Description

Technical Field

[0001] The utility model relates to the technical field of micro-expression analysis and recognition, in particular to an emotion recognition device based on micro-expression analysis. Background Art

[0002] Micro-expressions are short facial expressions that people make involuntarily in certain high-intensity environments while trying to hide. Micro-expressions can last as short as 1 / 25 second. Although a subconscious expression may only last for a moment, it sometimes expresses the opposite emotion. Micro-expressions are not only related to facial movements, but also body movements and sounds are important indicators of micro-expressions. Micro-expressions last for a short time, and the frequency and amplitude of their occurrence are very low. Ordinary people are not very good at recognizing them just by observing with the naked eye. In the experiment, only 10% of people noticed it. Compared with the expressions that people consciously make, "micro-expressions" can better reflect people's true feelings and motivations. How to improve the efficiency of capturing micro-expressions and enhance the ability to recognize micro-expressions is a difficult problem that needs to be solved.

[0003] When collecting micro-expressions, light conditions are one of the important factors. The machine vision light source directly affects the quality of the image and may even reduce the accuracy of intelligent analysis. How to reduce and improve the adverse effects of light on the image is an urgent problem to be solved. In the prior art, the image acquisition device can be rotated to improve the light, but it cannot achieve good results in an environment with dark surroundings.

[0004] The existing Chinese patent with authorization announcement number (CN219590852U) discloses an emotion recognition device based on micro-expression analysis. This utility model can realize intelligent analysis of micro-expression collection under optimal lighting conditions by setting up a fill light, an electric telescopic column and a photosensitive sensor. A mounting column is installed on the other side of the top of the mounting seat, and a lighting board is installed on the top of the mounting column through an electric rotating shaft, so that the camera can capture micro-expressions of the face more clearly; however, the angle of the lighting board set in this utility model is not convenient to adjust. During use, it is difficult to quickly adjust the reflection angle of the lighting board, which affects the fill light effect.

[0005] To solve the above problems, we propose an emotion recognition device based on micro-expression analysis to solve the above problems. Utility Model Content

[0027] Among them, the main camera 9 can take a frontal photo of the user's face, and the two groups of auxiliary cameras 12 can take photos of the user's face from both sides, thereby increasing the area for photographing the user's face, and then transmitting the captured pictures to the micro-expression analysis system for analysis, which can effectively improve the accuracy of micro-expression analysis.

[0028] In addition, a first telescopic rod 6 is provided in the middle of the bottom end of the main camera 9, and a second telescopic rod 11 is provided in the middle of the bottom end of the auxiliary camera 12. The height of the main camera 9 and the auxiliary camera 12 can be raised and lowered by the first telescopic rod 6 and the second telescopic rod 11, so that the recognition device of the present invention can be suitable for users of different heights.

[0029] An adjustment component is provided in the middle of the bottom end of the fill light panel 13, including a turntable 15, which is driven by a motor and located in the middle of the bottom end of the fill light panel 13.

A cylinder 17 is movably connected to one side of the upper end of the turntable 15, and the output end of the cylinder 17 is movably connected to the fill light panel 13.

[0030] The fill light plate 13 plays a role of fill light, and by rotating the turntable 15, the fill light plate 13 can be driven to rotate, and then the cylinder 17 is started to push the fill light plate 13, so as to facilitate the rapid adjustment of the angle of the fill light plate 13.

[0031] A support base 3 is provided in the middle of the bottom end of the main camera 9, and a photosensitive sensor 5 is provided in the middle of the upper end of the support base 3. The photosensitive sensor 5 is located in the middle of the bottom end of the main camera 9. The photosensitive sensor 5 can sense the brightness of the light.
