为使本发明的实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图对本发明的实施例的技术方案进行清楚、完整的描述。显然，所描述的实施例仅是本发明的一部分示例性实施例，而不是全部的实施例。基于所描述的本发明的示例性实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其它实施例都属于本发明的保护范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本发明所属领域内具有一般技能的人士所理解的通常意义。本发明专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“上”、“下”、等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
一方面，本公开的至少一个实施例提供一种多视角抬头显示系统，其具有至少两个眼盒区域，并且包括图像光线提供装置和控制装置。图像光线提供装置被配置为提供图像光线。控制装置与所述图像光线提供装置相连，用于根据交通工具的状态和/或关注信息的优先关注度，控制所述图像光线提供装置向至少两个眼盒区域提供所述图像光线以实现多视角显示。眼盒(eyebox)区域是指用户能够接收到图像光线而观看到图像画面的位置区域。

例如，第一光线控制装置用于调控第一光产生部发出的第一光线的传播方向，并且使第一光产生部产生的第一光线入射至图像生成层；图像生成层用于使入射至其上的第一光线生成第一图像光线。例如，图像生成层使入射至其上的第一光线在通过图像生成层或被图像生成层反射之后生成第一图像光线。例如，第一图像光线在到达所述预设区域后传播至所述至少两个眼盒区域。
例如，第二图像光线提供装置包括多个第二光产生部和第二光线控制装置，多个第二光产生部配置为产生携带图像信息的第二光线(第二光线为源图像光线)，第二光线控制装置配置为调控第二光线以形成第二图像光线(第二图像光线为调控后的图像光线)。例如，第二光线控制装置用于调控第二光产生部发出的第二光线的传播方向，以得到第二图像光线并且使第二图像光线传播至所述至少两个眼盒区域。例如，第二光线控制装置使第二图像光线在到达预设区域后传播至所述至少两个眼盒区域。
例如，图像光线提供装置被配置为向至少两个眼盒区域投射涉及的图像内容与眼盒区域所处位置相符合的图像光线。涉及图像内容与眼盒区域所处位置相符合的图像光线，是指使得用户通过不同的眼盒区域观察到的图像内容符合驾驶需求和相应眼盒区域处用户的需求。例如，所述至少两个眼盒区域包括第一眼盒区域和第二眼盒区域；传播到涉及驾驶位置的第一眼盒区域的图像光线用于显示的图像内容为与驾驶相关的信息，例如可为速度信息和/或导航信息等；传播到涉及非驾驶位置的第二眼盒区域的图像光线用于显示的图像内容可为与驾驶的相关性较为次要的信息，例如可为社交软件信息和/或娱乐信息等。
例如，控制装置被配置为，根据关注信息，向所述至少两个眼盒区域中的至少一个眼盒区域投射出用于将关注信息对应内容与真实场景贴合显示的的图像光线，以提升显示效果。关注信息的对应内容与真实场景贴合显示是指用户从眼盒区域观看到的图像画面中所要显示信息的对应内容对应显示在挡风玻璃展现的真实场景中的预设位置。
在一些实施例中，控制装置被配置为控制图像光线在图像画面中的显示方式包括主 要显示方式和次要显示方式，主要显示方式为与次要显示方式相比使用户更快获取或关注显示内容的显示方式。例如，图像画面包括关键区域和边缘区域，在主要显示方式中显示内容被显示在关键区域，在次要显示方式中显示内容被显示在边缘区域。

在一些实施例中，多视角抬头显示系统还可以包括传感装置和/或监测装置和/或其它装置。这些装置的设置方式参见说明书中下述相关描述。
又一方面，本公开至少一个实施例还提供一种多视角抬头显示方法，其用于上述多视角抬头显示系统，该方法包括：获取交通工具的驾驶信息并且根据驾驶信息判定交通工具的状态；基于关注信息与安全驾驶或者用户的相关度之间的关系评估关注信息的优先关注度；根据交通工具的状态和/或关注信息的优先关注度，向交通工具内的至少两个眼盒区域提供图像光线，所述图像光线包含的图像内容与至少两个眼盒区域所处位置相符合。
再一方面，本公开至少一个实施例还提供一种交通工具，其包括本公开实施例提供的多视角抬头显示系统。

