摘要
为准确描述并测量沟槽滤棒的特征参数,采用Image-Pro Plus(IPP)技术建立了一种沟槽滤棒特征参数测量系统。将5组已知沟槽面积比的沟槽滤棒标准件和10支裁切后的自制沟槽滤棒放置在显微镜载物台上,沟槽端面朝上,调整光圈亮度及显微镜焦距,按编号顺序拍摄成像,并使用IPP软件计算沟槽特征参数,运用MINITAB软件分析IPP测量系统的准确性和精密度。结果表明:1IPP测量系统操作方便,测量过程简单,能快速测量沟槽滤棒的沟槽面积比、深度、数目等特征参数。2系统对沟槽面积比、沟槽深度的测量结果不存在线性偏倚。沟槽面积比精密度指标Gage R&R=24.66%<30%,沟槽深度精密度指标Gage R&R=26.40%<30%,测量数据精密度好。3系统手动和自动两种测量模式对测量结果无显著差异(P>0.05),可以根据不同需求选择测量模式。该测量方法为研究沟槽滤棒降焦机理和提高生产过程控制能力提供了技术支持。
To describe and measure the characteristic a measuring system based on Image-Pro Plus （IPP） parameters of grooved filter rod accurately, technology was developed. Five groups of standard grooved filter rods with known groove area ratios together with ten sliced grooved filter rods were put under a microscope with their groove ends facing up. The images of the rods were taken sequentially. IPP software was adopted to calculate the characteristic parameters of the filter rods and MINTAB software to analyze the accuracy and precision of IPP measuring system. The results showed that： 1） IPP measuring system was convenient in operation with a simple measuring process and could measure the characteristic parameters （groove area ratio, groove depth, groove number） of grooved filter rods rapidly. 2） There was no linear bias in the measurements of IPP system for groove area ratio and groove depth with acceptable precision of GageR＆R 24.66% and 26.40%, respectively. 3） There was no significant difference between the measurements of IPP system under manual mode and automatic mode （P 〉0.05）. This measuring method provides technical support for studying the tar reducing mechanism of grooved filter and improving the process control in production.
