Detailed ways

As mentioned above, after the audience shoots or records the performance content, they may inadvertently share the filmed or recorded performance content on social networks, and the unintentional behavior of the audience will cause the leakage of the performance content, which in turn will lead to the infringement of the copyright of the performance content.

Although when the audience enters the venue, the performance venue will inform the audience not to shoot or record the content of the performance during the performance through radio and other forms, but the reminder is weak.

In the embodiment of the present invention, according to the image information of each viewer, the candidate viewers of the handheld camera equipment are determined, and then the target viewers with the possibility of unauthorized recording are determined. After the target audience is determined, by controlling the reminder device to output a reminder signal to the target audience, the target audience can be reminded to stop unauthorized recording, thereby avoiding leakage of performance content.

In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

An embodiment of the present invention provides a copyright protection method for performance venues. Referring to FIG. 1 , specific steps will be described in detail below.

Step S101, acquiring images of audience seats in a performance venue in real time.

In a specific implementation, a plurality of cameras can be set in the performance place in advance, and images in the performance place can be collected in real time through the plurality of cameras. Multiple cameras can be set in different positions of the performance venue, and each camera can collect images of a part of the performance venue. The images collected by multiple cameras can completely cover the entire performance venue, and there is no blind area for image collection.

The camera can be an infrared camera, a fisheye camera or other types of cameras. Under normal circumstances, the light in the performance venue is relatively dark, and when an ordinary camera is used to collect images, the collected images may be blurred. Therefore, in order to obtain a clearer image in the performance venue, an infrared camera can be used to capture a clearer image. The principle of image acquisition by the infrared camera can refer to the prior art, and the embodiment of the present invention will not repeat it. The performance venue can be a movie theater, an opera house or other venues.

After the real-time images in the performance venue are collected, the real-time images of each audience seat in the performance venue can be obtained.

Step S102, identify and analyze the image, and acquire video information of each viewer.

In a specific implementation, after the image of each audience seat in the performance venue is acquired, the position of each audience can be determined, and then the image information of each audience can be obtained.

Specifically, after acquiring the image of each audience seat in the performance venue, it can be determined which audience seats have audiences. After the audience seats where audiences exist are determined, the image information of each audience can be acquired.

Step S103, according to the image information of each viewer, determine a candidate viewer holding a camera device, and obtain an angle at which the candidate viewer holds the camera device.

In a specific implementation, after the image information of each viewer is acquired, the image information of each viewer may be analyzed to determine which viewers are currently holding a photographic device.

After acquiring the image information of each viewer, it can be detected whether each viewer is holding a photographic device. In practical applications, the photography device is usually a smart terminal with a built-in camera, such as a smart phone or a camera. When analyzing the image information of each spectator, it can be detected whether there is an image of the photographic equipment in the image information of the spectator. When it is detected that the image information of a viewer includes the image of the photographic equipment, the viewer can be determined as a candidate viewer. After the viewer is determined to be a candidate viewer, the angle at which the viewer holds the photographing device may be further acquired.

Step S104, when it is detected that the angle at which the candidate viewer is holding the photography device is within a preset angle range, determine that the candidate viewer is a target viewer who may have unauthorized recording.

In a specific implementation, the preset angle range may be an angle range within which the performance content can be photographed by the candidate audience's handheld camera device. That is to say, when the angle at which the candidate audience holds the camera device is within the preset angle range, the camera device can capture the content of the performance.

In the embodiment of the present invention, the angle at which the audience holds the photographic device may be: when the audience holds the photographic device, the angle of the lens of the photographic device relative to the horizontal plane at the viewer's perspective.

In practical applications, pre-tests can be used to know the maximum and minimum angles at which the photography equipment can record the content of the performance when the audience sits on the audience seats and holds the photography equipment. The preset angle range can be determined according to the pre-obtained maximum angle and minimum angle.

For example, in practical applications, through pre-testing, it is known that when the audience is sitting in the audience seats, the maximum angle at which the handheld camera equipment can record the performance content is 110°, and the minimum angle is 70°, so the set angle range is 70° ~110°.

