Automatic Projector Calibration with Embedded Light Sensors

[limanaid]

This guys very impressive, He SERIOUSLY needs some kind of award.

[lugit2001]

Why does the first top comment have less likes than the second?!?!?

[WillParry79]

Ok where can I get something that uses this?

[toie323]

fucking nerds I used to beat up tags like u

[imdxlr8r]

@toie323 Pffff.....'tags'? Shut up loser.

[rpglover101]

@toie323 Without nerds, you wouldn't have a computer or internet to troll with. Heck, we wouldn't even have electricity or lights. Now shut the fuck up.

[animes25]

I cant wait when it can calibrate at 30 fps

[DoctorDustPHD]

That is cool!!

[treva31]

That is SO cool!

[thresisball]

Amazing work!

[peavri]

@jcl5m Amazing is the calibration pattern horizontal and vertical by using half. I don’t know it is possible but you can use different spectrums of visible light (or not visible) and shot all simultaneous and then separate by a prism and done the process all at same time virtually. I see a problem for larger resolutions; you may need to spend more time in the calibration process.

[hmzLOL]

i want to see real time tracking so you can use any surface as a moitor

[frogyofrogproduction]

this i a million dolor idea

[automateanything]

wow!

[toadill]

Have you thought of putting the projector inside a disco ball or a sphere so that it mirrors the projection to everything around you. You could then wrap the screen the whole way around the player and have a 3D world if you included the head tracking technology.

[ogatramastef]

incridible!!!

its just incridible

[85Degrees]

Wow Johnny you are THE man!!

[needabloodyname]

i bet this guy has a tiny asian dick

[hellothango]

@needabloodyname I bet you have a tiny wrinkled brain

[AxelTiger]

Please dont sell out! Keep your ideas and market them under ya own company! :D

[BogartTv]

@AxelTiger meh i hope he sells out so this can go commercial quicker. Hes gonna need funding

[Kurru]

What framework was used to do the warping and translating at 3:00?

[theemmettkeegan]

the practical applications are endless!

[KenRogiers]

what projector is he using??

[danchik1998]

You know what - you can use this and the wiimote trick to get an full sceen multi-touch interactive whiteboard. how cool can that be, huh?

[Starioshka]

GOD DAMN ASIANS! HOW DO THEY WORK?!

[hassmann2000]

wow

[nagrom97]

Amazing!



[Zencyde]

Clever use of fiber optics. Love it.

[7thAttempt]

I wonder if you could use light which is outside of the visible spectrum for the calibration. That way the user wouldn't have to be dazzled by the calibration test and would simply see the pre / post orientation transition after the screen was moved?

[smokinpoolshark420]

Brilliant!

[chrisdavisdesign]

How can I get my hands on the calibration software and the binary mapping pulse. Also can this kind of software be linked to head tracking in anyway. One more thing could anyone give me a list of the components I would need to do this myself.

Thanks

[mrtn474]

@chrisdavisdesign he has all that info on his website and other videos

[chrisdavisdesign]

@mrtn474

thanks

[noptic]

That shit he did with the car blew my goddamn mind. Oh god that's insane.

[Automobilie]

Now I can look forward to the future!

[akcityboy]

i rig A/v screens all the time at work, and would love two be able to attach four led fibre lights(or whateva ther are) to each corner of the screens we hang, and get the unit to sort out the keystone etc, it's takes 5to ten mintues to do each screen, that's after you rig the projector exactly perpendicular to the screen....good idea mate

[LukeWhitaker]

imagine having a tv any where? crazy smart dude

[xXmarv08Xx]

U r a damn genius!!!! Make a homepage with a forum to discuss about this. Is the calibrating software free or do you keep it for yourself xD

[jlo138]

So I can just place some sensors on my wall and my projector wherever I want it to be and I can calibrate it to display on my wall perfectly. Thus being able to make any room a theater room though limited to size of the room. Then being able to place the projector wherever you want without it having to be a specific distance from the wall or even perfectly parallel or horizontal to that wall. THE POTENTIAL IN THIS!!!

