Problems solved by technology

[0003] However, in the prior art, there is a lack of systems and methods that can reasonably detect the activity of seeds, especially for the activity detection of Pine massoniana seeds; the activity of Pine massoniana seeds affects the success rate of germination of Pine massoniana, which has always been an important part of forestry development. And attract people's attention, although the traditional see

Example Embodiment

[0046] Example 1

[0047] like figure 1 and figure 2 As shown, a multi-modal information fusion detection system for masson pine seeds includes a sealed air chamber box 1; plate 2, and on the camera frame fixing plate 2, a camera support rod 3 extending toward the center of the box body is installed. After the camera support rod 3 extends to a place, a focus-adjustable hyperspectral camera 4 is installed. The spectrum camera 4 is arranged at the center position of the upper end of the gas chamber box 1, and the shooting direction is aligned with the gas chamber box 1 below, and the bottom of the gas chamber box 1 is also supported by a system measuring plate 6 through the electronic scale 5 provided, In addition, a tuning fork carbon dioxide concentration sensor 7 is also installed in the air chamber box 1, and a full-spectrum lamp 8 coordinating with a focusing hyperspectral camera 4 is installed on both side walls of the air chamber box 1, and the air chamber box The fro...

Abstract

The invention discloses a pinus massoniana seed activity detection method based on multi-modal information fusion. The method comprises the following steps: detecting starch change in pinus massonianaseeds, detecting carbon dioxide concentration change in a pinus massoniana seed environment, fusing mass, volume and humidity information of the pinus massoniana seeds to establish a sample templateof seed activity, and comparing and updating the template to finally realize graded detection of the pinus massoniana seed activity. According to the method, information of multiple modes is fused toenter pinus massoniana seed recognition, and various activity indexes of the seeds are recorded while one-time measurement is carried out; multiple times of different tests in a traditional method areavoided, one-time quickness of masson pine seed activity detection is achieved, and time spent on the tests is greatly saved.

Description

technical field [0001] The invention relates to the technical field of standardized monitoring of seed vigor, breeding, seed processing and treatment process, in particular to a multimodal information fusion pine seed activity detection system and a detection method thereof. Background technique [0002] Seed vigor refers to the robustness of seeds, which is the sum of seed germination and emergence rate, seedling growth potential, plant stress resistance and production potential, and is an important indicator of seed quality. Low-quality seeds have a low germination rate in the field, resulting in serious economic losses. Therefore, the detection of seed vigor has become an important part of the development of agriculture and forestry. It directly affects agricultural production and natural environment and other livelihood issues; Accurate mastery, reasonable selection and precise application not only improve the efficiency of seed vigor determination, but also indirectly p...
