Very informative and interesting topic

Yes, I have heard about structured light or time-of-flight sensors. no use of them

No direct design with image sensors or cameras in the past

 

designed  many image sensors with different image chip sensors

Iron

Yes, many years ago.  Familar with but have not used TOF or Structured Light.

Iron

Robots Rule

 

or at least they will

Hi All,

 

looking forward to another great lecture

Very interesting presentation.  Thanks.

Iron

GREAT LECTURE.   THANKS

 

Thanks Eric; very good lecture

Iron

OK, just finished the archived audio. Thanks Eric and Ann.

I've been interested in some hobby type vision projects because they are inexpensive and being a hardware guy at heart, building the circuit on a breadboard is natural.

Low resolution vision systems can be put together with off-the-shelf MCU development boards, a few chips and some software.

Iron

time-of-flight sensors is something we use here all the time in Guided Wave RADAR tank level gauging. RADAR depends on precise time of flight measurements.

Iron

 

Thank you for today's presentation

Do individual pixels on CMOS sensors have lenses on it?


Some do,  not all.

Blogger

More sensitive, or more pixels? Or is it as simple as having a larger aperature in front of it, to handle the larger sensor size?


Sensitivity is proportional to pixel area.  A larger sensor of the same resolution will be more sensitive.

Blogger

The resources described on your page 28 -- are those supposed to be active clickable links?

No,  just google the paper titles.

 

Blogger

Do individual pixels on CMOS sensors have lenses on it?

Is there any spec about viewing angle, like in discrete photodiodes?

Iron

Okay. Diving back in tomorrow.

Platinum

More sensitive, or more pixels? Or is it as simple as having a larger aperature in front of it, to handle the larger sensor size?

Platinum

 Is there a big difference between 1/4"  and 1/3" inch CMOS sensors in the cameras when it comes to vision analysis?


Generally, the bigger the sensor the more sensitive it is to light.  A 1/3"  sensor would be more light sensitive then the 1/4" sensor.

Blogger

The resources described on your page 28 -- are those supposed to be active clickable links?

Platinum

TOF = Time of Flight.  It measure the time it takes a pulse of light to emenate from a source, bounce off an object, and be seen by a camera.  Very simular to RADAR.

March 2012 Embedded Vision Alliance Summit Technology Trends Presentation on Image Sensors
May 17, 2012

BDTI Senior Engineers Eric Gregori and Shehrzad Qureshi deliver a techology trends presentation on image sensors for embedded vision applications, at the late-March 2012 Embedded Vision Alliance Summit. Eric and Shehrzad discuss trends regarding conventional 2-D image sensors, as well as those supporting "3-D" (depth discernment) and "4-D" (i.e. selective focus, otherwise known as light field or plenoptic) functions.

Blogger

@Eric: I'm sure you're right, but there are a wealth of video lectures there that might take some time to sift through. Can you give a one- to two-sentence description of what TOF sensors are in this chat?

Iron

Good lecture.  Seemed short...

Iron

Thank you Eric!
Table on slide 22 shows the "Time of Flight" type of 3D sensor that was not covered in your lecture... Are you planning to talk about it in the future lectures?

Iron

@Eric: Great lecture, and excellent slides. One question I had (and I realize I may need to resubmit this tomorrow) is that "Time of Flight" 3D sensors show up on the Summary slide (slide 22) without previous reference, introduction, or comment in the audio. Would you care to describe TOF sensors and distinguish them from Structured Light and Stereo 3D sensors which you did introduce earlier?

Iron

You can download the "Software Demo" used in the Thursday and Friday class here:

http://www.embedded-vision.com/what-embedded-vision/embedded-vision-academy/type/downloads

Blogger

So which link do I click on to download the code for the future sessions???

Iron

thanks for the discussion.

 

Iron

Thanks for the info.  It was worth the wait.

Iron

Good infos, thanks Eric

Iron

Pretty cool stuff, thank you!!

in IT things do happens No big deal...

Iron

1. yes 2. used structure light. heard of tof

Again, very sorry for the technical problem today with the audio.  

You should be able to access the recorded audio now.   If not, please let us know.

I recommend that everyone follow today's lecture from the recording at your convenience, and bring your questions from today's lecture to the Q&A session following tomorrow's lecture.  Alternatively, you can email us your questions at info@embedded-vision.com.  Also, feel free to post questions on tomorrow's classroom page prior to the start of the lecture.

Blogger

I have not heard of structured or time of flight sensors in those names...

Iron

I have not designed with image sensors or cameras before.

Iron

Eric, etc, you may want to cover -- ah, waited long enough, you got to it -- the bit about normalizing pixels. I suspect you'll mention later about cancelling out known-defective-pixels...

Platinum

Listening to the recorded audio now.

Iron

I hit the play button before and I get the looped audio and keep wanting to bump the turntable, showing some age here.

Iron

@wwbrown, if you click the "Play" button on the red block at the top, it'll start playing the archived lecture. You may need to click F5 to refresh and re-sync your browser window.

Platinum

Thank you, Eric.

I think everyone can listen it now individually.

See you all tomorrow!

