具体实施方式
为了使本公开的目的、技术方案和优点更加清楚,下面将结合附图对本公开作进一步地详细描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,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它实施例,都属于本公开保护的范围。
本公开实施例中术语“和/或”,描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
本公开实施例描述的应用场景是为了更加清楚的说明本公开实施例的技术方案,并不构成对于本公开实施例提供的技术方案的限定,本领域普通技术人员可知,随着新应用场景的出现,本公开实施例提供的技术方案对于类似的技术问题,同样适用。其中,在本公开的描述中,除非另有说明,“多个”的含义是两个或两个以上。
实施例1、随着科技的不断进步,越来越多的可视化设备被添加进日常出行的交通工具中,目前,透明显示设备已经陆续试运行在多种交通场景如地铁中,例如利用透明显示炫窗替代原有的车窗,并通过透明显示炫窗显示丰富的视频流信息,打造一个更具科技感的智慧城市。OSD(on-screen display,屏幕菜单式调节方式)是指按主菜单键后屏幕弹出的显示器各项调节项目信息的矩形菜单,可通过该菜单对显示器各项工作指标包括色彩、模式、几何形状等进行调整。将OSD应用于透明显示炫窗,可以通过OSD菜单,实现 人机交互,控制透明显示炫窗的显示效果。目前,由于透明显示设备外部设有封闭壳体,并安装在车体上,在对透明显示设备的显示效果进行控制时,不便于使用按键或者红外遥控的方式控制OSD菜单,如果使用按键方式,无法避免被非相关人员操作而控制显示效果,不可控因素较多,如果使用红外遥控的方式,由于透明显示设备的封闭性,难以保证红外遥控的及时性、有效性和准确性,无法很好的控制透明显示设备的显示效果,因此,目前通过OSD菜单调节透明显示设备的显示效果的方法,给客户的视觉体验较差,给透明显示设备的维护也带来了一定的困难。
如图1所示,本公开实施例提供一种目前OSD菜单的叠加方案的架构示意图,其中,处理芯片接收SOC通过高清多媒体接口(High Definition Multimedia Interface,HDMI)发送的视频流数据,OSD叠加功能由一个单独的OSD控制板来实现,OSD控制板受按键和红外遥控的控制,处理芯片将接收的视频流数据和OSD控制板发送的OSD数据进行叠加,将叠加处理后的视频流输出到显示端进行显示。但是目前的架构在实际的调测过程中,由于整个系统(包括OSD控制板)密封在车体内,所以按键和红外的控制很难实现,导致OSD叠加控制功能无法实现,无法通过OSD菜单实现相关的显示和视频调节,影响用户和透明显示设备的人机交互体验,不便于后续的操作和维护。
针对目前对透明显示设备进行调测的困难,本公开实施例提供了一种新的人机交互OSD叠加架构,采用主控模块如MCU主控器件作为总控,可以接收前级视频端的控制指令,检测系统的工作状态,从而产生相应的OSD控制菜单,与数据处理模块交互实现视频端的OSD显示功能,而且视频前级支持远程无线网络控制,也可以通过总控系统实时控制主控模块,实现相关的显示和视频调节,达到人机交互的功能,有效的提升了调试的效率,以及后续的操作与维护,实现了实时的人机交互功能,近距离和远距离都可以实现人机交互,有效提高了产品的竞争力,可以用于亮度调节、开关机控制,信息显示等功能,在实际调试和应用中具有很重要的作用。

在一些实施例中,本实施例中的主控模块201和数据源生成模块200基于串行数据通信的接口标准建立通信连接。可选的,主控模块201和数据源生成模块200通过232接口进行通信。

