Drivers for my Alvium USB cameras

How to run

1 camera

To run just 1 camera simply run in a terminal roslaunch pp_alvium_driver rgb_only.launch or roslaunch pp_alvium_driver nir_only.launch. The launch files should also work in your IDEs (tested on PyCharm Pro).

2 cameras simultaneously

To run 2 cameras simultaneously:

1. run roslaunch pp_alvium_driver rgb_only.launch in a terminal
2. then open another terminal, and run conda activate <<virtual env>>
3. in the activated conda's <virtual env>> run roslaunch pp_alvium_driver nir_only.launch

The whole point for the virtual environemnt is that I could not manage to use alvium's VimbaPython/Examples/multithreading_opencv.py to get the desired frequencies for both cameras. Things start breaking up when my second camera wants to achieve fps > 20 Hz

Remarks

1. Instead of a typical config.yaml file, you set up your config directly in the scripts/*.py files. Enter your camera ID as cam_id, desired frequency frequency and the camera calibration file yaml_fname
2. Install Vimba_4_2 to a desired python as instructed by VimbaPython/Install.sh
3. Make sure that GENICAM_GENTL64_PATH points to path/2/vimba/Vimba_4_2/VimbaUSBTL/CTI/x86_64bit
4. This code has been tested on python 3.7 and python 3.8
