Detailed Description

Class which enables to project an image in the 3D space and get the view of a virtual camera.

The image is represented by a rectangular image whose corners coordinates are known in the 3D frame linked to the 3D rectangle.

The 3D rectangle is positionned relative to a virtual camera (represented by its intrinsic parameters). Indeed, the pose $ cMt $ has to be given by the user of the class.

And finally, the view of the virtual camera is given by the geImage() method.

You can use a colored or a gray scaled image.

To avoid the aliasing especially when the camera is very near from the image plane, a bilinear interpolation can be done for every pixels which have to be filled in. By default this functionality is not used because it consumes lot of time.

The following example explain how to use the class.

#include <visp3/core/vpImage.h>
#include <visp3/robot/vpImageSimulator.h>
int main()
{
vpImage<vpRGBa> Icamera(480,640,0);
vpImage<vpRGBa> Iimage(60,60);
// Initialise the image which will be projected into the image Icamera
vpRGBa colorb(0,0,255);
vpRGBa colorw(255,255,255);
vpRGBa colorr(255,0,0);
for(int i = 0; i < 60; i++)
{
for(int j = 0; j < 20; j++)
Iimage[i][j] = colorb;
for(int j = 20; j < 40; j++)
Iimage[i][j] = colorw;
for(int j = 40; j < 60; j++)
Iimage[i][j] = colorr;
}
// Initialise the 3D coordinates of the Iimage corners
vpColVector X[4];
for (int i = 0; i < 4; i++) X[i].resize(3);
// Top left corner
X[0][0] = -1;
X[0][1] = -1;
X[0][2] = 0;
// Top right corner
X[1][0] = 1;
X[1][1] = -1;
X[1][2] = 0;
// Bottom right corner
X[2][0] = 1;
X[2][1] = 1;
X[2][2] = 0;
//Bottom left corner
X[3][0] = -1;
X[3][1] = 1;
X[3][2] = 0;
vpImageSimulator sim;
sim.init(Iimage, X);
sim.setCameraPosition(vpHomogeneousMatrix(0,0,5,vpMath::rad(60),vpMath::rad(0),0));
vpCameraParameters cam(868.0, 869.0, 320, 240);
sim.getImage(Icamera,cam);
return 0;
}
