讨论了利用全方位摄像机和投影仪进行环境深度测量的方法。在本文中，我们使用两个全向摄像机拍摄图案的图像，并估计从相机到物体的立体方法的距离。作为投影模式，我们采用相移法来区分摄像机之间的对应点，因为这种方法可以获得高分辨率的对应点。本文还讨论了由全向摄像机特性引起的对应点坐标的校正方法。实验结果表明，该方法可以有效地测量三维深度。
We discuss surrounding depth measurement method using omni-directional cameras and projectors. In this paper, we use two omni-directional cameras to take images of patterns, and estimate distances from cameras to objects by the stereo method. As the pattern for projection to distiguish corresponding points between cameras, we employ the phase shifting method, because this method can obtain corresponding points with high resolution. We also discuss methods to correct coordinates of corresponding points caused by properties of omni-directional cameras. As results of experiments, we can show effectiveness of proposed method by measuring 3D depth.