 

Iron

Listening to it right now... Just finished going through the slides (MUCH prefer the PDF instead of powerpoint; good move). Was amused -- you remember yesterday I asked about LeapMotion? They are doing a 3D sensor play with jawdropping precision (repeatable position-determination of 0.01 millimeters, ten micrometers). THEY aren't saying a whole lot about how they do it, but the only bit I'm missing at this point is whether they are using more than one CCD sensor (some element of triangulation, possibly). Infrared light, lenseless, shadowmask, calibrate with an empty field-of-view speckle pattern which is constantly applied to NEW sensor frames; the intellectual property is the algorithms which extract position and distance data from the sensor stream.

Platinum

Where is the link to the recorded audio?

Iron

Also, feel free to post questions on tomorrow's classroom page prior to the start of the lecture.

Blogger

Thanks Jeff, time to get back to work, so will listen to the audio later and have Q's for tomorrow.

Iron

Again, very sorry for the technical problem today with the audio.

The recorded lecture is available now... What a difference (no &^*%*! laptop radio)!

Iron

Can I integrate OpenCV into an Android device?  

Absolutely.  Check out: http://developer.nvidia.com/category/zone/mobile-development

Blogger

1. No, not used. 2. No experience with structered light or time of flight sensors

Iron

Archived audio did work fine. Hopefully we have live audio for tomorrow.

Iron

just started with an inroduction and goes to live chat in few seconds

I have not designed in the past. 

Iron

No - not used; no experience with structered light or time of flight sensors.

Everyone: I'm very sorry for the audio problems today.  I've escalated the issue, so we won't have a repeat tomorrow.

The (time-delayed) audio stream is now available.  Try refreshing your browser on this page.  The full lecture is recorded and is available now.

Blogger

I suspect it's going to be pretty quiet in here, if everyone is trying to fast-forward through the archived version...

Platinum

OK, getting the archive audio now.

Iron

I would highly recommend the book: "Machine Vision: Theory, Algorithms, Practicalities" by E.R. Davies

 

Blogger

Ah man, bring back the BlogTalk Radio chickie!

 

Iron

So Eric was continuing on as if audio was OK? Hope the recording was successfull and not just 30 min of the looping.

Iron

Works on IE but not Firefox

Iron

Yes, it is starting now

 

Iron

Refresh browser. Lecture working now

Iron

audio buffering but not working

Hard to ask questions on a lecture we didn't hear - Oh well, will post them before class tomorrow so maybe they can be addressed then.

Still buffering on the audio as well.

Refresh now and you can catch the lecture from the beginning.

The archived version is now available.

Iron

No audio yet, just buffering

Ann has just given the "now we'll all go over to the Live Chat Page" closing statement.

Platinum

Yes, Eric continued his lecture so it will be available in the archive in just a few minutes:

http://www.designnews.com/lecture-calend

 

Blogger

i think i'll listen it offline

looping is gone, now only slight hum/static after browser refresh

Iron

I guess I get the closing statement only. I'm sorry I couldn't hear the lecture.

Audio now ended -- refresh your browser though

Iron

See you later,laterlater......need a cup of Sumatra 

Iron

It HAS stopped. If you hit F5, you'll re-sync.

 

Ahh, the DESIGN East in Boston.

 

Ann, do we assume that Eric has been speaking all along???

Platinum

Looping stopped when I refreshed browser. Now there's just silence... eerie.

and ... right at the end of the presentation! great ...

i refreshed the page and now it works.

are we undergoing a mental experience?

 

refresh your browser, audio has arrived

Maybe now we can go to a more standard audio stream technology
Iron

Has not stopped. You must have muted your audio.

Iron

Back in the mid 80's, I implemented an embedded vision system to recognize and identify vehicles.  The application was a Toll Collection system in South Korea.  The drivers there recycle everything and stuff cardboard, etc between the cab and trailer or wherever they can.  We took pictures of all the vehicles sold in Korea and used fourier transforms to calculate probalities that a vehicle in the lane was of a certain toll class. 

www.linkedin.com/in/bobbalchrealtimefirmware

Come on, guys, this is embarrassing -- I talked you up to a forum full of people interested in sensor technology and associated tools, and I'm getting razzed on a back-channel here...

Platinum

So, Eric will wind up recording his session w/o an audience and we'll all have to listen to the archive.

Iron

The looping has stopped!

You can check out any time you like, but you can never leave.

 

I saw a multi-Kinect system that put each Kinect on a little motion platform. Since the camera and image projector are a single unit, each one sees its own light fine, but all other light from the other Kinects is an ignorable blur. Neat solution. 

@Ann: Thanks.

@Eric: Note that on slide 7 "pixel element" is a redundancy - "pixel" is short for "picture element".

Iron

Got work to do.  I'll get the archive of this later.

Ann, Eric, Jeff, no worries, see you tomorrow.

"So, an engineer, a consultant, and an audio server walk into a bar..."

@RichQ, yes, there are, but not every implementation uses them.

