Preferably, the present invention can be performed in the following manner when determining the positions and the number of the several light sources 120 participating in illumination on the illumination panel 110 according to the illuminated pattern and the area of the plant. Preferably, in the case of a plant, the control unit of the light source arrangement system 100 may adjust the corresponding light source 120 in such a way that the illumination surface of the illumination plate 110 is larger than the projection area of the illuminated surface of the plant currently illuminated, and the image acquisition device disposed on the backlight surface of the plant acquires a visual image including both light transmitted through the plant and light not transmitted through the plant; the control unit recognizes and acquires the peripheral outline of the current plant based on the difference of brightness values of all the blocks in the visual image; the control unit adjusts the turning on or off of the respective light sources 120 on the illumination plate 110 based on the identified peripheral profile, the adjustment rules being: when there is no projection of the plant or projection of the plant outline on the position corresponding to the light source 120, the light source 120 is turned off, otherwise, turned on. According to the scheme, modularization and unitization illumination by the light source 120 are realized, the difficulty of determining the plant boundary by using a visual recognition mode is greatly reduced based on the principle of light transmission brightness reduction, and the conventional visual recognition mode aims at a plurality of plants with space depth of field and overlapping instead of uniformly distributed on a plane, so that the accurate outline of the plant is difficult to obtain, the recognition algorithm is complex, more calculation resources are consumed, and the construction and maintenance costs are high. The scheme provides an additional purpose for the light source 120 for plant illumination, and based on the transmission of the light source 120, the outline position of the plant can be simply, conveniently and accurately obtained, and the outline can be just used for the switch regulation and control of the single light source 120 in a feedback manner. Additionally, under the requirement of acquiring the growth condition of the plant, the shape of the light source 120 started on the illumination plate 110 is simply acquired, so that the growth profile of the current plant can be approximately acquired, and a person can intuitively see that the leaves at a certain position of the plant are more prominent and the leaves at a certain position are more rare. In other words, the present solution provides a luminous shaped block that can twinkle in projection against the plant physical growth, and also provides an intuitive characterization of the plant outline, while providing the precise illumination required by the plant. In another embodiment, the control unit only recognizes the rough luminance value of each block, for example, the luminance value that is not blocked is generally constant at a value, the blocked luminance value decreases at least to a smaller value, and then by roughly dividing the luminance value, the control unit can more quickly acquire the position where the blocked light is emitted, and then can quickly control part of the light sources 120 to be turned off, that is, the control unit determines the outline of the plant at the accuracy of the single light source 120, in which case the single light source 120 is similar to a pixel point in the video information. The embodiment can further reduce processing delay, reduce data calculation amount, is remarkably beneficial to high-precision tracking of the plant growth process, and is more beneficial to cultivating high-value plants.

Preferably, the control unit may process the image to divide the image into a plant part and a blank part; and determining whether the light source 120 corresponding to the sub-area participates in illumination by determining whether the coverage ratio of the plant part in the sub-area exceeds 25%.
Preferably, the composition, preferably, the control unit can extract the image of the small xanthum plants from the image acquired by the image acquisition device, comparing the image of the small xantham plant with the data pre-stored in the database, thereby determining the growth state of the small xantham plants and further determining the current optimal illumination wavelength of the small xantham plants to adjust the light emission wavelength of the light source 120.
Preferably, when the herba Xanthii plant is in the reproductive growth stage, the control unit generates a control instruction, so that the light source 120 irradiates the herba Xanthii plant with the fourth light bulb to promote the increase of chlorophyll content of the herba Xanthii plant, and further promote the increase of dry weight of the herba Xanthii plant.
Preferably, when the herb is in vegetative growth phase and it is desired to promote differentiation and shaping of the root, the control unit generates control instructions such that the light source 120 irradiates the herb with the third beads.

Preferably, the elevating mechanism may adjust the height between the illumination plate 110 and the cultivating plate 130 when the light source 120 switches the light emitting wavelength, thereby adjusting the light intensity and temperature of the light source 120 projected onto the plant leaves, preventing the plant leaves from being burned.
Example 2
This embodiment is a further improvement of embodiment 1, and the repeated contents are not repeated.
Preferably, the light source arrangement method provided in this embodiment further includes: the abnormal growth plants are highlighted to distinguish them from the normal growth plants.
