/home/erik/Luxonis/depthai-python/examples/Calibration/depthai_calib_backup.json
Calibration Flash Successful

Setup

Please run the install script to download all required dependencies. Please note that this script must be ran from git context, so you have to download the depthai-python repository first and then run the script

git clone https://github.com/luxonis/depthai-python.git
cd depthai-python/examples
