Description

Technical Field

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

[0002] As protein sources such as plant-based meat are being actively developed due to climate change, environmental issues, etc., floating algae are attracting attention as an advanced food ingredient because they are significantly less offensive to eating than insects, are suitable for vegetarians, and are a plant-based high-protein source without allergens.

[0003] As a result, there are more and more cases of domestic and foreign companies using floating water plants as high-protein foods or cosmetic ingredients, and the investment in the floating water plants industry is also increasing.

[0004] Floating aquatic plants grow very fast, doubling in size every 48 hours. However, unlike leafy vegetables or fruiting vegetables, individuals are harvested as a whole rather than as part of their body tissue. Therefore, the total harvest amount can vary greatly as the harvest cycle is adjusted.

[0005] In the past, floating aquatic plants mainly grew freely along the river estuaries or in ponds, reservoirs, etc. Therefore, people had to wear chest boots and go into the water directly and use fishing nets to collect them manually.

[0006] However, this method of collecting floating water plants not only has the problem of difficulty in manual work and labor-intensive production process, but also has the problem of being very dangerous because people are required to directly enter the water to work.

[0007] Furthermore, in particular, in the case of floating aquatic plants in rivers, they are seriously contaminated with heavy metals, so there are problems with the stability of the raw materials for food and medicine and the safety of the collection process.

[0008] Prior art document: Korean patent No. 10-0279462 (granted on June 11, 2002) Summary of the invention

[0059] Figure 1 This is a structural diagram of a floating aquatic plant cultivation device using image recognition according to an embodiment of the present invention.

[0060] Figure 2 It is a structural diagram of a cultivation section according to an embodiment of the present invention.

[0061] Reference Figure 1 as well as Figure 2The floating aquatic plant cultivation device 100 using 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 .

[0062] The cultivation section 110 receives the nutrient solution from the nutrient solution supply section 140 and houses the received nutrient solution and floating water plants.

[0063] 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-capacity discharge pipe 115 .

[0064] The cultivation bed 111 receives the nutrient solution and floating water plants supplied from the nutrient solution supply unit 140 through the nutrient solution supply pipe 112 .

[0065] One side of the nutrient solution supply pipe 112 is connected to the nutrient solution supply unit 140 , and the other side is connected to the cultivation bed 111 , whereby the nutrient solution supplied from the nutrient solution supply unit 140 moves to the cultivation bed 111 and is supplied.

[0066] The water level regulating pipe 113 is formed by protruding from a part of the lower part of the cultivation bed 111 and regulating the water level of the nutrient solution contained in the cultivation bed 111. For example, the nutrient solution in the cultivation bed 111 is discharged to the nutrient solution supply unit 140 to prevent the floating waterweed contained in the cultivation bed 111 or the nutrient solution from overflowing to the outside of the cultivation bed 111. The water level regulating pipe 113 may be lower than the height of the nutrient solution supply pipe 112, the discharge pipe 114, and the large-capacity discharge pipe 115, and a filter screen or the like for preventing the floating waterweed from being discharged may be formed in the water level regulating pipe 113.

[0067] The discharge pipe 114 is formed to protrude higher than the water level regulating pipe 113 at a position separated from the water level regulating pipe 113 in a part of the lower portion of the cultivation bed 111 , and discharges the floating waterweeds toward the connected harvesting unit 150 .

[0068] The large-capacity discharge pipe 115 is connected to the cultivation bed 111 on one side and to the harvesting part 150 on the other side at a portion higher than the discharge pipe 114, so that a large amount of floating aquatic plants can be harvested.

[0069] The camera unit 120 is disposed at a position where the cultivating unit 110 can be photographed to capture an image of the cultivating unit 110 . The camera unit 120 may be disposed only at a portion of the cultivating units 110 .

[0070] The control unit 130 detects floating waterweeds from the image of the cultivation unit 110 captured by the camera unit 120 and uses image recognition to calculate the area of ​​the floating waterweeds. The technology of detecting an object and calculating the area by the control unit 130 using image recognition is a well-known technology, so detailed description is omitted. The image recognition used by the control unit 130 can be various deep learning methods such as U-Net or semantic segmentation.

