Hi All,
I was asked to do a training task to find the corrosion in the tank using a Leica geosystem scanner.
I use high resolution with .8 mm in the setting and did the scan, so can anyone please let me know why we use high resolution and what we can do with this high resolution? Because I was unable to find the depth of the corrosion in cyclone software.
Thanks!

I have no idea but you will get more replies if you include a picture of the tank or scan data.

Re: Finding measurement and depth of the CORROSION
You won't be able to acheive that kind of accuracy with a terrestrial scanner. It's a bit miss-leading that some terrestrial scanners even allow that kind of setting. With a high resolution scan+images from the scanner you could locate the area of the corrosion by +/- 5 to 6mm (depending on survey control methodology) but not the depth, unless it's very deep.shubhamr66018 wrote: ↑Tue Oct 08, 2019 6:06 pm Hi All,

You would probably need to look at a metrology scanner for that type of application.
If you don't see that there is nothing, then you are kidding yourself.

Re: Finding measurement and depth of the CORROSION
You can even get even tighter spacings than 0.8 on the P40, by setting a custom value. Useful for stuff that is very far away, and when you're in no rush to process that data, because it will clog up everything, everywhere.Matt Young wrote: ↑Wed Oct 09, 2019 7:50 amYou won't be able to acheive that kind of accuracy with a terrestrial scanner.

About rust...well, let's assume there is a lot of sediment on the bottom of the tank:
If you had a scan of the interior BEFORE there were any deposits you could calculate the volume.
Or if it is a surface tank, you could scan the interior and the exterior and derive the volume that way.
Or use a dipstick and get it done in a fraction of the time and cost

I'm sure you could set it to 0.1 of a mm of you wanted to, but you would not achieve that.You can even get even tighter spacings than 0.8 on the P40, by setting a custom value.

Re: Finding measurement and depth of the CORROSION
Scanning corrosion (or dents/damage) is best done with a portable hand scanner. Because corrosion has such an uneven, non-consistent profile using a hand scanner ensures that you get 100% coverage of the corroded area.
We use creaform HandyScan 700s for this and they work excellently and can achieve an accuracy of about 0.05 - 0.1mm.
