Abstract:Due to limitations of the access cycle, traditional means of satellite remote sensing is difficult to ensure the timeliness of data in time frequency. The low-altitude UnmannedAerialVehicle(UAV) equipped with a small light sensor, its maneuvers, rapid, economic and other advantages play an increasingly important role in the field of environmental monitoring. In order to meet monitoring requirements of cyanobacteria in TaihuLake, a visible-near infrared sensor monitoring method has been found based on the low-altitude UAV. On the basis of system planning and design platform, selecting Meiliang Lake area of Taihu lake to carry out the experiment. Based on previous experiences, using the Visible and Near Infrared Bands, and its combination, cyanobacteria linformation can be extracted, and verified with the experimental data. The method can provide auxiliary means and decision support for preventing and managing cyanobacteria disaster.
