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作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针对投影图像的触控方法及装置，应用于包括触摸板和显示屏的投影设备，其中，所述触摸板和所述显示屏的分辨率相同，该方案中，
根据所述触摸板的分辨率和所述显示屏的分辨率，针对所述显示屏所显示图像获得第一触控区域对应的第二触控区域，其中，所述第一触控区域为所述触摸板接收到的触控指令对应的触控区域；

根据所述第三触控区域和当前投影图像，解析所述触控指令；
根据解析结果，针对当前投影图像响应所述触控指令。
下面通过具体实施例，对本发明进行详细说明。
图1为本发明实施例提供的一种针对投影图像的触控方法的流程示意图，应用于包括触摸板和显示屏的投影设备，其中，所述触摸板和所述显示屏的分辨率相同，包括如下步骤：
步骤S101：根据所述触摸板的分辨率和所述显示屏的分辨率，针对所述显示屏所显示图像获得第一触控区域对应的第二触控区域。
其中，所述第一触控区域为所述触摸板接收到的触控指令对应的触控区域。
所述触控指令可以是用户在触摸板上进行点击、滑动等操作而生成的指令。需要说明的是，本申请只是以上述为例进行说明，实际应用中触控指令的具体生成方式并不仅限于此。
本领域内的技术人员可以理解的是，显示屏的分辨率简单的可以理解为：显示屏所能够显示图像的精密度，也就是指显示屏所能显示的像素的多少，可以用横向分量×纵向分量来表示，例如，显示屏分辨率为300×200，则该显示屏所能显示的像素为：宽度300个像素点、高度200个像素点。
本发明方案中所述触摸板和所述显示屏的分辨率相同，例如显示屏分辨率为300×200，触摸板的分辨率也为300×200。
具体的，上述触控区域可以是规则形状的区域，还可以是不规则形状的区域。在上述触控区域为不规则形状的区域的情况下，可以以构成该区域的各个像素点的像素点坐标表示；在上述触控区域为规则形状的区域的情况下，可以以该规则形状的区域对应的特征点的坐标表示，例如，上述触控区域为矩形时，上述特征点可以是矩形的左上角顶点和右下角顶点等等。
由于触摸板的分辨率与显示屏的分辨率相同，所以可以直接根据该分辨率之间的关系，针对显示屏所显示图像获得第一触控区域对应的第二触控区域。
具体的，上述第一触控区域在触摸板上对应的区域以及区域内各个像素点的坐标，通常与上述第二触控区域在显示屏所显示图像上的对应区域以及区域内各个像素点的坐标相同。
例如：用户在触摸板上进行点击操作，触摸板接收到触控指令，上述第一触控区域为矩形区域，处理器获得该触控指令对应的第一触控区域的左上角顶点坐标为120×100、右下角顶点坐标为140×120，因为触摸板的分辨率和显示屏的分辨率相等，所以可以获得显示图像中的第二触控区域也为矩形区域，且第二触控区域的左上角顶点坐标也为120×100、右下角顶点坐标也为140×120。
步骤S102：获得所述显示屏所显示图像与当前投影图像之间的横向显示比例m和纵向显示比例n。
其中，所述横向显示比例m：由所述显示屏分辨率的横向分量和当前投影图像分辨率的横向分量确定，所述纵向显示比例n：由所述显示屏分辨率的纵向分量和当前投影图像分辨率的纵向分量确定。
在本申请的一种具体实现方式中，显示屏所显示图像的具体内容可以与当前投影图像的具体内容完全相同，这种情况下，
所述横向显示比例m可以等于当前投影图像分辨率的横向分量与所述显示屏分辨率的横向分量之间的比值；
所述纵向显示比例n可以等于当前投影图像分辨率的纵向分量与所述显示屏分辨率的纵向分量之间的比值。
例如：当前投影图像分辨率为1500×900，显示屏分辨率为300×200，则显示屏所显示图像与当前投影图像之间的横向显示比例m＝1500/300＝5，显示屏所显示图像与当前投影图像之间的纵向显示比例n＝900/200＝4.5。
