3.2 The Installation Requirement of Camera
The installation diagram
The installation position selection specification of face capture camera is as follows:
1) The camera should be installed in the front of passageway and capture the positive face. The
horizontal angle of deflection had better be less than 25 °.
2) The installation of camera needs an elevation angle, which avoids the situation that the rear
face is obscured when the tandem persons go through the passageway. The vertically elevation
angle should meet the below requirement: α=15±5°.
3) It requires that the covered PD (Pupil Distance) pixels needs to be larger than 40 pixels to
distinguish the face details from the captured image. The practical width of face detection
should be less than or equal to 3 meters with 2MP camera.
4) Make sure that there is no shelter between the camera lens and the passageway.
