摘　　要：针对目前消防部队灭火救援作战中无CAD图样时建筑三维模型无法构建的问题,提出了基于微惯导技术与Unity3D建模技术,利用改进的三角剖分算法快速构建城市建筑三维模型的方法,并阐述了三维模型构建的详细过程。试验实例表明,通过该方法在无CAD图样时构建的三维建筑模型具有很好的可视化效果,并在灭火救援指挥作战中具有很强的实用性。Aimed at the problem that the building 3D model cannot be constructed when there were no CAD drawings in the fire fighting and rescue operations of the fire brigade,a method for quickly building a 3D model of urban buildings was proposed based on micro inertial navigation technology and Unity3D modeling technology using an improved triangulation algorithm,and the process of 3D model construction was expounded in details.Experimental examples showed that this method of the 3D building model without CAD drawings had a good visualization effect and was very practical in fire fighting rescue command operations.
