OpenCV has support for getting data from a webcam, and it comes with Python wrappers by default, you also need to install numpy
for the OpenCV Python extension (called cv2
) to work. As of 2019, you can install both of these libraries with pip: pip install numpy
pip install opencv-python
More information on using OpenCV with Python.
An example copied from Displaying webcam feed using opencv and python:
import cv2 cv2.namedWindow("preview") vc = cv2.VideoCapture(0) if vc.isOpened(): # try to get the first frame rval, frame = vc.read() else: rval = False while rval: cv2.imshow("preview", frame) rval, frame = vc.read() key = cv2.waitKey(20) if key == 27: # exit on ESC break vc.release() cv2.destroyWindow("preview")
