想给3D打印机做一个“监控”,能够在手机上查看打印情况。最简单的想法就是给它旁边放个摄像头,虽然可以买一个,但看到用树莓派结合摄像头就可以实现,于是试着做了一下。
用树莓派调用摄像头的程序有不少,但motion似乎用到的还挺多,还可以检测画面中是否有物体在运动。这样后期可以调用画面的变动来检测是否打印完成。打印完成后,可以调用物联网模块切断电源。
安装motion时遇到了不少问题,现在整理一下安装方法以及遇到的问题及处理方法。
一、安装方法:
打开树莓派的设置面板,将摄像头启用。这一步既可以在终端用 sudo raspi-config 进行,也可以在GUI界面进行。这一部分可以百度查看。启用摄像头后重启树莓派。如果用的外置USB摄像头,不用重启,但注意是否需要安装驱动,我用的是免驱摄像头。
我的安装图如下:
然后将树莓派系统更新到最新版,然后输入以下命令进行安装
1 |
sudo apt-get install motion |
安装过程中会要求输入Y进行确认。
安装完毕后,其实在树莓派上就可以用的。但在使用之前,根据需求,还应该做一些设置才好用。所以先不着急运行。
由于motion需要调用摄像头,我们就得知道摄像头的设备号。默认是 video0,如果用的USB摄像头,可能会是video1等别的序号。而motion默认调用的是video0,所以这一点得事先注意。
查看摄像头的设备号的代码是:
1 |
ls -al /dev/ | grep video |
比如我的设备号为:
记下 video0或video1,如果你没有这个,说明摄像头没有被识别,或者没有成果安装。最好也检查一下插线是否正确。
二、做一下配置:
配置是为了满足需求而做的,我的需求如下:
- 首先,由于是在终端中安装的,需要在终端关闭后依然能够运行;
- 其次,由于我需要在电脑或者手机上查看摄像头,就需要关闭该限制;
- 最后,希望它能够在树莓派重启后自动运行。
现在逐个解决:
首先,解决后台运行的问题,需要打开 motion daemon 守护进程,让它可以一直在后台运行,用以下代码:
1 |
sudo nano /etc/default/motion |
在里面找 start_motion_daemon ,把 no修改成yes:
1 |
start_motion_daemon=yes |
其次,解决局域网访问,要修改motion的配置文件,用以下代码:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
sudo vim /etc/motion/motion.conf #deamon off 改成 on 这一步是允许关闭终端后motion服务继续运行,是要配合刚才的代码 deamon on # Video device to be used for capturing (default /dev/video0) 选择用哪个摄像头进行录制,默认是video0,即CSI摄像头,我用到的USB摄像头,所以改为了video1 # for FreeBSD default is /dev/bktr0 videodevice /dev/video1 #设置分辨率,分辨率越低画面越流畅,640×480以及足够流畅 width 640 height 480 #关闭 localhost 的限制,允许局域网其他人访问,借助内网穿透可以实现外网访问 webcam_localhost off #由于默认配置是每秒截取一张图片,所以看起来会很卡顿,为了画面足够流畅,需要做以下设置: # Maximum framerate for stream streams (default: 1) 最大帧率,默认是1,即每秒1帧,这里修改为100,保证流畅 stream_maxrate 100 # Restrict stream connections to localhost only (default: on) 这里默认是指允许局域网串流,改为off则可以为全网串流 stream_localhost off |
其他诸如开启ipv6,运动监测等,根据需求进行配置。可以参看这个来学习:ConfigFileOptions < Motion < Foswiki (lavrsen.dk)
1 |
最后,加入启动项进行自启动:
编辑/etc/rc.local文件
1 |
sudo nano /etc/rc.local |
在文件中的 exit 0 之前添加需要执行的程序,注意要使用绝对路径,这里只需要输入 motion 即可:
保存退出,然后运行 motion:
1 |
sudo motion |
如果修改了配置文件,则要重启服务,可以使用代码:
1 |
sudo service motion restart |
实际效果如下面视频所示:
最后附上我自用的motion配置(注意,video1是我的配置,用的USB外置摄像头,如果你用的树莓派CSI摄像头,你可能得改为video0才能用)
