综上所述，本申请所示方案，通过实时检测第一虚拟车辆与第二虚拟车辆之间的相对距离，确定其中的目标虚拟车辆，并且通过虚拟摄像机以目标虚拟车辆为焦点对虚拟场景进行拍摄，展示拍摄得到的辅助画面。由于第二虚拟车辆与第一虚拟车辆之间的相对距离可能会出现经常变化的情况，通过上述方案可以灵活的确定各个时刻对应的目标虚拟车辆，并且展示以目标虚拟车辆为焦点的辅助画面，从而使得辅助画面 能够尽可能的显示有效的画面，提高了辅助画面传递有益于用户操作的信息的效率，保证用户在正常观察虚拟车辆前方的画面的同时，也能够观察到车辆后方的有效的画面内容，从而提高用户控制虚拟车辆时的交互效率以及人机交互效率。
图5示出了本申请实施例示出的虚拟场景中画面展示方法流程图。其中，上述方法可以由计算机设备执行，该计算机设备可以是终端，也可以是服务器，或者，上述计算机设备也可以包含上述终端和服务器。如图5所示，以计算机设备是终端为例，终端可以通过执行以下步骤来在虚拟场景画面上展示辅助画面。

其中，该虚拟场景画面可以是包含第一虚拟车辆的，并且与其他虚拟车辆进行赛车比赛的虚拟场景。第一虚拟车辆是由该终端控制的虚拟车辆，其它虚拟车辆可以是其他终端控制的或者是AI控制的虚拟车辆。
在一些实施例中，该虚拟场景画面是根据该第一虚拟车辆的第三人称视角观察到的虚拟场景画面。其中，该第一虚拟车辆的第三人称视角是该第一虚拟车辆的后上方设置的主画面虚拟摄像头对应的视角，该第一虚拟车辆的第三人称视角观察到的虚拟场景画面是该第一虚拟车辆后上方设置的主画面虚拟摄像头观察到的虚拟场景画面。

在一些实施例中，虚拟场景画面是铺满展示在终端的显示区域中，该虚拟场景画面是控制第一虚拟车辆在虚拟场景中进行赛车比赛时的主显示画面，用于展示第一虚拟车辆在赛车比赛过程中的路径画面，用户通过获取到前方的路径画面对第一虚拟车辆进行操控。
其中，在虚拟场景画面上叠加有控件或者显示信息。
比如，控件可以包括用于接收触发操作控制第一虚拟车辆的移动方向的方向控件、用于接收触发操作控制第一虚拟车辆进行刹车的刹车控件以及用于控制第一虚拟车辆进行加速移动的加速控件等。而显示信息可以包括用于指示第一虚拟车辆以及其它虚拟车辆对应的账号身份标识，以及当前时刻各个虚拟车辆位置的先后顺序的排行信息、用于指示完整的虚拟场景的地图，以及简略的各个虚拟车辆在地图上的位置的地图信息等。
在一些实施例中，虚拟场景画面上叠加有视角切换控件，响应于用户对该视角切换控件的指定操作，虚拟场景画面可以在第一虚拟车辆的第一人称视角以及该第一虚拟车辆的第三人称视角之间切换。
例如，当终端显示的该虚拟场景画面是该第一虚拟车辆的第一人称视角对应的虚拟场景画面时，响应于用户对该视角切换控件的指定操作，该终端将该第一虚拟车辆的第一人称视角对应的虚拟场景画面切换为第三人称视角对应的虚拟场景画面；当终端显示的该虚拟场景画面是该第一虚拟车辆对应的第三人称视角对应的虚拟场景画面时，响应于用户对该视角切换控件的指定操作，该终端将该第一虚拟车辆的第三人称视角对应的虚拟场景画面切换为第一人称视角对应的虚拟场景画面。
在一些实施例中，同一用户账号对应的虚拟车辆可以是多个不同类型的虚拟车辆，终端响应于接收到服务器下发的虚拟车辆信息，在车辆选择界面上展示虚拟车辆信息对应的各个不同类型的虚拟车辆。响应于接收到用户对车辆选择界面的选择操 作，确定选择操作对应的目标虚拟车辆，并将目标虚拟车辆确定为第一虚拟车辆，同理，服务器接收到指定的虚拟场景标识，将对应的虚拟场景展示在终端上。
