The invention discloses an adjacent railway jacking construction pipeline deformation monitoring method based on video processing, and belongs to the technical field of deformation monitoring, and the method comprises the following steps: S1, in a preset time, shooting a construction pipeline video in an adjacent railway jacking process, and splitting the construction pipeline video into a plurality of frames of construction pipeline images; s2, constructing a qualified image screening model, and extracting a qualified construction pipeline image set from the plurality of frames of construction pipeline images by using the qualified image screening model; and S3, determining a construction pipeline deformation monitoring result according to the qualified construction pipeline image set. The method can ensure that the image source of construction pipeline monitoring is accurate, the image quality is high, the interference of unnecessary factors on deformation monitoring is reduced, and the monitoring efficienc
