Virtual camera panning and tilting

A method for displaying a virtual field of vision within a field of vision received from a video camera using a camera system, the method comprising:

• receiving, from a first video camera, a non-rectilinear image of a first field of vision;
• receiving, from an orientation adjustment switch, input defining an axis of a second field of vision within the first field of vision;
• determining, with an electronic processor, a non-rectilinear image of the second field of vision within the non-rectilinear image of the first field of vision;
• applying, with the electronic processor, a distortion correction method to the non-rectilinear image of the second field of vision to produce a rectilinear image of the second field of vision;
• and
• displaying, via a first display, the rectilinear image of the second field of vision.

A camera system comprising:

• a first video camera having a first field of vision;
• an orientation adjustment switch;
• a first display;
• and
• an electronic processor configured to:
• receive, from the first video camera, a non-rectilinear image of the first field of vision;
• receive, from the orientation adjustment switch, input defining an axis of a second field of vision within the first field of vision;
• determine a non-rectilinear image of the second field of vision within the non-rectilinear image of the first field of vision;
• apply a distortion correction method to the non-rectilinear image of the second field of vision to produce a rectilinear image of the second field of vision;
• and
• display the rectilinear image of the second field of vision on the first display.