步骤502，获取第一虚拟车辆与第二虚拟车辆之间的相对距离。
在本申请实施例中，终端获取第一虚拟车辆与各个第二虚拟车辆之间的相对距离，第二虚拟车辆是位于第一虚拟车辆后方的虚拟车辆。
在一些实施例中，通过获取第一虚拟车辆的车尾参考线，将未超过该车尾参考线的区域确定为第一虚拟车辆的后方，且将位于第一虚拟车辆后方的各个虚拟车辆确定为第二虚拟车辆。
其中，第一虚拟车辆的车尾参考线是第一虚拟车辆的车尾所在直线，并且该车尾参考线与虚拟场景中的水平面平行，且与第一虚拟车辆的车头和车尾的连线垂直。
在一些实施例中，将第一虚拟车辆的车尾与第二虚拟车辆的中心点之间的连线长度，确定为相对距离。
其中，第二虚拟车辆的中心点可以是该虚拟车辆的重心。并且计算得到的相对距离是指虚拟场景中的距离。
步骤503，基于第一虚拟车辆与至少一个第二虚拟车辆之间的相对距离，从第二虚拟车辆中确定目标虚拟车辆。
在本申请实施例中，终端基于确定的各个第二虚拟车辆与第一虚拟车辆之间的相对距离，判断该相对距离是否满足指定条件，当该相对距离满足指定条件时，确定该相对距离对应的第二虚拟车辆是目标虚拟车辆，若没有满足指定条件的相对距离，则当前时刻不存在目标虚拟车辆。
在一些实施例中，在同一时刻，只存在一个目标虚拟车辆，或者不存在目标虚拟车辆。
在一些实施例中，将同时满足与第一虚拟车辆之间的相对距离小于等于第一距离以及该相对距离最小的第二虚拟车辆，确定为目标虚拟车辆。
1)首先，获取待选虚拟车辆，从待选虚拟车辆中确定目标虚拟车辆。然后，将与第一虚拟车辆之间的相对距离最小的待选虚拟车辆，确定为目标虚拟车辆。
其中，待选虚拟车辆是与第一虚拟车辆之间的相对距离小于等于第一距离的第二虚拟车辆。该待选虚拟车辆可以是满足相对距离小于等于第一距离的条件的部分第二虚拟车辆的集合。
比如，若第一距离为100米，当获取到虚拟场景中的第一虚拟车辆后方与该第一虚拟车辆的相对距离小于等于100米的第二虚拟车辆具有虚拟车辆甲、虚拟车辆乙以及虚拟车辆丙时，获取虚拟车辆甲、虚拟车辆乙以及虚拟车辆丙为待选虚拟车辆。比较三个待选虚拟车辆分别与第一虚拟车辆之间的相对距离，若虚拟车辆甲对应的相对距离是60米、虚拟车辆乙对应的相对距离是30米、虚拟车辆丙对应的相对距离是100米，则将相对距离最小的虚拟车辆乙确定为目标虚拟车辆。
2)首先，获取与第一虚拟车辆之间的相对距离最小的第二虚拟车辆，然后，响应于第二虚拟车辆与第一虚拟车辆之间的相对距离小于等于第一距离，将第二虚拟车辆确定为目标虚拟车辆。
比如，当获取到虚拟场景中的第一虚拟车辆后方具有虚拟车辆甲、虚拟车辆乙以及虚拟车辆丙时，获取虚拟车辆甲、虚拟车辆乙以及虚拟车辆丙分别与第一虚拟车辆之间的相对距离，然后比较三个待选虚拟车辆分别与第一虚拟车辆之间的相对距离，若虚拟车辆甲对应的相对距离是105米、虚拟车辆乙对应的相对距离是110米、虚拟车辆丙对应的相对距离是120米，则确定相对距离最小的虚拟车辆是虚拟车辆甲，然后判断虚拟车辆甲是否小于等于第一距离，若第一距离是100米，则判断虚拟车辆甲 不符合，当前时刻不具有目标虚拟车辆。若第一距离是105米，则判断虚拟车辆甲符合小于等于第一距离的条件，确定当前时刻的目标虚拟车辆是虚拟车辆甲。
