Description

投影处理方法及装置 技术领域
本申请涉及但不限于通信领域，具体而言，涉及一种投影处理方法及装置。
背景技术
智能微型投影机(以下简称微投)以其携带方便、功能强大等优点，普及率日益提高，微投被广泛用于家庭娱乐、商家广告投影、商务会议投影等场景。当前对微投的操作，或直接接触微投屏幕进行触摸操作，或通过激光笔和遥控器来对微投进行操作。
直接接触微投屏幕进行触摸操作时，微投通常放在一个固定的地方，人与微投会有一定的距离，触摸操作并不方便，而且直接触控微投触控屏幕，还可能会引起手指触控碰及微投造成画面抖动。

本发明的实施方式
下文中将参考附图并结合实施例来详细说明本发明实施例。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在本实施例中提供了一种投影处理方法，图1是根据本发明实施例的投影处理方法的流程图一，如图1所示，该流程包括如下步骤：
步骤S102，检测到对终端进行操作的第一操作信号；
步骤S104，根据检测到的第一操作信号，向支持与终端通信的投影器发送对应的第一投影处理指令，其中，该第一投影处理指令设置为指示投影器执行预定的投影处理。
通过上述步骤，根据终端的第一操作信号，找到与该第一操作信号对应的第一投影处理指令并发送给投影器，实现对投影器的投影处理，解决需直接触控投影器或者利用遥控器或激光笔对投影器进行操作而导致的操作不便的技术问题，达到了操作简便的效果，提高了用户的体验度。
步骤S104有多种实现方式，例如，可以将检测到的第一操作信号进行处理，根据算法计算，得到第一投影处理指令，本文中，该步骤S104可以包括：根据操作信号与投影处理指令之间的预定对应关系，以及第一操作信号，确定与第一操作信号对应的第一投影处理指令；将确定的第一投影处理指令发送给投影器。其中，预定了操作信号与投影处理指令之间的对应关系，不必对第一操作信号进行复杂计算，就可以得到该第一操作信号对应的第一投影处理指令，节省了系统资源，提高了处理效率。其中，操作信号与投影处理指令之间的预定对应关系，是操作信号与投影处理指令之间的对应关系的模型，不特指第一操作信号与第一投影处理指令的对应关系。
随着科技的发展，终端支持的功能越来越多，在利用终端实现对投影器 的处理时，可以实现翻页、指示位置、界面操作、修改投影器中正在投影的幻灯片等，需要将与这些功能对应的第一操作信号进行定义。本文中，上述预定对应关系可以包括以下至少之一：在第一操作信号为按压终端的第一按压信号时，第一投影处理指令为设置为校准投影器所呈现的投影上的光标的校准指令；在第一操作信号为设置为对终端的位置状态进行调整的调整信号时，第一投影处理指令为设置为对投影器上所呈现的投影的光标进行移动的移动指令；在第一操作信号为对终端的屏幕进行滑动的滑动信号或按压终端的第二按压信号时，第一投影处理指令为设置为对投影器所呈现的投影进行翻页的翻页指令。本发明实施例中，预先定义了投影器中的常见操作与终端上的第一操作信号的对应关系，可以实现对投影器的处理指令的快速传递、缩短了通过终端对投影器进行处理的处理时间。
上述各个实施例中动作的执行者可以是终端(例如智能手机、平板等)。
在本实施例中还提供了一种投影处理方法，图2是根据本发明实施例的投影处理方法的流程图二，如图2所示，该流程包括如下步骤：
步骤S202，接收终端发送的第一投影处理指令，其中，该第一投影处理指令为终端根据检测到的设置为对终端进行操作的第一操作信号确定的；
步骤S204，根据所述第一投影处理指令进行预定的投影处理。
通过上述步骤，根据接收到的终端的第一投影处理指令，实现对投影器相应的投影处理，解决了需直接触控或者利用遥控器或激光笔对投影器进行操作而导致的操作不便的技术问题，进而达到了操作简便的效果，提高了用户的体验度。
上述实施例中的第一投影处理指令可以为对投影界面进行处理，如放大或缩小，停止放映或开始、暂停放映等，第一操作信号可以为短时触摸信号(即点触信号)、按压信号(点压信号)、长时触摸信号、长时按压信号或者其组合，第一操作信号与第一投影处理指令可以存在多种对应关系，本文中，步骤S204可以包括以下至少之一：当第一投影处理指令为终端根据接收到的设置为按压终端的第一按压信号确定的校准指令时，根据校准指令对投影器所呈现的投影上的光标的位置进行校准；当第一投影处理指令为终端根据接收到的设置为对终端的位置状态进行调整的调整信号确定的移动指令 时，根据移动指令以及终端的位置状态调整数据对投影器所呈现的投影上的光标进行移动；当第一投影处理指令为终端根据接收到的滑动终端的屏幕的滑动信号或按压终端的第二按压信号确定的翻页指令时，根据翻页指令对投影器所呈现的投影进行翻页。其中，给出了终端的第一操作信号与第一投影指令的对应关系，可以快速对投影进行相应的处理。
