In the present invention, “garbage”, which is the target of source detection for services, is garbage floating in the water, and is located in the sea (or ocean, 310, 320, 330) as shown in Figure 2a. 331) and as shown in FIG. 2b, it may include all trash (351a, 351b, 351c) located on land and rivers (rives, rivers, etc.).

In the present invention, there are various types of trash, such as plastic bags, animal carcasses, wood, vegetation, household waste, and green algae, and there is no limit to the type (or type) of trash as long as it is floating in water. Below, for convenience of explanation, the term “floating waste” will be used to explain the method of providing source detection services for waste floating in water.

As shown in FIG. 1, the floating waste source detection service providing system 100 based on satellite data may include at least one of a communication unit 110, a storage unit 120, and a control unit 130.

The communication unit 110 communicates with at least one of the artificial satellite 10, the user terminal 20, and an external server (not shown), and receives overall information required for the floating waste source detection service providing system 100 based on satellite data. Or it can be made to transmit.

The communication unit 110 may receive satellite data from at least one of the artificial satellite 10 and an external server (not shown).

Satellite data described in the present invention is data acquired by a device (ex: imaging device, camera), sensor, etc.) mounted on the artificial satellite 10, for example, image data (or satellite image), It may include sensor data (altitude information of artificial satellites, sensor type information that acquired satellite data, wavelength information, frequency information, etc.). In the present invention, for convenience of explanation, a method of providing a floating waste source detection service based on satellite images is described, but it is not necessarily limited to satellite data, and a floating waste source detection service can be provided based on various satellite data.

Meanwhile, the communication unit 110 may receive satellite data through an external server (not shown). That is, the communication unit 110 can receive satellite data from the artificial satellite 10 using an external server (not shown) as a medium. However, hereinafter, for convenience of explanation, it will be described as receiving satellite data from the artificial satellite 10.

Furthermore, the communication unit 110 may transmit detected floating waste source information (or a report including the source information) to the user terminal 20 using satellite data.

Here, the user terminal 20 may be a fixed terminal implemented as a computer device or a mobile terminal, and may be understood as an electronic device. Examples of the user terminal 20 include smart phones, mobile phones, tablet PCs, computers, laptops, digital broadcasting terminals, Personal Digital Assistants (PDAs), and Portable Multimedia Players (PMPs). As an example, in FIG. 1, the user terminal 20 shows the shape of a smartphone, a laptop, and a computer, which are mobile terminals. However, in embodiments of the present invention, the user terminal 20 actually communicates through a network using a wireless or wired communication method. It may refer to one of a variety of physical computer devices that can communicate with other user terminals or servers.

Furthermore, the communication unit 110 can support various communication methods depending on the communication standard of the communicating device.

For example, the communication unit 110 supports wireless LAN (WLAN), wireless-fidelity (Wi-Fi), wireless fidelity (Wi-Fi) Direct, digital living network alliance (DLNA), wireless broadband (WiBro), and WiMAX ( World Interoperability for Microwave Access), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A), 5th Generation Mobile Telecommunication (5G) , Bluetooth™, RFID (Radio Frequency Identification), Infrared Data Association (IrDA), UWB (Ultra-Wideband), ZigBee, NFC (Near Field Communication), Wi-Fi Direct, Wireless USB (Wireless Universal) Serial Bus) technology may be used to communicate with the video equipment 200 and devices (including cloud servers).

Next, the storage unit 120 can be configured to store various information related to the present invention. In the present invention, the storage unit 120 may be provided in the floating waste source detection service providing system 100 itself based on satellite data. Alternatively, at least a portion of the storage unit 120 may refer to at least one of the cloud server 31 and the database 32. In other words, it can be understood that the storage unit 120 is a sufficient space to store information necessary for providing services based on detection of floating waste sources according to the present invention, and there are no restrictions on physical space. Accordingly, hereinafter, the storage unit 120, the cloud server 31, and the database 32 will not be separately distinguished, and all will be referred to as the storage unit 120. At this time, the cloud server 31 may mean “cloud storage.”

In the storage unit 120, at least one of satellite data received from the artificial satellite 10 and satellite information matched to the satellite data may be stored.

In addition, in the storage unit 120, management areas corresponding to areas in charge of collecting floating waste for each region may exist in a matching manner.

Here, the management area includes the land area and maritime area managed by the area. For example, as shown in Figure 2a, the management area is the area around the coast and includes an area within a certain range from the coast. can do. These management areas may correspond to areas subject to regional management.

