Description

悬浮操控时的感应区域分离方法、装置、悬浮操控遥控器
本申请要求于2021年05月28日提交中国专利局、申请号为202110593296.2、申请名称为“悬浮操控时的感应区域分离方法、装置、悬浮操控遥控器”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及悬浮触控领域，尤其涉及一种悬浮操控时的感应区域分离方法、装置、悬浮操控遥控器及存储介质。
背景技术
随着悬浮触控技术的发展，通过手持操控板外设进行多指操作控制大屏成为可能，只需要通过触摸或者悬浮操控一块大小与手机相近的操控板，就能实现控制整个大屏操作，悬浮光标和触摸光标的不同，能做到手眼分离，人只需要看大屏就可以做到准确操控；多指操作，使复杂的游戏和轨迹类的应用操作在大屏上可实现，不仅大幅提升了可操控性和视觉体验，且能将手机的操作习惯无缝移植到大屏端。
在悬浮触控操作过程中，遥控器需要检测手指数和手指信息上报到大屏。遥控器从操控板获取信号变化情况来检测手指信息，包括手指数、位置、手指的触摸和悬浮状态等。指尖距离操控板高度不同在操控板上引起的感应区域大小不同，在单手指情况下或者双指在水平面相距较远的情况下，手指感应区域是能明显分开的，容易检测追踪，易区分；但是，当双指在水平面上非常靠近，尤其是在垂直面上一个手指距离悬浮操控板较远，另一个手指距离悬浮操控板较近时，较近的手指在悬浮操控板上产生的感应区域较强，较远的手指产生的感应区域较弱，此时两个手指的感应区域会合并或弱感应区域被掩盖，通过感应区域识别手指数和手指信息结果已不可靠，距离悬浮操控板较远的手指将无法被识别，手指信息丢失，用户操作无法得到正确反馈，从而极大地影响操控准确度和用户体验感。

具体实施方式
本申请提供的方法可适用于悬浮触控领域中的感应区域分离领域，本申请中的计算机设备可以为具有感应区域分离功能的实体终端，该实体终端可以为服务器，也可以为用户终端，在此不做限定。其中，服务器可以是独立的物理服务器，也可以是多个物理服务器构成的服务器集群或者分布式系统，还可以是提供云服务、云数据库、云计算、云函数、云存储、网络服务、云通信、中间件服务、域名服务、安全服务、内容分发网络(content delivery network，CDN)、以及大数据和人工智能平台等基础云计算服务的云服务器。用户终端可以包括但不限于平板设备、台式电脑、笔记本电脑、手机或者其他任何能够完成信息交互的终端设备。
在本申请提供的悬浮操控时的感应区域分离方法中，计算机设备可获取第一时间段内用户在悬浮操控板上方悬浮操作所产生的悬浮感应区域数据，悬浮感应数据包括第一时间段内的多个采样时刻以及在每个采样时刻悬浮操控板上的感应数据，多个采样时刻包括第一时刻和参考时刻，在第一时刻悬浮操控板上的感应数据只包括第一感应区域(如双指挨在一起或者重叠时的感应区域)，在参考时刻感应数据包括第二感应区域和第三感应区域，并且，参考时刻为感应数据包括两个感应区域所对应的至少一个时刻中最靠近第一时刻的时刻。之后，计算机设备确定第二感应区域的第一感应中心点和第三感应区域的第二感应中心点，并基于第一感应中心点和第二感应中心点确定第一感应区域的区域分割线。进一步地，计算机设备可基于区域分割线，对第一感应区域进行分割得到第一感应操控区域和第二感应操控区域。在本申请中，可对两个物体(如手指，感应笔等)挨在一起或者重叠时产生的一个感应区域进行分割，有效避免由于两个物体挨在一起或者重叠时，两个物体的响应区域会合并或弱响应区域被掩盖的情况，提高了操控准确度和用户体验感，适用性强。本申请提供的感应区域分离方法可适配于不同的感应区域分离应用场景，例如，悬浮操控游戏、悬浮操控绘画等诸多涉及悬浮操控的场景中具有广泛的应用场景，下面将以悬浮操控绘画应用场景为例进行说明，以下不再赘述。
