Description

Technical Field

[0001] This utility model relates to the field of emotion analysis equipment technology, specifically to a facial emotion monitoring and analysis device. Background Technology

[0002] Based on exercise psychophysiology, this technology can perform real-time analysis through offline video import and analysis and online camera capture. It calculates parameters such as aggression, stress, and tension of the tested person based on the frequency and amplitude of muscle vibrations in the head, face, etc. It visualizes and digitizes emotional states using different colored bars. When the threshold is exceeded, the system will take a screenshot and issue an alarm, which can quickly and effectively monitor abnormal emotions and provide early warnings to reduce the negative impact of abnormal emotions.

[0003] Existing facial emotion monitoring and analysis devices often use a single high-speed camera for image capture and analysis. However, compared to detecting muscle frequency and amplitude, the accuracy of analysis using a single high-speed camera is relatively insufficient. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a facial emotion monitoring and analysis device with relatively improved accuracy, addressing the shortcomings mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a facial emotion monitoring and analysis device, including a monitoring device body, a data exchange, a data analysis computer and a main monitoring camera. The monitoring device body includes a fixed mounting base, and a rotating disk is electrically driven on the top of the fixed mounting base. Support plates are connected to both sides of the top of the rotating disk. The main monitoring camera is rotatably mounted on the bottom of the inner side of the support plate.

[0006] The support frame plate is rotatably connected to the top of the inner side of the main frame, and a secondary frame is rotatably connected to the inner side of the main frame. The top of the main frame is connected to a first electric push rod that drives the secondary frame to adjust vertically. The secondary frame is rotatably connected to a secondary monitoring camera. A second electric push rod that drives the secondary monitoring camera to adjust horizontally is connected to one side of the secondary frame.

[0007] The outer side of the support frame plate is connected to a first motor and a second motor, which respectively drive the main monitoring camera and the main frame to rotate.

[0008] Furthermore, the rear end of the drive sub-frame is rotatably connected to the rear end of the main frame, the power end of the first electric push rod is hinged to the top of the front end of the sub-frame, the rear end of the sub-monitoring camera is rotatably connected to the rear end of the sub-frame, and the power end of the second electric push rod is hinged to one side of the front end of the sub-monitoring camera, which facilitates the adjustment of the sub-monitoring camera.

[0009] Furthermore, the main frame has a first limiting opening at the bottom front end, and the sub-frame has a first limiting rod that passes through the first limiting opening at the bottom, which facilitates stable up-and-down adjustment of the sub-frame.

[0010] Furthermore, the secondary frame has a second limiting opening on the side away from the first electric push rod, and a second limiting rod is connected to the side of the secondary monitoring camera, passing through the second limiting opening. This facilitates stable left-right adjustment of the secondary monitoring camera.

[0011] Furthermore, a support bearing is connected to the bottom of the fixed mounting base, and a rotating shaft connected to the support bearing is connected to the bottom of the rotating disk. A third motor is connected to one side of the fixed mounting base, and a gear is connected to the power end of the third motor. An annular rack that meshes with the gear is connected to the outer bottom of the rotating disk, which facilitates the rotation of the rotating disk.

[0012] Furthermore, a limiting ring frame is connected to the bottom of the fixed mounting base, and a limiting ring block that matches the limiting ring frame is connected to the bottom of the rotating disk, which facilitates the stable rotation of the rotating disk.

