Abstract

The invention discloses an automatic spectrum measuring method and an automatic spectrum measuring device. The automatic spectrum measuring device comprises an unmanned automatic navigation ship, and a field spectrometer, an automatic spectrum measuring device and a main control system which are fixedly arranged on the unmanned automatic navigation ship, wherein one end of the automatic spectrum measuring device is fixedly arranged on one side of a ship body, the other end of the automatic spectrum measuring device is connected with the field spectrometer and the automatic spectrum measuring device is used for automatically realizing the multi-angle movement of the spectrum probe of the field spectrometer required for water body spectrum measurement; and the main control system is respectively and electrically connected with the unmanned automatic navigation ship, the field spectrometer and the automatic spectrum measuring device and is used for transmitting path information to the controller of the unmanned automatic navigation ship, controlling the movement of the automatic spectrum measuring device and controlling the measurement and the storage of the spectrometer. The automatic spectrum measuring device has the advantages that the coverage area is wider, the monitoring locations can be flexibly set, the energy is saved when the device is compared with a large ship, the initial cost is low, the entire process is fully automated, the spectrum data, the time, the position and the photos are synchronously obtained, the manmade errors are avoided and the measurement efficiency is improved.

Description

technical field [0001] The invention relates to the field of remote sensing ground measuring instruments, in particular to an automatic spectrum measurement method and device. Background technique [0002] For water body / water quality remote sensing measurement, the profile method is only suitable for water bodies with a water depth greater than 10 meters, and the instruments are expensive, and the deployment and operation are complicated. law measurement. In the process of water surface method measurement, water surface specular reflection, radiation of sky light, waves and solar flares are all important factors affecting measurement accuracy and data validity. In order to reduce the noise as much as possible and improve the measurement accuracy, NASA and the international water color SIMBIOS organization have carried out in-depth research on the measurement geometry and measurement methods on the water surface, and have given a relatively reasonable measurement method and...
