| description | PROBLEM TO BE SOLVED: To provide a position acquisition method capable of improving precision of a position to be acquired.SOLUTION: A position acquisition method includes the steps of: selecting at least one set of N effective devices from among known devices transmitting signals to a target device and known devices receiving signals transmitted by the target device; adjusting a numerical value of a proportional coefficient for conversion for each set of N effective devices, retrieving a correction value of the proportional coefficient for conversion and causing generated N pieces of circles or spheres to have only one intersection in accordance with the correction value while defining a position of each of the effective devices as a center and defining a corrected distance between each of the effective devices and the target device as a radius, the proportional coefficient for conversion being used for converting a signal strength of a signal that the effective device transmits the target device or of a received signal transmitted by the target device into a distance; and calculating a position of the target device by using at least one correction value of the acquired conversion coefficient.SELECTED DRAWING: Figure 1
【課題】取得される位置の精度を向上させることができる位置取得方法を提供する。【解決手段】目標機器に信号を送信する既知機器及び前記目標機器により送信された信号を受信する既知機器から、少なくとも１組のＮ個の有効機器を選択する工程と、各組のＮ個の有効機器に対して、変換用比例係数の数値を調整し、前記変換用比例係数の補正値を検索し、前記補正値により、それぞれの有効機器の位置を中心として、それぞれの有効機器と前記目標機器との補正距離を半径として、生成されたＮ個の円又は球が唯一の交点を有するようにする工程であって、前記変換用比例係数は、前記有効機器が目標機器に送信した信号又は受信した前記目標機器により送信された信号の信号強度を距離に変換するために使われる、工程と、取得した前記変換係数の少なくとも一つの補正値を使用して、前記目標機器の位置を算出する工程を含む。【選択図】図１ |
