摘要
针对静态三维地图生产主要依靠人工处理,成本高昂、效率低下且仅仅展示城市景观的一个方向、生产周期长、更新效率低等问题,提出了一种多角度模式下的静态三维城市地图快速生成方法。以武汉市三维城市地图为例,证明了该方法的有效性和可靠性。
Aiming to deal with the problem that static 3 D map production mainly rely on manual processing which is expensive,ineffective and only present urban mode in one direction with long production cycle and low update efficiency.This paper proposes a method for rapid formation of city level static 3 D map in multi-angle mode.We employ the method which automatically extracting contours of buildings on oblique view maps to reduce the amount of manual processing and then we use data matching method to get the contours of buildings with rich attributes.In order to obtain better display effect,we also use a high precision resampling algorithm to resampling the static 3 D map.Finally the validity and feasibility of this method are proved through the experiments on 3 D city models of Wuhan,Hubei.
