Description

教学关联信息的确定方法、装置、教学设备及存储介质 技术领域
本发明涉及电子教学技术领域，尤其涉及教学关联信息的确定方法、装置、教学设备及存储介质。
背景技术
在电子教育设备改善课室教学环境的大潮中，通过演示文稿课件进行教学授课已是常用的教学方式之一。基于该种方式教学时，教学者需要预先编辑所需的演示文稿课件，但预先编辑的演示文稿课件很难含盖所有教学信息，因此在实际教学中，教学者基于演示文稿课件授课的同时仍需要在书写板上进行一定的教学板书，来展示演示文稿课件无法体现的内容。
然而，听讲者在上述授课方式下，仍需要对教学者的板书内容进行记录，且在课后复习时，还需要将记录的板书内容与演示文稿课件相结合作为完整的教学信息进行参考学习。上述听讲者对教学板书的记录在一定程度上影响了听讲者的课堂效率，同时也给听讲者的课后复习带来了不便。
发明内容

下面结合附图和实施例对本发明作进一步的详细说明。可以理解的是，此处所描述的具体实施例仅仅用于解释本发明，而非对本发明的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本发明相关的部分而非全部结构。
实施例一
图1为本发明实施例一提供的一种教学关联信息的确定方法的流程示意图，该方法适用于将教学板书内容与教学演示文稿内容进行实时关联的情况，该方法可以由教学关联信息的确定装置执行，其中该装置可由软件和/或硬件实现，并一般集成在教学设备上。
可以理解的是，所述教学设备具体可指具有教学板书功能和教学信息显示功能的设备，可以是书写板与显示终端结合后形成的电子设备。
需要说明的是，本实施例所提供方法的应用背景可以是：教学过程中，教学者以及演示文稿课件为主进行多媒体教学，同时通过教学板书对演示文稿课件中的主要内容进行板书讲解。在实际应用中，仅能向听讲者提供演示文稿课件的教学信息，无法提供教学板书内容，更无法将演示文稿课件与教学板书内容关联后提供给听讲者。基于本实施例的教学关联信息的确定方法，可以在教学者的教学过程中实时的将演示文稿与教学板书内容进行关联，由此向听讲者提供可直接参考的教学关联信息。
如图1所示，本发明实施例一提供的一种教学关联信息的确定方法，包括如下操作：
S101、监测到上一演示文稿页跳转到当前演示文稿页后，实时捕获教学板 书图像并缓存至设定图像列表。
具体地，所述上一演示文稿页及当前演示文稿页具体可指教学所需的演示文稿课件中的演示文稿内容，所述当前演示文稿页具体可理解为当前显示在教学设备的显示终端上的教学文稿；所述上一演示文稿页对应于当前演示文稿而言，具体相当于在当前演示文稿之前在显示终端上显示的教学文稿。
在本实施例中，所述教学板书图像具体可理解为包含书写板上教学板书内容的图像，具体可由预先设置的图像采集装置(如摄像头)捕获；所述设定图像列表具体可以理解为一个预先设定的信息存储表，并一般将该设定图像列表为空，可用来存储所捕获的教学板书图像。
本步骤相当于设定了教学板书图像的捕获条件，即，在监测到教学设备显示终端上显示的演示文稿课件由上一演示文稿页跳转到当前演示文稿页后，开始进行新一轮的图像捕获，由此实时捕获教学设备书写板上教学者板书的教学内容。本步骤将实时捕获的教学板书内容缓存至所述设定图像列表。
S102、接收到所述当前演示文稿页到下一演示文稿页的跳转指令时，对所述设定图像列表中的教学板书图像进行拼接处理，形成板书汇总图像。
在本实施例中，所述下一演示文稿页同样对应于当前演示文稿页而言，具体相当于在当前演示文稿之后即将在显示终端上显示的教学文稿。所述跳转指令可以由教学者在讲解完当前演示文稿页中的内容后触发生成的指令，所述跳转指令具体可用于控制当前演示文稿页到下一演示文稿页的跳转，同样，也可用于上一演示文稿页到当前演示文稿页的跳转。
本实施例具体可相当于在接收到所述跳转指令后，执行演示文稿页的跳转操作前，实现教学板书内容到当前演示文稿页的关联，由此实现当前演示文稿 页所对应当前教学关联信息的确定。
