步骤S101，移动终端拍摄图像；
在本实施例中，移动终端可以是手机或者平板电脑等。可以为移动终端增加了一种夜拍拍摄模式，用户可以选择该拍摄模式或普通拍摄模式进行拍摄图像，其中，夜拍拍摄模式结合夜间拍摄场景的要求，预先设定了曝光时间、ISO(感光元件的感光速度)、分辨率、曝光补偿、降噪等参数，还可以根据不同地区不同的星空场景预设不同的参数，供用户拍摄时进行选择。
当用户选择了夜拍拍摄模式，按下拍摄按键或触发虚拟拍摄按键后，移动终端的摄像头进行拍摄，并按照预设的次数进行曝光，如曝光5～10秒。
本实施例中，移动终端也可以显示不同的星座模板，以供用户进行参考，然后再进行拍摄。
本实施例在天气较晴朗的夜间进行拍摄，在大雾天或者环境污染较严重时，不适合拍摄。
本实施例中，移动终端也可以拍摄星轨视频，将所拍摄的图像进行合成处理可以得到星轨视频，例如，将拍摄的第一张图像与第二张图像进行亮度合成处理，得到第一合成图像，将第三张图像与第一合成图像进行亮度合成处理，得到第二合成图像，依次类推，直至全部合成，将第一张图像与所有的合成图像进行编码处理，最终生成星轨视频。星轨视频中星星为运动状态，可以取每个运动的端点作为星星当前的位置，然后可以在星轨视频中进行星座的匹配。
步骤S102，将所述图像与所述移动终端中预存的星座模板进行匹配；
本实施例中，在移动终端中预存星座模板，该星座模板包括星座所包括的所有星星，每个星星的相对位置等。有些星座在不同的时间其方位或朝向会发生改变，如北斗星，因此，相对位置包括多种。在其他实施例中，也可以以星星的亮度作为一个附加的匹配，但考虑天气及环境污染等条件，星星的亮度仅作次要的匹配。
本实施例中，可以为不同的地理位置、不同的时间设置星座模板。地理位置可以是基于一经度及纬度范围内的一个区域，而一个月中或者一年中不同的时间，星座的方位或朝向可能发生改变，此时设置该星座的多个星座模板。
本实施例中，可以预定一星星作为参考，然后取得该星座的其他星星的与该星星的相对位置信息，再与星座模板进行匹配。
本实施例中，可以由用户进行手动匹配，如在移动终端上输入星座的名称或者位置信息进行搜索，得到星座模板，然后进行逐个匹配；或者由移动终端自动进行匹配。
本实施例中，如果拍摄的是星轨视频，可以将星轨视频与星座模板进行匹配，然后在星轨视频中识别出不同的星座。
步骤S103，当匹配成功时，在所述图像中标识出对应的星座。
本实施例中，在用户所拍摄的图像与星座模板匹配成功时，图像上标识
出对应的星座，并可以标识出相应的星座名称。
本实施例中，可以将星座的每个星星以连线的方式标识，或者以闪烁的方式进行标识，或者以其他能够醒目的方式进行标识，等等，以提醒用户。
本实施例中，如果拍摄的是星轨视频，可以在星轨视频中标识出星座，如以连线的方式或者闪烁的方式，其中，连线及闪烁与运动轨迹的颜色要不同，以起到标识作用。由于星轨视频为动态，因此，星座也跟随运动。
与相关技术相比，本实施例通过在移动终端中预置星座模板，在用户拍摄星空照片后，可以将所拍摄的照片与星座模板进行匹配，如能够匹配成功，则能识别出对应的星座，在照片上标识出该星座，本实施例在用户拍摄星空照片后，不需要用户进行仔细辨认即能够找到星座，方便快捷，并可提高用户体验。
在一实施例中，在上述图1的实施例的基础上，本实施例在将图像与所述移动终端中预存的星座模板进行匹配的步骤之前包括以下步骤：获取用户当前的位置信息；向用户推送与所述位置信息对应的星座模板，以将所述图像与所推送的星座模板进行匹配。
本实施例中，可以在移动终端中内置定位装置，如GPS等，或者通过移动运营网的基站的定位，得到移动终端的位置信息。位置信息是基于一经度及纬度范围内的一个区域。
在获取移动终端的位置信息后，可以预测该位置出现的星座，移动终端获取该位置出现的星座的星座模板，然后向用户推送，显示在移动终端的屏幕上，用户可以参考显示的星座模板进行拍摄，或者由移动终端直接将所拍摄的图像与所推送的星座模板进行匹配，以提高匹配的速度。
在一实施例中，如图2所示，在上述图1的实施例的基础上，上述步骤S102包括：
步骤S1021，判断所述图像中的像素的亮度是否大于预设值；
步骤S1022，若是，选出所述像素，将所选出的像素的相对位置与所述
星座模板中的像素的相对位置对应进行匹配。
本实施例中，在用户所拍摄的图像中，移动终端判断图像中的像素的亮度是否大于预设值，如果大于，则认为该像素为星星，若图像中的像素的亮度不大于预设值时，舍弃该像素，从而对亮度较低的像素进行了一定程度的过滤，避免了环境光的累计效果对图像造成影响。
本实施例选出像素，即选出图像中所有的星星，将其与星座模板中的像素进行相对位置的匹配。
在一实施例中，如图3所示，在上述图1的实施例的基础上，本实施例在上述步骤S101之前还包括：
步骤S100，获取星座信息，基于所述星座信息生成星座模板，将所述星座模板存储于星座数据库中。
本实施例中，星座信息包括星座名称、星星数量及每个星星的相对位置等，另外还可以包括每个星星的亮度等。本实施例中，移动终端包括所有星座的星座模板。
本实施例中，基于星座信息生成星座模板，将星座模板存储在星座数据库中，以备做星座匹配之用。

