具体实施方式
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明实施例作进一步详细的说明。
本发明实施例提供的实现媒体对象显示的方法、装置及***，是针对现有技术中媒体对象显示不直观且查找困难的技术问题，提出在采集媒体对象时，记录下对应的采集位置以及采集姿态信息，在客户端呈现时，可以根据媒体对象的采集位置以及采集姿态选取各区域中稳定的图像或视频帧并在地图相应位置上显示，达到更优的媒体对象呈现效果。
本发明实施例提供的实现媒体对象显示的方法将从实现媒体对象显示的装置角度进行描述，该实现媒体对象显示的装置具体可以集成在客户端中，该客户端可以装载在终端中，该终端具体可以为智能手机、平板电脑、电子书阅读器、MP3(Moving Picture Experts Group Audio Layer III，动态影像专家压缩标准音频层面3)播放器、MP4(Moving Picture Experts Group Audio Layer IV，动态影像专家压缩标准音频层面4)播放器、膝上型便携计算机和台式计算机等等。
参见图1所示，是本发明实施例中提供的实现媒体对象显示的方法实施例一，可以包括以下步骤：
步骤101：获取采集得到的媒体对象，并获取媒体对象对应的采集位置以及采集姿态信息。
其中，所述媒体对象包括图像、视频及音频中的任意一种或多种的组合。且在获取采集到的媒体对象的同时，还可以一并获取媒体对象对应的采集位置以及采集姿态信息。
在使用媒体对象采集设备采集媒体对象的过程中，例如使用无人机航拍图片和/或视频的过程中，可以记录下媒体对象的采集位置，采集位置可 以使用GPS(Global Positioning System，全球定位***)信息进行标识，同时可以记录下媒体对象的采集姿态信息，采集姿态信息可以为惯性测量单元数据，惯性测量单元数据可以包括采集媒体对象时，采集设备三轴的姿态角，或角速率，以及加速度，用于代表媒体对象的采集姿态。进一步的，采集姿态信息还可以包括采集朝向、采集高度等信息。可以理解的是，当媒体对象为图像时，每一幅图像均可以有对应的采集位置与采集姿态信息；当媒体对象为视频时，则视频中每一视频帧均可以有对应的采集位置与采集姿态信息。
在本发明的一些实施例中，采集媒体对象的过程中，还可以记录采集轨迹信息，采集轨迹信息是指媒体对象采集设备的运动轨迹即采集轨迹，可以理解每个媒体对象的采集位置均分布在采集轨迹上。
请再参见图2所示，以无人机航拍为例，航拍设备在拍摄过程中，可以生成轨迹文件，记录一系列的时间、GPS信息以及惯性测量单元数据，如果进行媒体对象的采集，则同时把记录的GPS信息以及惯性测量单元数据写入到媒体对象的属性信息中，例如写入图像的Exif(Exchangeable Image File，可交换图像文件)信息，Exif信息中可以包括在拍摄过程中采集的一系列信息，Exif(信息可以嵌入到JPEG(Joint Photographic Experts Group，联合图像专家小组)/TIFF(Tagged Image File Format，标签图像文件格式)图像文件的头部。图2所示的航拍设备仅为示意作用，但不限定于此种航拍设备。
当用户需要使用装载在显示终端的客户端浏览媒体对象时，客户端需要首先获取采集得到的媒体对象以及媒体对象对应的采集位置和采集姿态信息，以便于后续步骤通过分析媒体对象的采集位置和采集姿态信息精选出一些媒体对象进行展示。
