三维显示技术主要分为裸眼和非裸眼两大类，非裸眼主要是VR、AR显示技术类，主要代表为Facebook公司的Oculus Quest以及微软的HoloLens眼镜等，其缺点是需要将显示设备佩戴在头上。而现有市场上大多数裸眼三维显示技术只能做到从特定的某一个或少数几个角度来观察三维物体，做不到360度全方位显示，比如Google公司的Project Starline，Sony公司的Spatial Reality Display以及Looking Glass Factory公司的Looking Glass等。其它少数几种可以支持360度裸眼全息显示的技术存在设备体积庞大，分辨率低，颜色少，价格昂贵等缺点，无法进行商业化，目前还只能在实验室里才能看到。
针对上述问题，如何设计一种360度裸眼显示三维物体的实现方法及设备是我们目前迫切需要解决的。

在本发明实施例的描述中，还需要说明的是，除非另有明确的规定和限定，若出现术语“设置”、“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
实施例1
参照图1，图1所示为本发明实施例中一种360度裸眼显示三维物体的实现方法的步骤流程图。
所述方法涉及用于输出三维画面的成像组件，所述成像组件内设有以第一指定速度旋转切换的显示画面；
所述方法包括如下步骤：
S110、所述成像组件以第二指定速度水平旋转，其中，所述第二指定速度与所述第一指定速度相同；
S120、所述成像组件的投射画面以与人眼视线正向垂直的角度射出。
需要说明的是，成像组件旋转的速度必须足够快，让人眼每秒钟至少能看到15帧画面，优选为24帧以上，能减少画面的闪烁感，使画面更加明亮清晰。
在本申请实施例中，上述成像组件内设有以第一指定速度旋转切换的显示画面，在一具体实现中，一方面可以是对需要展现的物体进行三维建模导入成像组件，然后在成像组件中由三维图像引擎软件来实时的根据不同角度渲染输出对应的画面，这种方式对旋转速度的要求不是特别严格，可以快或慢；另一方面也可以预先将需要展示的物体按照固定的旋转速度录像保存为视频，导入成像组件中进行播放，这种方式需要成像组件严格的按照预先定义好的旋转速度进行同步旋转，能降低对成像组件的三维图像处理速度要求。
如上述步骤S110所述“成像组件以第二指定速度水平旋转，其中，所述第二指定速度与所述第一指定速度相同”，具体为，使成像组件里显示的物体角度和组件旋转的角度保持同步，比如在成像组件内展示的物体的 旋转速度为1秒一周，则转轴1转动的速度也为1秒一周，当组件旋转到30度的位置的时候，组件的画面显示的就是从30度角观察物体的画面，从而使观测者能够更加清晰的看到三维物体对应的角度，达到和观察者在真实世界中环绕观测真实的三维物体一致的效果体验。
如上述步骤S120所述“所述成像组件的投射画面以与人眼视线正向垂直的角度射出”，需要说明的是，仅当成像组件旋转到和人眼视线的角度正好为正向垂直90°时的一瞬间，人眼才能看到成像组件上的图像，其它任何偏转角度的画面都不能被看到，也就是说成像组件只能允许和其平面90°正向垂直的光线射出，否则人眼只能看到模糊成一团的画面，无法看到清晰的画面。
本发明通过成像组件内设有以第一指定速度旋转切换的显示画面；成像组件以第二指定速度水平旋转，其中，第二指定速度与第一指定速度相同；成像组件的投射画面以与人眼视线正向垂直的角度射出；通过成像组件以一定的速度高速旋转的过程中，成像组件内部的三维图像画面的旋转速度与成像组件的旋转速度保持同步，从而使成像组件内的三维图像画面的旋转角度对应人眼所看到的每一个实际角度；通过成像组件的投射画面与人眼视线正向垂直的角度射出，以使人眼能看到显示屏3上的三维图像画面，利用视觉的延迟效应，从而将在成像组件外形成一个悬浮的3D三维图像，因此在视觉上呈现出真实的三维图像；本发明技术无需佩戴任何设备，裸眼即能够360度无死角的观看所显示的三维物体，并且能够多人同时观看，具有高分辨率，以及全彩色等优点，同时整体装置制作成本低，具有更容易做到批量化生产的效果。