步骤504，获取目标镜头方向与车尾参考线之间的第一钝角。
在本申请实施例中，在第一虚拟车辆的斜上方具有用于拍摄辅助画面的虚拟摄像头，并且该虚拟摄像头随着第一虚拟车辆移动。终端获取该虚拟摄像头对应的目标镜头方向与第一虚拟车辆的车尾参考线之间的第一钝角。
其中，目标镜头方向是从虚拟摄像机指向目标虚拟车辆的中心点的方向，车尾参考线是第一虚拟车辆的车尾所在直线，并且车尾参考线与水平面平行，且与第一虚拟车辆的车头和车尾的连线垂直。
示例性的，图6是本申请实施例涉及的一种用于拍摄辅助画面的虚拟摄像头的设置位置示意图。如图6所示，当虚拟场景中具有第一虚拟车辆621以及目标虚拟车辆631时，通过俯视图可以确定虚拟摄像机611位于第一虚拟车辆621的右前方。若虚拟场景中具有第一虚拟车辆622以及目标虚拟车辆632时，通过侧视图可以确定虚拟摄像机612位于第一虚拟车辆622的前上方。
其中，该虚拟摄像机也可以位于第一虚拟对象的左前上方。
比如，图7是本申请实施例涉及的一种目标镜头方向与车尾参考线之间的钝角确定过程示意图。如图7所示，通过将第一虚拟车辆72的车尾与第二虚拟车辆73的中心点之间进行连线，确定第一虚拟车辆72与该第二虚拟车辆之间的相对距离76，通过判断相对距离可以确定该第二虚拟车辆是目标虚拟车辆73，通过第一虚拟车辆72的车尾，作平行于水平面，垂直于车头车尾连线的直线，将该直线获取为第一虚拟车辆72的车尾参考线75，然后通过虚拟摄像机71向目标虚拟车辆73的中心点进行连线，该连线的指向方向作为虚拟摄像机71的目标镜头方向74，其中，目标镜头方向74与第一虚拟车辆72的车尾参考线75之间相交形成了四个夹角，其中包括两个锐角以及两个钝角，且两个锐角的角度相同，两个钝角的角度相同，将其中的第一钝角77进行获取。
步骤505，响应于第一钝角小于等于第一角度，基于目标虚拟车辆的位置，确定虚拟摄像机的第一镜头方向。
在本申请实施例中，响应于终端获取到的第一钝角小于等于第一角度，则基于目标虚拟车辆的位置，确定虚拟摄像机的第一镜头方向，该第一镜头方向为虚拟摄像头实际拍摄虚拟场景的镜头方向。
在一些实施例中，响应于终端获取到的第一钝角小于等于第一角度，将第一镜头方向确定为目标镜头方向。
示例性的，图8是本申请实施例涉及的一种镜头方向确定过程的示意图。如图8所示，若第一角度83为165度，当目标虚拟车辆移动到图中虚线位置时，目标镜头方向与第一虚拟车辆82的车尾参考线之间相交形成的第一钝角的角度是165度，当目标虚拟车辆86处于如图所示位置时，此时目标镜头方向与第一虚拟车辆82的车尾参考线之间相交形成的是第一钝角84，将第一钝角84与第一角度83进行比较，可以确定该第一钝角84小于第一角度83，从而将第一镜头方向确定为目标镜头方向。
步骤506，响应于第一钝角大于第一角度，确定虚拟摄像机的第二镜头方向。
在本申请实施例中，若响应于终端获取到的第一钝角大于第一角度，则确定虚拟摄像机的第二镜头方向为虚拟摄像头实际拍摄虚拟场景的镜头方向。
在一些实施例中，第二镜头方向指向目标镜头方向与车尾指向方向之间，且第二镜头方向与车尾参考线之间的第二钝角的角度为第一角度，车尾指向方向是从第一虚拟车辆的车头指向车尾的方向。
