推荐答案
Rekognition不允许您为单个面部ID提供多个面部图像.但是，您可以上传同一个人的多张面孔，并为其赋予相同的ExternalImageId.这是您通常用于将面部匹配与您的人员数据库相关联的ID.当您的应用稍后显示要匹配的人脸时，Rekognition将返回零个或多个人脸匹配.
Rekognition does not allow you to provide multiple face images for a single face ID. But you can upload multiple faces of the same person and give them the same ExternalImageId. That's the ID that you typically use to correlate a face match to your person database. When your app later presents a face for matching, Rekognition will return zero or more face matches.