步骤102：从所述媒体对象中确定出满足预设条件的显示对象并获取所述显示对象对应的采集位置信息。
一般来说，显示终端的显示区域有限，如果媒体对象的数量较多则无 法同时全部显示，这样在客户端显示媒体对象时，则需要对媒体对象进行筛选，选取采集位置有一定间隔且采集姿态比较稳定的图像或视频帧作为精选呈现，采集姿态稳定一般代表图像质量更好。
其中，若媒体对象为图像集合时，将所述图像集合划分为至少一个子集合，若所述图像集合的子集合中所述图像的数量大于数量阈值，将子集合中满足预设条件的图像确定为显示对象；若所述若子集合中所述图像的数量小于或等于数量阈值，将子集合中全部所述图像确定为显示对象。
具体地，可以根据所述图像集合的采集位置及图像的分布密度确定出子集合的范围。若某区域采集位置的图像数量较多，即图像密度较大，则多划分几个子集合，相应地，图像密度较小的区域则少划分几个子集合。
具体的，即当媒体对象为图像集合时，如果每个子集合图像数量较少，且各图像的采集地点比较分散，即图像数量小于或等于数量阈值，且各图像之间的采集位置距离差值大于或等于距离阈值，则可以直接选择全部图像进行显示，否则，则需要将子集合中满足预设条件的图像确定为显示对象。其中，数量阈值以及距离阈值可以根据实际情况进行设定，本发明对此不进行限定。当媒体对象为视频时，则可以直接从视频中选取视频帧进行显示。
若所述媒体对象为视频时，可以从所述视频中选取满足预设条件的媒体片段作为显示对象并获取所述显示对象所对应的采集位置信息。其中，所述媒体片段可以为视频片段或视频帧。
此外，还可以获取采集轨迹信息，调用所述地图数据，根据所述采集轨迹信息在所述地图上显示采集轨迹。
当所述媒体对象为图像集合时，根据所述采集轨迹将所述图像集合划分为至少一个子集合，将所述子集合中满足预设条件的图像确定为显示对象。当所述媒体对象为视频时，从所述视频中选取满足预设条件的媒体片段作为显示对象并获取所述显示对象所对应的采集位置信息。
在本发明的一些实施例中，为了保证所确定出的显示对象具有较好的 显示效果，所述显示对象需满足预设条件。
具体的，当媒体对象为图像集合时，若所述图像集合的每一子集合上图像数目大于数量阈值，选取稳定性参数最大的图像或稳定性参数和兴趣点参数加权求和最大的图像作为显示对象。当媒体对象为视频时，即可以在所述视频中每隔预设时间截取一段视频片段或在所述视频中每隔预设时间确定出一个视频帧作为显示对象，所述显示对象为所述预设时间内稳定性参数最大的媒体对象或稳定性参数和兴趣点参数加权求和最大的媒体对象。
针对媒体对象为图像集合或视频等不同情况，在后续实施例中会对如何选取显示对象进行详细说明。
这样，可以从大量媒体对象中，选取分散且图像质量更好的图像或视频帧进行显示。
步骤103：调用地图数据，根据显示对象的采集位置，将显示对象显示在地图上。
显示对象是从媒体对象中选取获得的，即显示对象有对应的采集位置，进一步的，本发明实施例根据显示对象的采集位置在地图上的相应位置进行显示，显示对象在地图上的显示位置与显示对象的采集位置一致，使用户可以直观获得媒体对象的采集位置。
此外，还可以将显示对象和显示对象所对应的采集位置上传到云端等共享平台，以便其他用户可以查看，同时也便于查看同一地点其他用户共享的显示对象。
在本发明的一些实施例中，还可以获取采集轨迹信息，调用地图数据，根据采集轨迹信息在地图上显示采集轨迹。在地图上显示采集轨迹可以在步骤101、102、103任一步骤之前执行，对此不进行限定。
另，还可以对所述地图上显示的采集轨迹进行修改，使其呈现用户需要的形式，如改变采集轨迹的长短、路线等。
