## 安裝OpenCV

cd opencv-4.9.0zip
mkdir build && cd build

## Springboot 整合

Lib 放置

JDK -VM設置

-Djava.library.path=/Users/gn715364/Documents/server/opencv-4.9.0/lib

Gradle Jar設置
build.gradle

dependencies {
    implementation fileTree(dir: 'libs',includes: ['*.jar'])
    ...
}

測試程式碼

static {
    try {
        logger.info("Start headless mode...");
        System.setProperty("java.awt.headless", "true");
        logger.info("Path：{}", System.getProperty("java.library.path"));
        logger.info("Add OpenCV lib...");
        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
        logger.info("load success");
    } catch (Exception e) {
        e.printStackTrace();
    }
}

...
...
    
Resource resource = new ClassPathResource("xml/haarcascade_frontalface_alt.xml");

if(resource.exists()) {
    CascadeClassifier faceDetector = new CascadeClassifier();
    faceDetector.load(resource.getURI().getPath());

    String imgPath = "/Users/gn715364/Documents/server/opencv-4.9.0/image/group1.jpg";
    Mat image = Imgcodecs.imread(imgPath);
    if (image.empty()) {
        throw new RuntimeException("圖片內存為空");
    }

    MatOfRect face = new MatOfRect();
    faceDetector.detectMultiScale(image, face);
    Rect[] rects = face.toArray();
    System.out.println("識別人臉個數： " + rects.length);

}

注意：以下兩個套件一定要拿掉，不然OpenCV無法連結

spring-boot-devtools
springloaded
