Description

图像旋转的控制、显示方法、装置、介质及系统
本申请要求于2018年12月11日提交中国专利局、申请号为201811508632.3、发明名称为“图像旋转的控制方法及装置、图像旋转的显示方法及系统”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
本申请属于数据处理技术领域,尤其涉及一种图像旋转的控制、显示方法、装置、介质及系统。
背景技术
随着数据处理技术的发展,设备和设备之间的数据交互日益密切,其中一种常见的数据交互形式体现为将一个设备上的操作同步地在其他设备上执行,使得多台设备出现相同的用户界面,从而为不同的用户呈现相同的执行结果。但是在实际操作中,由于不同的设备的操作系统、屏幕分别率以及应用软件版本等参数均可能存在差异,所以在多个设备同步操作时,经常会遇到不同的设备在根据同一个设备进行同步操作时显示出的用户界面不同,甚至出现用户界面显示异常的现象,即用户界面不兼容的情况发生。
目前,往往需要人工通过观察各自的设备是否存在用户界面的显示异常,才能判断用户界面的兼容性是否出现异常,这样的判断方法效率非常低,而且由于一台设备的使用者可能不清楚其他设备上用户界面的显示情况,所以可能存在设备兼容性的判断不准确的问题。
技术问题
现有技术在识别异常的业务请求时存在实时性较差的问题。

本发明的实施方式
为了说明本申请所述的技术方案,下面通过具体实施例来进行说明。
图1示出了本申请实施例提供的图像旋转的控制方法的实现流程,该方法流程包括步骤S101至S106。各步骤的具体实现原理如下。
S101,在将三维图像发送至显示设备后,检测用户输入的滑动轨迹以及滑动速度,并分别计算所述滑动轨迹以及所述滑动速度沿坐标系X轴和Y轴的分量,生成X轴轨迹分量、Y轴轨迹分量、X轴速度分量以及Y轴速度分量,所述坐标系还包括Z轴。
本申请实施例涉及两类设备,一类为控制设备,另一类为显示设备,其中,控制设备是用于生成和获取三维图像,并接收用户的操作、生成对所述三维图像的控制指令的设备,显示设备是用于在接收从控制设备发送的三维图像后,根据控制设备发送的控制指令,显示该三维图像的旋转情况的。
值得注意地,与本申请实施例对应的权利要求的执行主体是控制设备,所以本申请实施例的介绍主要以控制设备一侧为主。
在本申请实施例中,控制设备可以通过触摸屏接收用户的操作。具体地,控制设备通过触摸屏接收用户的滑动轨迹以及滑动速度,其中,滑动轨迹可以为用户在触摸屏上真实的滑动路线,也可以是该真实的滑动路线的近似拟合的直线。可以理解地,由于触摸屏是一个平面,所以用户的滑动轨迹自然可以被分解为沿坐标系X轴和Y轴的分量,生成X轴轨迹分量、Y轴轨迹分量。基于同样的理由,滑动速度也可以被分解为沿坐标系X轴的速度以及沿坐标系Y轴的速度,生成X轴速度分量以及Y轴速度分量。
值得注意地,由于三维图像可以沿三个维度进行旋转,所以为了控制三维图像全方位的旋转,本申请实施例的坐标系是一个三维坐标系,因此坐标系还包括Z轴,以使本申请实施例在后续的步骤中可以分别生成三维的控制指令。
S102,判断所述Y轴轨迹分量与所述X轴轨迹分量的比值是否符合预设条件,并且判断所述X轴速度分量以及所述Y轴速度分量中较大的数值是否小于预设的速度阈值。
可以理解地,如上文所述,控制设备只能将用户输入的滑动轨迹和滑动速度分为沿X轴的分量以及沿Y轴的分量,即控制设备只能直接得到滑动轨迹和滑动速度的二维分量,而如果想控制三维图像全方位的旋转,还必须在某些条件达成的情况下,根据滑动轨迹和滑动速度的二维分量生成对应的第三维分量,即沿Z轴的分量,从而生成Z轴指令以控制三维图像在显示设备中沿Z轴旋转。
因此,判断滑动轨迹和滑动速度的二维分量是否达成某些条件是是否生成滑动轨迹和滑动速度沿Z轴的分量的必不可少的步骤。
一方面,本申请实施例需要判断滑动轨迹的二维分量是否达成某些条件。可以理解地,如果滑动轨迹沿Y轴的分量与沿X轴的分量相差很多,自然可以将滑动轨迹理解为用户的滑动轨迹大体是沿Y轴方向或沿X轴方向滑动的,也就是客户的滑动轨迹所表征的意图是清晰的,反之,如果滑动轨迹沿Y轴的分量与沿X轴的分量相差不大,则用户的滑动轨迹所表征的意图是模糊的,因此可想而知,如果按照这样的滑动轨迹对三维图像进行控制,则可能三维图像的旋转方式与用户的真实意图不符,所以这种情况发生时,不应该生成相关的控制指令,以避免误操作。
