The method at least comprises the following steps:
step 401, the terminal collects a scene image of a target playing scene.
The terminal has an image acquisition function. The target play scene refers to a spatial scene for playing the target media data.
The terminal acquires scene images of a target playing scene through an image acquisition assembly, wherein the number of the scene images can be one; alternatively, there may be a plurality of images, and the number of scene images is not limited in this embodiment.
Optionally, the terminal may acquire the scene image every preset time; or acquiring a scene image when an acquisition instruction is received; or, collecting a scene image when detecting an optical signal with a brightness value higher than a preset brightness value; the embodiment does not limit the timing of acquiring the scene image by the terminal.
In step 402, the terminal determines whether the scene image includes a device image of an external photographing device.
The external photographing device refers to a photographing device that is not authorized by the owner of the target media data.
Optionally, the terminal matches the scene image with a template image of an external shooting device; when the matched scene image comprises the template image, determining that the scene image comprises the device image, and executing step 403; when the matched scene image does not include the template image, it is determined that the scene image does not include the device image, and step 401 is executed again or the flow ends.
The template image of the external photographing apparatus is pre-stored in the terminal. The template image is composed of features of the externally captured image, such as: the mobile phone is characterized in that the edge area of the rectangular block comprises a shooting small hole, the middle area of the rectangular block comprises a circular area, and the outside of the circular area is connected with the rectangular block.
Alternatively, the template image may be a two-dimensional image; alternatively, the image may be a Three-dimensional (3D) image, or may be a more multidimensional image, which is not limited in this embodiment.
Optionally, when the terminal matches the scene image with the template image of the external shooting device, the scene image may be divided into a plurality of rectangular blocks; matching the image content in each rectangular block with the template image; when the matching degree between the image content and the template image is greater than a preset value, determining that the scene image comprises an equipment image; and when the matching degrees between the image contents in all the rectangular blocks and the template images are less than or equal to a preset value, determining that the scene image does not comprise the device image.
The preset values are pre-stored in the terminal, and the preset values may be 80%, 90%, 98%, and the like, and the value of the preset value is not limited in this embodiment.
On the other hand, whether the scene image includes the device image of the external shooting device may also be determined in an artificial intelligence recognition manner, which specifically may be: by collecting samples containing device images of various types of external shooting devices, a neural network model which can be used for identifying the device images of the external shooting devices is trained, and the device images in the scene images are identified by using the model.
In step 403, the terminal generates a detection result notification when determining that the scene image includes the device image.
The detection result notification is used for the media management system to process the target media data.
The detection result notification may include a detection result in which the terminal determines that the scene image includes the device image. Optionally, the detection result notification may further include a device type of the external shooting device corresponding to the device image, such as: and when the terminal matches the image content identical to the template image of the mobile phone in the scene image, carrying the device type 'mobile phone' in the detection result notification.
In step 404, the terminal sends a notification of the detection result to the media management system.
The media management system is used for controlling the playing equipment to play the target media data.
Step 405, the media management system obtains a detection result notification sent by the terminal.
The detection result notification is generated when the terminal determines that the scene image of the target playing scene includes the device image of the external shooting device.
In step 406, the media management system obtains the shooting right of the target media data.
Optionally, the shooting authority includes an authority for allowing shooting and an authority for forbidding shooting, and of course, the shooting authority may be further divided, for example: the shooting permission prohibition is divided into a weak prohibition permission and a strong prohibition permission, and the setting mode of the shooting permission is not limited in the embodiment.
Step 407, the media management system processes the detection result notification according to the shooting authority.
Illustratively, the shooting right indicates that the target media data is allowed to be shot by the external shooting device, and the media management system ignores the detection result notification; or the shooting authority indicates that the target media data is forbidden to be shot by the external shooting equipment, and the media management system controls the playing terminal to output an external shooting prompt; or the media management system controls the playing terminal to stop playing the target media data. Such as: when the shooting authority is the weak forbidding authority, the media management system controls the playing terminal to output an external shooting prompt; and when the shooting right is a strong forbidding right, the media management system controls the playing terminal to stop playing the target media data.
When the media management system controls the play terminal to output the external shooting prompt, the play terminal can play the external shooting prompt on the top of the target media data in a rolling mode (in a bullet screen mode); alternatively, the external shooting prompt may be continuously displayed at the bottom of the target media data, and the display mode of the external shooting prompt is not limited in this embodiment.
The external photographing prompt is used for prompting that at least one external photographing device exists for photographing the target media data. Optionally, the external photographing prompt includes a device type of the external photographing device photographing the target media data.
In summary, in the identification method of the external shooting device provided by this embodiment, a terminal with an image capture function is used to capture a scene image of a target playing scene; determining whether the scene image includes a device image of an external photographing device; generating a detection result notification when it is determined that the scene image includes the device image; sending a detection result notification to the media management system, wherein the detection result notification is used for the media management system to process the target media data; the problem that the target media data is not high in safety because external shooting equipment cannot be prevented from shooting the target media data when information such as watermarks and copyrights is added to the target media data can be solved; the terminal acquires the scene image of the target playing scene to identify whether the target playing scene comprises the external shooting equipment, so that the external shooting equipment can be identified, and the safety of the target media data is improved.
