Looking through some open source code libraries, such as open3d, I found that the key to this algorithm is to find the right radius of the sphere. Unlike previous methods that estimate single-view depth maps separately on each key-frame and fuse them later, we propose to directly reconstruct local surfaces represented as sparse TSDF volumes for each video fragment sequentially by a neural network. m Matlab file.
