hi this is ben from magic plan today i want to address two of your most frequently asked
questions how accurate is magic plan's ar scan and how does it perform in a fully furnished apartment
to answer those two questions i'm going to show you a full scan of an apartment
start to finish and then i'm going to compare those measurements to measurements from a laser
measure now this is going to be a pretty in-depth video so if you don't have a lot of time you can
watch our other video on ar measuring right here and make sure you subscribe to our channel to stay
up to date on all of the latest news so let's have a look at what we're doing today due to current
covet restrictions i'm working from home so today we'll be scanning my apartment with approximately
700 square feet it's not a very large apartment it consists of a bedroom a living room with an
open kitchen area one bathroom and a balcony for today's video i'm using the new iphone 12 pro
the 12 pro has the new lidar sensor built in now while you don't need a lidar sensor to use
magic plan it will give you three main benefits one you can automatically detect walls two you
get automatic ceiling height detection and three you just get overall better measurement accuracy
so let's get started the first room i'm going to scan is my living room with that open kitchen area
and to get started in the app i'm going to select scan with camera
i'm going to follow the on-screen instructions and i'm pointing down at my feet to locate the floor
and now i'm pointing at the ceiling and i'm good to go i can just point my device
at walls and anytime i see that green tick come up i can move on to the next one by
doing so i can locate corners even though they might be hidden behind a piece of furniture
if the app at some point doesn't detect the wall like you can see here i can use corners instead so
i'm just pointing down at the floor and the app is locating corners for me and i can switch between
wall and corner mode anytime now what makes wall mode or wall detection really great
is it makes it so easy to detect and find corners even though they're completely hidden right
now wall detection is a feature that is only available on devices that support lidar or
that have a lidar sensor and if you do not have a device with a lighter sensor you can always
use corner detection that you can see right here i'm just going to finish off the room by
using that automatic corner detection and the great thing there is it works even though that
corner is not visible so here you can see that flower pot standing in the way magic plan can
still predict where that corner is now that i've finished my room i finished my perimeter i can
start detecting windows and doors and i do that just by pointing my device at a window or a door
then i can use that slider at the bottom of the screen to define
the door or window type so i just had a glass door this is a hinge door
that's my main entry door to my apartment and this is going to be the last door in this room
which goes to the bathroom and just like that we finished our first room and i'm going to take a
minute here and just make sure the orientation of all doors is correct and then we're going to move
on to the second room which is going to be the bedroom this room is going to be interesting as
well and what's a bit tricky in this room is that i have these sliding doors and the room actually
extends beyond those sliding doors so i have to find a way to actually measure that
i'm going to start off by locating the floor again and then pointing up at the ceiling
now you can see here i'm detecting the first wall and i'm going to point behind my sliding doors
behind that cabinet and i can actually find that wall in the back and i just placed my first corner
and by just scanning the next wall we actually just added the second corner
that's behind those doors now wall detection will also work if you don't see the whole wall
so i'm just pointing at a bit of wall here and i just located that corner over there
and just like that that room's done it's an easy room it just has four corners right
so i can move on to locating windows and doors again just pointing up at that window there we go
and then moving on to the door
we've already got the second room now i'm going to take that room and just
assemble it with my first one and then i'm going to move on to the bathroom
now anytime that you're using the ar scan you want to make sure that you have the
best lighting conditions possible so if you can make sure you turn on the lights
so as the two rooms before i'm going to use a combination of wall and corner detection again
to get this room measured
i just located my first wall and i'm gonna see if that small patch of wall is enough
to actually locate it yeah worked fine now you can see i have that very small bit of wall here
and that doesn't quite look right so i'm going to use the undo button
to go back a step and just place those two corners
now even in the shower corner detection works just fine
and here we don't really know or we can't see where the corner is but the app manages to find it
another easy room with four corners and we're good to add that last door
okay so as before i'm gonna rotate that room and just drag it into place and just
make sure i'm aligning it properly and then as you can see it's not quite lining up correctly
and that's because there is a bit of wall behind there where all the pipes are running so i'm going
to use the filler wall feature that we have in the app to make sure that we indicate that
i just drag that in there wobble around and we're good to go
so now at this point we're pretty much done and there's only one thing
left to do and that's add my balcony it's not really a room but we want to edit anyway
and then we're going to see how the ar scan performs in an outdoor
environment so i'm going to select balcony here and as always start by pointing out my feet and
then up at the ceiling if you don't have a ceiling on your balcony just don't point up
now even here it's a bit messy it's starting to get winter
but you can see even though there's a lot of stuff going on on the floor
the app is actually able to detect the corner i'm just climbing across my couch
and because i can't really see the corner here i'm using wall detection again
and that did the trick so only one more thing left to do and that's point down at that corner
and we're done i'm going to assemble that with the rest of my rooms
and that's my apartment so that whole process took just under seven minutes
i was able to capture all three rooms the balcony and all windows and doors so let's have a look
at the results i logged into the magic plan cloud and pulled up the scan we just produced
i can see all of the measurements we just captured and i can even view this project
in 3d but what about the accuracy for our accuracy test i'm going to be using this bosch
bluetooth laser meter connecting one of these laser meters to magic plan is really easy as long
as they have bluetooth if you would like to learn how to use a laser meter together with magic plan
you can watch a video on that right here and if you're thinking about purchasing a laser meter
check out our blog post on the three best laser meters you can use with magic plan
so what i'm doing here is just selecting the individual measurements and then taking that
measurement with the laser meter all of the measurements are automatically transferred to
magic plan via bluetooth so now that we have the laser measurements we can open up both projects
and see how the lighter scan performed on the left we have our lighter scan on the right we
have our version with laser measurements they look pretty similar but let's have a closer look
at the accuracy for this test i put all of the measurements into a spreadsheet now i'm not going
to go into a lot of detail here but i am going to link this document in the description below
let's have a look at some key metrics though in terms of total area of my apartment we had
an error rate of 2.7 percent and on average for all of the individual wall measurements per room
we were somewhere between two and six percent air what's really interesting to note is that ceiling
height measurements were incredibly accurate we were below one percent error for all rooms
as you can see you can achieve impressive accuracy with magic plan's ar scan in a
really short amount of time if you're going to use that scan to plan a general layout of a space
use it for documentation's sake with pictures and notes or even do a material calculation
for a painting job it's going to be more than enough and if you do need 100 accuracy just
hook up one of these it's really easy i hope you guys enjoyed this video if you have some
