Hyperspectral technology-based non-destructive testing device for diagnosing nutrition conditions of crops

Abstract

The invention discloses a hyperspectral technology-based non-destructive testing device for diagnosing the nutrition conditions of crops. The non-destructive testing device comprises a base, wherein adark box is put on the base; the top of the dark box is hinged with a box cover; a through groove is transversely formed in the box cover; a movable illumination assembly is arranged in the dark box;support plates are fixedly connected with four corners at the top of the base; the upper parts of two groups of support plates at the left side and the right side are fixedly connected with connection plates; a sliding assembly is arranged between two groups of connection plates; the bottom of the sliding assembly is connected with a hydraulic telescopic rod; a telescopic end of the hydraulic telescopic rod is fixedly connected with an angle adjusting assembly; the angle adjusting assembly is connected with a hyperspectral imager; the hyperspectral imager is electrically connected with a computer; and a control panel is arranged on the base. The movable illumination assembly is arranged in the dark box, so that adjustment of an illuminating lamp is facilitated, meanwhile, the transverse position of the hyperspectral imager can be adjusted through the sliding assembly, and the angle of the hyperspectral imager can be adjusted through the angle adjusting assembly, so that operation is very convenient.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of crops, in particular to a non-destructive detection device for diagnosing the nutritional status of crops based on hyperspectral technology. Background technique [0002] Hyperspectral imaging technology is based on very narrow-band image data technology. It combines imaging technology with spectral technology to detect the two-dimensional geometric space and one-dimensional spectral information of the target, and obtain continuous and narrow-band images with high spectral resolution. data. The research on the application of hyperspectral technology in agriculture, especially precision agriculture, has received strong support from the national science and technology department. The nutritional status of crops can be detected non-destructively through hyperspectral imaging technology.

AI Technical Summary

Problems solved by technology

[0003] When the existing device detects the crops, the crops are generally put into the dark box for detection, but in the existing equipment, the position of the light in the dark box cannot be adjusted, which often leads to inaccurate detection results. Moreover, it is very troublesome to adjust the position and angle of the hyperspectral imager. The adjustment steps are relatively cumbersome. The efficiency of non-destructive inspection of crops is low, and the inspection is very inconvenient.
