附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对本公开实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本公开的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

图4是本公开另一实施例提供的移动终端的结构图。
具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行 清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，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，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的检测方法的流程图，如图1所示，本实施例提供一种检测方法，应用于移动终端，所述移动终端包括驱动组件和摄像头，所述驱动组件用于驱动所述摄像头伸出所述移动终端或者缩回所述移动终端，所述方法包括以下步骤：
步骤101、在检测到所述驱动组件开始驱动所述摄像头移动的情况下，获取输入到所述驱动组件中的电流值。
驱动组件与电源连接，驱动组件工作时，电源为驱动组件提供电源信号。电源信号包括电压和电流。驱动组件开始驱动摄像头伸出或者缩回时，移动终端获取输入到驱动组件中的电流值。驱动组件可为电机。
获取电流值时，可每隔预设时间间隔获取一次，在此不做限定。
步骤102、根据预设时间内所述电流值的变化量，判断所述摄像头是否移动到预设位置。
驱动组件驱动摄像头伸出的过程中，若摄像头被卡住，输入驱动组件中的电流值会突变，电流值突变可理解为，在预设时间内所述电流值的变化量大于第一预设阈值。移动终端根据电流值是否突变，并根据电流值发生突变的时间，判断摄像头是否移动到预设位置。
进一步的，所述根据预设时间内所述电流值的变化量，判断所述摄像头是否移动到预设位置，包括：
若在所述预设时间内所述电流值的变化量大于第一预设阈值，则确定所述驱动组件开始驱动所述摄像头移动的起始时刻与所述预设时间内所述电流值最大的时刻之间的时长；
根据所述时长，判断所述摄像头是否移动到预设位置。
具体的，预设时间可根据实际情况进行设置，在此不做限定。移动终端检测到在预设时间内所述电流值的变化量大于第一预设阈值时，确定所述驱动组件开始驱动所述摄像头移动的起始时刻与所述预设时间内所述电流值最大的时刻之间的时长。
在驱动组件驱动所述摄像头伸长的情况下，预设位置为摄像头在正常工作(即摄像头在伸出或缩回的过程中，除驱动组件外，无其他影响摄像头移动的遮挡物)的情况下伸出的终点位置；在驱动组件驱动所述摄像头缩回的情况下，预设位置为摄像头在正常工作的情况下缩回的终点位置。摄像头在正常工作时，摄像头从开始伸出至预设位置的时间为预设时长，或者摄像头从开始缩回至预设位置的时间为预设时长，将该预设时长作为第二预设阈值，通过比较时长和第二预设阈值，可判断摄像头是否伸出到预设位置，或者缩回到预设位置。
本公开实施例中，上述移动终端可以为任何包括伸缩摄像头的移动终端，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等。
本公开实施例的检测方法，在检测到所述驱动组件开始驱动所述摄像头移动的情况下，获取输入到所述驱动组件中的电流值；根据预设时间内所述电流值的变化量，判断所述摄像头是否移动到预设位置，这样，通过对输入到驱动组件中的电流值进行判断，便可判断摄像头是否移动到预设位置，可降低移动终端的制造成本。
进一步的，所述根据所述时长，判断所述摄像头是否移动到预设位置，包括：
若所述时长大于第二预设阈值，则判定摄像头移动到预设位置；
若所述时长不大于第二预设阈值，则判定摄像头未移动到预设位置。
例如，摄像头从开始伸出至预设位置需要1秒时间(1秒即为第二预设阈值)，若时长属于0秒到0.95秒区间，说明电流值发生突变在0秒到0.95秒区间，判定摄像头在伸缩过程中被挡住，摄像头未伸出到预设位置；若时长属于0.95秒到1秒区间，说明电流值发生突变在0.95秒到1秒区间，判定摄像头已经伸缩到位，即摄像头伸出到预设位置。
同样的，若摄像头从开始缩回至预设位置需要1秒时间(1秒即为第二预设阈值)，若时长属于0秒到0.95秒区间，说明电流值发生突变在0秒到0.95秒区间，判定摄像头在缩回过程中被挡住，摄像头未缩回到预设位置； 若时长属于0.95秒到1秒区间，说明电流值发生突变在0.95秒到1秒区间，判定摄像头已经缩回到位，即摄像头缩回到预设位置。
