OpenCV + OpenWRT 无线摄像头监控和图像处理
本帖最后由 hosea1008 于

诚然，可以使用OpenCV的linux版本把该功能做到嵌入式设备当中，然而当处理复杂的时候就需要在服务器平台上进行图像处理运算，本文尝试简单实现这一功能
【OpenWRT】
OpenWRT是广泛使用的开源路由器操作系统，因为开源所以强大。
手头有一台MW151路由，据悉该路由与TP-Link 703n的区别只是USB口，改装升级内存和flash，刷上703n的OpenWRT固件，一台适宜开发的设备诞生了。
【步骤：路由】
路由器上的原材料：
mjpeg-streamer软件
免驱摄像头（笔者使用的是某宝上淘来的东芝笔记本拆机摄像头）
首先要实现图像传输需要在路由上挂载USB摄像头，本文挂出来的路由固件已经有具有相应组件（kmod-video-core和kmod-video-uvc）。
1.安装mjpeg-streamer讲软件解压，把其中的www目录放到路由器的www目录下，改名为camwww，向路由器上传文件可以用WinSCP，重启路由

2.插好摄像头开机，启动mjpeg-streamer，ssh登陆路由（可以用Putty软件ssh登录）输入以下命令
mjpg_streamer -i &input_uvc.so&&-d /dev/video0& -o &output_http.so -p 8080 -w /www/camwww&复制代码
8080指视频流使用端口，可以自定义，其余选项为默认分辨率640x480，30fps

用户可以根据自己的需求自定义，例如
mjpg_streamer -i &input_uvc.so -f 15 -r 320*240 -d /dev/video0& -o &output_http.so -p 8080 -w /www/camwww&复制代码
表示分辨率320x240，15fps
这时候可以看到摄像头的LED被点亮，结束操作时在SSH窗口中按Ctrl+C键可退出mjpg-streamer

22:40 上传
此时用浏览器（建议用火狐）连接路由器打开以下地址，可以查看摄像头的实时图像
http://192.168.10.1:8080/?action=stream复制代码
至此，OpenWRT已经实现挂载摄像头进行无线监控。
【步骤：OpenCV】
电脑是已经安装好Visual Studio 2013并配置好OpenCV 2.4.10
要用OpenCV对路由器传输的实时图像进行处理，只需要让程序从网页获取图像，在while循环里不断把采集的图像转换成Mat矩阵（新版本的OpenCV正在逐步淘汰IplImage结构体）既可，令人欣喜的是，OpenCV里的VideoCapture类本身就能从网页获取图像，因此带来了极大的方便，具体如下：
#include &opencv2/highgui/highgui.hpp&
#include &opencv2/imgproc/imgproc.hpp&
#include &iostream&
#include &stdio.h&
//头文件
/** @function main */
int main(int argc, char** argv)
{
& && &&&M
& && &&&cv::VideoC
& && &&&const string address = &http://192.168.10.1:8080/?action=stream?dummy=param.mjpg&;
& && &&&if (!vcap.open(address))
& && &&&{
& && && && && & cout && &Error opening video stream& &&
& && && && && & return -1;
& && &&&}
& && &&&cout && &Stream opened& &&
& && &&&while (1)
& && &&&{
& && && && && &
& && && && && & vcap &&
& && && && && & // your code here
& && && && && & /// Show your results
& && && && && & namedWindow(&Cam&, CV_WINDOW_AUTOSIZE);
& && && && && & imshow(&Cam&, src);
& && && && && & if (waitKey(2) == 27)
& && && && && && && && &
& && && && && &&&// Press &Esc& to exit
& && &&&}
& && &&&return 0;
}复制代码
上文中如果address直接等于浏览器地址栏中输入的地址，将不能获取图像，一个解释是，需要让程序知道视频流是jpeg类型，因此“伪造”了一个jpeg文件名
下图是修改OpenCV官网的一个demo，亲测在路由上获取图像可行（分别从笔记本摄像头和路由器挂载的无线摄像头）

大哥呀，，，
在这个论坛也看到你了，
你主要在哪个论坛啊，我想请教几个问题。
问题已经解决了，
多谢楼主~\(≧▽≦)/~啦啦啦
很厉害啊，这样可以实现一些智能监控了
大哥呀，，，
在这个论坛也看到你了，
你主要在哪个论坛啊，我想请教几个问题。
然后找了你好久，，，
但现在只剩下一个问题了，
就是为什么用直接用浏览器 action=stream 看视频的帧数可以30左右
但是用上面的代码之后，变得有些卡顿呢
真的棒 想学习
收藏下！收藏下！收藏下！

