图1示出本公开实施例提供的一种目标显示方法的流程示意图，如图1所示，该目标显示方法由电子设备执行，该方法包括：
在步骤S11中，响应于第一图像中被触发的第一目标，确定第一目标与第二目标的位置关系，第一图像中包括可触发的多个第一目标及与多个第一目标连接的第二目标。
在步骤S12中，根据位置关系，确定与第一目标对应的绘制参数。
在步骤S13中，根据绘制参数，生成并显示第二图像；其中，第一目标处于第二图像的预设区域且第一目标位于第二目标前面。
在本公开实施例中，目标显示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、用户终端、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，目标显示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，可通过服务器执行所述方法。
在本公开实施例中，第一图像可包括对象(例如人或动物)的生理区域(例如脑部区域、胸腹区域等)的体绘制图像，即VR图像。例如，第一图像可以为心脏冠状动脉的体绘制图像，可根据心脏冠状动脉CT图像，通过体绘制技术生成。应当理解，本公开实施例对第一图像显示的具体生理区域不作限制。
在本公开实施例中，可在显示界面中显示第一图像。其中，显示界面可包括显示窗口或视窗，例如，显示界面可以是图像分析或图像处理应用程序的图像显示窗口。
在本公开实施例中，可在步骤S11中，响应于第一图像中被触发的第一目标，确定第一目标与第二目标的位置关系，第一图像中包括可触发的多个第一目标及与多个第一目标连接的第二目标。
其中，第一图像对应的生理区域不同，第一目标及第二目标可能不同。例如，在第一图像为脑部的VR图像时，第一目标可包括脑血管，第二目标可包括与脑血管连接的大脑和/或小脑；在第一图像为心脏冠状静脉的VR图像时，第一目标可包括冠状静脉，第二目标可包括与冠状静脉连接的心脏；在第一图像为心脏冠状动脉的VR图像时，第一目标可包括冠状动脉，第二目标可包括与冠状动脉连接的心脏。
需要说明的是，本领域技术人员可根据实际情况确定第一目标及第二目标，本公开实施例对此不作限制。
在本公开实施例中，第一目标的触发方式可有多种。例如，可在多个第一目标的列表中，通过鼠标、键盘等操作，选中第一目标；也可在第一图像上，通过鼠标点击或手指触碰，选中第一目标；还可通过其他方式触发第一目标。本公开实施例对第一目标的触发方式不作限制。
在第一图像中的任一第一目标被触发时，可响应于被触发的第一目标，通过关键点位置分析、向量投影等方式，确定第一目标与第二目标的位置关系。其中，位置关系可包括第一目标位于第二目标前面、第一目标位于第二目标后面。这里的前面与后面，是相对于查看第一图像的用户而言的，靠近用户的方向为前面，远离用户或与前面相反的方向为后面。
在本公开实施例中，确定第一目标与第二目标的位置关系后，可在步骤S12中，根据位置关系，确定与第一目标对应的绘制参数。绘制图像的方式不同，绘制参数也可能不同。例如，通过三维坐标系绘制图像时，绘制参数可包括原点位置、各个坐标轴的方向等；根据第一目标的最佳视角(即用户最佳观看角度)绘制图像时，绘制参数可包括原点位置、第一目标竖直向上的方向、第一目标水平向前的方向等。
需要说明的是，本领域技术人员可根据实际情况确定绘制参数的具体内容，本公开实施例对此不作限制。
在本公开实施例中，确定绘制参数后，可在步骤S13中，根据与第一目标对应的绘制参数，生成并显示第二图像；其中，第一目标处于第二图像的预设区域且第一目标位于第二目标前面。
其中，预设区域可以为预先设置的第二图像中便于用户查看的区域，例如，预设区域可以为第二图像的中心区域，即包括第二图像的中心位置的区域。本公开实施例对预设区域的具体位置及大小不作限制。
根据本公开的实施例，能够在第一图像中的第一目标被触发时，响应于被触发的第一目标，确定 第一目标与第二目标的位置关系，根据位置关系，确定与第一目标对应的绘制参数，并根据绘制参数，生成并显示第二图像，以使第一目标处于第二图像的预设区域且第一目标位于第二目标前面，从而可以在第一图像中的第一目标被触发时，通过图像重绘，得到第二图像，第二图像中的第一目标处于预设区域且第一目标位于第二目标前面，不仅可减少图像的旋转及调整次数，还可减少第二目标对被触发的第一目标的遮挡，进而提高用户使用的便利性。
图2示出可以应用本公开实施例的目标显示方法的一种系统架构示意图；如图2所示，该系统架构中包括：位置关系确定终端201、网络202和目标显示终端203。为实现支撑一个示例性应用，位置关系确定终端201和目标显示终端203通过网络202建立通信连接，位置关系确定终端201通过网络202向目标显示终端203上报位置关系，目标显示终端203响应于位置关系，并根据位置关系，确定与第一目标对应的绘制参数；根据绘制参数，生成并显示第二图像；其中，第一目标处于第二图像的预设区域且第一目标位于第二目标前面。最后，目标显示终端203将第二图像上传至网络202，并通过网络202发送给位置关系确定终端201。
