具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本公开可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本公开范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开至少一个实施例提供了一种用于确定图像采集设备位置的方法，请参照附图1，其示出了该方法的流程，包括步骤S101至步骤S103。
其中，该方法可以由终端设备或服务器等电子设备执行，终端设备可以为用户设备(User Equipment，UE)、移动设备、终端、蜂窝电话、无绳电话、个人数字处理(Personal Digital Assistant，PDA)手持设备、计算设备、车载设备、可穿戴设备等，该方法可以通过处理器调用存储器中存储的计算机可读指令的方式来实现。或者，可以通过服务器执行该方法，服务器可以为本地服务器、云端服务器等。
在步骤S101中，获取待布置区域的路网信息和重点位置信息。
本步骤中，可以在导入包含待布置区域的地图和预设的重点位置列表后，获取包 含所述待布置区域的地图和预设的重点位置信息，以及获取所述地图中的各条道路对应的标识线以及标识线之间的交点，作为所述待布置区域的路网信息。
其中，可以预先下载待布置区域的地图数据(例如，ZY-3卫星、GF-2卫星全色多光谱RGB、PGIS地图数据)以进行导入操作，或者直接针对商业地图进行导入操作。重点位置可以包括待布置区域内的重点防范目标，例如机关、医院、电站、学校等重要区域和酒店、酒吧、歌厅等案发风险较高的场所。
其中，可以通过路网提取等智能视频图像计算服务提取道路的标识线，例如可以先进行道路检测，获得道路分割掩膜，然后在道路分割掩膜的基础上，提取各条道路的中心线，基于影像地理信息或图像坐标，对道路中心线进行矢量化，得到每条道路的矢量线作为道路的标识线。
在步骤S102中，针对所述待布置区域，根据布局策略的区域等级确定区域等级范围。
其中，布局策略可以预先根据输入的策略生成操作而确定，策略生成操作例如可以由用户输入或计算机自动生成。布局策略包括区域等级和位置配比，其中，所述区域等级包括逐级缩小的包围圈、分隔块、网格、主干道和重点位置中的至少一个，所述位置配比包括脸部卡口和视频图像采集设备的配比。通过根据图像采集设备的布局需求生成对应的布局策略，以及通过预先设置该布局策略，使后续依据该布局策略所标注的区域以及确定的图像采集设备布点位置能够满足布局需求，使图像采集设备能够在适当的位置发挥较大作用。
执行该方法的终端可以根据布局策略确定区域等级范围，例如提示用户依据布局策略中的区域等级输入标注操作，并获取依据不同区域等级输入的区域等级范围，标注操作为确定一个区域等级的区域范围的操作。例如，区域等级包括包围圈、分隔块、网格、主干道和重点位置，则终端依次提示用户依据各个区域等级输入标注操作，并在每个区域等级划分阶段根据标注操作确定该区域等级对应的区域等级范围。终端可以生成提示用户输入依据包围圈这一区域等级的标注操作，用户根据提示在地图上画一个包围圈，则该包围圈对应的范围确定为包围圈的区域等级范围，其他区域等级的区域等级范围的确定也是类似的流程，这里不再进行一一赘述。
在步骤S103中，根据所述区域等级范围、所述路网信息和所述重点位置信息确定所述图像采集设备布点位置。
其中，根据区域等级范围，再进一步结合路网信息和重点位置信息，能够兼顾全面布点和重点布点两个方面，从而使布点位置准确可靠。
除了根据区域等级范围、路网信息和重点位置，确定图像采集设备布点位置，还可以同时确定每个图像采集设备布点位置的方向。
根据上述实施例可知，通过获取待布置区域的路网信息和重点位置信息后，针对所述待布置区域，根据布局策略的区域等级确定区域等级范围，以及根据所述区域等级范围、所述路网信息和所述重点位置信息确定图像采集设备布点位置。由于确定图像采集设备布点位置时结合了区域等级范围以及路网信息和重点位置信息，在关注重点位置 的同时顾及了待布置区域的全局，诸如包围圈、分隔块、网格、主干道等区域，因此可以同时提高重点位置和整个区域的图像采集效果。