Preferably, the plant with abnormal growth is subjected to highlighting illumination, which specifically comprises: acquiring an image of the plant on the cultivating plate 130, and identifying the image to determine the type of the plant, wherein the type of the plant at least comprises a growth abnormality type and a growth normal type; after identifying the abnormal growth plant and the normal growth plant, the light source 120 irradiating the normal growth plant is turned off, and the abnormal growth plant is highlighted from the cultivating plate 130 so that the manager can determine the position of the abnormal growth plant to be treated.
Preferably, after the manager processes the abnormal growth plant, the light source 120 irradiating the abnormal growth plant is turned off, so that the manager can determine whether the abnormal growth plant is processed by observing the number of the light sources 120 in the on state.
Preferably, the present invention concentrates the abnormally grown plants through the illumination panel 110, and highlights the abnormally grown plants from the normal plants.
Preferably, when plants are cultivated, a plurality of plants are planted on the single plant growing area 140, and the control unit may acquire an image of each plant using the image acquisition device, thereby adjusting the illumination environment of each plant. Preferably, after the control unit acquires an image of a single plant through the image acquisition device, the position and the number of the light sources 120 illuminating the plant can be determined according to the position of the plant on the planting area 140, and the control unit can also determine the growth state of the single plant according to the image of the single plant, so as to determine the light emitting wavelength of the light sources 120 illuminating the plant.
Plants grown in plant factories often need to be screened after harvest to screen off reject. The invention can regulate the plant growth by changing the illumination environment of the plant to regulate the expression of the plant photosensitive genes, but the growth of the plant is influenced by factors such as temperature, humidity, seed quality and the like besides the illumination environment. Thus, when the light source arrangement system 100 cultures several plants located on the same cultivating plate 130, there may be a difference in growth rate of the different plants.
Preferably, the control unit may determine the growth rate of the plant by comparing images of the same plant before and after the cultivation for a preset period of time during the cultivation of the plant. Preferably, during the cultivation of the plant, the control unit may also compare the image of the plant with images pre-stored in a database, so as to determine the growth stage in which the plant is located.
Preferably, the control unit can determine the growth rate of the individual plants and the growth stage of the individual plants by processing the images acquired by the image acquisition device. Preferably, the control unit may aggregate the growth rate of each plant on the growth plate 130 and the growth stage at which it is positioned, thereby determining a standard growth rate and a standard growth stage for plants grown on the growth plate 130.
Preferably, the control unit may determine the growth rate of the individual plants based on the images acquired by the image acquisition device. Preferably, when the growth rate of the plants exceeds the standard growth rate, the control unit may inhibit the growth of the plants that grow too fast by adjusting the emission wavelength of the light source 120 so that the plants on the cultivating plate 130 may enter the harvest stage in the same batch as much as possible. For example, when a certain plant of the Siberian cocklebur cultivated on the cultivating plate 130 grows too fast, the control unit may adjust the light source 120 illuminating the plant of the Siberian cocklebur such that the light source 120 irradiates the plant of the Siberian cocklebur with the second light beads or such that the light source 120 no longer provides light to the plant of the Siberian cocklebur which grows too fast, thereby inhibiting its growth.
Preferably, the light source arrangement system 100 provided by the invention can adjust the illumination environment of each plant on the same cultivation plate 130 to regulate and control the plant growth, so that the growth and development degree of each plant on the same cultivation plate 130 tend to be consistent, and the screening amount of the harvested plants is reduced.
Preferably, the plants grown on the growth plate 130 have a coverage that gradually increases as the growth progresses, resulting in staggered overlap of leaves of adjacent plants. Preferably, the control unit may preferentially adjust the light source 120 irradiating the plant without corresponding to the overlapping portion of other plants when adjusting the light emitting wavelength of the light source 120 to inhibit the growth of the plant, so as to avoid inhibiting other plants with normal growth rate.
Preferably, in the process of cultivating the plant, the control unit may acquire an image of the plant through the image acquisition device, and the control unit may identify the image of the plant through the recognition model subjected to the deep learning, thereby determining the type of the plant. The types of plants include at least a growth abnormality type and a growth normal type. Preferably, the type of growth abnormality may include: pre-developed plants, as well as dysplastic and/or pest-bearing plants.
