图1为本发明实施例提供的一种立体图形的标注方法的步骤流程图，本实施例可适用于立体几何顶点标注的情况，该方法可以由立体图形的标注装置来执行，该装置可以通过软件和/或硬件的方式来实现，并集成在执行本方法的设备中，如图1所示，该方法可以包括如下步骤：
步骤110、显示立体图形。
本实施例中，立体图形可以是指智能交互设备显示的三维立体图形，该三维立体图形也可以称为立体几何图形或立体几何，如可以是在显示屏幕上展示的立方体、长方体等。
在实现中，智能交互设备可以通过诸如白板等软件，在操作界面上显示立体图形，使得用户可以在该操作界面上对该立体图形进行各种操作，如修改立体图形的形状、移动立体图形的位置等。其中，操作界面可以是指可以进行各种用户操作的界面，如用户可以在操作界面上进行图形绘制、图形编辑、图形显示、图形顶点标注等操作。
步骤120、确定所述立体图形的目标标注顶点，并在所述目标标注顶点对应的标记框中显示光标，其中，所述标记框的显示位置为依据所述目标标注顶点的棱线夹角确定。
本发明实施例在需要对立体图形的顶点进行标注时，可以根据标注触发指令确定出该立体图形当前所需要标注的顶点，以作为目标标注顶点；随后，可根据该目标标注顶点关联棱线确定出棱线夹角，以根据该棱线夹角确定出该目标标注点对应标记框的显示位置，进而可基于该显示位置在操作界面上展示标记框，以及在该标记框里显示光标，使得用户可以在该标记框中输入信息对目 标标注顶点进行标注，避免用户针对需要标注的顶点手段拖放标记框的麻烦，即解决了相关技术中需要用户为立体图形待标注顶点逐一拖放标记框所导致的操作繁琐问题，提供顶点标注效率。
其中，标注触发指令可以用于启动顶点标注功能，使得智能交互设备或该智能交互设备中的软件可在基于该顶点标注功能进行顶点标注。在一些实施例中，本发明实施例在确定立体图形的目标标注顶点之前，还可以包括：接收标注触发指令。该标注触发指令可以是用户直接在操作界面上提交的，也可以是根据用户提交的顶点标注触发擦操作生成的，如可以在用户点击软件上的顶点标注按钮后自动生成标注触发指令，使得智能交互设备可以接收到该标注触发指令。当然，该标注触发指令也可以是有软件或智能交互设备根据顶点标注需求自动生成的。
步骤130、当接收到输入信息时，在所述标记框中显示所述输入信息，所述输入信息用于对所述目标标注顶点进行标注。
本发明实施例中，在目标标注顶点对应的标记框显示后，用户可以针对目标标注顶点在该标记框中输入信息，使得智能交互设备或该智能交互设备中的软件可以接收到该输入信息，并在目标标注顶点对应的标记框中显示该输入信息，以采用该输入信息对目标标注顶点进行标注，达到标注顶点标注的目的。
综上，本发明实施例在显示立体图形后，可确定该立体图形的目标标注顶点，并在该目标标注顶点对应的标记框显示光标，使得用户可以在该标记框输入信息对目标标注顶点进行标注，且目标标注顶点对应标记框的显示位置为依据目标标注顶点的棱线夹角确定，无需用户为待标注的顶点手动拖放标记框，即简化顶点标注操作，提高顶点标注效率。
需要说明的是，本发明实施例中的标记框又称标注框，可以用于对顶点进行标注，且该标记框与其所标注的顶点关联，其可以是操作界面的一个“文本框”、“编辑框”等。
在实现中，本发明实施在检测到标注触发指令后，可以基于该标注触发指令启动顶点标注功能，并可基于标注触发指令确定当前显示的立体图形各顶点的标注位置，以作为各顶点对应标记框的显示位置，进而可以分别按照各顶点的标注位置显示各顶点的标记框，使得用户可以在各顶点的标记框输入信息进行顶点标注，满足用户的顶点标注需求。在一些实施例中，上述确定所述立体图形的目标标注顶点，可以包括：基于所述标注触发指令确定立体图形各顶点 的标注位置；分别按照所述各顶点的标注位置显示各顶点的标记框，并基于显示的标记框确定出第一标记框，以将所述第一标记框对应的顶点确定为所述目标标注顶点。其中，第一标记框可以是指当前所需要标注的第一个顶点的标记框，如在具有两个或多个待标注的顶点的情况下，可以将当前所需要标注的第一个顶点确定为目标标注顶点，并可将该目标标注顶点对应的标记框确定为第一标记框，以通过该第一标记框对目标标注顶点进行标注。
