通過工廠標定和動態后部署補償提高傳感器測量精度

　　就在不久前，工廠傳感器校準和自我校準傳感器要么不存在，要么稀有。產品開發的進步改變了這一切，在傳感器成本，準確性，可靠性，當然，易用性等領域的設計師帶來了福音。

　　許多單獨的傳感器現在校準之前或之后部署。預部署校準的一個優點是，制造商可以校準多個傳感器在同一時間，而不是單獨，從而節省了大量的成本。在就地校準，另一方面，發生在傳感器被安裝后，是更費時的，并且傳感器可能暴露于環境因素，可能會影響校準精度。

　　n the past， calibration efforts were frankly a nightmare for the designer. Challenges did not stop after the first calibration， as there were many obstacles to keeping sensors accurate. Either pre- or self-calibration provides：

　　Elimination of measuring uncertainty

　　Reliability of data over time

　　Elimination or a significant impact on frequency of maintenance

　　Minimal interference with sensor function

　　Cost reduction

　　Especially in the case of sensor fusion， whereby each sensor in the environment has different error characteristics， calibration as each sensor is added makes sense.
