【OpenCV学习】基本数据结构-优快云博客

本文通过示例介绍了CvPoint、CvPoint2D32f等数据类型的定义与转换方法，并展示了如何使用这些类型进行二维及三维坐标点的创建与输出。

#include <cv.h>
#include <stdio.h>
#include <stdlib.h>

int main()
{
CvPoint Point1=cvPoint(300,200);

CvPoint2D32f Point2 = cvPoint2D32f(200.0,240.0);
CvPoint2D64f Point3 = cvPoint2D64f(100.0,300.0);

CvPoint3D32f Point4 = cvPoint3D32f(100.0,200.0,300.0);
CvPoint3D64f Point5 = cvPoint3D64f(100.0,100.0,100.0);

CvPoint2D32f Point6 = cvPointTo32f(Point1);
CvPoint Point7 = cvPointFrom32f(Point6);

printf("2 Dimension/n");
printf("Point1 : (%d ,%d)/n",Point1.x,Point1.y);
printf("Point2 : (%.1f,%.1f)/n",Point2.x,Point2.y);
printf("Point3 : (%.1f,%.1f)/n",Point3.x,Point3.y);

printf("/n3 Dimension/n");
printf("Point4 : (%.1f,%.1f,%.1f)/n",Point4.x,Point4.y,Point4.z);
printf("Point5 : (%.1f,%.1f,%.1f)/n",Point5.x,Point5.y,Point5.z);

printf("/nConvert/n");
printf("Point6 : (%.1f,%.1f)/n",Point6.x,Point6.y);
printf("Point7 : (%d,%d)/n/n",Point7.x,Point7.y);

}
