Zusammenfassung: | To accurately obtain a position of an operator in a system for measuring the position of the operator by radio waves.SOLUTION: A moving object information analysis device is a device for measuring a position of a moving object based on measurement information by radio waves relative to the moving object, wherein a position information table for holding information on a measured time and a position of a measuring point and a table for holding information on a grid point arranged in an area for measuring the moving object are held for each moving object, and the position of the measuring point is replaced with a position of the grid point in the vicinity thereof and stored. In addition, the moving object information analysis device performs overlapping point removing processing for aggregating a plurality of overlapping measuring points and removing the overlapping points as noise, dynamic line vibration removing processing for removing the dynamic line vibration as noise when a moving locus reciprocates or circulates in a short time, and speed check determination processing for removing a measuring point at a moving destination as noise when a moving speed is high.SELECTED DRAWING: Figure 10
【課題】電波により作業者の位置を測位するシステムおいて、作業者の位置を精度よく求める。【解決手段】移動体情報解析装置は、移動体に対する電波による測定情報により、移動体の位置を測定する装置であって、移動体ごとに、測定した時刻と測定点の位置の情報を保持する位置情報テーブルと、移動体の測定する領域に配置されるグリッド点の情報を保持するテーブルとを保持し、測定点の位置をその近傍にあるグリッド点の位置に置き換えて記憶する。また、複数の重複した測定点を集約して、ノイズとして除去する重複点除去処理、移動軌跡が短時間内に往復・周回しているときに、ノイズとして除去する動線振動除去処理、移動速度が大きいときに移動先の測定点をノイズとして除去する速度チェック判定処理を行う。【選択図】 図10 |
