Description
y(I)=h2(I)−h1(I)=a0+a・sin(2πI/N+θ0)
(方程式1)
上式においてa0は、基準平面からの支承面の平均軸方向ずれであり、aは、正弦波の振幅であって解が求められるべき一次変数であり、Nは、正弦波の周期であり、θ0は、正弦波の初期位相である。したがって、本発明の目的は、最小二乗当て嵌め法を用いて“a”についての値を計算してこの上述の表現式が光センサ54によって提供された測定データを最適モデル化するようにすることにある。表現式(1)の線形化により、以下のように、最小二乗当て嵌め法を測定データに適用して“a”の値を求めることが容易である。
y(I)=a0+a・sin(2πI/N+θ0)
=a0+a・cosθ0・sin(2πI/N)+a・sinθ0・cos(2πI/N)
=a0+a1・sin(2πI/N)+a2・cos(2πI/N) (方程式2)
a=√(a1 2+a2 2) (方程式3)
正弦波振幅“a”がいったん知られると、容器の傾斜度を次の方程式によって計算することができる。
傾斜度=a×(容器高さ/直径) (方程式4)
計算した傾斜度が所定の大きさを超えていれば、容器は、「リーナー」と見なされ、不合格とされる。
