因此，如何将一幅大型的全景图像完整的投影出来是本领域技术人员亟待解决的技术问题。
发明内容
本发明实施例的目的在于提供一种图像拼接方法及装置，以展示出大型全景图像的全部内容，进而满足用户观看完整图像的需求。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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他实施例，都属于本发明保护的范围。
本发明实施例提供了一种图像拼接方法及装置，应用于可穿戴式投影设备，下面分别进行说明，首先对一种图像拼接方法进行说明。
需要说明的是，可穿戴式投影设备可以为穿戴在手腕上的手环、手表等，也可以是穿戴在头部的眼镜等，本发明对可穿戴式投影设备的穿戴部位不做限定。在本发明所提供的实施例中，主要以穿戴在手腕上的可穿戴式投影设备为例进行说明，并在下文中以“腕投设备”简称。
如图1所示，本发明实施例提供了一种图像拼接方法，该方法包括如下步骤：
S101、确定用于进行图像拼接的可穿戴式投影设备；
由于本发明是利用多台腕投设备拼接出一幅全景图像，因此，在拼接前，可以将存储有待拼接图像的腕投设备作为主腕投设备，并将主腕投设备作为本方法的执行主体。
主腕投设备可以首先与其他腕投设备建立通信连接，连接后，确定参与图像拼接的腕投设备，需要注意的是，所确定的投影设备中可以包括主腕投设备自身，也可以不包括。
具体的，在所有腕投设备(包括主腕投设备)开启WiFi-Direct功能的前提下，主腕投设备对周围的腕投设备进行搜索并通过WiFi-Direct进行连接，连接后，主腕投设备可以建立一个WiFi-Direct小组，小组中的成员可以仅包括被成功连接的主腕投设备周围的其他腕投设备，也可以还包括主腕投设备本身。
在实际应中，主腕投设备穿戴者可以通过抬起手臂激活WiFi-Direct功能。
具体的，上述WiFi-Direct功能是一种允许无线网络中的设备无需通过无线路由器即可相互连接的通信技术。通常情况下，WiFi-Direct设备通过组建小组(以一对一或一对多的拓扑形式)来建立连接。由其中的一部WiFi-Direct设备负责整个小组，包括控制哪部设备加入、小组何时启动和终止等。这种设备对于传统客户设备而言就是一部接入点，能够提供基础设施接入点所提供的部分服务。
S102、根据所确定的投影设备的数量，将自身存储的待拼接图像分割成所述数量个子图像，其中，所述数量不小于2；
所确定的投影设备的数量即为参与投影的投影设备的数量。
具体的，当主腕投设备与周围的其他腕投设备通过WiFi-Direct功能连接时，所确定的投影设备的数量为步骤S101中的WiFi-Direct小组中的成员数量，为了方便说明，在本发明提供的实施例中，可以将该数量用N表示，N为整数，且N≥2。
主腕投设备可以利用图像处理软件对自身存储的待拼接图像分割成N张子图像，分割后的子图像可以为任意形状。
S103、将所述数量个子图像对应分享至所确定的各个投影设备，以使所确定的投影设备分别对各个子图像进行投影，进而拼接出所述待拼接图像。
需要说明的是，本步骤中“分享”的对象可以是主腕投设备自身，也可以是不包括主腕投设备自身的其他参与投影的投影设备。
当分享的对象不是主腕投设备自身而是其他投影设备时，主腕投设备可以通过主动发送的方式将子图像分享给所确定的各腕投设备，也可以是所确定的各腕投设备主动从主腕投设备上获取子图像以达到分享的目的。
具体的，当WiFi-Direct小组成员中不包括主腕投设备本身时，将N个子图像对应分享给N个其他投影设备，以使N个其他投影设备分别将各个子图像投影至投影屏幕上，进而拼接出所述待拼接图像；
当WiFi-Direct小组成员中包括主腕投设备本身时，将N张子图像中的N-1张子图像对应分享给N-1个其他投影设备，将剩余的一张子图像保留在主腕投设备上，以使主腕投设备与N-1个其他腕投设备一起将相应子图像的投影至投影屏幕上，以拼接出待拼接图像。
图1所示的这种图像拼接方法，可以通过拼接的方式将一幅大型的全景图像完整的投影出来，满足了用户同时观看一幅大型的全景图像的全部内容的需求，提升了用户体验效果。且，相比于传统的投影设备，可穿戴式投影设备体积小巧，便于携带，其投影位置可以被灵活设置，更能满足用户随时随地同时观看一幅大型的全景图像的全部内容的需求。