参见图3所示，是本发明实施例的一个显示结果示意图，使用的媒体 对象采集设备为无人机航拍设备，当用户使用客户端浏览媒体对象时，会读取轨迹文件里面的GPS信息，然后调用地图API(Application Programming Interface，应用程序接口)获取当前地图数据，根据轨迹文件记录的GPS数据将飞行轨迹在地图上绘制出来，然后读取媒体对象例如图像及其Exif数据，如果图像数量不多而且地点较为分散，那么就将图像的缩略图***对应的地图点上显示，如果图片数量较多或者比较集中，则可以选取分散且拍摄时的稳定性最高，即图片质量更高的图片安插在地图上显示。让用户可以直观看到图像或视频的内容及其在地图上的具***置，达到最佳的呈现效果。
另外，在本发明的一些实施例中，还可以在接收用户通过点击显示对象而输入的显示触发信号后，显示或播放显示对象以及在距显示对象的预设范围内的其他媒体对象。在地图上显示的是精选后的媒体对象，用户可以通过点击该媒体对象，即点击显示对象，来触发显示对象以及在距该媒体对象预设范围内的其他媒体对象。其中，预设范围可以是距离显示对象空间距离上的预设范围，也可以是距离显示对象拍摄时间上的预设范围，预设范围可以根据实际情况灵活设置。
这样，本发明实施例通过获取媒体对象以及对应的采集位置以及采集姿态信息，对采集位置以及采集姿态信息进行分析，筛选出采集位置有一定间隔，且采集姿态比较稳定的图像或视频帧作为精选并在地图相应位置上显示，使用户在查看媒体对象时，可以直观看到媒体对象与地理位置的关系，显示直观，且通过显示对象的索引可以更快确定查找内容的位置，极大方便了用户查阅。
以下通过三个不同的实施例，再对本发明实施例中提供的实现媒体对象显示的方法进行说明，其中重点说明如何从媒体对象中选取显示对象。
参见图4所示，是本发明实施例中提供的实现媒体对象显示的方法实施例二，当媒体对象为图像时，可以包括以下步骤：
步骤401：获取采集得到的图像集合。
步骤402：将所述图像集合划分为至少一个子集合。
在本实施例中仅对需要从媒体对象中选取显示对象的情况进行说明。 获取采集得到的图像集合，此图像集合对应的采集位置可以组成一个区域，根据所述图像集合的采集位置及图像的分布密度将所述图像集合划分为至少一个子集合，若某区域采集位置的图像数量较多，即图像密度较大，则多划分几个子集合，相应地，图像密度较小的区域则少划分几个子集合。所述子集合的选择条件可以为保证子集合中需要包括媒体对象。这里的子集合的数量以及子集合的形状、面积可以根据实际情况设定，本发明对此不进行限定。
步骤403：在仅获取到稳定性参数时，在每个子集合中选取采集稳定性参数最大的图像作为显示对象。
步骤404：在获取到稳定性参数以及兴趣点参数时，在每个子集合中选取由稳定性参数以及兴趣点参数加权求和最大的图像作为显示对象。
步骤403与步骤404之间是“或者”的关系，即这两个步骤是从每个子集合内选取显示对象的两种不同的实施方式。可以根据实际应该情况灵活选择仅获取稳定性参数，或获取稳定性参数以及兴趣点参数，可以理解的是，仅获取稳定性参数计算量小，而采用稳定性参数以及兴趣点两个参数共同参与显示对象的选择，选取的显示对象更贴近用户需求。
其中，稳定性参数是根据媒体对象对应的采集姿态信息确定的，具体的，稳定性参数可以根据媒体对象对应的采集姿态信息中包括的惯性测量单元数据确定，惯性测量单元数据代表采集媒体对象时的角速度或加速度，可以理解的是，在采集媒体对象时媒体对象采集设备的角速度或加速度越小则稳定性越高，在同等清晰度条件下采集稳定性高代表采集到的媒体对象质量更好。
