❷ 易語言怎麼做視頻監控求源碼！QAQ
首先，易語言高！成千上萬的源碼可以借鑒！
其次夠底層，直接嵌入匯編！用上黑月插件，編譯夠小！
易語言的獨特模塊，拿來就用！
_
破解，病毒，游戲輔助，基本都是在反編譯，掌握了程序基本情況之後，在寫程序！！
寫內存，讀內存，進程注入，這些技術在其他編程語言實現你的看各種文檔！ 而易語言，各種注入模塊，驅動讀寫內存，都是現成的！
而其他語言，如C語言，你寫的時候，很多時間，都是在了解c的各種庫。本來你只想吃饅頭，用c你就得了解包頭的烹飪方法！如果，你還需要互動的界面的話......成本太高了！
易語言很多時候其實只是負責UI，很多動態庫都是其他語言編寫的，易語言負責調用整合！
可以說，易語言，在開發小程序，有天然的優勢！

❺ 最近，想用MFC編個對話框，能夠實時顯示攝像頭捕捉的鏡頭！誰有源代碼，能否發我一份吧！感激涕零啊……
現在在vc上採集視頻常用的方法有三：vfw，directshow，opencv
你是要進行圖像處理的話推薦opencv（具體參考：於仕琪，opencv教程基礎篇中的例3-6，稍作修改，估計就能用於你的工程）
下面貼出我自己編的一個小工程：如有疑問，E-mail：[email protected]
進行opencv的預備操作你要看那本書和逛opencv中文網
如有問題可以和我討論（我也是菜鳥，剛為解決了這個問題竊喜不已）。
1.新建mfc對話框工程，在其中添加一個picture控制項，除了ID以外什麼都不用改
2.在對話框頭文件（沒有Dlg那個）中添加（最好是在「#include "resource.h" // main symbols之後」）：
#include "cxcore.h"
#include "cvcam.h"
#include "windows.h"
#include "cv.h"
#include "highgui.h"
3.在工程-》設置-》選擇所有配置-》link（連接）-》對象/庫模塊-》中添加：
kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib cxcore.lib cv.lib ml.lib cvaux.lib highgui.lib cvcam.lib
4.在需要觸發攝像頭顯示的地方添加：
void CVideomfcDlg::OnButton1()
{
// TODO: Add your control notification handler code here
int ncams = cvcamGetCamerasCount( );//返回可以訪問的攝像頭數目
HWND MyWin=::GetDlgItem(m_hWnd,IDC_VIDEO); //獲得控制項句柄（IDC_VIDEO就是圖片控制項）
cvcamSetProperty(0, CVCAM_PROP_ENABLE, CVCAMTRUE); //選擇第一個攝像頭
int width=240;
int height=240;
cvcamSetProperty(0,CVCAM_PROP_WINDOW, &MyWin); // Selects a window for
cvcamSetProperty(0,CVCAM_RNDWIDTH, &width);
cvcamSetProperty(0,CVCAM_RNDHEIGHT, &height);
cvcamSetProperty(0, CVCAM_PROP_CALLBACK, callback1);
//回調函數將處理每一幀
cvcamInit( );
cvcamStart( );
}
5.改變顯示的圖像序列大小，在窗口屬性設定了以後，添加如下代碼：
int width=320; //這個就是需要顯示的窗口大小
int height=240; //根據自己需要選擇
cvcamSetProperty(0,CVCAM_RNDWIDTH, &width);
cvcamSetProperty(0,CVCAM_RNDHEIGHT, &height);
6.在對話框類中添加callback成員函數（注意，在添加函數的時候，一定要選擇static，不選的話你就自己郁悶去吧，反正我是為了這個郁悶了2個禮拜）
void CVideomfcDlg::callback1(IplImage *image)
{
IplImage* image1 = image;
int i,j;
assert (image);
//獲取當前系統時間
SYSTEMTIME st2=;
GetLocalTime(&st2);
char sss[18]=; //這個是用來存儲所要保存的圖片名的，用的是一個笨辦法，先定義，再修改其中的數組值。
sss[7]=st2.wHour/10+48; //獲取系統當前小時
sss[8]=st2.wHour%10+48;
sss[9]=st2.wMinute/10+48; //獲取系統當前分鍾
sss[10]=st2.wMinute%10+48;
sss[11]=st2.wSecond/10+48; //獲取系統當前秒
sss[12]=st2.wSecond%10+48;
cvSaveImage(sss,image1); //使用系統當前時間為名稱（XXXXXX.jpg）存儲圖片
}
ps：你還需要在c盤根目錄下建立一個叫1的文件夾保存圖片。
祝你成功！
❻ android 實時監控硬體攝像頭如何實現 求個源碼
實時監控還是比較厲害的，後台拍攝記錄？不懂是個什麼意思，程序調用攝像頭拍照還是比較簡單的。
❼ 求「VC++實現的支持攝像頭和圖像的人臉識別系統」源碼和報告
實現支技攝像頭和八圖像人臉識別二維碼掃描器實現夢想的聲音好大。
❽ 求 在網頁中打開查看區域網內的攝像頭的監控畫面 的例子（源碼），請不吝賜教，在下感激不盡。
這是正解。。。。
那個監視系統要兼容你用網頁打開的操作。
如果不兼容，打死我也沒辦法，你用的那個軟體，如果支持這種調用，應該會寫出來。並且會寫出詳細調用方法、提供源碼或直接提供一個網頁。
你的監視器是什麼埠？網路攝像頭么。。
廠商不是傻X，有網頁調用的方法，絕對會立刻發布。。。
lz，偶愛莫能助。。。。