由于腕投设备投影出的子图像的尺寸大小与该腕投设备距投影屏幕的距离有关，当腕投设备距投影屏幕较近时，投影出的子图像的尺寸较小，当腕投设备距投影屏幕较远时，投影出的子图像的尺寸较大。
因此，当所确定的各腕投设备收到的对应子图像的分辨率相同时，也就是在主腕投设备将待拼接图像分割后直接分享给所确定的各个投影设备时，只有在所确定的各个投影设备与投影屏幕的距离相同的情况下，才能拼接出完整的待拼接图像，否则，会因各子图像相互衔接的部分的尺寸不一致，而无法拼接出待拼接图像。
但是，很多情况下，由于各腕投设备的穿戴者所在的位置是不同的，从而使得所确定的各腕投设备与投影屏幕的距离也是不同的。
为了解决上述问题，优选的，在图1所示的实施例的基础上，所述方法还可以包括：调整所述数量个子图像中相应子图像的分辨率。
具体的，可以根据所确定的各腕投设备与投影屏幕的距离，对相应的子图像的分辨率进行调整，使得接收到相应子图像的各投影设备，在不调整自身与投影屏幕的距离的前提下，通过投影拼接出待拼接图像。
或者，为了解决上述问题，优选的，在图1所示的实施例的基础上，所述方法还可以包括：调整所述数量个子图像中至少一个子图像的分辨率。
具体的，可以对所述数量个子图像中至少一个子图像的分辨率进行任意地调整，使得接收到相应子图像的各腕投设备根据该子图像的分辨率，对自身与投影屏幕的距离进行调整后，再投影出相应的子图像，以拼接出待拼接图像。
上述通过调整子图像的分辨率，以使所确定的各腕投设备根据接收到的子图像的分辨率 调整自身与投影屏幕的投影距离的方案，在满足用户同时观看一幅大型的全景图像的全部内容的需求前提下，可以增加所确定的各腕投设备投影时所在的位置的灵活性，使得腕投设备穿戴者可以随时随地进行投影，使得图像拼接更为方便。
另外，需要说明的是，本发明实施例提供的图像拼接方法，除了能够通过拼接的方式向观看者展示一副大型的全景图像的全部内容，还具有极强的趣味性，例如参与图像拼接的腕投设备可以根据收到的子图像的分辨率对自身的投影距离进行调整，并在几个腕投设备的协作下拼接出一幅完整的图像。因此，本发明实施例提供的图像拼接方法，还可以用于游戏，以丰富人们的业余生活。
如图2所示，本发明实施例提供了另一种图像拼接方法，该方法包括：
S101、确定用于进行图像拼接的可穿戴式投影设备；
同图1所示的实施例中的步骤S101。
S102、根据所确定的投影设备的数量，将自身存储的待拼接图像分割成所述数量个子图像，其中，所述数量不小于2；
同图1所示的实施例中的步骤S102。
S201、根据所确定的投影设备的名称，对所述数量个子图像分别进行命名；
具体的，可以首先对所确定的每一投影设备进行命名，例如，将所确定的各投影设备分别命名为：ASU_1、ASU_2、ASU_3、···、ASU_N；然后将分割获得的N张子图像分别命名为：1、2、3、···、N。
S202、将所述数量个子图像分享至与该子图像名称匹配的所确定的投影设备，以使所确定的投影设备分别对各个子图像进行投影，进而拼接出所述待拼接图像。
具体的，主腕投设备可以将N张子图像分享至名称相互对应的各投影设备。例如，将名为“1”的子图像对应分享给名为“ASU_1”的投影设备，将名为“2”的子图像对应分享给名为“ASU_2”的投影设备，以此类推，直至将N张子图像全部分享至对应的投影设备。
需要说明的是，当所确定的投影设备中包括主腕投设备时，对主腕投设备依照同样的方法进行命名，并将与主腕投设备名称相匹配的子图像保留在主腕投设备上，以使主腕投设备参与图像拼接。
图2所示的这种图像拼接方法，也可以通过拼接的方式将一幅大型的全景图像完整的投影出来，满足了用户同时观看一幅大型的全景图像的全部内容的需求，提升了用户体验效果。且，相比于传统的投影设备，可穿戴式投影设备体积小巧，便于携带，其投影位置可以被灵活设置，更能满足用户随时随地同时观看一幅大型的全景图像的全部内容的需求。
