python简单照相机调用系统摄像头实现方法pygame

python简单照相机调⽤系统摄像头实现⽅法pygame 如下所⽰：
# -*- coding: utf-8 -*-
from VideoCapture import Device
import time
import pygame
from pygame.locals import *
import sys
pygame.init()
size = width, height = 620, 485
print size
speed = [2, 2]
black = 0, 0, 0
if pygame.display.get_init():
print ("inited")
else:
print"notinit"
pygame.display.set_caption('1111')
screen = pygame.display.set_mode((600,500))
SLEEP_TIME_LONG = 0.0
cam = Device(devnum=0, showVideoWindow=0)
print cam
filename = "test.jpg"
while True:
for event in pygame.event.get():
if event.type== QUIT:
sys.exit()
elif event.type== KEYDOWN:
key = pygame.key.get_pressed()
if key[97]:
filename = "test" + int(time.time()//1).__str__()+".jpg"
print filename
cam.saveSnapshot(filename, timestamp=3, boldfont=1, quality=55)
elif event.type== MOUSEBUTTONDOWN:
pass
elif event.type== MOUSEMOTION:
pass
elif event.type== MOUSEBUTTONUP:
pass
#cam.getImage(0, 0, "bl")
cmd="shut"
Image = pygame.image.load(filename)
#screen.fill(0,0,200)
screen.blit(Image, (0,0))
pygame.display.update()
time.sleep(SLEEP_TIME_LONG)
希望⼤家多多⽀持。
