Camera content anomaly detection method and device, equipment and storage medium

The invention provides a camera content anomaly detection method and device, equipment and a storage medium, and the method comprises the steps: obtaining an initial image of a camera based on an initial static position of the camera, sending a preset first action instruction to the camera, obtaining an image set when the camera executes the action instruction, and obtaining a first image set when the camera executes the action instruction; the image set comprises a plurality of continuous image frames; slitting the initial image and each image frame to obtain a plurality of initial sub-image blocks corresponding to the initial image and a plurality of sub-image blocks corresponding to each image frame; performing feature similarity comparison on the sub-image blocks with the same arrangement position and the initial sub-image block to obtain a feature similarity comparison result; and according to a feature similarity comparison result, determining that the content of the camera is abnormal.