[0071] In addition, the control unit 130 analyzes the doubling time of floating waterweeds when there is no space for floating waterweeds to float further in the cultivation bed 111 and the growth rate of floating waterweeds converges to 0, and there is no change in the area of ​​floating waterweeds, based on the calculated area of ​​floating waterweeds. The control unit 130 can learn from at least one of the images captured by the camera unit 120 stored in the storage unit 160 and the area of ​​floating waterweeds calculated by the control unit 130, and analyze the cultivation speed of floating waterweeds based on the change in the area of ​​floating waterweeds that changes over time, and can also analyze the doubling time based on the analyzed cultivation speed.

[0072] The control unit 130 analyzes the harvesting cycle and the amount of one harvest of the floating aquatic plants based on the analyzed doubling time.

[0073] Specifically, the control unit 130 analyzes the harvest cycle of floating water plants based on the analyzed doubling time and using the following first mathematical formula, and analyzes the one-time harvest amount of floating water plants using the following second mathematical formula. The control unit 130 uses the one-time harvest amount of floating water plants of each harvest cycle of floating water plants of the doubling time of floating water plants to learn, and analyzes the harvest cycle of floating water plants and the one-time harvest amount.

[0074] [First mathematical formula]

[0075] △t optimal =Dlog2DS

[0076] Among them, △t optomal is the harvesting cycle of floating aquatic plants, D is the doubling time of floating aquatic plants, and S is the amount of floating aquatic plants harvested at one time.

[0077] [Second mathematical formula]

[0078]

[0079] Among them, S is the amount of floating water plants harvested at one time, D is the doubling time of floating water plants, and t is the harvesting cycle of floating water plants.

[0080] When there is a cultivation section 110 without the camera 120 among the plurality of cultivation sections 110, the control section 130 uses the harvesting cycle and the harvesting amount of floating aquatic plants contained in the nearby cultivation section 110 with the camera 120 and analyzes the harvesting cycle and the harvesting amount of floating aquatic plants contained in the cultivation section 110 without the camera 120 by interpolation. This is to save costs, because if there are many cultivation sections 110 for cultivating floating aquatic plants, if the camera 120 is provided in the same manner as the cultivation section 110, the cost will increase.

[0081] In addition, the control unit 130 controls the supply of the nutrient solution of the nutrient solution supply unit 140, and moves the floating aquatic plants stored in the cultivation bed 111 to the harvesting unit 150 according to the analyzed harvesting cycle and one-time harvesting amount of the floating aquatic plants.

[0082] Specifically, the control unit 130 controls the supply of the nutrient solution of 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 large-capacity discharge pipe 115 according to the analyzed harvesting cycle of the floating waterweed. At this time, as the water level of the nutrient solution contained in the cultivation bed 111 is above the height of the discharge pipe 114, the floating waterweed located on the surface of the nutrient solution of the cultivation bed 111 flows through the discharge pipe 114 and moves to the harvesting unit 150 connected to the discharge pipe 114, so that the floating waterweed can be harvested.

[0083] Next, the control unit 130 analyzes the image taken by the camera unit 120. If the change in the floating aquatic plants in the cultivation bed 111 caused by the floating aquatic plants discharged through the discharge pipe 114 corresponds to the analyzed single-time harvest amount, the nutrient solution supply unit 140 is controlled to control the 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.

[0084] The control unit 130 can analyze the environmental information such as temperature, lighting, wind, etc. required for cultivating floating waterweeds, and control the temperature, lighting, etc. to be suitable for the cultivation of floating waterweeds, analyze the concentration of the nutrient solution of at least one of the cultivation bed 111 and the nutrient solution supply unit 140, and control to supply the nutrient solution of the concentration suitable for the cultivation of floating waterweeds to the cultivation bed 111. Among them, the control unit 130 controls the temperature, lighting, and nutrient solution concentration, etc., which is a well-known technology, and therefore a detailed description is omitted.

[0085] In addition, the control unit 130 periodically learns at least one of the images captured by the camera unit 120 and stored in the storage unit 160, the doubling time of floating aquatic plants analyzed by the control unit 130, the harvesting cycle of floating aquatic plants, and the amount of harvesting at one time.

[0086] One side of the nutrient solution supply unit 140 is connected to the nutrient solution supply pipe 112 , and supplies the nutrient solution to the cultivation bed 111 through the nutrient solution supply pipe 112 according to the control of the control unit 130 .

