不存在用户定义的从"cv::Point"到"CvPoint"的适当转换

Question

 

Answer 1

函数参数类型不匹配

int get_distance(cv::Point p1,cv::Point p2)

将CvPoint转化成cv::Point。

typedef  struct  CvPoint
{
    int x;//图像中点的x坐标
    int y;//图像中点的y坐标
}CvPoint;

cv::Point p1;
cv::Point p2;
p1.x = RectContours[j][i].x;
p1.y = RectContours[j][i].y;
p2.x = RectContours[j][0].x;
p2.y = RectContours[j][0].y;
disTance = getDistance(p1,p2);
