Description

一种物品图像的展示方法、装置及系统
本申请要求2016年04月06日递交的申请号为201610211628.5、发明名称为“一种物品图像的展示方法、装置及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及图像处理技术领域，具体涉及一种物品图像的展示方法及装置。本申请同时涉及一种视频下发方法及装置，一种物品图像的展示系统，一种电子设备，以及一种视频数据生成方法、装置及电子设备。
背景技术
随着互联网技术的高速发展，通过电子商务网站进行商品交易已成为日益普及的一种方式。为了提高商品购买率、降低退货数量，电子商务网站需要给用户提供尽可能充分的商品信息，这些信息可以通过文字、图片和用户评论等形式提供。
在电子商务发展的早期阶段，电商平台主要通过平面图片的单一展示方式向消费者展示商品。随着用户爆发式的增长，平面图片的单一展示方式已经无法满足用户的需求。为了提高用户体验，电子商务网站需要对商品进行多方位展示。
目前，电子商务网站提供商品多方位展示的方法包括：1)选取商品多角度的多张图片，将这些图片以轮播或拼图形式展现；2)直接播放为商品录制的视频；3)采用专门的全局SDK(Software Development Kit，软件开发工具包)来展示全景效果。
然而，上述现有商品多方位展示方法均存在一些问题。上述方法1需要将多个图片进行拼接，因而存在播放画面失真的问题，从而降低了用户体验。上述方法2需要请求整个视频资源，因而存在消耗较高流量和电量的问题，特别的，如果网络不好则无法很好的将商品呈现给用户。同时，采用上述方法1或方法2的观看效果均为用户的被动观看，即：用户无法方便地主动选取商品特定角度图像进行观看，因而，无法带给用户立体直观的感受，既没有3D空间感，画面也不够真实。上述方法3通过SDK安装包能够带给用户立体直观的感受，具有3D空间感及真实感，增强了商品的展示效果。然而，方法3所应用的SDK安装包通常较大，因而存在消耗较高流量和电量的问题。
综上所述，现有技术存在无法兼顾较低资源消耗及较高用户体验两方面优势的问。

本申请提供的物品图像的展示方法，用于配置有运动检测装置的移动智能设备。所述的移动智能设备，即：通常所说的手机或者智能手机、平板电脑、可穿戴设备等。所述的运动检测装置安装在移动智能设备中，能够实时检测获得移动智能设备的倾斜角参数。通过运动检测装置提供的库函数，移动智能设备能够实时采集到运动检测装置检测获得的移动智能设备的倾斜角参数。
应用本申请提供的物品图像的展示方法控制物品图像展示的一个关键之处是：对移动智能设备位置、姿态的确定和推算。本步骤在测得移动智能设备的倾斜角参数后，通过运动检测装置提供的库函数，即可完成对移动智能设备位置、姿态的确定和推算处理，进而得到移动智能设备的方位角，即：倾斜角度以及倾斜方向。
所述的运动检测装置不限于角速度传感器，还可以是重力感应器(G-sensor)、或其它能够获取移动智能设备倾斜角参数的传感器。下面对各种形式的运动检测装置作简要说明。
1)重力感应器。
通过重力感应器可以检测得到重力方向。在具体实施时，可采用多轴的重力感应器以检测移动智能设备切向于竖直方向的转动，从而确定移动智能设备的翻转角度，即：移动智能设备的倾斜角度以及倾斜方向。
2)角速度传感器。
角速度传感器是一种能够测量设备偏转与倾斜角度的硬件。角速度传感器应用Coriolis力原理，主要应用于汽车导航、运动物体的位置控制和姿态控制、以及其它需要精确角度测量的场合。
不同于重力感应器的是，角速度传感器的测量物理量是偏转、倾斜时的转动角速度。角速度是指单位时间内位移的增量。角速度传感器和重力感应器最大的区别就是重力传感器对于空间上的位移感受维较少，能做到6个方向的感应就已经很不错了，而角速度 传感器则是全方位的。
常见的角速度传感器包括陀螺仪等。以陀螺仪为例，该装置可以对转动、偏转的动作做很好的测量，进而可以精确分析判断出使用者的实际动作。而后根据动作可对移动智能设备做相应的操作。在移动智能设备上，通过陀螺仪可测量、重构出完整的3D动作。陀螺仪完整监测用户手的位移，从而实现各种观看角度的操作效果。
在本实施例中，移动智能设备为iPhone智能手机，该手机内置微机电陀螺仪(MEMS)。通过陀螺仪测得移动智能设备的瞬时角速度(A/D转换值)，通过程序采集到移动智能设备在不同转速下的陀螺仪角速度后，进行对时间的数字积分，进而可得到移动智能设备的方位角，从而确定移动智能设备的倾斜角度以及倾斜方向。通常，在每个转速下都采集7组数据，每组数据大约200个值。
