另外，为了更好地说明本公开，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本公开同样可以实施。在一些实例中，对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本公开的主旨。
图2示出根据本公开实施例的三维数据显示方法的流程图，所述三维数据显示方法可以由终端设备执行，终端设备可以为用户设备(User Equipment，UE)、移动设备、用户终端、终端、蜂窝电话、无绳电话、个人数字助理(Personal Digital Assistant，PDA)、手持设备、计算设备、车载设备、可穿戴设备等电子设备，所述方法可以通过电子设备的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。如图2所示，所述三维数据显示方法包括：
在步骤S11中，获取人体部位的三维扫描数据。
在一种可能的实现方式中，三维扫描数据可以是通过CT设备扫描人体部位所得到的三维数据，CT设备可以将扫描得到的三维扫描数据直接传输给上述电子设备，或还可以传输给后端服务器，由后端服务器发送给需要查看人体部位的切片图的电子设备等，对此本公开实施例不作限制。
其中，三维扫描数据中包括人体部位在三个维度的切片数据以及三个维度的切片数据对应于人体部位的切片位置信息。人体部位例如可以包括腹部、胸部、头部等部位，对此本公开实施例不作限制；切片数据可以理解为渲染人体部位的切片图所需的三维数据，切片数据可以是预设数据格式(例如vis3D格式)的三维数据，以便于电子设备渲染出切片图，切片位置信息包括人体部位内全部切片数据的切片位置。
其中，以三维坐标系来定义三个维度可以包括：X轴维度、Y轴维度以及Z轴维度，应理解的是，各个维度的切片数据的所属维度、切片位置等可以以CT设备自身定义的三维坐标系为基准，当然也可以根据实际需求投影到其它三维坐标系(例如显示三维切片模型时所构建的三维坐标系)中，以便于在电子设备的显示界面中渲染切片图，对此本公开实施例不作限制。
在步骤S12中，根据在三个维度上分别指定的目标切片位置以及切片位置信息，确定目标切片位置处的切片数据。
其中，目标切片位置可以理解为用户期望显示的切片图在人体部位的切片位置。在一种可能的实现方式中，用户可以在三维切片模型的三维坐标系中预先指定目标切片位 置，例如用户可以在三维坐标系的三个坐标轴上分别设置坐标位置，将设置的坐标位置作为目标切片位置。
在一种可能的实现方式中，为了使用户更便捷地查看不同目标切片位置处的切片图，可以在显示界面中提供用于调节目标切片位置的位置调节控件，用户可以利用位置调节控件，分别指定不同维度上的不同目标切片位置，从而便于用户查看不同维度下不同目标切片位置处的切片图。图3示出根据本公开实施例的一种位置调节控件的示意图，如图3所示，用户可以通过调节各个维度的“空心圆”在线段上的位置，实现分别指定三个维度上的目标切片位置。
如上所述，切片位置信息包括人体部位内全部切片数据的切片位置，那么根据三个维度上分别指定的目标切片位置以及切片位置信息，可以得到三个维度上分别指定的目标切片位置处的切片数据，便于之后利用三个维度上分别指定的目标切片位置，显示人体部位的三维切片模型。
在步骤S13中，根据目标切片位置处的切片数据，显示人体部位的三维切片模型，三维切片模型中包括：根据切片数据渲染得到的人体部位在目标切片位置处的切片图。
如上所述，切片数据可以理解为渲染切片图所需的三维数据，其中，根据目标切片位置处的切片数据，显示人体部位的三维切片模型，可以理解为，根据三个维度上的三个目标切片位置处的切片数据，在电子设备的显示界面中渲染出人体部位在目标切片位置处的切片图。应理解的是，本领域技术人员可以采用本领域已知的渲染技术，例如开源的three.js技术，实现根据切片数据渲染出切片图，对此本公开实施例不作限制。图4示出根据本公开实施例的一种三维切片模型的示意图，如图4所示，三维切片模型中包括三个维度的三个切片图。
