具体实施方式
下面结合附图和实施例对本申请作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释相关发明，而非对该发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与有关发明相关的部分。
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
图1示出了根据本申请的用于在全景视频中融合对象的方法的一个实施例的流程200。本实施例的用于在全景视频中融合对象的方法，包括以下步骤：
步骤101，在全景视频播放器中播放全景视频。
在本实施例中，用于在全景视频中融合对象的方法运行于其上的电子设备(例如终端设备)上可以播放全景视频。具体的，上述终端设备上可以安装有用于播放全景视频的应用，如各种全景视频播放器。
在本实施例的一些可选的实现方式中，上述步骤101可以通过图1中未示出的以下步骤来实现：
获取全景视频的序列帧；将各序列帧映射在预设的全景视频播放模型的内表面；将全景视频播放模型的对应观察界面的部分投影到投影面，以播放全景视频。
全景视频的每帧是一张360度全景图像，全景视频包括多张360度全景图像。将各序列帧映射在预设的全景视频播放模型的内表面，上述全景视频播放模型可以是根据全景视频的特点认为建立的模型，其是一种虚拟模型，比如可以是球体模型、立方体模型、棱锥模型等。以球体模型为例，其包括以球心为中心的360度全空间，将上述全景图像投影在球体模型的内表面，相当于人眼在球心位置观测全景图像。然后将全景视频播放模型对应的观察界面的部分投影到投影面，以播放全景视频。以观察者的眼睛为全景视频播放模型的中心，利用透视投影的规则，该全景视频播放模型的表面中位于投影区域内的表面上映射的全景图像会投影到成像投影面上，该投影面上的视频/图像最终显示到全景视频播放器的屏幕上。
步骤102，获取目标对象。
本实施例中，目标对象可以是各种待融合入全景视频中的对象，例如动画表情，文字符号或各种用于推广的物品等等。目标对象的格式可以是各种可以融合到全景视频中的格式，例如可以是obj格式。上述终端设备可以通过各种有线或无线连接的方式获取目标对象，例如，终端设备可以获取本地存储的目标对象，也可以获取用户通过各种方式输入的目标设备。
需要指出的是，上述无线连接方式可以包括但不限于3G/4G连接、WiFi连接、蓝牙连接、WiMAX连接、Zigbee连接、UWB(ultra wideband)连接、以及其他现在已知或将来开发的无线连接方式。
步骤103，解析目标对象，得到目标对象的坐标参数以及材质参数。
在获取到上述目标对象后，终端设备可以对上述目标对象进行解析，确定目标对象的坐标参数以及材质参数。上述坐标参数可以包括目标对象的顶点坐标、每个顶点的法线坐标等，上述材质参数可以包括目标对象各个面的参数以及每个面的材质的参数。
步骤104，根据坐标参数以及材质参数，设置目标对象融合在全景视频时每个像素的颜色，得到着色后的目标对象。
终端设备在确定了目标对象的坐标参数以及材质参数后，可以为目标对象着色，即设置目标对象在融合在全景视频时每个像素的颜色，得到着色后的目标对象。
步骤105，将着色后的目标对象融合在全景视频中。
在为目标对象着色后，可以将着色后的目标对象融合在全景视频中，则实现了在播放全景视频时融合其它对象。
继续参见图2，图2是根据本实施例的用于在全景视频中融合对象的方法的应用场景的一个示意图。在图2的应用场景中，全景视频播放器中播放全景视频21，在播放过程中，获取目标对象，经解析后并设置目标对象21的颜色，得到着色后的目标对象，然后将着色后的目标对象22融合在全景视频21中。
本申请的上述实施例提供的用于在全景视频中融合对象的方法，在全景视频播放器中播放全景视频时，获取目标对象，然后对获取的目标对象进行解析，得到目标对象的坐标参数以及材质参数，然后根据上述坐标参数和材质参数，设置目标对象融合在全景视频时每个像素的颜色，得到着色后的目标对象，最后将着色后的目标对象融合在全景视频中。本实施例的方法，不仅能够播放全景视频的内容，还可以在播放的全景视频中很好的融合目标对象，增加了全景视频的特效性。
