bool

True 是表示 如果群組已準備好預先建立臉部驗證;否則為 false。

備註

PerceptionFaceAuthenticationGroup 的所有成員預期都會調整任何設定，以完全支援臉部驗證，例如 IPerceptionFrameProvider 成員基礎裝置上的對比或曝光。 處理常式會傳回所有成員是否都準備好預先建立臉部驗證。

如果處理常式傳回 true，則在叫用與群組相關聯的 PerceptionStopFaceAuthenticationHandler 之前，所有成員預期都會維持在這個模式中。

如果處理常式傳回 false，則不會使用 IPerceptionFrameProvider () 來進行臉部驗證。
