这项工作研究了光学相干断层扫描和两个相机的组合，观察微观场景。立体视觉提供逼真的图像，但穿透深度有限。光学相干断层扫描 (OCT) 可以观察皮下结构，但 3D-OCT 体积数据无法为外科医生提供熟悉的视图。立体相机设置与 OCT 成像的扩展结合了两种模式的优点。为了让外科医生能够方便地将 OCT 集成到视觉界面中，我们提出了 OCT 和立体相机数据的自动图像处理分析以及增强现实可视化的组合成像。因此，我们关心 OCT 图像噪声、执行分割以及开发适当的配准对象和方法。立体相机和 OCT 之间的配准导致五次测量的平均值为 284 μm 的均方根误差。所提出的方法是两种成像模式融合的基础。增强现实显示为结果的应用。进一步的发展导致皮下结构的融合可视化（作为 OCT 图像的信息）进入立体视觉。
This work investigates combination of Optical Coherence Tomography and two cameras, observing a microscopic scene. Stereo vision provides realistic images, but is limited in terms of penetration depth. Optical Coherence Tomography (OCT) enables access to subcutaneous structures, but 3D-OCT volume data do not give the surgeon a familiar view. The extension of the stereo camera setup with OCT imaging combines the benefits of both modalities. In order to provide the surgeon with a convenient integration of OCT into the vision interface, we present an automated image processing analysis of OCT and stereo camera data as well as combined imaging as augmented reality visualization. Therefore, we care about OCT image noise, perform segmentation as well as develop proper registration objects and methods. The registration between stereo camera and OCT results in a Root Mean Square error of 284 μm as average of five measurements. The presented methods are fundamental for fusion of both imaging modalities. Augmented reality is shown as application of the results. Further developments lead to fused visualization of subcutaneous structures, as information of OCT images, into stereo vision.
