I want to use Range 2 to scan parts of a room (walls, floors). But in marker tracking mode there is too much work to insert markers. Is it possible to use Feature Tracking, but at the same time project (for example, an LCD projector) some original static pattern onto the wall. Will tracking work according to the pattern in this case or is it only necessary to change the geometry?
The scanner is working off of the IR light reflecting back. You will not change the IR light reflected back based off another light pattern. It needs to be a physical object that reflects the light.
If you don’t want to mess with markers and prep, maybe consider the new Trackit. But I get wanting to use the tools you have available. Other options I’ve seen people employ are marker nets, blankets, or sheets covered with markers that can be moved.
Is this to map the room for structural reasons, or just to plan it? If the latter, if you have access to an iPhone Pro (12-16) then their LiDAR Scanner is great for that purpose with a free app like 3D Scanner App or Scaniverse.
Hi @Etar
Range 2 is not made for this kind of job as the recommended scanning size is not bigger than 2 meter , you will need to scan things in sections anyway.
3D structured light require features to keep tracking so walls or floors are not the object here of interest , you will get more quicker by just modeling them instead.
But if you really need it for any reason you will need to create some tracking points at least 8 cm apart from each other and couple of them visible at any time .
And it can be anything , from simple cubes you can place on the floor to a painter tape on the wall .
I would like to use Range 2 for measuring rooms when making furniture, when there are some difficult moments with the walls.
As far as I read the documentation, the size can reach 4x4x4m, which is quite enough for my purposes.
Neither for scanning a rooms with empty walls . Not the kind of technology you need. At that size of volume the measurements going to be so off that it will be totally worthless even if you some how succeeded capturing it at once in that dimension.
You have 2 choices , markers or add geometric features to be able to do it , there is nothing else .
Sadly, but it’s not mentioned anywhere that the measurements will deteriorate depending on the volume. It looked good in the advertising brochure, but in reality it’s not quite so. Thanks for the clarification.

That why you need to scan in smaller sections to avoid that .
That is completely normal behavior with structured light scanners .
The provided accuracy is only valid at a specific volume and distance per scan/session
