下面对本申请实施例中涉及到的技术关键词进行介绍。
图像美学评分：基于美学评分算法对图像进行评分。对于图像的美学评分算法，可以使用一些量化的图像美学规则，例如重要特征在所拍摄的图像的画面中的分布。这些美学评分规则可以来自于经验总结，常用的美学评分规则例如包括三分法、主对角线原则、视觉平衡、以及确定被拍摄主体占画面的比例等。基于不同的需求可以有不同的图像美学规则。根据每一种规则可以计算一个美学评分Ei。图像的最终的美学评分可以是根据任意一种规则所计算的美学评分，也可以是根据多个规则所计算的美学评分的加权平均，即E＝∑wiEi。其中wi表示权重。具体地，每种规则下的美学评分可以表示为Ei＝g(Si,Fi)，其中Si描述被拍摄主体的大小和位置，Fi描述主要特征在图像画面中的分布，g为自定义函数(例如高斯函数)。
视频美学评分：同理于图像美学评分，在视频中抽取图像帧，一个视频的美学评分可以是该视频中多个图像帧的美学评分的加权平均。
下面对本申请实施例涉及的应用场景进行举例说明。
手机可以基于相册中保存的图片或视频，对一段时间内或者一个主题下的图片或视频进行剪辑、拼接，自动生成一段新的视频(也可以称为vlog)，该新的视频可以是一段时间内的精彩回顾，例如周末的精彩回顾、节假日的精彩回顾等等；也可以是一个主题下的精彩瞬间，例如运动主题下的精彩瞬间、旅游主题下的精彩瞬间、毕业主题下的精彩瞬间等等。
在一些应用场景中，在用户驾驶汽车的过程中，汽车上的其他用户可以拍摄周边环境景色作为记录，若用户想要基于拍摄的图片或视频得到一个处理后的新的视频，需要手动进行剪辑、拼接；或者手机端可以自动生成。目前，手机端自动生成图片拼接视频的过程，是在充电灭屏时对用户相册的图片进行时间地点聚类、场景分类、美学评分后生成的。用户使用手机拍摄照片后，需要充电灭屏等待一段时间，等到对相册中的照片进行时间地点聚类、智慧化分类、生成艺术化封面完成后，可以获得一个由若干照片组成的图片视频。
具体的，如图1所示，图1示出了一种自动生成图片拼接视频的步骤流程。当电子设备检测到自身当前处于充电灭屏状态，电子设备将保存在相册中的照片进行分类，该分类的方式可以是基于时间和/或地点，基于时间分类例如可以是将电子设备在一周内保存的照片划为一类，或者将一个周末内保存的照片划为一类，基于地点分类例如可以是将电子设备在同一个地点保存的照片划为一类，基于时间和地点分类例如可以是将电子设备在一个周末内并且处于同一地点保存的照片划为一类。电子设备将划为一类的多个照片进行图片分析，对该多张照片进行去重以及基于算法进行打分，将重复率高的两张照片筛选掉一张，并且将打分低的照片筛选掉，得到最终的多张照片，将该多张照片进行排序，将多张照片中相同场景的照片排在一起，从而生成最终的图片拼接视频，该视频可以基于时间或场景命名，例如命名为“周末小时光”“周末那些事”等等。
其中，由于特殊场景或特殊时刻强依赖于智慧化能力，并且用户照片多为周末出游，生 成的相册视频多为无场景时刻视频。大量无场景时刻视频存在命名重复、单一的问题，并且上述方式需要在电子设备在充电灭屏的过程中完成，数据量大时，分析时间长，若有大量照片的情况下，用户等待时间久。
本申请实施例提供了一种视频生成方式，电子设备能够同步分析正在实时拍摄的视频，并对该视频进行剪辑，这样，能够解决上述场景中用户等待时间久的问题，在用户驾驶汽车的过程中，汽车上的其他用户可以拍摄周边环境景色作为记录，当记录的视频结束后，用户可以即时获取到剪接后的新的视频。

本申请实施例，电子设备101拍摄视频，电子设备100可以在电子设备101拍摄视频的过程中实时获取到视频数据，电子设备100对实时获取到的视频数据进行分析和剪辑。即电子设备101一边拍摄视频，电子设备100一边同步对该视频进行分析和剪辑，当电子设备101拍摄视频结束，电子设备100可得到剪辑完成的一个新的视频。这样，可以提高视频生成的效率，减少用户等待的时间。示例性的，电子设备100为车机，电子设备101可以为车载摄像头或手机等具有摄像头的设备。当用户驾驶着连接有电子设备101的车辆时，电子设备101可以实时拍摄驾驶过程中路边的风景，那么电子设备100可以对实时拍摄到的视频或图片同步进行分析和剪辑，驾驶结束后电子设备100即可生成一个关于驾驶过程中的旅行视频。并且电子设备100可以将生成的旅行视频分享到其他电子设备(包括电子设备101)。
