OPENCV libraries for arm #144

Open sergio14890 opened 4 years ago

sergio14890 commented 4 years ago

Hey @doonny and everyone! I need download opencv libraries to compile in arm. Can someone tell me a place or tutorial where i can see how to do it?

mingyi136 commented 4 years ago

@sergio14890 you may have a look on OpenCV documentation: https://docs.opencv.org/2.4/doc/tutorials/introduction/linux_install/linux_install.html

To summarize up, this is the method that I used to install OpenCV on this Linux SD card image of DE1-SoC from https://software.intel.com/content/www/us/en/develop/topics/fpga-academic/learn/tutorials.html

git clone https://github.com/opencv/opencv.git
git checkout tags/2.4.13.3       //as I'm using OpenCV 2.4.13.3 due to CMAKE version available

//Install required packages
[compiler] sudo apt-get install build-essential
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

cd opencv
mkdir release
cd release
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
make -j2
make install

@mingyi136 you know also about this error? I'm try solved it, but i don't can. error

mingyi136 commented 3 years ago

@sergio14890 which command that you are running? Is that to build opencv for ARM?

One more thing, you are running that on Windows?

sergio14890 commented 3 years ago

Yes my big friend, I'm trying to build opencv for arm. I run this command: cmake -DSOFTFP=ON -DCMAKE_TOOLCHAIN_FILE=../opencv/platforms/linux/arm-gnueabi.toolchain.cmake ../opencv

I run this command in the Ubuntu 18.04 to build the opencv for arm. And then I pass openCV to windows and run it on Intel soc eds command shell

mingyi136 commented 3 years ago

Hi @sergio14890 , I'm not familiar with your method.

But for me, I have ran the commands (to build opencv) that I have mentioned before directly on ARM. Also, my run.exe file is generated on ARM as well (not from Windows & EDS command shell).

sergio14890 commented 3 years ago

Hmm ok. One more question, you can connect your fpga to internet? If so, could you explain to me how you do it? Is that I can only connect to a home computer-fpga network Thank you so much!

mingyi136 commented 3 years ago

Yes, you may connect the board to Internet!

For my own way, I have shared my desktop WiFi with DE1-SoC board via LAN Cable (https://www.instructables.com/id/How-to-share-Internet-over-Ethernet-Cable/)

Alternatively, you may also try to download opencv folder in dekstop, then transfer it to ARM (to be built later) using scp command (via LAN cable)

sergio14890 commented 3 years ago

Nice, your help was very good! Thank you so much!

sergio14890 commented 3 years ago

Hey @mingyi136 one last time. I tried to do what you told me.

I have my computer connected to a Wi-Fi network. And I connected my computer to the de1soc board via 1 ethernet cable. I think I set everything up well, but when i try search on google in board, i have error.

eth1 eth2

mingyi136 commented 3 years ago

You are most welcome, @sergio14890

I suggest you to check the connection again by typing 'ifconfig' command in the terminal (ARM). You should see 'inet addr' value displayed on 'eth0'. If not, you may try reconnect it by typing 'dhclient eth0'

You may have a try on bridge connection too if the wifi connection to board still don't work https://www.windowscentral.com/how-set-and-manage-network-bridge-connection-windows-10

sergio14890 commented 3 years ago

Hey @mingyi136 and @doonny, i need your help ... I'm having a hard time connecting my fpga to the internet. I have the following configuration: 

               **wi-fi**                                  **ethernet cable**

Router -------> My Computer -------> De1-soc Board

In configuration My wi-fi i have enable : properties -> share -> select 2 boxs image

And this is IP config: image

When i connect FPGA via ethernet cable i have this automatic ip: image

But, the network stay: unidentified network and public network. image

In putty i confirate: ifconfig eth0 169.254.27.152 netmask 255.255.0

But when i try connect internet, i dont have a sucess. I need help, thank you for sugestions

mingyi136 commented 3 years ago

Have you tried 'dhclient eth0' in ARM terminal? Does 'inet addr' value display on 'eth0' section after you enter 'ifconfig' command in ARM terminal?

When i do "dhclient eth0", the terminal is stuck. I have this wi-fi adaptor in my home: https://www.conrad.com/p/logilink-wl0084e-wi-fi-dongle-usb-20-150-mbps-987133. I'm try connect to my internet with command: ./connect_wpa my_internet_name password, but doesn't work

mingyi136 commented 3 years ago

Perhaps you can try this, it works for me:

  1. First, make sure your Wi-Fi internet connection is unshared

image

  1. Highlight both Ethernet (the one to board) and Wi-Fi, right-click and click 'Bridge-Connections'

image

  1. Wait for a while, then right-click the Ethernet and select 'Remove from Bridge'

image

  1. Finally, make the Wi-Fi internet connection shared

image

  1. Try again with 'dhclient eth0' and 'ifconfig'
sergio14890 commented 3 years ago

I did exactly what you asked for, and I got this result .. image

sergio14890 commented 3 years ago

Do you know if it is normal to have only 1 led access on the ethernet cable port?

sergio14890 commented 3 years ago

Thanks @mingyi136 finally, i solved all problems. I have this kit TRDB-D5M, you know if it's possible open this web-cam in Arm?

mingyi136 commented 3 years ago

Glad to hear that @sergio14890

I didn't try TRDB-D5M before, perhaps you can have a try on that

sergio14890 commented 3 years ago

And with a USB camera have you ever tried? @mingyi136
