Power Line Vectorization

[WigginsTech]

Hi Daniel: We are very impressed with your software and have been using it more and more for our LiDAR powerline surveys. We have donated towards your work and hope to donate more in the future as we use your software more. We were requested by our clients to provide accurate catenary curves of the power lines and we don't know how to do that besides just tracing the lines with the polyline tool which is not vey accurate and is very time consuming. So we thought that maybe you would have an idea how we could accomplish that task? If not, we were considering hiring a software developer to create a plugin for cloud compare. What are your thoughts?

Ah! That's interesting because I'm currently working on Spline support in CC. The scope is quite limited for now, but you'll be able to draw a rough polyline (picking some points along the power line with the 'Trace polyline' tool for instance) and then convert this polyline to a spline and "best-fit" it with the cloud.

My current issue is that I don't know if there's any simple format that allows to export a spline curve (maybe DXF).

By the way, if you have some sample clouds, don't hesitate to send them to me and I'll show you what can be done with this new feature.

Hi Daniel: Sorry I didn't respond to this thread sooner. I didn't receive a notification so maybe I'll have to check out my settings. Yes I would be happy to see what your new spline tool can do. Here is a link to some sample data that you can use for your experiments: https://drive.google.com/drive/folders/ ... sp=sharing

There you should find some high quality classified data including conductors.las, a full dataset in the .bin cloud compare format and a .dxf of some poles and lines created by an engineering company. I would think that .dxf or .shp would be good options for the outputs as those are the same output offered by the poly line tool in cloud compare. I think that your manual idea of picking points is a great start and would be very helpful. We would be very interested to see what you can do with it. :)

Hi,
I'm really interested in powerline classification and I tried your plugin. It's the fist time I've tried installing a plugin and I'm a little lost. I get an error.

"QCLOUDLAYERS_PLUGIN.dll does not supply meta data in the Q_PLUGIN_METADATA (see one of the example plugins)."

"I'm using CloudCompare v2.11.3 (Anoia)[64-bit]"

Are you able to help, I'm sure its a very basic solution but I'm new to CC.

Yes, I couldn't make the plugin work on my side either.

It is now part of the official 2.12.0 version!
