Re: NavVis VLX - wearable mapping

Post by yankoch »

Hello Georg,

I certainly didn't intend to criticize the VLX: your team did a great job, and there is a world between the VLX and what I saw some years ago with the Zeb Revo.
But as I'm involved in industrial piping & process, I have a tendency to zoom in when I get scans.
As I said, the VLX is perfect for classical BIM. I also offers a smoother rendering of colors.
With terrestrial laser scanners, we are closer to a building metrology : flatness, beam bending, pipes / flanges modeling...
This requires a good scanner and very good practices.
In my example above, the height map of the TLS could have been improved by unlocking the inclinometer on some scanning positions, because it often introduces a small mismatch. This is why we see some red stipes on yellow areas.

Thanks Yan, all good and your feedback is much appreciated! That how we learn and make further progress. Forgive me when I come over a bit defensive sometimes.. I guess that's because the VLX feels to me and the people at NavVis as more than just a product ;)

Hey guys,
i recently teamed up with one of our partners in germany to validate the speed and quality of data capturing with Navvis M6 and VLX. The results you can see below in the video. I am curios on your thoughts on the result.

Btw: for better look inside i cutted some outer walls ;)

Is this a new product (side development) from NavVis? ;) Let's hope not!

Omg, haha, I first thought that's a photoshop ;)
Seems the virus has more side effects than we all thought ;)


But check out this amazing unboxing video for the VLX. Of course I am biased, but probably the best unboxing video I have ever seen :)

Nice video and point cloud looks good. Couple of questions, what was the main tool for capture, M6 or VLX?

Also, how did you capture the clock tower with the narrow staircase etc?

Hi Stuart,
thank you asking for further details. The large floor areas were captured with the M6. The staircases and the top floor with smaller rooms were captured with the VLX. This was very efficient to quickly capture all areas in parallel at the same time.

Yes, the clock tower was bit more tricky as the whole roof had a lot of tiny spaces and narrow areas. No issue for the laserscanner and the SLAM. Just to make proper pics i had to bend down sometimes. In the tower itself and the narrow staircase I was walking bit slower and make sure to move the scanner in all relevant corners. The live map on the display was very helpful to see the coverage and the remaining areas. I think the continuous mobile mapping approach is more efficient for such structured environment to cover all hidden and shadowing spaces instead of discrete measurements with classic laserscanner. What do you think?

Excellent, thank you for getting back to me. It is impressive you managed to get those upper areas in the clock tower with just the VLX, interesting bit of kit.

On January 26th we will host a webinar with our Head of Mapping & Perception and our Program Manager for Mobile Mapping Solutions.
Both will give you a deep insight into the software background of VLX & M6 and you can ask all the questions and suggestions around SLAM, data fusion, and more.

Maybe most importantly they will show you the results of our upcoming new software release which will further increase accuracy by another 25%.
Check it out to see what this mean for your projects
