A very strange scanner. Firstly, I bought it to scan a room, but as it turned out, it is not capable of scanning surface planes without markers. Okay, I needed to scan a bracket made of black plastic, at least in something I thought the scanner would help me. Do you think it was scanned, no, absolute zero. I do not understand why such a scanner is needed in principle?
Can I get my money back and buy myself a couple tons of popcorn?
Hi @Etar
A 3D scanner is made to scan a 3D objects and not flat planes , 3D objects that are difficult to recreate , a plane or a room is not . Markers can still help with that but this scanner is not made for scanning rooms and never was advertised for it
Infrared based scanners do not scan materials that absorb infrared , for that reason you need to use 3D spray when dealing with surfaces like that , there is not much you can do with physics in this case.
I guess you should do better research before purchasing a 3D scanner for your specific needs . Or follow the scanning rules and learn little more about what you have in your hand in place of complaining , because the only thing that failed here is you and nothing else. Wrong tool and wrong expectations without proper research
It is sadly not the scanner at fault here .
For question regarding your money back please contact customer@revopoint3d.com
If you are still eligible for a full refund there will be no problem .
Let’s be honest, advertising always shows only the strengths of a product and never the weaknesses. When I look at cars, the ad does not say that it can drive on mud, sand and even shallow water, but it does, although not fast. When I buy a pump, the ad says the maximum pressure, but does not say what exactly I can pump with it, a ball, a tube or something else, in any case, it will cope somehow. But the 3D scanner turns out that it scans normally only specific objects, with high reflectivity for infrared rays. Show me where in the ad it says that it cannot scan flat surfaces or dark objects. But it is beautifully shown how it scans a water scooter without a single marker))
Hi Etar, Being that commercially available hobby 3D scanners are a relatively new tech, compared to the examples that you provide above, most people would research their products’ capabilities, e.g. resolution, scanning area and weak and strong points! And the advertisers have to make some assumptions about people who are looking at advertisements for 3D scanners. I mean only a fool would just go spending money on something they have no concept of how it works and have the gall to spend the time moaning about the fact. I mean, on the same page that they purchased it on, there were ads for more expensive ones that use a blue laser. Why would you buy a more expensive one? @PUTV gave you a way to make it work e.g. scanning spray, and all you can do is come up with, let’s be honest! Mate, you need to be honest with yourself.
Caution! Hot coffee is Hot! who knew!
OK ill get of my soap box now
@wazza77 Don’t push the horses(c)
If you don’t like the topic, move on. There is no need to pretend to be a professor who combs the entire Internet in search of strengths and weaknesses before each purchase.
Before purchasing this scanner, I studied the available information about the scanning volume of 4x4x4 m and the frame size, the frame resolution of 0.1 mm and 0.3 mm for frames. And according to these characteristics, it suited me very well. I also compared its characteristics with other scanners. So it’s not worth saying that I didn’t study the information. Maybe the manufacturer indicated that it cannot scan flat objects or dark objects?
But in some ways you’re right, I’m a newbie in 3D scanning and did not take into account some nuances, for example, the impossibility of scanning flat surfaces without markers, and this is exactly why I wanted to buy it.

lol man, scanning a room was possible back in 2014 with a Kinect from xbox. And there were no losses of position, the resolution was really complete nonsense…
All the best.
Hi @Etar
This is structured 3D scanner and none of this type of scanners can scan flat surfaces without markers , the newest Revopoint 3D scanner Trackit is the first of own kind that allows you to scan any surfaces without markers , but regular infrared scanners like Range series or Miraco can’t do it from a technical point of view because they relays on features to be able to scan anything and keep tracking . If the features are not available the markers can be used to replace the features .
And seriously who need 3D scanner to scan flat planes ? When you can recreate it in second in 3D editing software with the highest precision .
Materials like resin, wax, rubber , oil paint and black plastic are materials that absorb infrared , and usually only laser scanners are able to scan them since they have higher power like 2M class laser , infrared is only 1M class so not powerful enough .
You see how the scanner is working is projecting a pattern on the surface using infrared DLP projector , if the surface absorb the light pattern , the scanner sensors can’t see it .
The same thing when you try to project a movie on a black painted surface , you barely will see anything . Got that reason how more matte and brighter the surface is, how better the sensors can see it , for the same reason you use 3D spray to prepare the surface for the best results and that is common knowledge.
There is solution to do everything you want , the question is , are you willing to learn ? Because if you do our community here is to help you out
3D scanning is the most expensive 3D service for a reason , if that was so simple to just buy a scanner and do the work without any knowledge , I would lose my job of 30 years ..
and coming back to your early questions .
Can 3D scanner scan flat planes ?
Here’s why flat planes can be challenging and how to overcome them:
Challenges:
Lack of Features:
Flat planes often lack the geometric features (edges, corners, etc.) that 3D scanners use to align scans.