在一些实施例中,所述数据处理模块202对接收的所述OSD数据进行校验,确定校验成功后,将接收到的所述视频流和所述OSD数据进行叠加处理。
在一些实施例中,本实施例中的交互指令包括更新指令;所述主控模块201,还用于接收用户发送的更新指令,根据所述更新指令生成参数,并将所述参数传输给所述数据处理模块202;所述数据处理模块202,用于根据接收的参数控制所述参数对应的数据的更新。
在一些实施例中,本实施例中参数包括OSD参数和视频流参数中的至少一种;所述OSD参数包括显示时长、显示位置、显示透明度中的至少一种;所述视频流参数包括图像亮度、对比度、饱和度、锐度中的至少一种。其中,显示时长、显示位置、显示透明度用于表征实际在显示端显示的OSD菜单的显示时长、显示位置、显示透明度。通过OSD菜单不仅可以对OSD菜单本身进行控制,还可以对视频流的显示进行控制。
实施中,用户可以通过向主控模块201发送携带OSD参数的交互指令,从而通过数据处理模块202控制OSD菜单的显示时长、显示位置、显示透明度等。还可以通过向主控模块201发送携带视频流参数的交互指令,从而通过数据处理模块202控制视频流显示的图像亮度、对比度、饱和度、锐度等。
在一些实施例中,所述交互指令还包括开关机指令,所述主控模块201,用于接收用户发送的开关机指令,控制显示设备如透明显示设备的开机和关机。
在一些实施例中,若本实施例中的数据处理模块202连续两次接收到的OSD数据的时间差值小于阈值,则所述数据处理模块202将接收到的所述视频流和第二次接收到的OSD数据进行叠加处理。实施中,为了避免用户快速切换OSD菜单中的不同功能控制项时,OSD菜单显示响应较慢的问题,本实 施例如果在OSD数据和视频流进行叠加处理的操作期间,数据处理模块202又接收到新的OSD数据,则此时将不对已经叠加处理的OSD数据进行显示,而是重新对新的OSD数据和视频流进行叠加处理,并进行显示。
在一些实施例中,为了降低传输带宽,节约带宽资源,本实施例采用数据存储模块对视频流进行帧率翻倍,实施中,可以基于后端显示器能够显示的视频帧的帧率确定是否对接收的视频流的帧率进行翻倍处理。

步骤1)所述数据处理模块将在接收所述OSD数据后,接收到的视频帧,作为叠加处理的起始帧;
步骤2)根据OSD数据的显示时长,确定叠加处理的视频流的帧数;

步骤3)根据所述起始帧和所述帧数,对所述视频流和所述OSD数据进行叠加处理。

在一些实施例中,如图6所示,本实施例提供一种基于显示设备的人机交互系统的OSD数据叠加的实施流程,其中,以主控模块是MCU模块、数据源生成模块是SOC模块、数据处理模块是FPGA模块、数据存储模块是DDR模块为例,对本实施例提供的OSD数据叠加的实施流程进行如下说明,具体的实施步骤如下所示:
步骤600、整板上电后,MCU模块启动,控制FPGA模块上电。
步骤601、FPGA模块启动后,配置HDMI解析芯片,解析SOC模块发送的HDMI的视频流,同步启动DDR模块,利用DDR模块对视频流的帧率翻倍后,转换成V-BY1格式的视频流输出。
步骤602、FPGA模块在确定接收的所述视频流在显示端按预设要求显示后,向所述MCU模块发送使能信号,以指示所述MCU模块开始执行OSD功能;
如果确定接收的所述视频流在显示端没有按预设要求显示,例如视频流不正常,则需要重新返回步骤601执行配置或查看其他问题。
步骤603、MCU模块在接收到使能信号后,开始配置寄存器并向FPGA模块传输OSD数据。
步骤604、FPGA模块将接收的每个字节的OSD数据存储到RAM中,同步启动校验,在完成全部OSD数据的传输后,比对校验字节,以确定OSD数据传输的正确性。
步骤605、OSD数据校验正确后,进行OSD数据与视频流的叠加处理。
实施中,在OSD数据校验正确后计数新的一帧视频帧的行列,然后参照寄存器模块存储的OSD数据的坐标信息,同步读取RAM中的OSD数据,由于DDR模块对视频流的帧率翻倍,且DDR读取数据位宽96bit(4pixel),所 以为保证同步叠加,每次读取4bit的OSD数据,和一帧视频帧进行叠加处理。
实施中,所述FPGA模块将在接收所述OSD数据后,接收到的视频帧,作为叠加处理的起始帧;根据OSD数据的显示时长,确定叠加处理的视频流的帧数;根据所述起始帧和所述帧数,对所述视频流和所述OSD数据进行叠加处理。
如果显示时长后未接收到新的OSD数据,则正常输出视频流,等待下次叠加操作。如果在叠加操作期间,又有新的OSD数据输入,则需要及时接收新的OSD数据,并对新的OSD数据和视频流进行叠加,并根据新的OSD数据的显示时长重新计算叠加的起始帧和帧数。
实施例2、基于相同的发明构思,本公开实施例还提供了一种显示设备的人机交互方法,由于该方法即是本公开实施例中的系统应用的方法,并且该方法解决问题的原理与该系统相似,因此该方法的实施可以参见系统的实施,重复之处不再赘述。
