小白樂園: 筆電攝像鏡頭運用+臉部偵測

本來要學學姊做的範例

因為學姊範例不知道是版本問題還是怎

不能複製貼上

所以又參考了估狗大神

我總共試做了7個

有兩個是失敗的

camera01 可攝影

camera02 失敗
使用VS內emgu套件無法使用

camera03 可攝影可截圖可存檔

camera04 失敗

camera05 照片可找臉

camera06 攝影截圖可找臉

camera07 可攝影同時找臉

重要步驟:

1.使用自己安裝的emgu(emgucv-windows-universal 3.0.0.2157) (之後再試著直接用visualstudio的套件,目前使用套件emguCV是失敗的)

2.更改專案名稱右鍵->屬性->建置->平台改為x64

3.增加參考(前三個那個

camera01 可攝影

程式碼:

因為是寒假寫的程式

現在匆匆整理出來還有很多步驟不足

之後再補充囉
