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 has been a boom in protein sources such as meat substitutes due to climate change and environmental issues, floating aquatic plants, preferably duckweed, have been attracting attention as a high-grade food ingredient because they attract significantly less public backlash compared to edible insects, are suitable for vegans, and are a source of high-protein plant-based protein without allergens.

[0003] As more and more Korean and foreign companies are using floating aquatic plants as raw materials for high-protein foods and cosmetics, industrial-scale investment in floating aquatic plants is increasing.

[0004] Emerging aquatic plants grow very quickly, doubling in size every 48 hours. Unlike leafy vegetables or fruits, however, they are harvested whole rather than just a portion of their body tissue, meaning that the overall yield can be greatly varied by adjusting the harvest cycle.

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

[0006] However, this method of harvesting floating aquatic plants has problems not only because it is difficult to do manually and is a labor-intensive production process, but also because it requires people to directly enter the water to work, making it extremely dangerous.

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

[0045] FIG. 1 is a configuration diagram of a floating aquatic plant cultivation device using image recognition according to one 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 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 amount discharge pipe 115 .

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

[0050] The nutrient solution supply pipe 112 is connected at one side to the nutrient solution supply unit 140 and at the other side 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 is formed to protrude from a part of the lower part of the cultivation bed 111 and discharges the nutrient solution of the cultivation bed 111 to the nutrient solution supplying part 140, thereby regulating the water level of the nutrient solution contained in the cultivation bed 111, for example, preventing the floating aquatic plants or the nutrient solution contained in the cultivation bed 111 from overflowing outside the cultivation bed 111. Here, the water level regulating pipe 113 is lower than the height of the nutrient solution supplying pipe 112, the discharge pipe 114, and the large volume discharge pipe 115, and the water level regulating pipe 113 may be formed with a device for preventing the floating aquatic plants from being discharged, such as a filter net.

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

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

[0054] The camera unit 120 is installed at 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 multiple cultivation units 110.

[0055] The control unit 130 detects the emerging aquatic plants from the captured image using image recognition based on the image of the cultivation unit 110 captured by the camera unit 120, and calculates the area of ​​the emerging aquatic plants. Here, since the control unit 130 detects objects and calculates the area using image recognition is a well-known technique, 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] In addition, the control unit 130 analyzes a doubling time of the emerging plants, which is when there is no more space for the emerging plants to float in the cultivation bed 111 and the growth rate of the emerging plants converges to 0, and the area of ​​the emerging plants stops changing, based on the calculated area of ​​the emerging 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 plants calculated by the control unit 130, and can analyze the growth rate of the emerging plants based on the change in the area of ​​the emerging 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 emerged aquatic plants based on the analyzed doubling time using the following Equation 1, and analyzes the harvest volume of the emerged aquatic plants per harvest using the following Equation 2. Here, the control unit 130 learns the harvest volume of the emerged aquatic plants per harvest cycle according to the doubling time of the emerged aquatic plants, and can analyze the harvest cycle and the harvest volume of the emerged 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 the emerging aquatic plants harvested at one time.)

[0061]

number

[0062] (Here, S is the amount of emerging aquatic plants harvested at one time, 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 without a camera unit 120 among the multiple cultivation units 110, 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 without the camera unit 120 by an interpolation method using the harvest cycle and the harvest volume per harvest of the floating aquatic plants housed in the nearby cultivation unit 110 with the camera unit 120. This is to reduce costs since the cost of installing the camera unit 120 in the same location as the cultivation unit 110 increases significantly when there are many cultivation units 110 cultivating floating aquatic plants.

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

[0065] In detail, the control unit 130 controls the supply of nutrient solution from the nutrient solution supply unit 140 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 according to the analyzed harvest cycle of the emerging aquatic plants. 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 located on the surface of the nutrient solution in the cultivation bed 111 flow through the discharge pipe 114 and move to the harvesting unit 150 connected to the discharge pipe 114, where the emerging aquatic plants 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 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 nutrient solution supply unit 140 to control the supply of nutrient solution supplied to the cultivation bed 111 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 required for cultivating the emerging aquatic plants, such as temperature, lighting, wind, etc., and control the temperature, lighting, etc., to suit the cultivation of the emerging aquatic plants, and may analyze the nutrient solution concentration of at least one of the cultivation bed 111 and the nutrient solution supply unit 140, and control the supply of nutrient solution of a concentration suitable for cultivating the emerging aquatic plants to the cultivation bed 111. Here, since the control unit 130 controls the temperature, lighting, nutrient solution concentration, etc., it is a well-known technique, and 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] One side of the nutrient solution supplying unit 140 is connected to the nutrient solution supplying pipe 112 and supplies the nutrient solution to the cultivation bed 111 through the nutrient solution supplying pipe 112 under the control of the control unit 130 .

[0070] In addition, the other side of the nutrient solution supplying unit 140 is connected to the water level regulating pipe 113 and the harvesting unit 150, and the nutrient solution contained in the cultivation bed 111 discharged through the water level regulating pipe 113 and the nutrient solution discharged to the harvesting unit 150 are moved and stored. Here, the nutrient solution supplying 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 on one side to the discharge pipe 114 and the mass discharge pipe 115. 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, separates the floating aquatic plants and the nutrient solution through the filter net, and discharges and moves the nutrient solution that has moved to the lower part through the filter net to the nutrient solution supplying unit 140 connected to the other side, and allows the user to harvest the floating aquatic plants that have been classified to the upper part through the filter net.

[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 amount of harvested in one 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 adjustment pipe 113, a discharge pipe 114, a large amount of 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 adjustment pipe 113, the discharge pipe 114, and the large amount of discharge pipe 115 are the same as those in FIG. 1 and FIG. 2, so 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 harvest cycle and the harvest amount per harvest of the analyzed floating 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 emerged aquatic plants based on the analyzed doubling time of the emerged aquatic plants.

[0081] In step S440, the control unit 130 determines whether it is the harvest cycle of the analyzed emerging aquatic plants, and if it is the harvest 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 supplying unit 140 or the harvest pump 310 to harvest the floating aquatic plants in a single harvesting 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 at or above the height of the discharge pipe 114 and below the mass discharge pipe 115, so that the floating aquatic plants located 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] Although the embodiments of the present invention have been described above, they are merely illustrative, and a person skilled in the art to which the present invention pertains would understand 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]
