The embodiment of the invention provides a video data lag detection method and device, equipment and a storage medium. The method comprises the following steps: acquiring to-be-detected video data, performing frame extraction processing on the video data according to a preset interval time, acquiring multiple frames of pictures, and storing the multiple frames of pictures according to a frame extraction sequence of the multiple frames of pictures; obtaining a stored first picture and a second picture adjacent to the first picture; according to the first picture and the second picture, determining an ROI region of the first picture and an ROI region of the second picture; calculating the similarity between the ROI region of the first picture and the ROI region of the second picture; and if the similarity between the ROI region of the first picture and the ROI region of the second picture is greater than a first threshold value, determining that the first picture is a lagging abnormal picture. The method and th
