c++ - 如何将 boost::geometry::distance 与 opencv cv::Point 一起使用？

Question

typedef boost::geometry::model::d2::point_xy<double> boostPoint;

如何在不转换为 boostPoint 的情况下将 boost::geometry::distance 与 opencv cv::Point 一起使用？

double EuclideanDistance(const cv::Point2d &pt1, const cv::Point2d &pt2)
{
    boostPoint boostPt1(pt1.x, pt1.y);
    boostPoint boostPt2(pt2.x, pt2.y);

    double distance= boost::geometry::distance(boostPt1, boostPt2);

    return distance;
}

更新:

我试过这段代码，但它向 x 提示 error: ‘x’ has not been declared

BOOST_GEOMETRY_REGISTER_POINT_2D(cv::Point2d, double, boost::geometry::cs::cartesian, x, y)

确保包含必要的 header ，如 doc 所示:

#include <boost/geometry/geometries/register/point.hpp>
