Abstract

Provided is a multi-angle observing system of aquatic vegetation canopy spectra. A servo motor is installed on a horizontal cross beam of a support frame, wherein an output shaft of the servo motor is arranged along the vertical direction, the output shaft of the servo motor is connected with a rigid semicircular track with an downward opening through an azimuth shaft and a track frame, and the track frame is connected with the midpoint of the track in a hinged mode; an observing hole which penetrates axially is formed in the track, a rack is installed on the outer wall of the track, and a fiber-optics probe trolley and a balance trolley are symmetrically distributed at two sides of the central line of the track to keep balance of the track; when the fiber-optics probe trolley operates to the position where a fiber-optics probe is aligned to the observing hole, and signals of aquatic plants are obtained; and the servo motor, the fiber-optics probe trolley, the balance trolley, a hall locating sensor, and a sensing piece are all connected with a central controller.

Description

technical field

[0001] The invention belongs to an observation instrument for the canopy spectrum of aquatic plants. Background technique

[0002] Aquatic plants refer to plants that can grow normally in water or water-saturated soil for a long time, such as reeds, rice, mangroves, water shields, water lilies, etc. In order to grasp the growth of aquatic plants, such as the yield of rice, etc., it is necessary to observe them.

[0003] Since the wetland is covered by water all the year round or periodically, the radiation received by the remote sensor includes reflected light from the water surface, reflected light from suspended objects, reflected light from the bottom of the water, and reflected light from the sky (see image 3 ). Therefore, due to the influence of the water body background (water body, suspended matter, bottom material), the accuracy of aquatic vegetation classification and inversion is reduced, thereby reducing the accuracy of observation.