需要说明的是，本申请中所提及的投影图像的分辨率可以理解为投影设备的分辨率。
另外，本申请实施例所提供的方案适用于分辨率可调的投影设备，也适用于分辨率不可调的投影设备，本申请并不对此进行限定。
进一步的，上述横向显示比例m可以与上述纵向显示比例n相等，也可以不相等。
较佳的，在上述横向显示比例m和上述纵向显示比例n相等的情况下，投影图像的宽度和高度与显示屏所显示图像的宽度和高度成等比例，这样用户在投影背景上看到的图像与在显示屏上看到的图像是一致的、无畸变的。
本领域内的技术人员可以理解的，上述横向显示比例m和纵向显示比例n的取值可以为整数，也可以为非整数。
在本申请的一种较佳实现方式中，上述横向显示比例m和上述纵向显示比例n均为正整数，这样显示屏所显示图像中的一个像素点可以正好对应于投影图像中正整数个像素点，这样在确定像素点之间的对应关系时不会出现像素点之间的偏差。
步骤S103：根据所述横向显示比例m和所述纵向显示比例n，确定所述第二触控区域在当前投影图像上对应的第三触控区域。
由前述描述得知，显示屏所显示图像的具体内容可以与当前投影图像的具体内容完全相同，横向显示比例m可以等于当前投影图像分辨率的横向分量与显示屏分辨率的横向分量之间的比值，纵向显示比例n可以等于当前投影图像分辨率的纵向分量与显示屏分辨率的纵向分量之间的比值。所以，这种情况下，所述第三触控区域内各个像素点的坐标的横向分量可以通过第二触控区域内相应像素点的坐标的横向分量乘以所述横向显示比例m来获得；所述第三触控区域内各个像素点的坐标的纵向分量可以通过第二触控区域内相应像素点的坐标的纵向分量乘以所述纵向显示比例n来获得。
假设，第二触控区域内一像素点P的坐标为120×100，横向显示比例m＝5、纵向显示比例n＝4.5，那么像素点P在第三触控区域内对应的像素点的坐标的横向分量为120×5＝600、纵向分量为100×4.5＝450，也就是像素点P在第三触控区域内对应的像素点的坐标为600×450。
实际应用中，在所述横向显示比例m和/或所述纵向显示比例n为非整数的情况下，确定所述第二触控区域在当前投影图像上对应的第三触控区域时，由于可能会存在像素偏差，从而导致第三触控区域相对于第二触控区域存在细微偏差。但是，可以理解的是，本领域内的技术人员可以通过设置适当的当前投影图像分辨率，使得所述横向显示比例m和所述纵向显示比例n均为整数，这样可以避免确定第三触控区域时的细微偏差。
步骤S104：根据所述第三触控区域和当前投影图像，解析所述触控指令。
具体的，根据当前投影图像上的第三触控区域的图像内容以及触控指令，进行解析，得到解析结果。
例如：从步骤S103获得第三触控区域为一矩形区域，当前投影图像中该矩形区域对应的图像内容为某视频应用图标，所述触控指令为由点击操作生成的，因此可以得到解析结果为打开该视频应用。
步骤S105：根据解析结果，针对当前投影图像响应所述触控指令。
例如：从步骤S104获得触控指令的解析结果为打开某视频应用，本步骤中响应上述触控指令，可以理解为打开该视频应用，并且进一步的投影图像中可以显示该视频应用打开后的界面。
由以上可见，本发明实施例中，根据所述显示屏所显示图像与当前投影图像之间的横向显示比例m和纵向显示比例n，可以将触摸板和当前投影图像进行精确对应，从而实现对当前投影图像的精确控制。
具体的，前述显示屏所显示图像可以由第一预设数量个显示子界面叠加而成，并且每个显示子界面可以通过独立的开关进行单独的显示控制。
例如：上述显示图像由三个显示子界面叠加而成，每个显示子界面通过独立的开关进行单独的显示控制。如果关断其中一个显示子界面，那么显示图像就发生了变化，变成由两个显示子界面叠加而成。
上述当前投影图像可以由第二预设数量个投影子界面叠加而成，每个投影子界面可以通过独立的开关进行单独的投影控制。
和上述显示图像相似，每个投影子界面通过独立的开关进行单独的投影控制。例如：当前投影图像由三个投影子界面叠加而成，如果关断其中一个投影子界面，那么当前投影图像就发生了变化，变成由两个投影子界面叠加而成。
