Description
本申请要求于2020年12月18日提交中国专利局、申请号为202011505766.7、发明名称为“一种文字显示方法、系统、电子设备和存储介质”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。
本发明拼接屏显示技术领域，更具体地，涉及一种文字显示方法、系统、电子设备和存储介质。
随着社会的发展，互联网信息高速增长，信息的可视化需求也急剧扩张，现有尺寸的屏幕显示已远远不能满足用户需求，显示拼接屏应运而生。显示拼接屏的出现，解决了传统电视幕墙的各种缺陷，为方便、全面、实时地显示各系统视频信息，给远程实时指挥调度等工程应用提供了最好的大屏幕显示系统。显示拼接屏是一个完整的拼接的显示墙体，既能单独使用其中一个屏幕作为显示器，又可以使用全屏作为超大屏幕。根据不同使用需求，实现可变大也可变小的百变大屏功能：单屏分割显示、单屏单独显示、任意组合显示、全屏拼接、竖屏显示，图像边框可选补偿或遮盖。显示拼接屏的安装就像搭积木一样简单，将多个显示屏进行拼接，即可得到完整的成品进行使用。显示拼接屏应有尽有，不仅适应数字信号输入，也支持模拟信号。显示拼接屏系列产品采用独有的以及世界最前沿的数字处理技术，让用户真正体验全高清大屏幕效果。
显示拼接屏作为控制室应用中一个重要的设备，常用于显示各种高分可视化、监控视频、电脑信号等图像内容。另外，控制室因有接待的需求，往往也有跨屏字幕用于显示欢迎词等应用的需求。现有的显示拼接屏为了实现信息可视化，由一台服务器与多个显示节点进行连接，显示节点连接相应的显示屏，显示屏按照一定的数量和布局设置在不同的位置，组成一个显示拼接屏，显示拼接屏显示从显示节点接收到的图像信息。现有的显示拼接屏一般由多个显示屏组成，每个显示屏都有一个与其相对应的显示 节点，在没有协调器协调各个显示节点的情况下，显示拼接屏难以协调每个单独的显示屏，以此实现跨屏字幕的显示。显示跨屏字幕是显示拼接屏的最常用的应用之一，若无法实现会导致显示拼接屏的使用极其不方便。但使用协调器实现跨屏字幕的显示，又会导致设备成本的提高，增加系统资源的消耗。因此，目前亟需一种无需协调器协调实现跨屏显示文字的文字显示方法、系统、电子设备和存储介质。
发明内容
为了解决上述问题，本发明提供一种文字显示方法、系统、电子设备和存储介质，该文字显示方法、系统、电子设备和存储介质无需协调器协调实现跨屏显示文字。
本发明采取的技术方案是：
一种分布式显示文字的方法，包括：
接收显示文字指令、用户输入的文字信息和用户设置的参数信息；
通过用户设置的参数信息对用户输入的文字信息进行图像转换，获取第一文字图像信息；所述第一文字图像信息包括：第一文字图像和第一坐标范围；所述第一坐标范围为拟显示文字图像信息区域相对于显示拼接屏的坐标范围；
根据第一坐标范围和第二坐标范围对第一文字图像进行裁剪和编码，获取第二文字图像信息；所述第二文字图像信息包括：第二文字图像和第三坐标范围；所述第二坐标范围为各显示区域与第一文字图像重叠部分相对于第一文字图像的坐标范围；所述第三坐标范围为各显示区域与第二文字图像的重叠部分相对于显示拼接屏的坐标范围；所述显示拼接屏由多个显示区域组成；
将第二文字图像信息发送给相应的显示节点解码，若显示节点返回无法解码的信息则重新接收显示文字指令、用户输入的文字信息和用户设置的参数信息，否则发送显示文字指令给显示节点，以使显示节点按照显示文字指令将解码后的第二文字图像信息发送到显示拼接屏进行显示；所述显示文字指令携带显示拼接屏显示文字图像信息的开始时间。
具体地，目前显示拼接屏虽然已经实现了跨屏字幕的显示，并且字幕 的清晰度和协调度都能维持在较高的水平上，但是现有的技术在实现显示拼接屏显示跨屏字幕的依然存在许多不足。其中最主要的不足是设备成本偏高，系统资源消耗过大。由于各个显示节点需要协调器进行协调，才能同步地协调地跨屏显示字幕，而协调器这种实现跨屏显示字幕的方式也是导致设备成本偏高，系统资源消耗过大的原因之一。鉴于此，本申请方案在无需协调器的基础上，仅仅依靠多个显示节点来实现跨屏字幕的显示，以此达到降低设备成本，降低系统资源消耗的技术效果。首先，从多个显示节点中选择一个主节点，其余的为次节点。然后，利用主节点接收显示文字指令、用户输入的文字信息和用户设置的参数信息。