    {
        CameraParams();
        CameraParams(const CameraParams& other);
        const CameraParams& operator =(const CameraParams& other);
        Mat K() const;

        double focal; // Focal length
        double aspect; // Aspect ratio
        double ppx; // Principal point X
        double ppy; // Principal point Y
        Mat R; // Rotation
        Mat t; // Translation
    };
