the occipital structure sensor it's a mobile 3d sensor that allows you to
capture dense geometry and high fidelity 3d models very quickly it has a mode
that allows you to capture an entire room at once and it even lets you play
with some augmented reality games stay tuned for more of that and hit the like
button down below if you want to see us check out more 3d printers in the future
vote for turnip we always say it on the WAN Show buy the shirt it's in the link
in the description down below so why the structure sensor well i've
been really interested in 3d scanners and printers for quite some time now but
usually the best option is like shapeways or whatever and it's kind of
been under that whole too expensive and not really good enough for mainstream or
me yet category yes i know i'm a virtual reality nut but one or two vr dev kits
is nowhere near the cost of a truly awesome 3d scanning and printing setup
let alone the cost of plastics the structure sensor stood out to me however
and i decided that it's time to start getting my hands dirty in the scanning
and printing space unlike most 3d scanners the structure sensor isn't a
contained unit with a spinning platform or a moving camera or whatever instead
it just drops your ipad air 1 or 2 ipad mini 2 or 3 or 4th gen ipad then plugs
in through a lightning connector to the ipad itself and the internal battery of
the structure sensor is charged through power from your mains not the expected
micro usb solution it's a depth sensor using an invisible laser projected
infrared blast an infrared camera to capture and then in conjunction with the
ipad's accelerometer gyroscope and compass it can map out a relatively
accurate depth map that can be put together into a point cloud and finally
modeled if that's what you want these movement-based mechanics really give you
the freedom to scan some very interesting objects that you may not be
able to put into a contained type scanning unit
maybe the material's shape or actually just the material could be the problem
imagine scanning a sand castle for most people this wouldn't be very possible
due to picking up said sand castle and having it fall apart on the way to the
scanner but if you were able to bring the scanner to the sand castle
then you got a different story so 3d scanning mapping entire rooms playing
augmented reality games and maybe some more how well does it do it all let's
find out so this is just the object scanner and you can use your thumbs to
resize how large the box is you don't want it to be too small
because then i'll end up chopping off part of poor terran's head
and you don't want it to be too large because then i'll pick up stuff like the
chairs and the desks so i'm gonna guess it's around here i'll get some of his
shoulders in there and as you can see it'll put kind of this
this white stuff on top of whatever
it has in the scan whatever data you'll get you can notice already that it seems
to be doing a pretty good job but i don't have taran's glasses in here it
doesn't pick up glasses very well because it's clear and the ir light
isn't going to kind of come back to the sensor very well off of something that's
clear when it goes red like that i'm too close so i need to kind of come back
so i just moved too quickly you might be able to see this on the
scanner it says recovering move gently just
trying to patch in some various holes that we have it's coming
along quite nicely actually so i'm going to press stop
it's not that bad really there's i'm it's there's something there's there's
holes here yeah there's holes there color view
there's your it actually did pretty okay with the
glasses a lot better than i expected one thing that i want to clarify before we
do room scanning is that it's kind of designed for an empty room it's not
designed for a super crazy clutter really small room
like this so i'm putting it into a worst case scenario and we'll see how it works
and here we go you'll see it's kind of fun you kind of put everything in the
room into like tron almost
i'm gonna let it look at the inside
so that it can see that those are closet doors
whoa that looks funky i think i moved too
much and it tore wow so it thinks that closet is just insane
all right let's try this again i'm going to try to move less i'm going to try to
not move my position like at all
all right so you can see how much of a better job it did there when it's given
something a little bit more simple it even did a much better job of the closet
it still has a bit more depth than it probably actually has
i don't know that's that's pretty accurate actually now we can try whole
filling that makes it even a little bit better
that definitely did fix some areas the roof fan looks kind of insane on x-ray
view raw cool now let's try the last one
augmented reality so i get this little cat
and balls fall down and i have to try to go get them but because i scanned these
objects in the cat can't go through the mineral oil
bottle as you can see right there cannot go through the mineral oil bottle
but i can go around it it's a rather simple game but this is
basically a dev kit so you can go in here hack the game up
make whatever you kind of want and maybe make something a little bit more
fun than cat chase's ball around bottles of
mineral oil so that was fun but what about a
conclusion the structure sensor is cool and it's definitely fun but how
practical was it well that actually depends a lot on the operator and the
subject things that reflect or absorb a crazy amount may actually cause you some
problems and a shaky inexperienced or impatient operator will result in issues
the fact that the platform isn't the same all the time will leave you needing
to edit many of your scans in relatively minor or sometimes relatively major ways
would i recommend it yes if you need a freeform scanner for
many applications that it could be needed for instead of a contained scanner yes if you have want to have a
ton of fun with it not necessarily if you're looking for the highest potential
scanning resolution and fidelity in the end
speaking of things dollar shave club dollar shave
club is a great way to get razors and other bathroom supplies shipped directly
to your door for only a few bucks a month the razors are high quality and we
have a ton of community members who use them every day and love the smooth shave
that they get no matter how thick or coarse their facial hair may be for some
reason this comes as a shock to many people out there but yes
even though i have facial hair i do shave and i would definitely say that i
get a better shave from dollar shave club razors than those old ones that i
had the razors are pretty darn nice and on top of that the razors also come with dr
carver's shave butter which goes on smooth so you can see what you're doing
and they're peppermint scented butt wipes for men for those of you over here
in north america that can't get your hands on a bidet
