Treatment system and method for urban sewage surrounding environment model

Abstract

The invention relates to a treatment system and a method for an urban sewage surrounding environment model, belongs to the technical field of model management, and solves the problems that an existingsewage surrounding environment two-dimensional model is poor in intuition, high in map service updating frequency and low in efficiency. The system comprises a model establishing module for establishing sewage surrounding environment three-dimensional models corresponding to different time periods; a basic topographic map publishing module which publishes a basic topographic map of the surrounding environment of the target sewage; a conversion module which is used for performing tiling processing on the surrounding environment three-dimensional model to obtain sub-models with different resolutions, converting the sub-models into first text files respectively, correspondingly performing tiling processing on the basic topographic map, and respectively converting the basic topographic map into a second text file and a third text file; and a fusion module which is used for fusing the text files with the same resolution in the target time period to obtain a visual surrounding environment three-dimensional model corresponding to the target sewage. By means of the system, the surrounding environment of sewage can be visually known, and map service can be prevented from being frequently updated.

Description

technical field [0001] The invention relates to the technical field of model management, in particular to a processing system and method for a surrounding environment model of urban sewage. Background technique [0002] In the prior art, when urban management units monitor the surrounding environmental problems of sewage (black and odorous water bodies), they usually use two-dimensional GIS data and remote sensing images to monitor the sewage ( black and odorous water) monitoring model to form an objective sewage (black and odorous water) monitoring database, which can preliminarily judge the change of urban water from no black and odorous to severe black and odorous. This method is suitable for simple background environment, clear water system distribution, remote sensing image It is used in resource-rich areas for general surveys of black and odorous water bodies. [0003] The existing technology has at least the following defects. First, the traditional method is based o...
