基于超景深三维可视化方案的材料表面显微形貌分析与表征

Analysis and Characterization on Material Surface Micro Morphology Based on Large Scene Depth and 3D Visualization

基于具备超景深连续变倍功能的体视显微镜,对材料表面显微形貌在z轴方向逐层采集图像,通过将采集的图像堆叠生成高度图从而在三维中实现材料表面显微形貌的可视化。结果表明:在表征高孔隙率材料表面状况及分析材料表面腐蚀磨损状况等情况下,三维可视化图像较二维平面形貌图像更为直观准确;超景深三维可视化作为一种有别于采集二维平面形貌的表征方法,可为分析材料表面显微形貌提供更多的信息。

Based on a stereo microscope with large scene depth continuous zoom function,the surface micro morphology images of the material were collected layer by layer in the z-axis direction,and the height map was generated by stacking the acquired images to realize the visualization of the material surface micro morphology in three dimensions (3D).The results show that the three-dimensional visualization image is more intuitive and accurate than the two-dimensional planar image in characterizing the surface condition of high porosity materials and analyzing the surface corrosion and wear condition of materials.The large scene depth and 3D visualization is a characterization method which is different from collecting the two-dimensional planar morphology and can provide more information for analyzing the surface micro morphology of materials.
