发明实施例
本发明的实施方式
[0063] 为了能够更清楚地理解本发明的上述目的、 特征和优点, 下面结合附图和具体 实施例对本发明进行详细描述。 需要说明的是, 在不冲突的情况下, 本申请的 实施例及实施例中的特征可以相互组合。
[0064] 在下面的描述中阐述了很多具体细节以便于充分理解本发明, 所描述的实施例 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做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。
[0065] 除非另有定义, 本文所使用的所有的技术和科学术语与属于本发明的技术领域 的技术人员通常理解的含义相同。 本文中在本发明的说明书中所使用的术语只 是为了描述具体的实施例的目的, 不是旨在于限制本发明。
[0066] 图 1为本发明第一实施方式提供的投影画面的校正方法的示意流程图, 所述投 影画面的校正方法可应用于终端中, 用于给投影设备的投影画面进行校正, 其 中, 本发明所指的终端, 可以为智能手机、 智能控制器、 平板电脑、 掌上电脑 、 笔记本电脑、 台式电脑、 车载设备、 导航设备等可以运行应用软件的终端, 在此不作限制, 所述终端可具有屏幕, 所述投影设备可以是投影仪 (包括微型 投影仪) 和激光电视等能够投射投影画面的设备。
[0067] 如图 1所示, 本实施方式的投影画面的校正方法可包括以下步骤:
[0068] 8101: 若终端与投影设备建立连接, 控制在所述终端屏幕上显示至少一预设图 标, 其中, 所述预设图标分别与所述投影设备所投射的投影画面的待校正位置 相对应。
[0069] 投影设备首先向投影墙面或者投影布上投射一投影画面, 投影画面在正常情况 下的形状包括但不限于: 长方形、 正方形等矩形结构、 其他多边形、 以及圆形 或者椭圆形等结构, 待校正位置可以包括多边形的角, 有时可能因为投影设备 \¥0 2019/119621 卩(:17 \2018/074740 摆放不水平或者投影墙面不平整的因素, 导致投影画面为非正常形状, 例如矩 形的投影画面有至少一个角为非 90度 (为锐角或者钝角) , 需要将其校正为正 常的 90度。
[0070] 终端先与投影设备建立连接, 以便于终端能够在后续校正过程中发送调整控制 信息给投影设备, 连接方式可以通过无线方式连接, 例如蓝牙连接或者将终端 和投影设备连入同一个 正1, 也可以是通过有线连接。
[0071] 本步骤中, 所述预设图标可以是圆形触控图标或者其他形式的图标, 可在所述 终端上显示一个或者多个预设图标, 每个预设图标对应投影画面的一个待校正 位置。
[0072] 作为一种可能的实施方式中, 终端可有四个预设图标, 如图 2所示, 分别为预 设图标八、 预设图标:8、 预设图标(:、 预设图标0 , 投影画面可能的待校正位置分 别为 15、 、 (1, 例如, 将矩形投影画面的四个角位置作为可能的待校正位置, 四个预设图标分别对应投影画面的四个角位置, 四个角依次为 15、 、 (1, 分别 位于投影画面的左上角、 右上角、 右下角、 左下角, 其中预设图标八对应 &的位 置, 预设图标:8对应 15的位置, 预设图标(:对应〇的位置以及预设图标 0对应(1的位 置。 可以理解的是, 终端可以设不同个数的预设图标以对应需要校正或者可能 需要校正的位置, 例如还可以将椭圆形投影画面的在长轴以及短轴的两端作为 待校正位置。