应理解的是，通过上述步骤S11可以获取人体部位的至少一个三维扫描数据，例如同一个人的同一人体部位在不同时期的三维扫描数据，或不同人的同一人体部位的三维扫描数据，这样按照步骤S12-S13可以在显示界面中显示至少一个三维切片模型，可以便于用户同时对照人体部位的不同三维切片模型。
在本公开实施例中，通过在三个维度上指定的目标切片位置以及切片位置信息，确定目标切片位置处的切片数据，根据目标切片位置处的切片数据显示人体部位的三维切片模型，能够在三维切片模型中同时显示用户在三个维度上分别指定的三个目标切片位置处的切片图，这样用户可以更加便捷直观地查看不同目标切片位置处的切片图。
如上所述，用户可以利用位置调节控件分别指定不同维度上的不同目标切片位置，从而便于用户查看不同维度下不同目标切片位置处的切片图，在一种可能的实现方式中，根据在三个维度上分别指定的目标切片位置以及切片位置信息，确定目标切片位置处的切片数据，包括：响应于接收到针对目标维度的切片位置调节指令，确定切片位置调节指令所指示的目标维度下的目标切片位置处的切片数据。
其中，目标维度可以理解为用户所调节的目标切片位置所在的维度，目标维度可以 是三个维度中的任一维度，例如，用户利用上述位置调节控件，调节了X轴维度的目标切片位置，则X轴维度可以是目标维度，移动上述位置调节控件中X轴维度对应的“空心圆”的操作，可以理解为发出针对X轴维度上的切片位置调节指令，“空心圆”在线段上的位置对应于切片位置调节指令在X轴维度下所指示的目标切片位置。
其中，切片位置调节指令可以指示目标维度下的目标切片位置，也即得到目标维度下指定的目标切片位置，根据切片位置调节指令所指示的目标维度下的目标切片位置以及上述切片位置信息，可以确定出切片位置调节指令所指示的目标维度下的目标切片位置处的切片数据。
应理解的是，上述利用位置调节控件发出切片位置调节指令的方式是本公开实施例提供的一种实现方式，实际上，本领域技术人员可以设计并实现各种切片位置调节指令的实现方式，例如，还可以通过直接设置坐标位置等方式，对此本公开实施例不作限制。
在确定出切片位置调节指令所指示的目标维度下的目标切片位置处的切片数据后，在一种可能的实现方式中，根据目标切片位置处的切片数据，显示人体部位的三维切片模型，包括：根据切片位置调节指令所指示的目标维度下的目标切片位置处的切片数据，渲染人体部位在目标维度下的目标切片位置处的切片图。通过该方式，能够便捷地显示不同维度下不同目标切片位置处的切片图。
如上所述，本领域技术人员可以采用本领域已知的渲染技术，实现根据切片数据渲染出切片图；目标维度可以是三个维度中的任一维度，应理解的是，当首次在显示界面中显示三维切片模型时，可以根据三个维度上预设的默认切片位置渲染出三个维度的切片图，当用户调节目标维度上的目标切片位置时，可以在三维切片模型中重新渲染该目标维度上的切片图，其它维度上的切片图无需重新渲染。
图5示出根据本公开实施例的一种三维切片模型的示意图，如图5和图4中分别显示三个维度上不同目标切片位置处的切片图，应理解的是，可以是由图5调节至图4，也可以是由图4调节至图5，对此本公开实施例不作限制。
在本公开实施例中，用户可以通过调节目标切片位置，在三维切片模型中显示三个维度上不同目标切片位置处的切片图，使用户更便捷地同时查看不同维度的切片图。
考虑到，通过三维切片模型的方式显示三个维度的切片图，仍可能不够直观地体现出各个维度的切片图相对于人体部位的相对位置。在一种可能的实现方式中，三维扫描数据中还包括人体部位内的至少一个器官的器官轮廓信息与器官位置信息，所述方法还包括：
根据至少一个器官的器官轮廓信息与器官位置信息，在三维切片模型中渲染至少一个器官对应的三维图块；其中，各个三维图块具有与各个器官相似的外形轮廓，各个三维图块在三维切片模型中的显示位置对应于各个器官在人体部位内的实际位置。通过该方式，可以便于用户直观地查看到不同目标切片位置处的切片图相对于人体部位的相对位置，也便于用户理解不同目标切片位置处的切片图所展示的切片内容。