Alternatively, since the external photographing apparatus may not photograph the target media data when the external photographing apparatus is included in the scene image, in order to improve the accuracy of the terminal in identifying the external photographing apparatus that photographs the target media data, referring to fig. 5, the identification method of the external photographing apparatus provided by the present application further includes the following steps, based on the above-described embodiment, as an alternative step to step 403,
step 501, when the scene image comprises the device image, the terminal acquires a target position of the device image in the scene image.
And 502, the terminal determines the shooting probability of shooting the target media data by the external shooting equipment according to the target position.
At this time, the detection result notification includes the shooting probability.
The method comprises the steps of determining that the shooting probability is larger than or equal to a first probability value when a target position is within a first preset range of a scene image; when the target position is within a second preset range of the scene image, determining that the shooting probability is greater than a second probability value and smaller than a first probability value; and when the target position is within a third preset range of the scene image, determining that the shooting probability is less than or equal to a second probability value.
The first preset range, the second preset range and the third preset range are determined according to the position relation between the terminal and the playing position of the target media data. Taking the target playing scene directly in front of the playing position of the target media data as an example, at this time, the shooting probability of the external shooting device located in the middle of the target playing scene is relatively high, so the first preset range may be a center region obtained by dividing the scene image into three parts from the center to the edge, the third preset range is an edge region after the division, and the second preset range is a region between the center region and the edge region.
The first probability value is greater than the second probability value, illustratively, the first probability value and the second probability value may be represented by percentages, such as: the first probability value is 90% and the second probability value is 60%; alternatively, it can be represented by a probability scale, such as: the first probability value is level 2, the second probability value is level 1 (the larger the number of levels is, the higher the corresponding probability is), and the present embodiment does not limit the representation and values of the first probability value and the second probability value.
Of course, the terminal may also divide the scene image into more regions, such as: 4 zones, 5 zones, etc.; or, divided into fewer regions, such as: 2 regions, the present embodiment does not limit the dividing manner and the number of the divided scene images.
Step 503, generating a detection result notification according to the shooting probability.
Optionally, the terminal generates a detection result notification when determining that the scene image includes the device image, and carries the shooting probability in the detection result notification; or the terminal generates a detection result notification when the scene image is determined to comprise the equipment image and the shooting probability is greater than the second probability value, and carries the shooting probability in the detection result notification; or the terminal generates a detection result notification when the scene image is determined to comprise the device image and the shooting probability is greater than or equal to the first probability value, and carries the shooting probability in the detection result notification.
In summary, according to the identification method of the external photographing apparatus provided by this embodiment, since the external photographing apparatus needs to be able to photograph the target media data at the specified position when the external photographing apparatus is used to photograph the target media data, by determining the photographing probability of the external photographing apparatus photographing the target media data according to the target position of the apparatus image in the scene image, the accuracy of the terminal identifying the external photographing apparatus that is photographing the target media data can be improved.
Alternatively, since some photographing elements are required when photographing the target media data using the external photographing apparatus, such as: therefore, in order to improve the accuracy of the terminal in identifying the external photographing device for photographing the target media data, referring to fig. 6, the method for identifying the external photographing device provided by the present application further includes the following steps, based on the above-mentioned embodiments, as an alternative step to step 403,
step 601, when the scene image comprises the device image, the terminal identifies whether the scene image comprises an element image of the external shooting device when shooting the target media data.
The elemental image refers to an imaging element required by the external imaging device when imaging the target media data. Illustratively, the elemental image includes, but is not limited to, at least one of the following:
at least one of a flash blinking image, a power lamp blinking image, and a shooting posture image.
Optionally, the corresponding elemental images of different types of external photographing devices are different, such as: the element images corresponding to the video recorder comprise a power lamp flickering image and a shooting posture image; the elemental images corresponding to the camera include a flash blinking image and a shooting posture image.
Wherein the flash flashing image or the power lamp flashing image can be determined according to at least two scene images. Such as: and determining that the two images are flash flickering images or power supply lamp flickering images when the luminance in the (i, j) th pixel of the nth scene image is x, the luminance in the (i, j) th pixel of the (n + 1) th scene image is y, and the x is different from the y, and the pixel content of the (i, j) th pixel of the (n + 1) th scene image is the same as the pixel content of the (i, j) th pixel of the nth scene image. Wherein n, i and j are positive integers.
The shooting posture image is determined according to the posture when the target media data is shot using an external shooting device, such as: a posture when the user photographs the target media data (such as arm flat or arm forming a diamond shape), a posture when the tripod photographs the target media data, and the like.
In step 602, the terminal generates a detection result notification when the scene image includes the element image.
