本申请提供了一种按键映射方法，该方法可以应用于本申请所提供的电子设备上。其中，电子设备可以为手机、平板电脑、个人计算机(personalcomputer，PC)、智能电视等电子设备，本申请对电子设备的具体类型不作任何限制。该方法可以将电子设备上应用程序中的虚拟按键元素与外设电子设备(例如外设手柄)的物理按键(又可称为实体按键)建立映射关系，然后用户可以使用外设电子设备操控该应用的按键，以触发该按键对应的功能。例如，以游戏应用为例，由于游戏应用中的按键区域相对于游戏画面是分离的，也即是说，该按键区域不会随着游戏画面的变化而产生改变。并且，该按键区域与区域周边游戏画面的颜色存在着较大的反差。因此，根据本申请实施例中的方法，电子设备可以通过图像处理算法识别出游戏应用中的按键区域。另外，为了提高按键区域识别的精度，电子设备还可以结合用户对于该游戏画面的触控频率，对该图像处理算法进行校正。在识别出所有的按键区域后，对每一个按键区域进行编号，同时，电子设备界面上可以出现用户可以控制移动的光标，该光标可以在识别出的按键区域范围内进行移动。用户可以通过控制该光标在识别出的按键区域上的移动操作，从而在应用界面中选择出需要跟游戏手柄的物理按键进行匹配的虚拟按键图标。比如，在光标停留在第一游戏虚拟按键的时候，用户可以按下游戏手柄上的第一物理按键，这样第一物理按键与第一游戏虚拟按键建立映射关系。当用户将游戏应用中所有的虚拟按键图标与游戏手柄的物理按键一一进行匹配后，映射关系建立完成，用户可以通过控制游戏手柄上的物理按键来触发游戏应用中的虚拟按键，进而触发虚拟按键对应的功能，比如游戏中人物的移动、技能的施放、场景的切换等等。
与现有技术相比，实施本申请的技术方案，可以在减少在游戏手柄与游戏应用按键匹配过程中用户操作的步骤，使得用户操作更加简便，匹配更为精确，大大提升了用户的使用体验。
下面，介绍一些与本申请相关的术语及概念。
用户界面(user interface，UI)是应用程序或操作系统与用户之间进行交互和信息交换的介质接口，它实现信息的内部形式与用户可以接受形式之间的转换。应用程序的用户界面是通过java、可扩展标记语言(extensible markup language，XML)等特定计算机语言编写的源代码，界面源代码在终端设备上经过解析、渲染，最终呈现为用户可以识别的内容，比如图片、文字、按钮等控件。
无符号整数在计算机的二进制计数中，最左边一位不用来表示正负，而是和后面的连在一起表示整数，那么就不能区分这个数是正还是负，就只能是正数，这就是无符号整数。
灰度是指使用黑色调表示物体，即用黑色为基准色，不同的饱和度的黑色来显示图像。每个灰度对象都具有从0％(白色)到灰度条100％(黑色)的亮度值。
噪声是指图像中表现极为突兀的像素点或像素块，会给图像带来干扰没让图像变得不清楚，或者说影响观察图像的细节。
高斯噪声是指噪声像素的概率密度函数服从高斯分布(也称作正态分布)。也即是说，如果一个噪声，它的幅度服从高斯分布，而它的功率谱密度优势均匀分布的，则称为高斯噪声。
高斯滤波是一种线性平滑滤波，适用于消除高斯噪声，广泛应用于图像处理的减噪过程。通俗地讲，高斯滤波就是对整幅图像进行加权平均的过程。每一个像素点的值，都由其本身和邻域内的其他像素值经过加权平均后得到。高斯滤波的具体操作是用一个模板(或称高斯核)扫描图像中的每一个像素，用模板确定的邻域内像素的加权平均灰度值去代替模板中心的值。高斯滤波器对于一直服从正态分布的噪声非常有效。
RGB是指代表红(red，R)、绿(green，G)、蓝(blue，B)三个通道的颜色，电子设备是通过对上述三个颜色通道的变化以及它们相互之间的叠加来得到各式各样的颜色。这种颜色表示的标准几乎包括了人类视力所能感知的所有颜色，是目前运用最广泛的颜色系统之一。
模糊半径是指在高斯滤波过程中，某个像素点向外扩展的值。