[0073] 当预设图标为多个时, 预设图标的分布位置不限定, 例如, 一实施方式中, 如 图 2所示, 多个预设图标之间的依次连接所形成的形成与投影画面的形状相同, 如为矩形结构, 预设图标八、 :8、 (:、 0分别位于屏幕中左上方、 右上方、 右下方 和左下方, 另一实施方式中, 如图 3所示, 多个预设图标沿着直线 (包括沿着终 端屏幕短边方向形成的直线以及沿着终端屏幕长边方向形成的直线, 或者其他 直线结构) 分布, 当预设图标以直线式分布时, 可在屏幕上显示校正提示信息 , 校正提示信息可以用于提示每个预设图标分别是用于校正投影画面的具体位 置的信息, 例如预设图标八用于校正矩形投影屏幕左上角位置, 预设图标:8用于 校正矩形投影屏幕右上角位置, 等。
[0074] 本实施方式中, 当预设图标为多个时, 例如为四个时, 四个预设图标之间可以 \¥0 2019/119621 卩(:17 \2018/074740 围成矩形的显示界面, 显示界面的形成可与投影画面在正常情况下的形状相同 , 显示界面内可显示画面, 所述画面可以是与投影画面的内容相同的画面, 终 端在与投影设备建立连接后, 投影设备可以将当前所投射的投影画面的内容发 送给终端, 终端接收到投影画面的内容后在显示界面内显示, 或者, 终端将显 示界面所显示的画面发送至投影设备进行投射, 因此, 可方便于用户在终端通 过观看与投影画面的内容相同的画面来进行校正, 提高校正的准确性以及提高 用户体验。
[0075] 8102: 根据获取到的在所述预设图标的触控操作生成调整控制信息。
[0076] 所述触控操作包括滑动操作、 拖动操作、 点击操作、 按压操作等控制操作。
[0077] 本实施方式中, 可以是针对每个预设图标的实时触控操作生成相应的调整控制 信息, 终端持续获取到针对预设图标的触控操作, 终端根据持续获取到的所述 触控操作生成持续的调整控制信息, 终端将该预设图标对应的调整控制信息实 时发送给投影设备, 投影设备可实时接收调整控制信息, 例如, 用户在对预设 图标八进行拖动操作时, 终端实时获取针对预设图标八的拖动距离和方向, 生成 相应的调整控制信息发送个投影设备, 实时校正投影画面的待校正位置, 例如 , 当预设图标 向左移动一个像素, 即生成相应的调整控制信息, 当预设图标八 再继续向上移动一个像素, 又生成相应的调整控制信息。
[0078] 本实施方式还可以是针对一个预设图标的触控操作完毕后生成相应的调整信息 , 或者针对多个预设图标的触控操作后生成相应的调整信息, 例如, 终端在获 取针对至少一所述预设图标的触控操作, 根据所述触控操作生成包括整体调整 方案的控制信息, 例如用户在对预设图标八和预设图标:8分别或者同时进行拖动 操作时, 当预设图标八和/或预设图标:8拖动确定完毕后, 生成整体调整方案后, 将控制信息发送给投影设备, 整体校正投影画面的待校正位置, 例如当预设图 标八向左移动一个像素后, 不立即生成调整控制信息, 当预设图标八继续向右移 动一个像素并确定完毕后, 立即生成调整控制信息; 或者, 当预设图标整体移 动完毕后, 生成整体调整方案的控制信息。
[0079] 8103: 根据所述调整控制信息对所述投影设备的工作参数进行调整, 以校正所 述投影画面的待校正位置。 \¥0 2019/119621 卩(:17 \2018/074740
[0080] 投影设备在不同的工作参数下工作时, 所投射出的投影画面的形状会有所不同 , 例如投射的形状或者角度值不同等, 通过调整投影设备的工作参数, 可以达 到校正投影画面的待校正位置的目的。
[0081] 所述调整控制信息可以包括角度校正值, 投影设备根据接收到的调整控制信息 调整工作参数, 例如当预设图标八在拖动时, 可以根据预设图标拖动后的位置以 及原始位置计算出预设图标所拖动的距离和方向, 相应地调整投影设备的工作 参数, 在调整后的工作参数工作下的投影设备, 能够校正相应待校正位置的角 度值, 例如矩形投影画面达到正常情况时的 90度, 投影画面的边缘线符合椭圆 弧线等。
