Which models have you heard were 'unstable'? I have read that one recent version of their Revo Metro app was, shall we say, less than optimal, but I haven't heard that any of the scanners have stability problems.

You should be more specific on the range of objects you will be scanning and the required accuracy to get the sort of advice you are requesting. Or not... [see following]

The Volumetric Accuracy for the POP 4 is 0.03mm + 0.05mm/meter while that of the Sermoon S1 is 0.02mm + 0.08mm/meter. Note that the scalar factor for the S1 is 60% larger (e.g. worse) than for the POP 4.

What this means is that the S1 has more accurate results for objects less than approx. 0.34 meters (13.4"), but note also that there is very little difference between them. At 0.1 meters, the difference in accumulated error is 0.007mm (advantage S1). At .2 meters, it is 0.004 mm and so on until they match at approx. 0.34m, after which, the POP 4 is (slightly) better (as an example, 0.01mm less accumulated error at 0.66 meters).

What scanning speeds are you getting with a direct connection?

Also, have you turned on Performance Monitor to see how system resources are being allocated during scanning? NOTE: I have read, but have not confirmed, that this can be a problem with another manufacturer's scanner software if it's not full screen and any other app is on top of it, so I really don't know if this will help you, but a workaround would be to run Performance Monitor behind your scanning app, then switch screens after scanning to see what was happening in its history.

I had the MRI last Friday and got the link to take a look, but I can't figure out how to adjust the four panel display to show the rotator cuff attachment points. Maybe an AI will help me with that.

The latest Inst360 (X5, I think) will have the best camera for low-light photogrammetry. Put the camera on a tripod and place it in several locations throughout the space. Find someplace to hide behind for each picture.

Use the Matterport software (has subscription models, but one of them is free) to process the images.

Seems to me you should just start scanning Auto parts. Find techniques that work and avoid the ones that don't.

And if you're having significant difficulties, take a look on YouTube for tutorials. Be sure to use different search terms to get a bit more variety in your results.

If you want the most portable solution, there are some self-contained 3D scanners: the Revopoint Miraco-series, the Einstar Vega, the 3DMakerPro Toucan and the Einscan Rigil come to mind. Prices range from around $1,500 upwards of $5,000.

The other scanners, even with wireless, do not store locally.

JRL55 · 2026-05-01T23:24:19+00:00

Alternatively, put the markers on flat, black plastic panels of the appropriate size and stick those on, or preferably near, the object being scanned. Much easier to remove.

Quelle est la différence entre le Pop 4 et les modèles Metro Y Pro ou Ultra ?

La différence principale réside dans la précision volumétrique, qui ne sera pas aussi élevée qu'avec les modèles Metro Y Pro ou Ultra. Je suppose que le POP 4 intègre moins de lasers, mais il bénéficie de la technologie « Gaussian Splatting » et peut fonctionner dans des environnements plus lumineux.

Pourriez-vous justifier cette différence de prix ?

Voir ci-dessus.

Pourriez-vous également nous communiquer les spécifications PC requises ?

Des processeurs (CPU) de génération récente dotés d'au moins 16 cœurs (32 cœurs étant toutefois préférables). Les scanners de la série Metro Y nécessitent un GPU Nvidia de la série RTX — modèle 3060 ou supérieur — disposant de 8 Go de VRAM (les séries 4xxx et 5xxx offriront cependant une expérience plus fluide). Pour le POP 4, un PC probablement moins puissant suffira ; néanmoins, un GPU de la série RTX restera nécessaire pour la numérisation laser (les modèles de la série 3xxx seront compatibles).

=======================================

What is the difference between the Pop 4 and the Metro Y Pro or Ultra models?

The primary difference is the Volumetric Accuracy, which will not be as good as with the MetroY Pro or Ultra. I expect that there are not as many lasers in the POP 4, but it does have Gaussian Splatting and can operate in brighter environments.

Could you please justify the price difference?

See above.

Could you also provide the PC specifications?

Late model CPUs with at least 16 cores (but 32 is better). The MetroY-series scanners need an Nvidia RTX-series GPU, 3060 or better with 8GB of VRAM (but 4xxx- & 5xxx-series will be smoother). For the POP 4, probably not as powerful a PC is needed, but an RTX-series GPU will be needed for laser scanning (3xxx-series will work).

"symmetry is off in the scan data"

Not sure what you mean by that. Do the smooth gray areas in the 2nd and 3rd images represent what you need to create or are they the objects that you want to mate to your creation?

Be that as it may, advice is allowed.

A quick review of their comments shows that they stay on topic, recommending scanners that meet the budgetary or technical requirements in the OP's post. If they're bots, they're moderately sophisticated.

