Gday,
we are doing a project for a hydro company and have been scanning the entire turbine runner, we can capture 80 - 90% of the blade but we have an area of data that the scanner just cant physically get into to capture data.
The idea and i am sure its been done before it to make a negative mold of the missing data, scan it, invert it and merge and align it into the rest of the data.
Has anyone done this before with turbines or other complex shapes? What material did you use?
We will have an opportunity to access the runners again in a few weeks, and i would welcome and be happy to discuss $$$'s for assistance in getting these negative models done, develop a process etc..
Location is Melbourne.
Cheers
Joel

Re: Turbine scanner missing data
Here's an idea.
Can you mark the blades with a sharpie? Put reference marks (X1) (X2) on the blades then rotate then assembly and scan the rest.
Then clean off the Sharpie with alcohol wipes.
Line up the reference marks in the computer.

Re: Turbine scanner missing data
I try to lurk quietly and stay out of other peeps business on here but Brother what you are proposing is so fraught with risk I gotta say something.
Do not blind yourself to the risk because you want to believe in your solution. All I am proposing is to truly look with a skeptic's eye and see if you still feel strongly about its efficacy.
Optical grade mirrors are your friend. Their clever application can save yer ass when no other options exist.
Best of luck

Thanks James, the diameter of the turbine is over 3m, its not something that can be marked up with a sharpie.James Hall wrote: ↑Wed May 23, 2018 6:54 pm Here's an idea.

James,
What we are essentially trying to achieve is to laser scan around a corner to a section that we can not fit the scanner into, nor will light get to or come out of. Hence the use of the mold.

Re: Turbine scanner missing data
What about using a mirror? When we scan a mirror (for example in a bathroom) you aways get a copy of the room through the mirror. Place the mirror where you can see round the corner and scan the mirror.
Of course a precise mirror would be better, and if it bends slightly or the glass is not flat it will distort the reflection, but a quick test scan will tell you if it works or not
