哈囉你好嗎隨便 week12

1準備工作


安裝 OpenCV 和設定 CodeBlocks

1. 安裝 OpenCV

  1. 安裝過程中勾選 Add PATH (第二個選項)。
  2. 將 OpenCV 安裝在預設目錄。

2. 設定 CodeBlocks

  1. 打開 CodeBlocks，進入 Settings -> Compiler。
  2. 重啟 CodeBlocks。
  3. 在 View -> Start Page 找到原本的檔案。
  4. 在 Settings -> Compiler -> Search directories 添加以下目錄：
    • Compiler: C:\OpenCV2.1\include
    • Linker: C:\OpenCV2.1\lib
  5. 在 Linker settings 中添加以下項目：
    • cv210
    • cxcore210
    • highgui210


freeglut複製 32搞定
