[0028] A light intelligent compensation device for cultivating vegetable seedlings comprises a light cultivation box 1, a glass flip cover 101 is arranged on one side of the light cultivation box 1, the glass flip cover 101 is rotatably connected to the light cultivation box 1, a plurality of circulating water pipes 2 are arranged at both ends below the light cultivation box 1, a cultivation cabin 102 is arranged inside the light cultivation box 1, a box body back plate 103 is arranged on one side of the cultivation cabin 102, vegetable seedlings can be hydroponically cultivated through the cultivation cabin 102, and the glass flip cover 101 can effectively avoid the interference of external ambient light on the cultivation environment, thereby preventing the seedlings from growing unevenly.

The color group light strips 401 can adjust the color. The staff can judge the required light by observing the current growth stage of the vegetable seedlings, and then adjust the color group light strips 401 to the corresponding light color.

[0030] Specifically, a hydroponic rack 5 is provided inside the cultivation chamber 102, and the hydroponic rack 5 is connected to the light cultivation box 1 by screws. A planting plate rack 501 is provided above the hydroponic rack 5, and the planting plate rack 501 is connected to the hydroponic rack 5 by supporting legs 5011. The vegetable seedlings can be fixed above the hydroponic rack through the planting plate rack 501, so that the rhizomes at the bottom of the seedlings are in a suspended state.

[0031] Specifically, the outer surface of the planting plate frame 501 is provided with a plurality of brackets 5012, and the interior of the brackets 5012 is provided with a limit clamp 502. The interior of the hydroponic frame 5 is provided with a plurality of hydroponic tanks 504. Both ends of the circulating water pipe 2 extend to the interior of the hydroponic tank 504 respectively. The circulating water pipe 2 can inject nutrient solution into the interior of the hydroponic tank 504, and then the nutrient solution is extracted by the circulating water pipe 2 at the other end, and then re-input after filtering, so as to keep the interior of the hydroponic tank in a state of running water.

[0032] Specifically, a fan-shaped clamp plate 5021 is provided on the inner side of the limiting clamp 502, wherein gaps are provided between the fan-shaped clamp plates 5021, and a photosensitive component 503 is provided between the limiting clamps 502. The photosensitive component 503 can sense the current light intensity to determine whether the surrounding seedlings are evenly illuminated.

[0033] Specifically, a storage slot 303 is provided inside the reflective compensation frame 3, and an upper folding plate 301 and a lower folding plate 302 are provided inside the storage slot 303, wherein the upper folding plate 301 is rotatably connected to the lower folding plate 302, and the upper folding plate 301 and the lower folding plate 302 are rotatably connected to the reflective compensation frame 3 respectively, and the reflective compensation frames 3 at both ends can reflect light, and the emitted light can be irradiated between the upper and lower stacked blades;

[0034] The illumination compensation algorithm is as follows:

[0035] I(x,y)=R(x,y)*L(x,y)

[0036] Wherein, I represents reflected light, i.e., light received by the photosensitive component 503, L represents incident light, and R represents the reflective property of an object, which is determined by factors such as the material, shape, and posture of the object and has nothing to do with illumination;

[0037] First, the original image is decomposed into an incident component (corresponding to the low-frequency part of the image) and a reflected component (corresponding to the high-frequency part of the image) in the logarithmic domain. Then, the incident component is predicted by Gaussian smoothing the original image. Then, the incident component is subtracted from the original image to obtain the reflected component. Finally, the antilogarithm of the resulting image is taken to obtain the enhanced image.

[0038] Input image S(x,y)

[0039] ↓

[0040] log transform

[0041] ↓S′(x,y)=logR+logL

[0042] High-pass filtering to obtain the reflection component

[0043] ↓logR(x,y)

[0044] Inverse log transform

[0045] ↓Lighting invariant R

[0046] For image S, assuming that the total number of pixels is n, and the number of pixels with grayscale kr is nk, the grayscale histogram corresponds to the probability density function, and the probability distribution function is the cumulative sum of the histogram, which can be expressed mathematically as follows:

[0047] Probability density

[0048] Probability distribution function:

[0049] The enhancement process of the image space domain point is completed by the enhancement function t = EH (s), t, s are the grayscale values ​​of the pixel point (x, y) on the target image and the original image respectively; the cumulative distribution function can complete the uniform distribution conversion from s to t, and the conversion equation of histogram equalization is as follows:

[0050]

[0051] A standard image Io is defined in advance. The standard image is obtained under standard lighting conditions. For a leaf image I obtained under arbitrary lighting conditions, it is corrected to the same lighting condition as the standard image Io through Gamma transformation, as shown in the formula:

[0052] I x ' y =G(I xy ,γ * )

[0053] Among them, γ * is the Gamma coefficient, which can be obtained by minimizing the difference between the transformed image and the standard image. Its expression is as follows:

[0054]

[0055] The grayscale equalization effect of histogram equalization can weaken the halo effect caused by filtering; the logarithmic transformation converts the division operation into a subtraction operation, which suppresses the noise of the image to a certain extent; the low-frequency component of the image, that is, the incident component related to the illumination, is filtered out by the Gaussian filter, thereby eliminating the image difference caused by illumination changes.

[0056] Specifically, an electric-controlled horizontal rail 1031 is provided on the outer surface of the back panel 103 of the box body, and electric-controlled sliders 1032 are provided at both ends of the electric-controlled horizontal rail 1031. The connection between the upper folding plate 301 and the lower folding plate 302 is connected to the electric-controlled slider 1032. The sliding of the electric-controlled slider 1032 can drive the upper folding plate 301 and the lower folding plate 302 to adjust the angle, thereby realizing different light source reflection operations.

[0057] Working principle: put the vegetable seedlings into the bracket 5012 on the surface of the planting plate frame 501, and use the limiting clamp 502 on the inner side of the bracket 5012 to limit and fix the rhizome of the seedling, and the root of the seedling is located in the hydroponic tank 504. Close the glass flip cover 101, turn on the lighting group 4, and illuminate the seedlings through the lighting group 4 to help the seedlings to photosynthesize. During the lighting process, the photosensitive component 503 on the surface of the planting plate frame 501 can collect light intensity and light information. After integrating the collected data, the angles of the reflective folding plates at both ends can be adjusted, and the light can be reflected between the vegetable leaves through the reflective plates.
