SYSTEM FOR THE MEASUREMENT OF THE INTERPUPILLARY DISTANCE USING A DEVICE EQUIPPED WITH A DISPLAY AND A CAMERA

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.

1. A method of determining a distance on a human body using an electronic device, the method comprising:
displaying at least one guide marker on a display, the display having a reflective surface; capturing an image via a camera associated with the display, the image including two points on a body, wherein when the image is captured a reflection of the two points is aligned with the at least one guide marker; determining a three-dimensional position of each point based on a stereo pair, the stereo pair including the image and the reflection of the two points aligned with the at least one guide marker; and calculating the distance between the two points by comparing the three-dimensional positions of each point.