梯度是指在向量微积分中，标量场中某一点上的梯度指向标量场增长最快的方向，梯度强度是这个方向上最大的变化率。在单变量的实值函数的情况下，梯度只是导数，或者，对于一个线性函数来说，梯度也就是线的斜率。用于斜度，也就是一个曲面沿着给定方向的倾斜程度，梯度的数值有时也被称为梯度。

可以理解的是，提示信息621、重新识别图标622、建立游戏手柄按键映射图标623独立于游戏应用的用户界面，也即是说，上述提示信息与图标并不与游戏应用的用户界面相关，当游戏应用的用户界面发生改变时，上述提示信息与图标并不随之发生改变。
图13示出了一个实施例中，电子设备100与电子设备200建立按键映射的实施过程的界面示意图。
如图13所示，响应于作用在建立游戏手柄按键映射图标623上的触控作用(例如点击)，开始建立电子设备100与电子设备200的按键映射时，电子设备100可以显示出用户界面63。当游戏虚拟按键与游戏手柄物理按键建立映射关系时，用户界面63中显示出可以供用户可操控的光标图标631。该光标图标631可以用于在已经识别出的按键区域上移动，当需要对某个虚拟按键进行适配时，用户将光标移动到该指定虚拟按键图标上，使得该光标悬停在该虚拟按键图标上。
例如，如图13所示，该光标图标631悬停在已被标识为高亮的普攻技能按键625C上。当响应于作用在电子设备200上功能按键201E的触控操作(例如按压)，电子设备200向电子设备100发送包含有功能按键201E键值的第一信号。当响应于接收到包含有功能按键201E键值的第一信号时，电子设备100建立普攻技能按键625C与功能按键201E的映射关系，该普攻技能按键625C不再高亮显示。电子设备100完成普攻技能按键625C与功能按键201E的映射后，电子设备100显示出用户界面64。该用户界面64中，光标图标631移动到下一个被标记成为高亮的方向按键区域624。检测到电子设备200作用于摇杆按键201A的触控操作(例如按压)，电子设备100建立方向按键区域624与摇杆按键201A的映射关系，该方向按键区域624不再高亮显示。当所有按键都与电子设备200建立映射关系后，电子设备100显示出光标图标631消失，所有按键都不再高亮显示的用户界面65。
在一些实施例中，光标图标631可以自行移动到高亮按键区域，也可以由用户操控移动至用户所指定的高亮按键区域，本申请对此不作限制。
在另一些实施例中，电子设备100可以对按键映射进行合法性检测，也即是说，当用户在建立按键映射关系的过程中，响应于作用于电子设备200上的物理按键的触控操作(例如按压)，电子设备200向电子设备100发送包含有物理按键键值的第一信号，当电子设备100接收到包含有该物理按键键值的第一信号时，会检测该物理按键键值是否已与电子设备100上的其他虚拟按键图标建立了映射关系。若是，则显示出提示信息以提示用户该物理按键已与其他虚拟按键图标建立映射。该提示信息可以是文本信息，例如“该按键已建立映射，请重新进行选择”，也可以是语音信息，本申请对此不作限制。
具体的，例如，如图13所示，电子设备100上的普攻技能按键625C已与电子设备200上的功能按键201E已经建立了映射关系，此时，光标图标631移动至还未进行按键映射的方向按键区域631，若响应于作用于电子设备200上的功能按键201E的触控操作(例如按压)，电子设备200向电子设备100发送包含有功能按键201E键值的第一信号，当电子设备100接收到包含有功能按键201E键值的第一信号时，检测到该功能按键201E键值已与普攻技能按键625C建立映射关系，则显示出文本提示信息“该按键已建立映射，请重新进行选择”，以提示用户该物理按键已与虚拟按键图标建立映射。
