Abstract

Claims (51)

1. A method for adjusting a position of an earphone, wherein the earphone is provided with a TOF (Time-of-Flight) sensor, and the method comprises:

acquiring position information of an ear using the TOF sensor, wherein the position information of the ear includes positions of points describing the ear in morphology;

determining a position of a center point of an ear canal according to the position information of the ear;

acquiring a position of a center point of the earphone; and

outputting an adjustment vector of the position of the earphone according to the position of the center point of the ear canal and the position of the center point of the earphone.

2. The method according to claim 1 , wherein acquiring the position of the center point of the earphone comprises:

determining the position of the center point of the earphone according to a position of the TOF sensor relative to the center point of the earphone.

3. The method according to claim 1 , wherein determining the position of the center point of the ear canal according to the position information of the ear comprises:

determining the position of the center point of the ear canal from the position information of the ear by using a big top heap sorting method.

4. The method according to claim 1 , further comprising:

determining a contour of the ear canal according to the position information of the ear;

acquiring a current position of the center point of the earphone after the position of the earphone is adjusted;

when the center point of the earphone is within the contour of the ear canal, stopping the adjustment of the position of the earphone; and

when the position of the center point of the earphone is not within the contour of the ear canal, acquiring a current position of the center point of the ear canal, and outputting an adjustment vector of the position of the earphone according to the current position of the center point of the ear canal and the current position of the center point of the earphone.

5. The method according to claim 4 , wherein determining the contour of the ear canal according to the position information of the ear comprises:

determining contour information of the ear according to the position information of the ear;

performing edge detection on the contour information of the ear to obtain a plurality of closed edge curves; and

determining a shortest closed edge curve in the closed edge curves as the contour of the ear canal.

6. The method according to claim 5 , wherein performing edge detection on the contour information of the ear to obtain a plurality of closed edge curves comprises:

using a Roberts edge detection operator to perform edge detection on the contour information of the ear to obtain a plurality of closed edge curves.

7. A device for adjusting a position of an earphone, wherein the earphone is provided with a TOF (Time-of-Flight) sensor, and the device comprises:

a first acquisition module for acquiring position information of an ear using the TOF sensor, wherein the position information of the ear includes positions of points describing the ear in morphology;

a first determination module for determining a position of a center point of an ear canal according to the position information of the ear;

a second acquisition module for acquiring a position of a center point of the earphone; and

a first output module for outputting an adjustment vector of the position of the earphone according to the position of the center point of the ear canal and the position of the center point of the earphone.

8. The device according to claim 7 , further comprising:

a second determination module for determining a contour of the ear canal according to the position information of the ear;

a third acquisition module for acquiring a current position of the center point of the earphone after the position of the earphone is adjusted;

a stopping module for, when the center point of the earphone is within the contour of the ear canal, stopping the adjustment of the position of the earphone; and

a second output module for, when the position of the center point of the earphone is not within the contour of the ear canal, acquiring a current position of the center point of the ear canal, and outputting an adjustment vector of the position of the earphone according to the current position of the center point of the ear canal and the current position of the center point of the earphone.
