Largest Scan Project

Post by boxel0 »

Hi Guys,

We have, what we would class as, a pretty big scan job coming up, which at the moment we estimate roughly 2500 scans.

Has anyone else accomplished and registered a project this big within FARO Scene?

Cheers Lewis

It should be able to handled it as that's the norm these days. Although, I've not used it in years so I'll let others answer this one.

Hi Lewis

we have completed projects of this size on many occasions.

The largest single project was nearly 3000 scans however this does take quite a while to save and work on.

We are currently working on a large building in London which will be over 3000 scans but we are breaking this down into individual projects based upon groups of floors to make the saving of the project quicker (also the writing of websharecloud)

If you cluster correctly and keep things ordered then the limitations of the project size is really down to processing power.

Hi Lewis

We've done a fair few projects of this size. As Simon rightly says, you'll need to split it up into smaller manageable sized projects otherwise you'll run into all sorts of time related issues with SCENE. Maybe try and keep each project down to around 600 scans. Your key to success will be good survey control, and lots of it! Traverse every floor and survey in lots of checkerboards on each one. When it comes to registration our advice would be to keep your cluster sizes down to below 100 scans and, unless it's absolutely essential, to avoid using cloud to cloud at all - targeted registration is so much quicker in the office. Trying to do something like this cloud to cloud in SCENE will cost you weeks of extra time and much frustration. My final comment would be to forget creating scan point clouds - again, this will cost you so much time that you'll live to regret it... deeply!

I could now have a rant about how I think working on anything other than projects consisting of a moderate number of scans shows how Faro have negligently failed to invest sufficiently in SCENE, despite bringing in millions of dollars in users' maintenance payments each year; how I think it's no longer fit for purpose and should be scrapped; and that Faro should invest in writing something new from scratch that doesn't have all the ridiculous time-consuming fiddles and workarounds in it that cost my business vast amounts of money each year. But I'll leave that to another day!

If you're interested, I wrote a blog about a similar sized project we completed last year. You can read it here:

Good luck with the project!

Thanks guys, all really great responses, we do alot of projects which are 500 plus; but this next step up worried me

Whilst on site, we try to manage areas by renaming scan files logically, so once back in the office we can break the scans down into logical clusters.

I agree that there needs improvement of faro scene software,

Thanks again

I'm glad I'm not the only one that see the delays...
Coming from a zf 5010x and its processing. The Faro has been less than desirable, I'm glad for these forums, guys have all given me ideas to adapt my current workflows to this.

All I can say is watch this space 😂

As a downstream user of large surveys, it sounds great getting one single surveys of thousands of scans, people love impressing everyone with the statistics. All that happens though is that you delivery a thumping great blob and the user is left looking for a needle in a hay stack trying to find room 25 on the 15 floor. If the data were supplied in logical units it would make everyone's life more efficient.

The number of points in the surveys is not really an issue these days for Plant design systems, and we are happy to develop tools to classify regions of data, but if we worked together users of surveys would be even more efficient.

I agree with the others, I have a 5 story building that we broke down into floors and then areas because my $8000 way upgraded computer was great at it but the engineers and maintenance managers computers standard govt issued machines $1200 max price could not handle any more than 30-50 scans at a time or would be crawling at a standstill..

We ended up doing each floor as North Hallway, South Hallway, then North Units and South Units, which ended up being A Unit, B Unit, C Unit, D Unit, E Unit, F Unit all are jail cells.. then we did the above the ceiling so we modified the hallways to be below ceiling and above.. the best so far is to stay in the 30-50 range max but for standard computers running a free version of Recap it performs much better with limiting to about 15-20 per grouping that way every employee on any computer can see it without all the lag..

If I get over 100 scans its gets a little tricky selecting the scan sphere that I want so I end up going into AutoCAD and making different layers for diff elevations of scans then I can isolate that way. You could probably push your system further but its going to drive you nuts when you want to see that one place that is somewhere in the 3000 scans.