另外，在图1或图2所示的图像拼接方法中的步骤S103或步骤S202中，所述将所述数量个子图像对应分享至所确定的各个投影设备，包括：在监测到穿戴者的第一预设动作时，将所述数量个子图像对应分享至所确定的各个投影设备。
首先，当主腕投设备监测到穿戴者抬起手臂的动作时，再次激活与其他腕投设备的通信连接，例如激活WiFi-Direct功能。然后，在监测到穿戴者的第一预设动作时，将所述数量个子图像对应分享至所确定的各个投影设备。
具体的，当可穿戴式投影设备为腕投设备时，第一预设动作可以为穿戴者的晃动手臂的动作；当可穿戴式投影设备为眼镜时，第一预设动作可以为穿戴者的眨眼动作。例如，当主腕投设备监测到穿戴者晃动手臂的动作时发送当前显示的子图像，同时切换显示下一子图像，对于N张子图像，当检测到N次晃动手臂的动作时，即认为分享过程结束。
相应地，上述任一实施例提供的图像拼接方法，还可以包括：接收所确定的投影设备在监测到穿戴者的第二预设动作后发送的图像分享成功确认消息，以使主腕投设备知晓子图像的分享是否成功。
具体的，接收子图像的腕投设备穿戴者也可以通过抬起手臂的动作激活WiFi-Direct，并通过晃动手臂的动作确认接收相应的子图像。这时，晃动手臂的动作即为第二预设动作。
这种通过监测穿戴者的动作进行通信连接、子图像发送和子图像接收的方式，不仅不需要穿戴者按动投影设备上的操作按钮，使得图像拼接的操作更为简单易行，还提升了穿戴者进行图像拼接时的趣味性。
下面以一个具体的实施例进行说明，在本实施例中，假定所确定的每一投影设备与投影屏幕的距离相等。
请参考图3和图4，图3显示了一幅待拼接的全景图像，图4显示了图3所示的全景图像进行分割后获得的子图像及其名称。
首先，主腕投设备所确定的投影设备的数量为4，并将它们分别名为：ASU_1、ASU_2、ASU_3和ASU_4，其中名为ASU_4投影设备为主腕投设备本身；
相应地，主腕投设备根据所确定的投影设备的数量为及名称，将图3所显示的一幅待拼接的全景图像分割成图4所示的4幅子图像，并分别命名为：1、2、3、4；
然后，主腕投设备将分割获得的4幅子图像按1-4的顺序，对应分享给名为：ASU_1、ASU_2、ASU_3和ASU_4的腕投设备，所确定的4个腕投设备分别对接收到的子图像投影至投影屏幕，即可拼接出图3所示的一幅全景图像。
下面以另一具体的实施例进行说明，在本实施例中，也假定所确定的每一投影设备与投 影屏幕的距离相等。
请参考图5和图6，图5显示了另一幅待拼接的全景图像，图6显示了图5所示的全景图像进行分割后获得的子图像及其名称。
首先，主腕投设备所确定的投影设备的数量为9，并将它们分别名为：ASU_1、ASU_2、ASU_3、···、ASU_9，且所确定的9个投影设备中不包括主腕投设备自身；
相应地，主腕投设备根据所确定的投影设备的数量及名称，将图5所显示的一幅待拼接的全景图像分割成图6所示的9幅子图像，并分别命名为：1-ASU_1、2-ASU_2、3-ASU_3、···和9-ASU_9；
然后，主腕投设备将分割获得的9幅子图像按1-ASU_1至9-ASU_9的顺序，对应分享给名为：ASU_1、ASU_2、ASU_3、···和ASU_9的腕投设备，所确定的9个腕投设备分别对接收到的子图像投影至投影屏幕，即可拼接出图6所示的一幅全景图像。
下面以另一具体的实施例进行说明，在本实施例中，所确定的每一投影设备与投影屏幕的距离需要根据所接收到的子图像的分辨率进行调整。
请参考图5至图7，其中，图7显示了对图6中的每一子图像的分别率进行调整后的子图像及其名称。
首先，主腕投设备所确定的投影设备的数量为9，并将它们分别名为：ASU_1、ASU_2、ASU_3、···、ASU_9，且所确定的9个投影设备中不包括主腕投设备自身；
相应地，主腕投设备根据所确定的投影设备的数量及名称，将图5所显示的一幅待拼接的全景图像分割成图6所示的9幅子图像，并分别命名为：1-ASU_1、2-ASU_2、3-ASU_3、···和9-ASU_9，然后对每一子图像的分辨率任意进行调整，获得如图7所示的调整后的子图像；
然后，主腕投设备将调整后的9幅子图像按1-ASU_1至9-ASU_9的顺序，对应分享给名为：ASU_1、ASU_2、ASU_3、···和ASU_9的其他腕投设备，所确定的9个腕投设备分别根据接收到的子图像的分辨率，对自身到投影屏幕的距离调整，在子图像间能够无缝拼接时，将对应子图像投影至投影屏幕即可拼接出图6所示的一幅全景图像。