本公开的一些实施例中，所述区域等级包括包围圈、分隔块、网格、主干道和重点位置中的至少一个，其中，包围圈、分隔块、网格、主干道和重点位置的区域等级逐渐降低。
基于此，可以按照下述方式根据所述区域等级范围、所述路网信息和所述重点位置信息确定所述图像采集设备布点位置：
在划定包围圈的范围的界面，获取依据包围圈的标注，例如用户在某个城市的边界划定一个包围圈，在城市的主城区划定内外两个包围圈，从而可以确定包括一个或多个包围圈的区域等级范围。则可以响应于在所述待布置区域内依据包括一个或多个包围圈，确定所述一个或多个包围圈的第一边界标识线，将所述第一边界标识线与所述各条道路对应的标识线的交点确定为图像采集设备布点位置。在所述包围圈的第一边界标识线和各道路对应的标识线的交点处设置图像采集设备布点位置，能够在被追踪对象等出入该包围圈时被图像采集设备监控到，从而便于锁定该被追踪对象的行动轨迹，因此将该位置设置为图像采集设备布点位置较为合理有效。交点的位置可以以经纬度进行记录。请参照附图2，其示例性的示出了包围圈的示意图。
在划定分隔块的范围的界面，获取依据分隔块的标注，例如用户借以天然屏障将某个城市划分为多个分隔块，并以手动方式在地图上标注该分隔块的范围和编号，从而可以确定包括一个或多个分隔块的区域等级范围。则可以响应于在所述待布置区域内包括一个或多个分隔块，确定所述一个或多个分隔块的第二边界标识线，将所述第二边界标识线与所述各条道路对应的标识线的交点确定为所述图像采集设备布点位置。在所述分隔块的第二边界标识线和道路对应的标识线的交点处设置图像采集设备布点位置，能够在被追踪对象等出入该分隔块时被图像采集设备监控到，从而便于锁定该被追踪对象的行动轨迹，因此将该位置设置为图像采集设备布点位置较为合理有效。交点的位置可以以经纬度进行记录。请参照附图3，其示例性的示出了分隔块的示意图。
在划定网格的范围的界面，获取依据网格的标注，例如用户将某个城市的村庄或社区划分为独立的网格，并以手动方式在地图上标注各网格的范围和编号，从而可以确定包括一个或多个网格的区域等级范围。则可以响应于在所述待布置区域内包括一个或多个网格，确定所述一个或多个网格的第三边界标识线，将所述第三边界标识线与所述每条道路对应的标识线的交点确定为所述图像采集设备布点位置。在所述网格的第三边界标识线和道路对应的标识线的交点处设置图像采集设备布点位置，能够在被追踪对象等出入该网格时被图像采集设备监控到，从而便于锁定该被追踪对象的行动轨迹，因此将该位置设置为图像采集设备布点位置较为合理有效。交点的位置可以以经纬度进行记录。请参照附图4，其示例性的示出了网格的示意图。
在划定主干道的界面，获取依据主干道的标注，例如用户在步骤S101中提取出的各个道路对应的标识线中，选择其中的国道、省道、县道、街道和巷道中的至少一种为主干道。则可以响应于在所述待布置区域内包括一个或多个主干道，根据所述一个或多个主干道的标识线确定所述图像采集设备布点位置。
在一些实施例中，响应于在所述待布置区域内包括一个或多个主干道，从所述各条道路对应的标识线中确定所述一个或多个主干道对应的标识线；从所述一个或多个主干道对应的标识线中确定关键干道对应的标识线，其中，所述关键干道的标识线为与所述一个或多个包围圈的第一边界标识线存在交点的标识线；将不同的所述关键干道对应的标识线之间的交点确定为所述图像采集设备布点位置。在不同的关键干道的标识线之间的交点处设置图像采集设备布点位置，能够在被追踪对象通过关键干道从包围圈内向包围圈外移动的过程中被图像采集设备监控到，从而便于锁定该被追踪对象的行动轨迹，因此将该位置设置为图像采集设备布点位置较为合理有效。交点的位置可以以经纬度记录。请参照附图5，其示例性的示出了关键干道的示意图。
在确定重点位置的界面，获取依据重点位置的标注，例如，可以从导入的重点位置列表中选择标注的重点位置，则在地图上自动标注该重点位置。则可以响应于在所述待布置区域内依据获取到的所述重点位置信息进行标注操作，在所述重点位置周围预设的距离范围内确定至少一个所述图像采集设备布点位置。
