基于免像控空地融合技术的古式建筑精细建模研究

Research on Fine Modeling of Ancient Architecture Based on Image-free Space-Ground Fusion Technology

古式建筑因其具有结构复杂、构件精细等特点,采用常规倾斜摄影建模方法,通常存在房檐底部拉花、立面纹理不清晰等问题。该文提出一种基于单镜头无人机空中井字航线影像、贴近环拍视频分帧影像、多向空地衔接影像和地面近景照片数据的免像控空地融合精细建模方法,选取青岛即墨古城的古式建筑为实验对象,将该方法与常规倾斜摄影建模方法进行对比分析。实验结果表明,该文方法在生产效率、纹理精细度和空间精度上均要优于常规倾斜摄影建模方法。

Because of its complex structure and fine components,the conventional oblique photography modeling method usually has some problems,such as flower drawing at the bottom of the eaves,unclear facade texture and so on.This paper presents a fine modeling method of image-free air-ground fusion based on single-lens UAV air well route image,close-to-loop video framing image,multi-directional air-ground connection image and ground close-up photo data.The ancient architecture of Jimo ancient city of Qingdao is selected as the experimental object,and this method is compared with the conventional oblique photography modeling method.The experimental results show that the proposed method is superior to the conventional oblique photography modeling method in terms of production efficiency,texture fineness and spatial accuracy.