本发明方案中，上述第一预设数量和上述第二预设数量可以相等，例如：显示图像由三个显示子界面叠加而成，当前投影图像也由三个投影子界面叠加而成，此时，所述显示图像和当前投影图像显示的内容相同。
所述第一预设数量和所述第二预设数量也可以不相等，此时，所述显示图像和当前投影图像显示的内容不相同。例如：显示图像由三个显示子界面叠加而成，三个显示子界面分别对应显示的是视频内容、视频控制按钮、***时间，而当前投影图像由两个投影子界面叠加而成，两个投影子界面分别对应显示的是视频内容、***时间，还有一个视频控制按钮显示子界面对应的投影子界面未投影显示出来。
基于上述描述，在本申请的一种具体实现方式中，参见图2，提供了另一种针对投影图像的触控方法的流程示意图，应用于包括触摸板和显示屏的投影设备，其中，所述触摸板和所述显示屏的分辨率相同，与前述实施例相比，本实施例中，步骤S103包括：
步骤S103A：获得所述第二触控区域对应的第一显示子界面。
本领域内的技术人员可以理解的是，构成上述显示图像的显示子界面的大小可以相等，也可以不相等，本申请并不对此进行限定。
在各个显示子界面的大小相等的情况下，为了保证用户能够清晰的看到各个子界面中的内容，通常情况下，各个子界面中包含内容画面的部分是不重合的，所以，获得第二触控区域对应的第一显示子界面时，可以通过查看各个子界面中第二触控区域对应的位置是否包含内容画面的方式获得上述第一显示子界面，具体的，可以确定第二触控区域对应的位置包含内容画面的子界面为上述第一显示子界面。
在各个显示子界面的大小不相等的情况下，获得第二触控区域对应的第一显示子界面时，可以直接根据第二触控区域的位置对应的子界面为上述第一显示子界面。
步骤S103B：获得所述第一显示子界面对应的第一投影子界面。
具体的，可以根据上述第一显示子界面的标识、显示子界面与投影子界面之间的对应关系等等获得第一显示子界面对应的第一投影子界面。
例如：通过步骤S103A获得第一显示子界面为视频控制按钮显示子界面，从而获得视频控制按钮显示子界面对应的第一投影子界面为视频控制按钮投影子界面。
步骤S103C：根据所述横向显示比例m和所述纵向显示比例n，确定所述第二触控区域在所述第一投影子界面上对应的第三触控区域。
在实际应用中，和前述实施例中S103中所描述的方法相类似，在显示屏显示的图像与投影图像完全相同的情况下，所述第三触控区域中任一像素点P的坐标的横向分量，可以通过像素点P在第二触控区域中对应像素点的坐标的横向分量乘以所述横向显示比例m来获得；所述第三触控区域中任一像素点P的坐标的纵向分量，可以通过像素点P在第二触控区域中对应像素点的坐标的纵向分量乘以所述纵向显示比例n来获得。所不同的是，前述实施例中，确定的第三触控区域在当前投影图像上，而本实施例中，确定的第三触控区域在所述的第一投影子界面上。
以确定第二触控区域中任一像素点在第三触控区域中的对应像素点为例，简述确定第二触控区域在第一投影子界面上对应的第三触控区域的方法如下：
假设，第二触控区域中一像素点P的坐标为150×100，上述横向显示比例m＝4、上述纵向显示比例n＝4，那么可以确定像素点P在第三触控区域中对应的像素点的坐标的横向分量为150×4＝600、纵向分量为100×4＝400，也就是像素点P在第三触控区域中对应的像素点的坐标为600×400。
步骤S104具体为
步骤S104A：根据所述第三触控区域和所述第一投影子界面，解析所述触控指令。
具体的，根据第一投影子界面上的第三触控区域的图像内容以及触控指令，进行解析， 得到解析结果。
例如：第一投影子界面中第三触控区域对应的内容为视频暂停按钮，所述触控指令为由点击操作生成的，因此可以得到解析结果为暂停播放当前视频。
在本发明的一种可选实现方式中，上述针对投影图像的触控方法还可以包括：
