Abstract
Description

[0001] The present application relates to the technical field of smart display devices, and in particular to a smart display device that facilitates facial recognition. Background Art
[0002] With the development of smart display device technology, facial recognition detection technology for smart devices has emerged. In general, smart display devices, such as mobile phones and tablets, place cameras on the edge borders in order to center the display screen, and the cameras are used to implement facial recognition detection technology. This design limits the camera's viewing angle, resulting in the inability to capture the user's complete facial features during long-term facial recognition processes, especially when the user needs to use the device at different angles. In addition, fixed-position cameras often require users to adjust their position to adapt to the camera's viewing angle, which not only affects the user experience, but also limits the accuracy of facial recognition technology and the breadth of application scenarios. Moreover, for some larger display devices, it is not convenient to adjust the facial detection viewing angle by adjusting the overall position of the device. Utility Model Content

[0026] See Figure 1 and Figure 2 As shown, Figure 1 This is a structural diagram of an intelligent display device in an embodiment of the present application. Figure 2This is a schematic diagram of the structure of a rotating image capture module in an embodiment of the present application, illustrating a smart display device that facilitates facial recognition. The smart display device includes a base 1 of the smart display device. A display screen 2 is disposed in the middle of one side of the base 1, and a frame 3 is disposed around the edge of the base 1 surrounding the display screen 2. The rotating image capture module is disposed on the frame 3 of the base 1. The rotating image capture module includes a positioning shell 4 and a rotating shaft 5. The positioning shell 4 is positioned and mounted on the frame 3. A rotating mounting groove is defined on the surface of the positioning shell 4, and the rotating shaft 5 is rotatably connected within the rotating mounting groove. With respect to the base 1, the display screen 2 is on one side of the base 1, and the positioning shell 4 is provided with a rotation mounting groove on the side of the base 1 where the display screen 2 is provided, that is, the grooved side of the rotation mounting groove on the positioning shell 4 is provided on the same side as the display screen 2 on the base 1. Furthermore, a component mounting surface 6 is provided on the axial surface of the rotating shaft 5, and the component mounting surface 6 is also located on the side of the base 1 where the display screen 2 is provided, that is, the side of the component mounting surface 6 on the axial surface of the rotating shaft 5 is provided on the same side as the display screen 2 on the base 1. An image capture lens 7 is provided on the component mounting surface 6, and the image capture lens 7 faces the outside of the rotation mounting groove and is used to capture image information data. The rotating shaft 5 can rotate relative to its own axis, thereby driving the image capture lens 7 provided on the component mounting surface 6 to move.
[0027] When implementing facial detection, the AI algorithms, software, and data required for face capture and emotion recognition are considered. Due to the difficulty of sampling data from specific angles and the limited availability of data sources, a lack of facial data samples from specific angles can lead to lower recognition accuracy. Therefore, controlling the rotating shaft 5 to rotate the image capture lens 7 to different viewing angles can satisfy the need for facial image data acquisition at specific viewing angles. In one embodiment of the present application, the image capture lens 7 is positioned within the top frame 3 of the smart display device, with the axis of the rotating shaft 5 parallel to the length of the frame 3. When the rotating shaft 5 rotates, the image capture lens 7 rotates upward or downward by 0 to 45 degrees relative to the horizontal plane of the axis of the rotating shaft 5, thereby expanding the image acquisition range of the image capture lens 7. Furthermore, to achieve more detailed and accurate image capture, at least two image capture lenses 7 are provided. During facial detection, multiple image capture lenses 7 are activated simultaneously to capture facial information images from multiple viewing angles. The specific selection and configuration of the aforementioned image capture lens 7 can be implemented with reference to existing technologies and can be modified according to actual needs. This article will not elaborate on this in detail.
[0028] Among them, the smart display device can be any electronic product with a display function, including but not limited to the following categories: televisions, laptops, desktop monitors, tablet computers, digital cameras, smart bracelets, smart glasses, car displays, industrial control equipment, medical display screens, touch interactive terminals, etc. It only needs to be able to be adaptively combined with the above-mentioned facial recognition detection technology, and the embodiments of this application do not specifically limit this. The smart display device of this application can use its rotatable image capture lens 7 to automatically capture facial images from different angles and establish a multi-angle face database. And during the entire process of collecting user facial information, facial expression videos are continuously recorded to ensure that the complete expression change process is captured. It supports long-term continuous video recording to ensure that the complete expression change process is captured, which is difficult to achieve with a fixed camera. Furthermore, the user does not need to frequently adjust the position to adapt to the camera. The system will automatically adjust the optimal shooting angle to provide the user with a more natural and comfortable interactive experience, which is particularly suitable for application scenarios that require long-term facial expression capture.