In addition, “region” in the present invention can be understood as a department in charge related to the region, and can also be understood as a city, county, district, or organization (ex: local government) that has jurisdiction over the region. In the present invention, ‘region’ may also be referred to as ‘jurisdictional region’, ‘jurisdictional office’, ‘competent department’, etc.

In the storage unit 120, regional management areas within a preset range from the coast may be predefined.

In the present invention, the management area can be understood as the area around the coast, as shown in FIG. 2A, and as an area within a certain range from the coast. These detection areas may correspond to management areas subject to regional management.

In each region, it can play a role in collecting floating waste that is detected (or detected) within the management area. For example, floating waste 311 detected in the management area 310 of area A (300a) can be understood as an object of collection and management in area A (300a). For another example, floating waste 321 detected in the management area 320 of area B (300b) can be understood as an object of collection and management in area B (300b).

Furthermore, each region can play a role in collecting floating waste detected (or detected) in the management area. For example, area A (300a) manages (or collects) floating waste detected in the management area of self-government A, and area B (300b) manages floating waste detected in the management area of self-government B. (or collection).

In the storage unit 120, management areas and management areas 310, 320, and 330 may exist in matching regions (or regions or jurisdictions, 300a, 300b, and 300c). In addition, the control unit 130 may detect the source of floating waste by performing analysis on the management area and the detection area corresponding to the management area 310, 320, and 330 in the reference satellite data and reference satellite data. . Therefore, in the present invention, ‘detection area’, ‘management area’ and ‘management area’ can be used interchangeably.

Meanwhile, in order to reduce the amount of waste generated, solutions are needed at the source of waste. To this end, it is important for each region to determine the amount of waste generated in the area in charge.

However, waste can be moved to other areas by natural phenomena such as wind, ocean currents, and river flows. In this case, the origin of the waste is unclear and it is difficult to determine the amount and cause of waste generated by region (or region), so countries and regions are investing excessive manpower and money into waste reduction. Furthermore, waste movement can cause international disputes, disputes between neighboring regions, and issues of fairness in budget allocation.

For example, as shown in Figure 2 a, waste generated in area C (300c) flows into the management area of area C (330) due to wind, etc., and then travels to the management area (320) of area B or A via ocean currents. You can move to the local management area (310). When the waste 331 generated in area C 300c is detected in the management area 310 of area C, the amount of waste generated in area C and the waste to be collected in area C can be clearly specified. On the other hand, when waste generated in area C (300c) is detected in area B management area (320), it is difficult to determine which area among area C (300c) and area B (300b) the detected waste originated from. , it is difficult to specify the area responsible for collection.

Meanwhile, waste may enter a river (or stream, etc.) from land and then move to another area along the river. As shown in Figure 2b, in the case of South Korea, four major rivers including the Han River, Nakdong River, Geum River, and Yeongsan River flow, and waste can move from certain areas to other areas along these rivers. For example, waste 351a generated on land near the Han River basin may flow into the Han River and then flow into the Geum River or Nakdong River along the Han River. In this case, it is difficult to identify the source (place of generation) of the waste (351b) detected in the Geum River basin or the waste (351c) detected in the Nakdong River basin, making it difficult to specify the amount of waste generated by region (or region) and the waste to be collected.

Accordingly, the control unit 130 can detect the source of floating waste from satellite data received from the artificial satellite 10 and generate an analysis report for demand in the region based on the source detection result.

Meanwhile, regions may be divided based on region. For example, region A is a region responsible for region A (300a), region B is a region responsible for region B (300b), and region C is a region responsible for region C. It may be an area in area 300c. Accordingly, in the present invention, each region and each region can be described interchangeably, and the same reference numerals can be assigned. For example, both regions A and A are described using the reference numeral '300a', both regions B and B are described using the reference code '300b', and both C and C regions are described using the reference code '300b'. It can be explained by giving '300c'.

As shown in FIG. 2, the control unit 130 performs analysis on the management area matched to each of the plurality of regions in the satellite data 300 to determine the management area of a specific region (ex: region A, 300a). By confirming which area among the plurality of management areas the floating waste to be tracked (311) existing in 310 is located, the source of the floating waste to be tracked (311) can be detected.

