Detailed Description
As described above, after capturing or recording the performance content, the audience may unintentionally share the captured or recorded performance content to the social network, and the unintentional actions of the audience may cause leakage of the performance content, which may further cause the copyright of the performance content to be infringed.
Although the audience can inform the audience of the fact that the audience does not shoot or record the performance content in the performance process through broadcasting and the like when the audience enters the venue, the reminding strength is poor.
In the embodiment of the invention, candidate audiences of the handheld photographic equipment are determined according to the image information of each audience, and then target audiences with possible unauthorized recording are determined. After the target audience is determined, the reminding device is controlled to output a reminding signal to the target audience, so that the target audience can be reminded to stop unauthorized recording, and leakage of the performance content can be avoided.
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a method for protecting copyrights of a performance place, which is described in detail through specific steps with reference to fig. 1.
Step S101, acquiring images of seats of audience in the performance site in real time.
In a specific implementation, a plurality of cameras may be provided in the performance site in advance, and images in the performance site may be acquired in real time by the plurality of cameras. The multiple cameras can be arranged at different positions of the performance place respectively, each camera can collect images of partial areas in the performance place, the images collected by the multiple cameras can completely cover the inside of the whole performance place, and no dead zone for image collection exists.
The camera can be an infrared camera, a fish-eye camera or other types of cameras. Typically, the light in the performance is darker, and when an ordinary camera is used to capture images, the captured images may be blurred. Therefore, in order to obtain a clearer image in the performance place, an infrared camera can be used to capture the clearer image. The principle of image acquisition by the infrared camera can refer to the prior art, and the embodiment of the invention is not repeated. The performance venue may be a movie theater, an opera house, or other venue.
After the real-time images of the venue are acquired, the real-time images of each audience seat in the venue can be obtained.
Step S102, the image is identified and analyzed, and image information of each audience is obtained.
In an implementation, after the image of each audience seat in the performance venue is acquired, the position of each audience can be determined, so that the image information of each audience can be acquired.
Specifically, after an image of each audience seat within the performance venue is acquired, it can be determined which audience seats have an audience thereon. After determining that the audience seats of the audience exist, image information of each audience can be acquired.
Step S103, determining candidate audiences of the handheld photographing device according to the image information of each audience, and acquiring angles of the candidate audiences for holding the photographing device.
In implementations, after the image information for each viewer is obtained, the image information for each viewer may be analyzed to determine which viewers are currently holding the photography device.
After the image information of each viewer is acquired, it is possible to detect whether each viewer holds the photographing apparatus. In practical applications, the photographing apparatus is typically a smart terminal with a built-in camera, such as a smart phone or a camera. In analyzing the image information of each viewer, it is possible to detect whether or not there is an image of the photographing apparatus in the image information of the viewer. When the image information of a certain audience is detected to comprise the image of the photographing device, the audience can be determined to be a candidate audience. After determining that the audience is a candidate audience, the angle at which the audience holds the photographing apparatus may be further acquired.
Step S104, when the angle of the candidate audience holding the photographic equipment is detected to be within the preset angle range, the candidate audience is determined to be a target audience with unauthorized recording possibility.
In a specific implementation, the preset angle range may be an angle range in which the candidate audience can capture the performance content by using the handheld photographing device. That is, when the angle at which the candidate audience holds the photographing apparatus is within the preset angle range, the photographing apparatus can photograph the performance content.
In the embodiment of the present invention, the angle of the handheld photographing device of the audience may be: when a viewer holds the photographing apparatus, the angle of the lens of the photographing apparatus with respect to the horizontal plane at the viewing angle of the viewer.
In practical applications, the maximum angle and the minimum angle of the performance content recorded by the photographing device can be known through a pre-test when the photographing device is held by a spectator sitting on a spectator seat. The preset angle range may be determined according to a maximum angle and a minimum angle obtained in advance.
For example, in practical application, through a pre-test, it is known that when a spectator sits on a spectator seat, the handheld photographing device can record the content of the performance at a maximum angle of 110 ° and a minimum angle of 70 °, and the set angle range is 70 ° to 110 °.
