注解

必须确保您已经成功安装了 RMVL

如果你不熟悉 CMake，请移步到 CMake 教程

详细步骤

1. 创建项目

创建新的文件夹：rmvl_deploy_test，将其链接至 RMVL

mkdir rmvl_deploy_test build
cd rmvl_deploy_test
touch main.cpp CMakeLists.txt

2. 编写测试文件

2.1 编写 main.cpp

将以下内容写至 main.cpp 中

#include <opencv2/imgproc.hpp>
#include <opencv2/highgui.hpp>
 
#include <rmvl/detector.hpp>
 
using namespace std;
using namespace cv;
 
int main(int argc, char *argv[])
{
    Mat src = Mat::zeros(Size(1280, 1024), CV_8UC3);
 
    line(src, Point(450, 380), Point(440, 470), Scalar(0, 0, 255), 18);
    line(src, Point(650, 400), Point(640, 490), Scalar(0, 0, 255), 18);
    line(src, Point(850, 370), Point(870, 460), Scalar(0, 0, 255), 18);
 
    detect_ptr detector = ArmorDetector::make_detector();
    vector<group_ptr> groups;
 
    detector->detect(groups, src, RED, GyroData(), getTickCount());
    auto p_combos = detector.combos;
 
    INFO_("size of armors = %ld", p_combos.size());
    for (auto &p_combo : p_combos)
    {
        auto corners = p_combo->getCorners();
        line(src, corners[0], corners[2], Scalar(0, 255, 0), 2);
        line(src, corners[1], corners[3], Scalar(0, 255, 0), 2);
    }
 
    namedWindow("rmvl_deploy_test: src", WINDOW_NORMAL);
    resizeWindow("rmvl_deploy_test: src", Size(640, 512));
    imshow("rmvl_deploy_test: src", src);
 
    HIGHLIGHT_("RMVL build Successfully!\n\n\t\t-------- "
               "press any key to exit this program. --------\n");
    waitKey(0);
 
    return 0;
}

2.2 编写 CMakeLists.txt

将以下内容写至 CMakeLists.txt 中

cmake_minimum_required(VERSION 3.19)
project(rmvl_deploy)
find_package(RMVL REQUIRED)
add_executable(demo main.cpp)
target_include_directories(
    demo
    PUBLIC ${RMVL_INCLUDE_DIRS}
)
target_link_libraries(
    demo
    ${RMVL_LIBS}
)

3. 构建项目

在 rmvl_deploy_test 的顶层文件夹中打开终端，输入以下命令

cd build
cmake ..
make

4. 运行

继续输入以下命令

./demo