Alignment Issues:
Without sufficient features, aligning multiple scans of a flat object can be difficult, leading to inaccuracies.
Potential for Error:
If the scanner relies heavily on the flat surface itself for alignment, it can be prone to errors and drift.
Solutions:
Markers:
Applying markers (stickers, tape, or 3D-printed blocks) with distinctive patterns or letters can provide features for alignment.
Scanning Spray:
Applying a thin, even layer of scanning spray (e.g., foot spray, dry shampoo) can create a texture on the surface, providing more data points for the scanner.
Scanning Mats:
Using a mat with a printed pattern or markers can help with alignment and registration.
Feature Mode:
If the scanner has a feature mode, using it in conjunction with markers or small objects placed around the flat surface can help.
Multiple Scans and Post-Processing:
Capturing the flat object from multiple angles and then using specialized software to stitch the scans together (post-processing) can create a more complete and accurate digital model.
In essence, while flat planes don’t inherently provide the best data for 3D scanning, with the right techniques and tools, they can be successfully scanned using structured-light technology.
I hope this little info helps to shine the light a little bit on your progress to become successful 3D scanning expert ! And keeps you curious enough to not give up .
BTW I use Range only for medium to big objects , it is not suitable for scanning small objects , the features or markers need to be placed at least 6-8 cm apart from each other and at least 3 of them need to be visible at all time in the frame . Consider this when scanning objects making sure the features are there to begin with .
@PUTV I heard you and have no complaints about you. You always try to help.
But let’s get back to the sheep. You ask why scan flat surfaces, the answer is simple - a furniture designer needs to take measurements of the room. And sometimes the room is either complex in shape or has uneven walls or floors and it is very difficult to do this with ordinary tools.
Now about structured light, Kinect also has structured light, but it scanned flat surfaces perfectly and did not lose its position.. how so?
UPD. I have an idea to use electrostatic film to apply markers to, this will allow to painlessly apply the film to any surface (almost any), and not tear off the markers.
The Kinect projects a pattern of infrared dots onto the scene. Like markers that why it can scan what it can , but the accuracy is not as good and very much off , iPhone uses this technology for scanning faces for recognition ID , and it is as good as 1 meter distance ( 3 ft) , anything beyond it will be not usable and it uses 30.000 infrared dots . But it is totally not usable to scan precision scans , Range could do that but the accuracy would be so bad , not usable for your project. I was there with it while testing the product before release.
Revopoint technology has own invention by projecting 2 patterns , vertical lines that moving quick from left to right , the lines provided greater accuracy and precision but require tracking.
For your job you need some precision and accuracy, and not above 0.3 mm while fusing
So if you are not into sticking tones of little dots , you can try to use some painters tape and create false features on the surfaces , some making small paper balls from it and stick to the flat walls , and throwing some cubes on the floor , you can actually buy white rubber cubes on Amazon , I do use them in some situations .
Just try and experiment , set the scanner in body mode and try , I scanned 8 x 12 half room with Range , but it had furniture and wall decor so the features keeps on tracking easy .
So you can do it , just practice on small area. Keep the scanner at least at good distance maximum so between excellent and good . How far the distance how less features are needed .
That makes a sense and not easy task if the room has different dimensions all around so I understand your needs now much better.
You could use Lidar scan to map the room much better but the costs would be greater as well as Lidar scanner is not cheap and expensive to maintain .
Kinect is also not the answer for you , too bad resolution and zero accuracy .. you would not able to use it proper to build anything based on that .
I did hack Range scanner while it was in pre production and it allows me to scan at 2 meter distance , above 6 ft , but the accuracy was so bad so it was completely useless .
You see , when you project the patterns on the walls at greater distance the lines or dots in case of Kinect become so big that it lose the accuracy . With this technology how smaller and sharper the projection , how higher the accuracy . The reason Mini can scan a coin and Range can’t , because they use different pattern and distances .
I hope you better understand the technology now .
I know what the scanner can or can’t do , so for me no mysteries or surprised here .
Can you do it ? Yes you can but with the proper workflow and little effort .
@PUTV Thank you very much for the clarification.
Relatively new tech your examples were a car and a pump. the first car was German and is coming up on 140 years old and working examples of water pumps were found ind the old workings of the Rio Tinto mine in Spain from the roman era so relatively yes. as for a professor combing the internet yes i can find relative data about object tracking in about 20 min as everyone complains and struggles with flat featureless objects or dark and shiny ones, if you had of looked you would notice some scanners have a mode to deal with dark objects. Its not the topic I don’t like its the attitude that is the “Absolute disappointment” if you realised you effd up with you purchase then sure come on here and ask questions learn from your mistake and move on. But you chose to blame your lack of knowledge on advertises and a product. Own your mistakes!
