我正在尝试haarcascade_frontalface_alt.xml使用以下代码从 Android 资产加载文件：

File file = loadCascadeClassifierFile(context);
    if (file.exists()) {
        return new CvHaarClassifierCascade(cvLoad(file.getAbsolutePath());
    }else {
        throw new FileNotFoundException("File not found.");
    }

loadCascadeClassifierFile 完成它的工作并返回一个包含 xml 的文件，但它在

CvHaarClassifierCascade(cvLoad(file.getAbsolutePath());

例外是：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.myapp.facerecognition.facerecognition/com.myapp.facerecognition.facerecognition.activity.MainActivity}: java.lang.RuntimeException: /home/saudet/projects/bytedeco/javacpp-presets/opencv/cppbuild/android-arm/opencv-2.4.11/modules/core/src/persistence.cpp:5113: error: (-204) Could not find the/an object in file storage in function void* cvLoad(char const*, CvMemStorage*, char const*, char const**)

        at dalvik.system.NativeStart.main(Native Method)

我已经在这个问题上停留了一段时间。有人解决过这个问题吗？

也许下面的代码可以工作：

File file = loadCascadeClassifierFile(context);
if (file.exists()) {
    CvHaarClassifierCascade* classifer = (CvHaarClassifierCascade*)cvLoad(file.getAbsolutePath();
    return *classifer;
}else {
    throw new FileNotFoundException("File not found.");
}