参照图2，示出了本申请可选实施中的一种立体图形的标注方法的步骤流程图，可以包括如下步骤：
步骤210、显示立体图形。
步骤220、接收标注触发指令，所述标注触发指令用于启动顶点标注功能。
例如，在智能交互设备通过白板软件显示立体图形后，用户可以通过点击该白板软件上的按钮或者快捷键方式，向智能交互设备提交标注触发指令，使得智能交互设备依据该标注触发指令启动白板软件的顶点标注功能，进入顶点标注状态。
步骤230、基于所述标注触发指令确定立体图形各顶点的标注位置。
本发明实施例在启动顶点标注功能后，可以进入顶点标注状态，并可基于接收到的标注触发指令自动确定出立体图形各个顶点的标注位置，以分别按照各个顶点的标注位置显示各顶点的标记框，即执行步骤240。
在一种可选实施方式中，本发明实施例基于标注触发指令确定立体图形各顶点的标注位置，可以包括：确定立体图形每个顶点对应的棱线投影信息；依据每个顶点对应的棱线投影信息确定每个顶点的棱线夹角；依据每个顶点的棱线夹角确定每个顶点的标注位置。其中，棱线投影信息可以用于确定顶点的棱线夹角大小，可以包括顶点的两条或两条以上棱线对应的投影信息。
本发明实施例在进入顶点标注状态后，可以找到立体图形的每个顶点关联的棱线，并可通过三维投影算法计算出其在二维平面上的方向，如图3所示，在投影矩阵M(即图3中的立体图形)的顶点P0的三条棱线的投影分别为v1，v2，v3的情况下，可以通过两个顶点的投影坐标相减的方法，确定出出顶点P0的三条棱线对应的投影信息；该投影信息可以是向量信息，可以用于表征棱线的方向。随后，可根据向量点积公式，采用棱线投影信息可以计算出两个向量之间的夹角大小，即确定出每两条棱线之间的棱线夹角，然后可在确定出棱线夹角的角平分线上自动设置顶点的标注位置，以作为顶点对应标记框的显示位 置，进而可按照该显示位置显示顶点对应的标记框，无需用户手动拖放标记框。
本发明实施例可以从确定出的棱线夹角中选择夹角最大的棱线夹角作为目标棱线夹角，以在目标棱线夹角的角平分线上设置顶点的标记框的显示位置，从而能够避免标记框遮挡立体图形的棱线或顶点。可选的，上述依据每个顶点的棱线夹角确定每个顶点的标注位置，可以包括：针对每个顶点，从所述顶点的棱线夹角中选取目标棱线夹角；确定所述目标棱线夹角对应的角平分线信息；基于所述角平分线信息，在所述目标棱线夹角的角平分线上确定所述顶点的标注位置。
例如，从三维到二维存在一个投影矩阵，在确定顶点P0(x,y,z)后，可以获取该顶点P0(x,y,z)的投影坐标信息，记录为P’＝P0*M；随后可通过两个顶点的投影坐标信息相减，即可得到棱线的方向，如结合上述例子，可将顶点P0关联的第一条棱线记录为向量v1，将顶点P0关联的第二条棱线记录为向量v2，以及将顶点P0关联的第三条棱线记录为向量v3；随后可根据向量点积公式可以计算出每两个向量之间的夹角，并选择计算出的最大夹角作为该顶点P0的目标棱线夹角，如可以按照逆时针顺次计算各棱线投影间的夹角，即计算出v1v2、v2v3、v3v1各自构成夹角，其中v1v2之间的夹角最大，进而可以将v1v2之间的夹角确定为目标棱线夹角，随后可以根据向量v1和向量v2计算出最大夹角的角平分线，即确定目标棱线夹角对应的角平分线信息，以基于角平分线信息在目标棱线夹角的角平分线上确定顶点P0的标注位置，如图3所示，可以在最大夹角的角平分线上以固定的R值来设定标记框的中心，然后以此中心来放置固定大小的标记框，并显示在操作界面上，使得用户可以在标记框中输入信息对顶点P0进行标注。
步骤240、分别按照所述各顶点的标注位置显示各顶点的标记框，并基于显示的标记框确定出第一标记框，以将所述第一标记框对应的顶点确定为目标标注顶点。
