Abstract

The application, which relates to the technical field of unmanned aerial vehicles, provides a multispectral imaging system and method. The multispectral imaging system comprises a controller, a multi-view camera, an illumination sensor and a digital processor, wherein the multi-view camera, the illumination sensor and the digital processor are electrically connected with the controller. The controller is used for controlling the multi-view camera to shoot a target plot when an unmanned aerial vehicle flies to a set shooting point to obtain a plurality of spectral images; the illumination sensor is used for measuring an illumination intensity value of each preset waveband; and the digital processor is used for performing radiation correction on each spectral image according to the illumination intensity value of each preset waveband to obtain a plurality of reflectivity images, acquiring a target reflectivity image corresponding to a vegetation index from the plurality of reflectivity images according to the vegetation index, and performing index calculation to obtain a vegetation index map. According to the application, the vegetation index map reflecting the plant information in the target plot can be automatically generated without manual participation, so that human resources are saved, and the detection efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular, to a multi-spectral imaging system and method. Background technique [0002] With the rapid development of the drone industry, the application of drones in agriculture is becoming more and more extensive. UAV remote sensing system has been widely used in professional fields such as farmland drug spraying, farmland information monitoring, and agricultural insurance survey due to its advantages of convenient transportation, high flexibility, and short operation cycle. [0003] Existing spectral remote sensing technology usually uses drones equipped with multispectral sensors to detect the spectral information of crops to obtain multispectral data, and then professionals conduct subsequent analysis and processing of the data to obtain plant information. The whole process requires a lot of manpower. Contents of the invention [0004] The purpose of this ap...
