Introduction
DragonWally brings two high-resolution cameras to take pictures of the same scene from different points of view. An epistolary geometry algorithm then calculates the distance of the detected objects, based on subtle discrepancies between the two images. Get ready, because this week spoke with the DragonWally team on OpenHours! Cezar Menezes and Cleber Picolo, Engineers from the DragonWally team joined us to talk about their project, the prototype, and their path to creating a product around this awesome idea. We were ultimately presented with several demos and of course took the opportunity to ask questions and address any other 96Boards concerns during the episode.
If you have time to check out the video below, you will see face detection, recognition, cat detection, cloud computing, stereo vision and depth sensing/calculation and much more! Be sure to check out the many resources, videos and chat low below.

Hi, Robert. Good Morning!
Hello, Cezar! Are you ready? :D
Cezar Menezes - CM
I hope so. Countdown ! Finishing the setup here.
Robert Wolff - RW
nice
Let me know if you would like to test anything
Ragnar. - R
Hi Cezar. May the demo gods be with you.
Cezar Menezes - CM
Hahaha. Demonstration Effect, go away !
We're testing cameras (Laptop, USB Cam) and screen sharing. I hope our internet speed is OK.
! :P lol @ragnar
Ragnar. - R
Robert hi, any news from my Santa Claus?
Cezar Menezes - CM
T minus twelve ...
lol
I was just messaging you on IRC
You havent recieved anything yet?
Let me ping him

What Coursera course have you mentioned?
Shovan Sargunam - SS
@laxman I have muted you. Please let me know if you want to talk
laxman - L
its okay
thank you
Ragnar. - R
And then you (as you said) need to calibrate and not just let the cameras dangle free.
Sujai - S
what is the typical value of T ..is it same as distance between the human eye.
Rafael Christ - RC
I would like to ask a question
Ragnar. - R
The distance they use is less than between our eyes. ~5cm I think.
Sujai - S
i see.thanks Ragnar.
Sahaj Sarup - SS
disabling composition in the desktop will help as well
Robert Wolff - RW
I think ideal distance between cameras is 80mm
Sahaj Sarup - SS
reduces load on the gpu significantly
Robert Wolff - RW
witch is the width of the 96Boards conumer edition spec
which*
Sujai - S
but the distance will depend on the FoV of the lens
Mani - M
@sahaj: we should put up a doc for disabling LxQT rendering in guides section

will the board get 2 separate camera streams or (ie.) will DB410c see these 2 cameras as 2 v4l2 devices.
or will the board provide a single camera stream (single v4l2device) to the DB410c
Mike Levine - ML
Need to jump off but thanks! Very interesting.
Sujai - S
is the algorithm running on the DB410c CPU?
very nice to see the performance
thanks.
Carl - C
mount it on a drone?
Robert Wolff - RW
@Carl yes!
Todd Thal - TT
Can u take questions ?
Ragnar. - R
makes sense - dragons can fly
Mani - M
Robert has a black cat ;-)
Carl - C
the dragonfly
Ilo Rivero - IR
You could implement the cat detection function to track wild animals in a Forest.
Carl - C
deer populations - great idea
Keith Lee - KL
When the application goes headless, you could put it on the new Altera 96Board and use a soft vector processor for computer vision and distance measurement.
Mani - M
Are you utilising GPU for running OpenCV?
Sahaj Sarup - SS
would it be possible to maybe have the camera distance adjustable using sliders or somthing
Rajan - R
we had a request for cow tracking, basically take car asset trackers and put them on cows
Carl - C
so many uses - ocean buoys
Todd Thal - TT

Neural Networks need lots of positive and negative samples (million of images).
Todd Thal - TT
Don't know if million dollar challenge is mentioned ...yes children can do ...our best tech CAN NOT (yet)...quantum Comp problem ...
Mani - M
Thanks @cezar
Gotta go. See you guys nexr week
Rajan - R
gotta go, cheers guys
Cezar Menezes - CM
Thank you
