Abstract

The invention provides a portable high-spectrum weed leaf herbicide identification optical device and method. The device comprises a first rectangular frame and a second rectangular frame. The first surface of the first rectangular frame and the second surface of the second rectangular frame are parallel. The first surface and the second surface form a detection slit. The first surface of the first rectangular frame and the second surface of the second rectangular frame are transparent glass surfaces. Other surfaces, except the first surface, of the first rectangular frame are light shieldingsurfaces. Other surfaces, except the first surface, of the first rectangular frame are light shielding surfaces. A hyperspectral camera is arranged at the position corresponding to a gap between firstand second soft light band sensors in the first rectangular frame. The hyperspectral camera is used for acquiring spectral information of weed leaves passing through the detection slit at a uniform rate through the first surface. The hyperspectral information of weed leaves realizes the identification of herbicides on weed leaves.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a portable hyperspectral optical device and method for identifying herbicides on weed blades. Background technique [0002] During the cultivation and planting of crops, the growth of weeds is very unfavorable to the growth of crops. Due to the strong growth ability and fast spreading speed of weeds, it seriously affects the absorption of sunlight and nutrients by crops. To solve this problem, weeds are usually removed by spraying herbicides. [0003] In practical application, in order to analyze the use effect of each herbicide, it is necessary to identify the weeds after spraying the herbicide to obtain the type and concentration of the herbicide on it, and then analyze the herbicide effect and optimal use of each herbicide concentration. However, in the prior art, there is no method for identifying herbicides on weeds. Contents of the invention [0004] Ai...
