VISP_EXPORT std::ostream & | operator<< (std::ostream &os, const vpImageSimulator &) |
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 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.

You can choose if you want to use a colored or gray scaled image.
col | : Enable to choose the color space to use for the image which is projected. |
By default the class uses colored images.

Get the view of the virtual camera. Be careful, the image I is modified. The projected image is not added as an overlay!
To take into account the projection of several images, a matrix is given as argument. This matrix contains the z coordinates of all the pixel of the image in the camera frame. During the projection, the pixels are updated if there is no other plan between the camera and the projected image. The matrix is updated in this case.

Get the view of the virtual camera. Be careful, the image I is modified. The projected image is not added as an overlay! With this method, a list of image is projected into the image. Thus, you have to initialise a list of vpImageSimulator. Then you store them into a vpList. And finally with this method you project them into the image . The depth of the 3D scene is managed such as an image in foreground hides an image background.
The following example shows how to use the method:

list | : List of vpImageSimulator to project |
