Zusammenfassung:The invention relates to a multi-scene video jitter detection method based on video monitoring. The method comprises the following steps: acquiring two adjacent frames of images of a conference monitoring picture; feature point searching and matching are carried out on the obtained two frames of images; if the number of the matched feature points is smaller than a set threshold value, it is judged that the meeting place is switched, and picture jitter detection is not carried out at the moment; if the number of the matched feature points is greater than a set threshold value, judging that the meeting place is not switched, respectively calculating row and column projections of the two frames of images, respectively carrying out correlation operation on the row and column projections, taking an extreme value in a correlation value curve as a displacement between the two frames, and taking a vector absolute value as a displacement size; and when the displacement distance is greater than a set threshold value, j
