技术领域
本发明实施例涉及计算机技术领域，尤指一种移动轨迹的绘制方法、终端、装置及计算机可读存储介质。
背景技术
在视频会议系统中，电子白板的利用可以有效提升会议多端用户的交流，提升视频会议参与者的体验。
在一些情形中，在进行移动轨迹绘制时，基于Linux的自由及开放源代码的android系统接收用于绘制移动轨迹的触摸移动事件，并根据触摸移动事件进行移动轨迹的绘制。
然而，由于android系统本身的移动轨迹绘制机制复杂，无法实时根据触摸移动事件进行移动轨迹的绘制，当终端进行移动轨迹的绘制时所基于的触摸移动事件可能是多个，因此移动轨迹的绘制会存在较大时延，从而降低用户体验。
发明内容
有鉴于此，本发明实施例提供了一种移动轨迹的绘制方法、终端、装置及计算机可读存储介质。
本发明实施例提供了一种移动轨迹的绘制方法，包括：终端利用自身的本地框架层接收用于绘制移动轨迹的触摸移动事件；其中，所述触摸移动事件包括触摸点的坐标信息；每当接收到一个触摸移动事件，所述终端根据所述触摸点的坐标信息进行移动轨迹的绘制。
本发明实施例还提供了一种终端，包括：接收模块，用于利用所述终端的本地框架层接收用于绘制移动轨迹的触摸移动事件；其中，所述触摸移动事件包括触摸点的坐标信息；处理模块，用于每当接收到一个触摸移动事件，根据所述触摸点的坐标信息进行移动轨迹的绘制。
本发明实施例还提供了一种移动轨迹的绘制装置，包括：处理器和存储器，其中，存储器中存储有以下可被处理器执行的命令：利用终端的本地框架层接收用于绘制移动轨迹的触摸移动事件；其中，所述触摸移动事件包括触摸点的坐标信息；每当接收到一个触摸 移动事件，根据所述触摸点的坐标信息进行移动轨迹的绘制。
本发明实施例还提供了一种计算机可读存储介质，存储有计算机可执行命令，其中，所述计算机可执行命令用于执行以下步骤：利用终端的本地框架层接收用于绘制移动轨迹的触摸移动事件；其中，所述触摸移动事件包括触摸点的坐标信息；每当接收到一个触摸移动事件，根据所述触摸点的坐标信息进行移动轨迹的绘制。
本发明实施例的其它特征和优点将在随后的说明书中阐述，并且，部分地从说明书中变得显而易见，或者通过实施本发明实施例而了解。本发明实施例的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构来实现和获得。
附图说明
附图用来提供对本发明实施例技术方案的进一步理解，并且构成说明书的一部分，与本发明的实施例一起用于解释本发明实施例的技术方案，并不构成对本发明实施例技术方案的限制。
图1为本发明实施例提供的一种移动轨迹的绘制方法的流程示意图；
图2为本发明实施例提供的一种终端的结构示意图；
图3为本发明实施例提供的一种移动轨迹的绘制装置的结构示意图。
图4为本发明实施例提供的一种移动轨迹的绘制装置的结构示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚明白，下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本发明实施例提供一种移动轨迹的绘制方法，如图1所示，包括：
步骤S101、终端利用自身的本地框架层接收用于绘制移动轨迹的触摸移动事件；其中，触摸移动事件包括触摸点的坐标信息。
在某些实例中，本发明实施例接收触摸移动事件通过JNI在本地框架层(native层)直接从触摸设备硬件进行获取。触摸移动事件是触摸事件的一种类型，触摸事件还包括：触摸按下事件和触摸释放事件。
步骤S102、每当接收到一个触摸移动事件，终端根据触摸点的坐标信息进行移动轨迹的绘制。
在某些实例中，本发明实施例提供的移动轨迹的绘制方法通过JNI在本地框架层(native层)实现。
在某些实例中，终端根据触摸点的坐标信息进行移动轨迹的绘制，包括：
终端在显示层(Overlay层)根据触摸点的坐标信息进行移动轨迹的绘制。
在某些实例中，在Overlay层进行移动轨迹的绘制而不是在OSD层进行移动轨迹的绘制可以提高绘制速度，因为在OSD层进行移动轨迹的绘制需要android系统本身利用界面显示功能surfaceflinger绘制，surfaceflinger会存在2桢左右的延时，而在Overlay层进行移动轨迹的绘制则是直接绘制，无需利用surfaceflinger，因此提高了绘制速度。
