Description

[Technical Field]

[0001] The present invention relates to a floating aquatic plant cultivation device and method that utilizes image recognition. [Background technology]

[0002] While there is a boom in protein sources such as meat substitutes due to climate change and environmental issues, floating aquatic plants, especially duckweed, are attracting attention as a luxury food ingredient because they attract significantly less public backlash than edible insects, are suitable for vegans, and are a source of high-quality plant protein without allergens.

[0003] As more and more companies in Korea and abroad are using floating aquatic plants as ingredients in high-protein foods and cosmetics, industrial-scale investment in floating aquatic plants is on the rise.

[0004] Floating aquatic plants grow very quickly, doubling in size every 48 hours. However, unlike leafy vegetables or fruits, they are harvested whole rather than just a portion of their body tissue, so adjusting the harvest cycle can greatly affect the overall yield.

[0005] Traditionally, floating aquatic plants have mainly grown naturally along the estuaries of rivers, ponds, and reservoirs, and have been collected by hand by people wearing full-length boots and entering the water using a landing net.

[0006] However, this method of harvesting floating aquatic plants is problematic not only because it is a labor-intensive, manual process, but also because it requires people to enter the water to work, making it extremely dangerous.

[0007] Furthermore, floating aquatic plants in rivers are particularly contaminated with heavy metals, which poses problems in terms of the food and pharmaceutical stability of the raw materials and the safety of the plants when harvested. [Prior art documents] [Patent documents]

[0045] FIG. 1 is a diagram showing the configuration of a floating aquatic plant cultivation device that utilizes image recognition according to an embodiment of the present invention.

[0046] FIG. 2 is a configuration diagram of a cultivation unit according to an embodiment of the present invention.

[0047] Referring to Figures 1 and 2, the floating aquatic plant cultivation device 100 utilizing image recognition includes a cultivation unit 110, a camera unit 120, a control unit 130, a nutrient solution supply unit 140, a harvesting unit 150, and a storage unit 160. The cultivation section 110 receives the nutrient solution from the nutrient solution supply section 140 and accommodates the supplied nutrient solution and the floating aquatic plants.

[0048] The cultivation section 110 includes a cultivation bed 111, a nutrient solution supply pipe 112, a water level adjustment pipe 113, a discharge pipe 114, and a large-volume discharge pipe 115.

[0049] The cultivation bed 111 accommodates the nutrient solution supplied from the nutrient solution supply unit 140 via the nutrient solution supply pipe 112 and the floating aquatic plants.

[0050] The nutrient solution supply pipe 112 is connected at one end to the nutrient solution supply unit 140 and at the other end to the cultivation bed 111, so that the nutrient solution supplied from the nutrient solution supply unit 140 moves and is supplied to the cultivation bed 111.

[0051] The water level regulating pipe 113 protrudes from a part of the lower part of the cultivation bed 111 and discharges the nutrient solution in the cultivation bed 111 to the nutrient solution supply unit 140, thereby regulating the water level of the nutrient solution contained in the cultivation bed 111, for example, preventing the floating aquatic plants contained in the cultivation bed 111 or the nutrient solution from overflowing outside the cultivation bed 111. Here, the water level regulating pipe 113 is lower than the height of the nutrient solution supply pipe 112, the discharge pipe 114, and the large-volume discharge pipe 115, and the water level regulating pipe 113 may be provided with a device such as a filter net to prevent the floating aquatic plants from being discharged.

[0052] The discharge pipe 114 is formed at a lower part of the cultivation bed 111 at a position spaced apart from the water level control pipe 113 and protrudes higher than the water level control pipe 113 to discharge the floating aquatic plants to the connected harvesting unit 150 .

[0053] The large-volume discharge pipe 115 is connected to the cultivation bed 111 on one side and to the harvesting unit 150 on the other side at a part higher than the discharge pipe 114, so that the floating aquatic plants can be harvested in large quantities.

[0054] The camera unit 120 is installed in a location where it can capture an image of the cultivation unit 110, and captures an image of the cultivation unit 110. Here, the camera unit 120 may be installed in only some of the plurality of cultivation units 110.

[0055] The control unit 130 detects emerging aquatic plants from the captured image of the cultivation unit 110 using image recognition and calculates the area of ​​the emerging aquatic plants based on the captured image of the cultivation unit 110 captured by the camera unit 120. Here, since the control unit 130 detects objects and calculates their area using image recognition is a well-known technology, detailed description will be omitted, but the image recognition used by the control unit 130 may be U-Net or various deep learning methods capable of semantic segmentation.

