Description

3D spatial information database trading system {Complex 3d area information database trade system}

The present invention relates to a 3D spatial information database transaction system. Specifically, the present invention relates to a transaction system and a transaction method for evaluating and providing the technical value of spatial information photographed by a drone between a consumer and a supplier.

The geospatial data industry is the core of the 4th industrial revolution, and the geospatial data market is expected to grow rapidly to 15 trillion won in 2020, and the Ministry of Land, Infrastructure and Transport is establishing a vision plan to create a new geospatial data convergence industry and to strengthen the capabilities of spatial enterprises.

A representative example of the spatial information industry is acquiring land and sea information such as land, roads, city areas, mountains, forests, and the sea as maps, that is, maps. For this purpose, unmanned aerial vehicles such as drones, aircraft or vehicles dedicated to taking maps, or smartphones or tablets are being used. Core data of spatial information is an image including location information.

However. Even if a fast-operating drone is used to acquire image information, there is a disadvantage in that it takes a lot of time and money due to labor costs, actual expenses, and drone rental fees. Therefore, it is very difficult for the consumer to create a map by himself. In the case of a supplier who is a map creator, it is common to provide a customized map according to the ordering requirements such as companies or public institutions. However, since detailed requirements are different for each consumer, it is cumbersome, and there is a time difference in order to meet different ordering requirements, but there are cases where a wide range of the same or overlapping areas are repeatedly filmed. After acquiring image data, it takes a lot of time to deliver the result, and verification of image data also requires mutual effort. As a result, it is cumbersome and takes a long time to trade spatial information 1:1 between a consumer and a supplier, and it is particularly difficult to update and maintain spatial information.

If so, it would be convenient if spatial information including a large number of image data and 3D mapping information could be sold as a product by creating a trading platform between the consumer and the supplier. It can contribute to the development of the national industry by encouraging many geospatial data companies to participate.

As a patent for acquiring map information using a drone as an unmanned aerial vehicle, for example, Patent No. 10-2159134 performs calibration to obtain correction data for a camera, and uses the correction data to Disclosed is content of generating an orthogonal map by controlling a camera to perform lens and tangential distortion correction and orthogonal correction. Patent No. 10-1990886 discloses that the drone IoT server operates as a relay server for communication connection between the smart drone and the ground control system, receives drone flight information and camera images from the smart drone, and delivers it to the ground control system, and furthermore, the space Disclosed is the creation of a plurality of flight routes of smart drones according to preset criteria in conjunction with a database that stores information big data. However, these patents are for correcting images taken by drones or operating drones for specific purposes.

As a patent related to the map sales system, there is, for example, Patent No. 10-0612429 on "a system and method for providing map information/additional information using a location-based service". This patent discloses that a DB including map information and additional information is built, and when a consumer purchases a map, a map-related information sales server contains an authentication key and encrypts the map and transmits it. However, since this patent focuses on the security of map encryption and transmission, and does not consider the map creation and provision method, it also discloses the evaluation of the value by analyzing the properties of the map, and also discloses the map selection criteria of consumers. not doing

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a block diagram of a 3D spatial information database transaction system (hereinafter referred to as "transaction system: 1) of the present invention. The transaction system 1 includes a transaction server 2, a consumer 4, and a supplier 6. These are connected via "spatial information" with the transaction server 2 as the central, but the consumer 4 and the supplier 6 are not directly connected.

Consumers 4 are individuals and companies that require spatial information, such as public institutions, construction companies, and surveying companies. For example, companies that use spatial information such as Google, Naver, Daum, and Kakao, Korea Land Information Corporation, Korea Land and Housing Corporation, Korea Executives Promotion Agency, Ministry of Land, Infrastructure and Transport, and public institutions using spatial information such as Korea Forest Service, drone manufacturers, mapping equipment Manufacturers, drone insurance companies, and other individuals who need spatial information. They request spatial information data from the transaction server 2, and purchase and use the data.

The provider 6 is a subject that produces and transmits spatial information. In order to use drones, organizations or companies with drone licenses are desirable. In this case, idle or latent drone license holders can be utilized as personnel to effectively create jobs. The operating entity of the transaction server 2 may serve as all or part of the business of the supplier 6 . However, logically, as in FIG. 1 , the transaction server 2 is illustrated to be distinct from the provider 6 .

