Tension evaluation system for counters

Abstract

The invention discloses a tension evaluation system for counters. Thermal imaging processing and application are included. The system comprises an acquisition module, an emotion evaluation unit, a display module and a storage module; the acquisition module is hidden on a counter surface to collect facial information of a detected person; the emotion evaluation unit receives the facial information,transmitted by the acquisition module, of the detected person, analyzes breathing frequency of the detected person and judges the emotional tension degree of the detected person in combination with temperature distribution of the nose; the display module receives information, transmitted by the emotion evaluation module, of the emotional tension degree of the detected person, and displays the emotional tension degree of the detected person in the form of percentile score; and the storage module stores data of the facial information, transmitted by the acquisition module, of the detected person, and gives the emotional tension degree by the percentile score. A detection person is reminded to conduct more detailed examination or cross-examination on the detected person with tension, and a basis is provided for finding suspects with illegal intentions.

Description

technical field [0001] The invention relates to thermal imaging processing and application, in particular to a tension evaluation system for a counter. Background technique [0002] At present, the security checks at airports, entry-exit ports, etc. are mainly based on the use of detection equipment to passively search for prohibited items and the subjective judgment of inspectors. Compared with concealing prohibited items, it is more difficult to hide the nervousness of those who intend to violate the law and discipline when being interrogated in front of the counter. Nervous emotions will affect people's physiological activities, which are reflected by characteristics such as respiratory rate, facial temperature, and speech speed. It is difficult for people who have not received special training to deliberately cover up. Therefore, we propose a nervousness assessment system for the counter, which can use the thermal imager to measure the relevant characteristics of non-co...

Problems solved by technology

These methods require blood testing of the tested person or contact measurement with medical instruments, which not only cannot meet the time requirements for counter procedures, but also attract the attention of the tested person, increase the nervousness of the tested person, and affect the test result.
