1. A video image interference detection method, 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.
