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 3D laser scanning system shown in this paper 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 si...

Abstract

The invention provides a comprehensive growth detection method and device for potted lettuce, wherein a comprehensive growth detection device for potted lettuce is composed of a polarization-hyperspectral imaging system and a three-dimensional laser scanning system, wherein the polarization-hyperspectral imaging system includes a control system , two-coordinate sample table, image acquisition system, and light source system can realize the detection of polarization-hyperspectral multi-dimensional reflection imaging characteristics of canopy / leaf scale of lettuce water and fertilizer stress; among them, the three-dimensional laser scanning system can realize lettuce biomass, stem Accurate detection of morphological characteristics such as girth, plant height, and leaf area. The invention realizes the accurate detection of the comprehensive growth information of the lettuce through the multi-information fusion of the growth characteristics of the canopy and the leaves at different scales, and provides a scientific basis for the optimization and regulation of the greenhouse environment and water and fertilizer.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture biological information detection, and relates to a method and a device for comprehensive growth monitoring of 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-destr...
