Video picture drift identification method and device, computer equipment and storage medium

The embodiment of the invention provides a video picture drift identification method and device, computer equipment and a storage medium, and relates to the technical field of computers. The method comprises the following steps: defining a video picture as a two-dimensional matrix F; normalizing Y component data of a first image to be identified and Y component data of a second image to be identified in a YUV color space form, and respectively filling the Y component data into a matrix F, the first image and the second image being adjacent frame images; calculating an up-down drift feature vector S according to the matrix F filled based on the first image, and calculating an up-down drift feature vector S'according to the matrix F filled based on the second image; and forming a convolution kernel by a part of numerical values in the vector S, searching a correlation relation in the vector S ', and identifying the video picture drift according to the correlation relation. Evaluation is carried out in a mode of
