本文提出了一种基于从多个位置观看时对象的深度信息生成从虚拟视点拍摄的图像的方法。首先，将来自视点的深度图转换为从虚拟点观看的对象的深度图。然后，基于另一视点的深度图，补充虚拟视点深度图的遮挡区域并校正深度值。通过深度值插值和平滑来适当使用真实图像，生成虚拟视点图像。应用所提出的方法使得生成遮挡较少的虚拟视点图像成为可能，即使对于偏离实际相机位置很大的视点也是如此。 © 2004 Wiley periodicals, Inc.

This paper proposes a method of generation of images taken from a virtual viewpoint, based on depth information on the object when viewed from multiple positions. First, the depth map from a viewpoint is converted to the depth map of the object as viewed from a virtual point. Then, based on the depth map from another viewpoint, the occlusion area of the virtual viewpoint depth map is complemented and the depth value is corrected. By appropriate use of real images through interpolation of depth values and smoothing, a virtual viewpoint image is generated. Applying the proposed method makes it possible to generate a virtual viewpoint image with less occlusion, even for a viewpoint deviating greatly from the actual camera position. © 2004 Wiley Periodicals, Inc.