In practice, most of the performance sites are stepped, so that the viewing angles of the audience at different positions are different. Accordingly, if the audience wants to record the performance content without authorization, the angle of the handheld photographing device may be different when the audience at different positions records the performance content.
When the audience is in the front row of the performance place, the seat height of the front row is lower, so that the angle required by the audience to shoot the performance content by holding the photographic equipment is larger; conversely, when the audience is at the back row of the performance, the seat height of the back row is higher, so the angle required for the audience to shoot the performance content by holding the photographing device is smaller.
If the same preset angle range is set for all seats in the performance venue, misjudgment may occur.
For example, for all seats in a performance venue, the corresponding preset angle range is 70 ° to 110 °. For the front-end audience, when the angle of the handheld photographic device is 70 degrees, the smart phone may be turned on to view information, and the information is not recorded in an unauthorized mode.
Therefore, in the embodiment of the present invention, in order to avoid the occurrence of the above-mentioned misjudgment, a one-to-one corresponding angle range may be set for each row of positions in the performance location; the corresponding angular ranges may also be set for several rows of positions within the performance venue.
For example, for the first row of positions in the performance site, the corresponding angle range is set to 70 ° to 90 °; for the second row of positions in the performance site, the corresponding angle range is set to 75-95 degrees.
For another example, for the first three rows of positions in the performance place, setting the corresponding angle range to be 70-95 degrees; the corresponding angle range is set to 80-100 degrees for the 4 th to 6 th rows in the performance place.
Therefore, according to the specific position of the candidate audience, the preset angle range corresponding to the specific position can be determined. Then, judging whether the angle of the handheld photographic equipment of the candidate audience is within a preset angle range or not.
The above illustration continues. And when the candidate audience is detected to be currently in the third row of the performance place, acquiring a preset angle range corresponding to the third row of the performance place to be 70-95 degrees, wherein the angle of the handheld photographing equipment of the candidate audience is 85 degrees, so that the candidate audience is determined to be a target audience with the possibility of unauthorized recording.
In an implementation, after the image information of the audience is acquired, the specific position where the audience is currently located can be determined. In the embodiment of the invention, the information such as the number of the seat rows and the seat numbers of the audience can be acquired from the acquired audience image information, so that the specific position of the audience can be determined.
In an implementation, when the angle of the handheld photographing device of the candidate audience is detected to be within the preset range, the candidate audience may not have a subjective intention of performing unauthorized recording. For example, the candidate audience simply takes the smartphone reply message or looks at the time. If the candidate audience subjectively has the intention of unauthorized recording, the candidate audience can hold the photographing device for a period of time, and the angle of the photographing device is within a preset angle range during the period of time.
Therefore, in the embodiment of the present invention, in order to more accurately determine the target audience, when the angle of the handheld photographing device of the candidate audience is detected to be within the preset angle range, it is not immediately determined that the candidate audience is the target audience, but it is further determined whether the duration of the handheld photographing device of the candidate audience within the preset angle range reaches the preset first duration. And when detecting that the duration that the angle of the handheld photographic equipment of the candidate audience is within the preset angle range reaches the preset first duration, determining the candidate audience as a target audience with the possibility of unauthorized recording.
The first duration may be set according to an actual application scenario. Typically, video duration for commercial distribution or piracy will be greater than 10 seconds. Thus, the first time period may be set to 10s. It can be understood that the first time length may also be set to other values, which are not described in detail in the embodiments of the present invention.
Step S105, the reminding device is controlled to output a reminding signal so as to remind the target audience to stop unauthorized recording.
In an implementation, after the target audience is determined, the target audience may be alerted by a reminder to stop unauthorized recording.
In a specific application, for each seat, a reminding device corresponding to each seat one by one is arranged on the seat, and the reminding device can be arranged on a handle of the seat or on a backrest of the seat. After the target audience is determined, the current specific location of the target audience, i.e., the specific seat number of the target audience, can be known. And outputting a reminding signal to a target audience as a corresponding reminding device. The reminding device can work in a vibrating mode after receiving the reminding signal, so that a target audience is reminded to stop unauthorized recording.
