The intrinsic matrix (commonly represented in equations as
K) allows you to transform 3D coordinates to 2D coordinates on an image plane using the pinhole camera model.
fy are the pixel focal length, and are identical for square pixels. The values
oy are the offsets of the principal point from the top-left corner of the image frame. All values are expressed in pixels.
