Mediapipe facemesh 顶点映射

我正尝试在个人项目的自定义图形引擎中使用 Google 的 Mediapipe 面部网格。我发现有一张人脸网格图片表示从地标索引到人脸网格位置的映射。

但是,总共有 486 个地标,因此手动找出所有三角形的地标需要一段时间。是否有可用于从中加载顶点映射的顶点映射文件?

类似于:

[
[ 0, 267, 164],
[ 0, 164, 37],
[ 0, 37, 72],
...
]

最佳答案

所以我在 Mediapipe 的源代码中找到了这个。 https://github.com/google/mediapipe/blob/master/mediapipe/python/solutions/face_mesh_connections.py代码中的FACEMESH_TESSELATION frozenset定义了所有点之间的点对点连接对。但是Mediapipe提供的Mediapipe facemeshconnection pairs和图中的不一样。图片中的一些连接在代码中没有定义,代码中的一些连接在图片中没有定义。尽管如此,它对我的​​应用程序来说已经足够好了,所以我编写了一个简单的程序来从中生成顶点元组。结果在给定的 json 字符串中。如果对您有帮助,欢迎您复制。