在本实施例中，采用角速度传感器作为运动检测装置，角速度传感器检测获得的倾斜角参数包括角速度、时间、位移等参数。
需要注意的是，在实际使用过程中，突出的问题是噪声对陀螺仪输出有很大的影响，给后续控制移动智能设备带来很大的障碍。当前处理噪声的方法主要有硬件除噪和软件除噪。硬件除噪要考虑电路的可靠性、稳定性，且要追加成本。软件除噪则较为灵活，成本较低，被广泛采用。
3)角速度传感器与重力感应器的结合。
作为一种优选的实施方式，还可结合角速度传感器和重力感应器作为运动检测装置。短时间用角速度传感器找到相对于重力方向的角度，长时间用重力感应器去修整角速度传感器测到的角度，从而提高确定的移动智能设备的倾斜角度以及倾斜方向的准确性。
以上对可应用的三种运动检测装置进行了简要说明。上述三种运动检测装置均具有各自的优缺点。其中，重力感应器的成本最低，以手机为例，目前绝大多数手机都配置了重力感应器。然而，重力感应器是测量加速度的传感器，各种震动均会影响加速度计的测量结果，从而不能得到准确重力方向，进而得到的角度值的准确性也较低。相对于重力传感器而言，通过角速度传感器确定移动智能设备的倾斜角度、倾斜方向的准确性显著提高。然而，角速度传感器的成本则较高，以陀螺仪为例，现在使用陀螺仪的手机机型比较少，包括：iPhone系列手机、三星盖世系列手机、谷歌手机、小米2等。将角速度传感器与重力感应器组合作为运动检测装置的实施方式，能够进一步提高测量的角度的准确性。但是，该方式的成本最高。在实际应用中，可根据具体情况选用适当的运 动检测装置。
步骤S103：根据所述倾斜角度和所述倾斜方向，从待展示物品的视频中提取与所述移动智能设备的当前姿势对应的一帧物品图像。
本步骤是实现待展示物品图像切换的关键步骤，在确定移动智能设备的倾斜角度以及倾斜方向后，从待展示物品的视频中提取与移动智能设备的当前姿势对应的一帧物品图像。
在具体实施时，可采用如下步骤从待展示物品的视频中提取与所述移动智能设备的当前姿势对应的一帧物品图像。
1)根据所述移动智能设备的倾斜角度以及倾斜方向，确定所述待展示物品的待展示角度。
所述的待展示物品的视频包括该物品在不同展示角度(即：不同拍摄角度)对应的每一帧图像。为了能够根据移动智能设备的姿态变化对待展示物品的图像进行切换，首先需要根据移动智能设备的姿态，确定待展示物品的待展示角度。
在具体实施时，可采用如下步骤确定待展示物品的待展示角度。首先，需要获取为待展示物品预设的首次显示图像的展示角度。所述的首次显示图像是指，用户提出对应待展示物品的观看请求后，该物品的第一张显示图像。通常，可将待展示物品的最佳展示角度、最能表示物品特征的图像指定为所述的首次显示图像。在实际应用中，还可将首次显示图像的展示角度默认为0度，即：首次显示图像为待展示物品视频的第一帧图像。
在步骤S101确定移动智能设备的倾斜角度以及倾斜方向后，可根据预设的首次显示图像的展示角度，计算待展示物品的待展示角度。例如，待展示物品的视频包括围绕该物品转120度所拍摄的图像，即：第1帧图像对应0度，最后一帧图像对应120度，首次显示图像的展示角度设置为50度；在首次显示50度拍摄角度对应的物品图像后，如果将手机向右转动5度角，则待展示角度变换为55度，将显示55度拍摄角度对应的物品图像；如果将手机向左转动5度角，则待展示角度变换为45度，将显示45度拍摄角度对应的物品图像。
2)根据所述视频的图像帧序号和图像拍摄角度之间的对应关系，获取所述待展示物品在所述待展示角度所呈现图像的帧序号。
通过上一步骤确定待展示物品的待展示角度后，可根据待展示物品视频的图像帧序 号和图像拍摄角度之间的对应关系，获取待展示物品在待展示角度所呈现图像的帧序号。由此可见，所述的待展示物品的视频不同于一般的物品视频。一般的物品视频仅包括视频文件本身，而本申请所述的待展示物品的视频还包括视频文件中的各个图像的帧序号和拍摄角度之间的对应关系，即所述视频的图像帧序号和图像拍摄角度之间的对应关系。
