1706 Vision Solution: Tracking totes in depth-map, color, and infrared

[cameronr2980]

Hello,
I have been trying to get this program running on an nvidia Jetson TK1 for the past few hours. I can't seem to get some of the dependencies to install. apt comes back with an error saying that every package except for build-essential cannot be located. "Unable to locate package x." I have looked around on the internet for a solution and tried a few but none of them have worked. This may be more of a linux question but does anyone see an easy solution to this? I'm thinking about reflashing linux and trying again.

did you try sudo apt-get install libopencv-dev?

Try:

sudo apt-get update

Apt-get gives those errors all the time when the repos aren't up-to-date. What is the command you are running?

Also, I suggest that you compile OpenCV manually for the Jetson because it supports a crapload more of optimizations than other boards. I don't have a Jetson, but I'm sure that it uses the same repository as the other boards, like the ODROID.
The Jetson has CUDA support, one thing that should used to it's max for it's glory! It'll make your code run just a lot faster!

I would love to see the performance of our code on the Jetson. Please someone deliver. I'm willing to thread it and optimize it if someone wants to bench mark it for me.

I've tried apt-get update and apt-get upgrade, both completed just fine and I still had the same error. I get the error from running:
sudo apt-get install libavcodec-dev
I get the error for a couple more packages too, that is just an example. I think that all the problems i'm having are with open CV so i think i will reflash ubuntu and try again, this time compiling openCV myself.

Please try running apt-cache search libavcodec > out.txt and upload out.txt to this forum. That'll search through the repo and possibly output a ton of text! If the package is found, you're golden.

That returns:
"libavcodec-dev - Development files for libavcodec"
as well as several more lines like it describing other packages. I'm really confused now because this means that it found the package, right? But when I use apt-get to try and install it it says it can't be found.

It might be because I'm on the school network now think of it. I'll keep trying.

[cameronr2980]

Now it found every one of the dependencies no problem. No idea what was wrong but thank you all for the help.

hey everyone,

i have some qustion about using the knicet in auto ,but we can't figure if it is supported by the new wpi code (c++)

On the robot, or the driver station? Because if driver station, keep in mind rule G21:

During AUTO, DRIVE TEAMS must not directly or indirectly interact with ROBOTS or OPERATOR CONSOLES.
VIOLATION: FOUL and YELLOW CARD

FIRST salutes the creative and innovative ways in which Teams have interacted with their ROBOTS during AUTO in previous seasons, making the AUTO period more of a hybrid period due to indirect interaction with the OPERATOR CONSOLE. The RECYCLE RUSH AUTO Period, however, is meant to be truly autonomous and ROBOT or OPERATOR CONSOLE interaction (such as through webcam or Kinect™) are prohibited.

we mean to use the Kinect as 3D camera

you have to utilize the libfreenect library in order to interface with the kinect. If you go to our code, cmastudios made grabbing the rgb, ir, and depth map from the kinect into one line of code.

https://github.com/rr1706/vision2015/tree/master/lib the files are free.cpp and free.hpp.

The rgb image is obviously in color (RGB), the ir is in grayscale, and the depth is an interesting type of image, it is grayscale where pixel values are a representation of depth.

Thanks for sharing this. I did get your solution working on a Nvidia Jetson board yesterday.

[faust1706]

I have been stuck on a time consuming project in the lab so I haven't had time to configure it for the jetson board laying on the table next to me. I just stare at it with desire....

How'd it do? On the odroid, we get manageable fps, but it is rather laggy compared to our vision programs in the past that were hitting 30fps.

It could be a factor of the repositories you have enabled... check /etc/apt/sources.list
