Method for constructing urban space holographic map based on multi-source big data fusion

Abstract

The present invention discloses a method for constructing an urban space holographic map based on multi-source big data fusion, and urban buildings, roads, municipal greening, infrastructure, public transportation, human flow distribution information, and regional hot search in the entire urban space are involved. By using the big data processing method combined with the above five kinds of collected information, and through the image processing system and the three-dimensional image processing technology, urban buildings, roads, municipal greening, infrastructure, public transportation, humanflow distribution information and regional hot search are combined with the mapping software. According to the method for constructing an urban space holographic map based on multi-source big data fusion, urban buildings, roads, municipal greening, infrastructure, public transportation, human flow distribution information and regional hot search are combined with the mapping software, and the bigdata processing technology is combined with the holographic map, so that the city map can be three-dimensional and multi-layered, and the urban space holographic map based on the multi-source big data fusion can be realized.

Description

technical field [0001] The invention relates to the technical field of construction methods of holographic maps, in particular to a construction method of urban space holographic maps based on multi-source big data fusion. Background technique [0002] Big data refers to a collection of data that cannot be captured, managed, and processed by conventional software tools within a certain period of time. It is a massive, high-growth rate that requires a new processing model to have stronger decision-making power, insight and discovery, and process optimization capabilities. and diverse information assets. [0003] The holographic map is based on computer holographic technology, information communication technology and laser technology. The airborne coherent radar uses a highly coherent microwave generator. The ground reflection signal received at each point on the ground and another reference beam are superimposed on the photosensitive film to generate a coherent pattern, whic...