Floating waste 331 generated in area C (300c) may flow into the management area 330 of area C and then move to the management area 320 of area B according to the ocean current. In the management area 320 of area B, floating waste generated in area B 300b and floating waste generated in area C 300c may be present. Additionally, the floating waste 321 present in the management area 320 of area B may move to the management area 310 of area A according to the ocean current. And, in the management area 310 of area A, floating waste generated in area A (300a), floating waste generated in area B (300b), and floating waste generated in area C (300c) may coexist.

Based on a plurality of satellite data captured at different times, the control unit 130 determines in which area the floating waste 311 existing in the management area 310 of area A is generated and the management area 310 of area A It is possible to detect whether the floating waste 311 has flowed into the system or the source of the floating waste 311.

In addition, the control unit 130 can use the detection results of the source of floating waste to generate basis data for establishing efficient countermeasures against floating waste and provide it to consumers in countries, regions, etc.

Below, a method for detecting the source of floating garbage will be described in detail based on a plurality of satellite data captured at different times.

In the present invention, a process of specifying floating garbage to be tracked from reference satellite data captured at a reference point can be performed (S310, see FIG. 3).

As shown in FIG. 4, the control unit 130 selects the floating garbage 401 to be tracked from the reference satellite data 400 captured at the reference time (T0) among the plurality of satellite data received through the communication unit 110. It can be specified.

The control unit 130, in the reference satellite data 400, tracks a floating waste cluster located in the management area 310 matched to a specific area (e.g., area A, 300a) among the plurality of areas, and floating waste to be tracked ( 401).

In the present invention, ‘floating trash to be tracked’ can be understood as floating trash that is subject to source detection.

Here, the ‘source of floating waste’ can be understood to include at least one of the floating waste generation site (or source), cause of occurrence, time of occurrence, and amount (or volume) of generation.

And, in the present invention, the floating waste generation site (or source) may refer to the area where floating waste is generated or the area managed by the area. Therefore, in the present invention, floating waste ‘source’, ‘generation area’, ‘generation area’, ‘source’, ‘source area’ and ‘source area’ can all be used interchangeably.

Meanwhile, the control unit 130 can determine the reference point (T0) for specifying floating waste to be tracked in various ways. Specifically, the control unit 130 may determine a time point corresponding to at least one of occurrence of a floating waste source detection event, occurrence of a disaster event, and user request according to satellite data monitoring as the reference time point T0.

Based on the occurrence of a floating waste source detection event that is determined to require floating waste source detection from the satellite data while monitoring satellite data, the control unit 130 sets the point of occurrence of the floating waste source detection event as a reference time (T0). It can be specified.

When the control unit 130 detects (or detects) a predefined event condition from satellite data, it may determine that a floating waste source detection event has occurred. For example, when the control unit 130 detects floating waste exceeding a certain volume from satellite data or detects a specific type of floating waste (ex: household waste, factory waste, etc.), a floating waste source detection event is generated. It can be determined that has occurred. When the occurrence of a floating waste source detection event is detected, the control unit may determine the event occurrence time as the reference time (T0).

Furthermore, the control unit 130 may specify the point in time when the disaster event occurred as the reference point in time (T0). The disaster event on which the reference point (T0) is based can vary. For example, the control unit 130 may operate on a natural disaster event (ex: typhoon, flood, earthquake, volcanic eruption), accident event (ex: ship collision accident, ship sinking accident, ship fire accident, etc.), landfill event, waste When at least one of a spill event (or wastewater spill event or chemical spill event) or construction event (ex: reclaimed land construction, building construction, etc.) occurs, the event occurrence point can be determined as the reference time point (T0).

Furthermore, the control unit 130 may specify the reference point in time (T0) based on a user request. When the control unit 130 receives a request to detect the source of floating waste based on a point in the past from the user, it may specify the point in the past as the reference point in time (T0). In addition, when the control unit 130 receives a request to detect the source of floating waste based on a point in the future from the user, the control unit 130 may specify the arrived point in the future as a reference decision based on the arrival of the point in the future. .

Meanwhile, the control unit 130 may extract (specify or determine) satellite data captured at a reference point in time (T0) as reference satellite data 400. In this case, the control unit 130 may extract (specify or determine) satellite data captured around a specific area as reference satellite data. For example, when it is necessary to detect the source of floating waste existing in the management area 310 of area A (300a), the control unit 130 includes (centered on) the management area 310 of area A (300a). ) Satellite data can be extracted (specified or determined) as reference satellite data 400.

