A method and display system for tracking and locating human faces

Abstract

The invention discloses a method for tracking and positioning faces and a display system. The method includes S0, setting a first reference line segment, a second reference line segment, a third reference line segment and a fourth reference line segment which are at least four line segments formed by a plurality of reference feature points, and setting a comparison reference point; S1, forming a first actual line segment, a second actual line segment, a third actual line segment and a fourth actual line segment which correspond to the reference line segments, and setting an actual comparison point; S2, comparing a specific ratio of the first actual line segment to the second actual line segment to a specific ratio of the first reference line segment to the second reference line segment, and judging whether the specific ratio of the first actual line segment to the second actual line segment is identical to the specific ratio of the first reference line segment to the second reference line segment or not; S3, comparing a specific ratio of the third actual line segment to the fourth actual line segment to a specific ratio of the third reference line segment to the fourth reference line segment, and judging whether the specific ratio of the third actual line segment to the fourth actual line segment is identical to the specific ratio of the third reference line segment to the fourth reference line segment or not; S4, comparing the position of the actual comparison point to the position of the comparison reference point, and judging whether the position of the actual comparison point is identical to the position of the comparison reference point or not. The method and the display system have the advantage that the faces can be accurately tracked and positioned by the aid of the method and the display system.

Description

technical field [0001] The present invention relates to the field of electronic equipment, and more specifically, relates to a method and a display system for tracking and locating a human face by adjusting the position of a display screen. Background technique [0002] The electronic device has a display screen for the user to watch, which is widely used in various terminals including notebook personal computers, desktop personal computers, all-in-one machines, etc. Only when the user is at the best viewing angle relative to the electronic device, the viewing effect It's the best. At present, when the direction of the electronic device remains unchanged and the user uses the electronic device due to some need to change the face orientation, although there is also a method to adjust the position of the display screen of the electronic device to adapt to the position of the face according to the change of the face position , but the implementation process is relatively compl...
