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...

Method used

The air chamber casing 1 is integrally set to be made of ultra-clear glass, and the sealing rubber ring that prevents gas leakage is provided at the sealing side cover 10; Roots are intersected at the middle position of the upper end of the gas chamber box body 1; the system measuring plate 6 is set to be made of lead-containing PVC material capable of absorbing a spectrum; and the central part of the system measuring plate 6 is printed with a side length of 20cm, The pure white frame line with a width of 1cm is used to delineate the seed placement area and facilitate the segmentation of subsequent hyperspectral images.
Utilize unique active template method of the present invention to set up the active template model of Pine massoniana seed, utilize the distance in high-dimensional space as the difference between weighing each template, and utilize the mode of successive iteration to generate template, make the measured The accuracy can be continuously improved, and the classification accuracy can be further upgraded by adding new samples; the present invention integrates the information of various modes into the identification of Pinus massoniana seeds, and records the activity indicators of the seeds at the same time of one measurement; Multiple different tests in the traditional method have achieved a one-time rapidity of the de...

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.

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 front end of the body 1 is also hingedly equipped with a sealing side cover 10 through a rotating shaft 9 .
[0048] The air chamber box body 1 is integrally set to be made of ultra-clear glass, and a sealing rubber ring to prevent gas leakage is arranged at the sealing side cover 10; The upper middle position of the air chamber box 1 intersects and is set; the system measuring plate 6 is set to be made of lead-containing PVC material capable of absorbing a spectrum; and the central part of the system measuring plate 6 is printed with a side length of 20cm and a width of 1cm The pure white frame line is used to delineate the seed placement area and facilitate the segmentation of subsequent hyperspectral images.