It can be known from practical application that most of the performance venues are stepped. Therefore, audiences at different positions watch the content of the performance from different angles. Correspondingly, if the audience wants to record the performance content without authorization, the angles of the handheld camera equipment may also be different when the audience in different positions records the performance content.

When the audience is in the front row of the performance venue, the height of the seats in the front row is low, so the angle required for the audience to hold the camera equipment to capture the performance content is relatively large; conversely, when the audience is in the back row of the performance venue, the seats in the back row The height is high, so the angle required for the audience to hold the camera equipment to capture the performance content is relatively small.

If the same preset angle range is set for all the seats in the performance venue, misjudgment may occur.

For example, for all the seats in the performance venue, the corresponding preset angle ranges are 70°-110°. For the audience in the front row, when the angle of the camera is held at 70°, they may just open the smart phone to check the information, not for unauthorized recording.

Therefore, in the embodiment of the present invention, in order to avoid the above misjudgment, a one-to-one corresponding angle range can be set for each row of positions in the performance venue; it can also be set for several rows of positions in the performance venue. Corresponding angle range.

For example, for the first row of positions in the performance venue, the corresponding angle range is set to be 70°-90°; for the second row of positions in the performance venue, the corresponding angle range is set to be 75°-95°.

As another example, for the first three rows in the performance venue, set the corresponding angle range from 70° to 95°; for the fourth to sixth rows in the performance venue, set the corresponding angle range from 80° to 100° °.

Therefore, the preset angle range corresponding to the specific position may be determined according to the current specific position of the candidate viewer. Afterwards, it is judged whether the angle at which the candidate viewer holds the camera device is within the preset angle range.

Continue to use the above example for illustration. It is detected that the candidate audience is currently in the third row of the performance venue, and the preset angle range corresponding to the third row of the performance venue is 70°-95°, and the angle of the candidate audience’s hand-held camera equipment is 85°, so the candidate audience is determined The audience is the target audience where there is a possibility of unauthorized recording.

In a specific implementation, after the image information of the audience is acquired, the current specific location of the audience can be determined. In the embodiment of the present invention, information such as the seat row number and seat number where the audience is located can be obtained from the obtained audience image information, so as to determine the specific location of the audience.

In a specific implementation, when it is detected that the angle at which the candidate viewer is holding the camera device is within a preset range, the candidate viewer may not have a subjective willingness to perform unauthorized recording. For example, candidate viewers just pull out their smartphones to reply to messages or check the time. If the candidate viewer subjectively has the willingness to perform unauthorized recording, the candidate viewer will hold the camera device for a period of time, and the angle of the camera device during the time period is within the preset angle range.

Therefore, in the embodiment of the present invention, in order to determine the target audience more accurately, when it is detected that the angle of the candidate audience holding the camera device is within the preset angle range, it is not immediately determined that the candidate audience is the target audience, but further It is judged whether the time period for which the candidate viewer holds the camera device within the preset angle range reaches the preset first time period. When it is detected that the angle of the candidate viewer's hand-holding camera device is within the preset angle range for a duration reaching the preset first duration, it is determined that the candidate viewer is a target audience with the possibility of unauthorized recording.

The first duration may be set according to an actual application scenario. Usually, the duration of the video used for commercial dissemination or pirated recording will be longer than 10s. Therefore, the first duration may be set as 10s. It can be understood that the first duration may also be set to other values, which will not be described one by one in this embodiment of the present invention.

Step S105, controlling the reminder device to output a reminder signal to remind the target audience to stop unauthorized recording.

In a specific implementation, after the target audience is determined, a reminder device may be used to remind the target audience to stop unauthorized recording.

In a specific application, a one-to-one corresponding reminding device can be arranged on each seat, and the reminding device can be arranged on the handle of the seat, or on the backrest of the seat. After the target audience is determined, the current specific location of the target audience can be known, that is, the specific seat number of the target audience. A reminder signal is output to the corresponding reminder device of the target audience. After receiving the reminder signal, the reminder device can work in the form of vibration, thereby reminding the target audience to stop unauthorized recording.

