玩转树莓派[06:USB摄像头和motion实现监控]

这篇文章主要为大家详细介绍了树莓派使用USB摄像头和motion实现监控，具有一定的参考价值，感兴趣的小伙伴们可以参考一下。

本文实例为大家分享了树莓派使用USB摄像头和motion实现监控的具体代码，供大家参考，具体内容如下

一、工具

1、树莓派
2、USB摄像头

二、操作步骤

0、连接并测试USB摄像头

树莓派接USB摄像头十分简单，毕竟树莓派是Linux系统的卡片电脑，将买来的USB摄像头直接连在树莓派的USB口上，然后我们看看摄像头是否被识别，有两种方法：

1. 使用lsusb命令

pi@raspbian:~$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 1871:0101 Aveo Technology Corp. UVC camera (Bresser microscope)
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

SSH终端会显示树莓派当前接入的USB设备列表，我们可以先不插摄像头，lsusb，然后插上摄像头lsusb，就可以看到USB摄像头对应的是哪个设备了。

2. 查看设备文件


也可以查看设备文件，输入命令：

pi@raspbian:~$ ls /dev/video*
/dev/video0  /dev/video1  /dev/video10  /dev/video11  /dev/video12  /dev/video13  /dev/video14  /dev/video15  /dev/video16

3、本人实测摄像画面。

安装mplayer，终端运行：

sudo apt-get install mplayer
sudo mplayer tv://

注意事项：须在安装vnc桌面情况下查看⚠

1、安装motion

sudo apt-get install motion

2、配置motion

(1)让motion可以一直在后台运行

sudo nano /etc/default/motion

将里面的no修改成yes，让motion可以一直在后台运行：start_motion_daemon=yes

(2)修改其他配置

一些常见参数：
daemon on                        #开启守护进程（选配）
target_dir /home/pi/motion-images    #图片保存的路径
#videodevice /dev/video0            #摄像头设备（默认）可修改            
stream_localhost off                 #允许通过网页查看摄像头
stream_auth_method 2               #开启密码认证
stream_authentication 用户名:密码    #网页查看摄像头的用户名和密码

具体修改如下：

sudo nano /etc/motion/motion.conf

修改配置文件，这个文件比较长，请确保一下参数的配置。在nano编辑器下，可以使用^w快速查找到如下配置内容。也可以使用^v向下翻页。

开启终端启动和后台模式

网页端口

监控宽度高度

3、启动motion

sudo motion

4、查看视频数据

在局域网内的设备，不管是手机还是电脑，均可打开浏览器访问树莓派IP:8081

5、退出motion

killall -TERM motion

或者

service motion stop

6、 设置为开机运行（选配）

sudo vim /etc/rc.local

在exit 0前添加 motion , 保存，就会开机自动运行了。

# Only put the options that are unique to each camera in the