而在本发明的一些实施例中，还可以根据媒体对象对应的采集姿态信息确定媒体对象的采集朝向；接收用户输入的兴趣点位置；根据媒体对象的采集位置、媒体对象的采集朝向以及兴趣点位置计算媒体对象的兴趣点参数。即兴趣点参数可以根据媒体对象的采集位置、媒体对象的采集朝向以及兴趣点位置计算确定，媒体对象的采集朝向可以根据媒体对象对应的 采集姿态信息确定，而兴趣点位置可以通过接收用户输入的兴趣点位置获取。
例如某图像采集位置为A点，用户设置的兴趣点位置为B点，如果此时采集朝向是由A点朝向B点，则采集到兴趣点图像的可能性很大，即为兴趣点参数较大。在实际应用中，兴趣点参数的计算方式很多，例如媒体对象的采集位置与兴趣点位置构成一条线段，由媒体对象的采集位置为起点沿采集朝向生成一条射线，则这条线段与这条射线之间小于180度的角度越小则兴趣点参数越大，另外还可以根据采集位置与兴趣点之间的距离确定兴趣点参数。总之，兴趣点参数可以代表媒体对象的内容中包括用户兴趣点信息的可能。
这样，在选取媒体对象时可以选取每个子集合内稳定性参数最大的图像作为显示对象；也可以将各个图像的稳定性参数与兴趣点参数加权求和，综合两个不同的指标，在每个子集合内选取加权求和最大的图像作为显示对象。
步骤405：调用地图数据，根据显示对象的采集位置，将显示对象显示在地图上，使显示对象在地图上的显示位置与显示对象的采集位置一致，或使显示对象在地图上的显示位置与显示对象的采集位置之间的距离在预设范围之内。
本步骤与步骤103类似，在此不再赘述。
参见图5所示，是本发明实施例中提供的实现媒体对象显示的方法实施例三，当媒体对象为图像时，可以包括以下步骤：
步骤501：获取采集得到的图像集合。
步骤502：根据所述采集轨迹将所述图像集合划分为至少一个子集合。
在本实施例中仅对需要从媒体对象中选取显示对象的情况进行说明。获取采集得到的图像集合，此图像集合对应的采集位置可以组成一个区域，根据所述图像集合的采集位置及图像的分布密度将所述图像集合划分为至少一个子集合，若某区域采集位置的图像数量较多，即图像密度较大，则 多划分几个子集合，相应地，图像密度较小的区域则少划分几个子集合。所述子集合的选择条件可以为保证子集合中需要包括媒体对象。这里的子集合的数量以及子集合的形状、面积可以根据实际情况设定，本发明对此不进行限定。
步骤503：在仅获取到稳定性参数时，在每个子集合中选取采集稳定性参数最大的图像作为显示对象。
步骤504：在获取到稳定性参数以及兴趣点参数时，在每个子集合中选取由稳定性参数以及兴趣点参数加权求和最大的图像作为显示对象。
步骤503与步骤504之间是“或者”的关系，即这两个步骤是从每个区间内选取显示对象的两种不同的实施方式。可以根据实际应该情况灵活选择仅获取稳定性参数，或获取稳定性参数以及兴趣点参数，可以理解的是，仅获取稳定性参数计算量小，而采用稳定性参数以及兴趣点两个参数共同参与显示对象的选择，选取的显示对象更贴近用户需求。
稳定性参数与兴趣点参数的确定可以参见上述实施例，则在选取媒体对象时可以选取每个区间内稳定性参数最大的图像作为显示对象，也可以将各个图像的稳定性参数与兴趣点参数加权求和，综合两个不同的指标，在每个区间内选取加权求和最大的图像作为显示对象。
步骤505：调用地图数据，根据显示对象的采集位置，将显示对象显示在地图上，使显示对象在地图上的显示位置与显示对象的采集位置一致，或使显示对象在地图上的显示位置与显示对象的采集位置之间的距离在预设范围之内。