[0056] Furthermore, based on the calculated area of ​​the emerging aquatic plants, the control unit 130 analyzes the doubling time of the emerging aquatic plants, which is the time when there is no more space for the emerging aquatic plants to float in the cultivation bed 111 and the growth rate of the emerging aquatic plants converges to 0, resulting in no change in the area of ​​the emerging aquatic plants. Here, the control unit 130 learns from at least one of the image captured by the camera 120 stored in the storage unit 160 and the area of ​​the emerging aquatic plants calculated by the control unit 130, and can analyze the growth rate of the emerging aquatic plants based on the change in the area of ​​the emerging aquatic plants over time, and can also analyze the doubling time based on the analyzed growth rate.

[0057] The control unit 130 analyzes the harvesting cycle and the harvest amount of the emerging aquatic plants per harvest based on the analyzed doubling time.

[0058] In detail, the control unit 130 analyzes the harvest cycle of the emerging aquatic plants based on the analyzed doubling time using the following Equation 1, and analyzes the harvest volume of the emerging aquatic plants per harvest using the following Equation 2. Here, the control unit 130 learns the harvest volume of the emerging aquatic plants per harvest cycle according to the doubling time of the emerging aquatic plants, and can analyze the harvest cycle and the harvest volume of the emerging aquatic plants per harvest.

[0059]

number

[0060] (Here, △t optomal is the harvest cycle of the emerging aquatic plants, D is the doubling time of the emerging aquatic plants, and S is the amount of emerging aquatic plants harvested in one time.)

[0061]

number

[0062] (Here, S is the amount of emerging aquatic plants harvested in one go, D is the doubling time of the emerging aquatic plants, and t is the harvesting cycle of the emerging aquatic plants.)

[0063] If there is a cultivation unit 110 among the plurality of cultivation units 110 that does not have a camera unit 120, the control unit 130 analyzes the harvest cycle and the harvest volume per harvest of the floating aquatic plants housed in the cultivation unit 110 that does not have a camera unit 120 by interpolation using the harvest cycle and the harvest volume per harvest of the floating aquatic plants housed in the nearby cultivation unit 110 that has a camera unit 120. This is to reduce costs because if there are many cultivation units 110 that cultivate floating aquatic plants, the cost would increase significantly if the camera unit 120 were installed in the same place as the cultivation unit 110.

[0064] In addition, the control unit 130 controls the supply of nutrient solution by the nutrient solution supply unit 140, and moves the emerging aquatic plants contained in the cultivation bed 111 to the harvesting unit 150 based on the analyzed harvest cycle of the emerging aquatic plants and the harvest amount per harvest.

[0065] Specifically, the control unit 130 controls the supply of nutrient solution from the nutrient solution supply unit 140 according to the analyzed harvest cycle of the emerging aquatic plants so that the water level of the nutrient solution contained in the cultivation bed 111 is maintained above the height of the discharge pipe 114 and below the mass discharge pipe 115. In this case, when the water level of the nutrient solution contained in the cultivation bed 111 is above the height of the discharge pipe 114, the emerging aquatic plants present on the surface of the nutrient solution in the cultivation bed 111 flow through the discharge pipe 114 and move to the harvester 150 connected to the discharge pipe 114, where they can be harvested.

[0066] Next, the control unit 130 analyzes the image captured by the camera unit 120, and if the amount of change in the number of floating aquatic plants in the cultivation bed 111 due to the floating aquatic plants discharged through the discharge pipe 114 corresponds to the analyzed harvest yield for one time, the control unit 130 controls the supply of nutrient solution to be supplied to the cultivation bed 111 by controlling the nutrient solution supply unit 140 so that the water level of the nutrient solution contained in the cultivation bed 111 is below the height of the discharge pipe 114.

[0067] The control unit 130 may analyze environmental information necessary for cultivating the emerging aquatic plants, such as temperature, lighting, and wind, and control the temperature, lighting, etc., to suit the cultivation of the emerging aquatic plants, and may analyze the concentration of the nutrient solution in at least one of the cultivation bed 111 and the nutrient solution supply unit 140, and control the supply of the nutrient solution of a concentration suitable for the cultivation of the emerging aquatic plants to the cultivation bed 111. Here, the control of the temperature, lighting, nutrient solution concentration, etc., by the control unit 130 is well known technology, and therefore a detailed description thereof will be omitted.

[0068] In addition, the control unit 130 learns based on at least one of the images captured by the camera unit 120 periodically stored in the storage unit 160, the doubling time of the emerging aquatic plants analyzed by the control unit 130, the harvesting cycle of the emerging aquatic plants, and the harvest amount per harvest.

[0069] The nutrient solution supply unit 140 is connected to the nutrient solution supply pipe 112 on one side, and supplies the nutrient solution to the cultivation bed 111 through the nutrient solution supply pipe 112 under the control of the control unit 130 .

