Description
The present invention relates to a beacon position search method and apparatus using a single terminal, and more particularly, to a beacon position search method and apparatus using a single terminal, in which a relative positional shift amount and a relative directional angle between each of three landmark points are detected by user movement to three different landmark points, And more particularly, to a beacon position search method and apparatus using a single terminal that can accurately calculate a position and a direction of a beacon through distance detection between a point and a beacon.
As is well known, efforts to solve the problem of locating objects have been made for a long time. The problem of locating such a location has become increasingly more useful in modern times. Especially, in the ubiquitous era, it is expected that it will evolve into an era where people can communicate with each other and communicate anytime and anywhere. Among the basic technologies that become the driving force of this era, the location recognition technology includes robot control, disaster, military, It will occupy an important position such that it can not find an unused field.
Conventionally, the conventional position estimation technique, which is attempted to be applied to navigation and aviation technologies, has been actively studied with a focus on the object position estimation in a computing environment along with the development of mobile computing technology in recent years. This location estimation technology is widely used in patients, robots, personnel management in hospitals, industrial sites, etc., as well as in life sciences and military operations where visibility is not secured.
Recently, various technologies have been applied to identify their own locations in portable terminals that are usually held by the general public. These mobile terminals periodically communicate with a base station in a cell in which they are located to confirm their location and receive a call service. Unlike a conventional position estimating apparatus, devices that can be used on the move, such as a portable terminal, are characterized in that their positions are not fixed. Therefore, various technical means for position estimation are needed.
Most of these position estimation techniques are techniques for estimating the position of a desired object based on an absolute reference position. In many cases, a fixed absolute reference position is an indicator.
For example, a position estimation technique using GPS is a technique for estimating a position of a mobile terminal through at least three GPS satellites whose absolute coordinates are known.
There is also a technique of estimating a position of a mobile terminal using at least three mobile communication base stations whose absolute coordinates are known, using a position estimation technique using a mobile communication base station. However, in the triangulation method using the communication base stations, the distance from 200 to 300 meters is large when the error is large.
On the other hand, there is a location estimation technique using a local communication means such as a beacon or an RFID, and a local communication means such as a beacon or an RFID, which registers a unique identification code matching a specific address in a server, Is a technology that allows a remote server to know where a corresponding mobile terminal is located.
However, this technique is also a technique for estimating a position by matching the position of a short distance communication means such as a beacon or an RFID to a unique coordinate of a specific address.
The problem is that if the exact position of the beacon is not known, it can only estimate the distance through the signal strength of the beacon in finding the beacon, but it is difficult to grasp the position because it does not know the direction.
In particular, recently, a technique of finding a valuable item through a local communication network by attaching a small beacon to a valuable item has been developed. However, since the exact beacon position can not be known even in this case, I can not help but wander around there and find the valuables.
However, in this case, there is a problem that it takes too much time to locate the object, and in the case of the store, it disturbs other customers.
In addition, there is a method for finding a beacon in addition to the above method. For example, there is a method of generating a buzzer sound to indicate a position of the beacon itself. However, this method has a problem in that there is a possibility And there were additional problems such as battery consumption of the beacon.