[0082] 本实施方式中, 可以根据接收到的针对预设图标的调整信息来相应的调整待校 正位置的像素值, 例如, 可以以预设的调整方式来进行调整, 如将预设图标拖 拽一个单位距离, 则待校正位置调整 1个像素, 也可以是点击一次或者拖拽一个 单位距离, 待校正位置调整 10个像素。
[0083] 本实施方式中, 还可以先控制投影设备将投影画面进行缩放, 再根据接收到的 针对预设图标的调整信息来相应的调整待校正位置的像素值, 最后将投影画面 尺寸恢复到所希望的大小。 如此, 可相应增加或者减小待校正位置所需要校正 的像素值, 方便于精确校正、 快速校正。 如当待校正位置需要大幅度校正时, 可以先控制投影设备将投影画面进行缩小, 将预设图标拖拽一个单位距离, 校 正的幅度相对于未缩小时而言, 校正速度会更快, 得以快速校正; 而当待校正 位置需要精确校正时, 可以先控制投影设备将投影画面进行放大, 将预设图标 拖拽一个单位距离, 校正的幅度相对于未放大时而言, 校正速度会更慢, 得以 精确校正。
[0084] 本实施方式所提供的投影画面的校正方法, 在所述终端的屏幕上显示至少一预 设图标, 其中, 所述预设图标分别与所述投影设备所投射的投影画面的待校正 位置相对应, 根据获取到的在所述预设图标的触控操作生成调整控制信息, 根 据所述调整控制信息对所述投影设备的工作参数进行调整, 以校正所述投影画 面的待校正位置。 本实施方式能够通过触控终端的预设图标来调整投影设备的 工作参数, 实现投影画面的待校正的目的, 能够有效提高投影画面的校正效率 \¥0 2019/119621 卩(:17 \2018/074740 提高用户体验。
[0085] 图 4为本发明第二实施方式提供的投影画面的校正方法的示意流程图。 所述第 二实施方式与第一实施方式的主要区别在于, 第二实施方式中包括生成调整控 制信息的具体步骤。 需要说明的是, 在本发明的精神或基本特征的范围内, 适 用于第一实施方式中的各具体方案也可以相应的适用于第二实施方式中, 为节 省篇幅及避免重复起见, 在此就不再赘述。
[0086] 本实施方式的具体方法步骤如下:
[0087] 8201: 若终端与投影设备建立连接, 控制在所述终端屏幕上显示至少一预设图 标, 其中, 所述预设图标分别与所述投影设备所投射的投影画面的待校正位置 相对应。
[0088] 8202: 判断是否获取到针对一所述预设图标的选中操作, 若是, 则执行步骤 32
03 , 若否, 则继续执行本步骤或者直接结束流程。
[0089] 当终端的屏幕上显示有预设图标时, 可以在预设图标上, 通过点击或者按压来 选中该预设图标。
[0090] 8203: 在所述预设图标上显示控制图标。
[0091] 在判断到有针对一所述预设图标的选中操作时, 在预设图标上显示控制图标, 如图 5和图 6所示, 显示方式可以是弹出控制图标界面, 或者可以是在预设图标 的基础上延伸出控制图标, 其中, 所述控制图标可以是箭头图标, 如图 5所示, 可以包括上、 下、 左、 右等方向的箭头, 每一方向箭头均是触控点, 所述控制 图标还可以是转动盘结构, 如图 6所示。
[0092] 8204: 根据获取到的在所述控制图标的触控操作生成与所述待校正位置相对应 的调整控制信息。
[0093] 例如, 可根据在箭头图标的方向箭头上的触控操作 (包括点击或者按压等操作 ) 得到相应的调整控制信息, 如图 5所示, 用户在向上的方向箭头上相应调整了 10个像素, 接着在向左的方向箭头上相应调整了 20个像素, 终端可以在用户每 调整一个像素, 即生成调整控制信息, 投影设备在该方向上相应调整一个像素 , 也可以在针对该预设图标的触控操作完毕后再生成调整控制信息, 投影设备 再一次性相应调整。 \¥0 2019/119621 卩(:17 \2018/074740
