InputFrame Class

Description

Input frame.

It includes image, camera parameters, timestamp, camera transform matrix against world coordinate system, and tracking status,

among which, camera parameters, timestamp, camera transform matrix and tracking status are all optional, but specific algorithms may have special requirements on the input.

index

Index, an automatic incremental value, which is different for every input frame.

cameraTransform

Camera transform matrix against world coordinate system. Camera coordinate system and world coordinate system are all right-handed. For the camera coordinate system, the origin is the optical center, x-right, y-up, and z in the direction of light going into camera. (The right and up, is right and up in the camera image, which can be different from these in the natural orientation of the device.) The data arrangement is row-major, not like OpenGL’s column-major.
