1 连接USB摄像头模块(FA-CAM202)
FA-CAM202是一款200万像素的USB摄像头模块,连接开发板和摄像头,然后上电启动系统,连接网络,以root用户登录终端并编译运行mjpg-streamer:
$ cd /root/C/mjpg-streamer $ make $ ./start.sh
请自行修改start.sh, 确保使用正确的/dev/videoX节点, 下列命令可以用来确定摄像头的video节点:
$ apt-get install v4l-utils $ v4l2-ctl -d /dev/video0 -D # fa-cam202有2个型号 Driver Info (not using libv4l2): Driver name : uvcvideo Card type : HC 3358+2100: HC 3358+2100 / USB 2.0 Camera: USB 2.0 Camera Bus info : usb-1c1b000.usb-1 ...
上述信息表示/dev/video0是摄像头的设备节点。mjpg-streamer是一个开源的网络视频流服务器,在板子上成功运行mjpg-streamer后会打印下列信息:
$ ./start.sh i: Using V4L2 device.: /dev/video0 i: Desired Resolution: 1280 x 720 i: Frames Per Second.: 30 i: Format............: YUV i: JPEG Quality......: 90 o: www-folder-path...: ./www/ o: HTTP TCP port.....: 8080 o: username:password.: disabled o: commands..........: enabled
start.sh脚本里执行了下列2个命令:
export LD_LIBRARY_PATH="$(pwd)" ./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -y 1 -r 1280x720 -f 30 -q 90 -n -fb 0" -o "./output_http.so -w ./www"
mjpg_streamer相关参数的含义如下:
-i: 选择输入插件,input_uvc.so表示从摄像头采集数据;
-o: 选择输出插件,output_http.so表示使用http协议传输数据;
-d: 输入插件的子参数,指定摄像头设备节点;
-y: 输入插件的子参数,指定摄像头采集数据的格式,1:yuyv, 2:yvyu, 3:uyvy 4:vyuy,如果不使用-y参数,则表示采集MJPEG格式;
-r: 输入插件的子参数,指定摄像头采集分辨率;
-f: 输入插件的子参数,指定想使用的摄像头采集fps,具体是否支持依赖于驱动;
-q: 输入插件的子参数,指定libjpeg软编码的图像质量;
-n: 输入插件的子参数, 禁止dynctrls功能;
-fb: 输入插件的子参数, 指定是否在/dev/fbX上显示采集的图像;
-w: 输出插件的子参数, 指定包含网页的目录;
成功运行start.sh脚本后,假设开发板的IP地址为192.168.1.230,在PC的浏览器中输入 192.168.1.230:8080 就能浏览摄像头采集的画面了,效果如下:
2 查看CPU温度和频率
命令行查看:
$ cpu_freq Aavailable frequency(KHz): 480000 624000 816000 1008000 Current frequency(KHz): CPU0 online=1 temp=26548C governor=ondemand freq=624000KHz CPU1 online=1 temp=26548C governor=ondemand freq=624000KHz CPU2 online=1 temp=26548C governor=ondemand freq=624000KHz CPU3 online=1 temp=26548C governor=ondemand freq=624000KHz
上述信息表示当前有4个CPU核在线, 温度均约为26.5摄氏度, 运行的策略均为根据需求来决定运行频率, 当前的运行频率均为624MHz,设置频率的命令如下:
$ cpu_freq -s 1008000 Aavailable frequency(KHz): 480000 624000 816000 1008000 Current frequency(KHz): CPU0 online=1 temp=36702C governor=userspace freq=1008000KHz CPU1 online=1 temp=36702C governor=userspace freq=1008000KHz CPU2 online=1 temp=36702C governor=userspace freq=1008000KHz CPU3 online=1 temp=36702C governor=userspace freq=1008000KHz
上述命令将4个CPU核的频率设置为1008MHz。
3 运行Qt示例程序
执行以下命令:
$ sudo /opt/QtE-Demo/run.sh
运行结果如下,这是一个开源的QtDemo:
4 Docker在armhf系统下的安装与使用
4.1 安装 Docker
执行下列命令:
sudo apt-get update sudo apt-get install docker.io
4.2 测试 Docker
执行下列命令运行一个简单的docker image:
git clone https://github.com/friendlyarm/debian-jessie-arm-docker cd debian-jessie-arm-docker ./rebuild-image.sh ./run.sh