Next, in the present invention, a process of determining a past time point for detecting the source of floating waste to be tracked may be performed based on the reference point (S320, see FIG. 3).

As shown in FIG. 4, in order to specify reference images 410 and 420 to be compared with the reference satellite data 400, the control unit 130 uses at least one past image based on the reference time T0. The time point (T1, T2) can be determined. In the present invention, for convenience of explanation, the plurality of past points in time (T1, T2) may be named as a first past point in time (T1) and a second past point in time (T2) based on the reference point in time (T0).

The control unit 130 may determine each of the plurality of past times T1 and T2, or determine a representative past time point, and then further specify times between the representative past time point and the reference time point T0 as past times. For example, the control unit 130 may determine the second past time point (T2) as a representative past time point and further specify the first past time point (T1) that exists between the second past time point and the reference time point (T0). there is.

Meanwhile, the control unit 130 can determine past times T1 and T2 in various ways. Specifically, the control unit 130 may determine a past point in time based on at least one of previous monitoring history, disaster event occurrence, user request, and reference satellite data.

If there is monitoring data for detecting the source of floating waste before the reference time T0, the control unit 130 may determine the time point after monitoring as the past time point.

The monitoring data may refer to satellite data used to detect floating waste sources. The control unit 130 may determine the time after the most recently captured satellite data among the satellite data used to detect the source of floating debris before the reference time T0 as the past time. In this case, the past time point can be understood as a representative reference past time point (T2).

Furthermore, the control unit 130 may determine the occurrence time of a disaster event that occurred before the reference time T0 as a time in the past.

As described above, the control unit 130 may also determine the reference point based on the time when the disaster event occurs. In this case, the control unit 130 may determine a reference time and a past time based on the occurrence time of each different disaster event. For example, the control unit 130 may determine the occurrence time of the first disaster event as a reference time, and determine the occurrence time of the second disaster event, which is different from the first disaster event, as a past time.

Furthermore, if there are multiple disaster events that occurred before the reference time T0, the control unit 130 may determine each of the occurrence times of the plurality of disaster events as a past time point. For example, when the first disaster event and the second disaster event each occur before the reference time T0, the control unit 130 determines the occurrence time of the first disaster event as the first past time point T1, The occurrence point of the second disaster event may be determined as the second past time point (T2).

Furthermore, if there is a user request time point that specifies a time point before the reference time point (T0), the control unit 130 may determine the user request time point as a past time point (T1, T2).

Furthermore, the control unit 130 may specify a past point in time based on the floating garbage 401 to be tracked specified in the reference satellite data 400. For example, the control unit 130 controls the surrounding marine environment (ex: weather, current direction, speed, etc.) related to the floating waste to be tracked (401) specified in the reference satellite data 400, and the floating waste to be tracked (401). Based on at least one of the type, volume (or the size of the area occupied by the object corresponding to floating debris in the reference satellite data), and disaster event that occurred around the ocean, past points in time (T1, T2) can be specified.

Meanwhile, the control unit 130 can specify a plurality of past points in time (T1, T2). There may be various methods for specifying multiple past points in time (T1, T2). For example, the control unit 130 may specify a plurality of past time points T1 and T2, respectively, based on the above-described past time point specification criteria. For another example, the control unit 130 may specify a past time point (T1) that is different from the representative past time point (T2) between the reference time point (T0) and the representative past time point (T2). In this case, the representative past time point may correspond to the past among a plurality of past times T1 and T2. In the present invention, when a plurality of past points in time (T1, T2) are specified, they can be described by naming them as the first past point in time (T1) and the second past point in time (T2) in the order of proximity to the reference point in time (T0). .

Next, in the present invention, from reference satellite data captured at a time in the past, a process can be performed to detect in which area of the plurality of management areas matched by region the floating waste to be tracked is located (S330, see FIG. 3). .

As shown in FIG. 4, in the present invention, satellite data 400 captured at a reference point in time (T0) and satellite data 410 and 420 captured at past times (T1 and T2) are used to track a target. The source of floating waste 410 can be detected.

In the present invention, in order to avoid confusion in terminology, satellite data captured at a reference time (T0) is referred to as reference satellite data 400, and satellite data captured at past times (T1, T2) are referred to as reference satellite data 410, 420). In the present invention, 'reference satellite data' can be used interchangeably with 'past satellite data' and 'comparison satellite data', and the satellite data captured at the first past time point (T1) is used as the first past image 410. The satellite data captured at the second past time point T2 may be named the second past image 420.

