无法加载在necessitas opencv的库 [英] Can not load Opencv libraries in necessitas

问题描述

我尝试用相机使用OpenCV的一个necessitas项目。我有这样的.pro文件

I try to use the camera in a necessitas project using OpenCV. I have this on the .pro file

INCLUDEPATH += C:/OpenCV-2.3.1-android-bin/OpenCV-2.3.1/include \
                C:/OpenCV-2.3.1-android-bin/OpenCV-2.3.1/modules

LIBS += C:/OpenCV-2.3.1-android-bin/OpenCV-2.3.1/libs/armeabi/libnative_camera_r2.2.2.so \
        C:/OpenCV-2.3.1-android-bin/OpenCV-2.3.1/libs/armeabi/libnative_camera_r2.3.3.so \
        C:/OpenCV-2.3.1-android-bin/OpenCV-2.3.1/libs/armeabi/libopencv_androidcamera.a \
        C:/OpenCV-2.3.1-android-bin/OpenCV-2.3.1/libs/armeabi/libopencv_calib3d.a \ ...

和我所说的相机时，我preSS一个按钮这样的：

and I call the camera when I press a button with this:

void MainWindow::on_foto_clicked()
{
    CvCapture * camera = cvCreateCameraCapture( 0 );
    IplImage * image = cvQueryFrame( camera );

    cvReleaseCapture( &camera );
}

当我运行它，它试图将设备，三星Galaxy GIO的Andr​​oid 2.3.4上运行，我得到这样的：

When I run it and It tries to run on the device, a samsung galaxy gio with Android 2.3.4, I get this:

W/System.err(17481): Caused by: java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1963]:    94 could not load needed library 'libnative_camera_r2.2.2.so' for 'libGeopei.so' (load_library[1105]: Library 'libnative_camera_r2.2.2.so' not found)

我错过加载任何图书馆或包括哪些内容？

Am I missing to load any library or include?

在此先感谢

推荐答案

您将需要手动复制 libnative_camera_r2.2.2.so 到 /安卓/库/ armeabi-V7A 目录。

You will need to manually copy libnative_camera_r2.2.2.so to /android/libs/armeabi-v7a directory.

然后，修改 QtActivity.java 文件，以便在启动时手动加载库：

Then, modify the QtActivity.java file in order to load the libs manually at startup:

String appPath = getApplication().getApplicationContext().getFilesDir().getAbsolutePath(); 

//application path
System.load(appPath+"/../lib/libnative_camera_r2.3.3.so");
System.load(appPath+"/../lib/libopencv_java.so");
