本文提出了一种新的方法，可以从立体图像中去除视图干扰噪声。在通过摄像机进行的室外监视中的棘手问题之一是保护玻璃表面透镜上的诸如水滴的附着噪声干扰摄像机的视野。因此，我们提出了一种方法，用于消除附着噪声从立体图像与立体相机系统。该方法以立体测量为基础，利用立体图像对之间的视差，通过比较立体图像测量的视差与立体摄像机系统与玻璃表面之间的距离来检测图像中噪声的位置。根据视差与噪声周围的视差相似的特性，可以估计出被噪声隐藏的图像区域的真实视差。最后，我们可以从图像中去除噪声，通过替换上述区域与相应的图像区域的视差参考得到的纹理。实验结果表明了该方法的有效性。
In this paper, we propose a new method that can remove view-disturbing noises from stereo images. One of the thorny problems in outdoor surveillance by a camera is that adherent noises such as waterdrops on the protecting glass surface lens disturb the view from the camera. Therefore, we propose a method for removing adherent noises from stereo images taken with a stereo camera system. Our method is based on the stereo measurement and utilizes disparities between stereo image pair, Positions of noises in images can be detected by comparing disparities measured from stereo images with the distance between the stereo camera system and the glass surface. True disparities of image regions hidden by noises can be estimated from the property that disparities are generally similar with those around noises. Finally, we can remove noises from images by replacing the above regions with textures of corresponding image regions obtained by the disparity referring. Experimental results show the effectiveness of the proposed method.
