Embodiment 1

[0034] See figure 1 , which shows a flow chart of an embodiment of the method for quickly establishing the forward coordinates of the face based on face recognition in the present invention. As shown in the figure, the method for quickly establishing the forward coordinates of the human face includes the following steps:

[0035] Step S101, using a face recognition program to identify the face points represented by two-dimensional feature points of the current face image;

[0036] Step S102 finds at least two face points parallel to the horizontal direction of the face among the face points and performs direction vector calculation to construct a first direction vector representing the face forward coordinate system based on the origin in the X-axis direction ;

[0037] Step S103 interchanges the expression value of the direction vector representing the face forward coordinate system based on the origin in the X-axis direction to construct a second direction vector representi...

Embodiment 2

[0062] See Figure 4 , shows a functional block diagram of an embodiment of the device for quickly establishing face forward coordinates based on face recognition in the present invention. As shown in the figure, the device 200 for quickly establishing face forward coordinates includes a point recognition module 210, The first construction module 220, the second construction module 230 and the generation module 240, wherein, the point recognition module is used for using the face recognition program to identify the face points represented by two-dimensional feature points of the current face image; the first construction The module is used to find at least two face points parallel to the horizontal direction of the face in the face points and perform direction vector calculation to construct a first direction representing the face forward coordinate system based on the origin in the X-axis direction Vector; the second building block is used to exchange the expression value of ...

Abstract

The invention belongs to the technical field of face recognition, and discloses a method and a device for quickly establishing forward coordinates of a human face, a storage medium and a processor. According to the method, direction vector calculation is carried out on face points, in the horizontal direction, of a current face image recognized by using a face recognition program to construct a first direction vector representing a face forward coordinate system based on an original point in the X-axis direction; and coordinate value exchange is performed based on the direction vector in the X-axis direction to construct a second direction vector representing a face forward coordinate system based on the original point in the Y-axis direction so as to obtain a forward coordinate system ofthe face where the current face image is located. According to the method, the forward coordinate system dynamically established according to the human face can be rapidly obtained through simple operation, reference is provided for practical application, and compared with an existing human face forehead key point or feature point obtaining method, the method is rapid and simple and does not occupy extra hardware resources.

Description

technical field [0001] The invention relates to face recognition technology, in particular to a method, device, storage medium and processor for quickly establishing the forward coordinates of a face. Background technique [0002] Existing face recognition software tool development kit (Software Development Kit, i.e. SDK) can identify people's faces, and the coordinate system of the recognized human face points (i.e. feature points) is the coordinate system relative to the screen. The system is not affected by the pose and orientation of the face. Therefore, in a specific application, the unit length cannot be customized and the ratio is inconsistent, which brings a lot of inconvenience to the application. Contents of the invention [0003] technical purpose [0004] It is used to solve the problem of how to quickly establish a forward coordinate system based on the face points recognized by existing face recognition software. [0005] Technical solutions [0006] firs...