接着通过用户设置的参数信息对用户输入的文字信息进行图像转换，获取第一文字图像信息；因为每个显示节点都对应拼接显示屏的一个显示区域，因此根据显示拼接屏的各个显示区域对第一文字图像进行裁剪，使第一文字图像分为多个部分，每个部分与其位于的显示区域一一对应。并且根据第一文字图像各部分位于的显示区域对第一文字图像各部分进行编码，以此获取第二文字图像信息。再然后，主节点将第二文字图像信息发送给对应的次节点。次节点将其对应的显示区域内拟显示文字图像的坐标范围与第二文字图像信息含有的第三坐标范围进行对比，若两者一致，则表示第二文字图像信息含有的第二文字图像为显示区域所要显示的第一文字图像的部分，次节点对第二文字图像进行解压，并且将解压后的第二文字图像存入缓存队列，待主节点发送文字显示指令后，在按照指令将第二文字图像发送到显示拼接屏上进行显示；否则表示发送的第二文字图像信息与次节点对应的显示区域不符，返回解压失败信息到主节点。
进一步地，所述参数信息包括：字体大小、文字颜色、背景颜色、字幕滚动方向、字幕滚动速度和窗口；所述窗口为拼接显示屏拟显示文字的区域。
进一步地，所述第一文字图像信息还包括：字幕滚动方向和字幕滚动速度；所述通过用户设置的参数信息对用户输入的文字信息进行图像转换，获取第一文字图像信息包括：
判断文字信息的长度是否大于预设的阈值，若大于阈值，则对文字信息进行多段拆分，按照用户设置的字体大小、文字颜色和背景颜色将多段 文字信息依次转换成图像，作为第一文字图像，否则按照用户设置的字体大小、文字颜色和背景颜色将文字信息转换成图像作为第一文字图像；
通过用户设置的窗口的坐标范围获取第一坐标范围。
具体地，当接收的文字信息的长度大于预设的阈值时，主节点还对文字信息进行多段拆分，之后再依次将每段文字信息按照参数信息进行图像转换，以此转换成多张文字图像，多张文字图像都作为第一文字图像。

本发明附图仅用于示例性说明，不能理解为对本发明的限制。为了更好说明以下实施例，附图某些部件会有省略、放大或缩小，并不代表实际产品的尺寸；对于本领域技术人员来说，附图中某些公知结构及其说明可能省略是可以理解的。
实施例
本实施例提供一种分布式显示文字的方法，图1为本发明的流程图，如图所示，包括：
接收显示文字指令、用户输入的文字信息和用户设置的参数信息；
通过用户设置的参数信息对用户输入的文字信息进行图像转换，获取第一文字图像信息；所述第一文字图像信息包括：第一文字图像和第一坐标范围；所述第一坐标范围为拟显示文字图像信息区域相对于显示拼接屏的坐标范围；
根据第一坐标范围和第二坐标范围对第一文字图像进行裁剪和编码，获取第二文字图像信息；所述第二文字图像信息包括：第二文字图像和第三坐标范围；所述第二坐标范围为各显示区域与第一文字图像重叠部分相对于第一文字图像的坐标范围；所述第三坐标范围为各显示区域与第二文字图像的重叠部分相对于显示拼接屏的坐标范围；所述显示拼接屏由多个显示区域组成；
将第二文字图像信息发送给相应的显示节点解码，若显示节点返回无法解码的信息则重新接收显示文字指令、用户输入的文字信息和用户设置的参数信息，否则发送显示文字指令给显示节点，以使显示节点按照显示文字指令将解码后的第二文字图像信息发送到显示拼接屏进行显示；所述显示文字指令携带显示拼接屏显示文字图像信息的开始时间。
具体地，目前显示拼接屏虽然已经实现了跨屏字幕的显示，并且字幕的清晰度和协调度都能维持在较高的水平上，但是现有的技术在实现显示拼接屏显示跨屏字幕的依然存在许多不足。其中最主要的不足是设备成本偏高，系统资源消耗过大。由于各个显示节点需要协调器进行协调，才能同步地协调地跨屏显示字幕，而协调器这种实现跨屏显示字幕的方式也是导致设备成本偏高，系统资源消耗过大的原因之一。鉴于此，本申请方案 在无需协调器的基础上，仅仅依靠多个显示节点来实现跨屏字幕的显示，以此达到降低设备成本，降低系统资源消耗的技术效果。首先，从多个显示节点中选择一个主节点，其余的为次节点。然后，利用主节点接收显示文字指令、用户输入的文字信息和用户设置的参数信息。接着通过用户设置的参数信息对用户输入的文字信息进行图像转换，获取第一文字图像信息；因为每个显示节点都对应拼接显示屏的一个显示区域，因此根据显示拼接屏的各个显示区域对第一文字图像进行裁剪，使第一文字图像分为多个部分，每个部分与其位于的显示区域一一对应。