可选地,所述预设条件可以为:Y轴轨迹分量与所述X轴轨迹分量的比值小于预设的第一比值阈值,或所述Y轴轨迹分量与所述X轴轨迹分量的比值大于预设的第二比值阈值,所述第一比值阈值小于第二比值阈值。可选地,第一预设的比值阈值为0.25,第二预设的比值阈值为4。
另一方面,本申请实施例需要判断滑动轨迹的二维分量是否达成某些条件。值得注意地,本申请实施例需要判断X轴速度分量或Y轴速度分量中较大的数值不小于预设的速度阈值,以确定是否根据滑动轨迹和滑动速度的二维分量生成对应的第三维分量。
S103,若所述Y轴轨迹分量与所述X轴轨迹分量的比值不符合预设条件,则不生成控制指令。
在这种情况下,如上文所述,证明用户的滑动轨迹所表征的意图不清晰,为了避免误操作,所以本申请实施例不生成控制指令。
S104,若所述Y轴轨迹分量与所述X轴轨迹分量的比值符合预设条件,且所述X轴速度分量以及所述Y轴速度分量中较大的数值均小于预设的速度阈值,则生成控制所述三维图像沿所述X轴旋转的X轴指令或沿所述Y轴旋转的Y轴指令。
在这种情况下,如上文所述,证明用户的滑动轨迹所表征的意图是清晰的,而且沿X轴和Y轴的速度分量均不大,所以不会生成控制三维图像沿Z轴旋转的Z轴分量。
可选地,在所述Y轴轨迹分量与所述X轴轨迹分量的比值符合预设条件的前提下,若所述Y轴轨迹分量与所述X轴轨迹分量的比值小于预设的第一比值阈值,且所述X轴速度分量小于预设的所述速度阈值,则生成控制所述三维图像沿所述X轴旋转的X轴指令。
具体地,可以根据预设的轨迹分量与旋转角度的对应关系,计算所述X轴速度分量对应的旋转角度作为被选角度,生成的X轴指令为:控制三维图像沿X轴顺时针旋转被选角度的指令。
可选地,在所述Y轴轨迹分量与所述X轴轨迹分量的比值符合预设条件的前提下,若所述Y轴轨迹分量与所述X轴轨迹分量的比值大于预设的第二比值阈值,且所述Y轴速度分量小于预设的所述速度阈值,则生成控制所述三维图像沿所述Y轴旋转的Y轴指令。
具体地,可以根据预设的轨迹分量与旋转角度的对应关系,计算所述Y轴速度分量对应的旋转角度作为被选角度,生成的Y轴指令为:控制三维图像沿Y轴顺时针旋转被选角度的指令。
S105,若所述Y轴轨迹分量与所述X轴轨迹分量的比值符合预设条件,且所述X轴速度分量以及所述Y轴速度分量中较大的数值不小于预设的速度阈值,则生成控制所述三维图像沿所述Z轴旋转的Z轴指令。
在这种情况下,如上文所述,证明用户的滑动轨迹所表征的意图是清晰的,而且X轴速度分量以及所述Y轴速度分量中至少有一个数值达到了预设的速度阈值,因此就会根据滑动轨迹沿X轴速度分量以及所述Y轴速度分量中较大的数值对应的坐标轴的轨迹分量,计算Z轴指令,以控制所述三维图像沿所述Z轴旋转的Z轴指令。
具体地,可以根据预设的轨迹分量与旋转角度的对应关系,计算滑动轨迹沿X轴速度分量以及所述Y轴速度分量中较大的数值对应的坐标轴的轨迹分量对应的旋转角度作为被选角度,生成的Z轴指令为:控制三维图像沿Z轴顺时针旋转被选角度的指令。
值得注意地,生成的Z轴指令不限于上述方式,本申请的其他实施例还通过其他方式生成Z轴指令。
可以理解地,本申请实施例根据上述计算流程,通过对二维数据的计算实现了生成第三维控制指令的目的。
S106,将所述Z轴指令发送至所述显示设备,以控制显示设备中的所述三维图像沿所述Z轴旋转。
可以理解地,本申请实施例通过在将三维图像发送至显示设备后,检测用户输入的滑动轨迹以及滑动速度,并分别计算滑动轨迹以及滑动速度沿坐标系X轴和Y轴的分量,若轴轨迹分量与X轴轨迹分量的比值符合预设条件,且X轴速度分量以及所述Y轴速度分量中较大的数值不小于预设的速度阈值,则生成控制所述三维图像沿所述Z轴旋转的Z轴指令,以根据二维的滑动轨迹生成关于第三维的旋转指令,将所述Z轴指令发送至显示设备,以控制显示设备中的三维图像沿所述Z轴旋转,从而使用户更便捷的控制异地显示的三维图像进行全方位的旋转。
作为本申请的一个实施例,如图2所示,上述S105包括:
S1051,调取历史操作记录,所述历史操作记录包含多个历史X轴速度分量与时间差值的对应关系,以及历史Y轴速度分量与时间差值的对应关系,所述时间差值为录入所述历史X轴速度分量或所述历史Y轴速度分量的时间到当前时间的差值。