本公开实施例提供的多视角抬头显示系统中，图像光线提供装置提供具有经调控的传播方向的图像光线，控制装置根据交通工具状态和/或关注信息的优先关注度，控制所述图像光线提供装置分别向至少两个眼盒区域提供包括的图像内容与眼盒区域所处位置相符合的图像光线。一方面，本公开实施例提供的多视角抬头显示系统能够向交通工具内对应于不同视角的不同眼盒区域显示图像画面，另一方面，本公开实施例能够根据交通工具的状态分别向不同眼盒区域显示出与该眼盒区域位置相符合的图像画面。
例如，向至少两个眼盒区域投射出包括的图像内容与眼盒区域所处位置相符合的图像光线，是指使得用户通过不同的眼盒区域观察到的图像符合驾驶需求和相应的眼盒区域处用户的需求。例如，所述至少两个眼盒区域包括第一眼盒区域和第二眼盒区域；传播到涉及驾驶位置的第一眼盒区域的图像光线用于显示的图像内容为与驾驶相关的信息，例如可谓车速和/或导航等；传播到涉及非驾驶位置的第二眼盒区域的图像光线用于显示的图像内容可为与驾驶的相关性较为次要的信息，例如可为社交软件信息和/或娱乐信息等，这可确保相应的眼盒区域涉及的图像满足与该眼盒区域相对应的需求，且又不会影响正常的驾驶。
例如，图1A和1B分别为本公开实施例提供的多视角抬头显示系统的两种示范性实施例的结构示意图。图1A-1B中的系统至少部分包括图像光线提供装置和控制装置。图1A所示的图像光线提供装置是基于例如被动像源的第一图像光线提供装置，而图1B所示的图像光线提供装置是基于例如主动像源的第二图像光线提供装置。

下面结合具体实施方式和附图对本公开实施例提供的多视角抬头显示系统中的图像光线提供装置进行详细说明。
例如，在本公开的一种实施例的多视角抬头显示系统中，图像光线提供装置可包括第1至第M组光产生部以及第1至第M光线控制装置，第i光线控制装置与第i组光产生部对应，每一组光产生部包括至少两个光产生部。
例如，对于例如图1A所示的第一图像光线提供装置，还包括图像生成层12，控制装置分别与第一光线控制装置以及图像生成层12相连，例如，第一光线控制装置和图像生成层12可以各自与控制装置连接，或者第一光线控制装置通过图像生成层连接控制装置，例如，图像生成层12与第一光线控制装置之间的连接可以是机械连接或者信号连接，例如，控制装置与第一光线控制装置以及图像生成层12中的每个之间的相连可以通过WiFi、信号传输、蓝牙、ZigBee、光通信等的无线方式进行连接，实现通信连接和数据传输；或者也可通过例如数据线的有线方式实现数据传输，本公开的实施例对此不做限定。
例如，图像生成层12包括第1至第M区域；第i个第一光线控制装置配置为使第i组第一光产生部11中的各个第一光产生部11产生的第一光线通过所述图像生成层12的第i区域，以向至少两个眼盒区域中包括的第1至第M眼盒区域中的第i眼盒区域提供。
例如，对于例如图1B所示的第二图像光线提供装置，其不需要设置图像生成层，控制装置与第二光线控制装置相连，例如，控制装置与第二光线控制装置相连可以通过WiFi、信号传输、蓝牙、ZigBee、光通信等的无线方式进行连接，实现通信连接和数据传输；或者也可通过例如数据线的有线方式实现数据传输，本公开的实施例对此不做限定。
第1至第M组第二光产生部11分别产生相同的第二光线或者不同的第二光线；第i光线控制装置用于将第i组第二光产生部11的各个第二光产生部11产生的第二光线向所述至少两个眼盒区域包括的第1至第M眼盒区域中的第i眼盒区域提供；相同的第二光线是指第二光线携带的图像信息相同，不同的第二光线是指第二光线携带的图像信息不同。
对于上述任一实施例，i∈[1，M]，M为大于等于2的正整数，第1至第M眼盒区域分别为对应交通工具内不同区域的不同的眼盒区域。
例如，请参考图2A和图2B，图2A为图1A所示系统中第一图像光线提供装置包括两组第一光产生部100和第一光线控制装置101、102的示意图，图2B为图2A所示的系统的光线传播示意图。由图2A-2B可看出，所述第一图像光线提供装置可包括第1组第一光产生部100、第2组第一光产生部100、第1个第一光线控制装置101、第2个第一光线控制装置102和图像生成层12，其中第1组第一光产生部100和第2组第一光产生部100分别包括多个第一光产生部100。第1个第一光线控制装置101将第1组第一光产生部100的各个第一光产生部100产生的第一光线通过图像生成层12的第1区域并经挡风玻璃10反射后，出射到第1个眼盒区域131。第2个第一光线控制装置102将第2组第一光产生部100的各个第一光产生部100产生的光线通过图像生成层12的第2区域并经挡风玻璃10反射后，出射到第2个眼盒区域132。
