Abstract

The invention relates to the technical field of spectral image imaging, and discloses a spectral image imaging device for detecting the content of nitrogen, phosphorus and potassium in agricultural product leaves, the spectral image imaging device comprises a base, the left side of the upper end of the base is provided with a computer, the upper side of the base is connected with a light box, and the inner wall of the light box is provided with an adjusting device; the lower side of the adjusting device is connected with a lamp, a camera element is installed on the upper side wall of the upper side wall of an inner cavity of the light box, an image adapter is installed on the lower side of the camera element, the adjusting device comprises two sets of first electric rails, and the moving ends of the two sets of first electric rails are connected with second electric rails; third electric rails are connected to the moving ends of the two second electric rails, and a mounting plate is mounted at the moving ends of the third electric rails. According to the scheme, the position of the lamp can be adjusted by arranging the adjusting device, the application range of the lamp is widened, and cooperation of the lamp with a spectral imaging test is improved.

Description

technical field [0001] The invention belongs to the technical field of spectral image imaging, in particular to a spectral image imaging device for detecting the nitrogen, phosphorus and potassium content of leaves of agricultural products. Background technique [0002] Agricultural products (English name: farm produce) are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties in various regions. The state stipulates that primary agricultural products refer to plants, animals and their products obtained in agricultural activities, excluding processed products. [0003] Litchi agricultural products, also known as Lizhi, belong to the evergreen tree of the genus Litchi in Sapindaceae. [1] Together with bananas, pineapples, and longan, they are known as the "four major fruits in the southern country". Bright red, the flesh is translucent and creamy when fresh, delicious in taste, but not resistant to storage. It is distributed in the...

Problems solved by technology

[0004] Nitrogen, phosphorus, and potassium are among the various nutrient elements (carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, and magnesium) that plants need. Nitrogen, phosphorus, and potassium are the nutrients that plants require and take away more during harvest. Over the past few years, some scholars at home and abroad have mainly applied hyperspectral image technology to the detection of agricultural product quality and crop diseases. Polarization spectrum technology has been used to invert the content of chlorophyll in plant leaves, but no polarization-hyperspectral technology has been used to diagnose crops. Due to nutritional deficiencies of nitrogen, phosphorus, and potassium, most scholars need to adjust the lamps when observing litchi leaves. Therefore, we propose a spectral image imaging device for detecting nitrogen, phosphorus, and potassium content in leaves of agricultural products.
