I’ve bought Metro Y Pro as a replacement to my structured light 3D scanners (Calibry and Calibry Mini).
My applications include, but are not limited to: people (for sculpture, medicine, theatre, FX), furniture, sculptures (20cm up to several meters large). I’m also doing a lot of mechanical parts for reverse engineering (from few centimeters up to a factory installations).
I was looking for a fast, precise device.
What I’ve recieved is a scanner that can barely make 15fps on my (very powerful) laptop.
I’ve just started my experiments, and I fully understand (I’ve been making a living from reverse engineering and 3D scanning for a 10 years now), that there’s a learning curve to each and every new device. I’m however afraid that I spend a ot of money for a device that’s unable to scan even a very simple object (I’ve tried with a chair and and failed).
I’ve included an example of my work (scale in milimeters).
EDIT: I’ve also added some photos of (extremely simple) objects, I’ve attempeted to scan. It was impossible for a scanner to capture them (no matter if I used “general” or “black object” mode).
I’ve also switched to GPU acceleration (why it doesn’t automatically apply this??), but the capture speed is still only 15fps.
I’m now seriously afraid that my device is faulty. I’ve never had such difficulty working with any scanner. I’ve used:
Artec 3D: Spider, Space Spider, Eva Lite, Eva, Leo
Thor 3D: Calibry, Calibry Mini
Rangevision: Spectrum
Ametek: Peel 3
competitor's scanner: Einscan 2, SP-V2 (they were really, really bad).
I’m also quite sure that I did my due dilligence.
The scanner is fine. 15 FPS is the maximum available in marker-less scanning mode. This mode works very poorly with parts like a chair due to its size and non-matte-coated parts. Therefore, you’ll have to apply markers and scan with a laser. It’s not a suitable choice for furniture; you’ll need the Inspair 2 for that.
Thank you! I was hoping that it will replace all my scanners, but it looks like I will need yet another one. I really don’t like working with markers. If the Metro Y Pro will not be a stellar performer in more “metrology adjacent" cases I will probably return it and go for another solution.
I also thought that it will give me a taste of what the Trackit is like. No luck in that.
MetroY is a good laser scanner. Running GPU accel for crossed, parallel, and single line you should see 50-60 fps. Because of the number of points you collect at one time in full field mode, the fps is lower. But the full field is still a blue structured light, which is why dark and shiny still struggle in that mode. The Metro series have a small FOV and only work really well on very detail rich parts in feature mode or require the use of marker dots and possibly spray for less featured items like a chair.
It sounds like you did not do quite enough research into which scanner best fits your needs. People and large objects are not what MetroY was designed for. You’d probably be better off with a Miraco which is a structured light. The MetroY laser will accel at the smaller mechanical parts for RE, but you are going to have to use markers for that. You came on here to complain, not look for help. If you want help using the scanner for its intended purpose, posting some screen shots of your settings is helpful. Posting pictures of things you failed to scan is not. With the proper setup every one of those items is scalable. Someone with 10 yrs of experience should know that…..
When I get a new tool I’m always trying understand it before I make a judgement about it’s usefulness. And believe me, I’ve only started. I certainly didn’t come here to complain. I just made an observation, with the strong notion that I’m probably wrong. One thing that all the years of doing this job taught me is humility.
I of course understand what the Metro Y Pro is and what it isn’t. What it is is a device built to a certain price point.
What I expected from it’s structured light mode is to be of ANY use at all. And now I’m trying to understand why it’s not doing what all my other 3D scanners do, or at least why it’s not doing it effectively.
I understand the framerate limitation in structured light mode. In laser mode it reaches about 58fps, even though my hardware is at least a generation older than recommended. I don’t have many issues with the software as for now. Maybe only a several seconds of freeze when changing the settings is a bit annoying.
What I have an issue with is the performance of the structured light mode. I’m used to a scanner that has a min. FoV of 86x115mm and max. 144x192mm. It gathers up to 3M points per second.
That’s why I’ve assumed that a scanner with a min. FoV of 152 × 138 mm and max of 332 × 276mm and gathering up to 7M points per second will have an easier time capturing certain geometry. It does not.
I know all the ways to make ilthe scan successful like adding extra geometry or using spray, but I assumed (perhaps incorrectly), that it’s quite weird that I’m not able to capture ANYTHING in the structured light mode (e.g. the mouse wasn’t giving me any data). In laser mode I was able to get something (and I will post my findings along with the comparison to Calibry Mini) but still it will require a scanning spray for the scan to be useful.
I will also make detailed measurements with the two scanners and compare it to their respective specifications.
Lol Oki g on the objects you want to scan they are require markers no matter what scanner you are using .
3D structured light scanner can’t scan simple geometries well that why they need markers.
MetroY Pro is great but truly not for what you need it for , Go with MIRACO Pro or better with MIRACO Plus it will allow you to better scan people and it have better tracking for objects that have less features. It is also infested scanner so you can scan objects with various colors without issue.
Trackit don’t require markers , it uses laser and can scan any object and form better than any other scanner from very small to huge size.
MetroY Pro don’t give you taste of what Trackit is , because it is totally different scanner not relaying on tracking of the objects.
Structured light scanning relays on object features or you need markers or you need to add additional geometry to support tracking using Full Field of Auto mode that use single frame shot .
Please don’t post any comparisons with other scanners because it is again the forum TOS , on top you are not familiar with scanning using Full Field so all you will do is simply comparing your skills with a scanner you don’t know exactly how to use .
Each scanner require its workflow to be followed and MetroY Pro is just perfect for what it was made.
When you use laser mode you actually don’t need any 3D spray , there are all settings that allow you to choice the proper surface , like for example the mouse can be scanned east without any markers or 3D spray , you just need to add some other parts around it for tracking or use markers around and use laser mode .
There is solution to every scanned object but it requires some knowledge , and since it is new to you learn how to use it of get much simpler scanner .
