背景技术Background technique
视频拼接是指将多个视频文件或者视频的多个片段拼接成一个视频的过程。在相关技术中，通常采用直接选取多个视频，并将视频按照用户定义的顺序或者随机顺序进行拼接得到最终的拼接视频。Video splicing refers to the process of splicing multiple video files or multiple segments of a video into one video. In the related art, multiple videos are usually selected directly, and the videos are spliced in a user-defined order or a random order to obtain a final spliced video.
在对多个视频进行拼接时，如果不对多个视频进行预处理，可能会出现不同类型的视频合并在一起的情况，这种情况下可能会导致反差较大的视频相互拼接，造成拼接视频违和感强的问题。为了降低拼接视频的违和感，用户需要针对进行拼接的多个视频进行反复播放、裁剪、截取等操作，还需要针对拼接视频中的各部分添加音乐、滤镜、转场效果等。然而，在这种拼接方式中，需要用户进行大量的手动编辑操作，视频拼接的效率较低，对非专业用户非常不友好。When splicing multiple videos, if the multiple videos are not preprocessed, different types of videos may be merged together. In this case, videos with large contrast may be spliced to each other, resulting in illegal splicing of videos. and strong issues. In order to reduce the sense of violation of the spliced video, users need to repeatedly play, crop, and intercept multiple videos to be spliced, and also need to add music, filters, transition effects, etc. to each part of the spliced video. However, in this splicing method, users are required to perform a large number of manual editing operations, the efficiency of video splicing is low, and it is very unfriendly to non-professional users.
需要说明的是，在上述背景技术部分公开的信息仅用于加强对本公开的背景的理解，因此可以包括不构成对本领域普通技术人员已知的现有技术的信息。It should be noted that the information disclosed in the above Background section is only for enhancement of understanding of the background of the present disclosure, and therefore may contain information that does not form the prior art that is already known to a person of ordinary skill in the art.

The same reference numerals in the drawings denote the same or similar parts, and thus their repeated descriptions will be omitted. Some of the block diagrams shown in the figures are functional entities that do not necessarily necessarily correspond to physically or logically separate entities.

针对上述的现有技术所存在的缺点和不足，本示例实施方式中提供了一种视频拼接方法，可以应用于手机、平板电脑、数码相机等终端设备。In view of the above-mentioned shortcomings and deficiencies of the prior art, this exemplary embodiment provides a video splicing method, which can be applied to terminal devices such as mobile phones, tablet computers, and digital cameras.
图1示出了本示例性实施方式的一种流程，可以包括以下步骤S110至S130：FIG. 1 shows a flow of this exemplary embodiment, which may include the following steps S110 to S130:
步骤S110，响应于接收到待处理路径，根据预设分类策略对所述待处理路径中包括的视频文件进行分类，以获取至少一个拼接素材组。Step S110, in response to receiving the to-be-processed path, classify the video files included in the to-be-processed path according to a preset classification strategy to obtain at least one splicing material group.
在本公开的一种示例实施例中，在接受到待处理路径后，可以根据预设分类策略对待处理路径中的所有视频文件进行分类，进而获取至少一个拼接素材组。其中，每个拼接素材组中包括的素材的类型相同。In an exemplary embodiment of the present disclosure, after receiving the to-be-processed path, all video files in the to-be-processed path can be classified according to a preset classification strategy, and then at least one splicing material group is obtained. The types of materials included in each spliced material group are the same.
在本公开的一种示例实施例中，预设分类策略可以包括时长阈值和片段分类策略。此时，根据预设分类策略对所述待处理路径中包括的视频文件进行分类，参考图2所示，可以包括如下步骤S210至S230：In an exemplary embodiment of the present disclosure, the preset classification strategy may include a duration threshold and a segment classification strategy. At this time, the video files included in the to-be-processed path are classified according to a preset classification strategy. Referring to FIG. 2 , the following steps S210 to S230 may be included:
步骤S210，对所述视频文件进行扫描识别，以获取所述视频文件中各帧图像对应的图像标签。Step S210: Scan and identify the video file to obtain image tags corresponding to each frame of image in the video file.
