摘　　要：本文以车载全景影像数据为研究对象,根据理想球面模型下全景摄影的共线条件,针对建筑立面、道路面、三角网模型、连续面四个方面进行纹理提取方法的研究与实验,实现了从车载全景影像中提取出目标纹理信息。本文方法可在城市沿街立面整治、建筑物三维重建、建筑立面测绘等领域中应用。According to the collinear equations of panoramic photography,and under the ideal spherical model,this paper conducts the research and experiment on the texture extraction method in the four aspects of building facade,road surface,triangulation model and continuous surface,and realizes the extraction of the texture information from the vehicle panoramic image.The method can be applied in the fields of urban street facade renovation,three-dimensional reconstruction of buildings,and building facade surveying and mapping.