实施例2
参照图2-图4，示出了本发明实施例中一种360度裸眼显示三维物体的设备的结构示意图；图3为本发明实施例加装安装板的一种360度裸眼显示三维物体的设备的结构示意图；图4为本发明实施例中显示屏成像示意图；
具体包括：成像组件，成像组件内设有以第一指定速度旋转切换的显示画面；
旋转组件，旋转组件用于使成像组件以第二指定速度水平旋转，其中，第二指定速度与第一指定速度相同；
遮光组件，遮光组件用于使成像组件的投射画面以与人眼视线正向垂直的角度射出。
下面，将对本示例性实施例中一种360度裸眼显示三维物体的设备作进一步地说明。
参照图2，在作为一种本实施例中的一种实施方式中，旋转组件包括转轴1，转轴1与成像组件连接并驱动成像组件水平旋转，其中，转轴1的输出端与电机连接。
在作为一种本实施例中的一种实施方式中，上述设备还包括控制器，控制器分别与电机和成像组件信号连接。
在一具体实施例中，上述电机的输出轴与转轴1连接，控制器控制电机以一定的速度高速旋转，以驱动转轴1旋转，从而驱动成像组件旋转；上述控制器将旋转角度数据信号传递给成像组件，成像组件根据角度数据信息显示相应角度的画面。
在作为一种本实施例中的一种实施方式中，成像组件包括至少一组显示单元。
作为一种示例，上述显示单元包括一个显示屏3和一个反射镜4，反射镜4以45°倾斜角倾斜设置于显示屏3的上方，且显示屏3的显示端与反射镜4的镜面端相对设置。
在一具体实现中，参照图4，45°夹角设置能反射出显示屏3的画面，当人眼平视的时候正好把水平的显示屏3反射成直立状态，倾斜角为45°的反射镜4可以将显示屏3显示的画面垂直投影到转盘中央位置。
在作为一种本实施例中的一种实施方式中，上述遮光组件包括多个前挡光板5和多个侧挡光板6，前挡光板5垂直设于显示屏3的外端，其中，前挡光板5的一端与显示屏3的外端连接，另一端与反射镜4的外端连接；多个侧挡光板6沿显示屏3的长度方向间隔设置于显示屏3和反射镜4的两外侧之间，且多个侧挡光板6均与显示屏3所在的平面垂直；前挡光板5和侧挡光板6均用于遮挡显示屏3非垂直射出的光线，以使成像组件只能允许和其平面90°正向垂直的光线射出。
在一具体实施例中，前挡光板5位于显示屏3的外端，并与转轴1平行，参照图2，前挡光板5呈板体结构，前挡光板5开设有用于投射三维画面的通道；其中，前挡光板5开设通道的宽度比显示屏3或反射镜4的宽度小，其高度比反射镜4倾斜后的垂直高度相同，其作用和目的在于优化展示画面，由此能够达到更好的成像效果。
在作为一种本实施例中的一种实施方式中，上述显示单元为一组，即采用一组显示屏3和反射镜4，则需要转轴1每秒转动24圈才能达到24帧每秒的效果；上述显示单元还可以包括多组，即多个显示屏3和多个反射 镜4，由于采用更多组的显示屏3和反射镜4成本也随即增加，例如增加到8组，圈速降低了3圈每秒，但成本高了一倍，并且占用的空间也随即更大，而用四组就可以降到每秒6圈，在进行观测时，24帧将足够看清结构，而旋转速度不需要调整，由于旋转速度提高会加大对屏幕刷新率的要求；因此在本申请实施例中上述成像组件优选为4组显示单元，即包括4个显示屏3和4个反射镜4，多个显示单元以转轴1为圆心，并沿转轴1圆周均匀分布，呈现的画面将以每秒24帧的速度在观察者眼前闪过，进而形成连续流畅的动画视觉效果。
在一具体实现中，显示屏3的数量与反射镜4的数量相同，并且两者之间一一对应，每个反射镜4都反射对应显示屏3所展示的画面，而在转轴1转动时，即能够形成悬浮的三维物体，而观测者能够从多个角度进行观看，并且不用其他物件的辅助，通过裸眼即能够看清，在实际实施和使用时，便捷性更高、实用性更强，并且成本更低。
