System for Providing History Information using Location Based Information Service and the Method}

The present invention relates to a system and method for providing historical information using a location-based information service. More particularly, the present invention relates to an augmented reality technology of a past image of a specific object registered at a point adjacent to each user's location by using a location-based information service. It provides a combination of the current video by using it, enables people to take a picture of the background with the combined video and share it through social network services (SNS) to secure a variety of content, the time and place you want In the past, you can easily check past images and historical facts of multiple targets in real time on the go, and open the development tool (Software Development Kit, SDK) for this to induce the participation of 3rd party developers through open development tools. Locators that enable the building of systems The present invention relates to a system and method for providing historical information using anti-information service.

Recently, due to the rapid development of information and communication technologies such as smart phones, the mobile terminal market is booming, and the development of applications using location based information service is continuously being made.

Location-based information service is a term used interchangeably with location-based service. Conventional location-based service provides location information around a user uniformly, whereas location-based information service selects only information selected by a user from location information around the user. There is a difference.

For example, the location-based service may include a friend search service, a card discount area search service, and the like, and the location-based information service may include a traffic information application service using augmented reality.

The technology using the location-based information service on the mobile platform has been studied in various fields. For example, Korean Patent No. 10-0834474, 'Item Location Management System in Ubiquitous Environment', includes an RFID tag and an information collection vehicle. It includes a GPS satellite, database server, RFID registration and management system, and location monitoring system. It is a technology that can provide the location of products produced at industrial sites in connection with user location.

However, even if the Korean Patent No. 10-0834474 selectively provides only information on a specific item selected by the user, it merely provides basic information of the corresponding item.

Moreover, a service for providing a past image of a specific object around by using the user's location information has not been studied, and there is an urgent need for a technology for providing a user's suitability as an image.

The problem to be solved by the present invention is to overcome the above problem, by using the location-based information service to combine the past image of the specific target registered in the adjacent point for each location of the user with the current image using augmented reality technology It is possible to take a picture with a combined video as a background and share it through a social network service, so that the user can place a desired place or time regardless of place or time, unlike when a user visits an existing museum or the like. It is to provide a historical information providing system and method using a location-based information service that allows you to easily check the past image and history information of multiple targets in real time on the go at a desired time.
