云交互系统中大部是基于视频流，也就是说服务器把图像渲染出来，然后压缩后传输到用户设备，这个过程需要很大的带宽，并需要大量服务器资源，如果用户设备断线，还需要重新上线发送完整视频流，这个过程也需要大量服务器存储资源进行视频流的保存，技术实现困难。

为了使本技术领域的人员更好地理解本申请的方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
如图1所示，为本发明实施例中提供的云交互式系统的示意图，所述云交互式系统包括用户设备和服务器，其中，服务器和用户设备通过网络进行数据交互，例如，服务器将录制的图像帧的绘制数据通过网络发送到用户设备，其中，绘制数据可以是绘制指令或绘制资源，绘制指令可以被用户设备使用执行相应的绘制资源，得到相应图像帧绘制后的图像，服务器、用户设备可以是下面实施例描述的任一种可能的服务器、用户设备。
下面首先介绍本发明实施例中图像绘制的方法，所述方法可以应用于所述云交互式系统。
请参阅图2，本发明实施例中图像绘制的方法一个实施例包括：
201、服务器在与所述用户设备的中断连接恢复后，确定所述用户设备是否保存有第一绘制资源。
可选的是，在步骤201之前，本发明实施例的图像绘制方法还包括服务器在向所述用户设备传输绘制资源时判断与所述用户设备之间的连接是否发 生中断，发生中断后，服务器确定与用户设备的中断连接是否已恢复。
在传输绘制资源时发生连接中断的图像帧也称作中断图像帧，该图像帧可以包括或对应于包括第一绘制资源在内的多个绘制资源。
在云交互式系统中，经常会有一些突发的状况导致服务器和用户设备中断连接，例如网络不稳定等，此时，在服务器中可以设置一资源缓存，用于保存服务器向用户设备发送的绘制资源，在服务器和用户设备中断连接恢复后，可以将资源缓存中的绘制资源同步到用户设备，以保证服务器和用户设备之间的绘制资源同步，在资源缓存中，同时可以将服务器发送的绘制指令保存在资源缓存中。
本发明实施例中，所述确定所述用户设备中中断图像帧未保存的第一绘制资源，有多种实现方式，下面分别进行说明。
(1)用户设备确定第一绘制资源并告知服务器；
具体的，所述确定所述用户设备中中断图像帧未保存的第一绘制资源，可以包括：
所述服务器向所述用户设备发送第一哈希值，所述第一哈希值用于所述用户设备确定所述用户设备中是否保存有所述第一绘制资源，例如所述第一哈希值与所述第一绘制资源对应；
所述服务器接收所述用户设备发送的资源缺失响应，所述资源缺失响应用于指示所述服务器在所述用户设备中未保存所述第一绘制资源。
(2)服务器确定第一绘制资源
具体的，所述确定所述用户设备中中断图像帧未保存的第一绘制资源，可以包括：
所述服务器接收所述用户设备发送的第二哈希值，所述第二哈希值用于指示所述服务器所述第二哈希值对应的第二绘制资源在所述用户设备中已保存；
所述服务器根据所述第二哈希值，确定所述用户设备中未保存的所述第一绘制资源。
其中，服务器根据第二哈希值，确定所述用户设备中未保存的所述第一绘制资源，具体可以是：服务器根据自身已保存的所有绘制资源，分别生成 对应的哈希值，在所生成的哈希值中有与所述第二哈希值不同的哈希值时，确定该不同的哈希值对应的绘制资源为所述用户设备中未保存的绘制资源，即所述用户设备中未保存的所述第一绘制资源。
或者，服务器根据第二哈希值，确定所述用户设备中未保存的所述第一绘制资源，可以是：服务器判断所述第二哈希值是否与第一哈希值相等(其中所述第一绘制资源与第一哈希值对应)；所述服务器根据所述判断结果，确定所述用户设备是否保存有所述第一绘制资源。
本实施例中，哈希值可以是消息摘要算法第五版(Message Digest Algorithm MD5，MD5)、MD4等类型的哈希值，需要说明的是，在同一个技术方案中，涉及哈希值比对判断的过程，可以理解为同一类型的哈希值比对判断。
202、服务器向所述用户设备发送所述第一绘制资源；
在所述用户设备未保存所述第一绘制资源的情况下，所述服务器向所述用户设备发送所述第一绘制资源。
