image-processing - 像 Photosynth 一样重建场景

Question

有没有类似MS的开源代码Photosynth

Photosynth is a potent mixture of two independent breakthroughs: the ability to reconstruct the scene or object from a bunch of flat photographs, and the technology to bring that experience to virtually anyone over the Internet.

Using techniques from the field of computer vision, Photosynth examines images for similarities to each other and uses that information to estimate the shape of the subject and the vantage point the photos were taken from. With this information, we recreate the space and use it as a canvas to display and navigate through the photos.

Providing that experience requires viewing a LOT of data though—much more than you generally get at any one time by surfing someone’s photo album on the web. That’s where our Seadragon™ technology comes in: delivering just the pixels you need, exactly when you need them. It allows you to browse through dozens of 5, 10, or 100(!) megapixel photos effortlessly, without fiddling with a bunch of thumbnails and waiting around for everything to load. About this Release

Photosynth comes from a passionate little startup of two dozen people in Microsoft Live Labs. We are scientists, engineers, and designers working like crazy to deliver on Photosynth’s promise.

Answer 1

我发现的最接近开源 Photosynth 的是 Insight3D。在这里能找到它: http://insight3d.sourceforge.net/虽然 Insight3D 的部分内容是开源的并且可以免费下载，但其中包含一些非开源的库，例如 SIFT 特征检测器。

Bundler ( http://phototour.cs.washington.edu/bundler/ ) 也可能满足您的需求。 Bundler 与 Photosynth ( http://phototour.cs.washington.edu/ ) 密切相关，它需要更多才能运行。它没有任何 GUI，必须进行编译。

更新

我要报告运动应用程序开源结构领域的更新。 OpenMVG 是一个正在积极开发的照片重建项目 ( https://github.com/openMVG/openMVG )。它包含可重用的库以及一系列可执行文件，其中包含照片重建管道的各个步骤。

更新2

Mapillary 发布了一个名为 OpenSfM 的运动项目结构。 https://github.com/mapillary/OpenSfM 。它有一些可爱的功能，例如:

• 支持全景图
• 传感器与 GPS 和加速计融合
• 网络查看器的示例实现
