Abstract

The embodiment of the invention discloses a multi-source spatio-temporal data fusion method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring multi-source spatio-temporal information, and converting each piece of spatio-temporal information according to a unified preset data format to obtain spatio-temporal data of each data source; respectively calculating the similarity between each piece of spatio-temporal data in each data source and each piece of spatio-temporal data in other data sources; matching the spatio-temporal data among the different data sources according to the similarity; and fusing the spatio-temporal data of each data source according to a matching result. According to the technical scheme provided by the embodiment of the invention, the fusion of the multi-source spatio-temporal data is realized, and the redundancy of the spatio-temporal data for each user is reduced, so that the spatio-temporal data can be better utilized to carry out projects such as urban safety management and urban planning.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a multi-source spatio-temporal data fusion method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of mobile Internet and wireless technology, as well as the improvement of the Beidou positioning system, public transportation, taxis, online car-hailing and shared bicycles have resulted in explosive growth of spatio-temporal data. How to use historical trajectory data and artificial intelligence technology to integrate multiple The source trajectory IDs are unified to form a multi-source ID library based on time and space, which has guiding significance for improving urban safety management and urban planning. [0003] At present, the scale of the entire city is huge, and the population of a megacity can reach tens of millions, and the amount of data generated is also huge. The current cl...
