本文提出了一种从一张照片创建3D模型的全自动方法。该模型由几个纹理贴图平面广告牌组成，具有典型儿童弹出式书籍插图的复杂性。我们的主要见解是，我们不是试图恢复精确的几何图形，而是统计地建模由它们在场景中的方向定义的几何图形类。我们的算法将输入图像的区域分为粗略的类别：“地面”、“天空”和“垂直”。然后，这些标签被用来使用一组简单的假设将图像剪切和折叠到弹出模型中。由于问题本身的模糊性和该方法的统计性质，该算法并不是对每一幅图像都有效。然而，对于从普通人的相册中拍摄的广泛场景来说，它的表现出人意料地好。
This paper presents a fully automatic method for creating a 3D model from a single photograph. The model is made up of several texture-mapped planar billboards and has the complexity of a typical children's pop-up book illustration. Our main insight is that instead of attempting to recover precise geometry, we statistically model geometric classes defined by their orientations in the scene. Our algorithm labels regions of the input image into coarse categories: "ground", "sky", and "vertical". These labels are then used to "cut and fold" the image into a pop-up model using a set of simple assumptions. Because of the inherent ambiguity of the problem and the statistical nature of the approach, the algorithm is not expected to work on every image. However, it performs surprisingly well for a wide range of scenes taken from a typical person's photo album.
