Automated point cloud vectorization

A new release from Pythagoras:
Some of the new features:
Automated point cloud vectorization
Classification of point cloud
Enhanced DTM performance
Updated profiling tools
General performance upgrade

There are now several software packages with the ability to vectorize of point clouds, but I've yet to see a comprehensive review of these products, comparing tools, features, price, and performance.

The classify ground looks like it did a good job, but this is possible in lots of software.

The vectorise edges from an image of road markings had a lot of extra lines created that would need clean up. Creating those manually would be quicker overall I reckon.
As for the vectorising of the building facade from point cloud data, there was even more extra lines created where no detail exists.

Unfortunately, it still looks like the cleanup time is too much in this sort of product that a well skilled CAD monkey can't beat and probably with tidier CAD practice. (not lots of unneeded nodes in the linework etc).

We've done quite a bit of work on automatic vector extraction in SCC, a couple of videos below show some of this.

Automatic kerb line extraction

Automatic rail (theoretical running edge) extraction


youtu.be/T9HPA9_aGKQ

Automatic extraction of line work based on section or selection


youtu.be/L1ApPht9Pfw


How well these techniques work in my opinion come down to the quality of data and noise removal / cleaning techniques employed. Mobile LIDAR and good quality UAV data have the added advantage of reasonably evenly spaced points which make statistical analysis of potential features easier.

+1 Nice demo. I wish all the major platforms included such tools by default: quality data > noise removal > cleaning techniques > happy clients > a cold beer!

Thanks Scott, any piece of technology that brings that cold beer closer to hand is a step forward in my book! Are you going to Geo-Business next week?

Wow, SCC looks like its handling those tasks really well. I've never seen this software before. Is there a german reseller I could contract about a trial / prices?

Hi Rob, we don't currently have a reseller in Germany but you can download a trial license here. We'll be launching SCC r13 next week at Geo Business in London which has some more automation tools, I'll post an update once it goes on general release and PM a price list.
