Question

我从github repo

合并了opencv和opencv-contrib

我的操作系统是Windows 8.1

请按以下步骤操作：

1.下载Github Repo。

opencv (Itseez/opencv)
opencv_contrib (Itseez/opencv_contrib)

D:\opencv_merge\opencv-master
D:\opencv_merge\opencv_contrib-master

2。下载并安装CMake Lastest Version（当前版本为3.5.2）

3。 CMake Generate

(1)
Open CMake GUI 
setting path
source code: D:\opencv_merge\opencv-master
build the binaries: D:\opencv_merge\opencv-master\build
(2)
press 'Configure' 
wait for 'Configuring done'

watch output

 Java:
    ant:                         C:/apache-ant-1.9.7/bin/ant.bat (ver 1.9.7)
    JNI:                         C:/Program Files/Java/jdk1.8.0_91/include C:/Program Files/Java/jdk1.8.0_91/include/win32 C:/Program Files/Java/jdk1.8.0_91/include
    Java wrappers:               YES
    Java tests:                  YES

（3）设置OPENCV_EXTRA_MODULES_PATH

D:/opencv_merge/opencv_contrib-master/modules

press 'Configure' 
watch output double check again

（4）生成

4。打开OpenCV.sln

在'Solution Explorer' CMakeTargets-->Install -->Right Click -->Build

5。获取opencv-310.jar和opencv_java310.dll

(D:\opencv_merge\opencv-master\build\install\java)

6。 Netbeans设置

(1) add Opencv Library (add opencv-310.jar to Library)
(2) VM options: -Djava.library.path=D:\opencv_merge\opencv-master\build\install\java

7。运行项目

8。写一些代码：

public static void main(String[] args) {
System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
.....
FeatureDetector orbDetector = FeatureDetector.create(FeatureDetector.ORB);
.....
FeatureDetector siftDetector = FeatureDetector.create(FeatureDetector.SIFT);
.....
FeatureDetector surfDetector = FeatureDetector.create(FeatureDetector.SURF);
}

9。运行项目和测试

ORB检测器可以执行（当然）

但是SIFT和SURF探测器不能

我看到这种情绪后做了一些修改：（SURF and SIFT algorithms doesn't work in OpenCV 3.0 Java）

我根据上述网址编辑'D:\opencv_merge\opencv-master\modules\features2d\misc\java\src\cpp\features2d_manual.hpp'，然后开始第二步。

然而，在第五步中，在java文件夹（D:\opencv_merge\opencv-master\build\install\java）中找不到'opencv_java310.dll' 我尝试重复相同的步骤至少5次，但仍然没有'opencv_java310.dll'

原因似乎是我手动更改了'features2d_manual.hpp'

我整天都在外面:(

谁能帮我解决这个问题

谢谢你们

Answer 1

猜测您的问题是您需要在手动修改features2d_manual.hpp后重新编译。这对我有用。

您可以在“SURF and SIFT algorithms doesn't work in OpenCV 3.0 Java”

中查看我的答案

SURF和SIFT算法在Open CV 3.0 Java中不起作用
