Python code for surface inspection is supposed to used especially for agricultural products, which requires Flir(previously PointGrey) USB3 camera with Spinnaker SDK, and PySpin, python module(1.26.0.31) with Opencv, PyQt5, PySerial, and etc. It is capable of Color Correction, Binarization, Lens Distortion Correction, and multiple ROI processing. The color Correction is implemented with OpenCV.mcc and OpenCV.ccm (i.e. Color Correction matrix) from MecBeth Color Chart. As well as the Lens Distortion Correction provides generic model as options of fisheye, and omnidirectional model in the form of modified opencv ccalib package. The Binarization is capable of look and feel control by RangeSlider with sliding both of lower, and higher values.

Would you like to add a udev entry to allow access to USB hardware?
If this is not ran then your cameras may be only accessible by running Spinnaker as sudo.

Launching udev configuration script...
This script will assist users in configuring their udev rules to allow
access to USB devices. The script will create a udev rule which will
add FLIR USB devices to a group called flirimaging. The user may also
choose to restart the udev daemon. All of this can be done manually as well.
Adding new members to usergroup flirimaging...
Usergroup flirimaging is empty
To add a new member please enter username (or hit Enter to continue):