在悬浮操控绘画应用场景下，本申请中的计算机设备可以为悬浮操控遥控器。请参见图1，图1是本申请提供的感应区域分离方法的应用场景示意图。如图1所示，计算机设备可以与显示屏建立通讯，在用户进行悬浮操控绘画时，用户右手中的拇指和食指在悬浮操控板区域的上方进行悬浮操作(如转动)。此时，悬浮操控遥控器获取用户右手悬浮操作过程中产生的初始悬浮操控板感应数据，该初始悬浮板感应数据包括第一时间段(即用户右手在悬浮操控板区域上方时的时间段)内的多个采样时刻以及在每个采样时刻悬浮操控板的感应数值表，并基于第一时间段内每个采样时刻悬浮操控板的感应数值表确定每个采样时刻悬浮操控板上的感应数据(即感应区域)。其中，多个采样时刻包括第一时刻和参考时刻，在第一时刻悬浮操控板上的感应数据只包括第一感应区域，在参考时刻感应数据包括第二感应区域和第三感应区域，并且，参考时刻为感应数据包括两个感应区域所对应的至少一个采样时刻中最靠近第一时刻的采样时刻。之后，计算机设备确定第二感应区域的第一感应中心点和第三感应区域的第二感应中心点，并基于第一感应中心点和第二感应中心点确定第一感应区域的区域分割线，进而，基于区域分割线，对第一感应区域进行分割得到第一感应操控区域和第二感应操控区域。在整个过程中，计算机设备可自动对双指挨在一起或者重叠时产生的感应区域进行分割，有效避免双指靠近时产生的感应区域难以分割的问题，提高了操控准确度和用户体验感，适用性强。
下面将结合图2至图7对本申请提供的悬浮操控时的感应区域分离方法进行示例说明。请参见图2，图2是本申请提供的感应区域分离方法的一流程示意图。如图2所示，该方法可包括以下步骤S101至步骤S104：
步骤S101，获取第一时间段内用户在悬浮操控板上方悬浮操作所产生的悬浮感应区域数据。
在一些可行的实施方式中，计算机设备在执行步骤S101之前，获取第一时间段内用户在悬浮操控板上方悬浮操作所产生的初始悬浮操控板感应数据。其中，初始悬浮操控板感应数据包括第一时间段内的多个采样时刻以及在每个采样时刻悬浮操控板的感应数值表，感应数值表包括悬浮操控板上每个点的感应值以及每个点的坐标值。需要说明的是，每个点的感应值大小可以反映用户在悬浮操控板上方悬浮操控过程中，确定手指、感应笔等可使悬浮操控板上的感应值发生变化的物品距离悬浮操控板的远近，示例性的，悬浮操控板上点A的感应值越大，说明手指距离点A越近。
这里，第一时间段可以为用户在悬浮操控板上方悬浮操作所对应的时间段，用户在悬浮操控板上方的悬浮操作可以为用户双指从分离状态到双指挨在一起再到双指在垂直悬浮操控板方向上重叠对应的连续操作，或者为用户操控两个感应笔从在垂直悬浮操控板方向上重叠到两个感应笔挨在一起再到两个感应笔处于分离状态对应的连续操作。其中，感应笔可以为任何在与悬浮操控板上方时悬浮操控板上的点的感应值发生变化的物体。
之后，计算机设备遍历每个采样时刻悬浮操控板的感应数值表中的每个点，将感应值大于预设感应阈值的点确定为目标点，并基于目标点构成每个采样时刻的初始感应区域，进而可采用空洞补全方法(如形态学闭操作，即先膨胀后腐蚀)对每个采样时刻的初始感应区域存在的空洞进行补全，得到每个采样时刻悬浮操控板上的感应数据，即感应区域。
可以理解的，计算机设备在获取到每个采样时刻的感应数值表后，首先利用区域搜索方法(如上述区域联通搜索法)确定由于用户悬浮操作产生的初始感应区域，之后对每个采样时刻的初始感应区域进行空洞补全，得到较为完整的可用区域，即感应区域，可提高后续的感应区域分离的成功率。
