We present a novel image stitching approach, which can produce visually plausible panoramic images with input taken from different viewpoints. Unlike previous methods, our approach allows wide baselines between images and non-planar scene structures. Instead of 3D reconstruction, we design a mesh-based framework to optimize alignment and regularity in 2D. By solving a global objective function consisting of alignment and a set of prior constraints, we construct panoramic images, which are locally as perspective as possible and yet nearly orthogonal in the global view. We improve composition and achieve good performance on misaligned areas. Experimental results on challenging data demonstrate the effectiveness of the proposed method.
我们提出了一种新颖的图像拼接方法,能够从不同视角输入生成视觉上逼真的全景图像。与以前的方法不同,我们的方法允许图像之间存在宽基线和非平面场景结构。我们不是进行 3D 重建,而是设计了一个基于网格的框架来优化 2D 中的对齐和规则性。通过求解由对齐和一组先验约束组成的全局目标函数,我们构建了全景图像,这些图像在局部尽可能具有透视效果,但在全局视图中几乎是正交的。我们改进了构图,并在错位区域取得了良好的效果。在具有挑战性的数据上的实验结果证明了所提出方法的有效性。
