现有技术中，平面显示的图像在用户转动角度观看后依然是平面的，显示的内容没有视角变化，不是立体图像；而全息投影虽然为真三维立体显示，但成本很高，且均为大型设备，在便携设备上还没有很好的解决方案，另外，投影介质也是比较难处理的，目前多采用特殊液体薄雾或者特殊气体的方法，门槛很高。在不利用这些设备的情况下，用户不能通过裸眼在普通的二维屏幕(如手机屏)上看到3D图像。

具体实施方式
为了使本申请的技术方案及优点更加清楚明白，以下结合附图对本申请的示例性实施例进行进一步详细的说明，显然，所描述的实施例仅是本申请的一部分实施例，而不是所有实施例的穷举。并且在不冲突的情况下，本说明书中的实施例及实施例中的特征可以互相结合。
图1示出了本申请实施例中三维立体显示处理方法，包括：
步骤101，确定用户眼睛到二维屏幕中心点连线与屏幕中心横轴之间的横向方向夹角，和与屏幕中心纵轴之间的纵向方向夹角；
步骤102，根据该横向方向夹角和纵向方向夹角调整图像内容源的图像显示角度；
步骤103，将调整后的图像显示在二维屏幕上。
在实现时，上述三维立体显示处理方法可以由该二维屏幕所在设备来实现，也可以由与该二维屏幕分离的设备(例如服务器)来实现。
为了便于本申请的实施，下面以实施例进行说明。
实施例一：
实施例一以由同一个便携设备来进行用户信息采集、三维立体显示处理为例进行说明。
便携设备的固定前向摄像头能够覆盖设备正前方一定角度范围内的图像，若摄像头可小范围旋转，则可获得更大范围内的图像。实施例一中以便携设备摄像头能够覆盖设备正前方120度角进行举例，即一个顶角为120度垂直于屏幕的圆锥的范围。
实施例一中的图像内容源和全息投影相同，为一个三维立体数据建模(以一个汽车的全息投影为例)。便携设备显示该全息投影的同时摄像头开始侦测人眼与屏幕正表面的双向角度，一个是设备横向的角度，一个是设备纵向的角度。
实施例一中三维立体显示处理方法，如图2所示，包括：
步骤201，便携设备的前向摄像头获取用户眼睛到二维屏幕中心点连线与所述屏幕中心横轴之间的横向方向夹角，和与所述屏幕中心纵轴之间的纵向方向夹角；
图3a示出了便携设备的俯视图，假设用户眼睛到二维屏幕中心点连线与屏幕中心横轴之间的横向方向夹角为a。图3b示出了便携设备的侧视图，假设用户眼睛到二维屏幕中心点连线与屏幕中心纵轴之间的纵向方向夹角为b。当前置摄像头能够识别的最大角度范围是120度时，a和b的最大值为60°，假设图像正面为汽车的正前方视图。
步骤202，根据该横向方向夹角和纵向方向夹角在该二维屏幕上显示图像内容源相应角度的图像。
如图4所示，以汽车的全息投影为例，三维建模也应该取横向方向夹角a，纵向方向夹角b进行三维立体模型到二维屏幕表面的投影，以使用户眼睛能够在屏幕上看到此角度的图像。具体来说，取全息影像投影在与横向方向夹角a，纵向方向夹角b方向上虚拟平面上的投影，并将其作为此时便携设备的显示画面。
基于上述方法，当使用便携设备显示全息影像时，前置摄像头可检测用户眼睛与屏幕的方位进而将该方向的影像图像显示在屏幕上。
实施例二：
在实施例二中，便携设备还接收用户设置的图像旋转角度；
实施例一中根据横向方向夹角a和纵向方向夹角b在二维屏幕上显示图像内容源相应角度的图像时，可以以用户设置的图像旋转角度为显示图像内容源相应角度的图像的基础。
具体来说，用户可手动设置图像的横向和纵向旋转角度(p，q)，其中p表示全息影像中的横向旋转角度，q表示全息影像中的纵向旋转角度。仍然以实施例一中的汽车为例，假设车头正对方向为(0,0)。若用户设置图像旋转角度为(0，0)，即此时以用户的设置为显示图像内容源相应角度的图像的基础，即以车头正对方向(0，0)为基础，用户移动眼睛位置能够看到的是车头正对方向(0,0)上下左右60°角范围内的影像。
当用户手动设置图像旋转角度为(180，0)时，即此时汽车图像横向旋转180度之后，屏幕上显示则是车尾正对的方向。用户移动眼睛位置能够看到的是车尾正对的方向上下左右60°角范围内的影像。
当用户手动设置图像旋转角度为(0，90)时，即此时汽车图像纵向旋转90度之后，屏幕上显示的则是车辆正上方正对的方向。用户移动眼睛位置能够看到的是车辆正上方前后左右60°角范围内的汽车顶部影像。
也就是说在用户手动设置了图像旋转角度(p，q)后，将根据此时的p和a以及q和b判断全息影像应当投影的角度，并将该角度的影像显示在便携设备屏幕上。
实施例三
在实施例一中，由便携设备的前向摄像头获取了用户眼睛到二维屏幕中心点连线与屏幕中心横轴之间的横向方向夹角，和与屏幕中心纵轴之间的纵向方向夹角，这是考虑到可能存在前向摄像头位于屏幕中间的情况，此外， 即使前向摄像头并非位于屏幕中间，实施例一的方案也能够在二维屏幕上提供三维图像显示，与现有技术相比提升了用户体验。
考虑到目前大多数设备的前向摄像头都不在手机横向的正中间，更没有在竖向正中间的，摄像头检测到的用户眼睛到二维屏幕中心点连线与屏幕中心横轴之间的横向方向夹角，和与屏幕中心纵轴之间的纵向方向夹角与实际的夹角会存在误差，因此，若对相应的误差进行校正，则可以进一步提升三维图像显示与用户观看的准确度，提升用户体验。
实施例三中以手机横向的夹角误差为例，如图5所示，假设将摄像头一侧作为180°夹角(前向摄像头在手机正方向左侧还是右侧将影响此方向)：
假设前向摄像头与屏幕中心纵轴的间距为x，这在手机设计时就是确定已知数值，可以通过读取所述设备存储的数据或接收用户的输入来确定。确定户眼睛到二维屏幕中心点连线与屏幕中心横轴之间的横向方向夹角为α，前向摄像头与用户眼睛的连线与摄像头所在横轴之间的横向方向夹角为β，摄像头与用户眼睛距离为l，可以通过摄像头自动对焦测距或激光对焦测距获得摄像头与用户距离为l，两条线到用户眼睛的夹角为γ，用户眼睛到屏幕距离为k。
根据余弦定理可知：
cosβ＝x2+l2–k2/(2*x*l)
进而可推导出：k＝√(x2+l2-2*x*l*cosβ)
再根据正弦定理可知：
k/sinβ＝l/sin(180°-α)
代入计算可得到公式(1)
α＝arcsin(l*sinβ/√(x2+l2-2*x*l*cosβ))
                                                  公式(1)
此α即为用户眼睛到二维屏幕中心点连线与屏幕中心横轴之间的实际横向方向夹角。
同理，也可以根据公式(2)得到用户眼睛到二维屏幕中心点连线与屏幕中心纵轴之间的实际纵向方向夹角α’：
α’＝arcsin(l*sinβ’/√(y2+l2-2*x*l*cosβ’))
                                            公式(2)