具体地，本步骤在接收到所述跳转指令时，实现对设定图像列表中所缓存教学板书图像的拼接操作，以获得关联所需的板书汇总图像。所述板书汇总图像具体包含了教学设备显示终端上进行当前演示文稿页显示的时间段内，书写板上存在的所有教学板书内容。本实施可将所述板书汇总图像包含的图像内容确定为与当前演示文稿页存在关联的教学板书内容。
同时可以理解的是，本步骤在执行教学板书图像的拼接处理之前，默认停止了教学板书图像的捕获，且可认为再次符合S101的条件时才重新进行教学板书图像的捕获操作。
S103、将所述板书汇总图像***新创建的空白演示文稿页，形成所述当前演示文稿页的当前教学关联信息。
本步骤接上述S102，具体用于在获得当前演示文稿页关联的板书汇总图像后，将板书汇总图像作为演示文稿课件的一部分添加至演示文稿课件中，所添加的包含板书汇总图像的教学信息实际相当于当前演示文稿页的教学关联信息。
具体地，所述空白演示文稿页相当于可进行演示文稿内容编辑的空白页，本实施可在组成演示文稿课件的任意演示文稿页之前或之后添加新创建的空白演示文稿页。为保证教学者预先编辑演示文稿页的显示顺序不受影响，本实施例优选在当前演示文稿页之前选定空白演示文稿页的创建位置。
可以理解的是，本实施例可在完成上述S102及S103的操作后，根据跳转指令实现当前演示文稿页到下一演示文稿页的跳转。后续则相当于再次返回S101实现对下一演示文稿页所关联教学板书内容的确定操作。
本发明实施例一提供的一种教学关联信息的确定方法，首先监测到上一演示文稿页跳转到当前演示文稿页后，实时捕获教学板书图像并缓存至设定图像列表；然后接收到所述当前演示文稿页到下一演示文稿页的跳转指令时，对所述设定图像列表中的教学板书图像进行拼接处理，形成板书汇总图像；最终将所述板书汇总图像***新创建的空白演示文稿页，形成所述当前演示文稿页的当前教学关联信息。利用该方法，能够在基于演示文稿的教学过程中，实时生成各演示文稿页对应的教学板书关联信息，由此避免了听讲者在听课阶段对教学者所板书教学内容的记录，同时演示文稿课件与教学板书内容的实时关联，也方便了听讲者课后复习时的教学信息查阅。
实施例二
图2a为本发明实施例二提供的一种教学关联信息的确定方法的流程示意图。本发明实施例以上述实施例为基础进行优化，在本实施例中，首先将对所述设定图像列表中的教学板书图像进行拼接处理，进一步优化为：提取并分析所述设定图像列表中各教学板书图像的教学板书内容；滤除重复出现的教学板书内容后，以时间顺序对余下的教学板书内容进行排列拼接，形成板书汇总图像。
本实施例还进一步将所述板书汇总图像***新创建的空白演示文稿页，形成所述当前演示文稿页的当前教学关联信息，具体优化为：在所述上一演示文稿页与所述当前演示文稿页之间，创建空白演示文稿页；在所述空白演示文稿页中以***文件图像的形式***所述板书汇总图像，构成关联演示文稿页；将所述关联演示文稿页确定为所述当前演示文稿页的当前教学关联信息。
进一步地，本实施例在对所述设定图像列表中的教学板书图像进行拼接处理之前，还优化增加了：根据设定的障碍遮挡判定条件，确定所述设定图像列表中包含障碍遮挡的教学板书图像并删除。
在上述优化的基础上，本实施例在将所述板书汇总图像***新创建的空白演示文稿页之前，还优化增加了：将所述板书汇总图像与所述上一演示文稿页对应的上一教学关联信息进行比对；删除所述板书汇总图像中属于所述上一教学关联信息的教学板书内容，形成新的板书汇总图像。
此外，本实施例在形成所述当前演示文稿页的当前教学关联信息之后，还具体包括了：清空所述设定图像列表中缓存的教学板书图像。
如图2a所示，本发明实施例二提供的一种教学关联信息的确定方法，具体包括如下操作：
S201、监测到上一演示文稿页跳转到当前演示文稿页后，实时捕获教学板书图像并缓存至设定图像列表。
示例性地，可以在达到本步骤设定的上一演示文稿页跳转到当前演示文稿页的条件时，开始进行实时捕获教学板书图像的操作，并可将捕获的教学板书图像缓存至设定图像列表。