在一些实施例中，针对所述一个或多个重点位置中的每个，获取与该重点位置相连(例如相切或连通)的道路的标识线；在该重点位置周围预设的距离范围内，基于与该重点位置相连的道路的标识线上距离该重点位置最近的交点以及该重点位置，确定所述图像采集设备布点位置，其中，所述距离该重点位置最近的交点为不同的道路的标识线之间的交点。例如，可以将所述重点位置对应的出入口、邻近广场和最近的交点中的至少一个，确定为图像采集设备布点位置，其中，所述邻近广场为与所述重点位置的距离小于预设的距离阈值的广场。通过在上述三个位置设置图像采集设备，能够对重点位置形成包围，从而在待跟踪对象从重点位置进出时被锁定，因此上述三个位置设置为图像采集设备布点位置较为合理有效。可以提取上述三个位置的经纬度作为位置信息。
另外，在确定图像采集设备布点位置后，还可以确定所述图像采集设备布点位置对应的图像采集方向。例如，在包围圈的第一边界标识线与道路的标识线的交点位置，可以确定沿该道路行进的至少一个方向(进或者出所述包围圈的方向)为该位置对应的图像采集方向；在分隔块的第二边界标识线与道路的标识线的交点位置，可以确定该道路的至少一个方向为该位置对应的图像采集方向；在网格的第三边界标识线与道路的标识线的交点位置，可以确定该道路的至少一个方向为该位置对应的图像采集方向；在不同关键干道的交点位置，可以将至少一个关键干道的至少一个方向确定为该位置对应的图像采集方向，最多可设置四个图像采集方向；在重点位置的多个布点位置设置图像采集设备，例如在重点位置的出入口设置朝向重点位置内和/或外的图像采集设备，在邻近广场设置朝向重点位置的方向的图像采集设备，在根据所属道路信息的交点与重点位置的相对位置设置图像采集设备方向。
需要注意的是，在确定各个区域等级范围对应的图像采集设备布点位置后，均需要与之前确定的图像采集设备布点位置进行比较，以对所述图像采集设备布点位置中的重复位置进行去重处理。例如，相同经纬度和相同方向的图像采集设备位置作为同一个图像采集设备位置予以去除。通过去重处理能够增加图像采集设备布点位置的合理性。
需要注意的是，在确定各个区域等级范围对应的图像采集设备布点位置后，可以 与已布置图像采集设备的位置进行比较，以去除所述图像采集设备布点位置中与所述已布置图像采集设备的位置重复的位置。例如，相同经纬度和相同方向的图像采集设备位置作为同一个图像采集设备位置予以去除。通过去重处理能够增加图像采集设备布点位置的合理性。
本公开的一些实施例中，在确定图像采集设备布点位置后，还可以根据所述待布置区域内的以下参数确定风险评价指标：所述图像采集设备布点位置的数量、规划布点位置的数量和已布置图像采集设备的数量；并根据所述风险评价指标和预设的指标阈值，校正所述图像采集设备布点位置。
其中，可以统计通过步骤S103确定的图像采集设备布点位置的数量S(每个位置有多个方向的，每个方向记作一个位置，同一方向有多个摄像机记为一个位置)，统计已布置图像采集设备的数量E，本次规划位置数量F(例如可以是根据照财政资金投资额由规划公司按历史投资水平估算得到的)，通过下式计算风险评价指标H：
H＝100％*(E+F)/S。
可以预先设置指标阈值，例如设为80％。风险评价指标H是一个图像采集设备布置位置风险评价类的指标，应使风险评价指标H处于较高的数值，即高于或等于指标阈值的数值，若低于指标阈值，则应提高规划位置数量，或降低理论位置数量。
在一个示例中，响应于所述风险评价指标小于所述指标阈值，从所述图像采集设备布点位置中删除至少一个位置，直至所述风险评价指标大于或等于所述指标阈值。可以通过减少各个区域等级范围的数量，例如减少分隔块的数量、网格的数量等，从而减少图像采集设备布点位置的数量。
本实施例中，通过计算风险评价指标来校正上述图像采集设备布点位置，进一步提高了图像采集设备布点位置的科学性和合理性。