在本公开的一种示例实施例中，在对视频文件进行分类之前，需要获取视频文件中各帧图形对应的图像标签，以根据图像标签对视频文件进行分类。因此，可以先对视频文件进行扫描识别，以获取视频文件中各帧图像对应的图像标签。其中，对视频文件的扫描识别可以根据机器学习模型或者神经网络模型进行，进而得到各帧图像对应的图像标签。In an exemplary embodiment of the present disclosure, before classifying a video file, an image label corresponding to each frame of graphics in the video file needs to be obtained, so as to classify the video file according to the image label. Therefore, the video file can be scanned and identified first, so as to obtain the image tags corresponding to each frame image in the video file. The scanning and identification of the video file can be performed according to a machine learning model or a neural network model, and then image labels corresponding to each frame of image are obtained.
需要说明的是，图像标签可以根据不同的拼接环境进行设定。例如，在普通用户的拼接环境中，可以设定图像标签包括人物、动物、风景、地点等；而在专业用户的拼接环境中，可以将图形标签设定的更为详细，例如，可以将风景进一步细化为城市风景、自然风景等，本公开对图像标签的设定不做特殊限制。It should be noted that the image label can be set according to different splicing environments. For example, in the splicing environment of ordinary users, the image tags can be set to include people, animals, landscapes, locations, etc.; while in the splicing environment of professional users, the graphics tags can be set in more detail, for example, the landscape can be set to It is further refined into urban landscapes, natural landscapes, etc. The present disclosure does not impose special restrictions on the setting of image tags.
步骤S220，在所述视频文件的时长大于所述时长阈值时，基于所述图像标签，根据所述片段分类策略对所述视频文件进行分类。Step S220, when the duration of the video file is greater than the duration threshold, classify the video file according to the segment classification strategy based on the image tag.
在本公开的一种示例实施例中，由于较长的视频文件有可能同时拍摄有多个类型的视频，例如在同一视频中可能同时拍摄有人物、宠物和风景等。因此可以针对不同长度的视频采用不同的分类方法。In an exemplary embodiment of the present disclosure, due to a long video file, it is possible to capture multiple types of videos at the same time, for example, people, pets, and landscapes may be captured simultaneously in the same video. Therefore, different classification methods can be used for videos of different lengths.
在本公开的一种示例实施例中，可以设置时长阈值，以根据视频文件的时长确定其分类策略。具体的，可以在视频文件的时长大于时长阈值时，选择片段分类策略，基于视频文件中各帧图像对应的图像标签对视频文件进行分类。In an exemplary embodiment of the present disclosure, a duration threshold may be set to determine a classification policy of a video file according to its duration. Specifically, when the duration of the video file is greater than the duration threshold, a segment classification strategy may be selected, and the video file may be classified based on the image tags corresponding to each frame of image in the video file.
在本公开的一种示例实施例中，片段分类策略可以包括片段分割策略。此时，参考图3所示，基于所述图像标签，根据所述片段分类策略对所述视频文件进行分类，可以包括如下步骤S310至S320：In an example embodiment of the present disclosure, the segment classification strategy may include a segment segmentation strategy. At this time, referring to FIG. 3 , based on the image tag, classifying the video file according to the segment classification strategy may include the following steps S310 to S320:
步骤S310，基于所述图像标签，根据所述片段分割策略将所述视频文件划分为至少一个视频片段，并确定所述视频片段对应的片段标签。Step S310, based on the image tag, divide the video file into at least one video segment according to the segment segmentation strategy, and determine a segment tag corresponding to the video segment.
在本公开的一种示例实施例中，可以基于视频文件中各帧图像对应的图像标签，根据片段分割策略将视频文件划分为视频片段，再针对每个视频片段确定对应的片段标签。举例而言，参考图4所示，基于所述图像标签，根据所述片段分割策略将所述视频文件划分为至少一个视频片段，并确定所述视频片段对应的片段标签，可以包括如下步骤S410至S420：In an exemplary embodiment of the present disclosure, the video file may be divided into video segments according to a segment segmentation strategy based on image labels corresponding to each frame of images in the video file, and a corresponding segment label may be determined for each video segment. For example, referring to FIG. 4 , based on the image tag, the video file is divided into at least one video segment according to the segment segmentation strategy, and the segment tag corresponding to the video segment is determined, which may include the following step S410 To S420:
步骤S410，根据各帧图像在所述视频文件中的顺序对所述图像标签进行排序，得到标签序列。Step S410: Sort the image tags according to the sequence of each frame of images in the video file to obtain a tag sequence.