在另一些实施例中，电子设备100还可以对按键映射进行合理性检测，也即是说，当用户在建立按键映射关系的过程中，响应于作用于电子设备200上的物理按键的触控操作(例如按压)，电子设备200向电子设备100发送包含有物理按键键值的第一信号，当电子设备100接收到包含有该物理按键键值的第一信号时，会检测该物理按键键值是否能与该选定的虚拟按键图标建立正确的映射关系。若否，则显示出提示信息以提示用户重新进行选择。该提示信息可以是文本信息，例如“该按键不能与选定按键图标进行匹配，请重新进行选择”，也可以是语音信息，本申请对此不作限制。
具体的，例如，如图13所示，光标图标631移动至还未进行按键映射的方向按键区域631，若响应于作用于电子设备200上的功能按键201E的触控操作(例如按压)，电子设备200向电子设备100发送包含有功能按键201E键值的第一信号，当电子设备100接收到包含有功能按键201E键值的第一信号时，检测到该功能按键201E键值不能与方向按键区域631建立正确的映射关系，则显示出文本提示信息“该按键不能与选定按键图标进行匹配，请重新进行选择”，以提示用户重新选择可以与方向按键区域631进行正确映射的物理按键(例如摇杆按键201A)。
图14A、图14B示出了电子设备100与电子设备200成功建立按键映射后的游戏手柄控制游戏应用中应用按键所产生的效果界面示意图。
当电子设备100上的虚拟按键图标与电子设备200上的物理按键建立映射关系后，响应于用户作用在电子设备200上物理按键的触控操作(例如按压)，电子设备100可以显示出新的用户界面(又可称为第二用户界面)，该用户界面可以部分或全部不同于未触控电子设备200上的物理按键时电子设备100所显示的用户界面，例如游戏应用界面的跳转、游戏应用界面中人物的移动、游戏场景的改变等等导致的用户界面的刷新。具体的，如图14A、图14B示例性示出了本申请上述的技术效果界面。
如图14A所示，电子设备200中的功能按键201E与电子设备100上的“普攻”按键图标625C建立了映射关系。当电子设备100检测用户手指712作用于电子设备200上的功能按键201E的触控操作(例如按压)时，电子设备100即产生该“普攻”按键图标625C的触控事件，电子设备100显示出游戏人物图标601发动普攻技能的用户界面71。
如图14B所示，电子设备200中的摇杆按键201A与电子设备100上的方向按键区域624建立了映射关系。当电子设备100检测用户手指732作用于电子设备200上的摇杆按键201A的触控操作(例如向右推动)时，电子设备100即产生该方向按键区域624中向右方向按键624C的触控事件，电子设备100显示出游戏人物图标601在游戏场景中向右移动的用户界面73。
可以理解的是，本实施例图14A、图14B所示出的技术效果界面仅仅用作解释本申请实施例，并不对本申请构成具体限制。
基于上述示例性实施例及示例性应用场景，下面详细说明电子设备100与电子设备200建立按键映射步骤。
图15示出了本申请所提供的一种按键映射方法的流程图。如图15所示，本申请以电子设备100是手机，电子设备200是游戏手柄为例，详细描述该方法，该方法可以包括：
S101、手机与游戏手柄建立第一连接。
具体的，手机和游戏手柄可以具有蓝牙(BT)模块、WLAN模块中的一项或多项。其中，蓝牙(BT)模块可以提供包括经典蓝牙(蓝牙2.1)或蓝牙低功耗(BLE)中一项或多项蓝牙通信的解决方案。WLAN模块可以提供包括Wi-Fi direct、Wi-Fi LAN或Wi-Fi softAP中一项或多项WLAN通信的解决方案。
手机可以使用蓝牙或WLAN中的一种或多种无线通信技术与游戏手柄建立第一连接。
S102、该手机显示第一用户界面。
具体的，该第一用户界面可以包含多个游戏按键(又可称为游戏控件)，这多个游戏按键中可以包括第一游戏按键(又可称为第一控件)。如图9所示的用户界面60，该用户界面可以包括普攻技能按键603C。
S103、该手机检测到第一用户操作。
具体的，该手机检测到用户请求建立游戏按键映射的第一用户操作，如图12所示的用户作用于游戏识别图标611A的触控操作(例如点击)。
