    Acquisition and processing software: SpecVIEW
    \nAcquisition function: exposure, gain, speed can be flexibly set, and real-time hyperspectral images and hyperspectral curves can be dynamically displayed; with the auxiliary camera, what you see is what you get; with automatic exposure, automatic speed matching, automatic data saving, and other functions; support any Three-band composite real-time display, image return; support one-key collection of black and white frames and large-area calibration target data collection; data storage formats are widely used, with commonly used data review and correction functions, and optimized fast correction and special correction algorithms.<\/p>\n

    Preprocessing functions: geometric correction, reflectivity correction, regional correction, radiometric correction, and other functions; cluster analysis, single-band, true and false color, more than 20 kinds of vegetation indices (can be customized) can be obtained with one key without third-party software, Image 3D cropping, target spectral recognition, and other images, all of the above functions can realize unattended batch processing. It can automatically use the GPS information and flight attitude data obtained by GPS and inertial navigation systems to perform automatic geometric correction of hyperspectral images, and can significantly eliminate image distortion caused by the motion of airborne platforms such as drones, and the processed images will not be distorted. There should be an obvious band dislocation phenomenon; it can effectively and automatically splice the corrected band data, and the splicing result does not contain an obvious dislocation phenomenon; it provides the function of radiometric calibration for all bands.<\/p>\n

    1. Agriculture application; rapid identification and classification of crops.<\/strong>
    \nWhen there is more than one crop, rapid classification and identification is very important, because different crops have different types and amounts of fertilizers, and fertilizing only according to the growth map may result in some crops being over-fertilized and others under-fertilized. Compared with the multi-spectral system, the UAV hyperspectral system has more spectral bands and higher spectral resolution, so it can obtain different responses of different crops in different wavelength bands, so as to achieve fast and effective identification. Its recognition rate can be as high as 95%.<\/p>\n

    2. Analysis of soil water content and soil fertility.
    \nThe DJI M300 drone hyperspectral camera can obtain the distribution map of soil moisture content, soil total fertility content, and organic matter content during its hyperspectral image acquisition process. According to the distribution map of soil moisture content and soil fertility, farmers can quantitatively irrigate and fertilize, so as to solve expenses and avoid environmental pollution.<\/p>\n

    3. Tree species classification, monitoring tree height
    \nConsidering the confidentiality of user scientific research data, this study only uses single-scene hyperspectral image data to classify and identify different tree species. The classification and identification results are shown below. In order to use the best index method to extract the characteristic bands and use the see5.0 machine learning rule software to classify the tree species, the user can use the multiple sets of data obtained by the UAV hyperspectral camera to splice, and then classify the tree species. The steps and algorithms are the same.<\/p>\n
