enum DJIActiveTrackCannotConfirmReasontypedef NS_ENUM (NSInteger , DJIActiveTrackCannotConfirmReason)
Header: DJIActiveTrackMission.h
Description:
The reason why user is not allowed to confirm the current target.
Enum Members:
None. The target is unstable. The target position is too high. There is an obstacle between the aircraft and the target that is blocking the target. The gimbal's attitude is pointing to the ground. The target is too far away from the aircraft. The target is too close to the aircraft. The altitude of the aircraft is too high. The altitude of the aircraft is too low. The obstacle vision sensor has errors. Unknown.
enum DJIActiveTrackTargetTypetypedef NS_ENUM (NSInteger , DJIActiveTrackTargetType)
Header: DJIActiveTrackMission.h
Description:
The type of ActiveTrack target.
Enum Members:
The ActiveTrack target is a human being. The ActiveTrack target is a car. The ActiveTrack target is a van. The ActiveTrack target is a bike. The ActiveTrack target is a boat. The aircraft cannot recognize the target type.
enum DJIActiveTrackTargetStatetypedef NS_ENUM (NSInteger , DJIActiveTrackTargetState)
Header: DJIActiveTrackMission.h
Description:
The state of the target being tracked by the aircraft.
Enum Members:
The aircraft has recognized the target but the user is not allowed to confirm the target. Check cannotConfirmReason The aircraft has recognized the target and is waiting for user's confirmation. If this state, the aircraft will hover in the current position while the camera is tracking the target (by rotating aircraft's yaw or gimbal's altitude). If user confirms the target, the aircraft will start to following the movement of the target. The aircraft has recognized the target with high confidence. The ActiveTrack Mission is tracking a target with low confidence. This is only an indication that either the aircraft will soon ask for confirmation that the target is correct, or may loose tracking the target entirely if confidence doesn't improve. Unknown.
