Photogrammetric methods enable the construction of 3D SEM models from 2D images. Most software for this purpose is designed for photographic images. The software tries to minimize modelling error but some uncertainty usually remains in the model. In such approaches no ground truth measurement for microscopic objects exists for comparison with the finished model. In the proposed method, a textured model surface is compared to the SEM images to map the error locations on the model. The method is illustrated using two datasets.
摄影测量方法可从二维图像构建三维扫描电镜模型。为此目的而设计的大多数软件都用于摄影图像。该软件试图最小化建模误差，但模型中通常仍存在一些不确定性。在这种方法中，不存在用于与完成模型进行比较的微观物体的真实测量值。在所提出的方法中，将具有纹理的模型表面与 SEM 图像进行比较，以在模型上映射误差位置。该方法使用两个数据集进行说明。