S104、该手机扫描第一用户界面，通过第一图像处理算法，识别出第一用户界面中的多个游戏按键。
如图12所示。具体的，游戏画面中的按键区域相对于游戏画面来说是分离的，也即是说，按键区域不会随着游戏画面的变化而变化，并且，按键区域与周边游戏画面的颜色反差较大。因此，手机可以通过第一图像处理算法，将游戏画面中的按键区域识别出来。然后，为了提高按键区域的识别精准度，手机可以结合获取到的用户在该游戏应用画面中的触控频率，对第一图像处理算法进行校正，从而准确有效地找到游戏画面中的按键区域。
在一些实施例中，第一图像处理算法可以是边缘检测算法，关于边缘检测算法是如何识别游戏按键的，会在后文进行说明，此处先不赘述。
边缘检测算法仅为一个示例，本申请不对第一图像处理算法进行特殊限制，其他可以实现识别游戏按键的方法均可。
S105、在每个游戏按键的位置上生成对应的虚拟按键，即在第一游戏按键的位置上生成第一虚拟按键。
具体的，如图12所示，当手机成功识别出用户界面中的游戏按键位置后，在每个游戏按键的位置上可以生成对应的虚拟按键。
S106、在第一虚拟按键处显示第一光标。
具体的，如图13所示，普攻技能按键625C显示出第一光标631。不限于显示第一光标，第一虚拟按键还可以显示高亮状态、闪烁状态等，只要可以被用户识别为待选定状态即可。
S107、游戏手柄检测到用户按压第一物理按键。
具体的，如图13所示，游戏手柄检测到用户按压第一物理按键功能按键201E的操作。
S108、游戏手柄发送第一物理按键被按压的第一信号。
第一信号可以携带有第一物理按键的标识。
S109、成功建立第一游戏按键和第一物理按键的第一映射关系。同理，其余按键也一一建立映射关系。
具体的，如图13所示，手机可以获取有光标图标631悬停的普攻技能按键625C的位置信息，以及第一物理按键功能按键201E的标识或键值，并形成两者间的映射关系。同理，手机上其余虚拟按键和游戏手柄上的物理按键也一一建立映射关系。
在第一游戏按键与第一物理按键建立完映射关系后，第一光标可以从第一游戏按键处移至第二游戏按键处，本申请对按键匹配时光标移动的顺序不作限制，光标可以移至任意一个还未建立映射的游戏按键处。
在手机界面中的游戏按键与游戏手柄的物理按键建立映射关系后，手机中可以生成并存储有第一映射表，该第一映射表中记录了手机界面中的游戏按键与游戏手柄的物理按键之间的映射关系。
S110、在所有游戏按键与游戏手柄的物理按键的映射关系建立完成之后，手机返回显示第一用户界面。
具体的，当手机上所有游戏按键和游戏手柄上的物理按键的映射关系建立完成后，手机返回显示游戏界面。
S111、游戏手柄检测到用户按压第一物理按键。
如图14A所示，游戏手柄检测到用户按压第一物理按键功能按键201E的操作。
S112、游戏手柄向手机发送第一物理按键被按压的第一信号。
S113、手机接收到第一物理按键被按压的信号，根据第一映射关系，触发第一游戏按键被点击。
S114、手机显示第二用户界面，第二用户界面为第一游戏按键对应的游戏功能被触发所展示的用户界面。
如图14A所示，当游戏手柄上的第一物理按键功能按键201E被按压时，手机接收到第一物理按键功能按键201E被按压的信号，触发点击普攻功能按键625C被点击的事件，显示出对应的普攻技能被触发所展示的用户界面71。
在一些实施例中，电子设备100也可以设置第一时长阈值，当光标悬停在虚拟按键图标上的时间超过第一时长阈值时，电子设备100将该虚拟按键图标确认为需要进行是适配的虚拟按键图标，并获取该虚拟按键图标的位置信息。因此，可以理解的是，对于电子设备100如何确认游戏应用画面中哪个虚拟按键图标是需要进行适配的虚拟按键图标，本申请对此并不作限制。
下面结合图16和图17，以边缘检测算法为例，说明电子设备100识别游戏应用画面中的按键区域的步骤。如图16所示，该方法步骤可以包括：
