Description

仿真灭火器松动干粉的方法、装置、设备及存储介质 技术领域
本发明涉及运动捕捉领域，尤其涉及一种仿真灭火器松动干粉的方法、装置、设备及存储介质。
背景技术
干粉灭火器在使用之前，需要让干粉灭火器里面的干粉充分松动，才可以将干粉灭火器用于灭火处理，而采用虚拟场景模拟干粉灭火器松动干粉的过程，使人们能加深使用干粉灭火器的印象，并能在遇到危险时正确地使用干粉灭火器。
在现有技术中，采用将灭火器依附到应用动捕系统的手柄上，手柄移动带动灭火器移动，通过计算灭火器的当前帧和上一帧的位置差，并除以从上一帧移动到当前帧所消耗的时长，得到灭火器移动的实时速度，如果速度超过阈值，则可以进行计时，如果速度低于阈值，则重置计时，得到时长，如果时长达到阈值，则说明灭火器里的干粉已成功松动，可以进入下一步操作。但是该仿真并不符合灭火器的操作的正确性，导致用户在面对真实火灾现场时灭火效率较低。

具体实施方式
本发明实施例提供了一种仿真灭火器松动干粉的方法、装置、设备及存储介质，通过两只手柄控制游戏场景中灭火器的上下颠倒操作，实时计算灭火器的Z轴方向和竖直向上之间的夹角值，并根据夹角值统计灭火器的已颠倒次数，直到灭火器内干粉已完成松动，通过模拟虚拟场景使得用户能正确使用干粉灭火器松动干粉，并提高真实火灾现场中的灭火效率。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)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。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”或“具有”及其任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
为便于理解，下面对本发明实施例的具体流程进行描述，请参阅图1，本发明实施例中仿真灭火器松动干粉的方法的一个实施例包括：
101、初始化灭火器的Z轴方向为竖直向上的方向，并获取竖直方向的单位向量。
其中，单位向量是指模等于1的向量，单位向量是非零向量，并且具有确定的方向，因此，服务器从竖直方向中采集对应的模为1的向量，得到竖直方向的单位向量。
需要说明的是，在虚拟场景中，初始化灭火器的Z轴方向为竖直向上的 方向，也就是灭火器的Z轴方向的初始状态与竖直方向保持一致。当一个物体只处于“上-下”方向排成直线时，被称为竖直方向，也就是与地平线或水平线垂直，进一步地，服务器将地面的大地坐标系的z轴作为竖直方向，灭火器为干粉灭火器。
可以理解的是，本发明的执行主体可以为仿真灭火器松动干粉的装置，还可以是终端或者服务器，具体此处不做限定。本发明实施例以服务器为执行主体为例进行说明。
102、当接收到动捕数据时，实时获取灭火器的Z轴方向的单位向量，动捕数据用于指示对灭火器进行上下颠倒操作。
其中，动捕数据为运动捕捉系统实时采集的数据，运动捕捉的实质就是要测量、跟踪和记录物体在三维空间中的运动轨迹。灭火器在上下颠倒操作中，灭火器的Z轴方向也会随着灭火器的运动方向实时变化，因此服务器实时从灭火器的Z轴方向中采集模为1的向量，得到灭火器的Z轴方向的单位向量。
需要说明的是，对灭火器执行上下颠倒操作，采用两只手将灭火器上下翻转，也就是，用户左右手各拿一只动作捕捉的手柄，两个手柄上都预先绑上动捕数据的刚体，即手柄在真实场景中的位置可应用到虚幻4的世界中，将灭火器的把手依附到一只手柄上，另一只手柄触碰到灭火器的底部，当任意一只手柄在实际场景中画圆到达另一只手柄处，将带动虚拟场景中灭火器进行上下颠倒操作，直到灭火器中干粉已完全松动，就可进入下一步对灭火器的使用操作。
103、对灭火器的Z轴方向的单位向量和竖直方向的单位向量进行夹角计算，得到夹角值。
具体的，服务器对灭火器的Z轴方向的单位向量进行取模运算，得到第一模值；服务器对竖直方向的单位向量进行取模运算，得到第二模值；服务器根据第一模值与第二模值进行乘法运算，得到第一运算结果；服务器对灭火器的Z轴方向的单位向量和竖直方向的单位向量进行乘积运算，得到第二运算结果，第二运算结果为1；服务器对灭火器的Z轴方向的单位向量和竖直方向的单位向量进行乘法运算，得到初始向量积；服务器将初始向量积除以第二运算结果，得到目标向量积，服务器根据反余弦函数对目标向量积进行 计算，得到夹角值。
104、根据夹角值、最小阈值和最大阈值更新已颠倒次数和累加标识，累加标识用于指示是否对已颠倒次数进行次数更新。