On the other hand, when the reference satellite data 400 and the reference satellite data 410 and 420 are determined, the control unit 130 determines the tracking target floating garbage ( 401) can perform a process to detect the source.

The control unit 130 may perform analysis on a preset detection area in the reference satellite data 400 and reference satellite data 410 and 420.

In the present invention, the detection area can be understood as the area around the coast, as shown in FIG. 2, and as an area within a certain range from the coast. These detection areas may correspond to management areas subject to regional management.

In each region, it can play a role in collecting floating waste that is detected (or detected) within the management area. For example, floating waste 311 detected in the management area 310 of area A (300a) can be understood as an object of collection and management in area A (300a). For another example, floating waste 321 detected in the management area 320 of area B (300b) can be understood as an object of collection and management in area B (300b).

In the storage unit 120, management areas 310, 320, and 330 may exist in matching regions (or regions or jurisdictions, 300a, 300b, and 300c). In addition, the control unit 130 may detect the source of floating waste by performing analysis on the detection area corresponding to the management area 310, 320, and 330 in the standard satellite data and reference satellite data. Accordingly, in the present invention, ‘detection area’ and ‘management area’ may be used interchangeably.

The control unit 130 may perform analysis to detect the source of floating waste to be tracked only for an area corresponding to the management area in the reference satellite data 400 and the reference satellite data 410 and 420. Hereinafter, even if there is no separate explanation, it can be understood that the control unit 130 performs floating waste source detection analysis to be tracked for floating waste only for the area corresponding to the management area in the satellite data.

Meanwhile, the control unit 130 generates reference satellite data (410, From 420), floating garbage forming a similar shape, color, and cluster as the tracking target floating garbage 410 can be detected.

The control unit 130 may perform similar image analysis on the reference satellite data 400 and the reference satellite data 410 and 420 using at least one image processing algorithm (e.g., object analysis algorithm). .

Here, similar image analysis is a variety of analysis methods that analyze images based on similarity. For example, it may be a method of analyzing the similarity of images through a method of matching corresponding feature points between a plurality of images.

The control unit 130 may perform similar image analysis on the reference satellite data 400 and the reference satellite data 410 and 420 using a similar image analysis algorithm that performs machine learning.

And, based on the similar image analysis result, the control unit 130 corresponds to at least a portion of the floating garbage 401 to be tracked specified in the reference satellite data 400 and at least one of shape, color, type, and cluster type. Floating garbage (or floating garbage object) can be detected from the reference satellite data 410 and 420.

Meanwhile, the control unit 130 may detect which management area the floating waste detected in the reference satellite data 410 and 420 was located in among the plurality of management areas matched to each of the plurality of regions.

For example, as shown in FIG. 4, the floating waste group 401 to be tracked located in the management area 310 of area A 300a includes the first floating waste 401a and the second floating waste 401b. and the third floating waste 401c.

Here, the first to third phase floating waste 401a to 401c are floating waste groups classified according to floating waste types (or properties) with at least one of shape, shape, color, type, and group type different. It can be understood.

The first floating waste 401a is a cluster of floating waste of the first type, the second floating waste 401a is a cluster of floating waste of a second type different from the first type, and the third floating waste ( 401c) can be understood as a cluster of third type floating waste different from the first and second types.

The control unit 130 is located in the management area 320 of area B 300b in the first reference satellite data 410 through similar image analysis of the reference satellite data 400 and the reference images 410 and 420. The second floating waste 401b and the third floating waste 401c can be detected. Additionally, the control unit 130 may detect the third floating waste 401c located in the management area 330 of area C 300c from the second reference satellite data 420.

The control unit 130 may detect that the second floating garbage 401b was located in the management area 320 of area B 300b at the first past time point T1, based on the similar image analysis result. . And, the control unit 130 determines that the third floating waste 401c is located in the management area 320 of area B 300b at the first past time T1, and area C at the second past time T2 ( It can be detected that it was located in the management area 330 of 300c). Additionally, the control unit 130 may detect that the first floating waste 401a is not located in any management area other than the management area 310 of area A 300a.

Next, based on the detection results, a process may be carried out to determine the area matched to the management area where the floating waste to be tracked was located as a related area related to the source of the floating waste to be tracked (S340, see FIG. 3 ).