示例性的，以用户在悬浮操控板上方的悬浮操作为用户双指从分离状态到挨在一起为例，对得到第一时刻悬浮操控板上的感应区域进行介绍。请参见图3，图3是本申请提供的确定第一时刻悬浮操控板上的感应区域的工作流程示意图。如图3所示，图中包括第一组双指靠近过程中确定第一时刻悬浮操控板上的感应区域的过程，以及第二组双指靠近过程中确定第一时刻悬浮操控板上的感应区域的过程。其中，图3中的(a)至(d)内的矩形框表示悬浮操控板。下面以第一组为例进行说明，图3中的(a)表示双指靠近的过程，图3中的(b)表示双指挨在一起，图3中的(c)表示对第一时刻(即图3中的(b)对应的采样时刻)悬浮操控板的感应数值表进行区域搜索(即确定目标点的过程)后得到的第一时刻的初始感应区域(即双指可能存在的区域图，图3中的(c))，图3中的(d)为对图3中的(c)内的空洞区域进行补全后得到的第一时刻在悬浮操控板上的感应区域。图3中的第二组可以参考第一组，此处不再赘述。
进而，计算机设备得到第一时间段内用户在悬浮操控板上方悬浮操作所产生的悬浮感应区域数据。
其中，悬浮感应数据包括第一时间段内的多个采样时刻以及在每个采样时刻悬浮操 控板上的感应数据(即感应区域)，多个采样时刻包括第一时刻和参考时刻，在第一时刻悬浮操控板上的感应数据只包括第一感应区域，在参考时刻感应数据包括第二感应区域和第三感应区域，并且，参考时刻为感应数据包括两个感应区域所对应的至少一个采样时刻中最靠近第一时刻的采样时刻。
步骤S102，确定第二感应区域的第一感应中心点和第三感应区域的第二感应中心点。
在一些可行的实施方式中，计算机设备可将第二感应区域中感应值最大的点确定为第二感应区域的第一感应中心点，将第三感应区域中感应值最大的点确定为第三感应区域的第二感应中心点。其中，感应值可以为电容值。
示例性的，为了方便理解，请参见图4，图4是本申请提供的对第一感应区域进行分割的工作流程示意图。如图4所示，图4中的(a)为参考时刻悬浮操控板的感应区域，该感应区域包括第二感应区域和第三感应区域，计算机设备通过步骤S102中确定感应中心点的方式，得到第二感应区域的第一感应中心点p和第三感应区域的第二感应中心点q；图4中的(b)为第一时刻悬浮操控板的感应区域，该感应区域只包括第一感应区域，计算机设备在得到第二感应区域的第一感应中心点p和第三感应区域的第二感应中心点q后，将p和q作为第一感应区域进行分割的两个物体的参考感应中心点。
步骤S103，基于第一感应中心点和第二感应中心点确定第一感应区域的区域分割线。
在一些可行的实施方式中，计算机设备基于第一感应中心点和第二感应中心点的连接线，确定第一感应区域中垂直于连接线的目标区域，并按照连接线所在方向以及预设间隔值，将目标区域划分为与连接线所在方向一致的多个行区域，将各行区域中感应值最小的点确定为第一感应区域的区域分割点，进而根据区域分割点得到区域分割线，即图4中的(c)内的虚线mn。
示例性的，为了方便理解，请参见图5，图5是本申请提供的确定区域分割线的工作流程示意图。如图5所示，图5中的(1)为图4中的(c)对应的第一时刻悬浮操控板上详细的感应区域，即由8*16个小正方形构成的矩形区域，其中，每个小正方形表示悬浮操控板区域中的点，所有带颜色的小正方形组成的区域表示第一时刻产生的第一感应区域。假设第一感应中心点p为图5中的(1)中第4行与第7列的交点，第二感应中心点q为图5中的(1)中第4行第11列的交点，则p与q所在连线方向与矩形区域中的每行所在方向一致，分别从p和q做垂直与p与q所在连线方向的第一垂线和第二垂线，将第一垂线、第二垂线与第一感应区域所围成的区域确定为目标区域，即图5中的(2)内所有带颜色的小正方形组成的区域。之后，计算机设备按照p与q所在连线方向(即矩形区域中的每行所在方向)以及预设间隔值(即每个点对应的小正方形的宽度值)，将目标区域划分为6个行区域，即第2行中第7列至第11列构成的第一行区域，第3行中第7列至第11列构成的第二行区域，…，第7行中第7列至第11列构成的第六行区域。进而，计算机设备将第一行区域中感应值最小的点确定为第一区域分割点，将第二行区域中感应值最小的点确定为第二区域分割点，…，将第六行区域中感应值最小的点确定为第六区域分割点，并将上述六个区域分割点进行连接，得到图5中的(3)内的虚线mn，也即图5中的(4)所示第一感应区域的区域分割线mn。
