week05今天教open cv的使用
1.OPENCV 前置設定
Install opencv2.1
安裝第三步 Add OpenCV to system PATH (中間的)
1.Setting-Compiler,目錄compiler要加入include 目錄
2.Setting-Compiler,目錄linker要加入lib目錄
3.Setting-Compiler,linker setting要加入cv210 cxcore210 highgui210三個檔名
*貼圖程式碼
#include <opencv/highgui.h> ///Open的內建外掛
int main()
{
IplImage * img = cvLoadImage("c:/micky.jpg");
cvShowImage("img",img);
cvWaitKey(0);/// 等任意鍵，再繼續
}
https://jsyeh.org/3dcg10/下載:1.data 2.win32->解壓縮win32 , 把data資料夾->windows資料夾
*茶杯和貼圖整合一起放出
#include <GL/glut.h>
#include <opencv/highgui.h>
void display()
{
glutSolidTeapot(0.3);
glutSwapBuffers();
}
int main(int argc, char *argv[])
{
IplImage * img = cvLoadImage("c:/micky.jpg");
cvShowImage("img",img);
glutInit(&argc, argv);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);
glutCreateWindow("week05-1 Texture");
glutDisplayFunc(display);
glutMainLoop();
}
*地球茶杯
