　　通过工厂标定和动态后部署补偿提高传感器测量精度

　　就在不久前，工厂传感器校准和自我校准传感器要么不存在，要么稀有。产品开发的进步改变了这一切，在传感器成本，准确性，可靠性，当然，易用性等领域的设计师带来了福音。

　　许多单独的传感器现在校准之前或之后部署。预部署校准的一个优点是，制造商可以校准多个传感器在同一时间，而不是单独，从而节省了大量的成本。在就地校准，另一方面，发生在传感器被安装后，是更费时的，并且传感器可能暴露于环境因素，可能会影响校准精度。

　　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.
