Opencv with cuda support

Install JTOP

sudo apt install python3-pip

After pip installs:

sudo pip3 install -U jetson-stats

Install jetson containers

# install the container tools
git clone https://github.com/dusty-nv/jetson-containers

The opencv_install.sh has gone so you must recreate it using:

cd jetson-containers/packages/opencv
nano opencv_install.sh

Then paste the following into the sh file:

#!/bin/bash
#

version="4.10.0"
folder="workspace"

set -e

for (( ; ; ))
do
    echo "Do you want to remove the default OpenCV (yes/no)?"
    read rm_old

    if [ "$rm_old" = "yes" ]; then
        echo "** Remove other OpenCV first"
        sudo apt -y purge *libopencv*
	break
    elif [ "$rm_old" = "no" ]; then
	break
    fi
done

echo "** Install requirement (1/4)"

unzip opencv-${version}.zip
unzip opencv_contrib-${version}.zip

cd opencv-${version}/

echo 'export PYTHONPATH=/usr/local/lib/python3.10/site-packages/:$PYTHONPATH' >> ~/.bashrc
source ~/.bashrc


echo "** Install opencv "${version}" successfully"
echo "** Bye :)"

Now run the bash file

bash opencv_install.sh

Now you are ready to compile opencv Then staying in the home directory

sudo ./jetson-containers/packages/opencv/opencv_install.sh https://nvidia.box.com/shared/static/ngp26xb9hb7dqbu6pbs7cs9flztmqwg0.deb OpenCV-4.8.1-aarch64.tar.gz

Run JTOP and you should see