另外，在确定图像采集设备布点位置之后，可以按照下述方式补充盲点：首先，以每个重点位置为起点，以最外层的包围圈为终点，确定沿经过所述重点位置的道路对应的标识线从所述起点到所述终点的路径中的图像采集设备布点位置的数量；响应于所述路径中的所述图像采集设备布点位置的数量小于预设的数量阈值，在所述路径中增加至少一个布点位置，直至所述路径中的所述图像采集设备布点位置的数量大于或等于所述预设的数量阈值。其中，沿经过所述重点位置的道路对应的标识线从起点到终点的路径有多个，需要分别针对每个路径确定图像采集设备布点位置的数量，并根据每个路径的数量确定是否为该路径补充图像采集设备布点位置。数量阈值可以设置为2个，从而可以在其中1个图像采集设备出现故障时，另一个图像采集设备能够找到该路径中的被跟踪对象，提高了图像采集设备布点位置的有效性，同时又避免了图像采集设备滥布导致的成本浪费。
需要注意的是，当确定的图像采集设备布点位置被校正后，还可以按照上述步骤对盲点进行检测和补充。
通过对重点位置至包围圈的进行盲点的检测和补充，提高了图像采集设备的设置的合理性和有效性，避免了出现图像采集设备死角等盲点区域。
本公开的一些实施例中，在校正所述图像采集设备布点位置之后，还包括以下至少一个：在所述地图上标注所述图像采集设备布点位置；响应于导航需求，生成所述图像采集设备布点位置的导航方案；响应于接收到对所述图像采集设备布点位置对应的现实区域的修正，修正所述图像采集设备布点位置；或，响应于在所述图像采集设备布点位置对应的现实区域进行布置，确定所述现实区域处的图像采集设备类型，其中，所述图像采集设备类型为脸部卡口或视频采集设备。
在地图上标注图像采集设备布点位置，便于用户查看和确定位置。而针对布点位置生成的导航方案，能够指导现场勘察人员据此赶赴图像采集设备布点位置对应的现实区域，并在现实区域对现场安装环境、车道、路宽等工况环境进行勘察测绘，进而确定该位置是否合理，以及该位置的图像采集设备类型，即布置脸部卡口或视频采集设备。接收到现场勘测人员的操作后，可以修正该位置的位置信息或方向信息，并且确定该位置布置的图像采集设备类型。
另外，在确定了每个图像采集设备布点位置的图像采集设备类型后，可以按照下述方式确定脸部卡口和视频采集设备的比例是否合理：针对每个重点位置，以该重点位置为起点，以最外层的包围圈为终点，确定沿经过该重点位置的主干道对应的标识线从所述起点到所述终点的路径中的脸部卡口和视频采集设备的第一比例；针对所述图像采集设备布点位置中的每个，确定该图像采集设备布点位置中脸部卡口和视频采集设备的第二比例；响应于所述第一比例大于所述位置配比，或所述第二比例大于所述位置配比，调整所述图像采集设备布点位置中至少一个布点位置的图像采集设备类型，以使所述第一比例不大于所述位置配比，且所述第二比例不大于所述位置配比。其中，该位置配比在根据布局策略确定，例如可以由用户直接输入位置配比，例如可以是脸部卡口：视频图像采集设备为1:4。上述方式中，从重点位置到包围圈边界的主干道路径和每个图像采集设备布点位置两个维度来关注并调整位置配比，增加了位置配比的合理性，既能够保证图像采集设备效果，又避免成本浪费。
本公开的一些实施例中，在校正完成图像采集设备布点位置后，还可以提取所述图像采集设备布点位置的位置信息和对应的图像采集方向；在所述地图上分层显示各个区域等级对应的区域、图像采集设备布点位置的标识和对应的图像采集方向；和/或，生成图像采集设备布点位置列表，其中，所述列表内包括各个布点位置的标识和对应的图像采集方向。
其中，标识可以是编号等。可以在地图上分层展示包围圈(名称、边界线)、分隔块(编号、边界线)、网格(编号、边界线)、关键干道(编号、标识线)、重点位置(名称)、图像采集设备布点位置的编号及方向等。圈块格线点及选点的编号规则可以按照当地编号规范确定。
通过对不同区域等级以及图像采集设备布点位置的显示，能够便于用户查看结果，从而方便指导用户对图像采集设备的和布置决策和布置施工。
执行本实施例提供的用于确定图像采集设备位置的方法的系统能够自动确定出图像采集设备的布置位置，并计算投资效益最大化下图像采集设备布局的科学性的风险评价指数，提示图像采集设备位置布局后该区域依然存在的风险，同时也可以由设计人员 进行微调图像采集设备的布置位置。初步确定的图像采集设备的位置可以直接在地图上呈现，并可以结合GPS/北斗等进行点位导航，便于勘察人员赶赴现场对现场工况进行实地勘察和施工图纸测绘。