示例性的，如图8所示，若第一角度83为165度，当目标虚拟车辆移动到图中虚线位置时，目标镜头方向与第一虚拟车辆82的车尾参考线之间相交形成的第二钝角的角度是165度，当目标虚拟车辆87处于如图所示位置时，此时目标镜头方向与第一虚拟车辆82的车尾参考线之间相交形成的是第一钝角85，将第一钝角85与第一角度83进行比较，可以确定该第一钝角85大于第一角度83，从而将第一镜头方向确定为第二钝角为第一角度时对应的目标镜头方向。
步骤507，响应于辅助画面展示在虚拟场景画面中，启动画面展示计时器。
在本申请实施例中，当开始在虚拟场景画面中展示辅助画面的同时，启动画面展示计时器。
其中，画面展示计时器用于记录辅助画面在虚拟场景画面中连续展示的时长，或者该画面展示计时器还可以用于记录具有同一焦点的辅助画面的展示时长。
在一些实施例中，响应于确定第二虚拟车辆中存在目标虚拟车辆，开始在虚拟场景画面中展示辅助画面，同时开始进行画面展示计时器的计时功能，对辅助画面的展示时长进行记录。
其中，辅助画面可以展示在虚拟场景画面上的任意区域，并且辅助画面的尺寸大小可以进行调节，用户可以在画面设置界面对辅助画面在虚拟场景画面上的位置以及辅助画面展示的尺寸大小进行自定义设置或者选择。
在一些实施例中，响应于存在目标虚拟车辆，通过画面展示计时器进行计时，若之后终端接收到反馈此时不存在目标虚拟车辆，则结束画面展示计时器的计时功能，并且重置该画面展示计时器。
比如，若某一时刻终端通过计算确定目标虚拟车辆，开始启动画面展示计时器，并进行计时，当持续确定该目标虚拟车辆的时长为3秒时，通过画面展示计时器进行计时的时长为3s，若经过5s后，该目标虚拟车辆超过第一虚拟车辆，并且经过计算未确定存在其他虚拟车辆符合条件作为目标虚拟车辆，则结束画面展示计时器的计时功能，并且将计时器的计时时长重置清零。
在一些实施例中，响应于虚拟场景画面的展示时间大于第三时长，在虚拟场景画面中展示辅助画面。
其中，开始展示虚拟场景画面的时刻通过计时器进行计时，当计时器记录的时长在第三时长内时，终端不进行判断目标虚拟对象，当计时器记录的时长超过第三时长后，终端开始实时检测确定目标虚拟车辆的步骤。
比如，以赛车游戏为例，当各个虚拟车辆进入对局中后，自动进行对局开始倒计时，当倒计时结束后正式进入赛车竞速计时模式，在开始赛车竞速计时模式时的第三时长以内，不进行辅助画面的展示，或者不进行目标虚拟车辆的计算确定步骤，当赛车竞速模式开始时长超过第三时长后，开始基于目标虚拟车辆展示辅助画面。
在一些实施例中，响应于所述第一虚拟车辆从开始移动的位置到当前位置之间的距离大于指定距离，在虚拟场景画面中展示辅助画面。
其中，由于在起点出发位置，各个虚拟车辆从同一起跑线上开始移动，所以在开始阶段可能存在目标虚拟对象变化频繁的现象，而上述两种方式均用于控制第一虚拟车辆在起点出发位置附近不进行辅助画面的展示，可以避免无意义的辅助画面展示，从而节约终端资源。
在一些实施例中，响应于目标虚拟车辆与第一虚拟车辆之间的相对距离小于等于第二距离，保持虚拟摄像机的镜头方向，在虚拟场景画面上展示通过虚拟摄像机拍摄的镜头方向上的辅助画面。
