This class wraps intrinsic parameters of a camera.
It provides several constructors that can extract the intrinsic parameters from field of view, intrinsic matrix and projection matrix. :
cv::viz::Camera::Camera | ( | double | fx, |
double | fy, | ||
double | cx, | ||
double | cy, | ||
const Size & | window_size | ||
) |
Constructs a Camera.
fx | Horizontal focal length. |
fy | Vertical focal length. |
cx | x coordinate of the principal point. |
cy | y coordinate of the principal point. |
window_size | Size of the window. This together with focal length and principal point determines the field of view. |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
fov | Field of view (horizontal, vertical) |
window_size | Size of the window. Principal point is at the center of the window by default. |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
K | Intrinsic matrix of the camera. |
window_size | Size of the window. This together with intrinsic matrix determines the field of view. |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
proj | Projection matrix of the camera. |
window_size | Size of the window. This together with projection matrix determines the field of view. |
void cv::viz::Camera::computeProjectionMatrix | ( | Matx44d & | proj | ) | const |
Computes projection matrix using intrinsic parameters of the camera.
proj | Output projection matrix. |
