摘要
金相显微镜已经逐步采用数字照相技术采集、记录金相组织以及利用图像分析技术进行金相检验分析。通过分析显微镜刻度尺图像、金相样品图像,及给定特定图形且已知面积的图像,依据ISO/IEC 17025检测和校准实验室能力的通用要求,并结合金相检验标准,阐述了金相显微镜利用新方法的方法确认,其中包括量值溯源、金相组织输出、图谱比较、长度类测量和面积类测量的确认方法。这种确认的方法也作为企业显微镜改造升级和购置定量金相分析系统验收的方法。
Now digital photographing technology and image analyse technology are setted to the metallugical microscope for microstucture test and analysis. According to the ISO/IEC 17025 .:2005 and combining the standard methods of microstructure test. This paper gives several methods to validate these new methods by analyzing images of stage micrometer, metallurgical sample, and images that consisting of definite area in geometric graph, Several kinds of validation methods including of traceability of a quantity value, printing microstucture graph, comparing microstucture photo with standard photos, length meansurement, and area meansurement are discussed in this paper. These methods also can be used to check and accept quantiative image analysis system or new digital photomicrography system installed in the metallugical microscope.
