Description

一种近眼虚拟显示装置及近眼头戴虚拟设备 技术领域
本公开涉及虚拟显示设备领域，尤其涉及一种近眼虚拟显示装置及近眼头戴虚拟设备。
 背景技术
目前，单目和双目的近眼AR（Augmented Reality，增强现实）头戴式显示器（Head-Mounted Display，HMD）广泛用于包括军事、医疗、工业、安防和娱乐等场景。
为了在观看者的预期位置处形成虚拟图像，光学设备必须满足各种几何和位置要求。如用户的眼睛位置、以及光学***相对于用户眼睛的放置。有时用户可能希望虚拟图像内容在视野内与真实世界叠加观察，有时希望虚拟对象在用户眼睛主视区域下方，作为辅助显示，有时用户还希望临时把显示装置收纳起来，不影响用户观察真实世界等等各种使用需求。由于每个人眼睛的瞳距、眼高等视觉特性存在差异，而目前AR虚拟显示器部件包括棱镜、自由曲面、光波导等各种技术都普遍存在FOV（Field of view，视场角）、眼动范围小等问题，且大部分AR产品显示区域空间位置刚性约束太强（例如，眼镜类形态产品还影响原来用户眼镜的佩戴），很难满足不同人头型不同的使用需求，用户也无法很好移动显示区域的空间位置，不能适应使用者的不同角度和方向的调节需要。也有用连杆组合方式来实现头戴显示器的显示器空间位置的调节，但是这种组合方式做出的产品普遍存在体积大、笨重、调节复杂等问题，部分技术方案也存在连接线外露，在一些设备密集或者有限作业空间使用时头部容易被剐蹭，影响用户安全性。
 技术问题
基于此，本公开提供了一种近眼虚拟显示装置及近眼头戴虚拟设备，实现了近眼头戴虚拟显示内容空间位置的高效调节，既提高了用户调节便利性，又节省了产品体积和降低了重量。

本公开实施例中，所述近眼虚拟显示装置与上述任一实施例所述的所述近眼虚拟显示装置10是一致，具体的结构与功能可以参考上述任一实施例所述的所述近眼虚拟显示装置10，在此不再赘述。
所述头戴装置20包括头箍、头盔（安全帽）或者眼镜。
本公开实施例中提供的一种近眼虚拟显示装置10，在与包括头盔（安全帽）、头箍或者眼镜形态的所述头戴装置20组合成近眼头戴虚拟设备时，可以作为单目产品使用，也可以作为双目产品使用。具体请参考如图12至图17所示。
在一个实施例中，所述头戴装置20包括一主机（未图示）和输出接口（未图示），所述主机与所述输出接口连接。优选地，所述输出接口为USB接口。所述主机与通过所述输出接口与所述近眼虚拟显示装置10连接，将主机中的虚拟显示内容传输给所述近眼虚拟显示装置10中的虚拟显示器部件进行显示。
在一个实施例中，所述近眼虚拟显示装置10包括一印刷电路板（PCB，Printed Circuit Board）（未图示），所述印刷电路板可以设置在第一平移调节组件1、第二平移调节组件2或第三平移调节组件3上。

如图18所示，在所述主机与通过所述输出接口与所述近眼虚拟显示装置10连接后，所述MCU控制器通过所述输出接口与所述主机进行通信，获取所述主机下发的控制指令（例如向前平移、向后平移、向上平移、向下平移、向左平移、向右平移等），再将所述控制指令转换为脉冲信号、方向信号和微型电机编号，发送给所述驱动器。所述驱动器根据接收到的所述脉冲信号、方向信号和微型电机编号，驱动相应的微型电机运动，从而达到控制所述近眼虚拟显示装置10的作用，进而达到控制所述头戴装置20的作用。
同时，所述MCU控制器可以把所述近眼虚拟显示装置10调节到最佳位置的数据发送给所述主机，以使所述主机存储最佳位置数据，所述主机下次可以通过下发一次控制指令，即可让所述近眼虚拟显示装置10调整到最佳位置，而无需多次下发控制指令。
所述MCU控制器的控制过程分为三个部分：初始化，中断，主循环。具体如下所述。
初始化部分：上电时，所述MCU控制器先执行初始化操作，复位，使能驱动器，让所有微型电机处于初始化位置。
中断部分：根据控制指令要进行调节的微型电机到达需要调节的终点位置后，所述驱动器会给出终点信号，将所述终点信号发送给所述MCU控制器的中断，所述MCU控制器做相应处理，通过所述输出接口通知所述主机，主机通过显示屏或者语音告知操作人员某个方向已经无法再调节了。
主循环：所述MCU控制器的主循环负责接收所述输出接口发送过来的包含命令码的数据包，解包获取命令码，从命令码中识别出控制指令，将所述控制指令转换为脉冲信号、方向信号和微型电机编号，发送给所述驱动器。所述驱动器根据接收到的所述脉冲信号、方向信号和微型电机编号，驱动相应的微型电机运动。例如，控制指令是“向前”，那么将该控制指令转化为一定的脉冲数，方向是正转，微型电机编号是22’，再把这些控制下发给驱动器，驱动器驱动微型电机22’转动，把所述近眼虚拟显示装置向前推一定的距离。
转化之后的脉冲数、方向和微型电机编号会先在内存缓存起来，当调节完毕之后，使用者认为可以存储当前的近眼虚拟显示装置位置时，那么下发语音指令“存储当前近眼虚拟显示装置位置”或者类似的指令。所述MCU控制器会把调节结果做一个计算，简化操作，比如两次“向前”，一次“向后”，通过计算，仅需要存储一次“向前”的结果即可。计算最佳的调节结果之后，打包，通过输出接口发送给主机进行存储到存储器中，下次开机主机仅下发一次命令，即可把近眼虚拟显示装置调节到最佳位置。