[EnZtricks]

wow i want to c wat this transforemd to 7 years later

[swissdude101]

Wow

[RuokangasBrasil]

Johnny Lee is revolutionizing the way we use our every day technology, and i dont know if anyone noticed, but all this 2 projector calibration and head tracking can be used to develop the all time wanted "REAL" 3d hologram with human interface possibilities.

- the computers wasnt created just out of chips, but the copper, the transistor, the capacitor and others.

[alston2reel]

OMG This is the greatest thing ever

[Ratznium]

This guy is the contemporary equivalent of Nikola Tesla. Amazing.

[Fragacide]

Your videos never cease to amaze me... I believe using a mirrored reverse projection would boost over-all quality, and doubling that with the multiprojector idea to eliminate any stitches, you could easily create a 360 degree video display. It'd be like a semi-sphere that you'd have to step in to, but the applications for having a non-stitched 360 degree display are limitless. The projector would simply calibrate a mirrored image on the back of the sphere's (more like a dome, really) surfaces.

[Mauser91]

A lot of potiential.And this was done in 2003??

[MsTreasuredChest]

it's about time science invented magic, sheesh

[philipp7pc]

Guys, You are amazing!

[luv6pup]

as always, amazing!

[TheFXGuy]

Wait... couldn't you do 3D scanning with this?

[StRoRo]

This would be great for home ultra wide dual projector systems.

[wolfhomme]

I think there is a phone that already does that. Remember the video was added in 2007

[CharliesName]

I'm over impressed O.O

[alhamdanfilms]

please make a tutorial

[AnarchiveMagnetik]

You and me , Pink Floyd trip on the road lol ... Big show with big Computer and creativity , we need revolution in software ,,, thx for share  Respect

[FKnox123]

somebody give this guy a nobel

[oalternativo]

I am no engineer.

All I can say about this is "amazing"!

[hellomyfriend2053]

An example of commercial potential, you should look into flight simulation for companies and patent the design. I've been looking for something that can focus on curved and angled surfaces, and I finally found one. I'm sure there's a big market in simulation especially teamed up with other invention of your at fantastic prices!

[fredb3]

This guy xD

[chiurox]

Videos like this should have millions of views... not those stupid pop stuff that's on MTV.

[Dani3lsaurusrex]

@chiurox i know right!

[bahsura]

BRAVO!

[jfunnyshit5]

this is Amazing

[hackerisslv]

It makes yor life much easyer to adyust the image to screen :P

Lol in my school teacher need allmost 10 mins to add correct position of the video :D

[cyberlord64]

You sir are my HERO!!! How the fuck do you come up with these ideas? at 3:55 i was like WTF???

[Pleatherwill]

I love your idea.

With a projector capable of manipulating a non-visible wavelength, the calibration could be done unobtrusively.

[Zeldaplink]

where i can buy it? :D

[cheler88]

amazing ! but... is it only me or is this guy naked ??? 4:03

[cmMerlin]

FANTASTIC!!  I especially like the idea for stereoscopic visualization needs, where calibration is absolutely critical. I hope you patent that invention and we can soon find it in all projectors! :-)

[VideoSiim]

You'll be a millionare one day. :)

[nawkwan]

"This is useful for touch screens by reducing the visual impact of shadows" is it because the 2nd project will remedy the occluded/shadowed regions?

[HiGhDaRrEn]

Thats amazing

[spidfire]

Could you say what kind of chips and optic fibers you did use?

[andylinkproductions]

omg thats so percise you dont even know is projected!!! woot woo wow

[bispro89]

Man, I Improved yours. See me demonstrating mine. Hope you enjoy it!

[abcabcabc314]

ur a genius!!!!!!!

[rdalben]

Congrats on all your POSTS...!! keep up the good work !!

[macbooksexy]

this can help me so much, nice job man, by any chance do you think it will be able to get the software and the other things that make this work? Nice job, keep up the good work.

[halflifeproductionz]

fucking amazing!

[bitmap303]

great work!

[steven9red]

when I go to collage I want his type of job

[goo4oog]

WOOOOOOOOOOOOOOOOOOW

you are very smart i really like your car piant jop LOL

Thank you .

[ringlol]

This is just so amazing, send me one for my room thanks :)

[obone01]

wow! If only I had the computer knowledge to pull off projects like this!

