本本申请实施例包括一种控制投影设备的方法，其中，该投影设备的控制方法应用于上述投影设备，动态投影设备可以是投影仪、投影机、动向投影仪、投影灯、互动投影设备等能实现动向投影方法的投影设备
请参阅图4-图5，图4和图5示出了根据本发明一个实施例的控制上述投影设备的方法流程图，该方法包括以下步骤：
步骤S101：控制所述驱动机构14所述图像采集装置13转动；
驱动机构14驱动所述图像采集装置13转动是指驱动机构14驱动所述图像采集装置13 360度转动，以使图像采集装置13可以采集投影设备四周的环境图像。
步骤S102:在所述图像采集装置13转动的过程中，获取所述图像采集装置13所拍摄的所述投影设备周边环境的环境图像；
环境图像是指投影设备所在位置周边图像，该环境图像用于构建投影设备所在位置的空间模型。
步骤S103:根据所述环境图像，识别所述投影设备周边的可投影墙体以及位于可投影墙体和投影设备之间的障碍物；
障碍物指的是位于投影单元15和可投影墙体之间，阻挡投影单元15所输出的投影光线，进而造成投影画面不完整的物体，在投影单元15投影时，需要避开障碍物，以保障投影画面完整性。
步骤S104:根据各所述可投影墙体以及各可投影墙体对应的障碍物，并且结合预设模型，确定最佳的可投影墙体；
可投影墙体是指位于投影设备周边，并且颜色为白色或者灰色等能够正常呈现画面的墙体。
在一些实施例中，如图5所示，步骤S104包括：
步骤S1041：确定各所述障碍物在对应可投影墙体上的投影位置；投影位置是指投影单元15的投影方向，障碍物投射到可投影墙体的位置。由于图像采集装置13的取景方向和投影单元15的投影方向是一致，因此，当存在障碍物时，障碍物会直接呈现在图像采集装置13所采集到 的图像中，因此，可以直接通过图像采集装置13所采集的图像进行识别。此处，由于投影单元15可以转动，当投影单元15所在的位置不相同，投影单元15的投射方向不一样，障碍物对投影单元15的投影光线影响不一样，因此，各障碍物的投影位置是选择在当投影单元15的投影光线与可投影墙体垂直时，障碍物在对应可投影墙体上的投影位置。
步骤S1042：确定各所述可投影墙体的中心点；
墙体通常是四方形，中心点是指可投影墙体对角线的交点。对于不规则的墙体，也可以通常补偿或者去掉边角的方式，构建四方形。
步骤S1043：根据各所述障碍物在对应的可投影墙体上的投影位置，以及，各所述可投影墙体的中心点，计算各所述可投影墙体中以对应的中心点为中心的空白中心区域，空白中心区域指的是未存在障碍物投影的区域。
空白中心区域也是四方形的，其长度和宽度的比例和投影单元15的投影画面的长度和宽度比例相同，换而言之，空白中心区域是以可投影墙体的中心点为中心，以投影单元15的投影画面的长度和宽度比例向外扩展，并且不存在障碍物的区域。
值得说明的是：在可投影墙体的中心区域进行投影，可以方便四周的观众观看，因此，根据可投影墙体的空白中心区域来选择最佳可投影墙体。
步骤S1044:根据所述空白中心区域，确定所述最佳的可投影墙体；
投影设备周边的可投影墙体的数量为多个，而每一个可投影墙体均可能存在空白中心区域，换而言之，空白中心区域的数量可能为多个，因此，可以根据空白中心区域再选择最佳的可投影墙体，在一些实施例中，步骤S1044具体包括：计算各所述可投影墙体的空白中心区域的面积，获取面积最大的所述空白中心区域；判断获取的空白中心区域的面积是否大于预设面积，若是，则获取所述空白中心区域的面积最大的可投影墙体为最佳的可投影墙体，若否，则输出不存在满足投影条件的可投影墙体的消息。
可以理解的是：除了将所述空白中心区域的面积最大的可投影墙体为最 佳的可投影墙体之外，在另一些实施例中，也可以位于投影设备所在空间的正中的空白中心区域对应的墙体为最佳可投影墙体，其中，投影设备所在空间的正中的空白中心区域是指垂直于空白中心区域的中心的直线经过投影设备所在空间的中心；又或者，以所在高度为预设高度的空白中心区域对应的墙体为最佳投影墙体，其中，预设高度为方便用户观看的高度，该预设高度的具体数据可以根据实验得到的。
在本本申请实施例中，投影设备20包括底座16、驱动机构14、投影单元15、图像采集装置13和显示装置12，通过控制所述驱动机构14驱动所述图像采集装置13转动，在图像采集装置13转运的过程中，获取所述图像采集装置13所拍摄的所述投影设备20周边环境的环境图像，然后根据所述环境图像，识别所述投影设备20周边的可投影墙体以及位于可投影墙体和投影设备20之间的障碍物；再根据各所述可投影墙体以及各可投影墙体对应的障碍物，并且结合预设模型，确定最佳的可投影墙体；最后控制所述显示装置12显示所述最佳的可投影墙体，实现投影设备20自动选择所在空间内的最佳投影墙体，无需要用户手动调整，非常方便。请参阅图6,图6是本发明控制投影设备20的方法第二实施例的流程图，该实施例与其它实施例不同之处在于，方法还包括：
步骤S105:控制所述驱动机构14，以驱动所述投影单元15正对最佳的可投影墙体的中心空白区域；
步骤S106：根据所述可投影墙体的中心空白区域的面积，调整所述投影单元15的焦距，以使所述投影单元15的投影图像位于最佳的可投影墙体的中心空白区域；
根据所述可投影墙体的中心空白区域的面积，调整投影单元15的焦距，以使投影单元15输出投影画面正好落在对应的中心空白区域中，避免投影画面过大，受到障碍物阻挡，影响投影画面的完整性，也可以避免投影画面过小影响用户的观看。
