下面对上述相机的参数确定方法进行详细介绍。
参见图1，图1为本申请实施例提供的一种相机的参数确定方法的流程示意图，该方法包括如下步骤S101-S103：
S101，获得用于模拟目标场景的场景模型，在场景模型中部署虚拟相机。
其中，上述目标场景指的是：待部署相机的、真实的场景，例如，上述目标场景可以是以下场景中的任一种：小区、施工现场、交通路口、工厂、商场等。
上述虚拟相机指的是：用于模拟真实相机的模型，上述虚拟相机可以包括以下虚拟的相机中的一种或多种：枪机、球机、广角相机、鱼眼相机等。
具体的，可以利用三维建模技术，获得目标场景的三维模型，作为场景模型，并在上述场景模型中部署一个或多个虚拟相机，从而模拟在实际的目标场景中部署真实的相机。
S102，根据虚拟相机的虚拟参数模拟虚拟相机在场景模型中进行布控，得到模拟监控 图像。
其中，虚拟参数包括虚拟部署参数和虚拟配置参数。
上述虚拟部署参数指的是以下参数中的至少一个：虚拟相机在场景模型中的安装位置、高度、朝向、安装方式等，上述安装方式包括以下方式中的任一种：壁装、吊装、安装在立杆上等。
上述虚拟配置参数指的是相机自身的参数，包括以下参数中的至少一个：焦距、监控模式、垂直视场角、水平视场角等。上述监控模式至少包括走廊模式、正常模式。
上述走廊模式指的是：将相机所采集的图像进行90°旋转，提高相机在纵向方向上的监控范围，例如，假设相机所采集的图像的宽高为1920*1080，旋转90°之后，所采集的图像的宽高即为1080*1920。
上述正常模式指的是：不对相机所采集的图像进行旋转。
上述模拟监控图像指的是：模拟虚拟相机能拍摄到的场景模型中的监控图像。
具体的，可以根据虚拟相机自身的配置参数、以及在场景模型中的部署参数，模拟虚拟相机在场景模型中布控，从而模拟得到虚拟相机采集的图像，作为模拟监控图像，该图像可以反映虚拟相机在场景模型中的监控范围。
S103，在模拟监控图像满足监控需求的情况下，将虚拟相机的虚拟部署参数和/或虚拟配置参数，确定为目标场景中待部署的相机的参考部署参数和/或参考配置参数。
其中，上述监控需求指的是：针对相机监控范围的需求，例如，可以是以下需求中的至少一种：目标物位于监控范围内、目标通道位于监控范围内等，上述目标物可以是用户关注的、需要进行监控的物体，例如，可以是以下物体中的至少一种：收银机、卡口闸机、贵重物品柜台等，同样地，上述目标通道可以是用户关注的、需要进行监控的通道，例如是以下通道中的至少一种：消防通道、客流通行通道等。
具体的，模拟监控图像可以反映虚拟相机的监控范围，根据上述模拟监控图像，可以判断虚拟相机的监控范围是否满足监控需求，若为是，则说明当前虚拟相机的虚拟部署参数、虚拟配置参数适用于该场景模型，因此，一方面可以将当前虚拟相机的虚拟部署参数确定为目标场景中待部署的相机的参考部署参数，从而后续可以基于上述参考部署参数，将所选择的相机部署在场景模型中；
另一方面，可以将当前虚拟相机的虚拟配置参数确定为目标场景中待部署的相机的参考配置参数，从而后续可以基于该参考配置参数选择目标场景中待部署的相机的类型。这样利用虚拟部署参数可以指导实际在目标场景中安装相机，保证安装后相机满足监控需求。
本申请的一个实施例中，当仅需要推荐相机时，可以在模拟监控图像满足监控需求的情况下，将虚拟相机的虚拟配置参数，确定为目标场景中待部署的相机的参考配置参数，后续可以按照上述参考配置参数进行相机推荐。例如，在相机采购的场景中，为了向用户推荐所需采购的相机的类型，可以按照上述方案，确定参考配置参数，以便于用户采购与该参考配置参数相匹配的相机。