Preferably, the control unit may adjust the emission wavelength of the light source 120 to inhibit development of the pre-developed plant after it is identified. Preferably, the control unit may also send a signal to a management end used by plant factory manager when the pre-developed plant is identified, to prompt the manager to pick the pre-developed plant in advance. Preferably, the control unit is signally connected to the management end used by plant factory management personnel by wired or wireless means. Preferably, the management end used by the plant factory manager can be an intelligent terminal such as an intelligent mobile phone, a tablet personal computer and the like worn by the manager.
Preferably, the control unit may send a signal to a management end used by plant factory manager when a maldeveloped plant and/or a plant with a pest is identified to prompt the manager to treat the maldeveloped plant and/or the plant with the pest.
Preferably, when treating pre-developed plants, ill-developed plants, and/or plants that are pest-causing, the manager may utilize the light source arrangement system 100 to locate and display the plants that need to be treated. Preferably, the light source arrangement system 100 can distinguish between plants to be treated and normal plants when the manager treats pre-developed plants, ill-developed plants, and/or plants that are pest-damaged.
Preferably, the control unit may generate a prompt to be sent to the management end used by plant factory management after identification of pre-developed plants, dysplastic plants and/or pest-causing plants. Preferably, when the manager processes the plant to be processed according to the prompt, the manager can send an instruction to the control unit through the management end, so that the control unit adjusts the light emitting mode of the light source 120 on the lighting panel 110 to distinguish the plant to be processed from a normal plant.
Preferably, the instruction sent by the manager to the control unit through the management end may include: picking a first instruction of a plant which grows in advance, a second instruction of a plant which grows poorly, and a third instruction of controlling a plant which is a plant disease and insect pest.
Preferably, after the manager sends the first instruction to the control unit through the management end, the control unit sends the control instruction to the light source 120 on the lighting board 110, so that the light source 120 irradiating the area where the plant growing ahead is located emits light, and the other light sources 120 are extinguished, so that the plant growing ahead is highlighted from a plurality of plants cultivated on the cultivating board 130. Although the pre-developed plants differ significantly in individual size or stem and leaf morphology from the normal developed plants, when the pre-developed plants are intermixed in the normal developed plants, it is difficult for the human eye to distinguish the pre-developed plants from the normal developed plants if there is no obvious color distinction between the pre-developed plants and the normal developed plants. Preferably, the control unit adjusts the light source 120 on the illumination panel 110 to illuminate only the pre-developed plants, thereby highlighting the pre-developed plants from the normal developed plants, facilitating the manager to determine the picking targets. Preferably, when the manager picks the pre-developed plant, the control unit may determine that the pre-developed plant has been picked through the image acquired by the image acquisition device, and generate the control instruction to turn off the light source 120 corresponding to the pre-developed plant according thereto, so that the manager may determine whether the picking is completed by observing the number of the light sources 120 in a light emitting state. Preferably, the control unit extinguishes the light source 120 corresponding to the plant of advanced development after the manager picks the plant of advanced development, so that the manager can be prevented from missing picking or repeatedly picking, and the efficiency of single picking is improved.
Preferably, after the manager sends the second instruction to the control unit through the management end, the control unit sends the control instruction to the light source 120 on the lighting board 110, so that the light source 120 irradiating the area where the dysplastic plant is located emits light, and the other light sources 120 are extinguished, so as to indicate the area where the dysplastic plant is located to the manager. The dysplastic plants are short in individuals compared with normal plants, and are easily blocked by normal plants, so that the dysplastic plants are difficult to observe by naked eyes for management staff. Preferably, when the manager removes the ill-developed plant, the control unit may determine that the ill-developed plant does not exist in the area irradiated by the light source 120 through the image acquired by the image acquisition device, thereby generating the control instruction to turn off the light source 120 corresponding to the area. Preferably, the manager can determine whether to completely remove the dysplastic plants by observing the number of light sources 120 in the lighted state.
Preferably, after the manager sends a third instruction to the control unit through the management end, the control unit sends a control instruction to the light source 120 on the lighting board 110, so that the light source 120 irradiating the plant of the plant diseases and insect pests emits light, and the other light sources 120 are extinguished, thereby indicating the position of the plant diseases and insect pests to the manager. Preferably, the manager may dose or remove the pest-causing plants according to the direction of the light source arrangement system 100. Preferably, the light source arrangement system 100 may prompt a manager to treat a plant in the event of a pest, thereby preventing pest spread.
