  • opencv4.5.0 +contrib编译流程

    (默认已完成安装visual studio 2019与python)

    1.下载opencv与opencv-contrib模块,国内镜像源:OpenCV/opencv_contrib国内快速下载 | 庐雪技术博客 (bzblog.online)

    2.下载cmake-gui版本 安装

    3.解压opencv-contrib与opencv到目标文件夹

    4.打开cmake,将解压opencv文件夹作为source,新建buildfile 作为编译文件夹

    5.出现错误:

     解决:

    一、ippicv_2020_win_intel64_20191018_general.zip下载失败
    进入opencv4.5.03rdpartyippicv目录
    将 ippicv.cmake 的https://raw.githubusercontent.com
    修改为:https://raw.staticdn.net

    二、opencv_videoio_ffmpeg_64.dll、opencv_videoio_ffmpeg.dll下载失败
    进入opencv4.5.0/3rdparty\ffmpeg目录
    将 ffmpeg.cmake 的https://raw.githubusercontent.com
    修改为:https://raw.staticdn.net

    参考:https://blog.csdn.net/valley2013/article/details/106911688/

    5.进行configure

    6.编译opencv-contrib:将OPENCV-ENABLE-NONFREE使能勾选,在下一格opencv extra module path设置contrib modulle文件夹 再勾选BUILD-opencv-world

    7.configure

    8.

    三、boostdesc_bgm.i相关文件下载失败
    进入opencv_contrib-3.4.2modulesxfeatures2dcmake目录
    将 download_boostdesc.cmake中的https://raw.githubusercontent.com
    修改为:https://raw.staticdn.net

    四、vgg_generated_120.i相关文件下载失败
    进入opencv_contrib-3.4.2modulesxfeatures2dcmake目录
    将 download_vgg.cmake中的https://raw.githubusercontent.com
    修改为:https://raw.staticdn.net

    五、face_landmark_model.dat下载失败
    修改.opencv_contrib-3.4.2modulesfaceCMakeLists.txt,
    将https://raw.githubusercontent.com
    修改为:https://raw.staticdn.net
    可能有时候会失败,多configure几次(如果一直下不了就不用管了,后面步骤也能进行)

    9.generate,将编译好的buildfile打开,找到install,打开opencv.sln(即open project)

    10.直接在上方生成处点击生成解决方案

    10.在CMakeTargets下面找到INSTALL,右键有仅用于项目->仅编译INSTALL  ()

    11.把刚生成的*Binfileinstallx64vc116in作为环境变量加进入(如果之前有OpenCV的就替换之前的,切记!)。

    12.VS配置:创建一个空白的c艹文件,在属性管理器中右键单击debug x64 创建新的项目属性表,

      a.增加编译头文件包含目录

      b.增加编译库文件包含路径

      

     增加库链接,打开install路径,找到x64/vc16/lib,将里面的lib复制名字过来

     验证:

    #include <opencv2/opencv.hpp>
    #include <opencv2/xfeatures2d.hpp>
    #include <iostream>
    
    using namespace cv;
    using namespace cv::xfeatures2d;
    using namespace std;
    
    int main(int argc, char** argv) {
    
        Mat test1 = imread("1.jpg");
        Mat atest1 = imread("2.jpg");
        if (test1.empty())
        {
            cout << "error!" << endl;
        }
        imshow("test1 image", test1);
        imshow("atest1 image", atest1);
    
        auto detector = SIFT::create();
        vector<KeyPoint> keypoints_test1, keypoints_atest1;
        Mat descriptor_test1, descriptor_atest1;
        detector->detectAndCompute(test1, Mat(), keypoints_test1, descriptor_test1);
        detector->detectAndCompute(atest1, Mat(), keypoints_atest1, descriptor_atest1);
    
        Ptr<FlannBasedMatcher> matcher = FlannBasedMatcher::create();
        vector<DMatch> matches;
        matcher->match(descriptor_test1, descriptor_atest1, matches);
        Mat dst;
        drawMatches(test1, keypoints_test1, atest1, keypoints_atest1, matches, dst);
        imshow("match-demo", dst);
    
    
        waitKey(0);
        return 0;
    }
            

    注意:1,2.jpg需要自己的图片路径

    最终效果:
