# This is a demo program showing CameraServer usage with OpenCV to do image
# processing. The image is acquired from the USB camera, then a rectangle
# is put on the image and sent to the dashboard. OpenCV has many methods
# for different types of processing.
#
# Warning: If you're using this with a python-based robot, do not run this
# in the same program as your robot code!

import cv2
import numpy as np

from cscore import CameraServer


def main():
    cs = CameraServer.getInstance()
    cs.enableLogging()

robotpy-cscore is already installed on the FRCVision Pi image, which I would seriously encourage you use instead of trying to set it up yourself.