As a result of similar image analysis of the reference satellite data 400 and the reference images 410 and 420, the control unit 130 determines that the floating waste 401 to be tracked is in area A (300a) and area B (300b) among a plurality of areas. ) and Area C (300c), respectively, based on being located in the management areas (310, 320, 330), Area A (300a), Area B (300b), and Area C (300c) can be determined as related areas. there is.

Meanwhile, the control unit 130 determines the movement path (or tracking path) and source (or origin) of the floating waste to be tracked (401) based on the detection results of the management area where the floating waste to be tracked (401) was located. It can be estimated (or tracked or predicted).

For example, the control unit 130 may estimate that the first floating waste 401a was generated in area A (300a) and flowed into the management area 310 of area A (300a). And, the control unit 130 generates the second floating waste 401b in area B (300b) and flows into the management area 320 of area B (300b), and then flows into the management area 310 of area A (300a). It can be assumed that it moved to . And, the control unit 130 generates the third floating waste 401c in area C 300c and flows into the management area 310 of area C 300c, and then flows into the management area 320 of area B 300b. It can be assumed that it moved to the management area 310 of area A (300a).

Meanwhile, as described above, the control unit 130 may perform similar image analysis only for predefined regional management areas in the reference satellite data 400 and the reference satellite data 410 and 420.

This management area may be predefined and exist within a preset range from the area where land and sea meet.

The control unit 130 performs similar image analysis only on areas corresponding to a preset range from land in the reference satellite data 400 and reference satellite data 410 and 420, and performs similar image analysis on areas that do not correspond to the preset range. Similar image analysis may be limited.

The control unit 130 limits similar image analysis to areas that do not correspond to the preset range, so even if floating garbage exists in areas other than the management area (for example, see reference numeral '340' in FIG. 4), The floating waste may not be identified (or detected) as the tracking target floating waste 401, and the area 340 where the floating waste exists may not be determined as the area where the floating waste was located (i.e., the source). there is.

Meanwhile, the control unit 130 may generate and provide a report for demand in the region, etc., based on the result of detecting the source of the floating waste 401 to be tracked. In this case, the control unit 130 generates a report (or writing) can be done. Below, we will sequentially explain the detection result report for the area that requested floating waste source detection, the floating waste measure report based on floating waste source detection, and the budget distribution basic data report.

In this case, the processed satellite data 510 may be satellite data that is processed based on the management area 310 of a specific area (ex: area A, 300a) using reference satellite data captured at a reference point in time.

In addition, the control unit 130 may include detection status information of floating waste to be tracked detected in the management area 310a of a specific area (ex: area A, 300a) at the reference point in the detection result report 500. there is.

For example, the detection status information includes i) detection date information (or reference point information or past point information ex: 2022-12-12) of the detected floating waste, and generation amount information (or detection amount) of the detected floating waste to be tracked. Information, ex: 150 tons), and information on the type of floating waste to be tracked (ex: plastic bottles, plastic bags, fishing supplies, industrial packaging, etc.). Meanwhile, the above-mentioned detection status information is only an example, and the control unit 130 detects various detection status information about floating waste to be tracked detected in the management area 310 of a specific area (ex: area A, 300a). It can be included in the results report 500.

(401a to 401c) Each movement path (or tracking path), occurrence area (or source area), and related area information may be included in the detection result report 500.

For example, although not shown, the control unit 130 determines that, based on the source detection result of the first floating waste 401a included in the tracking target floating waste 401, the first floating waste 401a is, Guidance information indicating what has occurred in the management area 310a of a specific area (ex: area A, 300a) may be included in the detection result report 500.

For another example, the control unit 130 determines that the second floating waste 401b is located in a specific area (ex: area A) based on the source detection result of the second floating waste 401b included in the floating waste 401 to be tracked. , Guidance information indicating that the detection occurred in a management area 320 in a different area (ex: area B, 300b) than 300a) may be included in the detection result report 500. Specifically, the control unit 130 sends a second message to the management area 320 of another area (ex: area B, 300b) so that the user (or area A) intuitively recognizes the source of the second floating waste 401b. Satellite data 520 on the location of floating waste 401b may be included in the detection result report 500. And, the control unit 130 displays the movement path of the second phase floating waste 401b (the movement path from the management area '320' of the B support car to the management area '310' of a specific area) on the satellite data 530. can do.

