Detailed Description
In order to more clearly explain the present application, the present application is further described below with reference to the embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not intended to limit the scope of the present application.
As shown in fig. 1, one embodiment of the present application provides a display apparatus 10 comprising a controller 12, at least one image collector 11, and at least one light control glass 13 positioned in at least one display orientation;
the image collector 11 is used for collecting peripheral images of the display device;
and the controller 12 is used for detecting behaviors of the peripheral images of the display device, and controlling the dimming glass 13 to be in a dark state when illegal behaviors such as photographing are detected, namely, the light transmittance of the dimming glass 13 is reduced to enable the dimming glass to be opaque, so that the exhibits displayed by the display device 10 are shielded, and the protection of the exhibits is realized.
The display device 10 provided by the embodiment of the application, the monitoring image collected in real time is subjected to behavior detection to prejudge whether illegal behaviors such as photographing occur, so that threat early warning is accurately performed, and then the illegal behaviors such as photographing for the exhibits, confidential information and the like are actively intercepted in time by changing the bright state of the dimming glass 13 into the dark state when the illegal behaviors are prejudged to occur through behavior detection, so that active protection for the cultural relics, the copyright or the confidential information is realized, and the display device is suitable for various places such as museums, exhibition halls, customs and frontier inspection halls.
It can be understood that, in this embodiment, when the illegal action such as taking a picture is not detected, the controller 12 controls the light control glass 13 to keep a bright state, that is, the light transmittance of the light control glass 13 is increased to make it transparent, so as to normally display the exhibit; after the controller 12 controls the light control glass 13 to be in the dark state, if the illegal action such as photographing cannot be detected through subsequent action detection, it indicates that the detected illegal action such as photographing disappears, and the controller 12 controls the light control glass 13 to return to the bright state.
In some embodiments, display 10 includes at least two pieces of light control glass 13 respectively positioned in at least two display directions and at least two image collectors 11 respectively used for collecting peripheral images of the display in the at least two display directions;
the controller 12 is configured to perform behavior detection on the peripheral images of the display device in the at least two directions, and when an illegal behavior such as taking a picture is detected, control the dimming glass 13 in the direction where the peripheral image of the display device corresponding to the illegal behavior such as taking a picture is located to be in a dark state.
Therefore, the display device 10 provided in the first aspect of the present application can actively protect a direction in which there is a threat of illegal behavior such as taking a picture, without affecting the display in the direction without the threat.
For example, as shown in fig. 2, the display device 10 is a display cabinet for displaying cultural relics such as blue and white porcelain bottles in a museum, visitors can visit the blue and white porcelain bottles placed in the display device 10 from the front, the rear, the left and the right, and the display cabinet has four individually controllable light control glasses 13 in the front, the rear, the left and the right and four image collectors 11 for respectively collecting images around the display device in the front, the rear, the left and the right. If the controller 12 does not detect violation behaviors such as photographing when performing behavior detection on the peripheral images of the display device in the four directions, controlling the four pieces of dimming glass 13 in the four directions to keep the bright state as shown in fig. 2; if the controller 12 detects that there is an illegal behavior such as taking a picture in the front when detecting the behavior of the peripheral images of the display device in four directions, the front light control glass 13 is controlled to be in a dark state, and the other three light control glasses 13 are still kept in a bright state; if the controller 12 detects that there is an illegal behavior such as photographing in all four directions when performing behavior detection on the peripheral images of the display device in all four directions, the light control glass 13 in all four directions is controlled to be in a dark state, as shown in fig. 3.
For another example, for a display case with four display directions as shown in fig. 2, a wide-angle camera such as a 360 ° camera may be used as the image collector 11 to collect the images around the display device. In this case, the four-direction light control glass 13 may be controlled individually or in a unified manner, and the control logic may be: if the controller 12 detects illegal behaviors such as photographing when detecting the behavior of the images around the wide-angle camera collecting and displaying device, the four-direction dimming glass 13 is controlled to be in a dark state.
