摘　　要：维氏硬度测量法是一种常用的测量材料硬度的方法。对于传统的人工测量方法,不仅劳动强度大,并且测量过程较易受材料表面维氏压痕图像的成形影响,难以保证测量精度。相比之下,采用图像处理技术实现维氏硬度自动测量可以大幅降低劳动强度,同时对复杂测量环境具有较强的鲁棒性。维氏压痕图像的成像、图片预处理和压痕面积的获取是视觉测量的关键环节。本文介绍了相关内容的主要研究进展,分析了现有方法的特点与不足,最后讨论了维氏硬度自动测量技术领域研究的发展趋势。The Vickers hardness measurement method is one of the most commonly used methods of measuring the hardness of materials.Traditional manual measurement is not only labor-intensive but also influenced by the material surface,making it difficult to guarantee measurement accuracy.In contrast,automatic Vickers hardness measurement using image processing technology can significantly reduce labor intensity and is highly robust in complex measurement environments.The imaging,pre-processing,and acquisition of the indentation vertex position of the Vickers indentation image are key aspects of visual measurement.This paper presents the main research advances in the relevant content and analyses the characteristics and shortcomings of existing methods.It also discusses the development trends of research in this technical field.
