Research on key technologies of 3D dynamic updating and scene fusion based on linear feature boundary
The construction of 3D China is an important measure to implement the strategy of digital China,safe China and digital economy.It is an important new national infrastructure in the new era,and the basic support for the construc-tion of ecological civilization and economic and social development.Since the"14th Five-Year Plan",various places have successively carried out a certain scale of real 3D construction projects,and accumulated different scales of real 3D floor data.How to make full use of the existing construction results and continue to ensure the timeliness and availability of 3D data has become the next urgent problem to be solved.In this paper,a dynamic updating and scene fusion scheme of line-ar feature boundary is proposed based on the scene feature attributes of 3D real data.Based on the original scene data,the boundary line of the nearest linear feature in the target update area is taken as the actual update range,and it is processed by cutting,splicing,color blending and fusion,etc.,to achieve seamless fusion of multi-phase real 3D data.