For another example, when the display device 10 is a showcase for displaying cultural exhibits such as blue-white porcelain bottles in a museum, the display device may include only three display directions (for example, one side of the showcase is close to a wall, and if the rear side is close to the wall, the display directions are front, left, and right, the showcase has three independently controllable light control glasses 13 in front, left, and right), or two display directions (for example, two sides are close to a wall, and if the rear side is close to the wall, the display directions are front and left, the showcase has two independently controllable light control glasses 13 in front and left), and in addition, the upper side may also be used as the display direction. If display 10 is a display frame for a museum for displaying cultural displays such as oil paintings, it typically includes only one display orientation. The above is merely an example of the corresponding relationship between the display direction and the light control glass 13 when the display device 10 is a showcase in a museum, and should not be construed as a limitation to the present application.
In some embodiments, the privacy glass 13 is a liquid crystal privacy glass.
The bright state/dark state switching response speed of the liquid crystal dimming glass can reach millisecond level and the switching reliability is high, so that the timeliness and the reliability of protecting the exhibit and confidential information through shielding can be guaranteed.
In a specific example, the light control glass 13 adopted in the present embodiment is a liquid crystal light control glass, and the controller 12 can be used to output an electrical signal to adjust the light transmittance of the liquid crystal layer, so as to display or shield the exhibit. The light transmittance of the liquid crystal dimming glass in a bright state can be stabilized to be about 85%, and the liquid crystal dimming glass is uniform in light transmittance and can well display exhibits inside the liquid crystal dimming glass; the light transmittance of the liquid crystal dimming glass is close to 0 in a dark state, and the liquid crystal dimming glass is in a completely black shielding state, so that the display can be well protected. The response speed of the liquid crystal dimming glass is millisecond-level, and the action of taking the photographing device by a tourist for photographing belongs to second-level, so that the millisecond-level bright state/dark state switching response speed can meet the time requirement for realizing real-time shielding.
In a specific example, as shown in fig. 4 and 5, the liquid crystal dimming glass includes two glass substrates 131 disposed opposite to each other, two transparent electrode layers 132 disposed inside the two glass substrates 131, and a liquid crystal layer 133 disposed inside the two transparent electrode layers 132, wherein the liquid crystal layer 133 includes a plurality of liquid crystal molecules arranged in an array, an electric field effect of twisted nematic of the liquid crystal molecules can be caused by adjusting an electric field generated by the two transparent electrode layers 132, and light transmittance of the liquid crystal molecules can be changed by adjusting a voltage of the two transparent electrode layers 132. As shown in fig. 4, when the controller 12 outputs a voltage signal to the two transparent electrode layers 132, the liquid crystal molecules are driven by the electric field to generate alignment change, and the light can penetrate through the liquid crystal light-adjusting glass, and the liquid crystal light-adjusting glass is transparent and bright, so that the exhibited item can be well displayed. As shown in fig. 5, when the controller 12 stops outputting the voltage signal to the two transparent electrode layers 132, the liquid crystal molecules are in a disordered state, the light cannot penetrate through the liquid crystal light-adjusting glass, and the liquid crystal light-adjusting glass is completely opaque and is in a dark state, so as to shield the exhibit and protect the exhibit well.
Besides the liquid crystal light control glass 13 belonging to the electric control mode, the light control glass 13 may also adopt a light control glass 13 of a voltage control mode or the like.
In some embodiments, the display apparatus 10 further includes a display 14 and a voice player 15, and the controller 12 is further configured to control the display 14 to display a prompt message and control the voice player 15 to report the prompt message when an illegal action such as taking a picture is detected.
Thus, while performing active protection, it is possible to prompt the relevant person such as a guest to stop taking a picture or other illegal action by various means such as displaying characters (for example, displaying "no taking a picture, please comply with regulations"), displaying graphics (for example, displaying a prohibition indication of a camera image), and voice broadcasting (for example, playing "no taking a picture, please comply with regulations" recording "). In addition, the worker may be prompted to pay the necessary attention.
