Video image interference detection method, system, device and medium

One or more nonvolatile computer-readable storage mediums, configured to store computer-readable instructions, wherein the computer-readable instructions, when executed by one or more processors, cause the one or more processors to perform the steps of the video image interference detection method, wherein the steps comprising:

• acquiring a background image and a current frame image;
• constructing an edge image of the background image and an edge image of the current frame image respectively;
• intersecting the edge image of the background image and the edge image of the current frame image to obtain a same boundary image between the edge image of the background image and the edge image of the current frame image;
• counting a first pixel number in the edge image of the background image and a second pixel number in the same edge image;
• and
• determining whether the current frame image is interfered according to a ratio of the first pixel number to the second pixel number,
• wherein the step of determining whether the current frame image is interfered according to a ratio of the first pixel number to the second pixel number comprises:
• in response to the ratio being greater than a first threshold, determining that the current frame image is not interfered;
• and
• in response to the ratio not being greater than the first threshold, determining that the current frame image is interfered.
