论文摘要
我们表明，对于由内窥镜成像的平面，镜面同志是场景平面上的同心圆，图像中的嵌套椭圆形出现。我们表明，可以检测到这些椭圆，并用于估计平面的正常方向，形成正常的重建方法，我们在模拟数据上验证。实际上，内窥镜图像中可见的解剖表面是局部平面。我们使用我们的方法表明，可以针对通常在潮湿的组织上可见的众多镜面重建表面正常。我们显示了腹腔镜和结肠镜图像的结果。
We show that for a plane imaged by an endoscope the specular isophotes are concentric circles on the scene plane, which appear as nested ellipses in the image. We show that these ellipses can be detected and used to estimate the plane's normal direction, forming a normal reconstruction method, which we validate on simulated data. In practice, the anatomical surfaces visible in endoscopic images are locally planar. We use our method to show that the surface normal can thus be reconstructed for each of the numerous specularities typically visible on moist tissues. We show results on laparoscopic and colonoscopic images.