当进入顶点标注状态时，本实施例可以基于该标注触发指令自动确定出立体图形各个顶点的标注位置，以分别按照各个顶点的标注位置显示各顶点的标记框。如图3所示，白板软件可以会自动在立体几何(即立体图形)的各个顶点处显示标记框；并可从显示的标记框中选取其中任意一个标记框作为第一标记框，以该将第一标记框对应的顶点确定为目标标注顶点，如将输入光标定位在首个显示的标记框中，以将首个显示的标记框确定为第一标记框，使得用户 可以在该第一标记框输入信息对目标标注顶点进行标注。
步骤250、当接收到输入信息时，在目标标注顶点对应的标记框中显示所述输入信息，所述输入信息用于对所述目标标注顶点进行标注。
本发明实施例在目标标注顶点对应的标记框为第一标记框时，在用户输入信息后，可以在第一标记框显示输入信息，以采用该输入信息对目标标注顶点进行标注，满足用户的顶点标注需求。
需要说明的是，本实施例中的第一标记框也可以是非首个显示的标记框，如可以是按照标记框显示顺序，选择第二个显示或最后一个显示的标记框作为第一标记框；也可以按照其他方式选择第一标记框，如可以基于光标位置来确定出第一标记框等。
此外，用户可以通过提交标注切换指令，来修改当前所需标注的目标标注顶点。本发明实施例在所述目标标注顶点对应的标记框中显示光标之后，还可以包括：接收标注顶点切换指令；依据所述标注顶点切换指令，将所述光标移动至所述立体图形的第二标记框，并将所述目标标注顶点更换为所述第二标记框对应的顶点。其中，标注顶点切换指令可以用于切换光标所在的标记框，以修改当前所需标注的目标标注顶点，且该标注顶点切换指令可以由用户操作所触发的，如可以是基于用户提交的键盘操作或鼠标操作或触摸操作生成的等。例如，用户操作可以是点击键盘的Tab键的操作。
本实施例中，用户可以通过点击智能交互设备上显示的按钮或键盘快捷键等方式，向交互智能平板提交标注触发指令，使得智能交互设备进入顶点标注状态。例如，用户可以通过点击智能交互设备显示的“顶点标注”按钮，向标注触发指令，以触发智能交互设备生成进入顶点标注状态。当然，用户也可以通过其他方式触发智能交互设备进入顶点标注状态，如可通过点击键盘中诸如“Ctrl+M”键等预设快捷键来快速进入顶点标注状态等。
当进入顶点标注状态时，可以自动在立体几何的各个顶点的标注位置显示标记框，如图4所示，并且可以将输入光标定位在首个标记框中，即可以将第一个显示的标记框确定为目标标注顶点对应的标记框，并在该目标标注顶点对应的标记框中显示光标。
在本实施例中，用户可向智能交互设备输入标注顶点切换指令，以触发智能交互设备依据该标注顶点切换指令将光标移动至另一顶点的标记框，以将目标标注顶点切换至另一顶点，即将光标移动至立体图形的第二标记框和将目标 标注顶点更换为该第二标记框对应的顶点。例如，用户可以通过按下“TAB”键来向智能交互设备提交标注顶点切换指令，从而切换输入光标所在的标记框，如图4所述，将光标从第一标记框移动到第二标记框，以将目标标注顶点切换至另一个顶点。
在本申请一个可选实施例中，在进入标注顶点标记状态时，可以不自动显示立体图形顶点的标记框，而在鼠标移动到某个顶点附近时显示该顶点对应的标记框，以将该顶点确定为目标标注顶点，并可将输入光标定位在该目标标注顶点对应的标记框，以将该目标标注顶点对应的标记框确定为第一标记框，使得用户可以在该第一标记框输入信息对目标标注顶点进行标注。可选的，上述确定所述立体图形的目标标注顶点，包括：在接收到标注触发指令后，监测光标位置；当所述光标位置与所述立体图形中任一顶点位置的间距小于预设间距时，将所述顶点位置对应的顶点确定为所述立体图形的目标标注顶点。