[123adrianramirez]

I wonder what his computer can do! O.O

[paradigmmaker]

and i call myself a computer systems engineer

[llllMoneyMakerllll]

HOLEY F!!!!!!

[kwerrewk]

UH - MAY - ZING!

[CJWild8]

very cool bro, i love the shadow elimination

[sanleito]

amazing!!!!!!!!!!!!!!!!!!!

[wertstahl]

Love it!

[JonazVK]

Awesome!

[cuteEevee]

Thats just asounishing. o.o

[Djluv5]

nice

[vfxguru001]

Awesome work! Thx, MistaLee.

[noneyet77]

ok so johnny do u know that ur a amazing cus u r and who helps u with all this or do u have a team

[kantjeuh]

how can i build that myself? :)

[eloid777]

I like to get info on the software require to run this and the circuit... johnny please provide more details, i have check your web site there not details..... avail to make this.

[TheDvloper]

hi Johnny, I just saw you solutions and found it amazing. Thanks by your idea! One thing I notice, and I don't know if you or someone pointed (because it seens pretty obvious) is that you can have a glass table with a translucent white paper and the wii remote below/inside it, togheter with the projector so you you not have any blind area!

[UnitedTulips]

Johnny Lee never fails to amaze! :D

[Muscleduck]

Imagine the multi projector function in combination with some fullHD beamers. Awesome. Maybe something for flightsim fanatics, or the headtracking. Projection on a 180° dome with multiple beamers.

[MrOnix9009]

OmGGGG This is a majour breakthrew now you can put porn anywhere

[barry4666]

can u use it with a dvd player?

[fotosafariclub]

am interested in this... anyone can make this thing, let me know.

[fred0322]

i like it

[potkettle]

Stunning, Johnny, stunning. And this was nearly 3 years ago. Have you got anyone to pick this up?

[PropellerBusted]

When he shows the car at the end...Oh my God! It's like the future!

[Arcrave]

nice!

[ktwhitley]

Can you use any projector for this??

[nrdesign1991]

you guys are geniuses!

[kinc456]

sweet

[TadeuszOlejnik]

holy shit... dude.. ur a genious... i have been working my ass off on dimentions and the idea of 4th dimention being time... i hope ill find some inteligent answers like u did with ur field of knowlage... its increadibly impressive and i hope u know u are so far the most technologically advanced person on youtube :P

thx for sharing.. its great !

[t3hStorm]

4:02 o.O are you nude?

[griffgriff100]

That is soooooo cool

[xxRukUSxx]

Once this goes real time the world will be one giant step closer to the futuristic utopia we see in all those sci-fi movies.

[howcin]

thats so cool

[urmasterjohn]

How can you retain sharpness if the projector is not parallel with the screen? Surly you loose focus (since the angle will change focusing distance) in a real world environment when your throw is say 1-2 metres diagonal

[ShootOnFilm]

Impressive! But, does this imply that a small screen target area only actively uses a portion of the projectors pixels for the image, and leaves the outliers as black pixels?

[urmasterjohn]

Like all projectors do regardless of calibration. They all must have excessive pixels to take other image factors like keystone into account.

[ThaTyger]

I think it does. Completely refocusing and reshaping the entire projector resolution would take to much processing I recon. But it's a good question and I'd love to hear the awnser to it.

[archanshah]

Johnny Chung Lee!!! Man! you are amazing! i saw your all videos.. those are just mind blowing... keep working and please keep posting! Thank you!

[yawangle90]

there's so much commercial potential in it,

[spider853]

there's so much creativity in it ,

[Burletonboy]

great

[pogobull]

WOW

[urmasterjohn]

Make this into a product!!!

Even the home cinema application for this is excellent. No need for professional installation.

[crunbinklins]

This is absolutely awesome. I wish this was affordable enough for DIY.

[starbkh]

not very impressive but good.

[Burletonboy]

idiot

[starbkh]

just my opinion. don't reply like that.you stupid.

[Burletonboy]

"you ARE stupid" lol

[starbkh]

you stupid

[makaono]

No, YOU STUPID is right. you fucking dickhead!

