Detailed Description
As described above, after capturing or recording the performance content, the viewers may unintentionally share the captured or recorded performance content with the social network, and the unintentional actions of the viewers may cause the leakage of the performance content, thereby infringing the copyright of the performance content.
Although the audience can be informed of the content of the performance by broadcasting or the like when the audience enters the performance, the reminding strength is poor.
In the embodiment of the invention, the candidate audiences of the handheld photographic equipment are determined according to the image information of each audience, and further the target audiences with the possibility of 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 the leakage of the performance content can be avoided.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
The embodiment of the invention provides a copyright protection method for a performance place, and the copyright protection method is described in detail through specific steps with reference to fig. 1.
Step S101, images of seats of audiences in the performance places are obtained in real time.
In specific implementation, a plurality of cameras can be arranged in the performance place in advance, and images in the performance place can be collected in real time through the plurality of cameras. The plurality of cameras can be respectively arranged at different positions of the performance place, each camera can collect images in different areas inside the performance place, the images collected by the plurality of cameras can completely cover the inside of the whole performance place, and no image collection blind area exists.
The camera can be an infrared camera, and also can be a fisheye camera or other types of cameras. In general, light in a performance place is dark, and when an ordinary camera is used for collecting images, the collected images may be blurred. Therefore, in order to acquire clear images in the performance place, clear images can be shot by using the infrared camera. The principle of acquiring images by the infrared camera can refer to the prior art, and the embodiment of the invention is not described in detail. The performance place can be a movie theater, or an opera house or other places.
After the real-time image in the performance site is acquired, the real-time image of each audience seat in the performance site can be obtained.
And step S102, identifying and analyzing the image, and acquiring the image information of each audience.
In a specific implementation, after the image of each audience seat in the performance place is obtained, the position of each audience can be determined, and then the image information of each audience is obtained.
In particular, after an image of each audience seat within the performance venue is acquired, it can be determined which audience seats have an audience on them. After the presence of the audience seats of the audience is determined, the image information of each audience can be obtained.
Step S103, determining candidate audiences of the handheld photographic equipment according to the image information of each audience, and acquiring the angles of the candidate audiences holding the photographic equipment.
In a specific implementation, after the image information of each viewer is obtained, the image information of each viewer may be analyzed to determine which viewers currently hold the camera device.
After the image information of each audience is acquired, whether each audience holds the photographic equipment or not can be detected. In practical applications, the photographing device is usually a smart terminal with a built-in camera, such as a smart phone or a camera. When the image information of each audience is analyzed, whether the image of the photographing equipment exists in the image information of the audience can be detected. When the image information of a certain viewer is detected to include the image of the photographing device, the viewer can be determined as a candidate viewer. After determining that the viewer is a candidate viewer, the angle at which the viewer holds the camera device may be further obtained.
And step S104, when the condition that the angle of the candidate audience holding the photographic equipment is within the preset angle range is detected, determining that the candidate audience is a target audience with possible unauthorized recording.
In a specific implementation, the preset angle range may be an angle range within which the candidate audience handheld photographing device can shoot the content of the performance. That is, when the angle at which the candidate viewer holds the photographing apparatus is within the preset angle range, the photographing apparatus can photograph the show content.
In the embodiment of the present invention, the angle at which the viewer holds the photographing apparatus may be: the angle of the lens of the photographic device relative to the horizontal plane at the viewer's viewing angle when the viewer holds the photographic device.
In practical applications, it can be known through a previous test that the camera device can record the maximum angle and the minimum angle of the content of the performance when the audience sits on the audience seat and holds the camera device. The preset angle range may be determined according to the maximum angle and the minimum angle obtained in advance.
For example, in practical applications, through a previous test, when it is known that the handheld camera device can record the performance content at a maximum angle of 110 ° and a minimum angle of 70 °, the set angle range is 70 ° to 110 °.
In practice, most of the performance sites are stepped, so that viewers at different positions watch the content of the performance at different angles. Accordingly, if the viewer wants to record the performance content without authorization, the angle of the handheld camera device may be different when the viewer at different locations 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 for the audience to shoot the performance content by the camera equipment is larger; on the contrary, when the audience is in the back row of the performance place, the height of the seat in the back row is higher, so that the angle required for the audience to shoot the performance content by holding the camera device is smaller.
If the same preset angle range is set for all seats in the performance site, a situation of misjudgment may occur.
For example, the corresponding preset angle ranges are all 70-110 degrees for all seats in the show venue. For the front audience, when the angle of the handheld photographic device is 70 °, the smart phone may be turned on to view the information, but 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 may be set for each row of positions in the performance site; corresponding angle ranges can also be set for several rows of positions in the performance site.
