Problems solved by technology

The abundance and deficiency of crop nutrition and water will directly lead to differences in its biomass, leaf area, stem diameter, plant height, leaf inclination angle, etc., so it can also be used as an effective feature for inversion of nutrition and water; traditional visual images can obtain plant The overall morphological characteristics, but the measurement accuracy is not high

Embodiment Construction

[0116] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0117] The present invention utilizes figure 1 The polarization-hyperspectral imaging system shown and figure 2 The shown 3D laser scanning system can collect water and fertilizer information of potted lettuce at leaf scale and canopy scale.

[0118] Such as figure 1 As shown, the polarization-hyperspectral image detection system includes a control system, a two-coordinate sample stage 2, an image acquisition system, and a light source system.

[0119]The image acquisition system includes two polarization-hyperspectral imaging systems 5, an image collector 8, a vertical arm 3 and a cantilever 4; the vertical arm 3 consists of a base 3-1, a vertical rod 3-2 with a lead screw and a second A slide block 3-3 is formed, the base 3-1 is fixed on the left side of the botto...

Abstract

The invention provides a method and device for monitoring comprehensive growth vigor of potted lettuces. The device comprises a polarization-high-spectral imaging system and a three-dimensional laserscanning system, wherein the polarization-high-spectral imaging system comprises a control system, a double-coordinate sample table, an image acquisition system and a light source system and detects the polarization-high-spectral multi-dimensional reflection imaging features of canopy / leaves scale of lettuces subjected to fertilization and water stress. The three-dimensional laser scanning systemcan realize accurate detection of morphology features such as biomass, the stem diameter, plant height, and leaf area of the lettuces. The multi-information fusion of the growth characteristics of thelettuces with different canopy / leaves scales is carried out to realize accurate detection of the comprehensive growth vigor information of the lettuces, and provide scientific basis for optimal regulation and control of the greenhouse environment and the water fertilizer.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture biological information detection, and relates to a comprehensive growth monitoring method and device for potted lettuce. Background technique [0002] At present, the environmental control equipment for solar greenhouses and steel-frame greenhouses used by greenhouses in my country, especially small and medium-sized farmers, is relatively poor. The control of water, fertilizer and environment mainly relies on traditional experience, or is regulated according to the set value, without considering the growth information and dynamic changes of crops. The process cannot be dynamically regulated according to the real needs of crops. Therefore, there is an urgent need to accurately monitor the growth, nutritional information and growth process of crops, judge the growth status of crops, and realize precise regulation based on crop growth requirements. [0003] At present, the non-destructiv...
