Automatic white board storing and fetching apparatus for correction of field spectral imaging system

Abstract

The invention discloses an automatic white board storing and fetching apparatus for correction of a field spectral imaging system. The apparatus comprises a supporting platform; an elevating platform, which is located above the supporting platform; an elevation driving mechanism, which is mounted on the supporting platform to drive the elevating platform to move up and down; a white board box, which is arranged on the elevating platform and provided with a box door; a white board supporting member, which is located in the white board box and used for fixing a white board; and a telescoping driving mechanism, which is installed in the white board box and used for driving the white board supporting member to enter and exit from the box door; wherein the elevation driving mechanism comprises a vertical screw installed on the supporting platform in a rotary way, a thread bush fixed on the elevating platform and matched with the screw, a gear shaft horizontally installed on the supporting platform, an elevating motor in linkage with the gear shaft, and a first bevel gear and a second bevel gear which are respectively mounted on the gear shaft and the vertical screw and matched with each other. The apparatus provided by the invention more reliably guarantees accuracy of information acquired in later experimental process.

Description

technical field [0001] The invention relates to the fields of spectrum technology and farmland information detection, in particular to an automatic access whiteboard device for calibration of a field spectrum imaging system. Background technique [0002] Precision agriculture needs to carry out precise operations according to the growth status of crops and the conditions of the growing environment, so it is particularly critical to accurately collect field crop information. The acquisition technology of crop growth information is one of the important technical supports of precision agriculture. The technology of plant growth information acquisition mainly includes the use of its electrical characteristics, optical characteristics and machine vision technology. [0003] With the development of spectral technology, near-infrared spectroscopy, multi-spectral technology and hyperspectral technology have been widely used in the acquisition of crop growth information, and have sho...

Problems solved by technology

[0006] In order to eliminate the dark current in the lens and the noise caused by the uneven intensity of the light source, we need to correct the black and white of the field spectral image, and there is a big problem in the collection of the whiteboard in this process, and in order to ensure the cleanliness of the whiteboard, It is very inconvenient to put it in a closed box in the field or directly on a tractor and other agricultural machinery after each experiment