[0013] The advantages of this facial emotion monitoring and analysis device compared with the prior art are as follows: This device uses a main monitoring camera to anchor and monitor the subject, and then uses an adjustable secondary monitoring camera on the top to capture the subject's subtle movements, thereby maximizing the facial emotion monitoring and analysis of the subject.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Combined with appendix Figure 1-3 A facial emotion monitoring and analysis device includes a monitoring device body 1, a data exchange 2, a data analysis computer 3, and a main monitoring camera 7. The monitoring device body 1 includes a fixed mounting base 4. A rotating disk 5 is electrically driven at the top of the fixed mounting base 4. A support bearing 23 is connected to the bottom of the fixed mounting base 4. A rotating shaft 22 connected to the support bearing 23 is connected to the bottom of the rotating disk 5. A third motor 19 is connected to one side of the fixed mounting base 4. A gear 20 is connected to the power end of the third motor 19. The rotating disk 5 has an annular rack 21 connected to the outer bottom of the rotating disk 5, which meshes with the gear 20. The gear 20 is driven to rotate by the third motor 19. The annular rack 21 can stably drive the rotating disk 5 to rotate. The bottom of the fixed mounting base 4 is connected to a limiting ring frame 25. The bottom of the rotating disk 5 is connected to a limiting ring block 24 that cooperates with the limiting ring frame 25. The rotating shaft 22 and the support bearing 23 can ensure the smooth rotation of the rotating disk 5. The limiting ring frame 25 and the limiting ring block 24 can ensure the stable rotation of the rotating disk 5.

[0020] The rotating disc 5 has support plates 6 connected to both sides of its top. The main monitoring camera 7 is rotatably mounted on the bottom inner side of the support plate 6. The top inner side of the support plate 6 is rotatably connected to a main frame 9. The inner side of the main frame 9 is rotatably connected to a secondary frame 11. The top of the main frame 9 is connected to a first electric push rod 12 that drives the secondary frame 11 to adjust vertically. The inner side of the secondary frame 11 is rotatably connected to a secondary monitoring camera 13. One side of the secondary frame 11 is connected to a second electric push rod 14 that drives the secondary monitoring camera 13 to adjust horizontally. The first electric push rod 12 and the second electric push rod 14 need to be fast electric push rods because the human face moves relatively quickly. If faster accuracy is required, the electric push rods can be replaced with pneumatic push rods, but corresponding air pumps, air pipes, and three-phase valves need to be installed. This is a common existing technology for pneumatic push rods, so it will not be described in detail. The rear end of the driving secondary frame 11 is rotatably connected to the rear end of the inner side of the main frame 9. The power end of the first electric push rod 12 is connected to the secondary frame 1. The front end is hinged at the top. The rear end of the secondary monitoring camera 13 is rotatably connected to the rear end of the secondary frame 11. The power end of the second electric push rod 14 is hinged to one side of the front end of the secondary monitoring camera 13. The outer side of the support plate 6 is connected to a first motor 8 and a second motor 10 that drive the main monitoring camera 7 and the main frame 9 to rotate respectively. In actual testing, the main monitoring camera 7 and the secondary monitoring camera 13 are first moved to a suitable angle by rotating the disc 5 in conjunction with the first motor 8 and the second motor 10. The main monitoring camera 7 and the secondary monitoring camera 13 track the face synchronously. The tracking system is implemented by a microcontroller in conjunction with the rotation drive motor. This tracking system is a common existing system, so it will not be described in detail. Then, the main monitoring camera 7 identifies and tracks the face as the basic anchor. Then, the first electric push rod 12 and the second electric push rod 14 are used to adjust the horizontal and vertical movement of the secondary monitoring camera 13 to track the slight shaking of the person being identified. By combining the two, the subtle facial emotions of the person being identified can be accurately identified for monitoring.

[0021] The main frame 9 has a first limiting opening 15 at its bottom front end. The sub-frame 11 has a first limiting rod 16 that passes through the first limiting opening 15 at its bottom. The sub-frame 11 has a second limiting opening 17 on the side away from the first electric push rod 12. The sub-monitoring camera 13 has a second limiting rod 18 that passes through the second limiting opening 17 on its side. By using the first limiting rod 16 and the second limiting rod 18 in conjunction with the first limiting opening 15 and the second limiting opening 17, precise and stable adjustment can be ensured. In actual production, an outer shell structure can be produced to cover the support frame plate 6 and the internal structure for aesthetic purposes, but a transparent glass sheet corresponding to the camera must be installed.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