[0094] 本实施方式中, 也可以是针对一个控制图标的触控操作完毕后生成相应的调整 信息, 或者针对多个控制图标的触控操作后生成相应的调整信息。
[0095] 还可以根据在转动盘的触摸时间以及触摸时所滑动的方向来得到调整控制信息 , 如图 6所示, 用户在转动盘上的往一个方向滑动的时间为 18 , 则投影设备在该 方向上按照预设调整个数相应调整像素。
[0096] 8205: 根据所述调整控制信息对所述投影设备的工作参数进行调整, 以校正所 述投影画面的待校正位置。
[0097] 本实施方式除了具有第一实施方式的有益效果之外, 包括生成调整控制信息的 具体步骤, 在所述终端的屏幕上显示至少一预设图标, 其中, 所述预设图标分 别与所述投影设备所投射的投影画面的待校正位置相对应, 判断是否获取到针 对一所述预设图标的选中操作, 若是, 则在所述预设图标上显示控制图标, 根 据获取到的在所述控制图标的触控操作生成与所述待校正位置相对应的调整信 息, 根据所述调整控制信息对所述投影设备的工作参数进行调整, 以校正所述 投影画面的待校正位置, 因此, 本实施方式先对预设图标进行选取, 选取之后 再进行操作, 如此可避免在对预设图标进行操作时触碰到其他预设图标而使得 投影设备校正投影画面无需校正的位置。

[0099] 本实施方式的具体方法步骤如下:
[0100] 8301: 若终端与投影设备建立连接, 控制在所述终端屏幕上显示至少一预设图 标, 其中, 所述预设图标分别与所述投影设备所投射的投影画面的待校正位置 相对应。
[0101] 8302: 根据获取到的对所述预设图标的拖动操作确定所述预设图标的移动信息
[0102] 如图 8所示, 可以将一预设图标的原始位置作为十字平面坐标系的原点, 当该 \¥0 2019/119621 卩(:17 \2018/074740 预设图标拖动至一位置时, 得到该位置的坐标 (x, y) , 该预设图标在 x、 y方 向上的移动向量为 (x, y) ; 或者可以将屏幕的中心或者多个预设图标所围成 的形状的中心作为十字平面坐标系的原点, 一预设图标的原始位置为 (x〇, y〇 ) , 当该预设图标拖动至一位置时, 得到该位置的坐标为 (xl, yl) , 通过计 算可以得到该预设图标在 x、 y方向上的移动向量为 (xl- xO, yl- yO) 。
[0103] 本实施方式中, 也可以是针对一个预设图标的拖动操作完毕后生成相应的调整 信息, 或者针对多个控制图标的拖动操作后生成相应的调整信息。
[0104] S303: 根据所述移动信息生成与所述待校正位置相对应的调整控制信息。
[0105] 根据得到的移动信息, 可得到相应方向所要调整的素值, 例如, 一预设图标拖 动至第二象限的坐标值为 (-10,20) 时, 可相应地表示需要将待校正位置在原来 的基础上向左调整 10个像素以及向上调整 20个像素, 以使得投影画面的待校正 位置校正完毕后, 投影画面为正常形状。
[0106] S304: 根据所述调整控制信息对所述投影设备的工作参数进行调整, 以校正所 述投影画面的待校正位置。
[0107] 本实施方式除了具有第一实施方式的有益效果之外, 还包括预设图标, 在所述 终端的屏幕上显示至少一预设图标, 其中, 所述预设图标分别与所述投影设备 所投射的投影画面的待校正位置相对应, 根据获取到的对所述预设图标的拖动 操作确定所述预设图标的移动信息, 根据所述移动信息生成与所述待校正位置 相对应的调整控制信息, 根据所述调整控制信息对所述投影设备的工作参数进 行调整, 以校正所述投影画面的待校正位置, 因此, 本实施方式能够方便于用 户调整预设图标的位置来实现校正投影画面的待校正位置。