[0070] The other side of the nutrient solution supply unit 140 is connected to the water level adjusting pipe 113 and the harvesting unit 150, and the nutrient solution contained in the cultivation bed 111 and discharged through the water level adjusting pipe 113 and the nutrient solution discharged to the harvesting unit 150 are moved and stored. Here, the nutrient solution supply unit 140 is connected to a nutrient solution raw material tank (not shown) and a water supply tank (not shown), and can supply nutrient solution raw material and water under the control of the control unit 130.

[0071] The harvesting unit 150 is provided with a filter net (not shown), and is connected to the discharge pipe 114 and the mass discharge pipe 115 on one side. The harvesting unit 150 receives the floating aquatic plants and nutrient solution discharged to either the discharge pipe 114 or the mass discharge pipe 115, and separates the floating aquatic plants from the nutrient solution through the filter net. The nutrient solution that moves to the bottom through the filter net is discharged and moved to the nutrient solution supplying unit 140 connected to the other side, and the floating aquatic plants that are separated to the top through the filter net can be harvested by the user.

[0072] The storage unit 160 stores the images captured by the camera unit 120, the doubling time of the emerging aquatic plants analyzed by the control unit 130, the harvesting cycle of the emerging aquatic plants, and the harvest amount per harvest.

[0073] FIG. 3 is a configuration diagram of a cultivation unit according to another embodiment of the present invention.

[0074] 3, the cultivation unit 110 includes a cultivation bed 111, a nutrient solution supply pipe 112, a water level adjusting pipe 113, a discharge pipe 114, a mass discharge pipe 115, and a harvest pump 310. Here, the cultivation unit 110, the cultivation bed 111, the nutrient solution supply pipe 112, the water level adjusting pipe 113, the discharge pipe 114, and the mass discharge pipe 115 are the same as those in FIGS. 1 and 2, and therefore detailed description thereof will be omitted.

[0075] The harvest pump 310 is installed near the discharge pipe 114 inside the cultivation bed 111, and under the control of the control unit 130, sucks up the nutrient solution and floating aquatic plants on the surface of the cultivation bed 111 and discharges the nutrient solution and floating aquatic plants into the discharge pipe 114.

[0076] Here, the control unit 130 may control the operation of the harvest pump 310 in accordance with the analyzed harvest cycle and the harvest amount per harvest of the emerging aquatic plants.

[0077] FIG. 4 is a flowchart of a method for cultivating floating aquatic plants using image recognition according to another embodiment of the present invention.

[0078] Referring to FIG. 4, in step S410, the camera unit 120 captures an image of the cultivation unit 110 in which the floating aquatic plants are housed.

[0079] In step S420, the control unit 130 uses image recognition to calculate the area of ​​the emerging aquatic plants based on the image captured by the camera unit 120, and analyzes the doubling time of the emerging aquatic plants based on the calculated area of ​​the emerging aquatic plants.

[0080] In step S430, the control unit 130 analyzes the harvesting cycle and the harvest amount per harvest of the emerging aquatic plants based on the analyzed doubling time of the emerging aquatic plants.

[0081] In step S440, the control unit 130 determines whether it is the harvesting cycle of the analyzed emerging aquatic plants, and if it is the harvesting cycle of the emerging aquatic plants, the process proceeds to step S450, and if not, the process returns to step S410.

[0082] In step S450, the control unit 130 controls the nutrient solution supply unit 140 or the harvest pump 310 to harvest the floating aquatic plants in a single harvest amount.

[0083] In detail, the control unit 130 analyzes the image captured by the camera unit 120 and controls the nutrient solution supply unit 140 to supply nutrient solution to the cultivation bed 111 until the amount of change in floating hydrogen in the cultivation bed 111 due to the floating aquatic plants discharged through the discharge pipe 114 corresponds to the analyzed harvest amount for one time, thereby maintaining the water level of the nutrient solution contained in the cultivation bed 111 above the height of the discharge pipe 114 and below the mass discharge pipe 115.The floating aquatic plants on the surface of the nutrient solution flow through the discharge pipe 114 and move to the harvesting unit 150 connected to the discharge pipe 114 so that the floating aquatic plants can be harvested, or controls the harvesting pump 310 to suck up the nutrient solution and the floating aquatic plants on the surface of the cultivation bed 111 and then discharge the nutrient solution and the floating aquatic plants into the discharge pipe 114 so that the floating aquatic plants can be harvested.

[0084] While the embodiments of the present invention have been described above, they are merely illustrative, and those skilled in the art will recognize that various modifications and equivalent embodiments are possible. Therefore, the true technical scope of the present invention should be determined by the following claims. [Explanation of symbols]
