Python:通过摄像头抓取图像并自动上传至新浪微博
最后更新于:2022-04-01 19:39:37
通过上一篇文章[《Python:通过摄像头实现的监控功能》](http://blog.csdn.net/dyx1024/article/details/7243956),突然想到将每次采集到的图片可以直接上传至微博,然后可以通过手机准实时查看要监控的地方,实现思路如下:
a.程序A 每30s通过摄像头采集一次图像,并保存;
b.程序B也是每30s将采集到的图片上传至新浪微博;
实现如下:
1. 采集图像程序A:
~~~
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from VideoCapture import Device
import time
#最多保存5张抓取到的图片,超过5张,覆盖最早的那一张,依次循环
MAX_PIC_NUM = 5
#抓取频率,30秒抓取一次
SLEEP_TIME_LONG = 30
#初始化摄像头
cam = Device(devnum=0, showVideoWindow=0)
iNum = 0
while True:
#抓图
cam.saveSnapshot(str(iNum)+ '.jpg', timestamp=3, boldfont=1, quality=75)
#休眠一下,等待一分钟
time.sleep(SLEEP_TIME_LONG)
#超过5张,则覆盖之前的,否则,硬盘很快就会写满
if iNum == MAX_PIC_NUM:
iNum = 0
else:
iNum += 1
~~~
2. 上传图片到新浪微博程序B:
~~~
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from weibopy.auth import OAuthHandler
from weibopy.api import API
import ConfigParser
import time
MAX_PIC_NUM = 5
SLEEP_TIME_LONG = 30
def press_sina_weibo():
'''

author: socrates
date:2012-02-06
新浪微博:@没耳朵的羊
'''
sina_weibo_config = ConfigParser.ConfigParser()
#读取appkey相关配置文件
try:
sina_weibo_config.readfp(open('sina_weibo_config.ini'))
except ConfigParser.Error:
print 'read sina_weibo_config.ini failed.'
#获取需要的信息
consumer_key = sina_weibo_config.get("userinfo","CONSUMER_KEY")
consumer_secret =sina_weibo_config.get("userinfo","CONSUMER_SECRET")
token = sina_weibo_config.get("userinfo","TOKEN")
token_sercet = sina_weibo_config.get("userinfo","TOKEN_SECRET")
#调用新浪微博OpenApi(python版)
auth = OAuthHandler(consumer_key, consumer_secret)
auth.setToken(token, token_sercet)
api = API(auth)
#通过命令行输入要发布的内容
# weibo_content = raw_input('Please input content:')
# status = api.update_status(status=weibo_content)
# print "Press sina weibo successful, content is: %s" % status.text
iNum = 0
while True:
#上传图片,名称和内容如果重复,open api会检查,内容采用了取当前时间的机制
#图片名称从0-5循环遍历
status = api.upload(str(iNum)+ '.jpg', time.strftime("%a, %d %b %Y %H:%M:%S +0000", time.gmtime()))
time.sleep(SLEEP_TIME_LONG)
if iNum == MAX_PIC_NUM:
iNum = 0
else:
iNum += 1
if __name__ == '__main__':
press_sina_weibo()