图2A和图2B所示的多视角抬头显示系统是以包括两组第一光产生部100和两个第一光线控制装置101、102为例说明的，可以理解的是，在一些实际应用中，基于与图2A和图2B所示实施例相同的原理，多视角抬头显示系统可以包括其它数量的第一光产生部100和第一光线控制装置131、132，以实现满足实际应用要求的多视角显示。
在一些实际应用中，例如每个眼盒区域可以观察到不同的图像。如图2B所示，每个眼盒区域对应图像生成层12的不同区域，最终可观察到不同的图像，或者也可以观察到相同的图像。
例如，请参考图3，图3为图1B所示系统中第二图像光线提供装置包括两组第二光产生部100和两个第二光线控制装置101和102的示意图。由图3可看出，第二图像光线提供装置不设置图像生成层，第二光产生部100发出的第二光线分别经两个光线控制装置101、102调控后提供至挡风玻璃10，再经挡风玻璃10反射后分别提供至第1和第2眼盒区域131、132。
例如，图4为本公开的至少一实施例的多视角抬头显示系统的图像光线提供装置中光线控制装置的另一实施例的示意图。与图2A-图3所示不同的是，本公开的至少一实施例中的光线控制装置用于将各个光产生部发出的光线扩展为N个传播方向不同的光扩散区域，以使得各个光扩散区域经挡风玻璃反射后，分别提供至至少两个眼盒区域中的N个不同的眼盒区域，N为大于等于2的正整数。例如，本公开的至少一实施例的光线控制装置适用于第一图像光线提供装置和第二图像光线提供装置二者。
本实施方式中的光线控制装置能够将入射光线扩展为N个传播方向不同的光扩散区域。例如，第一光线控制装置被配置为将多个第一光产生部产生述第一光线扩展为包括传播方向不同的N组第一扩散光线，以使得N组第一扩散光线通过图像生成层后，以图 像光线包括的N组传播方向不同的第一图像扩散光线的形式分别向至少两个眼盒区域中的N个不同的眼盒区域提供，N为大于等于2的正整数；和/或第二光线控制装置被配置为将多个第二光产生部产生的第二光线扩展为图像光线包括的传播方向不同的N组第二图像扩散光线，以使得N组第二图像扩散光线分别向至少两个眼盒区域中的N个不同的眼盒区域提供，N为大于等于2的正整数，在这里，N组图像扩散光线与N个不同的眼盒区域一一对应。
请参考图4，图4为光线控制装置将光线扩展为两个光扩散区域的示意图。由图4可看出，本公开的至少一实施例中的光线控制装置将入射光线扩展为2个光扩散区域200和201，光扩散区域200经挡风玻璃10反射后会聚至第1眼盒区域，光扩散区域201经挡风玻璃10反射后会聚至第2眼盒区域，从而实现向第1眼盒区域和第2眼盒区域分别投射出图像光线。在实际应用中，可以根据实际应用需求确定扩展后的光扩散区域数量以及各个光扩散区域的形状，本公开的至少一实施例中不做具体限定，其中通过对光线控制装置进行光学设计，能够改变扩展的光扩散区域数量和光扩散区域形状。在此需要说明的是，图4示意性地示出了基于被动像源的第一图像光线提供装置的实施例，例如包括图像生成层12；在基于主动像源的第二图像光线提供装置的实施例中，该图像生成层12可省略。
根据本公开的至少一实施例，例如，图像光线提供装置中的光产生部可以是电致发光器件，比如发光二极管(Light Emitting Diode,LED)、白炽灯、激光、量子点光源等，例如可以是有机发光二极管(Organic Light-Emitting Diode,OLED)、迷你发光二极管(Mini LED)、微发光二极管(Micro LED)、冷阴极荧光灯管(Cold Cathode Fluorescent Lamp，CCFL)、电致发光显示器(Electroluminescent Display,ELD)、LED冷光源(Cold LED Light，CLL)、电激发光(Electro Luminescent，EL)、电子发射(Field Emission Display，FED)、卤钨灯或者金属卤化物灯等。
在采用被动像源的第一图像光线提供装置的实施例中，例如，图像生成层12可以是液晶层，液晶层例如可以是扭曲向列型(Twisted Nematic,TN)液晶、高扭曲向列型(High Twisted Nematic,HTN)液晶、超扭曲向列型(Super Twisted Nematic,STN)液晶、格式化超扭曲向列型(Formated Super Twisted Nematic,FSTN)液晶等，液晶层或者也可以为蓝相液晶。
