To realize a technology that can easily improve the accuracy of the derived stationary detection target quantity even when vibration occurs in the detection target quantity that indicates the relative positional relationship between the holding part and the transfer target location.SOLUTION: A positional relationship detection system 50 includes a measurement unit 51 that measures the positional relationship, a recording unit 52 that records the measurement data obtained by the measurement unit 51 in chronological order, and a calculation unit 53. The calculation unit 53 acquires target time series data, which is time series data of a specific detection target quantity that indicates the positional relationship, based on the measurement data recorded in the recording unit 52. The calculation unit 53 identifies a first peak and a second peak, which are two of a plurality of peaks of a target vibration, which is a vibration of the detection target quantity that appears in the target time series data. The calculation unit 53 calculates an average value of the detection target quantity included in the target time series data between the first peak and the second peak, as a stationary detection target quantity that is a detection target quantity after the target vibration has disappeared.SELECTED DRAWING: Figure 3
【課題】保持部と移載対象箇所との相対的な位置関係を示す検出対象量に振動が生じる場合であっても、導出される静止検出対象量の精度を高めやすい技術の実現が望まれる。【解決手段】位置関係検出システム50は、位置関係を計測する計測部51と、計測部51により得られた計測データを時系列で記録する記録部52と、演算部53と、を備える。演算部53は、記録部52に記録された計測データに基づいて、位置関係を示す特定の検出対象量の時系列データである対象時系列データを取得する。演算部53は、対象時系列データに表れた検出対象量の振動である対象振動の複数のピークのうちの2つである第1ピーク及び第2ピークを特定する。演算部53は、第1ピークと第2ピークとの間の対象時系列データに含まれる検出対象量の平均値を、対象振動がなくなった後の検出対象量である静止検出対象量として求める。【選択図】図3
