Method and system for automated video image focus change detection and classification

A method for evaluating a focus status of a camera, the method comprising:

• storing, in a memory, a reference image based on first image data received from the camera;
• receiving second image data from the camera in accordance with a predetermined schedule;
• classifying, by a processor, a focus status of a test image of the second image data;
• determining, by the processor, whether the camera is in a state of focus based on the focus status of the test image;
• changing a focus of the camera when the camera is determined not to be in the state of focus;
• and
• storing, in the memory, a new reference image based on third image data received from the camera, the third image data being received after changing the focus of the camera.

A non-transitory computer readable storage medium that stores a set of executable instructions for evaluating a focus status of a camera, the set of executable instructions, when executed by a processor, causing operations to be performed, the operations comprising:

• storing a reference image based on first image data received from the camera;
• receiving second image data from the camera in accordance with a predetermined schedule;
• classifying a focus status of a test image of the second image data;
• determining whether the camera is in a state of focus based on the focus status of the test image;
• changing a focus of the camera when the camera is determined not to be in the state of focus;
• and
• storing a new reference image based on third image data received from the camera, the third image data being received after changing the focus of the camera.