相应地，当仅需要对相机的部署进行指导时，可以在模拟监控图像满足监控需求的情况下，将虚拟相机的虚拟部署参数，确定为目标场景中待部署的相机的参考部署参数。例 如，在相机部署的场景中，可以按照上述参考部署参数，将待部署的相机部署在场景中。
本申请的一个实施例中，在判断虚拟相机对应的模拟监控图像是否满足监控需求时，可以对上述模拟监控图像进行展示，接收用户通过外部输入设备输入的指令，该指令携带满足监控需求或不满足监控需求的信息，上述满足监控需求的信息指的是：表征用户认为模拟监控图像满足监控需求的信息，上述不满足监控需求的信息指的是：表征用户认为模拟监控图像不满足监控需求的信息。根据上述指令可以判断模拟监控图像是否满足监控需求。其中，上述外部输入设备可以是以下设备中的任一种：键盘、鼠标、触摸板、麦克风。
除此之外，在判断虚拟相机对应的模拟监控图像是否满足监控需求时，还可以对模拟监控图像进行目标检测，基于检测结果判断模拟监控图像的图像内容中是否包含完整的目标对象，若为是，则说明虚拟相机的监控范围覆盖完整的目标对象，进而认为满足监控需求，否则，说明虚拟相机的监控范围难以覆盖完整的目标对象，进而认为不满足监控需求。其中，上述目标对象为预设的需要监控的对象，例如，上述目标对象可以是出入口、收银台、货架等。
上述实施例提供的方案中，可以获得用于模拟目标场景的场景模型，在场景模型中部署虚拟相机；根据虚拟相机的虚拟参数模拟虚拟相机在场景模型中进行布控，得到模拟监控图像，其中，虚拟参数包括虚拟部署参数和虚拟配置参数；在模拟监控图像满足监控需求的情况下，将虚拟相机的虚拟部署参数和/或虚拟配置参数，确定为目标场景中待部署的相机的参考部署参数和/或参考配置参数。这样可以在场景模型中部署虚拟相机，根据虚拟相机的虚拟参数模拟得到监控图像，根据所模拟的监控图像判断虚拟相机的虚拟参数是否满足监控需求，若为是，则可以将该虚拟相机的虚拟部署参数和/或虚拟配置参数确定为实际在目标场景中所要部署的相机的参考部署参数和/或参考配置参数，后续可以基于该参考部署参数和/或参考配置参数确定实际在目标场景中所要部署的相机的部署参数和/或配置参数，从而保证所确定的相机的参数与真实的目标场景相匹配。由此可见，应用上述实施例提供的方案，可以提高所确定的相机参数的准确度。
本申请的一个实施例中，在模拟监控图像不满足监控需求的情况下，调整虚拟相机的虚拟部署参数和/或虚拟配置参数，返回步骤S102，直至模拟监控图像满足监控需求。
具体的，模拟监控图像可以反映虚拟相机的监控范围，根据上述模拟监控图像，可以判断虚拟相机的监控范围是否满足监控需求，若为否，则可以调整虚拟相机的虚拟部署参数和/或虚拟配置参数，基于调整后的参数，重新获得参数调整后的虚拟相机对应的模拟监控图像，再次判断参数调整后虚拟相机的模拟监控图像是否满足监控需求，直至所得到的模拟监控图像满足监控需求。
本申请的一个实施例中，在调整虚拟相机的虚拟参数时，可以接收用户通过外部输入设备输入的调整指令，按照该调整指令调整虚拟相机的虚拟部署参数和/或虚拟配置参数。
除此之外，也可以按照预设的调整步长调整虚拟相机的虚拟部署参数和/或虚拟配置参数。例如，假设待调整的参数为焦距，预设的调整步长为1米，则在每一次调整虚拟相机的焦距时，可以将虚拟相机的焦距上调1米。
本申请的一个实施例中，场景模型中可以部署有多个虚拟相机，这种情况下，可以确 定不同虚拟相机的视场范围之间的监控盲区；根据所确定的监控盲区，调整多个虚拟相机中至少一虚拟相机的虚拟部署参数和/或虚拟配置参数。
具体的，可以检测上述多个虚拟相机的监控区域中是否存在盲区，若为是，则可以根据所确定的盲区，对上述多个虚拟相机中的至少一个虚拟相机的虚拟参数进行调整。这样根据不同虚拟相机之间的盲区对至少一虚拟相机的虚拟部署参数和/或虚拟配置参数进行调整，以使得参数调整后不同虚拟相机之间不存在监控盲区，进而保证后续基于虚拟相机的虚拟部署参数和/或虚拟配置参数所得到的待部署的相机的参考部署参数和/或参考配置参数与实际的目标场景更加匹配，提高后续实际部署的相机的监控效果。