在本申请实施例中,考虑到操作一个控制设备(如一台触屏手机)的往往是一个用户,而不同的用户的操作习惯都有不同。如果简单的根据预设的轨迹分量与旋转角度的对应关系确定旋转角度,可能存在显示设备中三维图像的旋转情况不符合用户的操作期望,因此简单的根据预设的轨迹分量与旋转角度的对应关系确定旋转角度可能存在用户体验差的问题。
基于上述原因,本申请实施例调取控制设备的历史操作记录,并在后续的步骤基于这个历史操作记录,在需要生成Z轴指令时,生成符合用户操作习惯的Z轴指令。
S1052,若所述X轴速度分量不小于所述Y轴轨迹分量,则将所述历史X轴速度分量作 为历史被选分量,若所述X轴速度分量小于所述Y轴轨迹分量,则将所述历史Y轴速度分量作为历史被选分量。
S1053,通过加权公式计算历史被选分量的加权平均值。
可选地,所述加权公式包括:
Figure PCTCN2019091532-appb-000001
所述Index为所述历史被选分量的加权平均值,所述Speed i为所述历史操作记录中第i个历史被选分量,所述Time i为所述历史操作记录中第i个历史被选分量对应的时间差值,所述e为自然常数,所述n为所述预设数量。
可以理解地,在本申请实施例中,一个历史被选分量对应的时间差值越大,证明该历史被选分量生成的时间越久,则通过
Figure PCTCN2019091532-appb-000002
计算出的该历史被选分量对应的权重就越小,从而使得该历史被选分量对加权平均值的影响越小。
S1054,将所述X轴速度分量以及所述Y轴速度分量中较大的数值作为目标分量,根据所述历史被选分量的加权平均值以及所述目标分量,计算所述三维图像沿所述Z轴应旋转的角度,并将所述应旋转的角度作为Z轴指令。
可选地,计算所述历史被选分量的加权平均值除以目标分量的商作为第一目标参数;计算所述第一目标参数与所述目标分量的乘积,作为第二目标参数;根据预设的参数与旋转角度的对应关系,确定所述第二目标参数对应的旋转角度作为所述三维图像沿所述Z轴应旋转的角度。
可以理解地,通过上述计算过程,使得在确定Z轴指令时,考虑了控制设备的用户的操作习惯,因此相同的滑动速度和滑动轨迹,可能在不同的控制设备中对应不同的三维图像沿所述Z轴应旋转的角度,提高Z轴指令生成的差异性,提高用户感受。
作为本申请的一个实施例,如图3所示,示出了一种图像旋转的显示方法的流程图,在本申请实施例中,图像旋转的显示方法涉及控制终端和显示终端的交互过程,其中,由于在上文实施例中已经对控制终端一侧做了详细的介绍,因此不在此进行赘述,在本申请实施例中,主要对显示终端一侧做介绍。
S301,控制设备将三维图像发送至显示设备,并检测用户输入的滑动轨迹以及滑动速度。
S302,显示设备获取控制设备发送的三维图像,并计算所述三维图像从预设角度进行投影时生成的平面影像的长和宽,将所述长和宽中较大的数值作为目标边长。
在本申请实施例中,通过Canvas画布技术显示三维图像。由于在现有技术中,通过长 方形画布显示三维图像往往会导致三维图像在旋转过程中,由于投影的长和宽的改变,导致三维图像的显示存在失真的问题。所以为了解决上述问题,本申请实施例采用正方形画布显示三维图像。正方形画布的边长为所述三维图像从预设角度进行投影时生成的平面影像的长和宽中较大的数值。
S303,所述显示设备生成正方形画布,并通过所述正方形画布显示所述三维图像的初始图像,所述正方形画布的边长为所述目标边长,所述初始图像为从所述预设角度观看所述三维图像时的图像。
在实际运用中,通过正方形画布显示的三维图像在旋转过程中不会出现失真问题。
S304,所述控制设备分别计算所述滑动轨迹以及所述滑动速度沿坐标系X轴和Y轴的分量,生成X轴轨迹分量、Y轴轨迹分量、X轴速度分量以及Y轴速度分量,所述坐标系还包括Z轴。
S305,若所述Y轴轨迹分量与所述X轴轨迹分量的比值符合预设条件,且所述X轴速度分量以及所述Y轴速度分量中较大的数值不小于预设的速度阈值,则所述控制设备生成控制所述三维图像沿所述Z轴旋转的Z轴指令。
S306,所述控制控制将所述Z轴指令发送至所述显示设备。
S307,所述显示设备在接收到控制设备发送的旋转指令后,显示根据所述旋转指令进行旋转后的三维图像。
可以理解地,显示设备在上述的正方形画布中显示旋转后的三维图像。
本申请实施例中的显示设备通过正方形画布显示三维图像,避免了三维图像在旋转过程中存在的失真的问题。
