Python opencv 视频图片添加时间戳

图片添加文字

import cv2
img = cv2.imread('pyyy.png')
img2 = img.copy()  # 备份操作

font = cv2.FONT_HERSHEY_SIMPLEX  # 定义字体

imgzi = cv2.putText(img, '000', (50, 50), font, 1.2, (255, 255, 255), 2)
                  # 图像,文字内容, 坐标 ,字体,大小,颜色,字体厚度

cv2.imshow('origin',img)  # 显示原始图像
cv2.waitKey()

cv2.imshow('putText',imgzi)  # 显示添加文字操作的图像
cv2.waitKey()

cv2.imshow('backup',img2)  # 显示原图像的备份
cv2.waitKey()
cv2.destroyAllWindows()

视频显示时间戳