其中，器官轮廓信息可以表征人体部位内器官的外形轮廓，器官位置信息可以表征器官在人体部位内实际位置。应理解的是，用户可以预先设置要在三维切片模型中显示三维图块的器官类型(例如人体腹部内的肝脏、胰腺等)，器官轮廓信息与器官位置信息可以分别是根据用户设置的器官类型从三维扫描数据中提取的信息，对此本公开实施例不作限制。
应理解的是，在已知至少一个器官的器官轮廓信息与器官位置信息后，可以采用本领域已知的渲染技术，在三维切片模型中渲染至少一个器官对应的三维图块，三维图块在三维切片模型中相对于切片图来说是固定的，三维切片模型中可以显示不同目标切片位置的切片图，这样可以便于用户直观地查看到不同目标切片位置处的切片图相对于人体部位内器官的相对位置。
考虑到，用户还可能存在隐藏某些已显示的三维图块，和/或，显示某些已隐藏的三维图块的需求，在一种可能的实现方式中，所述方法还包括：响应于接收到针对已显示的三维图块的隐藏指令，将三维切片模型中隐藏指令所指示的三维图块进行隐藏；和/或，响应于接收到针对已隐藏的三维图块的显示指令，在三维切片模型中渲染显示指令所指示的三维图块。通过该方式，可以便于用户随机显示或隐藏器官的三维图块。
其中，隐藏指令可以指示所要隐藏的三维图块，当接收到该隐藏指令后可以对该隐藏指令所指示的三维图块进行隐藏，显示指令可以指示所要显示的三维图块，当接收到该显示指令后可以对该显示指令所指示的三维图块进行重新显示。
应理解的是，本领域技术人员可以根据实际需求设计并开发隐藏指令与显示指令的触发方式，例如，可以通过在显示界面中提供隐藏按钮和/或显示按钮，来便于用户利用隐藏按钮和/或显示按钮发出隐藏指令和/或显示指令，对此本公开实施例不作限制。
在一种可能的实现方式中，为了便于用于区分不同器官的三维图块，不同器官的三维图块可以采用不同颜色和/或不同透明度，也即，人体部位内不同器官对应的三维图块具有不同的显示效果，显示效果包括颜色、透明度中的至少一种，所述方法还包括：
响应于接收到针对三维图块的颜色调节指令，将颜色调节指令指示的三维图块的颜色，变换为颜色调节指令所指示的目标颜色；和/或，响应于接收到针对三维图块的透明度调节指令，将透明度调节指令指示的三维图块的透明度，变换为透明度调节指令所指示的目标透明度。通过该方式，可以便于用户自定义调节三维图块的显示效果。
应理解的是，本领域技术人员可以根据实际需求设计并开发颜色调节指令与透明度调节指令的触发方式，其中，例如可以在用户选中任一三维图块后提供输入框控件，以接收用户通过输入框控件所输入目标颜色的色值、目标透明度的数值等方式，对此本公开实施例不作限制。
考虑到，三维切片模型可以同时显示三个维度上的切片图，但用户可能存在只想看某个维度上的切片图的需求。在一种可能的实现方式中，三维切片模型具有三维视角、横切视角、纵切视角以及竖切视角中的至少一种视角模式，其中，三维视角用于同时展 示三个维度的切片图，横切视角用于展示X轴维度上的横切片图，纵切视角用于展示Y轴维度上的纵切片图，竖切视角用于展示Z轴维度上的竖切片图。
其中，三维切片模型当前显示为任一种视角模式，在一种可能的实现方式中，所述方法还包括：响应于接收到针对三维切片模型的视角切换指令，控制三维切片模型变换为视角切换指令所指示的目标视角模式。通过该方式，可以便于用户查看不同视角模式下的切片图。
其中，目标视角模式可以理解为视角切换指令所指示的、与当前显示的视角模式不同的视角模式。应理解的是，本领域技术人员可以根据实际需求设计并开发视角切换指令的触发方式，例如，可以通过在显示界面中提供视角切换按钮，来便于用户通过视角切换按钮发出视角切换指令，对此本公开实施例不作限制。