参照图3，在作为一种本实施例中的一种实施方式中，上述旋转组件包括转轴1和一个安装板2，成像组件安装于安装板2的上端面，在保证具有足够的稳定性时，可以采用一个安装板2，当然，安装板2的数量并不限制，可以一个也可以是多个；转轴1穿设于安装板2的中部并与安装板2垂直设置，多个显示单元以转轴1为圆心，并沿圆心圆周均匀分布，安装板2在转动时，安装板2本身始终是处于水平状态，避免安装板2在转动的过程中，成像组件发生竖直方向上的位移，而影响其成像的效果。
作为一种示例，上述安装板2可以设置为两块，成像组件设置在两块安装板2之间，且两块安装板2相对的一端均与转轴1垂直，两块安装板2的结构，使成像组件的安装具有更高的稳定性。
需要说明的是，由于显示屏3需要在每一个旋转角度显示三维物体对应的角度画面，因此在高速旋转的情况下(360rpm)对图像的换帧要求会非常高；例如，需要偏转每1度角，屏幕就显示不同的画面，那么显示屏3每秒钟需要切换的画面帧数经过计算可以得知：360*6＝2160fps。目前市场上无论是显示器还是显示卡最高都只有几百fps，因而无法满足要求。在这种情况下，我们可以降低切换角度的方式来降低帧数需求，因为人眼对视觉角度的感知不是特别敏感，比如我们可以每旋转6度切换一幅画面，这样每旋转一周只需要显示360/6＝60帧，换帧率也就降低为60*6＝360fps。这样，目前市面上销售的高刷新显示器配合高性能显卡就可以满足要求。
但切换画面的偏转角度太大的话，人眼会感觉在围绕三维物体转动时，三维物体会出现跃变，则会感觉不太真实，因此偏转角度越小越真实，如果追求极限真实感，我们也可以通过定制特殊的显示设备来达到显示屏3的高刷新率。
实施例3
参照图5-图8，图5示出了本发明实施例中一种360度裸眼显示三维物体的设备的结构示意图；图6示出了本发明实施例加装安装板的一种360度裸眼显示三维物体的设备的结构示意图；图7示出了本发明实施例中显示屏一实施方式结构示意图；图8示出了本发明实施例中显示屏另一实施方式结构示意图；本实施例与实施例2的不同之处在于：
参照图5，在作为一种本实施例中的一种实施方式中，上述显示单元包括至少一个显示屏3，显示屏3的显示端面与所述转轴1平行设置。
作为一种示例，遮光组件包括多个百叶挡光板7，多个百叶挡光板7垂直设置于显示屏3的显示端面。
在一具体实施例中，上述多个百叶挡光板7类似于百叶扇面安装于显示屏3的端面，当转轴1转动时，显示屏3会根据转轴1转动的角度显示不断变化角度的三维图像，百叶扇挡光板会挡掉非90度射出的光线，当转轴1转动速度达到每秒12圈时，在围绕转轴1周围任意角度的人会观察到每秒24帧的三维物体的显示画面，这种方式结构简单，有效显示范围广。
作为一种示例，显示单元还可以包括两个显示屏3，两个显示屏3背对背设置。
需要说明的是，一个显示屏3和两个显示屏3所能达到的效果是完全一样的，但是两个显示屏3可以降低一半的转速和屏幕刷新率要求。
在作为一种本实施例中的一种实施方式中，为了进一步降低对屏幕刷新率要求，还可以采用更多屏幕的结构，如图7-图8所示，上述成像组件包括多组显示单元，多个显示单元以转轴1为圆心，首尾连接，并沿其圆心圆周均匀分布。
参照图6，在作为一种本实施例中的一种实施方式中，上述旋转组件还包括转轴1和一个安装板2，转轴1设于安装板2的中部，可穿过安装板2，可嵌入安装板2的一端，安装板2用于固定显示单元，使显示单元在转动时有足够的稳定性，当有多组显示单元时，每组显示单元竖向安装于安装板2上，并绕转轴1的圆心圆周均匀分布，电机设于安装板2的底部，驱动转轴1旋转，从而带动安装板2旋转。
对于本领域技术人员而言，显然本申请不限于上述示范性实施例的细节，而且在不背离本申请的精神或基本特征的情况下，能够以其它的具体形式实现本申请。因此，无论从哪一点来看，均应将实施例看作是示范性的，而且是非限制性的，本申请的范围由所附权利要求而不是上述说明限 定，因此旨在将落在权利要求的等同要件的含义和范围内的所有变化囊括在本申请内。不应将权利要求中的任何附图标记视为限制所涉及的权利要求。
