Azure认知服务-面部API响应:保留字段还是错误?

[英]Azure Cognitive Services - Face API Response: Reserved Fields or Bugs?

在Azure Cognitive Services Face API(请参阅例如https://azure.microsoft.com/zh-cn/services/cognitive-services/face )中,以下响应字段似乎从未触发:

  1. headPose:pitch(保留字段)
  2. foreheadOccluded
  3. eyeOccluded

我是在滥用这些功能,还是有针对它们的计划,或者没有计划激活它们?

如果您在此处查看API文档:

  • 对于headPose ,它说:

编辑13/06/2019:医生说

HeadPose的音高值是一个保留字段,将始终返回0

现在更改为:

headPose:面向面部的3-D滚动/偏航/俯仰角度。

  • 对于foreheadOccluded值,我在以下测试中成功获得了true值,其中头上有一个盖帽(对不起,该示例,没有很快找到其他东西!):
