Steamkraft | TUTORIAL | Revopoint MINI 2 3D Scanner

I would like to use the MINI 2 to show you how to scan hard-to-reach areas of an object.

MINI 2 is available for buying on Revopoint Official Shop!
You can buy it by clicking the link below:

This is not only for the Mini 2 - but especially when scanning very small objects that are very angled, you always have places that are very difficult to scan.

I would like to use a small example here to show a method for capturing certain areas better.

If you scan this figure in the classic way, you can see that certain areas are not captured in the result:

Position of the scanner:


The area circled in red shows which areas the scanner could not “see”.

To be able to scan these areas as well, you can rotate the scanner by 90 degrees.
It will look like this:

The result if you scan the figure like this is as follows:

Of course, there may be other areas that are not captured in this orientation - but if you combine both scans, you get the data from both scans:

The reason why it makes such a difference if you turn the scanner 90 degrees is because of the way the scanner gets its data.
Here is an example of the whole thing - (here I use a cup because the whole thing comes from an animation I prepared a long time ago)

The projector projects a pattern onto the object:

The pattern is then captured with the left camera:

and the right camera:

In order to calculate the 3D data from this, it is important that the pattern is projected onto the area to be captured by the projector and that the area is seen by the right AND left camera.

To make the whole thing clearer, here from the scanner’s point of view: I have shown the projector as a green light source, the right camera as a red light source and the left camera as a blue light source.

If you now combine all 3 views, you can see which areas fulfill the requirements - they are displayed in white:

This means that only the white area can be captured in this frame.

Now transfer this to the situation where you have crevices that are difficult to reach (as with the figure).

Let me illustrate this with a model of a small vacuum cleaner filter:

when the scanner is aligned horizontally:

you can see that the inside of the crevices cannot be completely captured.:

If you now turn the scanner by 90 degrees:

you can see that the end of the crevices is also captured

So - that was a bit longer now - but I hope it can help some of you


Excellent guide. I do this from time to time to get those hard to reach areas too.

This is a great tutorial, I was having this exact issue yesterday. Thank you so much, I will be trying this, this weekend :sunglasses:

Thank you, This is great information.

Very nice tutorial!

Can you advise to what kind of camera mount that is in order to get this sideways?


Thank you :slight_smile:
I use a camera arm but you could easily use a Mini Ball Head (just search on amazon) :slight_smile:

Great Tutorial, and extremely helpful animation!

@Steamkraft Do you mind if I make a Revopoint official video to tell ppl this smart hack? Will tag your ID in the vid.

sure - no problem. I started a video a while ago but before I could finish it the Revo Scan software version changed and I would have had to adapt it again. Unfortunately, I didn’t have the time so it would be great if you could make a video

I tried with official Tripod and Mount, it seems that if you install the Scanner sideways then you can directly use it sideways.
