Python:通过摄像头抓取图像并自动上传至新浪微博
通过上一篇文章《Python:通过摄像头实现的监控功能》见 http://www.linuxidc.com/Linux/2012-02/54206.htm,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: 2. 上传图片到新浪微博程序B:
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
- #!/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

- 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__':
