Patent Searching and Data


Title:
三次元再構築方法、装置、機器及び記憶媒体
Document Type and Number:
Japanese Patent JP7352748
Kind Code:
B2
Abstract:
A method for reconstructing three-dimensional includes the following operations. At least two frames of first key images for current reconstruction are acquired. A first space surrounding visual cones of the at least two frames of the first key images is determined. The first key images are obtained by photographing a to-be-reconstructed target. A first feature map of the first space is determined based on image information in the several frames of the first key images. The first feature map includes first feature information of voxels in the first space. A first reconstruction result of the current reconstruction is obtained based on the first feature map. A second reconstruction result obtained by previous reconstruction is updated based on the first reconstruction result of the current reconstruction.
