Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

It will be understood that the terms "first", "second" and the like used in this application may be used herein to describe various elements, but these elements are not limited by these terms unless otherwise specified. These terms are only used to distinguish a first element from another element. For example, a first xx script could be referred to as a second xx script, and similarly, a second xx script could be referred to as a first xx script, without departing from the scope of this application.

As shown in FIG. 1, in one embodiment, a video material marking method is proposed, and the video material marking method may specifically include the following steps:

Step S202, acquiring target material and target information corresponding to the target material.

In this embodiment of the present application, the target material is a picture or a video clip that constitutes a video. The target information corresponding to the target material may include information such as the designer of the target material, the type of the target material, the size of the target material, and the generation time of the target material, but is not limited thereto. In the process of video production, after the designer has finished designing the target material of the video, he can upload the target material and the target information corresponding to the target material to the computer equipment database, so that the computer equipment can obtain the target material and the corresponding target material according to the user's input. target information. It should be noted that this embodiment does not limit the specific classification method of the types of target materials. For example, the types of general target materials are divided into picture categories and video categories, wherein pictures include large pictures, splash screens, graphic flashes, etc. , the video includes the title, oral broadcast, plot, etc.

Step S204, determining the marking character string according to the target information;

In this embodiment of the present application, the marked character string is a character string added to the target material. This embodiment does not limit the specific method for determining the marking string according to the target information. For example, as shown in FIG. 2 , step S204 may include the following steps:

Step S302, generating a Long type ID according to the target information.

In this embodiment of the present application, the target information corresponding to the target material generates a unique Long type ID. This embodiment does not limit the specific method for generating the Long type ID according to the target information. For example, after receiving a target information, the database of the computer device can randomly generate an ID of the self-incrementing Long type, that is, the primary key ID. The Long type ID can be 15817. And each target material corresponds to a unique Long type ID.

Step S304, converting the Long type ID into a character string with a preset length to obtain the marking character string.

In this embodiment of the present application, there is no restriction on the length of the marking character string, for example, the character string with the preset length may be a character string composed of 4 characters. The marking string can be composed of 4 bits of 52 characters of "AaBbCDdEeFfGgHhiJjKLlMmNnOPpQqRrSTtUVWXYyZ2346789#+?". And the marking string corresponding to each target material is unique. This embodiment does not limit the specific method for converting the Long type ID into a character string with a preset length. For example, when the character string with the preset length is a character string with a length of 4 digits, the conversion from decimal to 52 can be used. Algorithm to convert the Long type ID into a 4-digit string. For example, the Long type ID is 15817, and the 4-digit length string converted by the algorithm of decimal to 52 is AdJK.

In the embodiment of the present application, when the generated ID of the Long type is 1 and the length of the converted character string is less than 4 digits, the character "A" can be used to make up 4 digits in front. Therefore, the ID of the Long type is 1 , the string obtained by the algorithm of decimal to 52 is "AAAa". When there are less than 4 digits, the string is supplemented to 4 digits, which can facilitate the unification of the algorithm and facilitate subsequent unified identification.

Step S206, generating the marking string watermark on the target material.

In the embodiment of the present application, when the target material is a picture, the marking string watermark is added to the picture. When the target material is video, the marking string watermark can be added to the picture of the video frame. When the target material is a video, the video frame data of the video can be obtained before generating the marking string watermark.

In the embodiments of the present application, there is no limitation on the specific method for generating the marking string watermark on the target material, for example, a third-party plug-in "FFMpeg" may be used.

In the embodiment of the present application, it should be noted that, in order to facilitate the subsequent identification of the marking string watermark, and to prevent the string watermark from affecting the content of the target material, the color of the marking string watermark is generally selected to be a color that can clearly distinguish the background of the target material. And add the marking string to the background area of the material. Therefore, as shown in FIG. 3 , step S206 may specifically include the following steps:

Step S402, identifying the background area and background color of the target material.

