Global registration fails on my data #471
Comments
It is because the point clouds are too tiny. The tutorial code is intended for the space using metric unit: 1 means 1m. However, the horizontal/vertical span of your point cloud is about 0.00035. If you directly reuse the tutorial code, this means you are using point clouds spanning only 0.035mm. In this case, since the tutorial code downsamples point using voxels of few centimeters size, all the points are being inside to a single voxel. As a result, only a single point will remain after downsampling. That's why you observed nothing (actually there should be a single point after downsampling) In summary, you can try one of the following things:

Perfect, thanks for your response. I'll try your suggestions. |
Can verify that the white blank screen gets fixed by adjusting |
When I run global registration python script on my point clouds, I only get a blank white viewer with no data visualized.
What could be the reason for this failure? I am attaching my point cloud data, could someone please take a look.
Thanks in advance.
