Problems solved by technology

[0005] The second category is the equipment worn or used by the tester, which captures and recognizes the expressions and eye movements of the testee outside the body of the tester. The shortcomings of this type of equipment are very obvious
Therefore, this kind of equipment can only play the role of "performing expression" recognition, but cannot capture and analyze the subtle expressions and abnormal eye movements that represent the true state of mind of the testee

Abstract

The invention relates to an identification and prompting method and device for abnormal eyeball rotation. The device for the use of the method comprises a wearable terminal device, a cloud signal processing unit and a processing result reverse sending unit, wherein the wearable terminal device is worn on a tested person body and used for capturing and transmitting eyeball rotation data of the tested person; the cloud signal processing unit is used for calculating the eyeball rotation data of the tested person; and the processing result reverse sending unit is used for sending an abnormal eyeball rotation result, which needs to be prompted according to an instruction sent by the cloud signal process unit, to the wearable terminal device through a wireless network. Through receiving a wireless signal, the cloud signal processing unit carries out the following three stages of processing on the eyeball rotation data of the tested person: the first stage, calculating the eyeball rotation baseline data of the tested person; the second stage, capturing the eyeball rotation data in a testing question answering stage; and the third stage, comparing the eyeball rotation data of the second stage with the eyeball rotation baseline data of the first stage, carrying out relative calculation, and filtering out the abnormal eyeball rotation result.

Description

technical field [0001] The invention relates to an identification and reminder method and device for abnormal eyeball rotation, belonging to the field of intelligent facial expression identification. Background technique [0002] A microexpression is a very rapid expression that lasts only 1 / 25 to 1 / 5 of a second and expresses real emotions that a person is trying to suppress and hide. Microexpressions are very fleeting, involuntary facial expressions that humans reveal when they try to suppress or hide their true emotions. As an effective clue to identify lies, micro-expressions can be applied in security, justice, clinical and other fields. [0003] Existing wearable (portable) facial expression recognition devices are divided into two categories, one is worn on the person being tested, the other is worn on the tester, and some of them are fixed cameras for the tester, which are non-portable but have the same function as the first one. The second category is similar. ...