图6示出根据本公开实施例的一种三维切片模型的示意图，如图6所示的可以是一种竖切视角下的三维切片模型，该竖切视角下可以显示Z轴维度上的竖切片图。应理解的是，图6示出的三维切片模型还可以是横切视角或纵切视角，具体可以依据三维切片模型对应的三维坐标系中三个坐标轴的指向确定，对此本公开实施例不作限制。
其中，可以预设各个视角模型对应有默认位姿，当三维切片模型由当前视角模式切换至目标视角模式时，将三维切片模型的当前位姿调整为目标视角模式对应的默认位姿，从而实现控制三维切片模型变换为视角切换指令所指示的目标视角模式。
考虑到，除了上述四种视角模式的默认位姿，用户还可能存在查看自定义位姿下三维切片模型的需求，在一种可能的实现方式中，所述方法还包括：响应于接收到三维切片模型的位姿调节指令，将三维切片模型变换为位姿调节指令指示的目标位姿。通过该方式，可以便于用户将三维切片模型调节为自定义的目标位姿，便于用户查看不同位姿下的三维切片模型。
考虑到用户还可能存在调节切片图中不同切片组织的明暗对比效果，以突出显示某些切片组织的需求，在一种可能的实现方式中，所述方法还包括：响应于接收到针对三维切片模型中的切片图的明暗调节指令，根据明暗调节指令所指示的亮度与对比度中的至少一种，调节切片图中不同切片组织的明暗对比效果。通过该方式，可以便于用户自定义调节切片图中不同切片组织的明暗对比效果。
其中，根据明暗调节指令所指示的亮度与对比度中的至少一种，调节切片图中不同切片组织的明暗对比效果，可以理解为，根据明暗调节指令所指示的亮度与对比度中的至少一种，重新渲染三维切片模型内的各个切片图，使重新渲染的各个切片图中不同切片组织的明暗对比效果与明暗调节指令所指示的亮度和/或对比度相匹配。
应理解的是，本领域技术人员可以根据实际需求设计并开发明暗调节指令的触发方式，例如，可以参照上述位置调节控件的方式在显示界面中提供明暗调节控件，来便于用户通过明暗调节控件发出明暗调节指令，对此本公开实施例不作限制。
图7示出根据本公开实施例的一种三维切片模型的示意图，图7中的三维切片模型可 以是一种横切视角下的三维切片模型，图7中切片图与上述图4-6中切片图的明暗对比效果不同，图7示出的切片图中切片组织的亮度与对比度更高。
图8示出根据本公开实施例的一种控制面板的示意图，如图8所示的控制面板中提供了上述实现各种指令的相关控件，以便于用户利用控制面板对三维切片模型发出上述各种指令，其中，用户可以在“视角模式”处点击不同视角模式对应的按钮来切换视角模型，可以采用高亮、加粗、变色等方式指示选中的视角模式；可以在“图块模式”处通过设置“显示全部”按钮来显示全部三维图块，还可以设置“隐藏全部”按钮来隐藏全部三维图块，还可以设置三维图块是“三维模式”还是“切片模式”，“三维模式”可以理解为显示器官的完整三维图块，“切片模式”可以理解为显示目标切片位置处部分三维图块，部分三维图块可以具有预设厚度；可以在“X轴维度”、“Y轴维度”及“Z轴维度”处通过移动处“空心圆”在线段上的位置来调节目标切片位置；可以在“明暗对比”处通过调节线段两端的“空心圆”来调节亮度与对比度，其中两端的两个“空心圆”可以分别代表亮度与对比度；可以在“图块列表”处查看不同器官对应的三维图块的名称、颜色，还可以通过“隐藏”按钮来隐藏某个三维图块，还可以通过点击任一三维图块前的“+”展开按钮，展开设置颜色与透明度的输入框控件，用户可以在输入框中输入目标颜色的色值“FF0000”以及透明度“1.0”并点击“更新”按钮后来调节三维图块2的颜色与透明度中的至少一种，应理解的是，当点击“+”展开按钮展开输入框后，该“+”展开按钮可以变为“-”收起按钮，用户点击“-”收起按钮后可以收起上述输入框控件。
应理解的是，上述图8示出的控制面板本公开实施例提供的一种实现方式，本领域技术人员可以根据实际需求自定义设计控制面板以及控制面板中包含的功能控件等，例如，还可以设计修改三维图块名称的控件，对此本公开实施例不作限制。
