Description

Technical Field

[0001] The utility model relates to the field of billboard devices, in particular to an interactive billboard based on gesture recognition. Background Art

[0002] In commercial and public spaces in modern cities, advertising screens are widely used as a medium for information dissemination. However, most traditional advertising screens are limited to displaying static images or videos and lack actual interaction with the audience, which limits the advertising effect and makes it difficult to attract the continued attention of pedestrians. With the development of technology and the improvement of digitalization, people have higher expectations for the attractiveness, fun and participation of advertisements. Especially in the context of information overload, advertising forms that can attract the audience's attention and promote interaction are particularly important.

[0003] To solve this problem, the industry has begun to explore interactive solutions including sensor technology and computer vision. For example, some high-end digital signage has tried to use motion tracking and touch screen technology to increase user engagement. However, these technologies are usually expensive and have limited adaptability to the environment. For example, touch screens are easily disturbed and damaged in outdoor environments. In addition, motion tracking devices often require a large space and are complex to set up. Therefore, the existing technology still has many shortcomings. Utility Model Content

[0004] The purpose of the utility model is to provide an interactive billboard based on gesture recognition in order to overcome the defects of the above-mentioned prior art, such as low audience participation, poor publicity effect, easy interference and damage of touch and motion tracking screens, and high cost of ordinary billboards.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] An interactive billboard based on gesture recognition, comprising a fixed frame and a display screen fixed on the fixed frame, a motion image capture unit for acquiring pedestrian gestures, and a processing unit for adjusting display content of the display screen;

[0007] The motion image capturing unit and the display screen are located on the same side of the fixing frame, the motion image capturing unit is located at the edge of the fixing frame, and the motion image capturing unit and the display screen are respectively connected to the processing unit.

[0008] Preferably, the motion image capturing unit comprises a camera, and the camera is a wide-angle camera.

[0009] Preferably, there are multiple cameras, and the cameras are respectively fixed above and on both sides of the display screen.

[0010] Preferably, the camera is integrated with an infrared sensor or a depth sensor.

[0011] Preferably, a waterproof and dustproof cover and a sunshade for enabling the camera to work under various lighting conditions are provided on the outside of the camera.

[0012] Preferably, the cameras in the motion image capturing unit are arranged in an arc array or a strip array.

[0013] Preferably, a feedback unit is further provided on the fixing frame, the feedback unit is connected to the processing unit, and the feedback unit includes an audio component for playing sounds and a lighting component for creating a lighting atmosphere.

[0014] Preferably, the display screen is an LED electronic display screen or an LCD liquid crystal display.

[0015] Preferably, an anti-glare coating is provided on the outer surface of the display screen.

[0016] Preferably, a fixing platform is provided at the lower end of the fixing frame, the fixing platform is a boss structure, and the fixing frame can be detachably fixed on the fixing platform.

[0017] Compared with the prior art, the utility model has the following advantages:

[0018] (1) This solution fixes the interactive billboard in places such as shopping malls or squares through a fixed frame. When pedestrians pass in front of the billboard display screen, the motion image capture unit obtains the pedestrian's gestures and transmits the information to the processing unit. The processing unit adjusts the display content of the display screen according to the gesture information, thereby realizing the interaction between the display content and the pedestrian's gestures.

[0019] By acquiring the gestures of pedestrians and adjusting the corresponding display content on the display screen, the user experience of pedestrians when watching advertisements is improved, the novelty of the advertising content is significantly increased, and thus the publicity effect of the advertisements is effectively improved; the overall structure of the device is simple, convenient for installation, disassembly or transfer, and can be reused.

[0020] (2) Interactive billboards need to be placed in places with a large flow of people to achieve better results. Outdoor places inevitably need to consider wind and sun exposure. This solution sets a waterproof and dustproof cover and sunshade on the camera of the motion image capture unit, and sets an anti-glare coating on the outer surface of the high-definition LED or LCD display to ensure that the billboard can be used in various environments, thereby improving the practicality and applicability of the billboard.

[0021] (3) Considering that pedestrians will not maintain their gestures for a long time, the sensitivity of motion capture is required to be high. This solution sets up multiple camera groups to capture pedestrians' gestures and cooperates with corresponding infrared sensors or depth sensors to improve the accuracy and speed of gesture capture.
