Is it possible to export a point cloud from pix4d into a 3rd party editing software to clean up the point cloud and then import it back into pix4d after the clean up in order to generate a 3D mesh?
Edit point cloud in Pix4d, moving unwanted points into ‘deleted’ group
These deleted points will not be taken into consideration when mesh is processed
Currently, you can not generate the 3D Textured Mesh based on a Point Cloud that was edited in a 3rd party software and was imported again into Pix4Dmapper. I have added this idea to our Suggestion list. Our Product Development Team will consider it for future version of the software.
As Cathal mentioned, you could edit the Point CLoud into Pix4Ddesktop:
Save the project and generate the 3D Textured Mesh:
The Deleted points will not be taken into account for the generation of the 3D Textured Mesh.
Unfortunately after two years this is still not possible. I think it would be a very small project for Pix4D with a great impact.
The possibilities for editing the point cloud in Pix4Dmapper is really not sufficient.
Indeed, this option is not available at the moment in Pix4Dmapper. However, you can export the point cloud into the free software CloudCompare, clean up the point cloud and build the mesh as follows:
- Open the point cloud by clicking the tab File > Open .
- While clicking on the point cloud in the DB Tree , select tab Edit > Normals > Compute >adjust the parameters according to your preference.
- Click on tab Plugins > PoissonRecon > adjust Octree Depth (the larger the number, the more details - we recommend starting with a value of 9).