Through the reminding device corresponding to the seat one by one, while reminding the target audience on the seat, other audiences in the performance venue will not be greatly affected, and the reminding effect is better.

In a specific implementation, illuminating lights can also be set in the performance hall. After the target audience is determined, the illuminating lamp can be controlled to output light to illuminate the target audience, thereby reminding the target audience to stop unauthorized recording.

It can be understood that the reminder device may also include other types of devices, and is not limited to the examples in the above embodiments of the present invention, as long as it can remind the target audience.

In practical applications, there may also be situations where the target audience ignores the reminder and continues to go its own way after reminding the target audience.

In order to effectively protect the copyright of the performance content, in the embodiment of the present invention, after the target audience is reminded by the reminder device, if the target audience still holds the camera device and the angle of the camera device is still within the preset angle range, then The reminder device can be controlled to output a warning signal to warn the target audience to stop unauthorized recording.

In practical applications, there may also be cases where the target audience puts away the photography equipment after the target audience is reminded for the first time. However, after a while, the target audience reverted to picking up camera equipment for unauthorized recording.

In the embodiment of the present invention, after the target audience is reminded by the reminding device, if it is detected that the target audience is holding the photographic device again within the second time period, and the angle of the handheld photographic device is still within the preset angle range, then the The warning device is controlled to output a warning signal to warn the target audience of unauthorized recording.

In a specific implementation, compared with the reminder signal output by the reminder device, the warning signal output by the reminder device can be stronger, and can attract the attention of the target audience to a greater extent. For example, the reminder signal output by the reminder device is a vibration signal, and the vibration level of the vibration signal corresponding to the warning signal may be stronger than the vibration level corresponding to the vibration signal.

In another example, if the reminder signal output by the reminder device is the light output by the illuminating lamp, the light intensity corresponding to the warning signal may be higher than the light intensity corresponding to the reminder signal.

If the warning signals still cannot prevent the target audience from making unauthorized recordings, the intervention of on-site staff can be used to improve the copyright protection of performance content.

In the embodiment of the present invention, after the reminder device is controlled to output the reminder signal, prompt information can also be output to the pre-associated smart terminal. Cumulative number of authorized recordings. After receiving the prompt information, the smart terminal can display the current location information of the target audience and the cumulative number of unauthorized recordings during the performance on the display screen. On-site staff can obtain the current location information of the target audience and the cumulative number of unauthorized recordings during the performance according to the display on the smart terminal.

If the number of unauthorized recordings during this performance is 1, it means that the target audience is making unauthorized recordings for the first time, and the on-site staff does not need to enter the performance venue for manual intervention.

If the target audience still conducts unauthorized recording, after controlling the reminding device to output warning information, it can also continue to output prompt information to the pre-associated smart terminal. In the prompt information, the cumulative number of unauthorized recordings made by the target audience during this performance is updated to 2.

The on-site staff obtained the current location information of the target audience according to the display on the smart terminal, and learned that the cumulative number of unauthorized recordings during this performance was 2. At this time, on-site staff can enter the performance venue for manual intervention. For example, a field worker can walk up to a target audience and make a voice call.

It is understandable that the on-site staff can determine the time and method of manual intervention according to the specific application scenario and the corresponding regulations of the performance venue.

In a specific implementation, when determining the candidate viewers holding the camera device according to the image information of each viewer, which viewers are currently holding the object can be determined from the image information of each viewer. For a spectator holding an item, it can be further judged whether the item held by the spectator is a photographic device or other items according to the characteristics of the item held by the spectator.

In the embodiment of the present invention, when determining whether the object held by the audience is a photographic device, it may be detected whether the object has reflection phenomenon. When the item has reflection phenomenon, and the shape of the item is square, it can be determined that the item is a photographic device.

