有什么方法可以使用Python在JSON中在JSON中保存为网格的两个CAD模型之间的相似性得分？

我想获得两个JSON模型之间的相似性分数，即{x，y，z}坐标通常在CAD型号作为网格中保存时获得的坐标，以执行将它们发送到3D打印机之类的事情。

以下是两个JSON模型的子集：

模型1：

[
  { "x": -5.017247, "y": 5.285160000000001, "z": 8.08087 },
  { "x": 5.4679, "y": 5.285160000000001, "z": 8.08087 },
  { "x": -5.017247, "y": 5.285160000000001, "z": 15 },
  { "x": -5.017247, "y": 5.285160000000001, "z": 15 },
  { "x": 5.4679, "y": 5.285160000000001, "z": 8.08087 },
  { "x": 5.4679, "y": 5.285160000000001, "z": 15 },
  { "x": -5.017247, "y": 5.285160000000001, "z": -15 },
  { "x": 5.4679, "y": 5.285160000000001, "z": -15 }
]

模型2：

[
  { "x": -12.5, "y": 8.74747, "z": -7.857685 },
  { "x": -12.5, "y": -5.746591, "z": -7.857685 },
  { "x": 12.5, "y": 8.74747, "z": -7.857685 },
  { "x": 12.5, "y": 8.74747, "z": -7.857685 }
]

正如我们所看到的，模型的大小也不同。

因此，假设模型2处于正确的方向并且与模型1相同的位置，那么有什么方法可以使用Python计算这两个坐标阵列之间的相似性得分？

原文

I want to obtain a similarity score between two JSON models i.e. {x,y,z} coordinates usually obtained when CAD models are saved as meshes to do things like sending them to a 3D printer.

Following are the subsets of the two JSON Models:

Model 1:

[
  { "x": -5.017247, "y": 5.285160000000001, "z": 8.08087 },
  { "x": 5.4679, "y": 5.285160000000001, "z": 8.08087 },
  { "x": -5.017247, "y": 5.285160000000001, "z": 15 },
  { "x": -5.017247, "y": 5.285160000000001, "z": 15 },
  { "x": 5.4679, "y": 5.285160000000001, "z": 8.08087 },
  { "x": 5.4679, "y": 5.285160000000001, "z": 15 },
  { "x": -5.017247, "y": 5.285160000000001, "z": -15 },
  { "x": 5.4679, "y": 5.285160000000001, "z": -15 }
]

Model 2:

[
  { "x": -12.5, "y": 8.74747, "z": -7.857685 },
  { "x": -12.5, "y": -5.746591, "z": -7.857685 },
  { "x": 12.5, "y": 8.74747, "z": -7.857685 },
  { "x": 12.5, "y": 8.74747, "z": -7.857685 }
]

As we can see the Models also differ in size.

So, is there any way we can compute the similarity score between these two arrays of coordinates using PYTHON, assuming that model 2 is in the correct orientation and in the same position as model 1?
