The invention discloses a rail roadbed settlement measurement method based on mileage and image measurement, and relates to the field of settlement measurement. According to the rail roadbed settlement measurement method, the rail roadbed sparse three-dimensional reconstruction is completed through image feature matching and binocular intersection, the adjacent frame sparse reconstruction point splicing is achieved through a mileage measurement device and feature matching, and therefore automatic monitoring and rapid measurement of rail roadbed settlement are completed. The rail roadbed settlement measurement method has the advantages of being low in cost, high in work efficiency, result repeatability and measurement accuracy, and the like.