[bayXSonic]

Insanely good, but I've seen a much better implementation at some Expo a few years ago. I cant remember what name was but they were using a Surface-like table, hovering the "display" over the table would show the image tilted instantly.

Now that I remember I saw it in some of Chris Pirillo's video in 2007.

[sshhh12]

thats epic! I love this video! Thanks man.

[CroaqSS]

omg you are a genius... i love your vids

[gilius]

Im agree!!!!

[RetroZine]

one word... genius!

[tictactactics5]

Calibrating...

*Byyyyarrrmm. Wyyyyrarrmmm.*

Welcome to the future everyone.

[mingping]

Completely amazing...

[jordanfish]

the calibration is so satisfying to watch.

[pedrofile91]

fuck me i want one

[fotosafariclub]

fantastic.... where can I buy the calibrator?

[ctoon6]

nice, love the car thing

[DJBlackedHeart]

that guy is just simple genuis

[maxheadroom1987]

This is just insanely amazing! It's unbelieveable!

[saabmackan]

Magic!

[DaveThePianoDude]

Noo - linear algebra!

[snotclot]

george, there are a few advantages. First, you can have one projector and many cheap receptors such as the one shown (much cheaper than full LCD's) and project onto different surfaces at different times.

2nd, see the part at the end where they project a custom paint job PLUS tire details onto the car. Can you do that with a LCD ?

[georgelpreput]

The science behind this is great, but conceptually speaking, this whole thing is overly dumb. If you already have a CABLE attached to the surface, why not have an LCD instead of the electronically-enchanced projection surface? I guess price could be the only answer, but even that does not necessarily hold up, if you think you're also replacing the projector itself.

[CherryBurstLesPaul]

I agree with you, although I still think it's pretty cool. And the use of this system at the three dimensional car seems rather useful.

[maxheadroom1987]

You could also connect the screen wirelessly to the laptop or have the cable plugged in once and then removed.

[TacoForPaco]

Yes, but this an expirement, not an actual product. It needs refining but it is still cool.

[pyrox23]

Transmitting enough information to calibrate can be done with not much power consumption, and over a wireless link -- say, Bluetooth -- and then the screen can go back to sleep, only to wake up if it gets moved or a refresh is requested by the user. Since the technology to do this already exists and is robust and ubiquitous, the CMU team probably decided it wasn't worth reinventing the wheel.

[wubby5]

this was 2 years ago, wonder how much improvement has been made. . . great vid!

[mavamaarten]

OH MY GOSH !

This is just amazing.

ALL of your projects are great !

[nludwick1]

Nice work guys, cool stuff

[Kargoneth]

Holy mackerel! That's awesome!

[FixiousMaximus]

You sunuvabitch. Stole my car idea!

[weetrip]

Wicked!

With 2 projectors as widescreen that was Impressive!

[dyldyljkj19]

This is just amazing!

[TraumaRabbit]

this must be hella tight, i can see this to check out how a car would look like with a differant paintjob in real life without having to paint it or too see what u wud look like wearing a new sweatshirt before buying it

[Blueninja33]

That would be awesome! Just get a generic whie long sleeve shirt with strategically placed sensors on it and project the different clothes that you are shopping for onto it! SWEET!

[Excelsoft]

fantastic idea!

[Joeybsmooth]

What could this be used for ?

[texture6]

I see Military USE !!!! : ) we're fucked !!!!

[Solis1112]

that is SICK

[jpomail]

sell it, find some one who will buy it, and sell it, make you some monies

[biowerks]

Im sure that your career is skyrocketing by now. congrats.

[ssneibart]

this is epic

[insanoscopic]

Amazing. That really embodies good innovation, readily available technologies rethought. Very impressive. Good work! :)

[reelfour]

You sir, are a genius. Any sign on when this could become commercially available? How could you use this technique for matching the physical geometry of architecture?

[RatbagMC]

Especially loved the projection onto a 3D model.

[kiravintio]

We're not worthy! We're not worthy! *bows repeatedly*

[HertzSine]

This is the definition of elegant. Cheap and flexible sensor system, a little software magic and off the shelf parts combined for a very useful feature.

[dayglo98]

holy cow you just KICK AASSSS !!!! Awesome work