要生成本申请所述的待展示物品的视频，可采用多种方式进行拍摄，简单便捷的方式为使用具有运动检测装置及拍摄装置的移动智能设备进行拍摄，例如，内置陀螺仪及拍摄装置的智能手机等。当拍摄者手持移动智能设备围绕待展示物品进行拍摄时，对于拍摄到的待展示物品的各个展示角度所呈现图像，通过运动检测装置实时确定各个展示角度所呈现图像对应的拍摄角度；根据各个展示角度所呈现图像的帧序号和各个展示角度所呈现图像的拍摄角度，形成图像帧序号和图像拍摄角度之间的对应关系。
请参看图2，其为本申请的物品图像的展示方法的实施例的不同拍摄角度呈现图像的示意图。由图2可见，围绕被拍摄物体转动一圈(360度)进行拍摄，假设拍摄的起始角度(对应初始机位)为0度(对应图a))，拍摄的终止角度(对应结束机位)为150度(对应图b))，拍摄结束后即可抓取到各个图像帧与其拍摄角度的对应关系。
在实际应用中，还可采用其它方式对待展示物体进行拍摄，只要能够获取图像帧序号和图像拍摄角度之间的对应关系即可。下面给出其它几种适用于不同场景的物体拍摄方法。
拍摄方法一、被拍摄物品固定不动，配置圆形轨道，将相机架设在轨道上，让相机以一个固定的角速度围绕物体进行拍摄。这里的角速度为预设值，也就是说拍摄角度和图像帧序号的对应关系已知，如转角x则对应图像A。这种拍摄方式适用于大型物体的拍摄，比如轿车等；但需要投入较大的资金，大商家可以用到，小商户则不利于推广。
拍摄方法二、给被拍摄物品(比如小玩具)配置一个电机地盘，以恒定角速度做圆周运动，相机固定拍摄，也可以得到全景视频。这里的角速度也是预设的，即拍摄角度和图像帧序号的对应关系已知。这种拍摄方式适用于小型物体的拍摄，比如小玩具等；仍需要部分资金的投入，如购买摄像设备，购买摄影棚和电机等等。
综上所述，直接使用移动智能设备对待展示物体进行拍摄是一种较为快捷简单的方法。
3)根据获取到的所述帧序号，从所述视频中提取所述物品图像。
根据移动智能设备的当前姿态确定待展示图像的帧序号后，即可根据获取到的帧序 号，从待展示物品的视频中提取与当前姿势对应的一帧物品图像。
在具体实施时，可在用户提出针对待展示物品的观看请求时，从视频存储设备(如服务器)中下载视频文件。随着用户手势的变化，当需要对待展示物品进行图像切换时，直接从已下载的视频文件中即可提取到与当前姿势对应的一帧物品图像。
然而，在实际应用中，用户可能并不需要观看物品的所有已拍摄图像(各个展示角度对应的图像)，而可能仅需观看部分角度的图像。在这种情况下，上述一次性下载完整视频文件的方式显然存在浪费网络流量的问题。为了降低网络流量消耗，可在物品图像展示过程中，根据一定视频下载规则向服务器请求下载仅包括待展示图像及其前后相邻图像的视频片段。
所述的视频片段包括在待展示角度所呈现图像、及在待展示角度所呈现图像之前相邻图像和之后相邻图像。例如，视频片段包括小于待展示角度10度内的相邻图像、待展示角度所呈现图像、及大于待展示角度10度内的相邻图像；或者，视频片段包括待展示角度所呈现图像之前相邻20帧图像至待展示角度所呈现图像之后相邻20帧图像之间的所有图像。
在具体实施时，获取所述视频片段的过程为：首先，向服务器发送对应待展示物品在待展示角度所呈现图像的视频片段请求，该视频片段请求携带有待展示物品在待展示角度所呈现图像的标识信息；服务器接收到客户端发送的对应待展示物品的视频请求后，根据视频片段请求携带的待展示物品在待展示角度所呈现图像的标识信息，从预先存储的待展示物品的视频中提取视频片段，并向客户端回送提取到的视频片段；客户端接收到服务器回送的视频片段后，即可从视频片段中提取物品图像。其中，所述的标识信息包括待展示角度或在待展示角度所呈现图像的帧序号。
由于视频片段包括待展示角度所呈现图像、及其之前若干帧图像和之后若干帧图像，因此，如果已下载的视频片段中包括待展示物品在待展示角度所呈现图像，则在显示该图像时无需再向服务器请求下载包括待展示角度所呈现图像的视频片段，直接从已下载的视频片段提取待展示角度所呈现图像即可。
步骤S105：将提取到的物品图像显示在与所述移动智能设备有关联关系的屏幕上。
所述的与移动智能设备有关联关系的屏幕包括但不限于：移动智能设备的显示器，还可以为与移动智能设备相连接的其他显示设备，例如，投影仪等，通过投影仪可将提取到的物品图像显示在大屏幕上，从而增强用户的视觉感受。
在具体实施时，可采用OpenGL技术对提取到的物品图像进行图像渲染。OpenGL可使用硬件设备提高图像处理的速度，具有提高渲染速度、突破Java内存限制、便于加入更多渲染特效的优点，从而能够提高物品图像展示的整体性能，提供给用户流畅的立体观感。
