The invention belongs to the technical field of displacement monitoring, and particularly provides a high-rise structure dynamic displacement monitoring method based on a digital image, which includes an image collecting system and a data analyzing system, wherein the image collecting system is mounted on a measuring point of a to-be-monitored building with a lens of the image collecting system facing toward the ground, the included angle between the lens direction and the vertical direction is theta, and the image collecting system is used for collecting the ground image data; and the data analyzing system calculates the translational displacement and the torsion angle of the measuring point of the building according to the collected ground image data. The method can perform long-time, highly-precise, real-time and automatic monitoring of the dynamic displacement of the high-rise structure, and has the advantages of convenience for mounting and simplicity for popularization and application.
