<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">高度测量,是基于光栅数据能正常采集的情况下进行的。</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">轮毂高度计算公式:</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">高度=光栅遮挡数*光栅倍率+基准高度</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">光栅遮挡数:是有物品挡住光栅时,光栅采样返回的数据</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">光栅倍率:是光栅自身的精度,每一格光栅所代表的高度是多少</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">基准高度:是在光栅无法照射的地方的高度大小,需要用直尺直接测量光栅底部与流水线的最低平面的距离</p></body></html>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">曲率=轮毂高度*k+B 计算曲率的前提是轮毂的高度数据必须准确(误差小)</p></body></html>
