Ground Truth 레이블 지정

여러 신호에서 대화형 방식으로 ground truth 레이블 지정

동일한 장면을 나타내는 여러 신호에 레이블을 지정하려면 Ground Truth 레이블 지정기 앱을 사용합니다. 비디오, 이미지 시퀀스, 라이다 신호(예: 포인트 클라우드 시퀀스)에 레이블을 지정할 수 있습니다. 레이블이 지정된 ground truth를 객체 검출기나 의미론적 분할 신경망과 같은 머신러닝 모델과 딥러닝 모델의 훈련 데이터로 사용할 수 있습니다. ground truth 데이터의 레이블 지정을 자동화하려면 기본 내장된 자동화 알고리즘을 사용하거나 자체 알고리즘을 개발할 수 있습니다. 이 앱은 추가적인 시간 동기화 신호를 표시하고 사용자 지정 데이터 소스를 불러오기 위한 API도 제공합니다. 장면에 레이블 지정을 시작하려면 Ground Truth 레이블 지정 시작하기 항목을 참조하십시오.
