One thing I struggle with though is making sure that the capture is robust enough before I move on. I usually only really know that something is off when the capture is done already. Can I “touch up” an existing capture by doing another local scan of a problematic area?
Unless you want to move all the furniture out of place (even in-built one), all the heavy stuff blocking edges and corners from view etc. Good luck with that bathroom sink or kitchen counter-top.
And angles and inequalities (eg. top edge vs bottom edge), that gets funny fast.
My company uses them to measure prior to use creating build plans for remodels and I used them at my previous company to do high detail measurements in the context of real estate to make 3D tours of homes.
If the iPhone can eventually get to the point where Matterport is today with their tech then that's good enough for a huge number of use cases.
Pretty much everyone in the construction and remodeling industry right now is prepping for that as the future. We all know it's 3 to 5 years away and want to be the first one to get it right.
There are certainly cases where LiDAR approach can work wonders. But as long as you need to do a couple of corrections manually, you'll need to have both set of tools at your disposal.
It will definitely augment current measuring approach (or rather, existing tools will be used to augment results coming from 3D scanning), but as soon as you have to pull out a laser or tape for one edge, your workflow is significantly more complex.
Not to mention that for cases where one might use SH3D, it'd be hard to tell an automated tool to ignore that 2"x2" "tooth" in one corner for just wanting to look at different furniture arrangement.
Basically, my point is that we'll need all three, and workflow won't be trivial to combine them.
But then you need to measure "free standing" wall (when measuring the opening is not an option), and without someone to hold something flat at the other end for the laser to bounce off, measuring tape still wins.
Which is not to say that laser is not extremely useful: I generally use both.
MagicPlan[1] and PolyCam[2] seem to be the most focused on building a schematic level building model which could be imported into other tools if needed. They both now take advantage of the Roomplan API[3] which Apple introduced in iOS and iPadOS 16[4]. MagicPlan has been out for ages[4] and originally just worked off the camera and the accelerometer to help build a floor plan. Polycam also supports photogrammetry[5] where you just take a bunch of photos and it builds a 3D model by interpreting what shape the object could be (I don't know if this is also used in architecture scale things, but it could be interesting for ID projects). Both MagicPlan and PolyCam allow you to tweak dimensions of rooms, doors, windows, furniture, etc. in a somewhat parametric way. This is where you likely want a laser measuring device to quickly update the dimensions. These can be used through Bluetooth to enter the measurements directly into the floorplans in MagicPlan[6]. I didn't try this, but if I was doing this all the time, it seems like it would be essential.
Matterport is starting to get into mobile[7] (phone, tablet) capture, but they've built their business up on their branded hardware and cloud platform. They provide floorplans as a service[8] and everything adds up, but from what I see in the real estate market, they are ubiquitous.
And if you want to spend a bunch more for very pro level app for documenting things like crime scenes, shipbuilding, infrastructure, etc. there's Dot3D.[9]