S202、根据设定的障碍遮挡判定条件，确定所述设定图像列表中包含障碍遮挡的教学板书图像并删除。
本步骤相当于对设定图像列表中教学板书图像的预筛选操作，可以有效筛选出存在障碍遮挡的教学板书图像并进行删除，从而保证后续板书汇总图像确定的有效性。所述障碍遮挡具体可理解为对教学板书图像中教学板书内容进行的信息遮挡，一般情况下，通常是教学者的手部遮挡。
具体地，所述障碍遮挡判定条件可以是：教学板书图像是否包含除书写板背景及书写笔迹之外的其他色彩特征；若是，则进一步判断其他色彩特征在教学板书图想象中形成的图像区域是否属于设定的覆盖面积范围；如果是，则可认为教学板书图像存在障碍遮挡。
本步骤可基于上述障碍遮挡判定条件，对设定图像列表中的每一张教学板书图像进行判定，以确定教学板书图像是否存在障碍遮挡，并删除存在障碍遮挡的教学板书图像。可以理解的是，本步骤的操作可以在实时捕获教学板书图像的过程中进行，即，可以每次都对最新缓存至设定图像列表中的教学板书图像进行障碍遮挡判定。
S203、接收到所述当前演示文稿页到下一演示文稿页的跳转指令时，提取并分析所述设定图像列表中各教学板书图像的教学板书内容。
可以理解的是，本实施例可将接收到所述当前演示文稿页到下一演示文稿页的跳转指令作为教学关联信息确定的触发条件，由此在执行当前演示文稿页跳转到下一演示文稿页的跳转操作之前，根据当前演示文稿页显示时间内捕获的教学板书图像，确定与当前演示文稿页相关联的教学板书内容。
具体地，本步骤可在满足教学关联信息的触发条件后，首先对设定图像列表中的各教学板书图像进行提取分析操作，进而提取各教学板书图像包含的教学板书内容。
示例性地，图2b～图2d分别给出了本发明实施例二所提供设定图像列表中缓存的教学板书图像。具体地，假设设定图像列表在当前演示文稿页显示时间内分别捕获了图2b、图2c以及图2d所示的教学板书图像，基于本步骤的操作，可以分别从图2b、图2c以及图2d所示的教学板书图像中提取出对应的教学板 书内容21。
需要说明的是，可认为图2c至图2d之间存在多张捕获的教学板书图像，但因教学板书图像中存在障碍遮挡，所以进行了删除，进而在设定图像列表中图2c之后保存了图2d。
S204、滤除重复出现的教学板书内容后，以时间顺序对余下的教学板书内容进行排列拼接，形成板书汇总图像。
在本实施例中，对于连续捕获的教学板书图像而言，所包含的教学板书内容可能存在重复的部分，本步骤可以将前后教学板书图像中的教学板书内容进行比对，由此滤除重复的教学板书内容，仅保留所重复教学板书内容的一份；之后，本步骤可以对余下的教学板书内容基于捕获时间进行排列拼接，最终形成所需的板书汇总图像。
示例性地，图2e为本发明实施例二拼接处理后获得的板书汇总图像。接上述示例，本步骤对图2b、图2c以及图2d中的教学板书内容21进行提取后，通过教学板书内容的比对，滤除重复的教学板书内容后，获得了图2e的板书汇总图像22中最终显示教学板书内容220。
S205、将所述板书汇总图像与所述上一演示文稿页对应的上一教学关联信息进行比对。
在本实施例中，基于S203和S204获得板书汇总图像后，还可以基于S205和S206进一步对板书汇总图像进行优化处理。具体地，可以将所获得板书汇总图像中的教学板书内容与上一演示文稿页相关联的上一教学关联信息进行比对。
本实施例可认为上一演示文稿页的上一教学关联信息同样基于本实施例提 供的教学关联信息的确定方法确定。所述上一教学关联信息具体相当于与上一演示文稿页关联的教学板书内容。
由于上一演示文稿页到当前演示文稿页的跳转时间很短，所以在捕获当前演示文稿页对应的教学板书图像时，教学板书图像中可能还包含了教学者对上一演示文稿页讲解时的教学板书内容，为确定教学关联信息的简洁性，本实施例在将板书汇总图像与当前演示文稿页进行关联前，首先对已在上一教学关联信息中出现的内容进行滤除。
