摘 要  扫描电子显微镜(SEM)凭借高分辨率、大景深、快速成像等优势,广泛应用于材料学和生物学研究中的微观表征。尽管SEM图像呈现一定的立体感,其本质仍是二维图像,缺乏直接的三维信息。为实现更直观的视觉表达并精确测量样品表面特性,基于二维SEM图像的三维表面重建已成为显微视觉领域的核心课题。本文系统综述该领域近年来的研究进展,涵盖设备开发、算法优化及应用探索,重点分析单视角与多视角两种三维重建方法的特点与进展。同时,剖析当前技术瓶颈,并展望未来研究方向,以期推动该领域的进一步发展。

Abstract  The scanning electron microscope (SEM) is widely used in materials science and biology research due to its high resolution, large depth of field, and fast imaging capabilities. Although SEM images exhibit a sense of three-dimensionality, they are inherently two-dimensional and lack direct three-dimensional information. To achieve more intuitive visualization and accurate measurement of surface features, three-dimensional surface reconstruction from two-dimensional SEM images has become a key research focus in microscopic imaging. This paper presents a comprehensive review of recent advances in this field, including developments in instrumentation, algorithm optimizations, and emerging applications. Particular emphasis is placed on the feature and progress of two three-dimensional reconstruction methods: single-view and multi-view. Current technical challenges are also discussed, along with future research prospects, to support continued progress in this field.