匹配模块102，设置为：将所述图像与所述移动终端中预存的星座模板进行匹配；
本实施例中，在移动终端中预存星座模板，该星座模板包括星座所包括的所有星星，每个星星的相对位置等。有些星座在不同的时间其方位或朝向会发生改变，如北斗星，因此，相对位置包括多种。在其他实施例中，也可以以星星的亮度作为一个附加的匹配，但考虑天气及环境污染等条件，星星的亮度仅作次要的匹配。
本实施例中，可以为不同的地理位置、不同的时间设置星座模板。地理位置可以是基于一经度及纬度范围内的一个区域，而一个月中或者一年中不同的时间，星座的方位或朝向可能发生改变，此时设置该星座的多个星座模板。
本实施例中，可以预定一星星作为参考，然后取得该星座的其他星星的与该星星的相对位置信息，再与星座模板进行匹配。
本实施例中，可以由用户进行手动匹配，如在移动终端上输入星座的名称或者位置信息进行搜索，得到星座模板，然后进行逐个匹配；或者由移动终端自动进行匹配。
本实施例中，如果拍摄的是星轨视频，可以将星轨视频与星座模板进行
匹配，然后在星轨视频中识别出不同的星座。
标识模块103，设置为：当匹配成功时，在所述图像中标识出对应的星座。
本实施例中，在用户所拍摄的图像与星座模板匹配成功时，图像上标识出对应的星座，并可以标识出相应的星座名称。
本实施例中，可以将星座的每个星星以连线的方式标识，或者以闪烁的方式进行标识，或者以其他能够醒目的方式进行标识，等等，以提醒用户。
本实施例中，如果拍摄的是星轨视频，可以在星轨视频中标识出星座，如以连线的方式或者闪烁的方式，其中，连线及闪烁与运动轨迹的颜色要不同，以起到标识作用。由于星轨视频为动态，因此，星座也跟随运动。
与相关技术相比，本实施例通过在移动终端中预置星座模板，在用户拍摄星空照片后，可以将所拍摄的照片与星座模板进行匹配，如能够匹配成功，则能识别出对应的星座，在照片上标识出该星座，本实施例在用户拍摄星空照片后，不需要用户进行仔细辨认即能够找到星座，方便快捷，并可提高用户体验。
在一实施例中，在上述图4的实施例的基础上，移动终端还包括：获取模块，设置为：获取用户当前的位置信息；推送模块，设置为：向用户推送与所述位置信息对应的星座模板，以将所述图像与所推送的星座模板进行匹配。
本实施例中，可以在移动终端中内置定位装置，如GPS等，或者通过移动运营网的基站的定位，得到移动终端的位置信息。位置信息是基于一经度及纬度范围内的一个区域。
在获取移动终端的位置信息后，可以预测该位置出现的星座，移动终端获取该位置出现的星座的星座模板，然后向用户推送，显示在移动终端的屏幕上，用户可以参考显示的星座模板进行拍摄，或者由移动终端直接将所拍摄的图像与所推送的星座模板进行匹配，以提高匹配的速度。
在一实施例中，如图5所示，在上述图4的实施例的基础上，所述匹配模块102包括：
判断单元1021，设置为：判断所述图像中的像素的亮度是否大于预设值；
匹配单元1022，设置为：若所述图像中的像素的亮度大于预设值，选出所述像素，将所选出的像素的相对位置与所述星座模板中的像素的相对位置对应进行匹配。
本实施例中，在用户所拍摄的图像中，移动终端判断图像中的像素的亮度是否大于预设值，如果大于，则认为该像素为星星，若图像中的像素的亮度不大于预设值时，舍弃该像素，从而对亮度较低的像素进行了一定程度的过滤，避免了环境光的累计效果对图像造成影响。
本实施例选出像素，即选出图像中所有的星星，将其与星座模板中的像素进行相对位置的匹配。
在一实施例中，如图6所示，在上述图4的实施例的基础上，所述移动终端还包括：
生成模块100，设置为：获取星座信息，基于所述星座信息生成星座模板，将所述星座模板存储于星座数据库中。
本实施例中，星座信息包括星座名称、星星数量及每个星星的相对位置等，另外还可以包括每个星星的亮度等。本实施例中，移动终端包括所有星座的星座模板。
本实施例中，基于星座信息生成星座模板，将星座模板存储在星座数据库中，以备做星座匹配之用。
本领域普通技术人员可以理解上述实施例的全部或部分步骤可以使用计算机程序流程来实现，所述计算机程序可以存储于一计算机可读存储介质中，所述计算机程序在相应的硬件平台上(如系统、设备、装置、器件等)执行，在执行时，包括方法实施例的步骤之一或其组合。
可选地，上述实施例的全部或部分步骤也可以使用集成电路来实现，这些步骤可以被分别制作成一个个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。
上述实施例中的装置/功能模块/功能单元可以采用通用的计算装置来实现，它们可以集中在单个的计算装置上，也可以分布在多个计算装置所组成的网络上。
上述实施例中的装置/功能模块/功能单元以软件功能模块的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。上述提到的计算机可读取存储介质可以是只读存储器，磁盘或光盘等。
本发明实施例通过在移动终端中预置星座模板，在用户拍摄星空照片后，可以将所拍摄的照片与星座模板进行匹配，如能够匹配成功，则能识别出对应的星座，在照片上标识出该星座。本发明实施例在用户拍摄星空照片后，不需要用户进行仔细辨认即能够找到星座，方便快捷，并可提高用户体验。
