Exporting a template parameter file

Goal

In this tutorial you will learn how to

• create a simple parameter file template.

#include <opencv2/core.hpp>
#include <opencv2/xstereo.hpp>

using namespace cv;
using namespace std;

int main(int argc, char* argv[])
{
    Ptr<stereo::QuasiDenseStereo> stereo =  stereo::QuasiDenseStereo::create(cv::Size(5,5));

    std::string parameterFileLocation = "./parameters.yaml";
    if (argc > 1)
        parameterFileLocation = argv[1];
    stereo->saveParameters(parameterFileLocation);

    return 0;
}

Explanation:

The class supports loading configuration parameters from a .yaml file using the method loadParameters(). This is very useful for fine-tuning the class’ parameters on the fly. To extract a template of this parameter file you run the following code.

We create an instance of a QuasiDenseStereo object. Not specifying the second argument of the constructor, makes the object to load default parameters.

Ptr<stereo::QuasiDenseStereo> stereo =  stereo::QuasiDenseStereo::create(cv::Size(5,5));

By calling the method saveParameters(), we store the template file to the location specified by parameterFileLocation

std::string parameterFileLocation = "./parameters.yaml";
if (argc > 1)
    parameterFileLocation = argv[1];
stereo->saveParameters(parameterFileLocation);