S201、电子设备100对第一图像进行灰度处理，得到第二图像。
具体的，第一图像是第一用户界面转化的图像，第一用户界面即游戏界面。第一图像为彩色图像，第二图像是第一图像进行灰度处理后得到的灰色图像。
可以理解的是，当前主流的标准图像表示方式是24比特模式，即每像素24位(bitsperpixel，BPP)编码的RGB值。它是使用三个8位无符号整数(0到255)表示红色、绿色和蓝色的强度。24比特模式用于真彩色和联合图像专家小组(joint photographic experts group，JPEG)图像格式或者标签图像文件格式(tag image file format，TIFF)等图像文件格式里的通用颜色交换。它可以产生一千六百万种颜色组合，对人类的眼睛来说，其中有许多颜色已经无法确切地分辨。也即是说，电子设备100先存储红色R(8bit)，再存储绿色G(8bit)，最后存储蓝色B(8bit)，一共24bit，每个颜色256个梯度，交错地以RGBRGBRGB……这样的形式存储在文件里面。其中，JPEG是一个国际图像压缩标准，JPEG图像压缩算法能够在提供良好的压缩性能的同时，具有比较好的重建质量，被广泛应用于图像、视频处理领域。TIFF是一种灵活的位图格式，主要用来存储包括照片和艺术图在内的图像。
而灰度图只有8位的图像深度，因此在图像处理中，灰度图所需的计算量比彩色图的计算量要少。虽然丢失了一些颜色等级，但是从整幅图像的整体和局部的色彩及亮度等级分布特征来看，作为灰度图的第二图像的描述与作为彩色图的第一图像的描述是一致的。
因此，电子设备100可以将第一图像进行灰度处理。根据R、G、B的重要性及其他指标，将三个不同的分量进行加权平均。由于人眼对绿色的敏感度最高，对蓝色的敏感度最低，因此，按公式1中对RGB三个分量进行加权平均能得到较合理的灰度图像。电子设备100可以根据公式1得到第一图像中每一个像素的灰度值，从而获得灰度处理后的第二图像：
Gray＝0.3R+0.6G+0.1B公式1
S202、电子设备100对第二图像进行高斯滤波。
具体的，在本申请实施例中，对第二图像进行高斯滤波处理即是对第二图像的灰度值进行加权平均，也即是说，针对第二图像中每一个像素点的灰度值，都由其本身值和邻域内的其他灰度值经过加权平均，最终得到该像素点经过高斯滤波后的最终灰度值。
因此，可以看出，高斯滤波可以分为两步：1.获取高斯模板(也即是权重模板)。2.进行加权平均。
在像素点的加权平均过程中，正态分布显然是一种可取的权重分配模式，由于图像是二维的，所以需要使用二维的高斯函数，如公式2所示：
Figure PCTCN2021128486-appb-000010
在计算权重时，只需要将“中心点”作为原点，其他点按照其在正态曲线上的位置，分配权重，就可以得到一个加权平均值。
示例性的，假定σ＝1.5，模糊半径为1，中心点的坐标为(0,0)，那么距离它最近的8个点坐标如表1所示：
表1
(-1,1) (0,1) (1,1)
(-1,0) (0,0) (1,0)
(-1,-1) (0,-1) (1,-1)
将上述坐标中的横坐标作为二维高斯函数中的x，纵坐标作为二维高斯函数中的y，经计 算，则模糊半径为1的权重矩阵如表2所示：
表2
0.0453542 0.0566406 0.0453542
0.0566406 0.0707355 0.0566406
0.0453542 0.0566406 0.0453542
这9个点的权重总和等于0.4787147。根据权重模板的特性，如果只计算这9个点的加权平均，还必须让它们的权重之和等于1，因此上面9个值还需要分别除以0.4787147，得到最终的权重矩阵，如表3所示：
表3
0.0947416 0.118318 0.0947416
0.118318 0.147761 0.118318
