Hi
I am a backer for the Revopoint Trackit scanner. Very excited to get the delivery.
I am wondering if there is any plans for a hand held probe for taking single point measurements.
This would help me in my company as I would like to use it sometime as a portable CMM machine.
For quick quality checking and comparing a few points on a cad model.
Hi @Daniel_L
Not that I know of at this moment , but every Trackit unit backed on Kickstarter comes with a free one-year license (worth $499) for Revopoint Measure. It’s 3D metrology software that analyzes the shape, dimensions, and quality of objects by comparing point cloud or mesh data to CAD models or drawings.
That includes single point distance measurements that you can use to compare your results.
But as always thank you for your suggestion !
I know the software can’t replace the handheld probe in your specific needs but right now it is all it can offer.
I have also been thinking about this as an option for Trackit
Here is an example of what i presume you are thinking about
Something like this would be very useful
Hi, there is no plan till now, thanks for your suggestion, we will forward to our R&D team for consideration~
Yes, this is exactly what I was talking about.
Now we only need everyone that would like something like this to give revopoint a message here.
To show that there is a real need from the customers.
Love the idea, already a backer but this would be an awesome addition!
I am also a backer and could see where this would be useful, I used to work in the surveying industry and essentially we were collecting single points like this. If you were clever you could use this process to mark out specific points on a large object e.g. for drilling a hole with a bit of messing around
I do also think that would be a nice adition (maybe an additionnal device we could buy as an addon later).
Would be usefull to mark the depth of deep pockets / holes for example, drill positions, etc.
Plus 1 for this. It would be extremely useful
While I’m a fan of the idea, I’m thinking this is beyond scope. These probes are used to take a measurement, not input scanning data. There is a disconnect of understanding for what these probes do. Just because they have markers on them, doesn’t make them a scanning device. They are a metrology tool. Intended for measurement, not “scanning”.
Just thinking out loud;
Of what value is a single point inside of a point cloud?
Are folks advocating for this expecting Revo to incorporate Geom Design functions? When we say mark the depth or diameter, the probe is only going to provide ONE point. The scanned feature (depth or diam) is going to be a TON of points in total. Without software like RevoDesign, etc there is no way for the ONE point to become a complete diameter or floor/surface.
For these probes to have value we need:
I don’t see how single point input from a probe will provide any other value. I don’t see that sort of software development being something that will ROI for Revo. These folks are in the biz of scanners, the metrology space, not so much.
I understand where you are coming from and the scope. For me, there is a value in a single point or even just a vector. I have 3d printed some special markers before (2 spheres on a stick) to give me alignment and depth data, and yes, it takes some messing around to get that information back, but that being said, maybe my sort of work is an Edge Case. I mean, I have a medical endoscope to do internal photogrammetry of hydraulic valve bodies and oil passages in castings
e.g. the point or vector would allow me to tie my internal point cloud to the external point cloud with better accuracy. or to give depth data to a blind bolt hole so i could calculate maximum bolt length and thread engagement
actually now that i think of it with the accuracy of the trackit i can pre-scan and calibrate my two spheres and stick length and that will make my job a lot easier with thread in bosses etc to get my alignment data.
I’ve seen this used in a scanning work flow in automotive. Scanning a feature line or glass opening, door opening shapes etc. it’s nice to have the single points to define the openings or feature lines on car panels rather than try to guess a series of points on scanned data. It produces a much cleaner result and more quickly without the noise you get on mesh data.
The point would have to be “marked” in a certain way or exported in a certain format yes.
Maybe a separate file with those points in a CAD compatible software that can be then opened in QuickSurface or Geomagic.
Other brands are also providing this kind of tools (Shining 3D,…) with their “tracking” scanners and I can really see a use for this.
Most serious CAD packages will accept a .csv file
You are absolutely correct there is a use case for this. The probe is a metrology tool. Used for inspection, not scanning or RE.
That said, you are comparing an inexpensive scanner company to a WELL established legit metrology company. That’s super unfair to Revo. I seriously doubt Shining3D sees Revo as a competitor, or that Revo plans to compete in Shining’s space.
If they decided to play in the inspection space, they would need to ISO certify accuracy, repeatability, and calibration. That would expose Revo to some judgments they are currently insulated from. I don’t see it happening.
Personally, I’d rather see improvements to the existing functionality.
Guys, nothing personal against anybody but we do not going into business of other companies in our community , it is against the forum TOS. I advice to change the subject or I will close this thread. Stay on topic !
The initial premise on this thread was to use it as a portable CMM while these are metrology machines they are also a RE tool, and just about every reply on here has been in the RE space, no one here expects it to be a top end metrology device. but every one has talked about using it as a RE tool.
I gave a example of how i have used a home made version for RE and others expressed how such a device is useful to them to obtain individual points and how they use them.
So why are you trying to push as though we all want a metrology grade equipment when no one has expressed this desire?
Technically you could put a probe on the scan head as the tracker knows where it is and where it is pointed press a button, and store a point offset by the length of the probe, and you’re done you could 3d print the probe and use track it to calibrate its legth put that in your offset, hell all that would need to be done is get revo track to spit out a point coordinate and orientation value and you could use exel with the probe length to do a point transform and vola
p.s. you would need the offset from the scanners locus of orientation
pps this could be done during a pause in scanning the probed could be mounted to the scanners bottom for instance