步骤S104，基于区域分割线，对第一感应区域进行分割得到第一感应操控区域和第二感应操控区域。
示例性的，请再参见图4，图4中的(d)内区域分割线以左的第一感应区域为第一感应操控区域，区域分割线以右的第一感应区域为第二感应操控区域。
需要说明的是，在第一时刻悬浮操控板上的感应区域是由于用户双指挨在一起产生的感应区域时，假设第二感应区域和第三感应区域分别为第一手指产生的感应区域和第二手指产生的感应区域，则在将第一感应区域分割为两个区域后，将两个区域中包括第一感应中心点的区域确定为第一感应操控区域(即第一手指感应操控区域)，进而将两个区域中的另一个区域确定为第二感应操控区域(即第二手指感应操控区域)。
在本申请实施例中，计算机设备可基于参考时刻(即与第一时刻最靠近的两个物体可分离的采样时刻)产生的两个感应区域的感应中心点作为第一时刻产生的第一感应区域的两个参考分割中心点，并基于两个参考分割中心点确定第一感应区域的区域分割线，进而基于该区域分割线，对第一感应区域进行分割得到第一感应操控区域和第二感应操控区域，可对两个物体(如手指，感应笔等)挨在一起或者重叠时产生的一个感应区域进行分割，有效避免由于两个物体挨在一起或者重叠时，两个物体的响应区域会合并或弱响应区域被掩盖的情况，提高了操控准确度和用户体验感，适用性强。
请参见图6，图6是本申请提供的感应区域分离方法的另一流程示意图。如图6所示，该方法可包括以下步骤S201至步骤S206：
步骤S201，获取第一时间段内用户在悬浮操控板上方悬浮操作所产生的悬浮感应区域数据。
步骤S202，确定第二感应区域的第一感应中心点和第三感应区域的第二感应中心点。
步骤S203，基于第一感应中心点和第二感应中心点确定第一感应区域的区域分割线。
步骤S204，基于区域分割线，对第一感应区域进行分割得到第一感应操控区域和第二感应操控区域。
这里，步骤S201-步骤S204具体实现方式的描述请参见图2所示实施例中的步骤S101-步骤S104，此处不再赘述。
步骤S205，确定第一感应操控区域的第一区域感应特征值和第二感应操控区域的第二区域感应特征值。
在一些可行的实施方式中，计算机设备将第一感应操控区域中所有点的感应值的均值确定为第一区域感应特征值，将第二感应操控区域中所有点的感应值的均值确定为第二区域感应特征值。
步骤S206，在第一区域感应特征值与第二区域感应特征值之间的差值大于预设差值阈值的情况下，基于第一起始点、第二起始点和在第一时刻悬浮操控板的感应数值表，确定第一目标感应操控区域和第二目标感应操控区域。
其中，第一时刻悬浮操控板的感应数值表中包括悬浮操控区域内每个点的坐标值以及感应值。
在一些可行的实施方式中，计算机设备计算第一区域感应特征值与第二感应特征值之间的差值，在该差值大于预设差值阈值时，确定步骤S204得到的第一感应操控区域与第二感应操控区域存在信息丢失的情况，说明得到的第一感应操控区域与第二感应操控区域分割不准确。之后，计算机设备基于第一起始点和在第一时刻悬浮操控板的感应数值表确定第一目标感应操控区域，基于第二起始点和在第一时刻悬浮操控板的感应数值表确定第二目标感应操控区域。其中，第一起始点为第一感应操控区域中感应值最大的点，第二起始点为第二感应操控区域中感应值最大的点。
之后，计算机设备以第一起始点为中心，按8邻域向四周搜索满足第一条件的点，这些 点构成第一目标感应操控区域；同时，以第二起始点为中心，按8邻域向四周搜索满足第二条件的点，这些点构成第二目标感应操控区域。其中，第一条件为以第一起始点为中心向外的点的感应值呈下降趋势，第二条件为以第二起始点为中心向外的点的感应值呈下降趋势。