支持OpenWrt的摄像头选购经验
关于OpenWrt下最经典的摄像头方案，当属VIMICRO中星微ZC0301PL方案，淘宝10元左右一个，一般都是拆机货，比较旧，没有外壳也没有牌子，但几乎都能用。网络上的教程，也大多都是基于中星微的301方案。
这种价钱的摄像头效果都不怎么样，特别是在弱光下很模糊。
现在一些主流的摄像头都是所谓“高清”或者720P的，价格一般几十元或者更高。虽然贵一些，但是确实清晰很多，在较弱光线下，也能提供尚可的清晰度。但是如果你是想把摄像头接到openWRT的路由器上用，就要注意了，因为有一定可能性会杯具。原因如下：
主流的摄像头有两种输出格式：mjpg和YUV格式，当然还有RGB24的，这里暂不讨论。
如果摄像头支持mjpg格式输出，远程摄像头软件mjpg-streamer只需要将得到jpeg格式的图片转发到HTTP服务器就可以了。但如果摄像头不支持mjpg格式输出，仅支持YUV格式，那mjpg-streamer需要将原始图片压缩成jpeg格式，这个过程需要消耗大量CPU资源。前几年电脑硬件性能不强，所以一般摄像头都支持mjpg格式输出，现在的电脑性能都很强了，所以大部分摄像头即使不支持mjpg格式输出，在电脑上用也没啥区别，但在路由器上用就另当别论了。用用YUV模式在较高分辨率下（例如640x480）可能会非常卡或者延迟。
那么，如果我们想买一个效果比中星微301方案好，但是又保证在OpenWrt下可以正常使用的摄像头，该如何选择呢？
OpenWRT官方网站给出了一个官方的指引：
如果想买gspca摄像头（即有驱摄像头），可以看这里：
但是gspca都是比较旧的东西了，现在的基本上是UVC摄像头（即免驱摄像头），所以一般情况下请看这个列表：
理论上大部分UVC摄像头都是支持的，但我们看到，即使是官方的列表，UVC摄像头也很多有些问题，而且如果UVC摄像头不支持mjpg输出，那分辨率就算320x240，也有不小的延迟。怎么看UVC摄像头是否支持mjpg输出呢？还是要看主控芯片...现在的摄像头品牌太多了，而且大部分都不会标明自己的主控芯片，所以很难根据主控芯片去买。不过基本上市面上低于50元的全新摄像头，都不支持mjpg输出（主控芯片的价格问题）。
如果根据官方的UVC列表来购买，一定要买右边是绿色勾的，而且旁边没有数字的才行，右边的数字是表示有某些已知的问题。我们也可以去官方网站查看摄像头的参数，不过只有奥尼（http://www.aoni.cc/）等少数厂家会标明该参数。另外，还可以通过网上的测评文章得知摄像头的芯片，
列表里面大多数国内都买不到，我把列表中几个方便买到的而且价格不太高的摄像头（200元以内微软和罗技的）发出来，给大家做个参考。总比买几个几十块的摄像头，才发现都不适合好些。

网友使用感受
下面是OpenWrt中文网（）网友lancerz使用百脑通-D881HD720P摄像头，经过703n（32M未改动）的mjpg-streamer发送的图片。在谷歌浏览器看到的效果还可以，注意D881有一个是旧版的，不是720P，不要贪便宜买那个。
测试640x480@25pfs，CPU用25%左右。pfs，CPU用30%左右。以下是pfs运行了1个小时后的系统状态：
稳定性问题：fps，分别运行了1个小时和2个小时，之后死机，putty也连不上。在640x480@30fps，运行了4个小时都没问题。查看资源，CPU利用率都差不多，但是720p的剩余内存只有2M多点，480p有接近7M，不知道是不是和内存有关。
如果希望将监控画面自动发送到邮箱，可以使用motion，详见：

驱动没有安装吧？
看你后面给出的信息里
uvcvideo: Found UVC 1.00 device USB 2.0 Camera (0c45:62f0)
opkg install kmod-video-uvc
应该能解决问题
kmod包与设备不兼容
找对应版本的kmod包
& & 斑竹啊，既然有提示uvcvideo：之类的，那说明kmod-video-uvc已经装好了。
LZ，对于支持UVC的摄像头，记得还要装下面两个包：
kmod-i2c-core
kmod-input-core
& & 相关包都是论坛下载的,不存在KMOD内核不兼容的问题