在一些实施例中，电子设备100和电子设备101可以通过服务器进行数据通信，服务器用于为支持视频生成技术的应用程序提供后台服务。其中，服务器可以是应用服务器、云服务器、后台服务器等等。服务器还可以是云计算平台、虚拟化中心等，包括用于接入广域网的设备，例如基站，宽带远程接入服务器(broadband access serve，BRAS)、光网络单元、宽带网络业务网关(broadband network gateway，BNG)，汇聚交换机等。

电子设备100同步获取到电子设备101实时拍摄的视频，对获取到的视频进行画面选取，将选取到的画面作为最终生成的新视频中的一段内容。
如图5a所示，电子设备100同步获取到电子设备101拍摄到的视频画面，电子设备100对获取到的视频画面进行抽帧并基于美学评分算法进行评分，当检测到视频画面中的场景类型改变了，电子设备100确定上个场景中评分最高的视频段。然后继续对下个场景进行抽帧评分，直至结束。
本申请实施例，电子设备100通过滑动窗口实时选出评分最高的视频画面，这样电子设备100可以在满足第二预设条件时即生成第一视频，无需等待后台的长时间分析。并且，当电子设备100为车机的情况下，车机对功耗的要求更低，平均每帧分析消耗800-1000ms，节约资源。
在一些实施例中，电子设备100对获取到的视频数据进行分段，然后按照预设方式在分段后的每一段视频中选取部分画面。
进一步的，电子设备100对获取到的视频数据进行分段的分段方式可以是基于场景镜头进行分段，场景镜头包括人物镜头、风景镜头、转场镜头等等，如图5b所示，图5b示例性示出了电子设备101实时拍摄到的视频，电子设备100同步获取到电子设备101拍摄到的视 频，电子设备100基于图像识别技术对视频中的图像帧进行识别，从而划分出不同分类的镜头，图5b中示出了三类场景镜头，每类场景镜头对应一段视频，时间点1之前的视频中的图像帧分类为场景镜头1；时间点1和时间点2之间的视频中的图像帧分类为场景镜头2；时间点2之后的视频中的图像帧分类为场景镜头3。

可选的，画面选取的方式可以是将该段视频进行等间隔抽帧，如图5c所示，图5c中以场景镜头1为例，示例性示出了一个场景镜头进行画面选取的方式。图5c中，电子设备100在场景镜头1中抽出了9个图像帧，该9个图像帧把场景镜头1划分为了8段视频画面。电子设备100对该9个图像帧进行美学评分，确定出每个图像帧对应的评分，从而确定出每段视频画面的评分，可选的，每段视频画面的评分可以是两个图像帧的平均评分。例如视频画面1的评分为图像帧1和图像帧2的平均评分，视频画面2的评分为图像帧2和图像帧3的平均评分，以此类推。电子设备100选取出评分最高的一段视频画面作为最终生成的新视频中的一段内容。
可选的，电子设备100选取评分大于第四阈值的视频画面作为最终生成的新视频中的内容。这样可能会出现在一段场景镜头中没有选取到任何画面的情况，也可能会出现在一段场景镜头中选取了大量画面的情况。
在一些实施例中，美学评分的评分规则可以根据视频画面的场景类型的改变而改变。电子设备100每划分出一个视频段，则基于当前电子设备100的地理位置或者图像识别技术，确定该视频段的场景类型，从而确定该场景类型对应的评分规则。举例来说，用户在S101省道，该地地貌特征为丹霞地貌，美学评分规则中可以提高或加入色彩鲜艳程度和地形层次的权重；在千岛湖环湖公路，多为侵蚀剥蚀低山丘陵的库区地貌，美学评分规则中可以提高或加入水、岛、天空的占比的权重；在城市内部驾驶，如上海延安路高架，美学评分规则中可以提高或加入灯光鲜明程度，天空与高楼的占比的权重；等等。这样，根据精确的场景分类，进行定制化的美学评分规则，能够选出最贴近大众审美的画面片段，提升用户体验。
上述电子设备100对电子设备101实时拍摄的视频进行分析的过程，是随着电子设备101拍摄到的视频画面同步进行的，电子设备100同步接收到电子设备101拍摄的视频画面，对接收到的视频画面进行分段，每划分一段则截取一部分画面作为最终生成的新视频中的内容，直至电子设备100的地理位置信息满足第二预设条件，电子设备100生成第一视频。

分享控件811用于将第一视频发送到其他电子设备，或者分享到应用程序。
本申请实施例，电子设备100基于自身的地理位置确定对视频画面的分析开始和分析结束时间，当电子设备100的地理位置满足第一预设条件，电子设备100开始对电子设备101实时拍摄到的视频数据进行分析和剪辑。即电子设备101一边拍摄视频，电子设备100一边同步对该视频进行分析和剪辑。当电子设备100的地理位置满足第二预设条件，电子设备100生成第一视频，并不再对电子设备101之后拍摄到的视频数据进行分析和剪辑。该第一视频即为基于电子设备100获取到的视频内容进行分析并剪辑得到的。这样，电子设备100同步分析实时拍摄到的视频内容的方式，可以提高视频生成的效率，减少用户等待的时间。