Through the reminding device corresponding to the seats one by one, the target audience on the seats is reminded, and meanwhile, the reminding device can not cause larger influence on other audiences in the performance place, and the reminding effect is good.
In implementations, the illumination light may also be provided in a performance venue. After the target audience is determined, the irradiation lamp can be controlled to output light to irradiate the target audience, so that the target audience is reminded to stop unauthorized recording.
It will be appreciated that the alert device may also comprise other types of devices, not limited to the examples of the above embodiments of the present invention, as long as the targeted audience can be alerted.
In practical applications, there may be situations where the target audience is alerted, ignoring the alert, and still my essence.
In order to effectively protect copyrights of performance contents, in the embodiment of the present invention, after reminding a target audience by the reminding device, if the target audience still holds the photographing device and the angle of the handheld photographing device is still within the preset angle range, the reminding device may be controlled to output a warning signal to warn the target audience to stop unauthorized recording.
In practical applications, there may be a possibility that the target audience has stowed the photographing apparatus after the target audience has been alerted for the first time. However, after a period of time, the target viewer again picks up the photographing apparatus for unauthorized recording.
In the embodiment of the invention, after reminding the target audience by the reminding device, if the target audience is detected to hold the photographic equipment again in the second time period and the angle of the handheld photographic equipment is still within the preset angle range, the reminding device can be controlled to output a warning signal so as to warn the target audience to remind to record in an unauthorized mode.
In a specific implementation, compared with the reminding signal output by the reminding device, the warning signal output by the reminding device can be stronger, and the attention of a target audience can be brought to a greater extent. For example, the reminding signal output by the reminding device is a vibration signal, and the vibration level of the vibration signal corresponding to the warning signal can be stronger than that of the vibration signal corresponding to the vibration signal.
For another example, the reminding signal output by the reminding device is the light output by the illumination lamp, and the light intensity corresponding to the reminding signal can be higher than the light intensity corresponding to the reminding signal.
If the warning signal still cannot prevent the target audience from carrying out unauthorized recording, the copyright protection strength of the performance content can be improved through the intervention of on-site staff.
In the embodiment of the invention, after the reminding device is controlled to output the reminding signal, the reminding device can also output the reminding information to the pre-associated intelligent terminal, wherein the reminding information can comprise the current position information of the target audience and the accumulated times of unauthorized recording of the target audience in the performance process. After receiving the prompt information, the intelligent terminal can display the current position information of the target audience and the accumulated times of unauthorized recording in the current performance process on a display screen. The on-site staff can acquire the current position information of the target audience and the accumulated times of unauthorized recording in the performance process according to the display on the intelligent terminal.
If the number of times of unauthorized recording in the present performance is 1, it indicates that the target audience is the first time of unauthorized recording, and then the on-site staff can do not need to enter the performance place to perform manual intervention.
If the target audience still carries out unauthorized recording, after the reminding device is controlled to output the warning information, the reminding information can be further output to the pre-associated intelligent terminal. In the prompt information, the accumulated times of unauthorized recording by the target audience in the current performance process is updated to 2.
And the on-site staff acquires the current position information of the target audience according to the display on the intelligent terminal, and acquires that the cumulative number of times of unauthorized recording in the current performance process is 2. At this time, the field staff can enter the performance site to perform manual intervention. For example, a live worker may walk into the vicinity of a target audience for voice prompts.
It will be appreciated that the time and manner in which the manual intervention is performed may be determined by the field staff based on the particular application scenario and the corresponding specifications of the performance venue.
In implementations, in determining candidate viewers for the handheld photography device based on the image information for each viewer, it is possible to determine which viewers are currently holding the item from the image information for each viewer. For the audience holding the articles, the audience can further judge whether the articles held by the audience are photographic equipment or other articles according to the characteristics of the articles held by the audience.
In the embodiment of the invention, when determining whether the object held by the audience is the photographic equipment, whether the object has the reflection phenomenon or not can be detected. When there is a reflection phenomenon of the article, and the shape of the article is square, it can be determined that the article is a photographing apparatus.