在某些实例中，终端在Overlay层根据触摸点的坐标信息进行移动轨迹的绘制，包括：
终端在Overlay层根据触摸点的坐标信息，并利用三阶贝塞尔曲线进行移动轨迹的绘制。
在某些实例中，不同于二阶贝塞尔曲线的是加上一个预测点，三阶贝塞尔曲线可以实时绘制到触摸点的坐标信息，从而使得轨迹绘制更加准确。
在某些实例中，当终端处于除自身外还包括其他终端的系统中，触摸移动事件来源于终端自身或者系统中的其他终端。
在某些实例中，当终端处于除自身外还包括其他终端的系统中，且触摸移动事件来源于系统中的其他终端时，还包括：
终端将触摸移动事件进行标记，以便终端确定这个触摸移动事件并不是自身产生的触摸移动事件。
在某些实例中，触摸移动事件来源于终端自身，且当终端处于除自身外还包括其他终端的系统中，终端利用自身的本地框架层接收用于绘制移动轨迹的触摸移动事件之后，还包括：
终端将触摸移动事件发送给系统中的其他终端。
在某些实例中，如果终端处于视频会议系统中，终端将触摸移动事件发送给系统中的其他终端，以使得其他终端利用自身的本地框架层接收用于绘制移动轨迹的触摸移动事件，每当接收到一个触摸移动事件，根据所述触摸点的坐标信息进行移动轨迹的绘制，从而能够实时地进行移动轨迹的绘制。
本发明实施例提供的移动轨迹的绘制方法，由于终端利用自身的本地框架层接收用于绘制移动轨迹的触摸移动事件，每当接收到一个触摸移动事件，终端根据触摸移动事件包括的触摸点的坐标信息进行移动轨迹的绘制，因此实现了移动轨迹的即时绘制，从而极大程度地缩短了移动轨迹的绘制时延，提高了用户体验。
本发明实施例还提供一种终端，如图2所示，该终端2包括：
接收模块21，用于利用所述终端的本地框架层接收用于绘制移动轨迹的触摸移动事件；其中，所述触摸移动事件包括触摸点的坐标信息。
处理模块22，用于每当接收到一个触摸移动事件，根据所述触摸点的坐标信息进行移动轨迹的绘制。
在某些实例中，处理模块22，具体用于在Overlay层根据触摸点的坐标信息进行移动轨迹绘制，并利用三阶贝塞尔曲线进行绘制。
在某些实例中，当所述终端处于除自身外还包括其他终端的系统中，所述触摸移动事件来源于所述终端自身或者所述系统中的其他终端。
在某些实例中，当所述触摸移动事件来源于所述终端自身，且当所述终端处于除自身外还包括其他终端的系统中，处理模块22还用于将所述触摸移动事件发送给所述系统中的其他终端。
本发明实施例提供的终端，由于利用自身的本地框架层接收用于绘制移动轨迹的触摸移动事件，每当接收到一个触摸移动事件，终端根据触摸移动事件包括的触摸点的坐标信息进行移动轨迹的绘制，因此实现了移动轨迹的即时绘制，从而极大程度地缩短了移动轨迹的绘制时延，提高了用户体验。
在实际应用中，所述接收模块21和处理模块22均位于终端中的中央处理器(Central Processing Unit，CPU)、微处理器(Micro Processor Unit，MPU)、数字信号处理器(Digital Signal Processor，DSP)或现场可编程门阵列(Field Programmable Gate Array，FPGA)等实现。
本发明实施例还提供一种移动轨迹的绘制装置，如图3所示，移动轨迹的绘制装置3包括：触摸接收模块31、触摸处理模块32和轨迹显示模块33。
触摸接收模块31，用于接收所属终端的触摸事件或者非所属终端发送过来的触摸事件。
触摸处理模块32，用于处理触摸事件并发送给轨迹显示模块33，
轨迹显示模块33，用于实时绘制触摸点的坐标信息，从而显示移动轨迹。
在某些实例中，触摸接收模块31、触摸处理模块32和轨迹显示模块33都是由Android安装包APK启动的。
本发明实施例还提供一种移动轨迹的绘制装置，如图4所示，移动轨迹的绘制装置4包括：存储器41，处理器42及存储在存储器41上并可在处理器运行的计算机程序，处理器42执行计算机程序时实现上述实施例中任意一种移动轨迹的绘制方法。
本发明实施例还提供一种计算机可读存储介质，存储介质上存储有计算机可执行命令， 计算机可执行命令用于执行如上述实施例中任意一种移动轨迹的绘制方法。