并且根据第一文字图像各部分位于的显示区域对第一文字图像各部分进行编码，以此获取第二文字图像信息。再然后，主节点将第二文字图像信息发送给对应的次节点。次节点将其对应的显示区域内拟显示文字图像的坐标范围与第二文字图像信息含有的第三坐标范围进行对比，若两者一致，则表示第二文字图像信息含有的第二文字图像为显示区域所要显示的第一文字图像的部分，次节点对第二文字图像进行解压，并且将解压后的第二文字图像存入缓存队列，待主节点发送文字显示指令后，在按照指令将第二文字图像发送到显示拼接屏上进行显示；否则表示发送的第二文字图像信息与次节点对应的显示区域不符，返回解压失败信息到主节点。
进一步地，所述参数信息包括：字体大小、文字颜色、背景颜色、字幕滚动方向、字幕滚动速度和窗口；所述窗口为拼接显示屏拟显示文字的区域。
进一步地，所述第一文字图像信息还包括：字幕滚动方向和字幕滚动速度；所述通过用户设置的参数信息对用户输入的文字信息进行图像转换，获取第一文字图像信息包括：
判断文字信息的长度是否大于预设的阈值，若大于阈值，则对文字信息进行多段拆分，按照用户设置的字体大小、文字颜色和背景颜色将多段文字信息依次转换成图像，作为第一文字图像，否则按照用户设置的字体大小、文字颜色和背景颜色将文字信息转换成图像作为第一文字图像；
通过用户设置的窗口的坐标范围获取第一坐标范围。
具体地，当接收的文字信息的长度大于预设的阈值时，主节点还对文字信息进行多段拆分，之后再依次将每段文字信息按照参数信息进行图像 转换，以此转换成多张文字图像，多张文字图像都作为第一文字图像。
图2为本发明的显示拼接屏示意图，如图所示，假设将文字信息拆分为n段，n>＝1，每段的文字信息转化为文字图像的分辨率分别是W
1*H、W
2*H……W
n*H，那么第n段文字信息转化文字图像相对于显示拼接屏的坐标范围为[sum(W
0：W
n-1)，0，W
n，H]。W
n大于显示节点对应的显示区域的宽度。其中，W-Width，H-high。
进一步地，所述第二文字图像信息还包括：字幕滚动方向和字幕滚动速度；所述根据第一坐标范围和第二坐标范围对第一文字图像进行裁剪和编码，获取第二文字图像信息包括：
通过第一坐标范围将第一文字图像拷贝到窗口；
根据第二坐标范围对第一文字图像进行裁剪；
根据第三坐标对裁剪后的第一文字图像进行编码，获取第二文字图像。
具体地，若第一文字图像为多张图像，则按照文字信息多段拆分的顺序，依次将图像拷贝到窗口，再依次对其进行裁剪，以及编码，获取第二文字图像；所述第二文字图像包含有多张图像。
进一步地，所述将第二文字图像信息发送给相应的显示节点解码，所述解码过程包括：
显示节点从第二文字图像信息中获取第三坐标范围；
显示节点把第三坐标范围和第四坐标范围进行对比，若两者相符，则对第二文字图像进行解码，否则返回无法解码的信息；所述第四坐标范围为各显示节点对应的显示区域拟显示文字图像信息区域相对于显示拼接屏的坐标范围。
进一步地，所述显示节点按照显示文字指令将解码后的第二文字图像信息发送到显示拼接屏进行显示包括：
显示节点计算显示拼接屏显示文字图像信息的开始时间和系统当前时间之间的时间差；
显示节点根据时间差和解码后的第二文字图像、字幕滚动方向和字幕滚动速度获取当前窗口内的像素点；
显示节点根据当前窗口内的像素点从第二文字图像中提取出相应的部分图像；
显示节点将从第二文字图像中提取出相应的部分图像发送到显示拼接屏进行显示。
具体地，次节点接收到显示文字指令后，还执行以下步骤：首先，获取显示文字指令携带的显示拼接屏显示文字图像信息的开始时间和系统当前时间，计算出两者之间的时间差；然后根据时间差和字幕滚动方向、字幕滚动速度，获取窗口内几个点的像素；之后，在第二文字图像上获取相同像素的点，根据这几个像素点从第二文字图像中提取出相应的部分图像；最后将此部分的图像发送至显示拼接屏进行显示。若第二文字图像为多张图像，则从显示文字指令获取第二文字图像内每张图像拟在显示拼接屏显示的开始时间，计算该时间和系统当前时间的时间差，从时间差判断第二文字图像中当前应显示的为哪张图像。然后根据时间差和字幕滚动方向、字幕滚动速度，获取窗口内几个点的像素；之后，在第二文字图像中当前应显示的图像上获取相同像素的点，根据这几个像素点从该图像中提取出相应的部分图像；最后将此部分的图像发送至显示拼接屏进行显示。