本步骤与步骤103类似，在此不再赘述。
参见图6所示，是本发明实施例中提供的实现媒体对象显示的方法实施例四，当媒体对象为视频时，可以包括以下步骤：
步骤601：获取采集得到的视频。
步骤602：在仅获取到稳定性参数时，根据稳定性参数，在所述视频中每隔预设时间截取一段视频片段或一个视频帧作为显示对象。即每个预 设时间，选取一段稳定性参数最大的视频片段或一个稳定性参数最大的视频帧。
步骤603：在获取到稳定性参数以及兴趣点参数时，根据稳定性参数和兴趣点参数，在所述视频中每隔预设时间截取一段视频片段或一个视频帧作为显示对象。即每个预设时间，选取一段稳定性参数和兴趣点参数加权求和最大的视频片段或一个稳定性参数和兴趣点参数加权求和最大的视频帧。
对于视频来说，需要从视频中选取关键的视频片段或视频帧作为显示对象，可以每隔预设时间段，截取预设时间段中的一小段视频，或截取一个视频帧，预设时间可以根据实际情况设定。
步骤602与步骤603之间是“或者”的关系，即这两个步骤是从每段视频片段中选取显示对象的两种不同的实施方式。可以根据实际应该情况灵活选择仅获取稳定性参数，或获取稳定性参数以及兴趣点参数，可以理解的是，仅获取稳定性参数计算量小，而采用稳定性参数以及兴趣点两个参数共同参与显示对象的选择，选取的显示对象更贴近用户需求。
稳定性参数与兴趣点参数的确定可以参见上述实施例，则在选取媒体对象时可以选取每段视频片段中稳定性参数最大的视频帧作为显示对象，也可以将各个视频帧的稳定性参数与兴趣点参数加权求和，综合两个不同的指标，在每段视频片段中选取加权求和最大的视频帧作为显示对象。
步骤604：调用地图数据，根据显示对象的采集位置，将显示对象显示在地图上，使显示对象在地图上的显示位置与显示对象的采集位置一致，或使显示对象在地图上的显示位置与显示对象的采集位置之间的距离在预设范围之内。
本步骤与步骤103类似，在此不再赘述。
另外，在本发明的一些实施例中，还可以接收并保存用户输入的采集轨迹信息和/或媒体对象对应的采集位置。
即用户可以根据自己的喜好，更改媒体对象的采集位置和/或采集轨迹， 并永久保存，下次再打开客户端的时候可以按照用户更改的采集位置信息以及采集轨迹呈现媒体对象，例如用户可以改成心形的采集轨迹，以表达自己的爱意，使媒体对象显示更为灵活多样。
在本发明的一些实施例中，还可以将媒体对象以及对应的采集位置上传到服务器；在用户点击地图上任一点时，从服务器获取采集位置及该位置信息所对应的媒体对象进行显示或播放。
用户还可以选择将自己所喜爱的图媒体对象上传到云端服务器，和其他用户分享，也可以看到其他用户上传的媒体对象，达到一种促进交流的作用。
这样，本发明实施例通过获取媒体对象以及对应的采集位置以及采集姿态信息，对采集位置以及采集姿态信息进行分析，筛选出采集位置有一定间隔，且采集姿态比较稳定的图像或视频帧作为精选并在地图相应位置上显示，使用户在查看媒体对象时，可以直观看到媒体对象与地理位置的关系，显示直观，且通过显示对象的索引可以更快确定查找内容的位置，极大了方便了用户查阅。
相应的，参见图7所示，是本发明实施例中提供的实现媒体对象显示的装置实施例一，可以包括：
所述实现媒体对象显示的装置包括获取模块701、确定模块702及第一显示模块703。
获取模块701，可以用于获取采集得到的媒体对象。
