Embodiment 1

[0024] figure 1 It is a schematic structural diagram of Embodiment 1 of the micro-expression recognition device of the present invention. Such as figure 1 As shown, the micro-expression recognition device of this embodiment may specifically include an expression collector 10 , a micro-expression recognizer 11 and a question validity analyzer 12 .

[0025] The facial expression collector 10 is used to collect the real-time stress facial expression information when the tested personnel answers the question when the tester carries out the test subject questioning stage to the tested personnel; the micro-expression recognizer 11 is connected with the facial expression collector 10, and the micro-expression recognizer 11 It is used to identify whether the real-time stress expression of the person under test is a micro-expression according to the real-time stress expression information collected by the expression collector 10 and the baseline expression information of the person un...

Embodiment 2

[0037] figure 2 It is a schematic structural diagram of Embodiment 2 of the micro-expression recognition device of the present invention. Such as figure 2 As shown, the micro-expression recognition device of this embodiment is based on the first embodiment, and the micro-expression recognition device further includes a question bank 13 and a display 14, and the test questions and baseline questions are stored in the question bank 13. Wherein the question bank 13 may specifically be stored in a memory.

[0038] The display 14 is connected with the question bank 13, and is used for displaying the test questions and baseline questions in the question bank 13, so that the tester can test the person under test. The display 14 is also respectively connected with the micro-expression recognizer 11 and the question validity analyzer 12 for displaying the recognition result of the micro-expression recognizer 11 and the first question validity of the current question determined by t...

Embodiment 3

[0055] image 3 It is a schematic structural diagram of Embodiment 3 of the micro-expression recognition device of the present invention. On the basis of Embodiments 1 and 2, in order to further improve the question optimization association of the micro-expression recognition device, as image 3 As shown, the micro-expression recognition device in this embodiment further includes: a shape collector 15 and a shape recognizer 16 . Among them, the form collector 15 is connected with the form recognizer 16 , and the form recognizer 16 is connected with the question validity analyzer 12 . The shape collector 15 is used to collect the shape of the tester during the questioning process, and send the collected result to the shape recognizer 16 . The shape recognizer 16 receives the collection result sent by the shape collector 15 and performs recognition, so as to obtain a shape recognition result. The form recognizer 16 sends the form recognition result to the question validity an...

Abstract

The present invention provides a micro-expression identification device and method. The device comprises an expression collector, a micro-expression identification device and a questioning validity analyzer. The expression collector is configured in the test title questioning stage of a tested person by a tester and collects the real-time stress expression information when the tested person is answering the questions; the micro-expression identification device is connected with the expression collector and is configured to identify whether the tested person's real-time stress expression is the micro expression or not according to the real-time stress expression information and the tested person's base line expression information; and the questioning validity analyzer is connected with the micro-expression identification device and is configured to determine the questioning validity of the questioning test according to the identification result of the micro-expression identification device. The present invention further provides a micro-expression identification method corresponding to the micro-expression identification device. According to the invention, the complexity of the micro-expression identification may be greatly reduced, and the efficiency of micro-expression detection is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent electronic equipment, in particular to a micro-expression recognition device and method. Background technique [0002] Facial expressions are the information expressed by people's real psychological activities or emotions projected onto the face. For example, when they are happy, they will show a smile with the corners of their mouths upturned, when they are surprised, they will show enlarged eyes, and when they are scared, they will show a smile. A series of tension or discomfort in the face. These are normal mental activities or emotional responses. In the normal situation where there is no psychological confrontation, the duration and degree of expression of facial expressions can be captured and understood relatively accurately. Micro-movements in facial expressions (referred to as "micro-expressions") are actually manifestations of real mental activities or emotions, but the duration of...