在本公开的一种示例实施例中，可以先对根据视频文件中各帧图像的排列顺序，对对应的图像标签进行排序，得到一组按顺序排列的图像标签，即标签序列。例如，假设某一视频文件的前3帧图像对应的图像标签均为人物、动物、风景，则这3帧图像得到的标签序列为人物、动物、风景。In an exemplary embodiment of the present disclosure, the corresponding image tags may be sorted according to the arrangement order of each frame of images in the video file to obtain a set of sequentially arranged image tags, that is, a tag sequence. For example, assuming that the image tags corresponding to the first 3 frames of images of a certain video file are all people, animals, and landscapes, the sequence of tags obtained from these 3 frames of images is people, animals, and landscapes.
步骤S420，基于所述标签序列，根据片段分割策略对所述视频文件进行分段，以获取至少一个视频片段和对应的片段标签。Step S420: Based on the tag sequence, segment the video file according to a segment segmentation strategy to obtain at least one video segment and a corresponding segment tag.
在本公开的一种示例实施例中，在根据片段分割策略对视频文件进行分段时，片段分割策略可以包括预设数量和预设比例。举例而言，参考图5所示，基于所述标签序列，根据片段分割策略对所述视频文件进行分段，以获取至少一个视频片段和对应的片段标签，可以包括如下步骤S510至步骤S520：In an exemplary embodiment of the present disclosure, when segmenting a video file according to a segment segmentation strategy, the segment segmentation strategy may include a preset number and a preset ratio. For example, referring to FIG. 5 , based on the tag sequence, the video file is segmented according to a segment segmentation strategy to obtain at least one video segment and a corresponding segment tag, which may include the following steps S510 to S520:
步骤S510，在所述标签序列中截取目标标签序列，并根据所述目标标签序列将视频文件中对应的部分确定为一个视频片段。Step S510, intercept the target tag sequence from the tag sequence, and determine the corresponding part in the video file as a video segment according to the target tag sequence.
在本公开的一种示例实施例中，目标标签序列包括预设数量的图像标签，并且预设数量的图像标签中目标图像标签所占的比例大于等于预设比例。其中，预设数量和预设比例可以根据不同需求进行不同的设置，但通常情况下，可以将预设数量设置为较小的值，以便于对视频文件进行分段；将预设比例设置为较小的值，以保证目标标签序列对应的视频片段不包括多个类型的视频。例如，预设数量为1000，预设比例为70％，目标标签序列为标签序列中连续的1000帧图像标签，且1000帧图像标签中有大于等于700帧的图像标签相同。In an exemplary embodiment of the present disclosure, the target tag sequence includes a preset number of image tags, and a proportion of the target image tags in the preset number of image tags is greater than or equal to a preset ratio. Among them, the preset number and preset ratio can be set differently according to different needs, but in general, the preset number can be set to a small value to facilitate segmenting the video file; the preset ratio is set to A smaller value ensures that the video segment corresponding to the target tag sequence does not include multiple types of videos. For example, the preset number is 1000, the preset ratio is 70%, the target label sequence is 1000 consecutive frames of image labels in the label sequence, and 700 or more of the 1000 frame image labels have the same image label.
在本公开的一种示例实施例中，可以根据目标标签序列将视频文件中对应的部分确定为一个视频片段。具体的，可以将目标标签序列中各图像标签对应的各帧图像对应的视频截取出来，作为一个视频片段。通过在标签序列中确定目标标签序列，可以将较长的视频文件划分为不同类型的视频片段，以便于用户可以根据视频片段进行同类型的视频拼接。In an exemplary embodiment of the present disclosure, the corresponding part in the video file may be determined as a video segment according to the target tag sequence. Specifically, the video corresponding to each frame of image corresponding to each image tag in the target tag sequence may be cut out as a video segment. By determining the target tag sequence in the tag sequence, a long video file can be divided into different types of video clips, so that the user can perform video splicing of the same type according to the video clips.