本公开实施例的检测方法，通过驱动组件驱动所述摄像头移动的起始时刻和电流值发生突变的时间确定时长，然后根据时长和第二预设阈值，判断摄像头是否移动到预设位置，可降低移动终端的制造成本。
进一步的，若判定摄像头在伸出过程中被挡住，则移动终端控制驱动组件驱动摄像头缩回，以防止摄像头损坏，有效保护摄像头；若判定摄像头已移动到预设位置，则移动终端控制驱动组件停止驱动摄像头。
若判定摄像头在缩回过程中被挡住，则移动终端控制驱动组件驱动摄像头停止移动，以防止摄像头损坏，有效保护摄像头。
进一步的，在检测到所述驱动组件开始驱动所述摄像头移动的情况下，获取输入到所述驱动组件中的电流值，包括：
在检测到所述驱动组件开始驱动所述摄像头移动的情况下，获取起始时刻输入到所述驱动组件中的第一电流值；
若在预设时间内所述电流值的变化量大于第一预设阈值，则确定所述驱动组件开始驱动所述摄像头移动的起始时刻与所述预设时间内所述电流值最大的时刻之间的时长，包括：
获取目标时刻输入到所述驱动组件中的第二电流值；
若所述第一电流值与所述第二电流值的差值大于第一预设阈值，则确定所述起始时刻与所述目标时刻之间的时长。
具体的，在检测到驱动组件驱动摄像头移动的情况下，获取摄像头开始移动的起始时刻，并获取起始时刻输入到所述驱动组件中的第一电流值。
获取电流值时，可每隔预设时间间隔获取一次。例如，若起始时刻为0秒，那么可每隔0.2秒获取驱动组件的电流值，例如在0.2秒、0.4秒和0.6秒时获取驱动组件的电流值。目标时刻即为获取第二电流值的时刻。当第一电流值与第二电流值的差值大于第一预设阈值时，确定所述起始时刻与所述目标时刻之间的时长。若所述时长大于第二预设阈值，则判定摄像头移动到预设位置；若所述时长不大于第二预设阈值，则判定摄像头未移动到预设位置。
本公开实施例的检测方法，通过驱动组件驱动所述摄像头移动的起始时刻和目标时刻确定时长，以便根据时长和第二预设阈值，判断摄像头是否移动到预设位置，可降低移动终端的制造成本。

根据所述时长，判断所述摄像头是否移动到预设位置。
具体的，驱动组件2驱动摄像头1移动的过程中，若摄像头1被卡住，输入驱动组件2中的电流值会发生突变，即电流值的变化量大于第一预设阈值。移动终端可根据电流值发生突变的时间，判断摄像头1是否移动到预设位置。例如，驱动组件2驱动摄像头1伸出的过程中，若摄像头1被卡住，输入驱动组件2中的电流值会突变。移动终端根据电流值突变的时间，判断摄像头1是否伸出到预设位置。或者，驱动组件2驱动摄像头1缩回的过程中，若摄像头1被卡住，输入驱动组件2中的电流值会突变。移动终端根据电流值突变的时间，判断摄像头1是否缩回到预设位置。
移动终端在检测到电流值发生突变，根据驱动组件2驱动摄像头1伸出 的起始时刻与预设时间内所述电流值最大的时刻获得时长，该时长为电流值发生突变时驱动组件2驱动摄像头1伸出过程中所使用的时长。
预设位置为摄像头1在正常工作的情况下伸出的终点位置，或者摄像头1在正常工作的情况下缩回的终点位置。摄像头1在正常工作时，摄像头1从开始伸出至预设位置的时间为预设时长，或者摄像头1从开始缩回至预设位置的时间为预设时长，将该预设时长作为第二预设阈值，通过比较时长和第二预设阈值，可判断摄像头1是否移动到预设位置。
进一步的，所述控制模块5还用于：
若所述时长大于第二预设阈值，判定摄像头移动到预设位置；
若所述时长不大于第二预设阈值，判定摄像头未移动到预设位置。
例如，摄像头1从开始伸出至预设位置需要1秒时间(1秒即为第二预设阈值)，若时长属于0秒到0.95秒区间，说明电流值发生突变在0秒到0.95秒区间，判定摄像头1在伸缩过程中被挡住，摄像头1未伸出到预设位置；若时长属于0.95秒到1秒区间，说明电流值发生突变在0.95秒到1秒区间，判定摄像头1已经伸缩到位，即摄像头1伸出到预设位置。
同样的，若摄像头从开始缩回至预设位置需要1秒时间(1秒即为第二预设阈值)，若时长属于0秒到0.95秒区间，说明电流值发生突变在0秒到0.95秒区间，判定摄像头在缩回过程中被挡住，摄像头未缩回到预设位置；若时长属于0.95秒到1秒区间，说明电流值发生突变在0.95秒到1秒区间，判定摄像头已经缩回到位，即摄像头缩回到预设位置。
本公开实施例中，通过驱动组件2驱动所述摄像头1移动的起始时刻和电流值发生突变的时间确定时长，然后根据时长和第二预设阈值，判断摄像头1是否移动到预设位置，可降低移动终端的制造成本。

