扫描电镜是研究微观结构的一种常用的科研手段,但由于荷电效应、边缘效应、样品损伤等原因,易生成低质量的电镜图像,从而影响对样品的分析。总结了低质量图像的规律,针对扫描电镜图像的特点设计了适合的增强算法,提高了图像的质量,并进一步设计了勾勒样品边缘的方法,拓展了电镜图像分析功能。基于 SoPC 技术的嵌入式平台,实现了整个电镜图像处理流程。 DEII 开发板实验表明,提出的方法可有效提高低质量电镜图片的质量,给科研工作者提供了一种更准确、轻松的从扫描电镜图像中获取所需信息的途径。
掃描電鏡是研究微觀結構的一種常用的科研手段,但由于荷電效應、邊緣效應、樣品損傷等原因,易生成低質量的電鏡圖像,從而影響對樣品的分析。總結瞭低質量圖像的規律,針對掃描電鏡圖像的特點設計瞭適閤的增彊算法,提高瞭圖像的質量,併進一步設計瞭勾勒樣品邊緣的方法,拓展瞭電鏡圖像分析功能。基于 SoPC 技術的嵌入式平檯,實現瞭整箇電鏡圖像處理流程。 DEII 開髮闆實驗錶明,提齣的方法可有效提高低質量電鏡圖片的質量,給科研工作者提供瞭一種更準確、輕鬆的從掃描電鏡圖像中穫取所需信息的途徑。

Scanning electron microscope ( SEM ) is a widely used tool on micro structure research . Because of charged effect , edge effect and sample injury , low quality SEM pictures are often got , which weaken the analysis of samples . In this paper , the reason of low quality picture and its character are studied . Based on them , a specific enhancement algorithm for low quality SEM pic-tures is designed, which increases SEM pictures′ quality. Besides that, edges of samples in picture are detected, which improves SEM′s function . The whole process is implemented in an SoPC platform . The experiments on DEII show that our method can improve SEM picture′s quality obviously . It provides researchers a novel way of extracting information from SEM picture accurately and easily .
