具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例的主要解决方案是：云终端收集图像数据；云终端对所述图像数据按照预设压缩方式进行压缩，得到压缩数据；云终端将所述压缩数据发送给虚拟机，由所述虚拟机按照与预设压缩方式对应的解压方式解压所述压缩数据，得到解压缩数据。保证了云终端和虚拟机在数据传输过程中对传输带宽和速率的要求。
现有的云终端和虚拟机在数据传输过程中，传输带宽和速率达不到要求，且USB摄像头的映射方案支持的分辨率和支持摄像头的类型有限。
基于上述问题，本发明提供一种方法云终端与虚拟机之间的数据传输方法。
参照图1，图1为本发明数据传输方法的第一实施例的流程示意图。
在一实施例中，所述数据传输方法包括：
步骤S10，云终端收集图像数据；
步骤S20，云终端对所述图像数据按照预设压缩方式进行压缩，得到压缩数据；
步骤S30，云终端将所述压缩数据发送给虚拟机，由所述虚拟机按照与预设压缩方式对应的解压方式解压所述压缩数据，得到解压缩数据。
云终端，是集云计算技术，桌面虚拟化技术，计算迁移与分享概念于一体的智能终端，是一种具备了开源的Linux操作系统，可以介入互联网，能够通过安装运行程序的智能终端。虚拟机是指通过软件模拟的具有完整硬件系统功能的、运行在完全隔离环境中的完整计算机系统。虚拟系统通过生成现有操作系统的全新虚拟镜像，因此具有真实Windows系统完全一样的功能。Windows系统和Linux系统支持同样的用户接口、网络和安 全性，但是Linux事实上是Unix的一种版本。
云终端收集图像数据，并将所述图像数据按照预设压缩方式进行压缩，得到压缩数据；所述云终端将所述压缩数据发送给虚拟机，由所述虚拟机按照与预设压缩方式对应的解压方式解压所述压缩数据，得到解压缩数据。所述预设压缩方式为zlib压缩方式，但是所述预设压缩方式包括但不限于可以实现与zlib压缩方式同样功能的压缩方式。所述zlib是提供数据压缩用的函式库，zlib能使用一个gzip数据头，zlib数据头或者不使用数据头压缩数据。目前zlib仅支持一个LZ77的变种算法，DEFLATE的算法。这个算法使用很少的系统资源，对各种数据提供很好的压缩效果。zlib的函数库提供了对处理器和内存使用控制的能力，不同的压缩级别数值可以指示不同的压缩执行速度，还有内存控制管理的功能。对于zlib压缩和解压缩，没有数据长度的限制，重复调用库函数允许处理无限的数据块，一些辅助代码(计数变量)可能会溢出，但是不影响实际的压缩和解压缩。
本实施例通过云终端收集图像数据；将所述图像数据按照zlib压缩方式进行压缩，得到压缩数据，将所述压缩数据发送给虚拟机，由所述虚拟机按照与所述zlib压缩方式对应的解压方式解压所述压缩数据，得到解压缩数据。保证了云终端和虚拟机在数据传输过程中对传输带宽和速率的要求。
参照图2，图2为本发明方法的第二实施例的流程示意图。基于上述方法的第一实施例，所述云终端插接有USB摄像头；所述云终端收集图像数据的过程可以包括：
步骤S01，云终端接收虚拟机发送的urb网络数据包；
云终端接收由所述虚拟机发送的urb网络数据包，所述urb网络数据包是虚拟机中的USB摄像头应用程序发送的urb数据，由所述虚拟机将所述urb数据包装成urb网络数据包。所述urb是计算机Linux内核术语，是Linux内核中USB驱动实现上的一个数据结构，用于组织每一次的USB设备驱动的数据传输请求，USB请求块urb是USB设备驱动中用来描述与USB设备通信所用的基本载体和核心数据结构，是USB主机和设备通信的“电波”。所述网络数据包，是TCP/IP网络层的封装形式，数据在网络中 传送的时候是有大小的，它的单位从小到大有bit(位)，byte(字节)，M(兆)，G，T。他们的换算方式为1T＝1024G，1G＝1024M，以此类推。而我们通常所说的一个网络数据包就是1M的数据。
所述云终端中都有USB的插拔口，当将USB摄像头插入到云终端时，所述云终端会通过其USB插拔监控程序会监控到有USB摄像头的插入，之后会对插入的USB摄像头进行绑定，绑定之后，所述云终端的上层驱动，即云终端的设备驱动会被云终端的stub驱动所替代，虚拟机的底层驱动，即虚拟机的主控驱动会被虚拟机的vhci驱动所替代。云终端的stub驱动和虚拟机的vhci驱动之间通过网络连接进行数据传输。
云终端通过其stub驱动接收到urb网络数据包，所述云终端通过其stub驱动将所述urb网络数据包解包装成urb数据，通过其USB摄像头的核心驱动，主控驱动将所述urb数据发送给云终端中的USB摄像头。所述urb网络数据包由虚拟机发送给所述云终端。具体过程为：所述虚拟机通过其USB摄像头的应用程序向云终端发送urb数据交互请求，所述虚拟机通过其USB摄像头的设备驱动将所述urb数据发送给其USB摄像头的核心驱动，然后通过其USB摄像头的核心驱动发送给其vhci驱动；所述虚拟机通过其vhci驱动接收到所述urb数据之后，将所述urb数据包装成urb网络数据包，所述虚拟机通过其vhci驱动将所述urb网络数据包发送给云终端。因为urb在Linux中和Windows中的数据表现形式会有所不同，所以在Linux和Windows中传输urb数据时，需要进行将urb数据包装成urb网络数据包，然后再将urb网络数据包解包装成urb数据，使urb数据在Linux和Windows传输中不会照成失误。
步骤S02，云终端根据所述urb网络数据包中的数据请求启动USB摄像头；
具体地，参照图2，所述云终端接收虚拟机发送的urb网络数据包的过程可以包括：
步骤S021，云终端将所述urb网络数据包解包装成urb数据；
步骤S022，根据所述urb数据请求启动USB摄像头。
步骤S03，云终端通过所述USB摄像头收集图像数据。
云终端根据所述urb网络数据包中的数据启动所述USB摄像头，即根 据urb数据启动所述USB摄像头。当所述USB摄像头启动之后，所述云终端通过其USB摄像头根据所述urb数据收集图像数据。当所述云终端通过其USB摄像头收集到所述USB摄像头采集到的图像数据时，将所述图像数据通过其USB摄像头的核心驱动，主控驱动发送给其stub驱动。云终端通过其stub驱动中对所述图像数据按照zlib压缩方式进行压缩，得到压缩数据，将所述压缩数据发送给虚拟机。虚拟机通过其vhci驱动接收到所述压缩数据，在所述vhci驱动中对所述压缩数据按照zlib压缩方式对应的解压方式解压所述压缩数据，得到解压缩数据。虚拟机通过其USB摄像头的核心驱动和设备驱动，将所述解压缩数据发送给其USB摄像头的应用程序，即将所述云终端的USB摄像头所收集到的图像数据发送给虚拟机中的USB摄像头的应用程序。
本实施例通过利用云终端和虚拟机之间的数据传输，在传输USB摄像头收集的图像数据的时候加入zlib压缩算法，这样保证了云终端和虚拟机在传输USB摄像头图像数据过程中对传输带宽和速率的要求，又保证了USB摄像头的通用性。
本发明进一步提供一种云终端和虚拟机之间的数据传输装置。