When presenting performances in a performance venue, the lighting on the stage or screen is usually stronger than the lighting in the audience seats. When the audience holds smartphones and other photographic equipment facing the stage or screen, the camera of the photographic equipment will produce reflections. In addition, existing photographic equipment such as smartphones and cameras usually have a square appearance. Therefore, it can be determined whether the object held by the audience is a photographic equipment based on whether the object held by the audience has reflections and the shape of the object.

It can be known in a specific implementation that the posture of the audience holding the camera device may include holding it with one hand and holding it with both hands. Usually, in order to maintain the stability of shooting images and recording videos, the audience holds the two ends of the camera device with both hands to shoot images or record videos.

In the embodiment of the present invention, when it is detected that the audience is holding an object, it may also be determined according to the distance between the hands whether the object being held is a photographic device. Portable photography equipment is usually a smart phone, and the length of the smart phone is usually between 10 cm and 20 cm. Therefore, a target distance of 10 cm can be preset.

When it is detected that the audience is holding an object with both hands, and the distance between the hands is greater than 10 cm, it can be determined that the object held is a photographic device.

It can be understood that the set target distance may also be other distance values, which may be set according to specific application scenarios.

When the audience holds an item with one hand, the size of the item held by the audience can be obtained. If the size of the object held by the audience matches the size of the preset smart phone, it can be determined that the object held by the audience is a photographic device.

In a specific implementation, when determining the candidate viewers of the handheld camera device according to the image information of each viewer, the posture information of each viewer may be obtained according to the image information of each viewer. According to the posture information of each audience within the preset time length, the behavior information of each audience can be determined. According to the behavior information of each audience, the candidate audience for handheld camera equipment is determined.

In the embodiment of the present invention, after acquiring the posture information of each audience within the preset time length, the behavior information of the audience within the preset time length can be determined according to the change of the audience's posture information within the preset time length . The preset time length can be set according to specific application scenarios and application requirements. For example, the preset time length is 10s. In another example, the preset time length is 20s.

When it is detected within the preset time length that the audience raises both hands and the audience is holding the photographic equipment, it can be determined that the audience's behavior information is to pick up the photographic equipment, so it can be determined that the audience is a candidate audience.

When within the preset time length, it is detected that the audience raises one hand, and the raised hand holds the camera equipment, it can be determined that the audience’s behavior information is to pick up the camera equipment, so it can be determined that the audience is a candidate audience .

In a specific implementation, the audience may place and fix the photographic equipment next to the seat, and perform unauthorized recording by adjusting the placement angle of the photographic equipment. For example, in a movie theater, armrests are usually arranged next to audience seats, and the armrests include a main body and cup holders for placing beverages. Spectators place camera equipment in cup holders next to their seats.

With regard to the above scenario, in the embodiment of the present invention, if it is detected that the cup holder corresponding to a certain seat has a reflective phenomenon, it may also be determined that the audience corresponding to the seat is a candidate audience. After the candidate audiences are determined, the vertical angle of the photography equipment relative to the ground can be obtained. When the vertical angle of the photography device relative to the ground is within a preset angle range, the candidate audience can be determined as the target audience. After the candidate viewer is determined to be the target viewer, step S105 and subsequent operations provided in the above-mentioned embodiments of the present invention may be performed, and details are not described here.

In a specific implementation, after controlling the reminding device to output the reminding signal, the control signal can also be output to the preset infrared light emitting device; or, after controlling the reminding device to output the warning signal, output the control signal to the preset infrared light emitting device .

After receiving the control signal, the infrared light emitting device can generate and emit infrared light. The infrared light emitting device can emit the generated infrared light to the stage or screen of the performance place. Since infrared light is invisible to human eyes, and infrared light is visible to cameras, video images captured by photographic equipment will be interfered by infrared light.

The infrared light emitting device can also emit the generated infrared light to the position where the target audience is located, so as to interfere with the photographic equipment held by the target audience.

By controlling the infrared light emitting device to emit infrared light, it is possible to interfere with the photographic equipment for unauthorized recording of the performance content, thereby further protecting the copyright of the performance content.
