树莓派motion摄像头监控并将图片上传百度云盘

sudo apt-get install motion

sudo vim /etc/motion/motion.conf

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

videodevice /dev/video0 //这个可以查看下 ls /dev 如果看到video0则说明usb摄像头已经挂载，可以使用了

#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

Authorizing/refreshing with the OpenShift server ...

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 &