The transaction server 2 , the consumer 4 , and the provider 6 may be connected to any type of wireless network or wired network, and are not limited thereto. In addition, they can use any electronic device such as a computer, PDA, tablet, or mobile phone for communication and transaction work.

2 is a block diagram of the transaction server 2 of the present invention. The transaction server 2 is largely composed of a spatial information database creation platform 20 and a management platform 22 . The creation platform 20 mainly creates and displays spatial information to be sold to the consumer 4 . The management platform 22 stores the information of the consumer 4 and the supplier 6, orders a job from the supplier 6 if necessary, and proceeds with payment when the spatial information is sold.

First, the spatial information database generation platform 20 will be described.

The generating platform 20 includes an image storage DB 200 , a value evaluation module 202 , a spatial information DB 204 , and a spatial information DB display unit 206 . The provider 6 logs in to the transaction server 2 and uploads the image data it has acquired. The image storage DB 200 stores image information of a specific area transmitted by the provider 6 . Image information is sorted and stored in the order of supplier and/or region and reception time to expedite data processing.

The value evaluation module 202 determines the value of the product in consideration of the unique attributes associated with each image. This is a service for providing image data including GPS and location information. For objective value evaluation, the price of equipment required to acquire an image including location information, the moving range of the place, the weather, the difficulty of shooting, etc. are considered as parameters. In addition, since various properties of image data including location information have different economic values, required equipment is different, and shooting environments are different, weights are differentially assigned to each parameter.

Table 1 shows examples of parameters and weights of the present invention.

parameter weight evaluation score Location information (GPS) 10 Jeju (10), Gangwon (9), Gyeongnam (8),..., Gyeonggi (3), Seoul (2) Altitude 9 150m(9), 140m(8),....., 60m(1) camera type 8 5D MARK series(8), DJI Phantom(7),., DJI Matrix(4) shutter speed 7 1/360(7), 1/120(5),...1/30(1) ISO (sensitivity) 6 100(6), 200(5),....., 1600(2) aperture number 5 f/2.4(5), f/2.8(4), f/4.0(3), f/5.6(2) resolution 4 4608*3456(4), 3840*2160(3), ...1280*720(2)

In Table 1, the weight of location information is determined in consideration of environmental conditions such as moving distance, average wind speed in the area during the shooting period, and wind direction. The weight of the altitude is given as the higher the altitude, the stronger the wind speed and the higher the difficulty of shooting. Cameras give a lot of ratings to expensive equipment. The lower the shutter speed, the better without blurring, so a larger value is given to a lower value. The lower the ISO (sensitivity), the less noise in the image. The lower the aperture, the better the image quality. The higher the magnification, the sharper the resolution. Of course, Table 1 shows an example of parameters and weights, and various additions and modifications are possible here.

In addition, as will be described later, since the above is the attribute value value of one image, the value evaluation module 202 determines this price with the total number of images (assuming that the attributes of all images supplied by the provider are the same) and a predetermined value. Multiply the base price of one image to determine the total product price. The basic price can be recorded and updated by the manager of the transaction server 2 as an average cost when a basic image is provided in consideration of the flow of the spatial information market.

3 is a flowchart showing the operation of the valuation module 202 of the present invention.

First, the valuation module 202 checks the integrity of the image transmitted by the provider 6 (S10). For example, the type, size, and location information of the file conforming to the standard, verification of the supplier code, authentication, and virus check, etc.

Next, attribute information is extracted from the image (S12). "Attribute information" includes image itself attributes, premium attributes, location information characteristics, and camera attributes. The image itself attributes are attribute information directly related to the image, such as photo size, bit level, and resolution. Premium attributes are focused or multi-angle shots of a specific image, such as the rarity of the photo, the degree of overlap, and the number of connected images. Location information characteristics are latitude, longitude, and altitude information provided by GPS. Camera properties are camera model, ISO, exposure value, shutter speed, etc. These attribute information can be extracted from the file information of the image data. However, not all attribute information extracted from the image becomes a parameter and weight is given, and elements identical to the information stored in the table set in advance in the value evaluation module 202 by the administrator are selected and become parameters.

Next, the valuation module 202 determines the product price of the image (S14).