S206、删除所述板书汇总图像中属于所述上一教学关联信息的教学板书内容，形成新的板书汇总图像。
具体地，通过S205的比对后，如果板书汇总图像中存在与上一教学关联信息相同的教学板书内容，则可进一步删除相同部分，并形成新的仅包含不重复教学板书内容的板书汇总图像由此也可保证板书汇总图像的大小能够适应演示文稿页。
可以理解的是，如果优化后的板书汇总图像的尺寸大小超出依旧超出在演示文稿页中正常显示时的尺寸，则可以对板书汇总图像进行图像分割，以形成多张子板书汇总图像来适应演示文稿页的显示尺寸。
本实施例下述S207至S209具体给出了板书汇总图像与当前演示文稿的关联过程。
S207、在所述上一演示文稿页与所述当前演示文稿页之间，创建空白演示文稿页。
在本实施例中，为体现板书汇总图像与当前演示文稿页之间的关联性，本步骤优选的将板书汇总图像与当前演示文稿页进行相邻设置，即，首先在上一 演示文稿页和当前演示文稿页之间，新创建一个空白演示文稿页。
S208、在所述空白演示文稿页中以***文件图像的形式***所述板书汇总图像，构成关联演示文稿页。
具体地，本步骤可以通过***文件图像的形式，自动将板书汇总图像***空白演示文稿页的正文编辑部分。需要说明的是，本实施例默认板书汇总图像保存在设定***存储路径下，且每次***时总选择最新存储时间对应的板书汇总图像。
可以理解的是，板书汇总图像的***空白演示文稿页时，具有自动调节大小以适应演示文稿页大小的功能。
此外，为明确所***板书汇总图像与当前演示文稿页的关联关系，本实施例进一步在空白演示文稿页的标题部分进行关联信息命名，由此形成包含关联信息名称及教学关联信息的关联演示文稿页。其中，本实施例可基于板书汇总图像的形成时间及当前演示文稿页的页码进行关联信息命名。
S209、将所述关联演示文稿页确定为所述当前演示文稿页的当前教学关联信息。
示例性地，图2f为本发明实施例二所提供原始演示文稿页的显示状态，图2g为本发明实施例二确定教学关联信息后的演示文稿页的显示状态。如图2f所示，具体给出了上一演示文稿页23与当前演示文稿页24，其中，当前演示文稿页的页码为2；接上述S204中的示例，图2g中将板书汇总图像22***在上一演示文稿页23和当前演示文稿页24之间，形成关联演示文稿页25，且可以发现，关联演示文稿页25中的关联信息命名为“10:20_2”，具体表示10:20形成的板书汇总图像与第2页演示文稿页关联。
S210、清空所述设定图像列表中缓存的教学板书图像。
在本实施例中，上述S201至S209具体给出了确定当前演示文稿页的教学关联信息的确定过程。对于整个演示文稿课件而言，需要为演示文稿课件中的每一演示文稿页都进行教学板书内容的关联，即，相当于循环执行S201至S209的操作。本实施例在循环执行上述操作前，需要执行S210的操作，以保证设定图像列表的初始状态一直为清空状态。
本发明实施例二提供的一种教学关联信息的确定方法，具体化了教学板书图像的拼接操作，还具体化了基于教学板书内容形成演示文稿的教学关联信息的过程；同时还优化增加了教学板书图像以及板书汇总图像的的筛选处理操作，并增加了设定图像列表的清空操作。利用该方法，能够更好的确定演示文稿关联的教学板书内容，并由此形成演示文稿的教学关联信息，由此避免了听讲者在听课阶段对教学者所板书教学内容的记录，同时演示文稿课件与教学板书内容的实时关联，也方便了听讲者课后复习时的教学信息查阅。

在本实施例中，该装置首先通过图像缓存模块31监测到上一演示文稿页跳转到当前演示文稿页后，实时捕获教学板书图像并缓存至设定图像列表；然后通过拼接处理模块32接收到所述当前演示文稿页到下一演示文稿页的跳转指令时，对所述设定图像列表中的教学板书图像进行拼接处理，形成板书汇总图像；值周通过关联确定模块33将所述板书汇总图像***新创建的空白演示文稿页，形成所述当前演示文稿页的当前教学关联信息。

进一步地，拼接处理模块32，具体可用于：

进一步的，该装置还优化包括了：