需要说明的是，在图4、图6和图7中，每一子图像外围灰色的方框代表投影屏幕，实际投影屏幕没有颜色，投影后投影屏幕上呈现出来的只有图像本身。
本发明实施例提供的一种图像拼接方法，可以确定用于进行图像拼接的可穿戴式投影设备；根据所确定的投影设备的数量，将自身存储的待拼接图像分割成所述数量个子图像；将所述数量个子图像对应分享至所确定的各个投影设备，以使所确定的投影设备分别对各个子 图像进行投影，进而拼接出所述待拼接图像。因此，应用本发明提供的方法，能够通过拼接的方式将一幅大型的全景图像完整的投影出来，满足了用户同时观看一幅大型的全景图像的全部内容的需求，提升了用户体验效果。且，相比于传统的投影设备，可穿戴式投影设备体积小巧，便于携带，其投影位置可以被灵活设置，更能满足用户随时随地同时观看一幅大型的全景图像的全部内容的需求。
相应于上述方法实施例，如图8所示，本发明实施例还提供了一种图像拼接装置，该装置包括：
确定模块801，用于确定用于进行图像拼接的可穿戴式投影设备；
由于本发明是利用多台腕投设备拼接出一幅全景图像，因此，在拼接前，可以将存储有待拼接图像的腕投设备作为主腕投设备，并将主腕投设备作为本装置的实施主体。
主腕投设备可以首先与其他腕投设备建立通信连接，连接后，确定参与图像拼接的腕投设备的数量，需要注意的是，所确定的投影设备中可以包括主腕投设备自身，也可以不包括。
图像分割模块802，用于根据所确定的投影设备的数量，将自身存储的待拼接图像分割成所述数量个子图像，其中，所述数量不小于2；
所确定的投影设备的数量即为参与投影的投影设备的数量。
在本发明提供的实施例中，可以将该数量用N表示，N为整数，且N≥2。
主腕投设备可以利用图像处理软件对自身存储的待拼接图像分割成N张子图像，分割后的子图像可以为任意形状。
分享模块803，用于将所述数量个子图像对应分享至所确定的各个投影设备，以使所确定的投影设备分别对各个子图像进行投影，进而拼接出所述待拼接图像。
需要说明的是，分享模块803中“分享”的对象可以是主腕投设备自身，也可以是不包括主腕投设备自身的其他参与投影的投影设备。
当分享的对象不是主腕投设备自身而是其他投影设备时，主腕投设备可以通过主动发送的方式将子图像分享给所确定的各腕投设备，也可以是其他腕投设备主动从主腕投设备上获取子图像以达到分享的目的。
当所确定的投影设备中不包括主腕投设备本身时，将N个子图像对应分享给N个其他投影设备，以使N个其他投影设备分别将各个子图像投影至投影屏幕上，进而拼接出所述待拼接图像；
当所确定的投影设备中包括主腕投设备本身时，将N张子图像中的N-1张子图像对应 分享给N-1个其他投影设备，将剩余的一张子图像保留在主腕投设备上，以使主腕投设备与N-1个其他腕投设备一起将相应子图像的投影至投影屏幕上，以拼接出待拼接图像。
图8所示的这种图像拼接装置，可以通过拼接的方式将一幅大型的全景图像完整的投影出来，满足了用户同时观看一幅大型的全景图像的全部内容的需求，提升了用户体验效果。且，相比于传统的投影设备，可穿戴式投影设备体积小巧，便于携带，其投影位置可以被灵活设置，更能满足用户随时随地同时观看一幅大型的全景图像的全部内容的需求。
由于腕投设备投影出的子图像的尺寸大小与该腕投设备距投影屏幕的距离有关，且很多情况下，各腕投设备的穿戴者所在的位置是不同的，从而使得所确定的各腕投设备与投影屏幕的距离也是不同的。
因此，为了使各投影设备投影后的子图像能够无缝拼接，优选的，在图8所示的实施例的基础上，所示装置还包括：调整模块，用于在所述将所述数量个子图像对应分享至所确定的各个投影设备前，调整所述数量个子图像中至少一个子图像的分辨率。
具体的，可以根据所确定的各腕投设备与投影屏幕的距离，对相应的子图像的分辨率进行调整，使得接收到相应子图像的各投影设备，在不调整自身与投影屏幕的距离的前提下，通过投影拼接出待拼接图像。
或者，所述调整模块，用于在所述将所述数量个子图像对应分享至所确定的各个投影设备前，调整所述数量个子图像中至少一个子图像的分辨率。
