This documentation describes an addon for Blender that allows to import different reconstruction results of several
Structure from Motion and
Multi-View Stereo libraries.
Supported libraries (data formats):
In addition, the addon supports some common point cloud data formats:
pillowto read image sizes from disk. 2 Requires
pillowfor point color computation.
pyntcloudfor parsing. 4 Requires
pylasfor parsing. 5 Requires
Compatible with Blender 2.8.0 onwards. There is an older version of the addon available for Blender 2.79 that allows to import NVM files - see the 2.79 branch.

import the results into Blender
Example Results (Shipped with Addon)¶
This repository contains an example Colmap model. The following image shows the imported camera poses, image planes and point cloud in Blender’s 3D view.
The input images of the Colmap model are located here: https://github.com/openMVG/ImageDataset_SceauxCastle.
The addon computes an animated camera with corresponding background images from the reconstructed camera poses.
There is also an import option that allows to interpolate the reconstructed camera poses.
In addition, the addon allows to import meshes contained in the workspaces of specific libraries. Manually imported meshes can also be aligned with the corresponding reconstruction by following the instructions here.
The addon offers an option to draw big point clouds with OpenGL to reduce computational requirements. The addon provides a panel to export these OpenGL point clouds renderings - see Point Cloud Visualization and Rendering.