本申请的一个实施例中，在确定不同虚拟相机的视场范围之间的监控盲区时，可以根据上述多个虚拟相机对应的模拟监控图像，确定不同虚拟相机的视场范围之间的监控盲区。
具体的，每一虚拟相机对应的模拟监控图像可以反映该虚拟相机的范围，在存在多个虚拟相机的情况下，可以根据上述多个虚拟相机对应的模拟监控图像所反映的监控区域，确定上述多个虚拟相机的监控区域之间的监控盲区。
除此之外，也可以根据各个虚拟相机的虚拟部署参数和虚拟配置参数，直接确定各个虚拟相机的监控区域，进而获得各个虚拟相机的监控区域之间的盲区，得到不同虚拟相机的视场范围之间的监控盲区。
另外，也可以直接接收用户通过外部输入设备输入的监控盲区，本申请实施例并不对此进行限定。
本申请的一个实施例中，在获得模拟监控图像时，可以根据虚拟相机的虚拟部署参数，确定虚拟相机的视场方向，沿视场方向对场景模型进行投影，得到投影图像；根据虚拟相机的虚拟部署参数和虚拟配置参数，确定虚拟相机的视场范围，根据视场范围对投影图像进行裁剪，得到裁剪后的模拟监控图像。
具体的，基于虚拟相机的虚拟部署参数，可以确定虚拟相机的安装位置和朝向，从而得到虚拟相机的视场方向，沿该视场方向对场景模型进行投影，可以得到投影图像，再根据虚拟相机的虚拟部署参数和虚拟配置参数，可以得到虚拟相机的视场范围，按照该视场范围对上述投影图像进行裁剪，从而得到裁剪后的图像，该图像即为所模拟的虚拟相机采集的模拟监控图像。
除此之外，本申请的一个实施例中，也可以直接根据虚拟相机的虚拟部署参数和虚拟配置参数，确定虚拟相机的视场范围及视场方向，然后沿上述视场范围对场景模型进行分割，得到处于虚拟相机的视场范围的局部场景模型，然后沿虚拟相机的视场方向对上述局部场景模型进行投影，得到虚拟相机对应的模拟监控图像。
本申请的一个实施例中，在步骤S103确定虚拟相机的虚拟配置参数为目标场景中待部署的相机的参考配置参数之后，还可以：
从预先获得的不同型号的相机类型中，确定配置参数与参考配置参数相匹配的推荐相机类型。
具体的，实际的各种型号的相机中，可能不存在与上述参考配置参数完全一致的相机，鉴于此，为了向用户推荐合适的相机类型，可以预先获得不同型号的相机的相机类型、以 及不同相机类型的相机的配置参数，然后从中确定配置参数与该参考配置参数相匹配的相机类型，作为推荐在目标场景中安装的相机的推荐相机类型。这样便于用户按照所推荐的相机类型，选择实际在目标场景中所部署的相机。
本申请的一个实施例中，在确定配置参数与参考配置参数相匹配的推荐相机类型时，可以选择配置参数与参考配置参数之间的差异最小的相机类型，作为推荐相机类型；
除此之外，也可以选择配置参数覆盖参考配置参数的相机类型，作为推荐相机类型。例如，假设参考配置参数中水平视场角为60°，则可以选择水平视场角大于等于60°的相机类型，作为推荐相机类型。
本申请的一个实施例中，在确定推荐相机类型时，可以根据虚拟相机的参考配置参数，确定与该参考配置参数相匹配的多个推荐相机类型，接收用户对上述多个推荐相机类型中的选中操作，将用户所选中的相机类型作为实际需要的目标相机类型。这样可以由电子设备确定出至少一个推荐相机类型，然后由用户从上述多个推荐的相机类型中选择实际需要的目标相机类型。
本申请的一个实施例中，在得到推荐相机类型之后，还可以：
针对任一推荐相机类型，根据该推荐相机类型对应的相机的配置参数，更新虚拟相机的虚拟配置参数，执行步骤S102。
