Embodiment 1

[0048] Please see figure 1 , figure 1 A schematic flowchart of a method for determining a learning state is provided for the embodiment of the present application. The method for determining the learning status can be applied to various scenarios where the learning status needs to be obtained. For example, the method can be applied to a series of scenarios such as classrooms and teaching plazas, which are not limited in this embodiment. Such as figure 1 As shown, the method for determining the learning state includes:

[0049]S101. Acquire a facial image.

[0050] In this embodiment, the facial image may be the facial image of the user, that is, the facial image of the object in the observed learning state, wherein the observed object in the learning state is called the user.

[0051] In this embodiment, the face image is a learner's face image and face image data.

[0052] In this embodiment, the facial image may be acquired through a camera array.

[0053] In this embo...

Embodiment 2

[0082] Please see figure 2 , figure 2 It is a schematic flowchart of another method for determining a learning state provided in the embodiment of the present application. figure 2 The described method for determining the learning state is based on figure 1 A modification of the described method for determining the learning state is obtained. like figure 2 As shown, the method for determining the learning state includes:

[0083] S201. Acquire a facial image.

[0084] In this embodiment, the facial image may be the facial image of the user, that is, the facial image of the object in the observed learning state, wherein the observed object in the learning state is called the user.

[0085] In this embodiment, the face image is a learner's face image and face image data.

[0086] In this embodiment, the facial image may be acquired through a camera array.

[0087] In this embodiment, there may be more than one facial image. Specifically, the facial image may be for mu...

Embodiment 3

[0119] Please see image 3 , image 3 It is a schematic structural diagram of an apparatus for determining a learning state provided in an embodiment of the present application. Wherein, the determining device of the learning state includes:

[0120] An acquiring unit 310, configured to acquire facial images.

[0121] The extracting unit 320 is used to obtain the facial quantitative features corresponding to the facial image in the facial image.

[0122] The matching unit 330 is configured to match facial expressions corresponding to facial quantitative features in a preset expression database.

[0123] The determining unit 340 is configured to determine a learning state corresponding to the facial expression according to the facial expression.

[0124] In this embodiment, the device for determining the learning state may be connected to a video converging device, and the video converging device is connected to the camera array and gathers images acquired by the camera arr...

Abstract

The embodiment of the invention provides a learning state determination method and a learning state determination device, and relates to the technical field of education. The method comprises the following steps: obtaining a face image; obtaining a face quantization feature corresponding to the face image from the face image; matching facial expressions corresponding to the facial quantitative features in a preset expression database; and determining a learning state corresponding to the facial expression according to the facial expression. By implementing the embodiment, the determination time can be shortened, the determination speed can be increased, the determination cost can be reduced, and the determination objectivity can be enhanced.

Description

technical field [0001] The present application relates to the field of educational technology, in particular, to a method and device for determining a learning state. Background technique [0002] At present, the quality of teaching is an important part of measuring the level of running a school, and the learning status of learners is an important indicator reflecting the quality of teaching. Therefore, more and more teachers hope to obtain accurate learning status of learners. However, in practice, it is found that the current learning status of learners is usually determined by manual discrimination, and the current method has the disadvantages of long determination time, slow determination speed, high determination cost and strong subjectivity. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a method and device for determining a learning state, which can reduce the determination time, increase the determination ...
