[python][原创]opencv读取摄像头或者视频模板代码

先前经常去网上找，现在干脆放博客了，这样我以后测试直接进入我的博客copy即可

摄像头的代码：

import cv2 cap = cv2.VideoCapture(0)

 #获取视频帧速率 FPS frame_fps = int(cap.get(cv2.CAP_PROP_FPS)) # 获取视频帧宽度和高度 frame_width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)) frame_height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)) print("video fps={},width={},height={}".format(frame_fps, frame_width, frame_height)) while True:   ret,frame = cap.read()   cv2.imshow('frame',frame)   if cv2.waitKey(1) & 0xFF == ord('q'):     break cap.release() cv2.destroyAllWindows() 

视频文件的代码：

import cv2 video_file="your file" cap = cv2.VideoCapture(video_file)

 获取视频帧速率 FPS frame_fps = int(cap.get(cv2.CAP_PROP_FPS)) # 获取视频帧宽度和高度 frame_width = int(cap.get(cv2.CAP_PROP_FRAME_WIDTH)) frame_height = int(cap.get(cv2.CAP_PROP_FRAME_HEIGHT)) print("video fps={},width={},height={}".format(frame_fps, frame_width, frame_height)) while True:   ret,frame = cap.read()   cv2.imshow('frame',frame)   if cv2.waitKey(1) & 0xFF == ord('q'):     break cap.release() cv2.destroyAllWindows()