 

Even better is when you take a look, google "lenseless imaging shadowmask", you get some serious "structured light" opportunities -- and if you add in "speckle" you get even BETTER stuff. Turns out, apparently, that if you capture a shadowmasked CCD chip speckle image with nothing in the field of view, then ADD something, the CHANGES in the speckle field can in fact be processed to extract a TON of useful information.

Platinum

It's BDTI just trying to brainwash us, really.

 

 

Iron

The presentations looks good.  Logging off. 

Iron

Ok. I give up... can't take any more "lap top radio"...

Iron

I'll wait for the archive, bye

I'll get the archive and try again tomorrow. The audio is driving me nuts.

Iron

Make it STOP, make it STOP... I can't take it anymore! ;)

things happens, nothing perfect...

Iron

MATERIAL TO STUDY: ANY TEXT BOOK ON SIGNAL (DIGITAL?) SIGNAL PROCESSING. WIKIPEDIA HAS QUITE A BIT OF MATERIAL, BUT A GOOD TEXT BOOK WILL HELP TO SET A SMOOTH LOGIC SEQUENCE.

Iron

@ Eric, the presentations looks good, I'll log in and listen to the archive when it is available.  Thanks for setting up this course.  Maybe tomorrow will work better.  see you then

Iron

We're working on an audio fix. In any case, you can access archives of each day's lecture on this page:

http://www.designnews.com/lecture-calend

And please continue to post questions here so Eric can answer them in the second half of the show.

I'm sing Lap Top Radio in the Rain

I'm singing in the Rain.

Ba ba booo

Ba ba beee

I guess the archive will be available in 1 hour

Iron

Have you heard about structured light or time-of-flight sensors? Have you evaluated or used them?

Heard about it, but never used it.

Iron

@flaredone, I though there were CMOS sensors with global shutters, which eliminates the kind of scene variations you mentioned

Platinum

MAX: I wen to their site yeaterday and downoaded a cheatsheet of processor comparisons. I think the high end ARM would work.. Defintely some of the Highend TI chips

Iron

We just need a disco beat in the back and we could use this for a rave.

Iron

I wonder if she'll take a break talking during dinner...

Have you dug into the OpenCV website? They have a LOT of useful info, including stuff about what platforms they are currently working with. They also have some pretty useful tool kits (I downloaded 150M zipped tool kit which allows me to monkey around with images on my PC).

Platinum

Thank You, Had a Brain Cramp from the Lap Top 

Iron

@Ann: is the actual lecture being recorded now? If so, can we be notified by email when the archive is available? If not, can we be notified as to when the lecture is rescheduled?

Iron

Is thera a dial up audio instead?

 

Gentlemen, maybe somone can give an advise related to the subject:

what Math is used(maybe some books are the best to go in deep)?

 

Iron
Didn't miss anything did I?
Iron

Yes, OpenCV is portable onto Android

Iron

Have you designed with image sensors or cameras in the past? If so, what was your biggest challenge?

My biggest challenge was selecting the lens ... mostly due to my lack of knowledge in optics ...

Next biggest challenge was getting a clean image ... on several occasions, with different image sensor manufacturers, there always seemed to be an obscure setting that got the image cleaned up, but was not intuitive to find in the datasheets

Iron

the comments have never been so entertaining

Iron
Good afternoon everyone.
Iron

She does sound kinda hot, doesn't she.

 

Iron

The issue I was hoping to get some insight on is how to improve the resolution of a camera sorting for defects in Zinc coated tubes.

Iron

seems their audio server could use some new Intel processors  :-)

Iron

I've started to whistle this catchy little tune.

Iron

Can I integrate OpenCV into an Android device?  I'm not familiar at all with CV and looking for starting points and what hardware to use.  I'm building a car infotainment system for myself, and it needs video processing feeds.

Platinum

Now if this was an actual Alert you would go to LAP TOP ......I forgot 

Iron

This is actually just an exercise - you have apply the first level of processing described yesterday to "Plop Tote Radio" to hear the actual lecture.

I wonder if she's (Blog Talk Radio gal) married, I'm single you know.   :)

@ANN: WHAT IS THE WORD. DO YOU THINK WE CAN CONSIDER THIS A COURSE TIME? IT IS ALREADY 2:16 pm AND MOST OF US ARE IN THE LIMBO. WHY DON'T WE RESCHEDULE THIS?

Iron

I am going to be dreaming about a laptop radio tonight.

Iron

Is there an engineer in the house?... just askin' ;-)

Iron

Am I the only one with a repeating "Lap Top Radio" on the audio link???

Iron

How do I make use of OpenCV on a mobile device (something with a front facing camera)?  Are typical ARM designs powerfull enough to use?

Platinum

If we can get past the audio issue ("pause" it, guys) we MIGHT be able to get SOME useful discussion??

Platinum

@codeslayer: It grows on you.

 

You will be assimilated - just listen closely to the interesting messsage :)

Have you tried turning it off and on again?

The size of the sensor changes the processing requirements.

 

Need to be cautious distinguishing between CCD and CMOS -- one of them gives a "full frame at once", the other one CAN give a "rolling" capture (which makes variations in lighting stand out like a sore thumb).

Platinum

I think I'm going insane, and I'm really starting to like BlogTalk Radio for some reason.