具体的，计算机设备将与第一起始点相邻的八个点(即与第一起始点的上下左右相邻的四个点以及与第一起始点对角相邻的四个点)中，感应值小于第一起始点的感应值的点确定为第一目标点，并将第一起始点和第一目标点添加至第一目标点集合。之后，计算机设备判断与第一目标点相邻的多个点中是否存在感应值小于第一目标点的感应值的点，若存在，则将感应值小于第一目标点的感应值的点确定为第一目标点，并将第一目标点添加至第一目标点集合，可以理解，通过上述循环可以得到第一时刻悬浮操控板上所有满足第一条件的点，也即第一目标点集合包括第一起始点和第一时刻悬浮操控板上所有满足第一条件的点。进而，计算机设备根据第一目标点集合中每个点的坐标值组成第一目标感应操控区域。
与此同时，计算机设备将与第二起始点相邻的八个点(即与第二起始点的上下左右相邻的四个点以及与第二起始点对角相邻的四个点)中，感应值小于第二起始点的感应值的点确定为第二目标点，并将第二起始点和第二目标点添加至第二目标点集合。之后，计算机设备判断与第二目标点相邻的多个点中是否存在感应值小于第二目标点的感应值的点，若存在，则将感应值小于第二目标点的感应值的点确定为第二目标点，并将第二目标点添加至第二目标点集合，可以理解，通过上述循环可以得到第一时刻悬浮操控板上所有满足第二条件的点，也即第二目标点集合包括第二起始点和第一时刻悬浮操控板上所有满足第二条件的点。进而，计算机设备根据第二目标点集合中每个点的坐标值组成第二目标感应操控区域。
可以理解的，上述确定第一目标感应操控区域和第二目标感应操控区域的过程为采用梯度下降的区域搜索方法对悬浮操控板区域进行二次区域搜索，从而对第一感应操控区域和第二感应操控区域进行补充，得到补充完整的第一目标感应操控区域和第二目标感应操控区域，可进一步提高感应区域的分割正确率。需要说明的是，这里进行二次区域搜索的方法包括但不限于梯度下降法，其他的区域搜索法同样适用于本申请。
进一步地，在得到第一目标感应操控区域和第二目标感应操控区域后，计算机设备可对第一目标感应操控区域和第二目标感应操控区域进行重新规划，使最终得到的两个感应区域更加符合两个物体(如手指)的当前位置。
示例性的，为了方便理解，请参见图7，图7是本申请提供的第一目标感应操控区域和第二目标感应操控区域的效果示意图。如图7所示，图7中的(a)为步骤S204得到的第一感应操控区域和第二感应操控区域，以及步骤S205得到的第一感应操控区域的第一区域感应特征值s和第二感应操控区域的第二区域感应特征值r；图7中的(b)为计算机设备分别以s和r为起始点分别向四周重新进行区域搜索和规划后得到的第一目标感应操控区域和第二目标感应操控区域，其中，上述两个区域中的相交区域(即阴影区域)为两个物体产生的感应区域中的重叠部分。
在本申请实施例中，计算机设备可基于参考时刻(即与第一时刻最靠近的两个物体可分离的采样时刻)产生的两个感应区域的感应中心点作为第一时刻产生的第一感应区域的参考分割中心点，并基于该参考分割中心点确定第一感应区域的区域分割线，进而基于该区域分割线，对第一感应区域进行分割得到第一感应操控区域和第二感应操控区域。之后，可通过第一感应操控区域的第一区域感应特征值与第二感应操控区域的第二区域感应特征值之间的差值确定分割是否正确，并在分割不正确的情况下，分别以第一感应操控区域中感应值最大的点和第二感应操控区域中感应值最大的点为起始点分别向四周重新进行区域搜索和规划， 得到第一目标感应操控区域和第二目标感应操控区域，可进一步提高感应区域的分割正确率，有效避免由于两个物体挨在一起或者重叠时，两个物体的响应区域会合并或弱响应区域被掩盖的情况，进一步提高了操控准确度和用户体验感，适用性更强。