例如，包括第一图像光线提供装置的多视角抬头显示系统可包括液晶显示系统，其中第一光产生部可由该液晶显示系统的光源充当，图像生成层12可由该液晶显示系统的液晶层充当，并且光线控制装置可以设置在该液晶显示系统的背光模组内。
例如，在采用主动像源的第二图像光线提供装置的实施例中，多个第二光产生部按照预设规则排布，例如，控制各个第二光产生部的发光亮度、颜色等产生图像光线。例如，为了均衡光线利用率和空间利用率，多个第二光产生部可以采用完全紧密堆积的方式排列。当多个第二光产生部的排列形状为矩形或六边形(优选为正六边形)或三角形(优选为正三角形)时，可以实现完全紧密堆积排列。例如，可将多个LED紧密排列，例如，控制各个LED的发光亮度、颜色等产生图像光线。
例如，完全紧密堆积可以指相邻的第二光产生部之间没有间隙或者相邻的第二光产生部之间的间隙小于预设间隙，预设间隙可根据实际制作需求自行进行设定，本公开的实施例对此不做限定。
例如，包括第二图像光线提供装置的多视角抬头显示系统中的第二光产生部可为LED显示器，相应地，第二光线控制装置可设置在LED显示器模组上。
下面将结合具体实施方式和附图对该多视角抬头显示系统的光线控制装置的光学结构做进一步详细说明。
图5-图7为根据本公开的至少一实施例的多视角抬头显示系统中基于被动像源的第一图像光线提供装置的第一光线控制装置的示意图。由图5-图7中可看出，本公开的至少一实施例中的第一光线控制装置主要包括第一光学部301、第二光学部302和第三光学部303。第一光学部301用于将所述第一光产生部300发出的第一光线以及由所述第二光学部302返回的第一光线至少部分地反射至所述第二光学部302；所述第二光学部302在第一光产生部300发出的光线的传播方向上是双向透光的结构，用于将通过其的第一光线中的第二特性光线至少部分转换为第一特性光线；所述第三光学部303允许所述第二光学部302的出射的第一光线中的第一特性光线通过，例如，第三光学部303将所述第二光学部302的出射的第一光线中的第二特性光线至少部分反射回所述第二光学部302。
例如，第一光学部301可采用方向控制元件，所述方向控制元件对应一个所述第一光产生部300或者多个所述第一光产生部300。方向控制元301可以包括作为反射面的凹面，所述光产生部300位于凹面所围的区域内。例如，方向控制元件301可以是设置有内凹面的基板，第一光产生部300所在平面与基板的内凹面相切，通过设置基板的形状可以调整第一光产生部300的主光轴方向。例如，方向控制元件301可以包括透镜，透镜的光轴与其所对应的第一光产生部300发出的光线的主光轴具有夹角，利用透镜光轴的朝向实现对第一光产生部300产生光线主光轴的调整。
本公开的至少一实施例提供的多视角抬头显示系统中，通过第二光学部302和第三 光学部303将第一光产生部300产生的第一光线中原本需要过滤掉的第二特性光线转换为所需要的第一特性光线并透射该第一特性光线，提高了第一光产生部300产生的第一光线的利用率和透光率。使得通过小功率光源可以透出高亮度光线，方便后续高亮度成像，在需要发出相同亮度时，传统光源需要具有较大功率，功耗较高，而本公开的至少一实施例中通过光线控制装置对光具有高利用率，可以减小光源能耗；同时由于透光率提高，光线控制装置不会吸收大量的光能，发热量较小，对散热要求较低。
例如，上述光线特性可以是偏振特性，第二光学部302为转换通过光线的偏振态的光学元件，第一特性光线为第一偏振态光线，第二特性光线为第二偏振态光线。例如，第二光学部302可以是通过改变光线的相位而实现改变光线的偏振态的光学元件。例如，第二光学部302包括但不限于1/4波片、1/8波片或1/16波片。例如，请结合参考图5，第二光学部302和第三光学部303依次位于第一光产生部300的同一侧。第一光产生部300发出第一光线AB，第一光线AB为自然光；自然光的第一光线AB经1/4波片302后转换为大量的具有各种长短轴比例的椭圆偏振光的集合，但仍然是自然光，即仍然为第一光线AB。自然光可以分解为第二线偏振光和第一线偏振光。当第一光线AB出射至第三光学部303后，其中的第一线偏振光(即第一特性的光线A)可以透过该第三光学部303，第二线偏振光(第二特性的光线B)被反射至1/4波片302，即：光线B被反射至1/4波片302。之后，光线B透过1/4波片302后转换为圆偏振光(即光线C)，圆偏振光的光线C再经第一光学部301反射后再次透过1/4波片302，1/4波片302将圆偏振光的光线C转换为第一线偏振光(即光线D)，此时光线D与光线A至少部分为第一线偏振光，即：第二线偏振的光线B经过两次透过1/4波片302后可以转换为第一线偏振光，从而使光线D或者也可以透过第三光学部303。在不考虑其他损耗的情况下，第一光产生部300发出的第一光线可以完全以第一线偏振光的形式(包括光线A和光线D)发出，大大提高了光源发光的利用率。
