BS2_ScanFace

IR Face 기반 장치에서 얼굴을 스캔하고 템플릿 데이터와 이미지 데이터를 추출합니다.

함수

#include "BS_API.h"

int BS2_ScanFace(void* context, uint32_t deviceId, BS2Face* face, uint8_t erollmentThreshold, OnReadyToScan ptrReadyToScan);

파라미터

• [In] context : Context

• [In] deviceId : 장치 식별자

• [Out] face : 얼굴 데이터를 저장할 포인터

• [In] erollmentThreshold : 요구되는 얼굴 erollmentThreshold - 상세한 것은 BS2FaceConfig.enrollThreshold 참조

• [Out] ptrReadyToScan : 얼굴 스캔 준비가 완료되었을 때 호출되는 콜백 함수

반환 값

성공적으로 수행될 경우 BS_SDK_SUCCESS를 반환하고, 에러가 발생할 경우 상응하는 에러 코드를 반환합니다.