在灭火器在上下颠倒操作过程中，当夹角值小于最小阈值时，服务器设置累加次数为第一目标值，累加标识用于指示是否对已颠倒次数进行次数更新；当夹角值大于或者等于最小阈值，并且夹角值小于最大阈值时，服务器继续执行颠倒操作；当夹角值大于或者等于最大阈值，并且累加标识为第一目标值时，对已颠倒次数进行加1操作，已颠倒次数为大于或者等于0的整数，同时将累加标识设置为第二目标值。例如，最小阈值为5度，最大阈值为176度，夹角值的取值区间大于或者等于0度，并且小于或者等于180度。
需要说明的是，第一目标值用于指示逻辑真，第二目标值用于指示逻辑假。当灭火器的Z轴方向从竖直向上的方向旋转移动到从竖直向下的方向时，对已颠倒次数累加一次，当灭火器的Z轴方向从竖直向下的方向向竖直向下的方向旋转移动时，即使存在夹角值大于或者等于最大阈值的情况，但是由于累加标识为第二目标值，服务器也不会重复统计已颠倒次数，确保已颠倒次数的正确性。
105、当已颠倒次数大于或者等于预设的成功颠倒次数，并且夹角值小于或者等于最小阈值时，确定灭火器中的干粉已完成松动。
服务器重复执行步骤102至步骤104，直到已颠倒次数大于或者等于预设的成功颠倒次数时，服务器判断夹角值是否小于或者等于最小阈值，若夹角值大于最小阈值，则将灭火器的Z轴方向旋转移动到竖直向上的方向；若夹角值小于或者等于最小阈值，则确定灭火器中的干粉已完成松动，可以对灭火器进行其他操作。例如，当预设的成功颠倒次数为10，已颠倒次数为11，并且夹角值小于最小阈值，则服务器灭火器中的干粉已完成松动。
可以理解的是，对灭火器进行上下颠倒操作，也可以应用到教学或消防演练中，使得人们能够对灭火器进行正确的操作，采用上下颠倒方式让灭火器中的干粉充分松动，达到较好的灭火效果。
本发明实施例中，通过两只手柄控制游戏场景中灭火器的上下颠倒操作，实时计算灭火器的Z轴方向和竖直向上之间的夹角值，并根据夹角值统计灭火器的已颠倒次数，直到灭火器内干粉已完成松动，通过模拟虚拟场景使得 用户能正确使用干粉灭火器松动干粉，并提高真实火灾现场中的灭火效率。
请参阅图2，本发明实施例中仿真灭火器松动干粉的方法的另一个实施例包括：
201、初始化灭火器的Z轴方向为竖直向上的方向，并获取竖直方向的单位向量。
服务器初始化灭火器的Z轴方向为竖直向上的方向，也就是初始状态时，灭火器的Z轴方向与竖直方向的方向一致，但在灭火器上下颠倒操作过程中，灭火器的Z轴方向是实时变化的。服务器可以获取模为1的竖直方向的向量作为竖直方向的单位向量，也可以获取一个竖直方向的非零向量，并将该非零向量除以该非零向量的模，得到竖直方向的单位向量，具体此处不做限定。
202、当接收到动捕数据时，根据预置函数实时计算灭火器的Z轴方向的单位向量，动捕数据用于指示对灭火器进行上下颠倒操作。
在控制灭火器上下颠倒操作之前，首先将两个手柄绑上动捕数据的刚体，实现两个手柄与灭火器的虚拟互连，两个手柄上的动作捕捉传感器实时采集各自对应的运动过程，服务器根据两个手柄的动捕数据实现对灭火器的虚拟操作，确保游戏场景中的手柄和真实场景中的手柄位置旋转同步。进一步地，在一个手柄上采用用户界面提示用户使用该手柄触碰灭火器，并按住中指键，使灭火器依附到该手柄上，此时另一个手柄上采用用户界面提示用户使用这个手柄触碰到灭火器底部区域，并按住中指键，此时对灭火器进行上下颠倒操作，并开始颠倒灭火器的计算。
具体的，当接收到动捕数据时，服务器根据预置函数实时计算灭火器的Z轴方向的单位向量，动捕数据用于指示对灭火器进行上下颠倒操作，其中，预置函数可以为虚幻游戏中的获取向量函数GetActorUpVector()。
可以理解的是，利用运动捕捉技术捕捉用户的各种动作，驱动虚拟环境中颠倒动作，能够给用户以一种全新的参与感受，加强对灭火器正确使用方式的真实感和互动性。
203、根据预置夹角公式对灭火器Z轴方向的单位向量和竖直方向的单位向量进行计算，得到夹角值。
进一步地，设置灭火器Z轴方向的单位向量a，竖直方向的单位向量b，预置夹角公式为θ＝a cos(a·b)，将a和b代入θ＝a cos(a·b)进行计算，得到夹角值 θ。其中，夹角值为当前帧的灭火器的夹角值，由于灭火器的Z轴方向随着上下颠倒操作一直在变化，因为服务器需要实时计算当前帧的灭火器的夹角值。
需要说明的是，两个向量的夹角的余弦函数公式为
Figure PCTCN2021077224-appb-000001
那么对应的反余弦函数公式为
Figure PCTCN2021077224-appb-000002
