Point cloud model to mesh model

多一个想法和支持,心里就不会觉得绝望

Structure from motion with visualsfm

you can also find a 64-bit windows version with cuda as well as the pmvs with the code of uaxa

smart3D with the code of 7xrb

A sparse point cloud model can be generated by the visualsfm. Furthermore, a dense point cloud model can be genearted with the pmvs or cmvs program. However, these point cloud model are still less beautiful than the 3D surface model.

To this end, I will list some steps for construct the surface model with the results of the visualsfm and the dense point cloud model.

3D surface model reconstruction

File/ Open Project

choose the bundle.rd.out file first and choose the list.txt file.

File/ Import Mesh

choose the dense point cloud model .ply file

Clear the vertices with the select and delete vertices.

Filter / Point Set / Surface Reconstruction: Poisson

with the octree Depth with 10 or larger.

Filter / Selection / Select faces with edges longer than

Filters –> Selection –> Select Non-Manifold edges

delete the non-manifold edges

Filter –> Texture –> Parameterization from registered rasters

Filter –> Texture –> Project active rasters color to current mesh, filling the texture

Texture projection. Set the pixel size of the texture image, the larger the clearer.

we can set the value as 512, 1024, 2048, …

Export Mesh as…

That’s all.
