WEEK10.Homework4/30.

今天老師上課一開始就教我們如何設定Opencv2.1

以後做院長的影像處理作業終於可以用自己的電腦試試看了~~耶以~~~

以下是成果:

成功做出來真開心!:)

然後我忘記把我做的步驟截圖了........

接下來我們做的是讀取2D圖片和3D會旋轉的茶壺

讓他們同時出現 ,如下圖所示:

程式碼如下:

#include <GL/glut.h>

#include <opencv/highgui.h>

float angle=0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle, 0, 1,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glFlush();

    angle+=0.1;

}

int main(int argc, char**argv)

{

    IplImage * img = cvLoadImage("1.jpg");

    cvShowImage("2D", img);

    glutInit(&argc, argv);

    glutCreateWindow("3D");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    glutMainLoop();

}

再來我們做的是把這兩個東西結合在一起

就是一個有圖案的茶壺溜!

程式碼:

#include <GL/glut.h>

#include <opencv/highgui.h>

#include <opencv/cv.h>

float angle=0;

void display()

{

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(angle, 0, 1,0);

        glutSolidTeapot(0.3);

    glPopMatrix();

    glFlush();

    angle+=0.1;

}

void init()

{

    IplImage * img = cvLoadImage("1.jpg");

    cvCvtColor(img, img, CV_BGR2RGB);

    glEnable(GL_TEXTURE_2D);

    GLuint id;

    glGenTextures(1, & id );

    glBindTexture(GL_TEXTURE_2D, id);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);

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

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("3DFeastteapot");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    init();

    glutMainLoop();

}

以下是老師上課程式碼的解釋:

接下來就是貼到一顆球上囉!

如果你的圖片是地圖就可以做出一顆地球囉!

程式碼:

#include <GL/glut.h>

#include <opencv/highgui.h>

#include <opencv/cv.h>

float angle=0;

GLUquadric * quad;

void display()

{

    glEnable(GL_DEPTH_TEST);

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glPushMatrix();

        glRotatef(-200, 1, 0, 0);

        glRotatef(angle, 0, 1,0);

        gluQuadricTexture(quad, 1);

        gluSphere(quad, 0.5, 30, 30);

    glPopMatrix();

    glFlush();

    angle+=0.1;

}

void init()

{

    quad = gluNewQuadric();

    IplImage * img = cvLoadImage("1.jpg");

    cvCvtColor(img, img, CV_BGR2RGB);

    glEnable(GL_TEXTURE_2D);

    GLuint id;

    glGenTextures(1, & id );

    glBindTexture(GL_TEXTURE_2D, id);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);

    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);

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

}

int main(int argc, char**argv)

{

    glutInit(&argc, argv);

    glutCreateWindow("3DFeastteapot");

    glutDisplayFunc(display);

    glutIdleFunc(display);

    init();

    glutMainLoop();

}
