发明名称 INDOOR LOCATION SYSTEM HAVING SENSOR AND METHOD FOR CHECKING LOCATION USING THE SAME
摘要 An indoor location system having a sensor and a method for checking an indoor location using the indoor location system are disclosed. The method includes: calculating a current location coordinate by using nodes; calculating a first movement distance by comparing the current location coordinate and a stored previous location coordinate; calculating a second movement distance through a sensor; and storing the current location coordinate instead of the previous location coordinate when the distance between the first movement distance and the second movement distance is smaller than a predetermined threshold value. Accordingly, an accurate location of an object can be recognized indoors and an error can be prevented from being caused when the location of the object is recognized.
