树莓派usb摄像头网络监控(定时拍照+网络存储)

(一)树莓派使用USB摄像头

说明最好是linux下能支持的uvc摄像头,我用的uvc301的摄像头,linux下一般免驱。

1.首先更新firmware:

rpi-update是老外开发的一个更新树莓派firmware的工具,很方便也很好用,推荐给大家!
  红色部分是需要输入的:
  $ sudo apt-get update      
  $ sudo apt-get install ca-certificates
  $ sudo apt-get install git-core
  $ sudo wget http://goo.gl/1BOfJ -O /usr/bin/rpi-update
  $ sudo chmod +x /usr/bin/rpi-update
  $ sudo rpi-update
  Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS
  Performing self-update
  Autodetecting memory split
  Using ARM/GPU memory split of 192MB/64MB
  We're running for the first time
  Setting up firmware (this will take a few minutes)
  Using SoftFP libraries
  /opt/vc/sbin/vcfiled: error while loading shared libraries:libvchiq_arm.so: cannot open shared object file: No such file or directory
  If no errors appeared, your firmware was successfully setup
  A reboot is needed to activate the new firmware
  $ sudo ldconfig
  $ sudo rpi-update
  Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS
  Performing self-update
  Autodetecting memory split
  Using ARM/GPU memory split of 192MB/64MB
  Updating firmware (this will take a few minutes)
  Your firmware is already up to date
  $ sudo reboot
备注:
09-18版本以后的官方镜像都集成了rpi-update工具,直接执行“sudo rpi-update”就行了,不需要再安装了


2.插上usb摄像头,输入 ls /dev,  查看dev中是否存在一个video0这个设备,如果有了说明系统识别了,如果不认,重复第一步确保firmware最新,还不行就换摄像头吧


3.安装mplayer,输入
sudo apt-get install mplayer

4.输入命令播放摄像头视频(可能是我摄像头没调好,显示出来很花。。。。。。)

sudo mplayer tv://


5.安装强大的网络监控软件motion,输入

sudo apt-get install motion (如果安装不了的,可以先sudo apt-get update 一下)

6.配置motion,编辑motion.conf文件
sudo vi /etc/motion/motion.conf (或者运行sudo xedit /etc/motion/motion.conf)

7.找到”control_localhost on “和”webcam_localhost on“这两行,改为以下两行后,保存退出
control_localhost off
webcam_localhost off

8.运行motion软件,输入

motion -n

9.在pc上用IE浏览器打开, 192.168.99.53 是我的树莓派ip,换成你们自己的
配置网页:http:// 192.168.99.53 :8080


监控网页:http:// 192.168.99.53 :8081


(二)树莓派玩家5分钟内将树莓派-USB摄像头与Yeelink连接–最好玩的网页监控器

5分钟一点也不夸张, 在你熟悉Yeelink使用的情况下, 你真的只需几分钟就可以搭建一套在线图像监控, 神马入室小偷啥的, 还能逃过你的千里眼 当然, 要是使用motion来获取图像, 还能做到画面动作检测, 有兴趣的同学可以继续发挥哦. 废话少说, 来看看几分钟怎么做到的吧.

1. 将USB摄像头接到Pi上, 安装驱动, 我所使用的版本(2012-10-28-wheezy-raspbian.img)已经包含了V4L2驱动, 略去xxx字. 有问题的话Google一下

pi@raspberrypi ~ $ ls -l /dev/video0  crw-rw---T 1 root video 81, 0 Jan  1  1970 /dev/video0

2. 安装抓图软件fswebcam

pi@raspberrypi ~ $ sudo apt-get install fswebcam

3. 登录Yeelink, 在用户中心增加一个设备, 再为之增加一个图像传感器.

4. 在/home/pi下准备脚本yeelink.sh, 内容为以下两行命令, 其中的ApiKey和URL请改为自己设备对应的信息.

sudo fswebcam -d /dev/video0 -r 320x240 --bottom-banner --title "RaspberryPi @ Yeelink" --no-timestamp /home/pi/yeelink.jpg
curl --request POST --data-binary @"/home/pi/yeelink.jpg" --header "U-ApiKey: xxxxxxxxxxxxxxxxxxxx"http://api.yeelink.net/v1.0/device/1022/sensor/1294/photos

为脚本增加可执行权限

pi@raspberrypi ~ $ chmod +x yeelink.sh

5. 将脚本加入cronjob

pi@raspberrypi ~ $ crontab -e

加入下面一行, 让脚本每分钟运行一次, 保存退出.

*/1 * * * * /home/pi/yeelink.sh

搞定, 至此我们的监控就开始运行了, 上网页上看看效果吧

(三) 利用bypy实现树莓派NAS同步百度云

详见http://www.cnblogs.com/xiaowuyi/p/4051238.html。

Bypy是一个百度云/百度网盘的Python客户端,主要的目的就是在Linux环境下(命令行)同步百度云盘空间。Bypy要求python2.7以上版本,最新版下载地址为https://github.com/houtianze/bypy

一、bypy安装

1、所需环境

python 2.7x

python requests库(安装该库需要setuptools 和pip)

2、安装

(1)python 2.7 不在详述

(2)requests库安装

首先安装setuptools

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

如果安装过程中出现问题,可能是没有安装zip解压的原因,zip如何安装请百度。

然后安装pip

https://pypi.python.org/pypi/pip 从这里下载pip-1.5.6.tar.gz

tar -zxvf pip-1.5.6.tar.gz

python setup.py install

安装完成后,pip install requests。实现requests的安装。

(3)安装bypy

直接从https://github.com/houtianze/bypy下载解压就可以了。

3、使用

(1)第一次使用

要把系统的区域编码设置为UTF-8

vi /etc/sysconfig/i18n
将原内容改为:

LANG="zh_CN.UTF-8"
SYSFONT=latarcyrheb-sun16

设置token:

./bypy.py info

or

./bypy.py --disable-ssl-check info

程序会要求你访问一个网址,获取你授权码,授权后复制code给程序,程序会利用不同的服务器进行认证,认证成功会显示百度网盘的容量,如果一次没成功,可以多试几次,容易被墙。

这时百度网盘的“我的应用管理”下会形成bypy文件+。

安装完全后,可以使用./bypy.py list 来看一下列表。
