two-basler-cameras

Code to capture video from two basler cameras simultaneously in python.

Requirements

First, install Basler Pylon Software Suite. After, install the libraries in libraries in requirements.txt. You can use the command:

pip install -r requirements.txt

Using the Code

To test everything is okay, run the file two_basler_video.py. You can import the file to use the functions in your code. For example:

from two_basler_video import video_from_two_cameras

FPS = 20
RECORDING_TIME = 10  # in seconds
FILE1 = "./samplevid1.avi"  # extension can be changed
FILE2 = "./samplevid2.avi"  # extension can be changed
CAMPIXFMT = "Mono8"  # can change to anything available on the camera
VIDPIXFMT = "gray"  # since camera is in Mono mode
CAMEXPTIME = 40000
WRITER = "imageio"  # use either "imageio" or "FFMPEG"

# shoot video
videos_from_two_cameras(FILE1, FILE2, RECORDING_TIME, CAMPIXFMT, 
                        CAMEXPTIME, FPS, VIDPIXFMT, WRITER)

Video Writers

The code gives you a choice to use one of two video writers 'imageio' or 'FFMPEG'. If you are using 'FFMPEG', make sure that path to ffmpeg library on line 75 in FFMPEGwriter.py is correct.

When in doubt, use 'imageio'.
