李先生05

 1.opencv安裝

2.選項選2或3

3.不要更換目標資料夾

4.重開codeblocks

5.設定Settings-compiler要加入三個設定

5.1.search 目錄 compiler 的include 目錄 加 C:\OpenCV2.1\include

5.2.search 目錄 linker 的lib 目錄 加 C:\OpenCV2.1\lib

5.3.加入linker 設定的 3個檔名cv210 cxcore210 highgui210

6. 新增file week05_opencv.cpp

下載圖片存入c槽並命名image.jpg

7.執行

8.進入老師的網站下載課本範例

9.

解壓縮windows.zip再把data.zip解壓縮放到windows中

10.從上課軟體下載freeglut

 11.將壓縮檔解壓到桌面

12.點開freeglut後復製其連結

13.點開lib後將freeglut.a復製

14.改名為libglut32.a (124KB)

15.到codeblock開新的專案 file > project,(檔名為week05_opencv)

16..將之前的11行程式碼和剛剛opencv的三行貼上

#include <GL/glut.h>

#include <opencv/highgui.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char*argv[])

{

    IplImage * img = cvLoadImage("c:/image.jpg");

    cvShowImage("opencv",img);

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week05");

    glutDisplayFunc(display);

    glutMainLoop();

}

17.到codeblock開新的專案 file > project,(當名為week05_opencv_opengl_myTexture)

18.將https://gist.github.com/jsyeh/5ed01210559721ec71b659b3ffed2dd7

裡的18行貼上和剛剛的程式碼

#include <opencv/highgui.h> ///使用 OpenCV 2.1 比較簡單, 只要用 High GUI 即可

#include <opencv/cv.h>

#include <GL/glut.h>

int myTexture(char * filename)

{

    IplImage * img = cvLoadImage(filename); ///OpenCV讀圖

    cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)

    glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能

    GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID

    glGenTextures(1, &id); /// 產生Generate 貼圖ID

    glBindTexture(GL_TEXTURE_2D, id); ///綁定bind 貼圖ID

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖T, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); /// 貼圖參數, 超過包裝的範圖S, 就重覆貼圖

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST); /// 貼圖參數, 放大時的內插, 用最近點

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

    return id;

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char*argv[])

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week05");

    glutDisplayFunc(display);

    myTexture("c:/image.jpg");

    glutMainLoop();

}

19.新增week05_opencv_opengl_myTexture_glTexCoord2f

#include <opencv/highgui.h> ///使用 OpenCV 2.1 比較簡單, 只要用 High GUI 即可

#include <opencv/cv.h>

#include <GL/glut.h>

int myTexture(char * filename)

{

    IplImage * img = cvLoadImage(filename); ///OpenCV讀圖

    cvCvtColor(img,img, CV_BGR2RGB); ///OpenCV轉色彩 (需要cv.h)

    glEnable(GL_TEXTURE_2D); ///1. 開啟貼圖功能

    GLuint id; ///準備一個 unsigned int 整數, 叫 貼圖ID

    glGenTextures(1, &id); /// 產生Generate 貼圖ID

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST); /// 貼圖參數, 縮小時的內插, 用最近點

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, img->width, img->height, 0, GL_RGB, GL_UNSIGNED_BYTE, img->imageData);

    return id;

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glBegin(GL_POLYGON);

        glTexCoord2f(0,0);glVertex2f(-1,-1);

        glTexCoord2f(0,1);glVertex2f(-1,+1);

        glTexCoord2f(1,1);glVertex2f(+1,+1);

        glTexCoord2f(1,0);glVertex2f(+1,-1);

    glEnd();

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc,char*argv[])

{

    glutInit(&argc,argv);

    glutInitDisplayMode(GLUT_DOUBLE|GLUT_DEPTH);

    glutCreateWindow("week05");

    glutDisplayFunc(display);

    myTexture("c:/image.jpg");

    glutMainLoop();

}

20.google 下載earth map滿版

開啟新專案 week05_rotating_earth
