cannot export e57 to las file

[diudiu]

Hi guys,

i'm working on a point cloud data. The workflow i hope to realize is basically like this: Recap --> E57 file --> CloudCompare --> las file
The data was originally processed in Recap. In order to convert it into a LAS file, i exported it as an E57 file in Recap and then import the E57 file into CloudCopmpare. But now i cannot export it as LAS file. The export options dont include las file formate.

The point cloud data need no more editing. Does anybody knows why, or how can i export it into las file? Thanks in advance!

Which version are you using?

LAS should be supported at least on Windows and macOS for most of the recent versions...

Dont know if your question is still valid but I had the same problem just now...and i found your post...and than I found an answer (at least for me)

When you open a e57 in CloudCompare you see in the DB Tree a structure like this:

Folder Pointcloud.e57 (c:/...)
.......Folder "File Structure"
.......Scan 001
.......Scan 002
.......Scab 003
...and so on

So when you select the Folder (Pointcloud.e57) and click save you only have a few export option. But when you click on a scan you have much more options to choose (including LAS).

So I merged all the Scans and then it worked fine...maybe it helps you as well (or someone else who stumble upon this post in the future)