用户输入单元507可用于接收输入的数字或字符信息，以及产生与移动终端的用户设置以及功能控制有关的键信号输入。具体地，用户输入单元507包括触控面板5071以及其他输入设备5072。触控面板5071，也称为触摸屏，可收集用户在其上或附近的触摸操作(比如用户使用手指、触笔等任何适合的物体或附件在触控面板5071上或在触控面板5071附近的操作)。触控面板5071可包括触摸检测装置和触摸控制器两个部分。其中，触摸检测装置检测用户的触摸方位，并检测触摸操作带来的信号，将信号传送给触摸控制器；触摸控制器从触摸检测装置上接收触摸信息，并将它转换成触点坐标，再送给处理器510，接收处理器510发来的命令并加以执行。此外，可以采用电阻式、电容式、红外线以及表面声波等多种类型实现触控面板5071。除了触控面板5071，用户输入单元507还可以包括其他输入设备5072。具体地，其他输入设备5072可以包括但不限于物理键盘、功能键(比如音量控制按键、开关按键等)、轨迹球、鼠标、操作杆，在此不再赘述。
进一步的，触控面板5071可覆盖在显示面板5061上，当触控面板5071检测到在其上或附近的触摸操作后，传送给处理器510以确定触摸事件的类型，随后处理器510根据触摸事件的类型在显示面板5061上提供相应的视觉输出。虽然在图4中，触控面板5071与显示面板5061是作为两个独立的部件来实现移动终端的输入和输出功能，但是在某些实施例中，可以将触控面 板5071与显示面板5061集成而实现移动终端的输入和输出功能，具体此处不做限定。
接口单元508为外部装置与移动终端500连接的接口。例如，外部装置可以包括有线或无线头戴式耳机端口、外部电源(或电池充电器)端口、有线或无线数据端口、存储卡端口、用于连接具有识别模块的装置的端口、音频输入/输出(input/output，I/O)端口、视频I/O端口、耳机端口等等。接口单元508可以用于接收来自外部装置的输入(例如，数据信息、电力等等)并且将接收到的输入传输到移动终端500内的一个或多个元件或者可以用于在移动终端500和外部装置之间传输数据。
存储器509可用于存储软件程序以及各种数据。存储器509可主要包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等；存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外，存储器509可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器510是移动终端的控制中心，利用各种接口和线路连接整个移动终端的各个部分，通过运行或执行存储在存储器509内的软件程序和/或模块，以及调用存储在存储器509内的数据，执行移动终端的各种功能和处理数据，从而对移动终端进行整体监控。处理器510可包括一个或多个处理单元；可选的，处理器510可集成应用处理器和调制解调处理器，其中，应用处理器主要处理操作系统、用户界面和应用程序等，调制解调处理器主要处理无线通信。可以理解的是，上述调制解调处理器也可以不集成到处理器510中。
移动终端500还可以包括给各个部件供电的电源511(比如电池)，可选的，电源511可以通过电源管理系统与处理器510逻辑相连，从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外，移动终端500包括一些未示出的功能模块，在此不再赘述。
可选的，本公开实施例还提供一种移动终端，包括处理器510，存储器509，存储在存储器509上并可在所述处理器510上运行的计算机程序，该计算机程序被处理器510执行时实现上述检测方法实施例的各个过程，且能达 到相同的技术效果，为避免重复，这里不再赘述。
本公开实施例还提供一种计算机可读存储介质，计算机可读存储介质上存储有计算机程序，该计算机程序被处理器执行时实现上述检测方法实施例的各个过程，且能达到相同的技术效果，为避免重复，这里不再赘述。其中，所述的计算机可读存储介质，如只读存储器(Read-Only Memory，ROM)、随机存取存储器(Random Access Memory，RAM)、磁碟或者光盘等。
需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端(可以是手机，计算机，服务器，空调器，或者网络设备等)执行本公开各个实施例所述的方法。上面结合附图对本公开的实施例进行了描述，但是本公开并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
