Does, anyone have any X7 sample data from a measured building survey they could share?

Thanks in advance.... ;)

There you have a sample in RCP: https://www.dropbox.com/s/fod3uya7qyfxk ... 7.rar?dl=0

If the link is not working anymore or if you want the sample in another format, just tell me.

The sample is the scanning of a big residential building in San Sebastian, Spain, and then I would create a BIM model. I made it to test the Trimble X7 with a local seller, so that's why I've used different resolutions and coloured/grey scannings.

The registration was directly made with the Perspective software, excepting the scan nº 8. It was a scanning made from far away and I had to register it in office using Realworks.

My review about the scanner:
- Good speed/resolution balance.
- Good price (40k€ tax not included aprox., X7 + Perspective)
- Good weight.
- Regular finishing materials (plastic). Not too robust, but is ok.
- Bad measurement quality. Ok for clear and close surfaces. Bad for dark and far surfaces.
- Good interface of Perspective software.
- Good registration in Perspective. Cloud-to-cloud, you can only register scannings by pairs.
- Good size of files.

It's a shame because I really liked this scanner and it could have saved me a lot of hours registering projects in office. However pointclouds are too noisy for me as I works usually in this kind of big buildings.

Agur,

Martin Osa

Data doesn't look too bad to me. This looks like a scanner for these kind of environements. Max distance 50m and forget the rest.

9 scans should register without a breeze.

I really would like to see it scanning an complex indoor office building and going through stairs.

It has its purposes for sure : small sites, construction sites with lots of elements,... Nothing to do like a 3000 scan project with imho.

i use the X7 scanner on all of our projects now. I am in the Oil and Gas industry and I scan everything from buildings and small skids to entire plants. I havent had any issues with with this system other than long distance jumps in my setups but those are just poor target placement on my part :shock:

I have had some of the designers in the office complain about the graininess of some of the scans after being brought into recap (still way better than other companies scans we used to get data from), but today i am testing out a longer method of getting my scan into Recap with more points. I will be going from realworks to e57, then put the e57 into recap with the normal point decimation being 5mm coming from realworks automatically, I will be reducing that down to 1mm when i manualy import from the E57 files. We will see how detailed i can get it.
