摘要：
A system for measuring the interpupillary distance of two eyes of a face using a device equipped with a display and a camera. For example, a guide marker (or guide markers) is displayed on a reflective display, and an image is captured using the camera when the reflection of the face is aligned with the guide marker. A stereo pair is created using the camera image and the reflection of the face on the display, and the interpupillary distance is determined by comparing the three-dimensional positions of the two eyes. The device is capable of calibration using a calibration object to detect the distance between the guide marker on the display and the camera. A facial recognition engine is employed in some cases to detect the eyes or other points on the camera image.