考虑到，相关技术中的三维数据可视化方式，通常是把三维数据下载到本地，利用本地安装的三维软件加载三维数据，这种方式不便于查看三维切片模型，在打开三维切片模型时流程较为复杂，资源占用也较大。本公开实施例提供一种通过前端浏览器查看三维切片模型的实现方式，也即可以从后端服务器加载三维扫描数据，通过前端浏览器渲染三维切片模型，这样可以通过浏览器在线查看三维切片模型，无需本地安装三维软件，提高了查看三维切片模型的便捷性。
在一种可能的实现方式中，所述三维数据显示方法应用于前端浏览器，在步骤S11中，获取人体部位的三维扫描数据，包括：
获取后端服务器发送的具有原始数据格式的原始三维扫描数据；将原始三维扫描数据转换为具有预设数据格式的三维扫描数据；从具有预设数据格式的三维扫描数据中提取以下至少一种信息：人体部位在三个维度的切片数据、三个维度的切片数据的切片位置信息、人体部位内的至少一个器官的器官轮廓信息与器官位置信息。
在一种可能的实现方式中，原始数据格式例如可以采用Protobuf(一种数据描述语言，能够将结构化数据序列化)格式；其中，用户可以利用Protobuf技术自定义构造数据格式， 利用Protobuf技术构造的数据格式可以称为Protobuf格式，以便于实现前端浏览器与后端数据库之间的数据交互。
可知晓的是，利用Protobuf自定义构造数据格式时，通常生成Protobuf的定义文件proto文件，该proto文件中包含前后端进行数据交互时所约定的交互数据以及交互数据的解析方式等，一般前端浏览器可以预先获取到Protobuf的定义文件proto文件，其中，前端浏览器接收到.proto文件后，例如可以利用本地开源库grpc-tools和@grpc/grpc-js将.proto文件转换为特定的数据访问类文件(例如.js文件)，将数据访问类文件添加进去本地程序中，这样利用数据访问类文件中方法解析Protobuf格式的交互数据(如上述具有原始数据格式的原始三维扫描数据)，例如，利用数据访问类文件中的反序列化二进制方法，将原始三维扫描数据反序列解析为具有预设数据格式的三维扫描数据，再利用数据访问类文件中的对象数据获取方法，从具有上述三维扫描数据中提取以上至少一种信息等。
如上所述，该预设数据格式可以是浏览器在渲染切片图时所能识别的数据格式，预设数据格式例如可以是Vis3D格式，对此本公开实施例不作限制，也即从三维扫描数据中提取的切片数据具有上述Vis3D格式，便于根据切片数据渲染出切片图。
如上所述，三维扫描数据可以是CT设备扫描人体部位所得到的数据，为了便于通过浏览器在线查看人体部位的三维切片模型，CT设备可以将扫描得到的三维扫描数据上传至后端服务器，这样可以便于通过前端浏览器从后端服务器中在线获取三维扫描数据，并基于三维扫描数据显示三维切片模型。
在本公开实施例中，实现了三维扫描数据的在线可视化，可以在浏览器中直接查看Vis3D格式文件；支持向后端服务器上传三维扫描数据，上传后可通过浏览器中直接在线查看三维切片模型，提高了用户查看三维切片模型的便捷性。
根据本公开的实施例，能够实现三维扫描数据的在线查看，相对于相关技术中将三维扫描数据下载至本地并使用三维软件查看来说，降低了查看三维扫描数据所需的环境配置成本，且可在一个显示界面上同时渲染至少两个三维切片模型供用户对比查看。
根据本公开的实施例，还可以应用于网络模型训练系统，能够在网络模型训练期间查看网络模型的训练效果，网络模型可以用于生成三维切片模型，便于提升网络模型的开发效率。
可以理解，本公开提及的上述各个方法实施例，在不违背原理逻辑的情况下，均可以彼此相互结合形成结合后的实施例，限于篇幅，本公开不再赘述。本领域技术人员可以理解，在具体实施方式的上述方法中，各步骤的具体执行顺序应当以其功能和可能的内在逻辑确定。
此外，本公开还提供了三维数据显示装置、电子设备、计算机可读存储介质、程序，上述均可用来实现本公开提供的任一种三维数据显示方法，相应技术方案和描述和参见方法部分的相应记载，不再赘述。
