Unstructured Lidar scans

[ejohn3d]

I am working with ptx files, that are already lined up, that I just want to merge and be able generate a mesh from. The problem I am having is that the point clouds are unstructured in 3df zephyr pro (trial), and I can not seem to figure out how to be able to structure them. I have gone through the tutorials for control point and fine point reconstruction, but they seem to be using a structured cloud to structure the unstructured one. I also have just been playing around with some of the registration tools, but make structured is always greyed out.
Is there any way that I can structure several unstructured dense point clouds without a structured reference? or can I generate a mesh from an unstructured cloud?

Hi Ejohn3D,

the 'make structured' option is enabled when:
- The center of the scan is in the scan file (should be your case)
- The bubble view images/information are in the scan file (not your case as ptx does not contain bubble view information)
- Some photos are alraedy in the workspace, coming for example from photogrammetry (not your case)

To further investigate the problem you are having with the tx files, I would need to check one of them. Can you please send me a scan file to support@3dflow.net? As an additional test you can try to convert the scan to e57 and try again loading them in Zephyr. Thanks
