Description
value when face picture authentication. Other percentages,
distances and angles in this table should also meet their
conditions.
Recommended Value: 14
Min. Detection Area
(Height)
When the distance between the camera and the user is long,
the parameter represents the minimum percentage of the
facial height in the total height of the recognition area.
The actual percentage should be larger than the configured
value when face picture authentication. Other percentages,
distances and angles in this table should also meet their
conditions.
Recommended Value: 12
Min. Detection Width
(Close to)
When the distance between the camera and the user is
short, the parameter represents the minimum percentage of
the facial width in the total width of the recognition area.
The actual percentage should be larger than the configured
value when face picture authentication. In this condition, the
device will not detect other parameters.
Margin (Left)
The distance from the face left side to the left margin in the
recognition area.
The actual distance should be larger than the configured
value when face picture authentication. Other percentages,
distances, and angles should also meet their conditions.
Margin (Top)
The distance from the face top side to the top margin in the
recognition area.
The actual distance should be larger than the configured
value when face picture authentication. Other percentages,
distances, and angles should also meet their conditions.
Margin (Right)
The distance from the face right side to the right margin in
the recognition area.
The actual distance should be larger than the configured
value when face picture authentication. Other percentages,
distances, and angles should also meet their conditions.
Margin (Bottom)
The distance from the face bottom side to the bottom margin
in the recognition area.
The actual distance should be larger than the configured
value when face picture authentication. Other percentages,
distances, and angles should also meet their conditions.
Pitch Angle
The maximum pitch angle when face authentication.
By default, the angle is 30°.
Yaw Angle
The maximum yaw angle when face authentication.
By default, the angle is 20°.
Pupillary Distance
The minimum resolution between two pupils when face