In the embodiment of the present application, an image recognition algorithm can be used to identify the target in the target material, and the area outside the target in the picture is the background area, thereby obtaining the background area. Get the RGB value of the pixel block in the background area of the picture, so that you can get the background color. The method of identifying the background area and background color of the target material is not limited to this.

Step S404, determining the color of the marking string according to the background color.

In this embodiment of the present application, the colors of the marking strings corresponding to different background colors may be preset. For example, a dark background may correspond to a light-colored marking string, and conversely, a light-colored background may correspond to a dark marking string. After obtaining the RGB value of the background of the target material, the color of the marking string can be determined according to the preset colors of the marking string corresponding to different background colors.

Step S406, adding the marking character string to the background area.

In the embodiment of the present application, there is no limit to the number of marking strings added to the background area. For example, only one marking string may be added, or the marking strings may be added uniformly to the background area according to a certain density.

In the embodiment of the present application, the target material with the marked string can be synthesized into a video subsequently, and then released.

In a video material marking method provided by an embodiment of the present application, by acquiring a target material and target information corresponding to the target material, then obtaining a marking string according to the target information, and then generating a watermark corresponding to the marking string on the target material, Therefore, automatic marking of target materials can be realized, manual marking is avoided, marking efficiency is improved, and labor costs are reduced. And subsequently, the information of the video material can be obtained according to the marking string watermark on the material in the video.

As shown in FIG. 4 , in another embodiment of the present application, a method for identifying a video material is also provided, which is used to identify a material marked by the above-mentioned video material marking method, and the video material identification method includes:

Step S502, cutting the video material to obtain a picture set with the size of the watermark area marked with the character string.

In this embodiment of the present application, the specific method for cutting the video material is not limited in this embodiment. For example, a region-based segmentation method may be used to cut according to the size of the watermark area of the marking string. The video material is a picture or a video. When the video material is a picture, the video material can be cut directly. Based on the size of the watermark area of each marked string, each picture in the video material can be cut into several pictures of the size of the marked watermark area, so as to obtain a set of pictures of the size of the marked string watermark area. . When the video material is a video, the video frame image of the video can be obtained first, and by cutting each video frame image, the video material can be cut into several videos of the size of the marked string watermark area to obtain a video collection, and then from the video collection The specified frame picture is intercepted in each preset unit duration of , to obtain the picture set. For example, if the preset unit duration is 1 second, and the specified frame picture is 2 frames of pictures, then 2 frames of pictures are intercepted from each second of video in the video collection, and the video frame picture that is finally intercepted constitutes the picture collection.

Step S504, identifying pictures in the picture set, and determining a character string set.

In the embodiment of this application, there is no restriction on the specific method of identifying the pictures in the picture collection. For example, a third-party identification tool "easyocr" can be used. This third-party tool provides an identification method. We only need to pass the picture address and Coordinates, size, the tool will automatically recognize the string on the picture.

Step S506, converting the string set into a Long type id set.

In this embodiment of the present application, a set of strings can be converted into a set of Long type ids by using an algorithm of converting from 52 to decimal. For example, a string set such as AdJa, Adla, AdJK is identified from a video, and the string set is converted into a Long type id set by an algorithm, such as: 15801, 15951, 15817.

In the embodiment of the present application, it should be noted that after the string set is obtained, the string set needs to be converted and filtered, for example, the strings whose length is not 4 digits in the string set are filtered out, and Lowercase letters such as "o, u, c" and characters similar to uppercase letters are uniformly converted to uppercase. Then, deduplicate the converted and filtered string collection, and finally convert the deduplicated string collection into a Long type id collection.

Step S508: Identify the video material according to the Long type id set.

In this embodiment of the present application, the target information corresponding to the Long type id can be searched in the database of the computer device through the Long type id in the Long type id set, thereby identifying the information of the video material.

In the video material identification method provided by the embodiment of the present application, when the video material is generated by the above-mentioned video material marking method, target information corresponding to the video material can be identified by the video material identification method. In this way, the video creation can be better protected and the video material can be prevented from being stolen.