[0087] In addition, the other side of the nutrient solution supply unit 140 is connected to the water level regulating pipe 113 and the harvesting unit 150, so that the nutrient solution discharged through the water level regulating pipe 113 and the nutrient solution contained in the cultivation bed 111 and the nutrient solution discharged to the harvesting unit 150 are moved and stored. 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 receives nutrient solution raw materials and water supply according to the control of the control unit 130.

[0088] The harvesting section 150 is provided with a filter screen (not shown), one side of which is connected to the discharge pipe 114 and the large-capacity discharge pipe 115, receives the floating aquatic plants and nutrient solution discharged into any one of the discharge pipe 114 and the large-capacity discharge pipe 115, and classifies the floating aquatic plants and the nutrient solution through the filter screen. The nutrient solution moving to the lower part through the filter screen is discharged and moved to the nutrient solution supply section 140 connected to the other side, and the floating aquatic plants classified in the upper part through the filter screen are harvested by the user.

[0089] The storage unit 160 stores the images captured by the camera unit 120 , the doubling time of the floating aquatic plants analyzed by the control unit 130 , the harvesting cycle of the floating aquatic plants, and the amount of the floating aquatic plants harvested once.

[0090] Figure 3 It is a structural diagram of a cultivation section according to another embodiment of the present invention.

[0091] Reference Figure 3 The cultivation part 110 includes a cultivation bed 111, a nutrient solution supply pipe 112, a water level regulating pipe 113, a discharge pipe 114, a large-capacity discharge pipe 115, and a harvesting pump 310. The cultivation bed 111, the nutrient solution supply pipe 112, the water level regulating pipe 113, the discharge pipe 114, and the large-capacity discharge pipe 115 are connected to the harvesting pump 310. Figure 1 as well as Figure 2 The same, so the detailed description is omitted.

[0092] The harvesting pump 310 is disposed near the discharge pipe 114 in the cultivation bed 111 , and according to the control of the control unit 130 , it sucks the nutrient solution and floating aquatic plants on the surface of the cultivation bed 111 , and discharges the nutrient solution and floating aquatic plants to the discharge pipe 114 .

[0093] The control unit 130 controls the driving of the harvesting pump 310 in accordance with the analyzed harvesting cycle and the amount of the floating aquatic plants harvested at one time.

[0094] Figure 4 This is a flow chart of a floating aquatic plant cultivation method using image recognition according to another embodiment of the present invention.

[0095] Reference Figure 4 In step S410, the camera unit 120 captures an image of the cultivation unit 110 containing floating aquatic plants.

[0096] In step S420 , the control unit 130 uses image recognition to calculate the area of ​​floating water plants based on the image captured by the camera unit 120 , and analyzes the doubling time of the floating water plants based on the calculated area of ​​the floating water plants.

[0097] In step S430, the control unit 130 analyzes the harvesting cycle and the amount of one harvest of the floating aquatic plants based on the analyzed doubling time of the floating aquatic plants.

[0098] In step S440, the control unit 130 determines whether it is the harvesting period of the analyzed floating aquatic plants. If it is the harvesting period of the floating aquatic plants, step S450 is performed, otherwise, the process returns to step S410.

[0099] In step S450, the control unit 130 controls the nutrient solution supply unit 140 or the harvesting pump 310 to harvest the floating aquatic plants in an amount equivalent to the one-time harvest amount of the floating aquatic plants.

[0100] Specifically, the control unit 130 analyzes the image taken by the camera unit 120 and controls the nutrient solution supply unit 140 until the change in the floating aquatic plants in the cultivation bed 111 caused by the floating aquatic plants discharged through the discharge pipe 114 corresponds to the analyzed one-time harvest amount, so that the nutrient solution is supplied to the cultivation bed 111 and 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 large-capacity discharge pipe 115, so that the floating aquatic plants on the surface of the nutrient solution flow into the nutrient solution through the discharge pipe 114 and move toward the harvesting unit 150 connected to the discharge pipe 114, and the floating aquatic plants are harvested; or the harvesting pump 310 is controlled so that after sucking in the nutrient solution and floating aquatic plants on the surface of the cultivation bed 111, the nutrient solution and floating aquatic plants are discharged to the discharge pipe 114, so that the floating aquatic plants can be harvested.

[0101] Although the embodiments of the present invention are described above, they are only illustrative.
