润滑油中颗粒污染物的数字显微图像测试研究

为检测润滑油被固体机械杂质污染的程度，采用数控载物台和CCD图像捕捉技术，获取颗粒污染物试验样片的数字显微图像，对数字图像进行处理与分割，使计算机对微小颗粒具有可视化和可理解性，使用扫描标号算法测量污染颗粒的尺寸、数量与分布，经数理统计、计算机数据处理，从而确定油液污染度等级，通过数字显微图像技术的应用研究，得到一种新型、快捷、实用、经济的能对润滑油中颗粒污染物进行柔性化定量测试的方法。

Study on Microscopic Digital Image Measurement of Particles Contamination in Lubricant

To classify the level of particles contamination in lubricant,numeric controlled stage and CCD image capturing technology was used to capture microscopic digital image of the oil particles sample.The digital image was processed and segmented in order that the computer can observe and understand the particles,and the scan-mark algorithm was used to measure the sizes,amounts and distributions of particles.With the application of microscopic digital image technology,an economical,convenient and expansible oil contamination level measurement method was accomplished.