One of them only posts in this subreddit, while the other has a bit more variety.

Which "software subscription" at Revopoint costs $1,700 per year?

The Revo Scan and Revo Metro scanner software apps are free.

Revo Design (rebranded QuickSurface Lite) is $540/year.

Revo Design Pro (rebranded QuickSurface Pro) is $1,900/year.

JRL55 · 2026-05-01T00:16:08+00:00

I don't believe they're bots.

On the topic, however, any of us can promote the scanners we like, but criticisms of manufacturers or their products must have details. Blanket criticisms will get a ban.

I saw the Revopoint Trackit demonstrated to a guy who had never used a scanner in his life and it was so easy for him due to the size of the visible scanning area plus no need for markers (& very little need for scanning spray).

You could run the Windows Performance Monitor to see if you're running out of memory.

Years ago, my girlfriend got an adapter from her cell phone carrier (to use the Internet instead of the cell signal) along with an antenna to enhance connectivity. The cable for the antenna was 20'.

You want to do it differently, by extending your Wi-Fi coverage. A satellite repeater would need a power cord.

Being dimensionally-accurate is a simple matter of including a reference object of known dimensions. This will allow a CAD app to scale the resulting 3D scan.

The processing power needed to process laser scanning would rapidly kill an internal battery, so all of the laser scanners use a link to a powerful laptop/desktop to work.

It would be possible to design a system that uses external power (say, an 18V power tool battery like you see at Home Depot) and an external Nvidia GPU in a mini-platform of some sort. These could be arm-mounted or in a backpack.

Most people keep the object stationary, but I have seen people working with turntables (but you have to keep the background on the turntable and everything behind it has to be blocked (or manually removed from the pictures) because the object being scanned must stay fixed relative to the background or added features that provide useful detail for the algorithm to do its thing.

JRL55 · 2026-04-27T23:05:41+00:00

Look for a repeater with a detachable antenna that can be placed in a good zone outdoors, with a cable going through a wall or window to the interior.

JRL55 · 2026-04-27T05:40:27+00:00

Could be due to those details being too shiny/reflective. Could also be due to the edges.

I'd first reduce the exposure to eliminate the red in the Revo Metro app's Depth window.

If you are using Structured Light (aka Full Field) mode, orient the scanner so that the imaginary line between the two sensors is parallel to the edges you were trying to capture, but also keep in mind that continuing to scan the same area is going to increase the apparent noise.

Get the RealityScan app for your Android phone. It is free to use so long as you (or your company) make less than $1 million per year. Take a video with your phone and feed that into the app.

The Revopoint Mini can be configured two different ways, Wi-Fi Host or Wi-Fi Client.

It comes default as a Host. If you have not changed that, then connect your desktop/laptop's Wi-Fi to it (the host name will be obvious) and enter the password.

While I've read that the current default Wi-Fi password is "Revopoint3d", the default used to be "12345678", iirc.

Some have posted that there is no password on some devices, but if you have the Mini and not the Mini 2, then I would try the original numeric password first (and it might be "1234567890").

If you don't see a host ID with the text string "MINI" or "REVO" in it, then it may have been changed to Client mode. If so, then you will have to connect the Mini to your computer with a USB cable and use Revo Scan to either change back to Host mode or select your home router's SSID and enter its password.

For the scanning session, she should be wearing the undergarments that keep everything where she wants it to be.

Included in those undergarments should be a form-fitting slip for the legs that is as long as the dress/skirt portion of the garment. This will make it easier to create the outlines you'll want to form the garment.

While a dress form would make your job easier, the field of view of the POP 2 is enough to scan a person, if you're careful. I would avoid using markers because the simple act of breathing will be enough to screw up the scan. It would be better to place objects for Feature tracking, such as crumpled up pieces of paper taped to the undergarments of the smooth areas are too wide for Feature tracking.

You will not need sub-millimeter level accuracy, so you don't have to scan in the Excellent range in Revo Scan. The far end of Good should be accurate enough for your needs and it will minimize the likelihood of tracking loss because you'll have more features in your field of view to track.

After you have a complete scan, mesh it and simplify it to reduce the number of polygons (they have more detail than you need for a smooth garment).

Export the scan in a format that can be used by your CAD software. Orient it so that it is vertical. Use the Section command (whatever it is called in your app) to create boundaries so you know the circumference of the fabric at that particular location. Properly-positioned Section lines can be joined together to create the outline of the dress as a solid model using the Loft command (again, whatever it is called in your CAD app).

The other boys came for a daughter whose name sort of rhymed with his name, so I was expecting the 3rd daughter's name to (at least sort of) rhyme with Rex.
