Re: [Qgis-user] First steps with 3D Scan Data?
Hi Bernd: Just a clarification on LAStools. The library has open as well as licensed algorithms. Typically, the basic functionality is available for free and implemented in QGIS. The advanced tools are available through licensing. Rapidlasso GmbH also developed the laz format which is an efficient compression standard to make large datasets/point clouds more manageable. PDAL and R can be used to process the data but if your data is compressed, you would have to use the unlicensed Laszip routine available in QGIS 3.x to convert the data to an uncompressed las format.

Re: [Qgis-user] First steps with 3D Scan Data?
Hi Bernd.It sounds like the data were acquired and processed with Trimble hardware and software. I am not familiar with their products however they tend to write proprietary files unless they are exported to a open data format within the Trimble Procesding software. I will have a look at ghd standards when I have a few moments. As the data are kased scans, Agrisofglt or Pix4d software are not suitable as these aed I are based, structure from motion solutions.Kirk SchmidtSent from my Galaxy Original message From: Bernd Vogelgesang Date: 2021-03-26 7:34 a.m. (GMT-04:00) To: Richard McDonnell , info , qgis-user Subject: Re: [Qgis-user] First steps with 3D Scan Data?

Hi, Those are propriatary file format made to be use with Trimble products such as Trimble Business Center or Realworks, there is nothing you can but ask someone having one of these softwares to convert it to E57 (if you want the pictures) or LAS/LAZ (point cloud only). There is nothing that QGIS or the underlying library (PDAL) can do with such a closed dataset. regards JRM Le vendredi 26 mars 2021 à 09:01 +0100, Bernd Vogelgesang a écrit : > Hi Benoit, > > as I was not present when the scans were made, I can only assume that > this was a laser scanner on a tripod. > > With the sent data, there is a Trimble Scan Explorer Viewer software > where I can make a "virtual walk" through the scene, so there have to > be > photos but also laser scan data as I can see from different view > modes. > > As I said, this is the very first time I get in touch with this > stuff, > and Google was of no big help so far. > > Besides of tons of other files, the bigger ones with around 50 to 80 > MB > are .rwcx and .tzf files. > I hoped that someone would know what these file explicitly hold, and > what I have to do to get them e.g. into QGIS or other open source > software. > > Cheers, > > Bernd > > On 26.03.21 08:40, info wrote: > > Hi Bernd, > > > > Well, could you give more info?

Re: [Qgis-user] First steps with 3D Scan Data?
Hi, If you are looking for an Opensource Pointcloud Stack, have a look at this video on youtube by Klas Karlsson https://www.youtube.com/watch?v=pe04m-gHM-M=1180s To make the above work for you , you would have needed to receive the scan data in LAS format, it would appear that the rcwx files are proprietary format from Trimble, and are Trimble RealWorks Project files. The Pointcloud data is in the .tzf files Can you ask the provider of the data to export the scan data as a LAS Format File? You should then be able absorb the data into an Open Source Stack i.e.Cloud Compare and QGIS 3.18 Hope that’s of some guidance and help.

Re: [Qgis-user] First steps with 3D Scan Data?
You should make a try with the 3d live scanner Android app by Lubos Vonasek. It offers live photogrammetry with a simple smartphone (better with a tof sensor). I'm looking too for easy solutions to use scans with QGIS.

Definitely try the Agisoft solution, it is great. We use for recording

Re: [Qgis-user] First steps with 3D Scan Data?
I know nothing of the data you have or the subject in general, but was
intrigued a few years ago with software that would generate 3d models
from photos ("scans from all angles"?). Look at
https://www.agisoft.com/features/standard-edition/ for example. May not
be helpful or fruitful, but fun (and pretty incredible).
Good Luck,
David

Hi folks,
in a project on a former dumpside now to be transformed into a sand
lizard habitat, I saw the chance to get my hands dirty for the first
time on 3D scan data (terrestrial). I received 10GB of stuff, and now
I'm completely lost.
The data consists of .rwcx files, .tzf files and lots of other stuff.
Is there any chance that I can process any of this data with an open
source stack?
Or what should be done, to make them digestible?
Second step: There seem to be 32 different scans of the area form all
angles. In case I succeed to somehow load the data, how do I combine
them ?
For the first steps, I actually "only" would like to generate a decent
DEM from the data to be able to place some features on a map for the
guys in charge to do the habitat stuff.
Any kind of hints or links to reads about this topic would be appreciated
Cheers,

[Qgis-user] First steps with 3D Scan Data?
Hi folks, in a project on a former dumpside now to be transformed into a sand lizard habitat, I saw the chance to get my hands dirty for the first time on 3D scan data (terrestrial). I received 10GB of stuff, and now I'm completely lost. The data consists of .rwcx files, .tzf files and lots of other stuff. Is there any chance that I can process any of this data with an open source stack? Or what should be done, to make them digestible? Second step: There seem to be 32 different scans of the area form all angles. In case I succeed to somehow load the data, how do I combine them ? For the first steps, I actually "only" would like to generate a decent DEM from the data to be able to place some features on a map for the guys in charge to do the habitat stuff.
