Class InputFrame

네임스페이스

easyar

입력 프레임. 이미지, camera 파라미터, 타임스탬프, 월드 좌표계에 대한 카메라의 변환(transform), 추적 상태를 포함합니다. 여기서 camera 파라미터, 타임스탬프, 월드 좌표계에 대한 카메라의 변환, 추적 상태는 모두 선택 사항이지만, 특정 알고리즘 구성 요소는 입력에 대한 특정 요구 사항을 가질 수 있습니다.

cameraTransform

카메라가 월드 좌표계에 상대적인 변환. 이때 카메라 좌표계와 월드 좌표계 모두 오른손 좌표계이다. 카메라 좌표계의 원점은 카메라의 광학 중심이며, x축 양의 방향은 오른쪽, y축 양의 방향은 위쪽, z축 양의 방향은 빛이 카메라로 들어오는 방향이다. (여기서 오른쪽과 위쪽은 카메라 이미지에서의 오른쪽과 위쪽을 의미하며, 기기의 자연스러운 방향과 다를 수 있다.) 데이터의 배열 방식은 row-major로, OpenGL의 column-major와 반대이다.