在实现中，本发明实施例在接收到顶点触发指令后，可以根据标注触发指令进入顶点标注状态，以在该顶点标注状态下检测监测光标位置。其中，光标位置可以是指输入光标的显示位置，且该光标位置可以根触摸操作或鼠标操作来确定。随后，可以将监测到的光标位置与当前显示的立体图形各顶点位置进行比较，以确定光标位置与该立体图形的各顶点位置之间的间距。若光标位置与立体图形中一顶点位置的间距小于预设间距，则可将该顶点位置对应的顶点确定为目标标注顶点，随后可以确定与该目标标注顶点关联的至少两条棱线，以根据棱线之间的棱线夹角确定出该目标标注顶点的标注位置，从而可以按照该目标标注顶点的标注位置显示该目标标注顶点对应的标记框中，同时可以将光标定位至该目标标注顶点对应的标记框中并显示，以提示用户在该标记框输入信息对目标标注顶点进行标注，无需用户为待标注的顶点手动拖放“文本框”作为标记框，即简化用户操作，提高顶点标注效率。
本实施例在目标标注顶点对应的标记框中显示光标之前，还可以包括：确定所述目标标注顶点对应的棱线投影信息，其中，所述棱线投影信息用于确定所述目标标注顶点的至少两个棱线夹角；从所述至少两个棱线夹角中选取目标棱线夹角；确定所述目标棱线夹角对应的角平分线信息，所述角平分线信息用于在目标棱线夹角的角平分线上确定标注位置；显示所述标记框，所述标记框为按照所述标注位置进行显示的。
本发明实施例在确定出目标标注顶点时，可以根据与该目标标注顶点相邻 的其他顶点对应的坐标信息，确定出该目标标注顶点对应的棱线投影信息，随后可基于该目标标注顶点对应的棱线投影信息确定出目标标注顶点的一个或多个棱线夹角，并可根据确定出的棱线夹角的大小选取出夹角最大的目标棱线夹角，以根据该目标棱线夹角的角平分线信息在该目标棱线夹角的角平分线上确定标注位置，从而可以在该标注位置上显示该目标标注顶点对应的标记框。
作为本申请的一个示例，交互智能平板进入顶点标记状态时，可以不自动显示立体图形顶点对应的标记框，在鼠标移动到某个定顶点附近时，高亮此顶点，并可在该顶点的标注位置显示一个标记框，如图5所示。此时，若用户点击鼠标左键，即可为该顶点添加一个标记框。在添加“标记框”后，输入光标可以自动定位在该标记框内部，使得用户可以在该标记框中输入标识字母，即输入信息对目标标注顶点进行标注。当用户在标记框外部点击鼠标，交互智能平板即可确认用户完成输入，将用户的输入信息与目标标注顶点进行关联，以完成对该目标标注顶点的标注并退出该目标标注顶点的标记状态。当用户在其它顶点附近移动鼠标时，交互智能平板可以重复执行如上操作，即可对其它顶点进行标注。
本发明实施例在立体图形发生改变时，如图6所示，在立体图形旋转时，可以根据立体图形的变化来自动调整顶点对应标记框的显示位置，即能够自动调整顶点的标注位置，避免用户在立体图形变化后手动调整标记框位置的麻烦，简化用户操作。可选的，本实施例还可以包括：当检测到立体图形变化，隐藏所述立体图形的顶点的标记框；当检测到立体图形变化结束时，对所述立体图形变化后顶点的标注位置进行更新，并按照依据更新后的标注位置显示所述顶点对应的标记框。
在实现中，当立体图形的位置或者其三维尺寸、旋转角度发生变化，本实施例可以在开始变化时自动隐藏所有顶点的标记框，而在变化结束时自动显示所有顶点的标记框，并且可以自动调整标记框的位置，以防标记框被变化后的棱线遮挡。其中，标记框的位置的自动调整可依据预设的标记框默认位置算法来计算。
例如，在立体图形变化过程中，可在白板软件的程序中设置标记框的“可见性”为“false”，使得该白板软件在立体图形变化过程中隐藏顶点对应的标记框，即不会呈现标记框，达到隐藏的效果；而在变化结束后，重新计算各个顶点的棱线投影信息，以通过顶点棱线的投影夹角来重新确定标记框的位置，以按照 重新确定的标记框的位置显示顶点对应的标记框，达到自动调整顶点标注位置的目的，无需用户手动调整顶点标注位置，简化用户操作，以及提高立体图形变化后顶点标注效率。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明实施例并不受所描述的动作顺序的限制，因为依据本发明实施例，某些步骤可以采用其他顺序或者同时进行。