具体的，针对任一推荐相机类型，可以得到该推荐相机类型对应的相机的配置参数，然后将虚拟相机的虚拟配置参数更新为该推荐相机类型对应的相机的配置参数，返回步骤S102，从而得到新的模拟监控图像，该模拟监控图像可以反映所推荐的相机类型对应的相机在实际应用中的监控范围，便于用户对所推荐的相机进行调整，避免由于所推荐的相机类型对应的相机的配置参数与参考配置参数不匹配，导致推荐的相机类型与目标场景不匹配。
例如，假设所确定的参考配置参数中垂直视场角为90°，而由于已有的相机中最大的垂直视场角为75°，这样使得所推荐的相机类型对应的相机的垂直视场角无法达到90°，从而采用所推荐的相机类型对应的相机进行布控时，可能导致相机的模拟监控图像不满足监控需求。在上述方案中，基于推荐相机类型对应的相机的配置参数对虚拟相机的虚拟配置参数进行更新，进而获得新的模拟监控图像，通过该模拟监控图像便于用户判断所推荐的相机类型对应的相机是否满足监控需求，以便于对所推荐的相机类型进行调整，提高所推荐的相机类型的可靠度。
本申请的一个实施例中，在基于推荐相机类型对应的相机的配置参数对虚拟相机的虚拟配置参数进行更新时，一种情况下，可以仅调整虚拟相机的虚拟配置参数，即仅将虚拟相机的虚拟配置参数更新为推荐相机类型对应的相机的配置参数，而不改变虚拟相机的虚拟部署参数；另一种情况下，可以对虚拟相机的虚拟配置参数、虚拟部署参数进行同步调整，即不仅将虚拟相机的虚拟配置参数更新为推荐相机类型对应的相机的配置参数，而且调整虚拟相机的虚拟部署参数，直至所得到的模拟监控图像满足监控需求，这样可以使得调整后虚拟相机的配置参数与部署参数更加匹配，进而提高相机的监控效果。
本申请的一个实施例中，在由任一推荐相机类型对应的相机的配置参数作为当前虚拟 配置参数得到的模拟监控图像满足监控需求的情况下，确定该推荐相机类型为目标相机类型。
具体的，在将虚拟相机的虚拟配置参数更新为所推荐的推荐相机类型对应的相机的配置参数后，返回上述步骤S102，重新得到模拟监控图像，判断所得到的模拟监控图像是否满足监控需求，若满足，则说明所推荐的推荐相机类型与目标场景相匹配，则可以将该推荐相机类型作为实际在目标场景中部署的相机的目标相机类型。
本申请的一个实施例中，在由任一推荐相机类型对应的相机的配置参数作为当前虚拟配置参数得到的模拟监控图像满足监控需求的情况下，还可以确定当前虚拟相机的虚拟部署参数为目标部署参数。
具体的，在由任一推荐相机类型对应的相机的配置参数作为当前虚拟配置参数得到的模拟监控图像满足监控需求的情况下，可以确定该推荐相机类型为目标相机类型，并确定当前虚拟相机的虚拟部署参数为目标部署参数，后续可以按照该目标部署参数，将所确定的目标相机类型对应的相机部署在目标场景中。这样可以保证所部署的相机的类型和部署参数相匹配，从而提高相机在目标场景中的监控效果。
除此之外，在上述方案的基础上，在由任一推荐相机类型对应的相机的配置参数作为当前虚拟配置参数得到的模拟监控图像满足监控需求的情况下，还可以获得当前虚拟相机的虚拟配置参数作为目标配置参数。
具体的，在由任一推荐相机类型对应的相机的配置参数作为当前虚拟配置参数得到的模拟监控图像满足监控需求的情况下，可以确定该推荐相机类型为目标相机类型，并将当前虚拟相机的虚拟配置参数作为目标配置参数、将当前虚拟相机的虚拟部署参数作为目标部署参数，这样后续可以按照该目标部署参数，将所确定的目标相机类型对应的相机部署在目标场景中，并按照目标配置参数对所部署的相机进行参数配置，例如，假设目标相机类型对应的相机支持的焦距为6米-12米，而所确定的目标配置参数中焦距为10米，则可以将目标相机类型对应的相机的焦距配置为10米。这样能够使得所部署的相机与目标场景更匹配，提高相机的监控效果。
