Research And Development Of Indoor 3D Map Based On LBS

Electronic maps are map services developed using technologies such as network and geoinformatics.Based on Location Based Service(LBS),it has achieved certain development in the field of smart cities in recent years.Compared with outdoor maps,today's indoor map research is not yet mature.At present,indoor maps are mainly expressed in simple three-dimensional geometric shapes,or in the form of two-dimensional plans,and the representation is relatively independent.This subject mainly aims at the current shortcomings of indoor map performance,adopts WebGL technology front-end programming and modeling,and combines LBS related requirements to research and develop an indoor three-dimensional map engine presented on the Web side.And expand the technology to the outdoor park area,integrate outdoor and indoor maps for a comprehensive display.Combining with the development background of electronic maps,the paper first introduces the development status of three-dimensional maps,and then investigates the development status of indoor maps at home and abroad,and learns that the current indoor maps need to be developed.Then,by analyzing the structure and characteristics of the indoor space,the fusion expression method of the indoor and outdoor maps is studied,and according to the processing requirements of the data structure of the indoor space model,a new map model presentation scheme is designed to present a three-dimensional map model.Next,the paper combines the indoor map and user interaction requirements,studies and implements some interactive support functions of the map,and elaborates its specific implementation principle and implementation process.Among them,a new efficient implementation scheme is designed in the aspects of adaptive zooming of the identification model and occlusion detection.At the end of the article,the map engine engineering development environment,overall structure,and various modules are explained.In the form of a legend,the engine is presented in all aspects,and its performance is tested and evaluated.The results prove that the engine is not only beautiful in appearance and good in interactive function,but also has low time expenditure and excellent fluency in all aspects of performance indicators,meets the needs of LBS related services,and has certain research significance and practical value in the field of electronic indoor maps.
