Abstract

The invention discloses a visual modeling method and system based on space-time big data. The method comprises the steps: carrying out the labeling classification of a spatial feature data set, an attribute feature data set, and a time scale feature data set, and obtaining a first business feature data set; obtaining a corresponding visual image data set according to the first business feature data set; inputting the business spatio-temporal database and the business management indexes into a deep convolutional neural model for data training to obtain a first business spatio-temporal data model; performing incremental learning on the first service spatio-temporal data model according to the first service periodic change feature to obtain a second service spatio-temporal data model; and performing support management on the first construction project information according to the second business spatio-temporal data model. The technical problem that in the prior art, the business models are numerous and frequently changed and adjusted, and data cannot be rapidly extracted to meet business requirements is solved.

Description

technical field

[0001] The invention relates to the field of model building, in particular to a visual modeling method and system based on spatiotemporal big data. Background technique

[0002] In the process of promoting the construction of smart cities, more and more spatio-temporal big data are accumulated. Spatio-temporal data refers to spatial data that has time elements and changes with time. . These spatio-temporal data not only have obvious spatial distribution characteristics, but also have the characteristics of huge data volume, nonlinearity and time variation, and have the comprehensive characteristics of multi-source, massive and fast update.

[0003] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found that the above-mentioned technology has at least the following technical problems:

[0004] In the existing technology, there are many business m...