In a specific example, when detecting an illegal action such as taking a picture, the controller 12 may further display, through the display, a peripheral image of the display device that identifies the illegal action such as a photo action of a visitor, so as to further enhance the prompting effect.
In some embodiments, the display 14 is a transparent display 14 disposed on at least a partial area outside the privacy glass 13. Thus, the effect of the prompt can be improved, for example, the tourist who intends to photograph the exhibit can directly see the displayed prompt information by looking at the exhibit through the camera lens.
In some embodiments, the controller 12 is a micro control unit MCU; image collector 11 is a high definition camera, and its parameter sets are: 1080p resolution, 32G memory, 8bit wide pixel and 3.3mm focal length; the monitoring angle is adjustable. The image collector 11 and the controller 12 may be connected in a wired or wireless manner, for example, connected to the high-definition camera and the MCU through a network cable, and the network cable is also used to supply power to the high-definition camera while transmitting image data. The network cable has the advantages of high transmission rate, long transmission distance, high cost performance and the like, in the example, the network cable works in a gigabit network mode, the effective data transmission bandwidth of the network reaches more than 400Mb/s, the frame rate can reach 23 frames/s, and the image transmission requirement is met.
Taking the display device 10 as the showcase shown in fig. 2 as an example, the arrangement manner of the image collector 11 such as a camera is shown in fig. 6: the camera sets up at the showcase top, and image acquisition's surveillance content is the motion capture, and consequently, the focus of camera selects 3.3 millimeters, and when the camera focus was 3.3 millimeters, its monitoring angle was 80, and monitoring range is 5 meters, and adaptable monitoring angle is wide, the scene that the monitoring distance is close needs. In this example, the monitoring angle can be adjusted to the camera to the showcase height of correspondence difference. For example, when the height of the showcase is 2.2 meters, the camera monitoring angle is 80 degrees, so the camera horizontally rotates 50 degrees downwards, and thus the camera can shoot images in front of the showcase without dead angles, and the range covers people with the height within 3.6 meters away from the showcase and less than 1.8 meters away from the showcase. In addition, the specific position of the camera is not limited to be arranged on the top of the showcase, as long as the view range covers the peripheral area of the showcase. As the camera for anti-theft monitoring is arranged in places such as museums, an application scene can be expanded, namely, the existing camera is utilized to collect images and the images are directly transmitted to the MCU of the showcase for behavior detection.
In some embodiments, the controller 12 for performing behavior detection on the display device peripheral image comprises:
extracting the personnel arm behavior characteristic information and the photographing equipment characteristic information in the peripheral image of the display device;
and inputting the characteristic information of the arm behaviors of the personnel and the characteristic information of the photographing equipment into a pre-trained recognition model so as to recognize whether the photographing behaviors exist or not through the pre-trained recognition model.
Therefore, the shooting behavior can be accurately and efficiently detected by utilizing the recognition model, such as the deep learning network model, for recognizing the arm behavior characteristics with strong robustness and strong representation for the shooting behavior and the characteristics of the shooting equipment such as a camera, a mobile phone and the like.
In a specific example, after detecting that a guest picks up a key feature of a photographing device such as a camera, a smart phone, and the like to photograph an exhibit, the controller cuts out an arm and the photographing device as main feature regions, inputs the main feature regions into a pre-trained recognition model to perform action feature comparison, and completes behavior classification to recognize whether a photographing action exists. Wherein, the key features when the tourist takes a picture are shown as 7-a to 7-e in fig. 7, 7-a shows the main feature area when the camera is held by the right hand, 7-b shows the main feature area when the camera is held by the left hand, 7-c shows the main feature area when the camera is held by the two hands, 7-d shows the main feature area when the arm is at a horizontal angle with the camera, and 7-e shows the main feature area when the arm is at a vertical angle with the camera.
