C++SDK配置与演示

下载C++ SDK开发包，下载地址

https://gitee.com/opencv_ai/opencv_workflow

解压缩开发包

打开VS2022，配置包含目录

D:\vcworkspaces\oemts_workflow_engine_lib\include\oemts

配置库目录

D:\vcworkspaces\oemts_workflow_engine_lib\lib

直接编译提供的示例代码，然后把oemts_workflow_engine.dll 文件放到项目生成目录下即可运行exe，运行结果如下：

完整的示例代码如下：

特别提醒：

请先配置好OpenCV4.10 C++依赖。

卡尺测量演示

首先配置好开发环境，OpenCV工作流最新版本依赖于OpenCV4.10，所以先配置好OpenCV4.10 C++ 开发环境，然后配置好OpenCV工作流。首先加载工作流配置文件

// load opencv workflow sdk
std::shared_ptr<QTongCoreCVWorkFlow> engine(new QTongCoreCVWorkFlow());
bool succ = engine->initWorkFlow("D:/python/opencv_workflow/qtong_caliper.vm", 
"ba8e9ea82fb37f1722ad2d9f4962e7e4");
if (!succ) {
  std::cout << "Could not load workflow file here..." << std::endl;
  return -1;
}

然后加载测试图像并显示

//  image view
cv::Mat frame = cv::imread("D:/images/vm_test/caliper_test.png");
cv::imshow("OpenCV学堂-卡尺演示", frame);

调用卡尺测量SDK实现卡尺测量

// measure with caliper sdk
cv::Mat result;
cv::Vec4i data(291, 254, 118, -1);
engine->run_measure(frame, result, data);

调用查询SDK获取测量结果

// query measure circle information
cv::Vec3i cinfo = engine->getMeasureCircleInfo();
std::cout << "圆心 X: " << cinfo[0] <<" 圆心 Y: "<<cinfo[1]<< std::endl;
std::cout << "圆半径: " << cinfo[2] << std::endl;

完整的源代码如下：

#include "main_workflow.h"
#include <iostream>
#include <fstream>"
int main(int argc, char** argv) {
// load opencv workflow sdk
  std::shared_ptr<QTongCoreCVWorkFlow> engine(new QTongCoreCVWorkFlow());
  bool succ = engine->initWorkFlow("D:/python/opencv_workflow/qtong_caliper.vm", 
                      "ba8e9ea82fb37f1722ad2d9f4962e7e4");
  if (!succ) {
    std::cout << "Could not load workflow file here..." << std::endl;
    return -1;
  }
  // image view
  cv::Mat frame = cv::imread("D:/images/vm_test/caliper_test.png");
  cv::imshow("OpenCV学堂-卡尺演示", frame);
  // measure with caliper sdk
  cv::Mat result;
  cv::Vec4i data(291, 254, 118, -1);
  engine->run_measure(frame, result, data);
  // query measure circle information
  cv::Vec3i cinfo = engine->getMeasureCircleInfo();
  std::cout << "圆心 X: " << cinfo[0] <<" 圆心 Y: "<<cinfo[1]<< std::endl;
  std::cout << "圆半径: " << cinfo[2] << std::endl;
  cv::imshow("OpenCV学堂-卡尺效果", result);
  cv::waitKey(0);
  cv::destroyAllWindows();
  return 0;
}

运行结果如下：