所述主机还内置有语音指令识别APP（Application，应用程序）和近眼虚拟显示装置调节APP。所述语音指令识别APP内置有所述近眼虚拟显示装置10的控制指令（例如向前平移、向后平移、向上平移、向下平移、向左平移、向右平移等），所述语音指令识别APP识别所述麦克风传输过来的语音控制信息，与内置的控制指令进行比对，识别所述语音控制信息对应的控制指令，通过广播方式将所述控制指令告知所述近眼虚拟显示装置调节APP；所述近眼虚拟显示装置调节APP调用相应的接口，通过输出接口下发所述控制指令给所述近眼虚拟显示装置的所述MCU控制器，进而控制相应的微型电机运动。具体过程如下。
所述麦克风采集用户发出的语音控制信息后，传输给所述主机语音指令识别APP；所述语音指令识别APP调用离线语音库文件接口（也可以是在线语音库文件）；所述离线语音库相关接口再根据内置的语音资源文件与采集到的所述语音控制信息做对比，反馈出一个语音识别结果到所述语音指令识别APP；所述语音指令识别APP根据所述语音识别结果，从内置的近眼虚拟显示装置的控制指令匹配出对应的控制指令，将对应的所述控制指令通过广播方式发送告知所述近眼虚拟显示装置调节APP。
所述近眼虚拟显示装置调节APP将接收到的所述控制指令转化为命令码，并将命令码打包成所述MCU控制器可以识别的数据交换格式的包，比如通用的Json包（JavaScript Object Notation，JS对象简谱），或者自定义的数据交换格式的包格式。所述近眼虚拟显示装置调节APP调用相应的驱动层的输出接口驱动（例如输出接口为USB，则输出接口驱动为USB驱动），通过输出接口将包含命令码的数据包发送给所述近眼虚拟显示装置的MCU控制器。
所述MCU控制器识别接收到包含命令码的数据包，解包从命令码中识别出控制指令，将所述控制指令转换为脉冲信号、方向信号和微型电机编号，发送给所述驱动器。所述驱动器根据接收到的所述脉冲信号、方向信号和微型电机编号，驱动相应的微型电机运动。
所述MCU控制器根据所述驱动器的最终调节结果，把调节结果通过所述输出接口反馈给所述近眼虚拟显示装置调节APP，所述近眼虚拟显示装置调节APP把该调节结果存储到本地主机存储器中，下次下发语音命令类似“快速调节所述近眼虚拟显示装置”指令时，所述近眼虚拟显示装置调节APP只要把所述MCU控制器之前反馈回来的调节结果直接下发给所述MCU控制器即可快速调节所述近眼虚拟显示装置，无需下发多次控制指令调节。
需要说明的是，上述近眼头戴虚拟设备实施例与上述近眼虚拟显示装置实施例属于同一构思，其具体实现过程详见近眼虚拟显示装置实施例，近眼虚拟显示装置实施例中的技术特征在所述近眼头戴虚拟设备实施例中均对应适用，重复之处不再赘述。
以上参照附图说明了本公开的优选实施例，并非因此局限本公开的权利范围。本领域技术人员不脱离本公开的范围和实质内所作的任何修改、等同替换和改进，均应在本公开的权利范围之内。
 工业实用性
本公开提供的近眼虚拟显示装置及近眼头戴虚拟设备，通过在近眼虚像可视空间位置范围内，以虚拟显示器部件的眼动范围，出瞳距离为中心，结合男女瞳距、眼高相关统计数据范围，按照覆盖绝大多数人群能够看清虚拟显示器部件的空间变化区域，在近眼虚拟显示装置极小的产品空间体积内，构建以第一平移调节组件、第二平移调节组件、第三平移调节组件的三个平移加以第一旋转调节组件、第二旋转调节组件的两个旋转共五个自由度的空间运动组合方式来可以实现近眼虚拟显示装置在空间位置包括瞳距、眼高、出瞳距离、可视区域角度和位置等的调节变化，实现了近眼头戴虚拟显示内容空间位置的高效调节，从而允许用户方便调节近眼虚拟图像内容的显示位置，不用除去可穿戴显示装置，且不干扰虚拟显示内容的可见性，也不影响用户在佩戴近视眼镜的情况下使用，既可以满足不同头型用户人眼视觉特性和能力差异的需求，还能实现虚拟显示器部件空间位置的变化以满足不同的使用要求；同时在不需要虚拟显示器部件的时候可以快速收纳到不遮挡视线的位置，而不影响正常视野。并且，能够很好的弥补了现有包括棱镜、自由曲面、光波导等各种AR光学技术在眼动范围、FOV小等问题的局限性，满足了工业、医疗等场景下不同头型用户不同视觉特性的多种近眼显示使用需求。相比现有的要由至少两节组合运动调节虚拟显示器部件的连杆组合调节方式，体积小、单手即可操作，灵活、方便，既提高了用户调节便利性，又节省了产品体积和降低了重量。因此，具有工业实用性。