示例性的，电子设备100为车机，电子设备101可以为车载摄像头或手机等具有摄像头的设备。当用户驾驶着搭载有电子设备100的车辆上时，电子设备101可以实时拍摄驾驶过程中路边的风景，那么电子设备100可以对实时拍摄到的视频数据或图片同步进行分析和剪辑，驾驶结束后电子设备100即可生成一个关于驾驶过程中的旅行视频。电子设备100可以将该视频发送到其他电子设备。
在一些应用场景中，电子设备100为车机，电子设备101可以为手机上的摄像头，手机可以实时拍摄驾驶过程中路边的风景，驾驶结束后电子设备100即可生成一个关于驾驶过程中的旅行视频。电子设备100可以将该视频发送到其他电子设备，例如手机上。
在一些应用场景中，电子设备100为手机，电子设备101可以为车载摄像头，车载摄像头可以实时拍摄驾驶过程中路边的风景，驾驶结束后手机即可生成一个关于驾驶过程中的旅行视频。
在一些实施例中，电子设备101包括多个电子设备。例如，电子设备100为车机，电子设备101可以为车载摄像头和手机上的摄像头，即电子设备100可以接收到多个电子设备101实时拍摄到的视频数据。可选的，电子设备100可以基于在同一段时间内获取到的多段视频数据进行分析，选取中多段视频中的多段视频内容拼接到一起。
上述实施例中均以电子设备101拍摄的是视频为例，不限于视频数据，电子设备101还可以拍摄图像，电子设备100可以同步获取到电子设备101实时拍摄到的图像数据。在一些实施例中，电子设备100获取电子设备101实时拍摄的图像数据。当电子设备100的地理位置满足第一预设条件，电子设备100开始对电子设备101实时拍摄到的图像数据进行分析和剪辑。即电子设备101一边拍摄图像，电子设备100一边同步对接收到的图像进行分析和剪辑。
示例性的，电子设备100对拍摄得到的一系列图像进行场景分类，在每个场景下的图像中选取部分图像作为最终生成的视频中的部分内容，选取方式包括例如基于美学评分算法筛选出评分较高的照片。进一步的，在进行美学评分之前，电子设备100基于图像识别技术筛选出重复率较高的照片，选取其中的一张或多张(例如为美学评分最高的一张)保留。
示例性的，电子设备100先确定需要的图像张数n张，电子设备100对接收到的每张图像进行美学评分，排名前n张的图像作为最终生成的视频中的内容。
当电子设备100的地理位置满足第二预设条件，电子设备100生成第一视频，并不再对电子设备101之后拍摄到的图像数据进行分析和剪辑。该第一视频即为基于电子设备100获取到的图像进行分析并剪辑得到的。这样，电子设备100同步分析实时拍摄到的图像的方式，可以提高视频生成的效率，减少用户等待的时间。
在一些实施例中，电子设备100可以获取电子设备101发送的图像数据和视频数据。当 电子设备100的地理位置满足第一预设条件，电子设备100开始对电子设备101实时拍摄到的图像数据和视频数据进行分析和剪辑。即电子设备101一边拍摄图像和视频，电子设备100一边同步对接收到的图像数据和视频数据进行分析和剪辑。当电子设备100的地理位置满足第二预设条件，电子设备100生成第一视频，并不再对电子设备101之后拍摄到的图像数据和视频数据进行分析和剪辑。
在上述实施例中，可以全部或部分地通过软件、硬件、固件或者其任意组合来实现。当使用软件实现时，可以全部或部分地以计算机程序产品的形式实现。所述计算机程序产品包括一个或多个计算机指令。在计算机上加载和执行所述计算机程序指令时，全部或部分地产生按照本申请实施例所述的流程或功能。所述计算机可以是通用计算机、专用计算机、计算机网络、或者其他可编程装置。所述计算机指令可以存储在计算机可读存储介质中，或者从一个计算机可读存储介质向另一个计算机可读存储介质传输，例如，所述计算机指令可以从一个网站站点、计算机、服务器或数据中心通过有线(例如同轴电缆、光纤、数字用户线)或无线(例如红外、无线、微波等)方式向另一个网站站点、计算机、服务器或数据中心进行传输。所述计算机可读存储介质可以是计算机能够存取的任何可用介质或者是包含一个或多个可用介质集成的服务器、数据中心等数据存储设备。所述可用介质可以是磁性介质，(例如，软盘、硬盘、磁带)、光介质(例如DVD)、或者半导体介质(例如固态硬盘)等。