For example, for a first row position in a performance site, a corresponding angle range is set to be 70-90 degrees; for the second row position within the performance site, the corresponding angle range is set to 75-95 °.
For another example, for the first three rows of positions in the performance site, the corresponding angle range is set to be 70-95 degrees; the corresponding angle range is set to 80 to 100 degrees for the 4 th row to the 6 th row in the presentation space.
Therefore, the preset angle range corresponding to the specific position can be determined according to the specific position where the candidate audience is currently located. And then, judging whether the angle of the candidate audience hand-held photographic equipment is within a preset angle range.
The description continues with the above example. And detecting that the candidate audience is currently positioned in the third row of the performance place, acquiring that the preset angle range corresponding to the third row of the performance place is 70-95 degrees, and the angle of the candidate audience holding the photographic equipment is 85 degrees, so that the candidate audience is determined to be a target audience with the possibility of unauthorized recording.
In a specific implementation, after the image information of the viewer is obtained, the specific location where the viewer is currently located may be determined. In the embodiment of the invention, information such as the number of seat rows and the seat numbers of the audiences can be acquired from the acquired audience image information, so that the specific positions of the audiences can be determined.
In an implementation, when it is detected that the angle at which the candidate viewer holds the camera device is within the preset range, the candidate viewer may not have a subjective intention to perform unauthorized recording. For example, the candidate viewer simply takes a smartphone reply message or looks at the time. If the candidate audience has a subjective intention of recording without authorization, the candidate audience holds the photographic equipment within a period of time, and the angle of the handheld photographic equipment within the preset angle range within the period of time.
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 handheld photographing device of the candidate audience is within the preset angle range, the candidate audience is not immediately determined to be 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. When the fact that the duration that the angle of the candidate audience holding the photographic equipment is within the preset angle range reaches the preset first duration is detected, the candidate audience is determined to be the target audience with the possibility of unauthorized recording.
The first time period may be set according to an actual application scenario. Typically, the video time for commercial distribution or pirating will be greater than 10 s. Therefore, the first time period may be set to 10 s. It can be understood that the first time length may also be set to other values, and the description of the embodiments of the present invention is omitted.
And step S105, controlling a reminding device to output a reminding signal so as to remind the target audience to stop recording without authorization.
In an implementation, after the target audience is determined, the target audience can be reminded to stop unauthorized recording through a reminding device.
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 a handle of the seat or a backrest of the seat. After the target audience is determined, the current specific position of the target audience, namely the specific seat number of the target audience can be obtained. And outputting a reminding signal to a corresponding reminding device of the target audience. The reminding device can work in a vibration mode after receiving the reminding signal, so that the target audience is reminded to stop recording the program without authorization.
Through the reminding device corresponding to the seats one by one, when the target audience on the seats is reminded, other audiences in the performance place cannot be greatly influenced, and the reminding effect is good.
In particular implementations, lights may also be provided in the performance venue. After the target audience is determined, the illumination lamp can be controlled to output light to illuminate the target audience, so that the target audience is reminded to stop unauthorized recording.
It will be appreciated that the reminder device may also comprise other types of devices, and is not limited to the above embodiments of the invention, as long as the target audience can be reminded.
In practical applications, there may be a case where after the target viewer is reminded, the target viewer ignores the reminder and still goes to my element.
In order to effectively protect the copyright of the performance content, in the embodiment of the invention, after the target audience is reminded by the reminding device, if the target audience still holds the photographic equipment and the angle of the handheld photographic equipment is still within the preset angle range, the reminding device can be controlled to output the warning signal so as to warn the target audience to stop unauthorized recording.
In practical applications, there may be a case where the target viewer has retracted the photographing apparatus after the target viewer is reminded 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 the target audience is reminded by the reminding device, if the target audience is detected to re-hold the photographic equipment within the second time length and the angle of the handheld photographic equipment is still within the preset angle range, the reminding device can be controlled to output the warning signal so as to warn the target audience to remind the target audience to carry out unauthorized recording.
In specific implementation, the warning signal output by the reminding device can be stronger than the reminding signal output by the reminding device, and can attract the attention of the target audience 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 the vibration level corresponding to the vibration signal.
If the warning signal output by the warning device is the light output by the illuminating lamp, the light intensity corresponding to the warning signal can be higher than the light intensity corresponding to the warning signal.
If the warning signal still can not prevent the target audience from carrying out unauthorized recording, the copyright protection of the performance content can be enhanced through the intervention of field workers.