[0029] In one embodiment of the present application, the intelligent display device of the present application further includes an electronic control system disposed within the base 1, the electronic control system being used to electrically connect to the rotating image capture module, thereby controlling the rotation of the rotating shaft 5 within the image capture module and the image capture of the image capture lens 7, etc. The specific implementation structure of the electronic control system can be implemented by a system in the prior art, such as configuring an electronic control element of an information processing module for the image capture lens 7, configuring a motion control element for the rotational movement of the rotating shaft 5, and configuring a control signal transmission element between the electronic control element and the motion control element, etc. Of course, this is only one implementation method, and the specific composition of the electronic control system can be changed according to actual needs, and will not be elaborated in detail herein.
[0030] In one embodiment of the present application, the rotating image capture module further includes a rotation drive mechanism disposed between the rotating shaft 5 and the rotating mounting slot. The rotation drive mechanism is electrically connected to the electronic control system and drives the rotating shaft 5 by receiving control signals from the electronic control system. The electronic control system can control the rotation angle of the rotating shaft 5, the dwell time at each angle, the rotation speed, the directional scanning, and other specific technical effects through the rotation drive mechanism.
[0031] The specific implementation structure of the above-mentioned rotation drive mechanism can be implemented with reference to the mature electric control rotation structure in the prior art, so as to achieve precise control over the rotation of the lens viewing angle.
[0032] In one embodiment of the present application, the intelligent display device of the present application further includes an information processing module disposed within the base 1, and the information processing module is electrically connected to the electronic control system. The information processing module can feed back the image information obtained by the image capture lens 7 to the electronic control system in real time, thereby controlling the rotating shaft 5 to perform the next rotation operation based on the control signal of the electronic control system. Of course, this control logic is only one implementation method. The specific combination and control method of the information processing module can be implemented by referring to the existing technology, and will not be elaborated in this article.
[0033] In one embodiment of the present application, a fill light 8 is further provided on the component mounting surface 6 and is electrically connected to the electronic control system. The fill light 8 is positioned to the side of the image capture lens 7 as needed, and is oriented in the same direction as the image capture lens 7, to which it is adjacent. When facial detection is activated, the fill light 8 and the image capture lens 7 are activated synchronously under the control of the electronic control system. In one embodiment of the present application, two fill lights 8 are symmetrically positioned on either side of the image capture lens 7 to provide uniform fill light for the image capture lens 7.
[0034] In one embodiment of the present application, a switch signal light 9 is also provided on the component mounting surface 6 and is electrically connected to the electronic control system. The switch signal light 9 has at least two colors of light to distinguish the on / off state of the facial detection system. For example, when the switch signal light 9 displays red, the facial detection system is in the off state; when the switch signal light 9 displays green, the facial detection system is in the on state, reminding the user whether the facial detection system is operating normally and reminding the user to turn it off in time to protect personal privacy. The switch signal light 9 is located at the edge of the component mounting surface 6 to prevent its light from affecting the image protection effect of the picture capture lens 7.
[0035] In one embodiment of the present application, the above-mentioned rotation drive mechanism includes two rotating motors arranged at both ends of the rotating shaft 5, the rotating end of the rotating motor is connected to the end of the rotating shaft 5, and the fixed end of the rotating motor is fixed inside the rotating mounting groove. The rotating motors are both electrically connected to the electronic control system, and the electronic control system synchronously controls the two rotating motors to ensure that the rotating shaft 5 rotates synchronously and stably.
[0036] In one embodiment of the present application, the component mounting surface 6 is configured as a recessed surface on the axial surface of the rotating shaft 5 to prevent protruding structures such as the image capture lens 7 from colliding with the exterior and causing damage during rotation. It should be noted that the recessed degree of the component mounting surface 6 needs to ensure that the outermost ends of the protruding structures such as the image capture lens 7 do not protrude beyond the diameter of the rotating shaft 5, but it should not be too deep to avoid affecting the light collection of the image capture lens 7, that is, to avoid affecting the normal viewing angle range of the image capture lens 7.
[0037] In one embodiment of the present application, a mounting hole is provided on the frame 3 corresponding to the positioning shell 4, a snap-in groove is provided on the mounting hole, a snap-in portion cooperating with the snap-in groove is provided on the outside of the corresponding positioning shell 4, and a mounting shell 10 is provided on the outside of the mounting hole, and the mounting shell 10 is used to firmly mount the positioning shell 4 inside the snap-in groove. Among them, the snap-in groove of the mounting hole and the snap-in portion of the positioning shell 4 can both refer to the positioning and mounting matching structure settings of the prior art, and it is only necessary to ensure that the two are firmly positioned and connected, and this article does not make too many restrictions. Similarly, the mounting shell 10 is only used to assist in the positioning and installation of the positioning shell 4 and to protect the electrical circuits that may be included in the rotating picture capture module from being exposed outside the overall structure. The specific shape and positioning method of the mounting shell 10 are not too limited here.
[0038] In one embodiment of the present application, the rotating shaft 5 further includes a transparent protective cover mounted on the outside of the component mounting surface 6. This transparent protective cover protects the safety of the components on the component mounting surface 6 while ensuring that the image capture effect is not affected. The specific structure and selection of the transparent protective cover are not further specified herein; it only needs to provide the aforementioned protective effect.
[0039] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
