Abstract
The invention discloses a visual modeling method and system based on spatiotemporal big data, wherein the method includes: labeling the spatial feature data set, the attribute feature data set and the time scale feature data set Classify to obtain a first business feature data set; obtain a corresponding visual image data set according to the first business feature data set; input the business spatio-temporal database and the business management indicators into a deep convolutional neural model for data training, Obtain a first business spatio-temporal data model; perform incremental learning on the first business spatio-temporal data model according to the first business cycle change characteristics to obtain a second business spatio-temporal data model; according to the second business spatio-temporal data model, The first construction project information is supported and managed. It solves the technical problem that there are many business models in the prior art and they are often changed and adjusted, which is not conducive to quickly extracting data to meet business needs.
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...