若将向量c和d转化为对应的单位向量a和单位向量b，也就是模为1的向量，则可以确定最终的夹角值计算公式为θ＝a cos(a·b)，也就是预置夹角公式，服务器通过该预置夹角公式计算得到当前帧的灭火器Z轴方向与竖直方向的夹角值。
204、判断夹角值是否大于最小阈值。
具体的，服务器获取最小阈值；服务器将夹角值与最小阈值进行差运算，得到运算结果；服务器判断运算结果是否大于0；若夹角值大于0，则服务器确定夹角值大于最小阈值；若运算结果小于或者等于0，则服务器确定夹角值小于或者等于最小阈值。
举例说明，服务器设置最小阈值为13度，若夹角值为20度，则服务器确定夹角值大于最小阈值；若夹角值为6度或者13度，则服务器确定夹角值小于或者等于最小阈值。
205、若夹角值小于或者等于最小阈值，则设置累加标识为逻辑真，累加标识用于指示是否对已颠倒次数进行次数更新。
若夹角值小于或者等于最小阈值，则服务器确定灭火器在上下颠倒操作过程中，灭火器的Z轴方向还未从竖直向上的方向旋转移动到竖直向下的方向，或者灭火器的Z轴方向从竖直向下的方向重新向竖直向上的方向旋转移动，则服务器累加标识为逻辑真，逻辑真用于指示服务器能够对已颠倒次数进行次数更新。其中，已颠倒次数用于统计将灭火器成功上下颠倒测次数，对该已颠倒次数进行更新的限制条件就是服务器确定累加标识为逻辑真时，才可以更新已颠倒次数。
可以理解的是，累加标识为布尔型变量，布尔型变量是指具有两种逻辑状态的变量，也就是逻辑真和逻辑假。可以采用1或者0表示累加标识的逻辑真或者逻辑假，也可以采用true或者false表示累加标识的逻辑真或者逻辑假，具体此处不做限定。
206、若夹角值大于最小阈值，则根据夹角值、最大阈值和累加标识对已颠倒次数进行更新。
其中，最大阈值用于指示灭火器的Z轴方向从竖直向上的方向旋转移动到竖直向下的方向中，例如，设置最大阈值为170度。可以理解的是，服务器将上下颠倒的区域划分为夹角值小于或者等于最小阈值的第一颠倒区域、夹角值大于最小阈值并且夹角值小于最大阈值的第二颠倒区域、以及夹角值大于或者等于最大阈值的第三颠倒区域。具体的，若夹角值大于最小阈值，则服务器判断夹角值是否小于最大阈值；若夹角值小于最大阈值，则继续对灭火器进行上下颠倒操作；若夹角值大于或者等于最大阈值，则服务器根据累加标识对已颠倒次数进行更新，进一步地，若夹角值大于最小阈值，则判断夹角值是否小于最大阈值；若夹角值小于最大阈值，则继续对灭火器进行上下颠倒操作；若夹角值大于或者等于最大阈值，则根服务器据累加标识对已颠倒次数进行更新，进一步地，若所述夹角值大于或者等于所述最大阈值，则服务器判断所述累加标识是否为所述逻辑真；若所述累加标识为所述逻辑真，则服务器获取所述已颠倒次数，并对所述已颠倒次数进行加1计算，所述已颠倒次数的初始值为0，例如，已颠倒次数为3，再次对灭火器成功上下颠倒一次，则已颠倒次数为4；服务器将所述累加标识设置为逻辑假。
需要说明的是，当灭火器的Z轴方向处于第一颠倒区域时，服务器将累加标识设置为逻辑真；当灭火器的Z轴方向处于第三颠倒区域时，服务器将累加标识设置为逻辑假，此时，服务器受条件约束，不能对已颠倒次数进行次数更新，防止存在一次颠倒成功，多次更新已颠倒次数，导致统计成功对灭火器进行上下颠倒的次数不准确的问题。
207、当已颠倒次数大于或者等于预设的成功颠倒次数，并且夹角值小于或者等于最小阈值时，确定灭火器中的干粉已完成松动。
具体的，服务器判断已颠倒次数是否小于预设的成功颠倒次数；若已颠倒次数小于预设的成功颠倒次数，则服务器继续执行步骤202至206；若已颠倒次数大于或者等于预设的成功颠倒次数，则服务器判断夹角值是否大于最小阈值；若夹角值大于最小阈值，则服务器继续执行步骤202至206；若夹角值小于或者等于最小阈值，则灭火器的Z轴方向为竖直向上的方向，此时，灭火器处于正立抓举的状态，即可视为灭火器已完成上下颠倒，灭火器内干粉已完成松动，灭火器可以进入下一步使用操作。
可选的，在灭火器上下颠倒的过程中，若用户松开中指键，则服务器接 收到接收游戏结束指令，灭火器将掉落在虚拟场景中的地面上，此时将已颠倒次数重新设置为0，若游戏需重新进行上述计算。
本发明实施例中，通过两只手柄控制游戏场景中灭火器的上下颠倒操作，实时计算灭火器的Z轴方向和竖直向上之间的夹角值，并根据夹角值统计灭火器的已颠倒次数，直到灭火器内干粉已完成松动，通过模拟虚拟场景使得用户能正确使用干粉灭火器松动干粉，并提高真实火灾现场中的灭火效率。