具体的，可以对所述数量个子图像中至少一个子图像的分辨率进行任意地调整，使得接收到相应子图像的各腕投设备根据该子图像的分辨率，对自身与投影屏幕的距离进行调整后，再投影出相应的子图像，以拼接出待拼接图像。
上述通过调整子图像的分辨率，以使所确定的各腕投设备根据接收到的子图像的分辨率调整自身与投影屏幕的投影距离的方案，在满足用户同时观看一幅大型的全景图像的全部内容的需求前提下，可以增加所确定的各腕投设备投影时所在的位置的灵活性，使得腕投设备穿戴者可以随时随地进行投影，使得图像拼接更为方便。
另外，同样需要说明的是，本发明实施例提供的图像拼接装置，也可以用于游戏，以丰富人们的业余生活。
如图9所示，本发明实施例提供了另一种图像拼接装置，该装置除了包括：确定模块801、图像分割模块802和分享模块803外；还包括：子图像名称确定模块901；
子图像名称确定模块901，用于在所述将所述数量个子图像对应分享至所确定的各个投影设备前，根据所确定投影设备的名称，对所述数量个子图像分别进行命名；
具体的，可以首先对所确定的每一投影设备进行命名，例如，将所确定的各投影设备分别命名为：ASU_1、ASU_2、ASU_3、···、ASU_N；然后将分割获得的N张子图像分别命名为：1、2、3、···、N。
此时，分享模块803，具体用于将所述数量个子图像分享至与该子图像名称匹配的所确定的投影设备。
具体的，主腕投设备可以将N张子图像分享至名称相互对应的各投影设备。例如，将名为“1”的子图像对应分享给名为“ASU_1”的投影设备，将名为“2”的子图像对应分享给名为“ASU_2”的投影设备，以此类推，直至将N张子图像全部分享至对应的投影设备。
需要说明的是，当所确定的投影设备中包括主腕投设备时，对主腕投设备依照同样的方法进行命名，并将与主腕投设备名称相匹配的子图像保留在主腕投设备上，以使主腕投设备参与图像拼接。
图9所示的这种图像拼接装置，也可以通过拼接的方式将一幅大型的全景图像完整的投影出来，满足了用户同时观看一幅大型的全景图像的全部内容的需求，提升了用户体验效果。且，相比于传统的投影设备，可穿戴式投影设备体积小巧，便于携带，其投影位置可以被灵活设置，更能满足用户随时随地同时观看一幅大型的全景图像的全部内容的需求。
另外，图8或图9所示的图像拼接装置中的分享模块803，具体可以在监测到穿戴者的第一预设动作时，将所述数量个子图像对应分享至所确定的各个投影设备。
首先，当主腕投设备监测到穿戴者抬起手臂的动作时，再次激活与其他腕投设备的通信连接。然后，在监测到穿戴者的第一预设动作时，将所述数量个子图像对应分享至所确定的各个投影设备。
具体的，当可穿戴式投影设备为腕投设备时，第一预设动作可以为穿戴者的晃动手臂的动作；当可穿戴式投影设备为眼镜时，第一预设动作可以为穿戴者的眨眼动作。
相应地，上述任一实施例提供的图像拼接装置，还可以包括：接收模块，用于接收所确定的投影设备在监测到穿戴者的第二预设动作后发送的图像分享成功确认消息，以使主腕投设备知晓子图像的分享是否成功。
具体的，接收子图像的腕投设备穿戴者也可以通过抬起手臂的动作激活与主腕投设备的通信连接，并通过晃动手臂的动作确认接收相应的子图像。这时，晃动手臂的动作即为第二预设动作。
这种通过监测穿戴者的动作进行通信连接、子图像发送和子图像接收的方式，不仅不需要穿戴者按动投影设备上的操作按钮，使得图像拼接的操作更为简单易行，还提升了穿戴者 进行图像拼接时的趣味性。
本发明实施例提供的一种图像拼接装置，可以确定用于进行图像拼接的可穿戴式投影设备；根据所确定的投影设备的数量，将自身存储的待拼接图像分割成所述数量个子图像；将所述数量个子图像对应分享至所确定的各个投影设备，以使所确定的投影设备分别对各个子图像进行投影，进而拼接出所述待拼接图像。因此，应用本发明提供的装置，能够通过拼接的方式将一幅大型的全景图像完整的投影出来，满足了用户同时观看一幅大型的全景图像的全部内容的需求，提升了用户体验效果。且，相比于传统的投影设备，可穿戴式投影设备体积小巧，便于携带，其投影位置可以被灵活设置，更能满足用户随时随地同时观看一幅大型的全景图像的全部内容的需求。
