GeoSLAM floor plan accuracies today

Post by LPaulCook » Wed Nov 22, 2017 12:57 am

I have looked at some of the earlier posts about accuracies of the GeoSLAM product but they are all over a year old posts now.
I am a FARO x330 user for the past 2yr.11mo's, since they were first delivered. I do many types of scans but more and more to extract floor and building plans.

Can someone with current products please tell me what I might expect for "overall" and "individual room" accuracies in say a 30,000 SF floor (maybe with many rooms, hallways etc? (say in maybe a building 100'x300' overall)

Which GeoSLAM product would be best for this purpose? I know that they are much faster than the way I do them now...

L. Paul Cook, PLS

I use geoslam zeb1 and the accurancies that i checked with total station is frim 1 to 3 cm. The pain in the ass is the software (geoslam desktop) that costs 15000 $ plus vat or buying credits ( 1 credit per 2 meter cost is 0.35 euro )
If i where you i will wait paracosm px80 they sold it for 25000$ and all the data is unlocked also italian company gexcel has a same slam scanner for about 40.000 $ also data unlocked.
Geoslam has 15-20 meter range due to hokuyo head and the two others 100 meter due to velodyne head.

Hi Paul,

As mentioned above absolute accuracy across the survey should be in the region of 3cm however relative accuracy say within a room is likely to be closer to 1cm. Resulting accuracy from a SLAM based solution is always environment dependant hence best to give it a try in your typical application.

I would recommend our latest solution the ZEB-REVO RT with GeoSLAM Hub software which provides real time SLAM registration, colour point clouds, data merging, tools for automatic layout production and much more.

We have many distributors in the US so I would recommend contacting them to find out more and arrange a demo as this is the best way to see for yourself what it can do. Alternatively send me a mail and I can put you in contact with the best person.

Colour data is very interesting - my main issue with data I have seen before was the lack of colour or intensity. I'm assuming that intensity is still not a thing with the Zeb but colour can be very useful when processing data.
