具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。
应当明确,所描述的实施例仅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作出创造性劳动前提下所获得的所有其它实施例,都属于本发明保护的范围。
实施例一:
图1为本实施例提供的虚拟现实系统的视角调节方法流程图,如图1所示,该方法包括:
S110,在进入虚拟现实系统的虚拟现实场景后,判断是否接收到进入视角选择模式的控制信号,在接收到进入视角选择模式的控制信号时,进入虚拟现实系统的视角选择模式。
本步骤所述的控制信号可以响应于实体按钮的触发操作,也可以响应于虚拟按键的触发操作。具体的,在虚拟现实系统的显示设备上设置视角调节按钮,检测是否发生视角调节按钮的触发操作,在发生视角调节按钮的触发操作时,判断接收到进入视角选择模式的控制信号;或者,在进入到虚拟现实系统的虚拟现实场景后,检测显示在虚拟现实场景中的视角调节控键是否发生触发操作,在发生视角调节控键的触发操作时,判断接收到进入视角选择模式的控制信号。
需要说明的是,对于视角调节按钮的触发操作和视角调节按键的触发操作本实施例不作具体限制。在具体实现时,可以将按压操作或旋动操作作为视角调节按钮的触发操作,将输入设备上发生按键操作作为视角调节按键的触发操作,如使视角调节按键的触发操作响应于蓝牙手柄上左移按键“←”、右移按键“→”、上移按键“↑”和下移按键“↓”等按键上的按压操作。
S120,在进入视角选择模式后,判断是否接收到位置调整信号,在接收到位置调整信号时,同步移动左虚拟显示屏幕和右虚拟显示屏幕的位置,或者,同步移动左虚拟显示屏幕的左视角位置和右虚拟显示屏幕的右视角位置。
在具体实现时,可以使左右虚拟显示屏幕的同步移动或左右视角位置的同步移动响应于蓝牙手柄上左移按键“←”、右移按键“→”、上移按键“↑”和下移按键“↓”等按键上的按压操作,如在蓝牙手柄上按压右移信号“→”时,左右虚拟显示屏幕同步右移或左右视角位置同步右移。
显然,位置调整信号也可以响应于其他操作,如响应于触摸屏幕上发生的滑动操作。本实施例对位置调整信号的触发操作不做具体限定。
S130,将移动位置后左视角范围内的左虚拟显示屏幕上的内容绘制为相应于左眼的左眼图像,右视角范围内的右虚拟显示屏幕上的内容绘制为相应于右眼的右眼图像,并将左眼图像和所述右眼图像同步发送到虚拟现实系统的显示设备进行分屏显示,实现对虚拟现实系统的视角调节。
本实施例通过设置视角选择模式的控制信号和位置调整信号,使得在进入虚拟现实系统 的视角选择模式后,可以根据位置调整信号同步移动左右虚拟显示屏幕或同步移动左右视角位置,使用户根据自身情况适应调节虚拟现实系统的视角,增强用户体验。
本实施例实现了用户对虚拟现实环境的高度定制化需求,使得用户可以随心所欲的调整观察虚拟现实场景的视角位置,由于用户在每个视角位置都能有不同的虚拟现实感受,从而保证了完整的用户体验,有效地增加了用户粘度。
实际应用中,在同步移动左虚拟显示屏幕和右虚拟显示屏幕的位置,或者,同步移动左虚拟显示屏幕的左视角位置和右虚拟显示屏幕的右视角位置后,图1中的方法还包括:
判断是否接收到退出视角选择模式的确认信号,在接收到退出视角选择模式的确认信号时,退出视角选择模式,并分别记录下当前左虚拟显示屏幕和右虚拟显示屏幕的视角位置,便于用户再次进入虚拟现实系统的虚拟现实场景时,直接将视角定位至已记录的位置。
其中,本实施例进一步地通过下述方法判断是否接收到退出视角选择模式的确认信号:
检测是否发生视角调节按钮的再次触发操作,在发生视角调节按钮的再次触发操作时,判断接收到退出视角选择模式的确认信号;或者,检测显示在所述虚拟现实场景中的确认控键是否发生触发操作,在发生确认控键的触发操作时,判断接收到退出视角选择模式的确认信号。即退出视角选择模式的确认信号也可以响应于实体按钮的触发操作,或者响应于虚拟按键的触发操作。
本实施例通过下述具体实现方案说明虚拟现实系统视角的调节方法。如图2所示,在虚拟现实系统的虚拟现实场景中构建两个大小、形状和位置完全相同的左虚拟显示屏幕和右虚拟显示屏幕,其中,左虚拟显示屏幕显示的内容与右虚拟显示屏幕显示的内容具有视差,以实现3D效果。需要说明的是,为便于观看,图2中将左虚拟显示屏幕和右虚拟显示屏幕并排显示,实际上左虚拟显示屏幕和右虚拟显示屏幕的位置应完全重合。
用户在进入虚拟现实系统的虚拟现实场景后,设置一默认观影位置作为初始视角位置,如图2所示,将左虚拟显示屏幕(或右虚拟显示屏幕)正前方位置作为初始视角位置。需要说明的是,左虚拟显示屏幕的左视角和右虚拟显示屏幕右视角的中心点位于两个虚拟显示屏幕的正前方,其中左视角和右视角间满足视差规定,本实施例示例性通过两个矩形表示左视角和右视角。
本具体实现方案中的虚拟现实系统的显示设备上设置有一个视角调节按钮,用户在点击此视角调节按钮后,便进入虚拟现实系统的视角选择模式。在此模式中,用户可以通过蓝牙手柄等输入设备,可以对左视角和右视角的位置进行同步移动。一般的,蓝牙手柄等输入设备都会有上、下、左、右的四个方向键,用户通过操作蓝牙手柄的方向键实现左视角和右视角位置的前、后、左、右的移动。
当用户将视角调整至最舒适的位置后,再次点击此视角调节按钮,退出视角选择模式并且记录当前的位置,以便于用户再次进入虚拟现实系统的虚拟现实场景时,直接将视角定位至已记录的位置。
