Binocular Camera Design in Wall-Mounted Face Recognition Terminals
Introduction: A binocular camera in a face recognition terminal captures two slightly offset views of a face, and that geometry shapes the hardware more than most buyers expect. Two dark circles above the screen are the first thing people notice on a wall-mounted access terminal, and most of them assume the pair means the device sees in three dimensions like a scanner. Sometimes it does. Often it means something simpler: two ordinary images of the same face, taken a few centimeters apart. That distinction matters because it changes what the terminal can reasonably do at a doorway and how carefully it has to be aimed during installation. This comparison looks at how single-lens capture, ordinary dual-lens geometry, and structured light differ, then connects lens separation, field of view, and capture distance to the practical question of where a terminal goes on a wall. Why Face Terminals Often Use Two Lenses Instead of One A single lens gives a terminal exactly one version of a face....
