问题描述

我正在 python 中尝试使用 openCV，我制作了一个简单的网络摄像头，它只会以黑白显示，但我想知道是否有可能以某种方式将它与不和谐联系起来，所以每当我打电话给朋友时，他看到我是黑色的和白色.`

I am experimenting with openCV in python and I made a simple webcam that will only show you in black and white but I was wondering if it was possible to somehow connect it to discord so whenever I call a friend he sees me in black and white.`

import cv2

capture = cv2.VideoCapture(0)

 capture.set(3, 640)
 capture.set(4, 480)
 capture.set(10, 300)

 while True:
     sucess, img = capture.read()
     img = cv2.Canny(img, 100, 100)
     cv2.imshow("Webcam", img)
     if cv2.waitKey(1) & 0xFF == ord('q'):
         break

推荐答案

这可能会晚，但请检查一下 pyvirtualcam

This may be late but check this out pyvirtualcam

先安装:

pip install pyvirtualcam

你可以这样:

import pyvirtualcam
import numpy as np

with pyvirtualcam.Camera(width=1280, height=720, fps=30) as cam:
    while True:
        frame = np.zeros((cam.height, cam.width, 4), np.uint8) # RGBA
        frame[:,:,:3] = cam.frames_sent % 255 # grayscale animation
        frame[:,:,3] = 255
        cam.send(frame)
        cam.sleep_until_next_frame()
        cam.sleep_until_next_frame()
