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, on mobile devices, is the right and up when the device is in the natural orientation.) The data arrangement is row-major, not like OpenGL's column-major.
