NeRF Studio Point Cloud Question

[shunnnl]

When I open a .txt file containing coordinates and rgb values ​​after extracting a point cloud, why do the x, y, z values ​​range from -1 to 1? Is it not possible to extract the reduced coordinate values?

Are you using ns-export pointcloud for this? it should be saved as a .ply file. You can also choose whether to output points in the same coordinate frame as the input cameras, or the scaled coordinate frame internal to the NeRF

Hi, I have other question.

Why is the point cloud generated by nerfstudio not the same size as the original target size? How can I restore the point cloud to its original size?

Hi, I wonder if you're meaning total number of point clouds, or voxel size.

@tersite1 i think we want to get the same scale of point cloud on which colormap has ran or the scale to the reality .
