Abstract

The invention discloses a method and equipment for constructing a simulation city model, and relates to the field of simulation modeling. The construction method of the simulation city model comprisesthe steps that an outdoor model of a building obtained through oblique photogrammetry and an indoor model of the building constructed through BIM are fused to obtain a simulation building model; wherein the outdoor model and the indoor model are fused by placing coordinate data of the outdoor model and coordinate data of the indoor model in the same coordinate system; and fusing the simulation building model with a ground surface model to obtain a simulation city model. The method is used for solving the problems that an existing three-dimensional modeling method cannot simply, effectively and truly restore the real scene environment of a city, and indoor and outdoor effective fusion modeling of a building cannot be achieved.

Description

technical field [0001] The invention relates to the field of simulation modeling, in particular to a method and equipment for constructing a simulation city model. Background technique [0002] Urban operations usually refer to actions with the direct purpose of defending or capturing a city. Urban operations are listed as a single type of action, with distinctive features such as extremely complex battlefield environments, limited use of equipment advantages, and fierce competition for buildings. Extensive use of various simulation training systems with virtual reality technology as the core is a prominent feature of military urban action training in many developed countries. Battlefield environment simulation is one of the indispensable and important links. It can provide commanders with a virtual battlefield environment and battlefield situation in a real and fast manner, so that the effectiveness of action command is unprecedentedly improved. [0003] The acquisition a...
