将2D平面转换为3D模型 [英] Convert 2D planes to 3D model

问题描述

我们有一个从扇形光束角度扫描的物体的二维平面图像。一个示例在下面的图5中。我们有多个粗糙的点状平面可以扫描整个图像。

We have a multiple 2D planar image of an object scanned from a fan-beam perspective. An example is in Fig 5 below. We have multiple grainy dotted planes to scan the whole image.

这些图像的问题在于，由于扇形光束变形，它们无法直接映射到3D平面。

The issue with these images is that they cannot be directly mapped to a 3D plane due to the fan beam deformation.

是否存在可以推荐的校正算法/方法，以便这些平面可以正确地映射到3D平面并可以正确地重建对象？

Is there correction algorithms/methods that can be recommended so that these planes can be correctly mapped to 3D plane and an object can be reconstructed properly?

推荐答案

根据存储数据的方式，可能有各种方法。假设您将数据存储为点（点状虚线平面），则可以对连续平面中的相应点进行插值，从而获得整个对象的扫描。它确实要求这些点在同一帧中，因此您可能必须进行某种转换才能找到每个飞机到全局框架的参数。

Depending on how you store your data, there might be various approaches. Guessing that you store the data as points ("grainy dotted planes"), you can do an interpolation of the corresponding points in the consecutive planes and thereby get the scan of the entire object. It does require the points to be in the same frame, so you might have to do some kind of transformation to find the parameters of each plane to a global framework.

另一个步骤可能是对每个平面使用最小二乘拟合，然后将其用于将对象映射在一起。您可能会发现一些使用2d方法扫描3d对象的有用方法。希望这可以帮助。

Another procedure might be use of a least square fitting of each plane which can then be used to map together the object. You might find some helpful approaches of scanning 3d objects using 2d methods. Hope this helps.