本文中，在根据移动指令以及终端的位置状态调整数据对投影器所呈现的投影上的光标进行移动之前，还可以包括：存储终端的位置与光标的位置的对应关系。这样，当终端移动到第一位置时，由终端将位置数据传递给投影器，可以使投影器根据预先存储的该对应关系，对投影器上的光标的位置进行调整。由终端代替鼠标，可以避免携带鼠标的情况下对投影器的投影状态进行处理，例如，指示位置。
本文中，在根据移动指令以及终端的位置状态调整数据对投影器所呈现的投影上的光标进行移动之后，还可以包括：确定光标在投影上的预定区域停留的时间超过预定阈值；执行与预定区域对应的功能。例如，在投影的区域中存在功能按键，如向前翻页、向后翻页、停止放映、暂停放映、定位到放映指定页等，当光标在投影的功能按键上停留的时间超过指定阈值(可以为3s)，认为对该功能按键进行了点击，执行该功能按键的对应功能。本发明实施例中，通过终端可以实现了鼠标对投影器的各种功能控制，在终端为用户日常携带的用品的情况下，可以避免对鼠标的携带，提高了用户的体验度。
图2及与图2相关的实施例中的动作的执行者可以是投影器(例如智能微型投影器、其他支持近程通讯的投影器)。
在上述实施例中，终端(如智能手机)几乎每个人都有，利用手机等电子设备来实现激光笔的画面指示功能，以及胶片翻页功能，就能减少携带激光笔及遥控器的麻烦，给用户使用投影器，如微投，提供方便。此外，终端还具备更强大的功能，可以实现界面操作，替换微投外接鼠标。
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根据上述实施例的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 发明实施例的技术方案本质上或者说对现有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设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明实施例各个实施例所述的方法。

下面结合具体的使用场景，对本发明实施例的终端作为鼠标的实现方法进行描述。同样，该实施例也是以手机作为终端为例进行说明的，在该实施例中，将终端作为鼠标的实现方法设计为一个手机应用程序，只要打开该应用程序，就可以调整手机作为鼠标。
用户打开微投，启用用户手机上的该应用程序，使手机与微投建立链接。用户将手机听筒端对准微投屏幕中心(即图10中的OA线指向微投的屏幕中心)，按下侧键“+”和侧键“-”，进行位置校准。
应用程序获得校准数据，即图10中∠GOA和∠NOB的角度度数。图11是根据本发明实施例微投、手机和投影屏幕的垂直方向位置关系图，如图11所示，D1为作为鼠标的手机，D2为微投，A为微投屏幕的垂直方向中点。应用程序默认校准时手机距离微投屏幕距离L1为3米，微投屏幕中心比校准时手机的位置高H1为0.5米，用H1(在图11中没有示出)表示。当然如用户校准位置时，如果实际值L1、H1与默认值相差较大，用户可以在应用程序界面进行调整。手机通过校准，在校准点获得了与微投屏幕的相对位置数据，即测量值∠GOA、∠NOB、和默认值或用户修改值L1、H1。在手机校准界面，还包括了微投与屏幕的距离值L2(在图11中没有示出)，默认值为2米，以及屏幕中心点与微投的高度差H2，默认值为0.4米。同样，如L2和H2与实际投影环境差距太大，用户可以手动调整。完成后手机自动将这些数据发送给微投，这些数据包括测量值∠GOA、∠NOB、和默认值或用户修改值L1、H1、L2、H2。
如图11所示，手机启动应用程序，手机与微投互联，用户在微投周边的某个位置点按校准按钮，手机进入校准状态，用户将手机听筒侧面对准A点，按之前分析，此时可获得∠GOA的角度，微投在屏幕中心显示光标，用户将手指移开校准按钮，校准完成。
因某种原因，用户需将光标上移指示屏幕上的某目标，例如A1，则用户调整手机角度向上指向A1，手机可以侦测到∠GOA1，已知前校准角度∠GOA，∠AOA1＝∠GOA1-∠GOA。手机将与校准时的角度变化的数据∠AOA1传递给微投，微投收到数据∠AOA1后，以A点为基础调光标位置，需要按用户意图，将光标调整到A1点。即需要将∠APA1，调整为与变量∠AOA1对应的角度。
图12是根据本发明实施例的∠APA1、∠AOA1的对应关系分析图，为进一步简化计算公式，在此排除了误差，畸变等的微小的干扰因素，并假设手机高度与微投高度一样。在实际使用过程中，这些因素对手机指向变化与光标移动的影响不太，可以忽略。
如图12所示，假如手机校准点D1的位置就在微投D2的位置，即L1等于L2，用户需将A点的光标移动到A1点，手机向上转动的增量角度∠AOA1，在微投上的光标对应增量角度∠APA1，此时三角形AOA1和APA1是重合的，显然∠AOA1＝∠APA1。如手机校准点D1的位置与屏幕的距离L1为2倍的L2，即L1＝2*L2。
根据边与角的三角函数关系，已知∠AOA1，L1，L2，就可以计算出∠APA1：
