树莓派motion摄像头监控并将图片上传百度云盘
sudo apt-get install motion
Daemon = off改为on
webcam_localhost = on改为off （新版叫：stream_localhost）
target_dir /var/lib/motion 照片和录像保存地址，改成别的保存地址 /mnt/udisk/motion 我之前没改，网页http://192.168.1.188:8081/会挂掉
width 640
height 480
webcam_port 8081
framerate 2 自动监控拍照，帧率没必要太高，否则输出的文件很多
threshold 3000 多少个像素发生改变的时候，保存当前照片
#下面这句是说一旦有照片被拍下来，则执行upload.sh命令，
#其中%f参数会自动转化为当前图片文件的路径，传给upload.sh：
on_picture_save /home/pi/baidu/upload.sh %f
sudo vim /etc/default/motion
start_motion_daemon=no改为yes
sudo service motion start 或 restart
查看http://192.168.1.188:8081/
异常：
如果网页http://192.168.1.188:8081图像经常挂掉，可能是保存图片的文件夹权限不正确导致的，可以设置下文件夹属性。

打开网页显示图像，在摄像头前晃晃手，图片挂了。此时：

可以看到提示错误：
[ERR] [ALL] myfopen: Error opening file /var/lib/motion/01-20160417223200-00.jpg with mode w:
这时查看文件夹属性：
drwxr-xr-x 2 root root 4096 Sep 8 2014 motion
sudo chmod 777 motion/
drwxrwxrwx 2 root root 4096 Sep 8 2014 motion
sudo service motion restart
此时，摄像头就正常了。
上传百度云：
将https://github.com/houtianze/bypy里的bypy.py bypygui.pyw setup.py上传到baidu目录里，并chmod 755 bypy.py权限
需要先认证：
pi@raspberrypi:~/code/baidu $ sudo python bypy.py syncup

Successfully authorized 说明认证成功
sudo vim /etc/motion/motion.conf
on_picture_save /home/pi/baidu/upload.sh %f 拍照后执行upload.sh
sudo vim upload.sh
#!/bin/sh
sudo python /home/code/baidu/bypy.py syncup /mnt/udisk/motion
sudo chmod 755 upload.sh
用设置上面的方法不好使，只能用下面的办法，每30秒上传图片到百度网盘，然后删除本地图片 ：
#!/usr/bin/python
import os,sys
import time
while True:
try:
os.system("sudo python /home/pi/alex/code/motion_pic2baidu/bypy.py syncup /var/lib/motion") #这里一定要用绝对路径，不然开机启动会找不到文件，默认是root账户目录
os.system("sudo rm -rf /var/lib/motion/*")
time.sleep(30)
except Exception,e:
with open("log.log","a") as f:
f.write("error!\n")
保存后可直接运行：
python upload.py &
开机启动：
sudo vi /etc/rc.local
在exit 0前加上：
sudo python /home/pi/alex/code/motion_pic2baidu/upload.py &
