An imaging method for a scanning imaging system based on a rotary-wing unmanned aerial vehicle

Abstract

The invention belongs to the technical field of scanning and imaging systems of unmanned aerial vehicles, and discloses an imaging method based on the scanning and imaging system of unmanned aerial vehicles, which is used to solve the problem of poor image acquisition quality caused by unsteady flight of unmanned aerial vehicles in the prior art . The scanning imaging system based on the rotor drone of the present invention includes a drone and a control module for controlling the flight of the drone. It is characterized in that the drone is connected with a scanning imaging system through a three-axis brushless cloud platform; The imaging method of the scanning imaging system of the UAV is: (1), the UAV is hovered to the target area through the control module; (2), the rotation of the scanning imaging system is controlled by the rotation of the three-axis brushless cloud platform to achieve alignment The scanning of the target area is realized by the rotation of the scanning imaging system itself.

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...