For example, if the parameters, assignment values, and weights of attributes related to an image are as shown in Table 2

parameter Location information (GPS) Altitude camera type resolution the corresponding evaluation score Jeju Island (10) 80m(2) Parrot Anafi (5) 4608*3456(4) weight 10 9 8 4 Score*Weight 100 18 40 16

The product value based on the attributes of the image becomes (100 + 18 + 40 + 16 ) = 174. Here, assuming that there are 100 images of the same attribute provided by the provider, and the basic price of one image is 50 won,

174 × 100 × 50 = 87,000 (KRW) becomes the product price for the entire image provided by the supplier. The product price for one image is 174 × 50 = 8,700 (KRW).

Next, the value evaluation module 202 links or associates the product price data with the attribute data, such as parameters, which are the basis for determining the product price, to the image data and transmits it to the spatial information DB 204 (S16).

The spatial information DB 204, like the image storage DB 200, also sorts the data in the order of the supplier and/or region and the reception time.

In FIG. 2 , the spatial information DB display unit 206 of the present invention reads data recorded in the spatial information DB 204 and displays spatial information such as map or photo information on the display of the electronic device. 4 is a display example of spatial information, FIG. 4 (a) is one of 1502 photos taken 250 m above the ground of 1ha in the lowlands of Jeju Island with the "Parrot Disco Sequoia" device, and FIG. 4 (b) is the same Shown is one of 234 photos of the land taken with the "Parrot Anafi" device from 120 m.

The spatial information DB display unit 206 deletes and displays the weight-related attribute data associated with the image, so that the consumer 4 can check the spatial information and the product price. What the consumer 4 cannot see is product pricing related data including weights, parameters, and allocation values, and basic attribute information attached to the image file - resolution, camera type - can be checked. However, after the consumer 4 purchases the spatial information, it is desirable to improve the reliability of the product price by transmitting the product price data of the spatial information so that it can also be confirmed.

The spatial information DB display unit 206 may display spatial information in various ways, such as by region, by supplier, by price, by rating, and the like. Since all of these display methods are known, a detailed description thereof will be omitted.

After logging into the transaction server 2 through an electronic device, the consumer 4 can easily search for and select a map that he or she wants in a wide range in consideration of the price.

Next, the management platform 22 of the present invention will be described with reference to FIG. 2 again.

The management platform 22 includes a supplier management module 220 and. It includes a consumer management module 230 and a payment execution unit 240 .

The supplier management module 220 includes a supplier DB 222 and a supplier work request unit 224 . All information about the supplier 6 is recorded in the supplier DB 222 . The supplier work request unit 224, when the management server 2 is requested by the consumer 4, or the management server 2 actively holds other spatial information by reflecting the market conditions, the supplier 6 ) to order and transmit the necessary spatial information work.

The consumer management module 230 includes a consumer DB 232 and a consumer purchase record storage 234 . All information about the consumer 4 is recorded in the consumer DB 232 . The consumer purchase record storage unit 234 stores the spatial information purchase history of the consumer 4, and the consumer 4 accesses the transaction server 2 and logs in or searches for spatial information similar to that previously purchased after logging in. If you do, make sure to check your past history.

When the consumer 4 purchases spatial information, the payment execution unit 240 transmits an amount obtained by subtracting the deduction amount determined according to a predetermined ratio determined by the space server 2 from the sales amount to the account of the provider 6 .

In the present invention, the spatial information database creation platform 20 and the management platform 22 organically exchange information. For example, the image storage DB 220 and the spatial information DB 204 refer to the provider DB 222 to sort data. In addition, the spatial information DB display unit 206 displays the spatial information by referring to the supplier DB 222 , and reads and displays the records of the consumer purchase record storage 234 according to the click of the consumer 4 .

Accordingly, the transaction server 2 of the present invention can process and store image and spatial information data quickly and accurately, and large-capacity photo and picture files.

In the present invention, the transaction server 2 processes image data according to the order of the consumer 4 or evaluates the technology value, if necessary, as well as the sale or mediation of spatial information. In addition, it is possible to build a map database through learning through artificial intelligence using a lot of stored image data and provide a 3D mapping service that allows consumers to check a specific area without purchasing photos. In addition, it is possible to provide a variety of services for the general public as well as consumers by programming drone-related professional training, flight and filming agency services, and sales and rental of related equipment and services.

The above has described several preferred embodiments of the present invention, and various changes and modifications are possible with respect to the present invention. In particular, it should be noted that in the present invention, items and scores that are the criteria for attribute value evaluation can be variously changed according to the development of image processing technology and unmanned aerial vehicles.
