PTZ camera operating system

A pan-tilt-zoom (PTZ) camera operating system comprising:

• a nonvolatile memory configured to store a hemispherical fisheye image generated using individual images within a motion range captured by a PTZ camera;
• a processor configured to execute a surveillance area setting user interface (UI) for setting a surveillance area using the hemispherical fisheye image stored in the nonvolatile memory;
• a display unit configured to output a surveillance area setting UI executed by the processor to a screen;
• a user input unit comprising at least one of a keyboard, a mouse, and a touch panel, wherein the user input unit is configured to receive input of a user operation for setting the surveillance area;
• a communication unit configured to communicate with the PTZ camera,
• wherein the surveillance area setting UI outputs the hemispherical fisheye image stored in the nonvolatile memory to the screen, and sets, as the surveillance area, an area selected through the user operation from the hemispherical fisheye image output to the screen,
• wherein the processor comprises:
• a fisheye image generator configured to generate a hemispherical fisheye image using individual images within the motion range captured by the PTZ camera;
• a fisheye image storage controller configured to perform a control operation to store the hemispherical fisheye image generated by the fisheye image generator in the nonvolatile memory;
• a surveillance area setting UI output controller configured to perform a control operation to output the surveillance area setting UI for setting the surveillance area through the display unit;
• a coordinate mapping processor configured to generate a PTZ camera driving table by mapping fisheye image coordinates included in the surveillance area set by the surveillance area setting UI to PTZ camera driving coordinates;
• and
• a camera driving table storage controller configured to perform a control operation to store the PTZ camera driving table generated by the coordinate mapping processor in the nonvolatile memory.
