基于地基投影的建筑场景立面建模
Facade Modeling of Building Scene Based on Foundation Projection
摘要
Abstract
Multi-view modeling of building facades is usually confined to the reconstruction of sparse points, and has large errors in the reconstruction of different direction facades, demanding equipments and large systems. Aiming at this problem, a facade modeling algorithm based on foundation projection is presented. The order of facades in a view sequence is marked through scenes pretreatment. The algorithm calculates the 3D sparse points for each grouped view, and solves the scene baseline and rectifies facades synchronized by these sparse points. The local facade models are built via the baseline, and the three-dimensional facade model of scene is recovered after local models fusion. Experimental results show that the reconstruction has accurate, continuous three-dimensional structure and visualization texture modeled by this method, and can meet the needs of outdoor scenes modeling project. The facade angle error is less than 5° and line scale error is less than 1%within a certain proportion of the used sparse points.关键词
