摘要: 针对建筑物模型的规则性问题,基于一幅或多幅非标定图像,对建筑物结构进行多视角三维场景重建,得到360°观测模型。区别于传统三维重建方法,该方法无需先标定摄像机参数与逐点配准、不依赖深度数据和高分辨率图像。实验结果表明该方法解决了单张图像方向性感知视野受限的问题,在系统复杂度和速度上优于传统方法。

Abstract: Aiming at the problem of the regularity for building model, this paper rebuilds multi-view scene reconstruction of building from single or multiple uncalibrated images, gets a 360 degrees view of the model. Different from the traditional 3D reconstruction methods, this method doesn’t need intrinsic camera parameters in advance, rely on range data or high-resolution images and pointwise registration. Experimental result shows that this method overcome directional sensing range and display for single image, it is faster and simpler than traditional methods.

Key words: 3D scene reconstruction, perspective projection, affine transform