其中，当第一虚拟车辆与目标虚拟车辆之间的相对距离很近时，并且达到虚拟摄 像机的镜头对应的最小有效距离即第二距离时，此时虚拟摄像机的镜头停止跟随目标虚拟车辆的位置进行移动，并且保持静止不动，该虚拟摄像机的镜头焦点仍然是目标虚拟车辆，若目标虚拟车辆与第一虚拟车辆之间的相对距离变大时，大于第二距离时，则虚拟摄像头的镜头方向继续跟随目标虚拟车辆移动。
步骤508，响应于在辅助画面展示过程中，目标虚拟车辆从第一目标虚拟车辆切换为第二目标虚拟车辆，将画面展示计时器进行重置。
在本申请实施例中，当辅助画面已经开始展示在虚拟场景画面中时，在各个虚拟车辆移动的过程中，在第一虚拟车辆后方与该第一虚拟车辆相对距离最小的虚拟车辆发生变化，由第一目标虚拟车辆变为第二目标虚拟车辆时，需要将画面展示计时器进行重置清零。
其中，第一目标虚拟车辆和第二目标虚拟车辆是至少一个第二虚拟车辆中的任意两个。
在一些实施例中，目标虚拟车辆从第一目标虚拟车辆切换到第二目标虚拟车辆后，虚拟摄像机的焦点由第一目标虚拟车辆切换到第二目标虚拟车辆。
其中，当目标虚拟车辆从第一目标虚拟车辆切换到第二目标虚拟车辆后，辅助画面中展示的虚拟场景，由以第一目标虚拟车辆为焦点进行拍摄的画面切换为以第二目标虚拟车辆为焦点进行拍摄的画面。
示例性的，以赛车游戏为例，图9是本申请实施例涉及的一种辅助画面对应的焦点切换示意图。如图9所示，若第一虚拟车辆91的后方具有第一目标虚拟车辆93以及第二目标虚拟车辆94，在当前虚拟场景画面上展示辅助画面92，由于当前时刻第一目标虚拟车辆93与第一虚拟车辆之间的相对距离最小，所以该辅助画面92是以第一目标虚拟车辆93为焦点进行拍摄的画面。若之后某一时刻，第二目标虚拟车辆94超过第一目标虚拟车辆93，成为与第一虚拟车辆之间的相对距离最小的虚拟车辆，所以将虚拟摄像机的焦点切换为第二目标虚拟车辆进行画面拍摄。
在一些实施例中，辅助画面上添加有用于指示冲刺效果的线条图案。
比如，如图9所示，冲刺效果的线条图案95位于辅助画面92的边缘，通过添加冲刺效果的线条图案95，可以使用户的紧张感增强，从而提高了用户的操作体验。
步骤509，响应于画面展示计时器对应的时长达到第一时长，结束展示辅助画面。
在本申请实施例中，当终端获取到画面展示计时器记录的时长达到第一时长时，结束在虚拟场景画面上展示辅助画面。
也就是说，响应于在辅助画面展示过程中，目标虚拟车辆从第一目标虚拟车辆切换为第二目标虚拟车辆，将画面展示计时器进行重置，当虚拟摄像头的焦点持续维持在同一虚拟车辆上的时长达到第一时长时，才结束在虚拟场景画面上展示该辅助画面。
通过上述方案，可以解决在辅助画面展示过程中，实时调整作为焦点的虚拟车辆，并且可以通过流畅的画面连续进行展示。有益于用户在进行操作过程中，通过辅助画面获取后方虚拟车辆的有效位置信息。
步骤510，响应于第一钝角大于第一角度的持续时间达到第二时长，结束展示辅助画面。
在本申请实施例中，当目标镜头方向与车尾参考线之间的第一钝角大于第一角度的持续时间达到第二时长，同样可以结束展示辅助画面。
在一些实施例中，当虚拟摄像头的镜头方向转到最大角度时，此时目标虚拟车辆是部分在辅助画面或者完全不在辅助画面中的状态，所以为了使辅助画面尽可能展示有意义的画面内容，当虚拟摄像头的镜头方向转到最大角度的时间持续达到第二时长 时，结束展示辅助画面。
其中，该第二时长可以小于第一时长，即通过上述方式结束的辅助画面相对于步骤509所示方案，可以提前结束展示辅助画面。
