Title:
画像から奥行きマップを決定する方法、奥行きマップを決定する装置
Document Type and Number:
Japanese Patent JP5249221
Kind Code:
B2
Abstract:
Window based matching is used to determine a depth map from images obtained from different orientations. A set of matching windows is used for points of the image for which the depth is to be determined. A provisional depth map is generated wherein to each point more than one candidate disparity value is attributed. The provisional depth map is filtered by a surface filtering wherein at least the z-component of a norm of a sum of unit vectors pointing from the candidate disparity values for neighboring points to a point of interest.