tan∠AOA1＝AA1/L1,AA1＝L1*tan∠AOA1
tan∠APA1＝AA1/L2
tan∠APA1＝(L1*tan∠AOA1)/L2
∠APA1＝arctan((L1*tan∠AOA1)/L2)
即已知∠AOA1(用户以校准点为基础，转动手机的角度)、L1、L2，就能获得∠APA1的角度，微投根据∠APA1的角度就能将光标调整到A1位置。
同理，可以推论出对于水平方向上的调整角度。依据用户手机水平转动的角度，微投就能获得光标水平方向的调整角度，图13是根据本发明实施例的∠BOB1、∠BPB1的对应关系分析图，如图13所示，校准时获得∠NOB角度，用户手机水平转动需将光标移动到B1，指南针模块侦测出的角度∠NOB1，那么∠BOB1＝∠NOB1-∠NOB。按照边与角的三角函数关系，可以得出∠BPB1的角度。这样微投根据∠BPB1的角度就能将光标调整到B1位置。
图14是根据本发明实施例终端调整微投投影状态的流程图，如图14所示，该流程包括：
步骤S1402：初始化各模块，预置默认参数，启动应用，连接微投；
步骤S1404：监听侧键输入，等待校准；
步骤S1406：判断接收到的数据是否为校准数据，如果不是校准数据，返回步骤S1404继续等待校准；
步骤S1408：如侦测到启动校准，读取重力加速度模块，指南针模块，L1，L2数据，完成校准，并传送给微投；
步骤S1410：继续侦测数据，等待数据输入；
步骤S1412：判断是否侦测到数据，即数据是否发生变化，在数据没有发生变化的情况下，返回步骤S1410继续侦测数据；
步骤S1414：如有新的数据输入，如判断是否为校准数据(侧键“+”“-”一起压下)，并在判断结果为是校准数据的情况下，将数据标志为校准数据后，返回步骤S1408进行校准，传递校准数据给微投(微投将光标移到投影屏中心)；
步骤S1416：在判断结果为侦测到的数据是用户转动手机的转动数据的情况下，将数据标注为转动数据后，将水平变量角度，垂直变量角度传递给微投；
步骤S1418：微投获得变量数据即校准数据和转动数据，调整光标位置；
步骤S1420：判断是否接收到退出应用程序的指令，如果没有，则返回步骤S1410继续侦测数据；如果是，则继续步骤S1422；
步骤S1422：如手机侦测到用户需退出应用，按用户指令执行退出系列操作，结束。
图15是根据本发明实施例微投根据终端信号调整投影状态的流程图，如图15所示，该流程包括：
步骤S1502：初始化各模块，预置默认参数，启动应用，连接手机；
步骤S1504：监听手机侧数据输入及微投界面输入；
步骤S1506：监听手机侧是否有数据输入，在没有数据输入的情况下，返回步骤S1504继续等待数据输入；
步骤S1508：判断接收到的数据否为校准数据；
步骤S1510：在接收到的数据为校准数据的情况下，将光标调整到投影屏中心；
步骤S1512：在接收到的数据为新增角度的转动数据的情况下，将光标依据手机侧传来的水平分量、垂直分量，调整光标；
步骤S1514：判断是否接收到退出指令，在判断结果为否的情况下，返回步骤S1504继续侦测数据；在判断结果为是的情况下，继续步骤S1516；
步骤S1516：如手机侦测到用户需退出应用，按用户指令执行退出系列操作，结束操作。
根据上述各个实施例及优选实施例，在用户都有手机时，可以利用手机实现类似鼠标的功能，用来替换激光笔、遥控器、和鼠标，给用户使用微投带来极大的方便。
例如，用户手机启动应用，启动微投，选定座位后，用户手指一起按侧键“+”和侧键“-”，并指向微投屏幕中心，进入校准状态。微投收到校准信息后，将光标调整到屏幕中心，完成校准。用户左右，上下转动手机，屏幕上的光标也随之变换。
如果用户因当前位置与之前的校准位置转移较大，使用时手机指向与光标变化无法对准，可以按侧键重新快速校准。如发现转动手机后，对应的投影屏幕光标移动过于灵敏，或不够灵敏，可以手动调整L1，或L2数值，来实现光标灵敏度调整。
该应用扩展更多的功能，如侧键“+”为微投胶片向前翻页，侧键“-”为向后翻页。以及光标停留在投影屏按钮处一定时间，就可以实现按下按钮的功能。以及扩展为将光标停留在投影屏中文字输入框，利用手机就可以输入文字等功能。
又例如，在有多人使用微投环境，可以让其他人的手机也成为鼠标，这样在讨论时，不需要将一个手机互相传递作为鼠标。每个人只要有手机就会实现鼠标功能。只需在每个需加入的手机校准时，有微投分配编码，进行统一管理。当用户将手机放在桌面上不动时，该用户的手机鼠标功能暂时休眠。当用户的听筒端的顶部面不是对着投影屏幕时，该用户的手机鼠标光标不会出现在屏幕上。
通过本发明实施例所述的终端对微投的投影状态进行调整的方法及装置，突出充分利用终端的性能(比如，终端中固有的传感器)来替换激光笔、遥控器、专用鼠标等，避免了用户携带激光笔、遥控器、专用鼠标等，为用户使用微投带来极大方便。
