That's it!

Clone openpilot and install the requirements

cd ~
git clone https://github.com/commaai/openpilot.git 
# Follow [this readme](https://github.com/commaai/openpilot/tree/master/tools) to install the requirements 
# Add line "export PYTHONPATH=$HOME/openpilot" to your ~/.bashrc 
# You also need to install tensorflow-gpu 2.0.0 and nvidia drivers: nvidia-xxx/cuda10.0/cudnn7.6.5 
# Install [OpenCL Driver](https://www.codeproject.com/Articles/1230011/OpenCL-Drivers-and-Runtimes-for-Intel-Architectu) 
# (Note: the code assumes cl platforms order to be 0.GPU/1.CPU when running clinfo; if reverse, change the -1 to -2 in selfdrive/modeld/modeld.cc#L130; helping us refactor this mess is encouraged) 
# Install [OpenCV4](https://www.pyimagesearch.com/2018/08/15/how-to-install-opencv-4-on-ubuntu/)

Build openpilot for webcam

cd ~/openpilot 
# check out selfdrive/camerad/cameras/camera_webcam.cc line72&146 if any camera is upside down 
scons use_webcam=1 
touch prebuilt

Connect the hardwares

# Connect the road facing camera first, then the driver facing camera 
# (default indexes are 1 and 2; can be modified in selfdrive/camerad/cameras/camera_webcam.cc) 
# Connect your computer to panda

GO

cd ~/openpilot/tools/webcam 
./accept_terms.py # accept the user terms so that thermald can detect the car started 
cd ~/openpilot/selfdrive 
PASSIVE=0 NOSENSOR=1 WEBCAM=1 ./manager.py 
# Start the car, then the UI should show the road webcam's view 
# Adjust and secure the webcams (you can run tools/webcam/front_mount_helper.py to help mount the driver camera)
# Finish calibration and engage!
