no opencv_imgproc343 in java.library.path

aaronwong1989 commented 6 years ago

我执行java命令时增加的参数 -Djava.library.path=D:/app/opencv/java/x64 我的dll文件都这这个目录

  public static void main(String[] args) {
    SpringApplication.run(BlindWatermarkApplication.class, args);
    System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    loadOpenCvTest();
    Loader.load(opencv_core.class);
  }

  public static void loadOpenCvTest() {
    Mat mat = Mat.eye(3, 3, CvType.CV_8UC1);
    logger.info("opencv load success ! \n" + mat.dump());
  }

这是我的java代码，第一种方式的测试可以通过，但是运行到load方法就报错，请问时什么原因？

1.尝试将依赖改为org.bytedeco:javacv-platform:1.4.3 2.尝试增加参数-Djavacpp.platform.dependencies=true 3.参考https://github.com/bytedeco/javacpp-presets/wiki/Debugging-UnsatisfiedLinkError-on-Windows

1.依赖改为：

<dependency>
  <groupId>org.bytedeco</groupId>
  <artifactId>javacv-platform</artifactId>
  <version>1.4.2</version>
</dependency>

2.Mat 引用 opencv_core 下的 Mat 3.使用 javacv 不需要再 loadLibrary