例如，上述光线特性或者也可以是波长特性，第二光学部302为转换通过光线的波长范围的光学元件，第一特性光线为波长大于预设波长值的光线，第二特性光线为波长不大于预设波长值的光线。请结合参考图6，第二光学部302和第三光学部303位于第一光产生部300的不同侧。本公开的至少一实施例的第二光学部302例如可由荧光粉制成，用于发出特定波长的光线，例如发出波长大于400nm的光线。第一光产生部300发出的第一光线AB是具有较宽波段的光线，包括长波长光线A(例如可见光)和短波长光线B(例如紫外光)；第三光学部303例如可为长波长通过滤片，即：长波长光线A可以透过第三光学部303，而短波长光线B被会第三光学部303反射回去，并射向第二光 学部302。第二光学部302例如可以由荧光粉制成。荧光粉受到激发可发出特定波长的光线，例如，在短波紫外线激发下可以发出长波长的可见光，例如，发出波长大于400nm的光线。利用此特性，可以将短波长光线B直接转换为长波长光线D，并通过第三光学部303发射出去。同时，由于荧光粉的反射率不高，短波长光线B还可透过该第二光学部302形成光线C，之后光线C经过第一光学部301的作用再次透过第二光学部302，并转换为长波长光线D，最后通过第三光学部302发射出去。本公开的至少一实施例中，通过光特性转换元件将紫外光转换为可见光，从而提高对第一光线的利用率，并提高成像亮度。
例如，参考图7A所示，第一光线控制装置还包括光线会聚元件305，所述光线会聚元件305用于将第一光产生部300的出射的第一光线会聚，以使得第一光线通过所述图像生成层并经挡风玻璃反射后传播至眼盒区域。本公开的至少一实施例中的光线会聚元件305可设置在第三光学部303远离第二光学部302一侧。通过光线会聚元件305将光线聚焦在预设位置310，可使观察者在光线聚焦位置310观察到完整图像，且由于光线聚集，成像亮度更高，进一步提高成像亮度，提高光线利用率。例如，光线会聚元件305例如可以为菲涅尔透镜、凸透镜或者不同透镜的组合，比如凸透镜与凹透镜的组合、菲涅尔透镜与凹透镜的组合等。
例如，参考图7A所示，第一光线控制装置还可包括光线调控部304，所述光线调控部304用于通过光线扩展调控入射于其上的第一光线的发散角度和/或传播方向，以将所述光线控制装置的出射的第一光线扩展并引导其入射至预设位置310，例如引导至所述图像生成层，进一步扩大了成像范围，以增加观察者观察图像的区域，本公开的至少一实施例中的光线调控部304可设置在第三光学部303远离第二光学部302一侧，例如可以设置在第三光学部303和光线会聚元件305之间。例如，光线调控部304可以是衍射光学元件(Diffractive Optical Elements,DOE)，比如为光束整形片(beam shaper)。本公开的至少一实施例中，光线调控部304将光线扩展后形成的光斑大小和形状由光束整形片的微观结构所决定，光斑的预设形状包括但不限于圆形、椭圆形、正方形、长方形或者蝙蝠翼形状。
例如，图5-图7所示实施例中提供的第一光线控制装置还可包括与第一光产生部300对应设置的准直元件307，如图7B所示。准直元件307可对应一个第一光产生部300或者多个第一光产生部300。准直元件307用于将其所对应的第一光产生部300产生的第一光线的出射方向调整至预设角度范围内。例如，准直元件307可以是准直透镜或者准直膜，准直透镜可以是凸透镜、菲涅尔透镜或者透镜组合中的一种或者多种，透镜组合 可以是但不限于凸透镜与凹透镜的组合、菲涅尔透镜与凹透镜的组合。例如，准直元件307为凸透镜时，可将光产生部设置在凸透镜的焦距处，即：凸透镜与第一光产生部300位置之间的距离为凸透镜的焦距，以使得第一光产生部300发出的不同方向的光线经准直元件307后可以平行射出。可替换地，准直元件307或者也可以为准直膜，比如BEF膜(Brightness Enhancement Film，增亮薄膜)，用于将光线的出射方向调整至预设角度范围内，比如将光线聚集在准直膜法线的±35°的角度范围内。
