在 20 世纪 90 年代和 2000 年代初涉足 3D 图形领域后，我会说你不会找到任何合适的东西，因为这是一个非常困难的问题。
不过，我检查了 Insight3d 网站，它似乎确实是合法的。
There was a question on Super User that asked:
"Is there any free/open source software that converts photos to 3d models?"
but is has since been deleted. (It's here for anyone that has > 10K rep on SU)
From the accepted answer:
I think insight3d does exactly what you are asking for.
Having been involved in 3d graphics in the 1990s and early 2000s I would have said that you wouldn't have found anything suitable as it is a very hard problem.
However, I checked out the insight3d site and it does seem to be legitimate.
另一方面，我知道游戏和动画行业每天都会使用 3D 扫描仪......但我敢打赌它们非常昂贵，并且不符合您的要求。
PS 不要把我的话当作绝对的，因为我只是一个爱好者，而且我已经有一段时间没有看到最先进的了。
I think this is a hot research topic... I've seen many technical demos showing partial reconstructions, in domains like architecture or simple geometrical objects; so I'm not sure if you could find a drop in library that just works for every model (with just a few photographs).
Programming it from scratch is insane. Just to make the mathematical models could take a lot of time to skilled mathematicians (small improvements in the area could be worth a Ph.D.'s work), not to talk to "plain" computer scientists... and the implementation wouldn't be easy either.
In the other part, I know there exist 3d scanners that are used everyday in the games and animation industries... but I'd bet they are quite expensive, and don't fit with your requirements.
P.S. Don't take my words as definitive, as I'm just an aficionado and there's been a time since I looked the state of the art.
Try AgiSoft Photoscan... there's a trial version which works fully but won't export models, or save. But it's worth a try. It builds Meshes which are quite amazing. Often look better than Photosynth's point cloud results.

我认为这是一个热门的研究主题......我见过许多技术演示，展示了部分重建，在建筑或简单的几何对象等领域；所以我不确定你是否能找到一个适合每个模型的库（只有几张照片）。
从头开始编程是疯狂的。对于熟练的数学家来说，仅仅制作数学模型可能会花费大量时间（该领域的微小改进可能值得博士的工作），而不是与“普通”计算机科学家交谈......并且实现不会也不容易。

您是否考虑过使用立体相机来拍照？
Have you considered using stereo cameras to take the pictures?
Microsoft 的 Photosynth 处于同一水平，但可能不够精确以满足您的需求。
Microsoft's Photosynth is in the same ballpark, but may not be precise enough for your needs.
尝试 AgiSoft Photoscan...有一个试用版，可以完全运行，但不会导出模型或保存。但值得一试。它构建的网格非常令人惊奇。通常看起来比 Photosynth 的点云结果更好。
您还可以查看 Bundler 和 PMVS2...但它们比较难适应。

You can also look at Bundler and PMVS2... but they're a bit more fiddly to get used to.
