ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONFigure 26: Pose angle set is with respect to the frontal view of the subjecta b c d e f gFigure 27: Examples of pose angles and their encodings.The pose angles (Y, P, R) of (a) – (g) in Figure 27 are given by (0, 0, 0), (+45, 0, 0), (-45, 0, 0),(0, -45, 0), (0, +45, 0), (0, 0, -45), and (0, 0, +45), respectively. (See also Section E.7.3 Theorder of rotation through pose angles)The uncertainty in the pose angles is given by the range 0 to 90, inclusive. It shall denoteapproximately a maximum value of possible deviation in the measurement of the pose. Thisshall correspond to a two standard deviation confidence interval.The encoding of angles is in ASCII format, with the minus sign “-“ used to denote a negativevalue and the plus “+” sign optionally used to denote a positive value. Pose angle uncertaintyangles always are positive.May, 2013 DRAFT VERSION UPDATE 2013 Page 481
ANSI/NIST-ITL 1-2011 - UPDATE 2013 DRAFT VERSIONE.7.2 Subject Pose (POS) and subject pose angles (SPA)One of either the POS or SPA fields shall be used to denote pose angles.The code values in Field 10.020: Subject pose / POS of “F”, “R”, and “L” can be used forimages in which the Pitch and Roll angles are 0 and the Yaw angle is 0, 90, and -90respectively. (The sign of the Yaw angle in the previous sentence corresponds to the field10.020 where a right profile is when the subject is facing left).Field 10.025: Subject pose angles / SPA can be used for the above poses and shall be used forall other angled poses. Field 10.020: Subject pose / POS shall then be of type code “D”, fordetermined 3D pose, instructing the user to use Field 10.025: Subject pose angles / SPA asthe reference for pose angles. (For example, a ¾ profile capture would require a POS fieldentry of “D” with the angle specified for SPA.)A frontal view consists of a face with a Yaw, Pitch, and Roll angles of zero. Field 10.025:Subject pose angles / SPA values shall be recorded as (0,0,0).A full profile view consists of a face with a Yaw pose angle of ±90 degrees, and with Pitch andRoll angles of zero. Field 10.025: Subject pose angles / SPA values shall be recorded as(90,0,0), subject facing left (right profile), and (-90,0,0), subject facing right (left profile). Forfull profile photographs, the ear facing the camera should be visible, pushing the hair back tothe extent possible. For full profile images, the entire body shall be rotated with the head.A half profile view consists of a face with a Yaw pose angle of ±45 degrees, and with Pitch andRoll angles of zero. Field 10.025: Subject pose angles / SPA values shall be recorded as(45,0,0), subject facing left, and (-45,0,0), subject facing right. For half profile, the orientationof the head is rotated 45 degrees to half profile; the rotation of the body is recommended, butnot required. Care should be taken to prevent the subject from keeping the head fixed whilechanging only the gaze. SAP 50/51 records may optionally include ¾ profile views, with aYaw pose angle of ±67.5 degrees, and with Pitch and Roll angles of zero. Subject pose angle(SPA) values shall be recorded as (67.5,0,0), subject facing left, and (-67.5,0,0), subject facingright. In all cases, the uncertainty in the Yaw pose angle determination shall be less than 5degrees of the frontal photograph, and 10 degrees in the non-frontal photographs. Uncertaintyin the Pitch and Roll angles shall be less than 5 degrees.E.7.3 The order of rotation through pose anglesAs order of the successive rotation around the different axes does matter, the encoded rotationangle shall correspond to an order of execution starting from the frontal view. This order shallbe given by Roll (about the front axis), then Pitch (about the horizontal axis) and finally Yaw(about the vertical axis). The (first executed) Roll transformation shall therefore always be inthe image (x, y) plane. Examples are shown in Figure 28. From the point of view of executinga transformation from the observed view to a frontal view, the transformation order shalltherefore be Yaw, Pitch, and then Roll. The encoded angle is from the frontal view to theobserved view. The pose angles have an origin of coordinate system at the nose tip. Figures(a)-(c) show three successive rotation steps to achieve the pose angles (Y, P, R) of (-45, -30,+45). Figures (d)-(f) show three successive rotation steps to achieve the pose angles (-30, +20,482
