*1. The detection and estimation accuracy will fall when outside the specified angle range.

Note that being within range indicated above does not always guarantee successful detection.

*2. “Up direction 15°” indicates that the camera is looking up to the target from a 15° downward angle and “Down direction -30°”

indicates that the camera is looking down to the target from a 30° upward angle.

*3. This indicates all the directions to the left and right of the human body.

*4. This is the angle when facing the camera, regardless of the face direction angle.
