单片建筑物近景影像3维重建预处理方法的研究

Researching on Pretreatment Apporaches of Architecture’s 3D Reconstruction Based on a Single Close-Range Image

在进行建筑物3维重建的过程中,在提取建筑物信息之前,先对整幅图像进行预处理是很有必要的。在本论文中,运用类判别分析法从原始影像中分割出感兴趣的目标———建筑物区域,在处理的过程中,综合运用多种方法,如数学形态学等方法生成有利于进行特征提取、边缘检测的新图像,便于更进一步的工作。文中还介绍了作者根据类判别分析法和数学形态学原理,利用VisualBasic6.0开发建筑物近景影像3维重建应用系统中预处理模块的实验分析。

It is necessary to pretreat the whole image before the acquisition of 3D building based on monocular image processing. In this paper, it describes how to make use of multi-method and theory during the pretreatment process. This paper also describes the pretreatment module of Architecture＇s 3D Reconstruction System and analyses the experiment＇ result according to the Otsu method and morphologic theory.