When showing content in a performance venue, the lights of the stage or screen are typically stronger than the lights of the spectator seat. When a viewer holds a camera such as a smart phone to face a stage or a screen, reflection of light occurs at a camera of the camera. In addition, the existing photographing apparatuses such as smartphones and cameras are generally square in appearance, and thus, whether an object held by a viewer is a photographing apparatus can be determined by whether there is reflection of light on the object held by the viewer and the appearance of the object.
In particular implementations, the gestures of a viewer holding a photographic device may include one-handed as well as two-handed. In general, in order to maintain stability of capturing images and recording video, viewers hold the photographing apparatus with both hands to capture images or record video.
In the embodiment of the invention, when the object held by the audience is detected, whether the held object is the photographic equipment can be judged according to the distance between the two hands. The portable camera device is typically a smart phone, which is typically between 10 cm and 20 cm long. Therefore, the target distance may be set to 10 cm in advance.
When the object is held by the hands of the audience and the distance between the hands is more than 10 cm, the object to be held can be judged to be photographic equipment.
It can be appreciated that the set target distance may be other distance values, and may be set according to a specific application scenario.
The size of the article held by the viewer can be obtained when the viewer holds the article with one hand. If the size of the object held by the audience is matched with the preset size of the smart phone, the object held by the audience can be determined to be photographic equipment.
In a specific implementation, when determining candidate viewers of the handheld photographing device according to the image information of each viewer, pose information of each viewer may be obtained according to the image information of each viewer. According to the gesture information of each audience in the preset time length, the behavior information of each audience can be determined. And further determining candidate audiences of the handheld photographic equipment according to the behavior information of each audience.
In the embodiment of the invention, after the gesture information of each audience in the preset time length is obtained, the behavior information of the audience in the preset time length can be determined according to the change of the gesture information of the audience in the preset time length. The preset time length can be set according to specific application scenes and application requirements. For example, the preset time period is 10s. For another example, the preset time period is 20s.
When the lifting of both hands of the audience is detected within the preset time period and the photographing device is held in the hands of the audience, the behavior information of the audience can be determined to be that the photographing device is picked up, so that the audience can be determined to be a candidate audience.
When the lifting of the audience is detected by one hand within the preset time length and the photographing device is held in the lifted hand, the behavior information of the audience can be determined to be that the photographing device is lifted, so that the audience can be determined to be a candidate audience.
In practice, the viewer may place the photographing apparatus beside the seat and fix it, and perform unauthorized recording by adjusting the placement angle of the photographing apparatus. For example, in movie theatres, armrests are often provided alongside audience seats, which comprise a main body portion and a cup holder for holding a beverage. The spectator places the photographic device in the seat side cup holder.
In view of the above-described situation, in the embodiment of the present invention, if it is detected that the cup holder corresponding to a certain seat has a reflection phenomenon, it may also be determined that the audience corresponding to the seat is a candidate audience. After the candidate audience is determined, the vertical angle of the photographing apparatus with respect to the ground may be acquired. When the vertical angle of the photographing apparatus with respect to the ground is within a preset angle range, the candidate audience can be determined as the target audience. After determining that the candidate audience is the target audience, step S105 and subsequent operations provided in the above embodiments of the present invention may be performed, which will not be described herein.
In a specific implementation, after the reminding device is controlled to output the reminding signal, a control signal can be output to a preset infrared light emitting device; or after the reminding device is controlled to output the warning signal, outputting a control signal to a preset infrared light emitting device.
The infrared light emitting device may generate infrared light and emit the same after receiving the control signal. The infrared light emitting device may emit the generated infrared light toward a stage or screen of the performance venue. Since infrared light is invisible to the human eye and infrared light is visible to the camera, video images captured by the photographing apparatus may be disturbed by infrared light.
The infrared light emitting device may also emit generated infrared light toward a location where the target audience is located to interfere with a photographing apparatus held by the target audience.
By controlling the infrared light emitting device to emit infrared light, the photographic equipment for unauthorized recording of the performance content can be disturbed, so that copyrights of the performance content can be further protected.