其中，所述第一绘制资源传输到所述用户设备后被所述用户设备缓存，用户设备通过接收服务器发送到的第一绘制资源，实现用户设备和服务器中绘制资源的同步。
在实际发送第一绘制资源的过程中，第一绘制资源的数据大小可能较大，此时，为了避免流量过大，可以先发低精度资源显示画面，再发高精度资源慢慢替换低精度资源的显示，例如可以先发第一绘制资源的压缩数据，再发第一绘制资源。
因此，此处所述服务器向所述用户设备发送所述第一绘制资源，可以包括：
所述服务器向所述用户设备发送第一资源，所述第一资源由所述第一绘制资源压缩后得到；
所述服务器向所述用户设备发送第二资源；
其中，所述第二资源由所述第一绘制资源压缩后得到，所述第一资源的数据精度低于所述第二资源的数据精度，或者所述第二资源为所述第一绘制资源。
203、服务器向所述用户设备发送绘制指令。
所述绘制指令被所述用户设备使用与所述绘制指令对应的绘制资源(例如所述第一绘制资源)执行，得到所述中断图像帧绘制后的图像。
而本发明实施例中在服务器在与所述用户设备的中断连接恢复后，将用户设备中中断图像帧未保存的绘制资源发送到用户设备，使得用户设备和服务器实现资源的同步，同时发送相应的绘制指令，实现图像的显示，由于服务器和用户设备中断连接恢复后，服务器并不需要向用户设备发送全部的绘制数据，节省了网络带宽，提高了传输效率且降低了实现难度。
下面介绍用户设备侧图像绘制的方法的实施例，所述方法应用于云交互式系统，所述云交互式系统包括用户设备和服务器。
请参阅图3，本发明实施例中图像绘制的方法的另一个实施例包括：
301、用户设备在与所述服务器的中断连接恢复后，接收所述服务器发送的第一绘制资源。
用户设备在接收到第一绘制资源后可以缓存所述第一绘制资源。
其中，在传输绘制资源时发生连接中断的图像帧称作中断图像帧，该图像帧可以包括或对应于包括第一绘制资源在内的多个绘制资源。所述第一绘制资源为所述用户设备中未保存的绘制资源，服务器发送给用户设备进行缓存，以备后续从服务器接收到相应的绘制指令后，使用该绘制资源执行相应的绘制指令，得到图像帧的图像。
可选的是，在步骤301之前，本发明实施例的图像绘制方法还包括用户设备确定与服务器的中断连接是否已恢复。
302、用户设备接收所述服务器发送的绘制指令。
用户设备接收所述服务器发送的绘制指令后可以调用所述绘制指令对应的绘制资源；
所述绘制指令对应的绘制资源可以是中断的图像帧包括或对应的所有绘制资源，或者这些绘制资源中的一部分。可选的，所述绘制指令对应的绘制资源至少包括所述第一绘制资源。
303、用户设备使用所述绘制指令对应的绘制资源执行所述绘制指令，得到所述中断图像帧绘制后的图像。
在所述第一绘制资源为所述用户设备中未保存的绘制资源时，所述接收所述服务器发送的中断图像帧的第一绘制资源之前，所述方法还可以包括确认第一绘制资源的过程，此过程具体实现方式有多种，下面分别进行介绍：
(1)，所述接收所述服务器发送的中断图像帧的第一绘制资源之前，所述方法还包括：
所述用户设备接收所述服务器发送的第一哈希值；
所述用户设备根据所述第一哈希值确定所述用户设备中是否保存有所述第一绘制资源；
所述用户设备确定未保存有所述第一绘制资源时，向所述服务器发送资源缺失响应，所述资源缺失响应用于指示所述服务器在所述用户设备中未保存所述第一绘制资源。
(2)所述接收所述服务器发送的中断图像帧的第一绘制资源之前，所述方法还包括：
所述用户设备向所述服务器发送第二哈希值，所述第二哈希值用于指示所述服务器所述第二哈希值对应的第二绘制资源在所述用户设备中已保存，以使所述服务器根据所述第二哈希值，确定所述用户设备中未保存的所述第一绘制资源。
或者，所述接收所述服务器发送的中断图像帧的第一绘制资源之前，所述方法还包括：所述用户设备向所述服务器发送第二哈希值，服务器判断所述第二哈希值是否与第一哈希值相等(其中所述第一绘制资源与第一哈希值对应)；所述服务器根据所述判断结果，确定所述用户设备是否保存有所述第一绘制资源。
在本发明的一些实施例中，所述接收所述服务器发送的中断图像帧的第一绘制资源，可以包括：
