摘要
三维重建是计算机视觉领域、遥感领域、摄影测量领域等研究的热点之一。自顶向下的重建方法从建筑物的整体结构出发,不容易受到噪声的干扰。为了对单幅高分辨率遥感图像中的建筑物进行准确重建,提出一种自顶向下的建筑物重建方法,在优化过程中,设计了新的转移核函数,使得优化过程既可以跳出局部最优,又可以达到较快的收敛速度。利用IKONOS上1m分辨率的遥感图像及近1m分辨率的仿真图像进行验证,实验结果表明,同时使用特殊转移核和基本转移核的自顶向下的方法能够更加准确地重建建筑物,重建结果要优于仅仅使用基本转移核的结果,并且由于使用了特殊的转移核,能跳出局部最优,具有很强的鲁棒性。
3D reconstruction is one of the hot researches in the field of computer vision, remote sensing, photogrammetry and so on. Since the top-down reconstruction approach starts from the overall structure of the building, it is not suscepti- ble to noise disturbance. In order to reconstruct buildings from a single high resolution remote sensing image, a top-down building reconstruction method is proposed. In the process of optimization, special transition kernels are designed in or- der to achieve convergent extraction results and get rid of local minimum. Experimental results show that the proposed method can reconstruct building more accurately than method＇s only using basic transition kernels by using IKONOS 1 m resolution on remote sensing images and almost 1 m resolution on simulated images. Moreover, it can get rid of local minimum and has strong robustness with respect to the disturbance of background noise. ..