在获取采集到的媒体对象的同时，还可以一并获取媒体对象对应的采集位置以及采集姿态信息。在使用媒体对象采集设备采集媒体对象的过程中，例如使用无人机航拍图片和/或视频的过程中，可以记录下媒体对象的采集位置，采集位置可以使用GPS信息进行标识，同时可以记录下媒体对象的采集姿态信息，采集姿态信息可以为惯性测量单元数据，惯性测量单元数据可以包括采集媒体对象时，采集设备三轴的姿态角，或角速率，以及加速度，用于代表媒体对象的采集姿态。进一步的，采集姿态信息还可以包括采集朝向、采集高度等信息。可以理解的是，当媒体对象为图像集 合时，每一幅图像均可以有对应的采集位置与采集姿态信息；当媒体对象为视频时，则视频中每一视频帧均及每一视频片段中的视频帧可以有对应的采集位置与采集姿态信息。
在本发明的一些实施例中，采集媒体对象的过程中，还可以记录采集轨迹信息，采集轨迹信息是指媒体对象采集设备的运动轨迹即采集轨迹，可以理解每个媒体对象的采集位置均分布在采集轨迹上。
当用户需要使用装载在显示终端的客户端浏览媒体对象时，获取模块可以首先获取采集得到的媒体对象以及媒体对象对应的采集位置和采集姿态信息。

具体的，即当媒体对象为图像集合时，如果每个子集合图像数量较少，且各幅图像采集地点比较分散，即图像数量小于或等于数量阈值，且各个图像之间的采集位置距离差值大于或等于距离阈值，则可以直接选择全部图像进行显示，否则，则需要将子集合中满足预设条件的图像确定为显示对象。其中，数量阈值以及距离阈值可以根据实际情况进行设定，本发明对此不进行限定。
第二选取单元7022，可以用于若所述图像集合的子集合中所述图像的数量大于数量阈值，将子集合中满足预设条件的图像确定为显示对象，或在所述媒体对象为视频时，从所述视频中选取满足预设条件的媒体片段作 为显示对象并获取所述显示对象所对应的采集位置信息。从所述视频中选取的媒体片段可以为视频片段或视频帧。

具体的，当媒体对象为图像集合时，若所述图像集合的每一子集合上图像数目大于数量阈值，选取稳定性参数最大的图像或稳定性参数和兴趣点参数加权求和最大的图像作为显示对象。当媒体对象为视频时，即可以在所述视频中每隔预设时间截取一段视频片段或在所述视频中每隔预设时间确定出一个视频帧作为显示对象，所述显示对象为所述预设时间内稳定性参数最大的媒体对象或稳定性参数和兴趣点参数加权求和最大的媒体对象。
这样，可以从大量媒体对象中，选取分散且图像质量更好的图像或视频帧进行显示。
第一显示模块703，可以用于调用地图数据，根据显示对象的采集位置，将显示对象显示在地图上。
显示对象是从媒体对象中选取获得的，即显示对象有对应的采集位置，进一步的，本发明实施例根据显示对象的采集位置在地图的相应位置进行显示，显示对象在地图上的显示位置与显示对象的采集位置一致，或使显示对象在地图上的显示位置与显示对象的采集位置之间的距离在预设范围之内，使用户可以直观获得媒体对象的采集位置或采集位置的范围。
在本发明的一些实施例中，还可以包括第二显示模块，用于获取采集轨迹信息，调用地图数据，根据采集轨迹信息在地图上显示采集轨迹。第三显示模块，用于在接收用户通过点击显示对象而输入的显示触发信号后，显示或播放显示对象以及在距显示对象的预设范围内的其他媒体对象。

稳定性参数可以根据媒体对象对应的采集姿态信息中包括的惯性测量单元数据确定，在同等清晰度条件下采集稳定性高代表采集到的媒体对象质量更好。兴趣点参数可以代表媒体对象的内容中包括用户兴趣点信息的可能。这样，在选取媒体对象时可以选取每个子集合内稳定性参数最大的 图像作为显示对象，也可以将各个图像的稳定性参数与兴趣点参数加权求和，综合两个不同的指标，在每个子集合内选取加权求和最大的图像作为显示对象。