步骤S520，将所述目标标签序列对应的目标图像标签，确定为所述目标标签序列确定的视频片段对应的片段标签。Step S520: Determine the target image label corresponding to the target label sequence as the segment label corresponding to the video segment determined by the target label sequence.
在本公开的一种示例实施例中，由于在目标标签序列中，目标图像标签所占的比例大于等于预设比例，因此可以将目标图像标签作为目标标签序列确定的视频片段对应的片段标签。例如，在目标标签序列中1000帧图像标签中有大于等于700帧的图像标签为人物时，可以将人物作为目标标签序列确定的视频片段对应的片段标签。In an exemplary embodiment of the present disclosure, since the proportion of the target image label in the target label sequence is greater than or equal to a preset ratio, the target image label can be used as the segment label corresponding to the video segment determined by the target label sequence. For example, when the image tags of 1000 frames of image tags in the target tag sequence are larger than or equal to 700 frames are people, the person can be used as the segment tag corresponding to the video segment determined by the target tag sequence.
步骤S320，基于所述片段标签对所述片段标签对应的视频片段进行分类。Step S320: Classify the video segment corresponding to the segment label based on the segment label.
在本公开的一种示例实施例中，由于片段标签是通过视频片段中占比较大的图像标签确定的，因此可以基于片段标签对视频片段进行分类，将具有相同片段标签的视频片段划分为同一类型，进而得到对应的拼接素材组。In an exemplary embodiment of the present disclosure, since the segment label is determined by the image label with a larger proportion in the video segment, the video segment can be classified based on the segment label, and the video segments with the same segment label are divided into the same segment label. type, and then obtain the corresponding stitching material group.
步骤S230，在所述视频文件的时长小于等于所述时长阈值时，基于所述图像标签对所述视频文件进行分类。Step S230, when the duration of the video file is less than or equal to the duration threshold, classify the video file based on the image tag.
在本公开的一种示例实施例中，在视频文件的时长小于等于时长阈值时，可以直接对视频文件进行分类。参考图6所示，基于所述图像标签对所述视频文件进行分类，可以包括如下步骤S610至S620：In an exemplary embodiment of the present disclosure, when the duration of the video file is less than or equal to the duration threshold, the video file may be directly classified. Referring to FIG. 6 , classifying the video file based on the image tag may include the following steps S610 to S620:
步骤S610，将所述视频文件对应的图像标签中，出现次数最多的最多图像标签确定为所述视频文件对应的文件标签。In step S610, among the image tags corresponding to the video file, the image tag with the most occurrences is determined as the file tag corresponding to the video file.
在本公开的一种示例实施例中，在视频文件对应的图像标签中，出现次数最多的图像标签可以代表视频文件的属性信息，因此可以将出现次数最多的最多图像标签确定为视频文件对应的文件标签。In an exemplary embodiment of the present disclosure, among the image tags corresponding to the video file, the image tag with the most occurrences may represent attribute information of the video file, so the image tag with the most occurrences may be determined as the image tag corresponding to the video file. file label.
步骤S620，根据所述文件标签对对应的所述视频文件进行分类。Step S620, classifying the corresponding video files according to the file tags.
在本公开的一种示例实施例中，可以根据文件标签对视频文件进行分类，进而将相同文件标签的视频文件划分为同一类型，得到对应的拼接素材组。In an exemplary embodiment of the present disclosure, the video files can be classified according to the file tags, and then the video files with the same file tag are divided into the same type to obtain the corresponding splicing material groups.
需要说明的是，在待处理路径中同时包括时长大于预设时长和小于等于预设时长的视频文件时，可以将相同类型的视频片段与视频文件合并在同一拼接素材组内，得到待处理路径中所有视频文件的分类结果。It should be noted that, when the to-be-processed path includes video files with a duration greater than or equal to the preset duration and less than or equal to the preset duration, video clips and video files of the same type can be combined into the same splicing material group to obtain the to-be-processed path.