As another example, the control unit 130 determines that the third floating waste 401c is different from area B based on the source detection result of the third floating waste 401c included in the tracking target floating waste 401. Information indicating that the management area 330 of the area (ex: area C, 300c) has occurred may be included in the detection result report 500. And, the control unit 130 positions the third floating waste 401c in the management area 330 of area C 300c so that the user (or region) intuitively recognizes the source of the third floating waste 401c. Satellite data 540 may be included in the detection result report 500. The control unit 130 may display the movement path of the third floating waste 401c (the movement path from management area ‘330’ of region C to management area ‘310’ of a specific region) on the satellite data 550.

Furthermore, the control unit 130 may include information on the amount (or volume) of floating waste generated for each relevant region in the detection result report 500. The control unit 130 estimates (or calculates or calculates) the amount of floating waste generated (or volume) in each of a plurality of different regions related to floating waste to be tracked, and calculates the calculated amount (or volume) of floating waste for each relevant region, It can be included in the detection result report 500.

The control unit 130 may estimate (calculate or calculate) the amount (or volume) of floating waste generated for each relevant region based on the reference satellite data 400 and the reference satellite data 410 and 420. For example, the control unit 130 estimates (calculates or calculates) the amount of floating waste generated (or volume) in the relevant area from reference satellite data in which the tracking target floating waste 401 is located on the management area of the relevant area. You can.

Furthermore, the control unit 130 may include the estimated collection cost for collecting floating waste generated in each relevant area in the detection result report 500. The control unit 130 may include in the detection result report 500 satellite data displaying estimated collection cost information for floating waste generated in each region around each relevant region.

For example, as shown in FIG. 5, the control unit 130 calculates the estimated collection cost (ex: '2) of the second floating waste to be tracked (401b) generated in the first related area (ex: B area, 300b). billion') information, satellite data 560 displayed around the first related area (ex: area B, 300b) may be included in the detection result report 500.

(ex: Area C, 300c) Satellite data 570 displayed in the vicinity can be included in the detection result report 500.

Furthermore, the control unit 130 calculates the estimated collection cost of floating waste to be tracked in a specific area (ex: area A, 300a) and the estimated collection cost of floating waste to be tracked in another area (ex: area B, 300b). It can be predicted (calculated, calculated, or estimated) and included in the detection result report 500. More details will be provided later.

Meanwhile, the control unit 130 may specify an area of interest with a high frequency of floating waste generation (or detection frequency) based on the detection result of the floating waste source to be tracked. Meanwhile, the area of interest described in the present invention may mean an area that manages a specific area. Accordingly, in the present invention, a region of interest can also be understood as a region of interest.

In this case, the control unit 130 may specify an area with a high frequency of floating waste generation (or detection frequency) as an area of interest based on a plurality of monitoring results.

Here, the plurality of monitoring results may mean a plurality of satellite data, similar image analysis results, and source detection results for detecting the source of floating waste to be tracked. In addition, the plurality of monitoring results may mean data (satellite data, similar image analysis results, and source detection results) for each of a plurality of different floating wastes to be tracked.

A plurality of monitoring results may be stored in the storage unit 120, and the control unit 130 selects an area of interest with a high frequency of occurrence (or detection frequency) of floating waste based on the plurality of monitoring results stored in the storage unit 120. It can be specified.

Meanwhile, when floating waste to be tracked is detected in the management area of a specific area, the control unit 130 may determine that floating waste has been detected in the specific area.

In contrast, when the source of the floating waste to be tracked is determined to be a specific area, the control unit 130 may determine that the floating waste was generated in the specific area.

That is, the control unit 130 specifies the area matched to the management area with a high detection frequency of floating waste to be tracked as an area with a high frequency of detection of floating waste, and selects the area with a high frequency determined as the source of floating waste to be tracked as floating waste. Areas of interest with a high frequency of waste generation can be identified.

Below, for convenience of explanation, an area with a high ‘frequency of floating waste generation’ will be explained as an example of an area of interest that is the subject of a countermeasure report. However, the report on measures for areas with a high ‘frequency of floating waste generation’ described below is equally applicable to the report for areas with a high ‘frequency of floating waste detection’.

Meanwhile, the control unit 130 may specify an area of interest with a high frequency of floating waste generation based on the floating waste source detection results (or monitoring results) stored in the storage unit 120.

Can be determined (or specified) by self-control with high frequency of interest

For another example, the control unit 130 may, based on the floating waste source detection results (or monitoring results) stored in the storage unit 120, match a person to a management area with a high number of detections of floating waste in a preset order. It can be determined (or specified) as a local area of interest with a high frequency of floating waste generation.

