Mediapipe facemesh 顶点映射
Mediapipe facemesh vertices mapping
我正尝试在个人项目的自定义图形引擎中使用 Google 的 Mediapipe 面网格。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。 enter image description here
不过,总共有486个地标,所以手动算出所有三角形的地标需要一些时间。是否有我可以用来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],
...
]
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_TESSELATIONfrozenset定义了所有点之间的点对点连接对。但是连接对和Mediapipe提供的图片不一样。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。对你有帮助欢迎转载

我遇到(没有双关语意)同样的问题,发现 mediapipe/mediapipe/modules/face_geometry/data/ 文件夹包含可用的参考数据。最后,最有效的方法是使用 geometry_pipeline_metadata_landmarks.pbtxt 并对 index_buffer 条目进行正则表达式(即替换“index_buffer:”并在数字之间添加逗号。)
这产生了一个匹配的索引缓冲区。
(还有一个规范的 .obj 文件,但使用这些索引并没有给我一个完美的网格)
我正尝试在个人项目的自定义图形引擎中使用 Google 的 Mediapipe 面网格。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。 enter image description here
不过,总共有486个地标,所以手动算出所有三角形的地标需要一些时间。是否有我可以用来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],
...
]
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_TESSELATIONfrozenset定义了所有点之间的点对点连接对。但是连接对和Mediapipe提供的图片

我遇到(没有双关语意)同样的问题,发现 mediapipe/mediapipe/modules/face_geometry/data/ 文件夹包含可用的参考数据。最后,最有效的方法是使用 geometry_pipeline_metadata_landmarks.pbtxt 并对 index_buffer 条目进行正则表达式(即替换“index_buffer:”并在数字之间添加逗号。) 这产生了一个匹配的索引缓冲区。
(还有一个规范的 .obj 文件,但使用这些索引并没有给我一个完美的网格)