接收针对所述投影设备的操作指令，根据所述操作指令以及所述投影设备的当前模式，确定所述显示屏待显示图像包括的显示子界面以及待投影图像包括的投影子界面，根据所确定的显示子界面在所述显示屏上显示所述待显示图像，并根据所确定的投影子界面显示所述待投影图像。
具体的，上述操作指令可以是通过点击操作唤醒处于休眠状态的投影设备的操作指令，也可以是通过在处于待机状态的投影设备上滑动启动该投影设备的操作指令等等，本申请对此不作限定。
所述投影设备的当前模式可以是休眠模式、待机模式等等，本申请对此不作限定。
例如：所述投影设备当前处于休眠模式，所述操作指令为通过点击该投影设备唤醒该投影设备的指令，由此可以确定显示屏待显示图像的显示子界面包括：主图像显示子界面、时间显示子界面，待投影图像无投影子界面。当所述投影设备处于待机模式时，所述操作指令为通过在该投影设备上滑动以启动该投影设备的指令，由此可以确定显示屏待显示图像的显示子界面包括：主图像显示子界面、时间显示子界面，待投影图像的投影子界面包括：主图像显示子界面、时间显示子界面。
当确定的显示子界面包括：主图像显示子界面、时间显示子界面，投影无子界面时，显示屏上显示主图像和时间，投影屏幕上无投影图像。当确定的显示子界面包括：主图像显示子界面、时间显示子界面，确定的投影子界面包括：主图像显示子界面、时间显示子界面时，显示屏上显示主图像和时间，且投影屏幕上也投影显示主图像和时间。
由以上可见，本发明实施例中，显示图像可以和当前投影图像不相同，用户可以根据需要分别进行显示和投影，通过所述横向显示比例m和纵向显示比例n，可以将触摸板和当前投影图像进行精确对应，从而实现对当前投影图像的精确控制，更加贴合用户的需求。
图3为本发明实施例提供的另一种针对投影图像的触控方法的流程示意图，应用于包括触摸板和显示屏的投影设备，其中，所述触摸板和所述显示屏的分辨率相同，与图1所示实施例相比，本实施例中，所述显示图像对应于当前投影图像中的预设局部图像。
局部图像的具***置可以根据当前投影图像来预先设定。例如：当前投影图像为视频时，上述局部图像可以为当前视频图像中的视频按钮区域，该视频按钮区域在不同的视频图像中 处于固定的位置。
步骤S103包括步骤S103D、步骤S103E，其中，
步骤S103D：根据所述横向显示比例m和所述纵向显示比例n，确定所述第二触控区域在所述预设局部图像上对应的第四触控区域。
在本实施例中，所述横向显示比例m：由所述显示屏分辨率的横向分量、当前投影图像分辨率的横向分量以及预设局部图像分辨率的横向分量确定；所述纵向显示比例n：由所述显示屏分辨率的纵向分量、当前投影图像分辨率的纵向分量，以及预设局部图像分辨率的纵向分量确定。
例如：显示屏分辨率为300×200，当前投影图像分辨率为1200×800，预设局部图像的分辨率为600×200。所以可以得到，横向显示比例m＝600/300＝2，纵向显示比例n＝200/200＝1。
具体的，所述第四触控区域内每一像素点的坐标的横向分量可以通过第二触控区域内对应像素点的坐标的横向分量乘以所述横向显示比例m来获得；所述第三触控区域内每一像素点的坐标的纵向分量可以通过第二触控区域内对应像素点的坐标的纵向分量乘以所述纵向显示比例n来获得。
步骤S103E：根据所述预设局部图像在当前投影图像中的位置以及所述第四触控区域，获得所述第二触控区域在当前投影图像上对应的第三触控区域。
具体的，根据所述预设局部图像在当前投影图像中的位置可以得到所述预设局部图像的位移量，包括横向位移量和纵向位移量；所述第三触控区域的坐标的横向分量可以通过第四触控区域的坐标的横向分量加上所述预设局部图像的横向位移量来获得；所述第三触控区域的坐标的纵向分量可以通过第四触控区域的坐标的纵向分量加上所述预设局部图像的纵向位移量来获得。
例如：根据预设局部图像在当前投影图像中的位置，得到预设局部图像的横向位移量为200，纵向位移量为500。从步骤S103D获得第四触控区域中一个像素点P的坐标为300×100，可以得到像素点P在第三触控区域中对应像素点的坐标为500×600。
