Abnormal sight stop recognizing and reminding method and device

Abstract

The invention relates to an abnormal sight stop recognizing and reminding method and device. The device applied to the method includes wearable terminal equipment, a cloud signal processing unit and a processing result reverse feeding unit. The wearable terminal equipment is wore on the body of a testing staff and is used for capturing and transmitting the sight stop data of a person to be tested; the cloud signal processing unit is used for calculating the sight stop data of the person to be tested; the processing result reverse feeding unit is used for feeding an abnormal sight stop result, for reminding according to the command transmitted by the cloud signal processing unit, to the wearable terminal equipment through a wireless network; the cloud signal processing unit processes the sight stop data of the person to be tested in three steps through wireless signal receiving; in the first step, the sight stop baseline data of the tested person are calculated; in the second step, the sight stop data in a testing question answer step are captured; in the third step, the sight stop data of the second step are compared with the sight stop baseline data of the first step, relevant calculation is performed, and the abnormal sight stop result can be acquired by filtering.

Description

technical field [0001] The invention relates to a method and device for identifying and reminding abnormal line of sight parking, and belongs to the field of intelligent facial expression recognition. 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. ...

Problems solved by technology

[0005] The second category is the equipment worn or used by the tester, which shoots and recognizes the expression and line of sight of the tested person outside the tested body. 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 line of sight that represent the true state of mind of the testee.
