将2d图像转换为3d图像的算法

Question

出于研究目的，是否有任何可以将2d图像转换为3d模型的算法？例如，将圆形变换为球形或将苹果图像变换为苹果的三维模型。简单的算法或不完美的算法也很好。如果没有，我应该研究哪些领域或领域以了解更多信息？

Answer 1

It's worth searching here http://make3d.cs.cornell.edu/code.html There are the sources of 2D-to-3D propcessing algorithm based on the conception of neural networks. This project was introduced by prof. Andrew Ng team.

Answer 2

Very funny idea, as it is obvious that there isn't enough information in a 2D image for precise 3D reconstruction. Exploiting some a priori knowledge of the real world, you can do something, but this is far-reaching.

Much simpler: see the image intensity as a depth information and you have a so-called range image, which is 3D (but the surfaces will be quite unnatural)