0.0947416 0.118318 0.0947416
由于本申请示例性的实施例的模糊半径为1，因此，在对像素点进行高斯滤波计算时，只需要取周围8个像素点进行加权平均。示例性的，该9个像素点的灰度值如表4所示。灰度值范围为0-255。位于表4中心的像素点即为本次需要处理的像素点：
表4
14 15 16
24 25 26
34 35 36
将上述表4中像素点的灰度值分别与表3中对应位置的权重相乘，如表5所示：

由于表示灰度值的符号是正整数，因此，可以近似取为25。
由上述本申请示例性实施例可以看出，电子设备100对第一图像中每一个像素点重复上述过程，既可获得第二图像。
在另外一些实施例中，二维高斯函数中的x，y还可以有其他的取值方式，也即是说，最后所得到的权重矩阵也可以是其他数值，本申请对此不作限制。
在另外一些实施例中，第一图像可以不经过灰度化，电子设备100可以直接对第一图像进行高斯滤波。也即是说，电子设备100可以针对第一图像，分别对第一图像中的RGB三个 通道进行高斯滤波。
S203、电子设备100获取用户触控频率。
具体的，以前述的游戏应用程序为例，电子设备100可以获取用户在电子设备100屏幕界面针对于该游戏应用场景下的触控操作(例如点击)的第一次数数据。
具体的，获取用户在电子设备100屏幕界面针对于该游戏应用场景下的触控操作(例如点击)的次数，可以由游戏手柄应用程序进行。该游戏手柄应用程序可以获取到位于电子设备100内部存储空间中的，用户在电子设备100屏幕界面针对于该游戏应用场景下的触控操作(例如点击)的第一次数数据。该第一次数数据可以是用户在电子设备100屏幕界面针对于该游戏应用场景下的触控操作(例如点击)的历史次数数据，也即是说，该第一次数数据可以是该游戏应用还未进行按键识别操作、或按键匹配操作前，用户在电子设备100屏幕界面针对于该游戏应用场景下的触控操作(例如点击)的次数数据。
在一些实施例中，电子设备100可以在电子设备100与电子设备200建立通信连接时获取用户针对需要进行按键匹配的应用的触控频率。在另一些实施例中，电子设备100也可以在对第一图像进行灰度处理后，获取用户针对需要进行按键匹配的应用的触控频率。也即是说，电子设备100获取用户针对需要进行按键匹配的应用的触控频率这一步骤，只需要在电子设备100利用线性插值公式处理边缘检测之前完成，具体发生顺序本申请对此并不做限制。
S204、电子设备100结合上述获取到的用户触控频率，对第二图像进行边缘检测。
具体的，电子设备100利用边缘检测算法对第二图像进行边缘检测。
在本申请实施例中，边缘检测算法的边缘检测算子可以采用Sobel边缘差分算子或其他算子。Sobel边缘差分算子可以根据像素点上下、左右邻点灰度加权差，在边缘处达到极值这一现象来检测边缘。Sobel边缘差分算子计算出水平方向的差分G x、垂直方向的差分G y，由此可以确定像素点的梯度模(也称梯度强度)G和方向θ。如公式3和公式4所示，G为梯度强度(也称为梯度值)，θ表示方向，arctan为反正切函数：
Figure PCTCN2021128486-appb-000011
Figure PCTCN2021128486-appb-000012
如果梯度强度G大于或等于某一阈值，则认为该像素点为边缘点。
下面，示例性地描述如何计算梯度强度G和方向θ。
x和y方向的Sobel算子分别为：
Figure PCTCN2021128486-appb-000013
其中，S x表示x方向的Sobel算子，用于检测y方向的边缘；S y表示y方向的Sobel算子，用于检测x方向的边缘(边缘方向和梯度方向垂直)。
若图像中有一个3x3的窗口为A，要计算梯度的第一像素点为e，则和Sobel算子进行卷积后，第一像素点e在x方向和y方向的梯度值分别为：
Figure PCTCN2021128486-appb-000014