In the embodiment of the invention, after the reminding signal is output by the reminding device, the reminding information can be output to the pre-associated intelligent terminal, and 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 message, the intelligent terminal can display the current position information of the target audience and the accumulated times of unauthorized recording in the performance process on the display screen. The field staff can obtain 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 performance process is 1, the target audience is indicated to perform unauthorized recording for the first time, and field workers do not need to enter the performance site for 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 continuously output to the pre-associated intelligent terminal. In the prompt message, the cumulative number of times of unauthorized recording performed by the target audience in the performance process is updated to 2.
And the field worker acquires the current position information of the target audience according to the display on the intelligent terminal, and learns that the number of times of unauthorized recording in the performance process is 2. At this time, the field worker can enter the performance site for manual intervention. For example, a live worker may walk to the target audience for voice prompts.
It will be appreciated that the field personnel may determine when and how to perform manual intervention depending on the particular application scenario and the corresponding regulations of the performance venue.
In an implementation, when candidate viewers of the handheld photographic device are determined according to the image information of each viewer, which viewers currently hold the object can be determined from the image information of each viewer. For the audience holding the object, whether the object held by the audience is the photographic equipment or other objects can be further judged according to the characteristics of the object 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 a light reflection phenomenon can be detected. When the object has a light reflection phenomenon and the shape of the object is square, the object can be determined to be a photographing apparatus.
When showing the performance content in the performance venue, the lighting of the stage or screen is usually stronger than the lighting of the audience seats. When the audience holds the camera equipment such as a smart phone and the like to face a stage or a screen, the camera of the camera equipment reflects light. In addition, the existing photographing apparatuses such as smartphones and cameras are generally square in appearance, and therefore, whether an object held by a viewer is a photographing apparatus can be determined by whether the object held by the viewer has a reflection or not and the appearance of the object.
In implementations, the gestures of the viewer holding the camera device may include one-handed holding and two-handed holding. In general, in order to maintain stability of captured images and recorded videos, viewers hold both ends of a photographing apparatus with both hands to capture images or record videos.
In the embodiment of the invention, when the object held by the viewer is detected, whether the held object is the photographing device can be judged according to the distance between the two hands. The portable camera device is usually a smart phone, and the length of the smart phone is usually between 10 cm and 20 cm. Therefore, the target distance may be set to 10 cm in advance.
When the fact that the object is held by two hands of the audience is detected, and the distance between the two hands is larger than 10 cm, the fact that the object held by the hands is the photographic equipment can be judged.
It is understood that the set target distance may be other distance values, and may be set according to a specific application scenario.
When the audience holds the object by one hand, the size of the audience holding object can be obtained. 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 the photographic equipment.
In a specific implementation, when candidate audiences of the handheld photographic equipment are determined according to the image information of each audience, the posture information of each audience can be obtained according to the image information of each audience. And determining the behavior information of each audience according to the posture information of each audience within the preset time length. 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 posture 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 posture information of the audience in the preset time length. The preset time length can be set according to a specific application scene and application requirements. For example, the preset time length is 10 s. In another example, the predetermined time period is 20 s.
When the two hands of the audience are detected to be lifted within the preset time span and the audience holds the photographic equipment, the behavior information of the audience can be determined to be the picked-up photographic equipment, and therefore the audience can be determined to be the candidate audience.
When the audience is detected to be lifted by one hand within the preset time length and the camera equipment is held in the lifted hand, the behavior information of the audience can be determined to be the picked-up camera equipment, so that the audience can be determined to be the candidate audience.
In an implementation, the viewer may place the camera device beside the seat and fix the camera device, and perform unauthorized recording by adjusting the placement angle of the camera device. For example, in a movie theater, an armrest is often provided beside the seats of the audience, the armrest including a body portion and a cup holder for holding a beverage. The viewer places the photographic equipment in the cup holder beside the seat.
In view of 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 reflection phenomenon, it may be determined that the audience corresponding to the certain seat is a candidate audience. After the candidate audience is determined, the vertical angle of the photographic equipment relative to the ground may be obtained. When the vertical angle of the photographing apparatus with respect to the ground is within a preset angle range, the candidate viewer may be determined to be the target viewer. 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 are not described herein again.
In specific implementation, after the reminding device is controlled to output the reminding signal, the control signal can be output to a preset infrared light emitting device; or after the warning signal is output by the control reminding device, the control signal is output to the preset infrared light emitting device.
The infrared light emitting device may generate and emit infrared light after receiving the control signal. The infrared light emitting device may emit the generated infrared light toward a stage or a screen of the performance place. Since infrared light is invisible to human eyes and visible to a camera, a video image photographed by a photographing apparatus is disturbed by the infrared light.
The infrared light emitting means may also emit the generated infrared light toward a position where the target audience is located to interfere with the photographing apparatus held by the target audience.
By controlling the infrared light emitting device to emit infrared light, the interference to the camera equipment for unauthorized recording of the performance content can be realized, and the copyright of the performance content can be further protected.
