Description
technical field [0001] The invention belongs to the technical field of drainage pipe network data processing, and in particular relates to a preprocessing method and device for drainage pipe network data. Background technique [0002] Urban waterlogging refers to the phenomenon of accumulated water disasters in cities due to heavy or continuous precipitation exceeding the urban drainage capacity. Urban waterlogging early warning, post-disaster loss assessment, and drainage network planning have very important research value in solving urban waterlogging problems. [0003] The drainage network mechanism model is one of the important tools for studying urban waterlogging problems. The drainage network data obtained by manual surveying and mapping is the core input condition of the drainage network mechanism model, such as the establishment method of the drainage network data model disclosed in patent document CN112836321A and Patent document CN113190937A discloses a method fo...
