so that the image collection quality is poor in the prior art. The rotor wing unmanned aerial vehicle-based scanning imaging system comprises an unmanned aerial vehicle and a control module for controlling the flying of the unmanned aerial vehicle, and is characterized in that the unmanned aerial vehicle is connected with a scanning imaging system by a three-shaft brushless cloud platform. The imaging method comprises the steps: (1) hovering the unmanned aerial vehicle to a target region by the control module; and (2) scanning the target region by controlling the scanning imaging system to rotate by rotation of the three-shaft brushless cloud platform or scanning the target region by the self rotation of the scanning imaging system.

Description

technical field [0001] The invention belongs to the technical field of hyperspectral imaging of a rotor UAV, and in particular relates to a scanning imaging system and an imaging method based on a rotor UAV. Background technique [0002] The development of remote sensing technology has gone through panchromatic (black and white), color photography, and multi-spectral scanning imaging stages. The imaging spectrum technology that appeared in the early 1980s brought optical remote sensing into a new stage—the stage of hyperspectral remote sensing. The so-called hyperspectral remote sensing refers to the remote sensing science and technology with high spectral resolution. The imaging spectrometer used in the imaging spectroscopy technology can acquire many very narrow and continuous spectrum in the ultraviolet, visible, near-infrared and short-wave infrared regions of the electromagnetic spectrum. image data. Imaging spectrometers provide each pixel with dozens to hundreds of n...