Figure PCTCN2021128486-appb-000015
其中，*为卷积符号，sum表示矩阵中所有元素相加求和。根据公式3和公式4便可以计算出第一像素点e中第一梯度向量的梯度强度和方向。
对图像进行梯度计算后，仅仅基于梯度值提取的边缘仍然很模糊，因此，需要将计算出来的梯度边缘进行边缘细化，也即是说，保留局部最大梯度值，而将其他除局部最大梯度值外的所有梯度值抑制为0。该部分的算法分为两个步骤：1.将当前像素的梯度强度与沿正负方向上的多个像素进行比较。2.如果当前像素的梯度强度与另外几个像素相比最大，则该像素点被保留为边缘点，否则，该像素点将被抑制。通常为了更加精确的计算，在跨越梯度方向的几个相邻像素之间使用线性插值来得到要比较的梯度强度。
示例性的，如图17所示，以5x5窗口为当前第一像素点e的邻近空间，比较当前点像素e的梯度强度T(e)和正负梯度直线相交的窗口上的像素点Q1、Q2、Q3、Q4的梯度强度T(Q1)、T(Q2)、T(Q3)、T(Q4)。其中，S1、S2为与Q1同一条直线上的两点，S3、S4为与Q2同一条直线上的两点，S5、S6为与Q3同一条直线上的两点，S7、S8为与Q4同一条直线上的两点。
如公式5、公式6、公式7所示，计算Q1的梯度强度T(Q1)的线性插值公式为：
Figure PCTCN2021128486-appb-000016
Figure PCTCN2021128486-appb-000017
T(Q1)＝e (w×T(S1)+(1-w)×T(S2))公式7
其中，distance(S1,S2)表示S1、S2两点之间的距离，w系数可以通过梯度方向计算得到。同时，结合用户的使用习惯，对触控频率高的区域增加权重m，n为每分钟当前点S被用户点击的次数，以作为该区域梯度变换的修正值，同理计算其他Q1、Q2、Q3、Q4其他点的梯度强度。
若当前像素点S的梯度强度和同方向的Q1、Q2、Q3、Q4其他点的梯度强度相比较时最大的，保留其值。否则将当前像素点S的梯度抑制，也即是说，将当前像素点S的梯度设置为0。
在上述对梯度边缘进行细化后，剩余的像素可以更准确地表示图像中的实际边缘。然而，图像中仍然存在由于噪声和颜色变化引起的一些边缘像素。为了解决这些杂散响应，必须用弱梯度值过滤边缘像素，并保留具有高梯度值的边缘像素，可以通过选择高低阈值来实现。统计整幅图像所有像素点的梯度强度的直方图，选取占直方图总数75％的所对应的高位梯度强度为高阈值(也可以称为第一阈值)，占直方图中总数25％的所对应的低位梯度强度为低阈值。如果像素点的梯度值高于高阈值，则将该像素保留；如果像素点的梯度值小于低阈值，则该像素点会被排除。
最后，所有识别出的边缘像素点依次连接构成第一图像上按键区域的边界。
在另外一些实施例中，也可以通过其他方法选取高阈值和低阈值的数值，本申请对此不作限制。
S205、电子设备100获取多帧图像，并对每一帧图像重复上述步骤。
具体的，电子设备100可以获取在时间轴上连续的一组图像，并对该组中的每一帧图像重复进行高斯滤波和边缘检测。在另一些实施例中，电子设备100也可以根据一定的时间间隔获取一组图像。可以理解的是，对于电子设备100如何获取多帧图像，本申请对此不作限制。
S206、电子设备100比较多组图像的结果，获取按键区域边缘。
具体的，电子设备100可以获取多组图像进行高斯滤波和边缘检测后的输出结果，并将该结果进行比较。电子设备100可以获取多组图像输出结果比较后的重复识别位置，该重复识别位置即为电子设备100需要获取的按键区域。
上述实施例中，根据上下文，术语“当…时”可以被解释为意思是“如果…”或“在…后”或“响应于确定…”或“响应于检测到…”。类似地，根据上下文，短语“在确定…时”或“如果检测到(所陈述的条件或事件)”可以被解释为意思是“如果确定…”或“响应于确定…”或“在检测到(所陈述的条件或事件)时”或“响应于检测到(所陈述的条件或事件)”。
