数转换2D影像转换成3D模型 [英] Converting several 2D images into 3D model

问题描述

我想尝试做软件非常类似 - 123dapp.com/catch。我真的想知道怎样的方​​式来实现这一点，例如Visual Studio中。如果它甚至有可能。我之所以我想知道我用这个软件是因为我想有一个程序，它所有这一切自动完成。我想codeA节目里，我只想导入多个图像，我会得到一个三维模型，比我的计划里面的模型的工作。这可能吗？如果是的话，任何人都可以帮助我进入这个？谢谢

I would like to try make software very similar to this - 123dapp.com/catch. I really would like to know the way how to achieve this in for example Visual Studio. If it is even possible. The reason I don`t want to use this software is because I would like to have a program that does all of this automatically. I want to code a program where I would just import several images and I would get a 3D model and than work with the model inside my program. Is this possible? If so, can anyone help me to get into this? Thank you

原因我在这里写这篇文章，是因为我不`吨知道从哪里开始研究这个问题。

推荐答案

您正在寻找的是从运动（SFM）管道的结构。写作时自己还需要一段时间;它是一个复杂的系统。这些步骤是

What you are looking for is a Structure from Motion (SFM) pipeline. Writing one yourself will take some time; its a complex system. The steps are

• 在检测它指向的图片显示的相同点现场（特征匹配）的。
• 估计每个图像的相机位置。
• 在使用多视点立体（密集重建）估算场景几何体。
• 打开场景的几何形状成三角形网格。

有说做这一切如 VisualSFM 的免费工具。你把图像和得到一个三维模型出来。 VisualSFM的部分都是开源和捆扎机项目是另一个很好的资源。不过，这将需要一些研究，如果你想拼凑自己的系统。

There are tools that do all this like VisualSFM freely available. You put in images and get a 3D model out. Parts of VisualSFM are open source and the Bundler project is another good resource. Still, it will require a bit of research if you want to piece together your own system.

如果你想看看到它背后的研究，可视化建模与一个手持相机，由Pollefeys等的。是一个良好的开端。

If you want to take a look into the research behind it, "Visual modeling with a hand-held camera" by Pollefeys et al. is a good start.