在本实施例的一些可选的实现方式中，上述步骤105具体可以通过图1中未示出的以下步骤来实现：获取目标对象在全景视频中的位置坐标；对着色后的目标对象进行处理，上述处理包括以下至少一项：缩放、平移、旋转；根据上述位置坐标，定位处理后的目标对象。
本实现方式中，终端设备可以首先获取目标对象在全景视频中的位置坐标，然后对着色后的目标对象进行处理，例如缩放、平移或旋转，然后将处理后的目标对象定位在上述位置坐标处。这样，可以使得观察者可以从任意角度观察目标对象。
在本实施例的一些可选的实现方式中，上述方法还可以包括图1 中未示出的以下步骤：
获取所述全景视频播放器的传感器数据；根据所述传感器数据，确定全景视频播放器的朝向是否与所述位置坐标相交；响应于所述全景视频播放器的朝向与所述位置坐标相交，统计二者相交的持续时间；当所述持续时间大于预设阈值时，显示预设的交互界面
本实现方式中，可以根据全景视频播放器的传感器数据，确定全景视频播放器的朝向。然后判断上述朝向是否与目标对象的位置坐标相交，如果相交，则统计全景视频播放器的朝向与目标对象的位置坐标相交的持续时间，当上述持续时间大于预设阈值时，显示预设的交互界面。当目标对象为待推广的物品时，上述交互界面可以包括物品的信息、删除目标对象按钮或将目标对象加入购物车等按钮，以实现观察者与目标对象的交互。本实现方式中，全景视频播放器的朝向可以理解为观察者的眼睛所观察的方向，也就是说，观察者可以通过本实现方式通过长盯来实现与目标对象的交互。
继续参见图3，其示出了根据本申请的用于在全景视频中融合对象的方法中为目标对象着色的一个实施例的流程300。如图3所示，本实施例中可以通过以下步骤实现为目标对象着色：
步骤301，根据坐标参数，确定所述目标对象投影到投影面对应的二维坐标。
本实施例中，根据目标对象的坐标参数(例如顶点坐标以及法线坐标)可以确定目标对象投影到投影面上其所覆盖的部分对应的二维坐标。可以理解的是，上述二维坐标可以包括多个坐标，上述多个坐标用于表示目标对象在投影面上覆盖的部分。
步骤302，根据上述材质参数，确定目标对象对光线的反射系数。
物体对光线的反射包括镜面反射和漫反射，镜面反射的系数要大于漫反射的反射系数。漫反射通常是光线照射在粗糙的物体表面发生，且不同的材质在发生漫反射时的反射系数也不同。本实施例中，终端设备可以根据上述材质参数，确定目标对象对光线的反射系数。
在本实施例的一些可选的实现方式中，终端设备可以根据预设的材质参数与反射系数的对应列表以及上述目标对象的材质参数，确定 目标对象对光线的反射系数。
本实现方式中，终端设备可以首先获取包含材质参数与反射系数的对应关系的列表，然后根据该列表以及目标对象的材质参数，确定目标对象对光线的反射系数。
步骤303，根据上述二维坐标、上述反射系数以及预设的环境光强度和方向光强度，确定在全景视频中融合目标对象时各像素的颜色。
在确定了目标对象在投影面上的二维坐标以及目标对象对光线的反射系数后，可以根据预设的环境光强度和方向光强度，确定在全景视频中融合目标对象时各像素的颜色。环境光是指目标对象所处的环境中的光线，方向光是指来自某一方向的平行光。由于环境光的强度和方向光的强度为预设的，所以可以确定在全景视频中融合目标对象时各像素的颜色。
在本实施例的一些可选的实现方式中，上述步骤303可以通过图3中未示出的以下步骤来实现：根据上述二维坐标，确定目标对象融合在全景视频时各像素的坐标；根据各像素的坐标、上述反射系数以及预设的环境光强度和方向光强度，确定目标对象融合在全景视频时各像素的光照强度；根据各像素的光照强度，确定各像素的颜色。
本实现方式中，可以根据上述二维坐标，确定目标对象融合在全景视频中各像素的坐标，然后根据各像素的坐标、上述反射系数以及预设的环境光强度和方向光强度，确定环境光和方向光在各像素的光照强度，最后根据各像素的光照强度，确定各像素的颜色。
本申请的上述实施例提供的用于在全景视频中融合对象的方法，可以为目标对象着色，使得融合目标对象后的全景视频不突兀，提升观察者的观看体验。
进一步参考图4，作为对上述各图所示方法的实现，本申请提供了一种用于在全景视频中融合对象的装置的一个实施例，该装置实施例与图1所示的方法实施例相对应，该装置具体可以应用于各种电子设备中。