And, as shown in (b) of FIG. 6, the control unit 130 can generate (or write) a floating waste countermeasure report 600 for area A (300a).

The control unit 130 may analyze the cause of floating waste for the area of interest based on the floating waste source detection results in order to generate a countermeasure report for the area of interest. For example, if floating trash is generated based on a disaster event that occurs in an area of interest, the controller 130 may analyze the disaster event as the cause of floating trash for the support vehicle of interest. For another example, when floating waste generated in another area flows into the management area of the area of interest, the control unit 130 may analyze the inflow of floating waste as the cause of floating waste in the area of interest.

When a prevention facility is installed in an area of interest (ex: area A, 300a), the control unit 130 determines the management area 310 of the area of interest (ex: area A, 300a) from satellite data captured after installation of the prevention facility. Detection (or detection) of floating waste can be performed.

In addition, the control unit 130 performs analysis on at least one of the amount (or volume), cause, type, and type of detected floating waste, and determines whether floating waste is floating after installing a prevention facility in the area of interest (ex: Area A, 300a). Monitoring can be conducted to determine whether waste has been reduced.

Based on the results of monitoring whether floating waste has been reduced, the control unit 130 compares the amount of floating waste detected in the management area of the area of interest (ex: A area, 300a) before and after the installation of the prevention facility, and compares the amount of floating waste detected in the management area of the area of interest (ex: A area, 300a). In the region, 300a), a report can be generated (or written) on whether the generation of floating waste has decreased after the installation of prevention facilities. For example, as shown in (b) of FIG. 6, the control unit 130 detects floating waste based on the time of installation of the prevention facility in the management area 310 of the area of interest (ex: area A, 300a). A graph comparing the generation amount can be included in the countermeasure report 600.

In addition, the control unit 130 may transmit the countermeasure report 600 to the area of interest (or area of interest account or area of interest terminal) where prevention facilities are installed.

Meanwhile, the present invention can provide a service that generates and provides information that can be used for basic data on regional budget distribution based on the detection results of floating waste sources. Below, information provision services that can be used for budget distribution basic data will be explained in detail.

In the storage unit 120, floating waste detection result information for each region with matching floating waste detection results may be stored and present in a plurality of regions.

The floating waste detection result information for each region may include information corresponding to various detection items. Various detection items include, for example, detection date when floating waste was detected by local government (e.g., baseline and past time points), satellite data used to detect floating waste, date of occurrence when floating waste is estimated to have been generated, It must include at least one of the following: cause of floating waste generation, floating waste generation site (or source), related area related to the source of floating waste, amount of floating waste generated (or detection amount), type of floating waste, and movement route (or tracking route) of floating waste.

That is, the control unit 130 can efficiently manage the floating waste detection results by managing the floating waste detection results for each region based on at least one of a plurality of items.

For example, the control unit 130 may manage the floating waste detection result information for each region by matching information on the cause and amount of floating waste generation for each region.

Meanwhile, the control unit 130 calculates (or calculates or estimates) the amount of floating waste generated by region over a certain period of time (e.g., yearly) based on the regional floating waste detection result information stored in the storage unit 120. You can.

The control unit 130 may estimate (calculate or calculate) the expected floating waste collection cost for each region based on the calculated amount of floating waste for each region.

Meanwhile, the control unit 130 may estimate (calculate or calculate) the expected collection cost of floating waste for each region based on at least one of the source (or generation point) and destination of floating waste.

The control unit 130 may estimate the expected cost of collecting the first type of floating waste for each region based on the source of the floating waste, and estimate the expected cost of collecting the second type of floating waste for each region based on the destination of the floating waste. .

Furthermore, the control unit 130 may compare the first type of floating waste collection cost and the second type of floating waste collection cost for each region to obtain information on an increase or decrease in the floating waste collection cost for each region according to the movement of floating waste. .

For example, as shown in (a) of FIG. 7, assume that some 701 of the floating waste generated in area B (300b) flows into the management area 310 of area A (300a).

As shown in (b) of FIG. 7, the control unit 130 predicts the first type of floating waste for area A (300a) based on the floating waste 711 whose source is area A (300a). Collection costs 712 can be estimated. In addition, the control unit 130 calculates the estimated collection cost of the second type of floating waste for area A (300a) based on the floating waste (711 and 701') whose destination is area 310 of area A (300a) ( 713) can be estimated.