比如，图10是本申请实施例涉及的一种目标镜头方向与车尾参考线之间的第一钝角大于第一角度时辅助画面的示意图。如图10所示，该第一虚拟车辆后方的目标虚拟车辆处于超车状态，并且该目标虚拟车辆对应的第一钝角大于第一角度，所以在展示的辅助画面1001中不存在目标虚拟车辆，仅包括赛道边缘的画面。利用辅助画面1001展示赛道边缘画面对用户的操作没有实际的增益，所以若依旧在展示时长达到第一时长时结束该辅助画面1001，会出现终端资源浪费的情况。
应用本申请实施例，通过实时检测第一虚拟车辆与第二虚拟车辆之间的相对距离，确定其中的目标虚拟车辆，并且通过虚拟摄像机以目标虚拟车辆为焦点对虚拟场景进行拍摄，展示拍摄得到的辅助画面。由于第二虚拟车辆与第一虚拟车辆之间的相对距离可能会出现经常变化的情况，通过上述方案可以灵活的确定各个时刻对应的目标虚拟车辆，并且展示以目标虚拟车辆为焦点的辅助画面，从而使得辅助画面能够尽可能的显示有效的画面，提高了辅助画面传递有益于用户操作的信息的效率，保证用户在正常观察虚拟车辆前方的画面的同时，也能够观察到车辆后方的有效的画面内容，从而提高用户控制虚拟车辆时的交互效率以及人机交互效率。
以虚拟场景为赛车游戏中的虚拟场景为例，请参考图11，其示出了本申请一个示例性的实施例提供的一种虚拟场景中画面展示方法的逻辑流程图，如图11所示，该逻辑流程可以包括以下步骤：
终端检测第一虚拟车辆的触发范围内是否具有其它虚拟车辆，其中，触发范围可以是在第一虚拟车辆的后方，且相对距离小于第一距离的范围，当检测到存在其它虚拟车辆在处罚范围内时，对第一虚拟车辆当前状态进行判断(S1101)。若判断第一虚拟车辆当前处于刚开局冲出起点的状态(S1102)，则不触发后视镜功能，其中该后视镜功能为展示辅助画面的功能(S1103)。若判断第一虚拟车辆当前不处于刚开局冲出起点的状态(S1104)，则确定触发后视镜功能(S1105)。然后，若通过实时检测确定目标虚拟车辆一直处于第一虚拟车辆的触发范围内(S1106)，则通过虚拟摄像头跟踪拍摄该目标虚拟车辆的画面(S1107)，若在拍摄中途目标虚拟车辆离开第一虚拟车辆对应的触发范围(S1108)，则控制虚拟摄像机脱离跟踪拍摄该目标虚拟车辆(S1109)，若该目标虚拟车辆离开触发范围后指定时间内(如3秒)返回第一虚拟车辆的触发范围内(S1110)，则继续控制该虚拟摄像机跟踪拍摄目标虚拟车辆的画面(S1111)。若辅助画面的展示时长已经达到指定的最大展示时长，比如可以是3秒，则控制关闭后视镜功能，并且结束展示辅助画面(S1112)。
应用本申请实施例，通过实时检测第一虚拟车辆与第二虚拟车辆之间的相对距离，确定其中的目标虚拟车辆，并且通过虚拟摄像机以目标虚拟车辆为焦点对虚拟场景进行拍摄，展示拍摄得到的辅助画面。由于第二虚拟车辆与第一虚拟车辆之间的相对距离可能会出现经常变化的情况，通过上述方案可以灵活的确定各个时刻对应的目标虚拟车辆，并且展示以目标虚拟车辆为焦点的辅助画面，从而使得辅助画面能够尽可能的显示有效的画面，提高了辅助画面传递有益于用户操作的信息的效率，保证用户在正常观察虚拟车辆前方的画面的同时，也能够观察到车辆后方的有效的画面内容，从而提高用户控制虚拟车辆时的交互效率以及人机交互效率。