作为示例，位置关系确定终端201可以包括视频采集设备或触摸设备，目标显示终端203可以包括具有视觉信息处理能力的视觉处理设备或远程服务器。网络202可以采用有线或无线连接方式。其中，当目标显示终端203为视觉处理设备时，位置关系确定终端201可以通过有线连接的方式与视觉处理设备通信连接，例如通过总线进行数据通信；当目标显示终端203为远程服务器时，位置关系确定终端201可以通过无线网络与远程服务器进行数据交互。
或者，在一些场景中，位置关系确定终端201可以是带有触摸功能模组的视觉处理设备，具体实现为带有触摸功能的主机。这时，本公开实施例的目标显示方法可以由位置关系确定终端201执行，上述系统架构可以不包含网络202和目标显示终端203。
在本公开实施例中，步骤S11可包括：响应于被触发的第一目标，分别确定第一目标的中心点、起点及终点，起点包括第一目标与第二目标连接的一端的端点，终点包括第一目标的另一端的端点，第一目标的中心点处于第一目标的外接空间的中心区域；根据第二目标的中心点、第一目标的中心点、起点及终点，确定第一目标与第二目标的位置关系，第二目标的中心点处于第二目标的外接空间的中心区域。
其中，第一目标的外接空间，可以是与第一目标存在连接点且将第一目标包围在其中的三维空间。外接空间的形状可以为球体、正方体、长方体等。外接空间的中心区域可以是以外接空间的几何中心点为中心的、一定大小的区域。本公开实施例对接空间及其中心区域的具体形状及大小均不作限制。
在本公开实施例中，确定第一目标的中心点时，可首先确定第一目标的外接空间的中心区域，然后将中心区域的中心点，或中心区域中的任一点，确定为第一目标的中心点。
第二目标的中心点的确定方式，与上述第一目标的中心点的确定方式类似，此处不再赘述。
在本公开实施例中，可将第一目标的最小外接长方体的中心点，确定为第一目标的中心点，将第二目标的最小外接长方体的中心点，确定为第二目标的中心点。
在本公开实施例中，确定第一目标的起点或终点时，可将第一目标与第二目标连接的一端的端点，确定为第一目标的起点；将第一目标的另一端的端点，确定为第一目标的终点。
在本公开实施例中，确定第一目标的起点及终点时，还可首先提取第一目标的中心线，然后将中心线与第二目标连接的一端的端点，确定为第一目标的起点，将第一目标的中心线的另一端的端点，确定为第一目标的终点。
举例来说，第一目标为冠状动脉时，与多个第一目标连接的第二目标为心脏。由于冠状动脉的走势通常是由心脏向外凸起的，在确定冠状动脉(即第一目标)的起点及终点时，可首先提取冠状动脉的中心线，然后将中心线与心脏(即第二目标)连接的一端的端点，确定为冠状动脉的起点，将中心线的另一端的端点，确定为冠状动脉的终点。
在本公开实施例中，可根据第二目标的中心点、第一目标的中心点、起点及终点，通过确定方向向量、向量叉乘运算、向量投影等操作，确定第一目标与第二目标的位置关系。
本公开的实施例，可响应于被触发的第一目标，分别确定第一目标的中心点、起点及终点，并根 据第二目标的中心点、第一目标的中心点、起点及终点，确定第一目标与第二目标的位置关系，从而可根据第一目标的走势、第一目标及第二目标的中心点，确定第一目标与第二目标的位置关系，可提高位置关系的准确性。
在本公开实施例中，根据第二目标的中心点、第一目标的中心点、起点及终点，确定第一目标与第二目标的位置关系，包括：根据第一目标的起点及终点，确定第一目标的第一向量；根据第一目标的中心点及第一向量，确定第一目标的第二向量；根据第二目标的中心点及第一目标的中心点，确定第三向量；根据第一向量、第二向量及第三向量，确定第一目标与第二目标的位置关系。
在本公开实施例中，可根据第一目标的起点及终点，确定第一目标的第一向量。例如，可将从第一目标的起点指向其终点的向量，即将第一目标首尾连接的向量，确定为第一目标的第一向量。
在本公开实施例中，可根据第一目标的中心点及第一向量，确定第一目标的第二向量。根据第一目标的中心点及第一向量，可确定出一个平面；可在右手坐标系中，将该平面的法向量，确定为第一目标的第二向量。即第二向量垂直于由第一目标的中心点及第一向量确定的平面。
在本公开实施例中，可根据第二目标的中心点及第一目标的中心点，确定第三向量。例如，第一目标的中心点为冠状动脉的中心点，第二目标的中心点为心脏的中心点，可将从冠状动脉的中心点指向心脏的中心点的向量，确定为第三向量。

举例来说，第一目标为冠状动脉，第二目标为心脏时，第一显示模式可用于显示多条冠状动脉及心脏，在第一显示模式下，第二图像包括多个冠状动脉及心脏，可认为第一显示模式为全心脏显示模式；第二显示模式可用于显示多条冠状动脉，在第二显示模式下，第二图像包括多个冠状动脉，但心脏被隐藏不显示，可认为第二显示模式为冠脉显示模式。
本公开的实施例，可根据绘制参数，生成第二图像，还可根据被选中的显示模式，显示第二图像，从而可使得第二图像在不同的显示模式下进行显示。
在本公开实施例中，该目标显示方法还可包括：对待处理图像进行目标识别，确定待处理图像中的多个第一目标及第二目标的位置；根据多个第一目标及第二目标的位置，生成第一图像。
其中，待处理图像可包括心脏冠状动脉CT图像、脑部CT图像等，本公开实施例对待处理图像的具体类型不作限制。
在本公开实施例中，可通过深度学习等方式，对待处理图像进行目标识别，确定待处理图像中的多个第一目标及第二目标的位置，并根据多个第一目标及第二目标的位置，生成第一图像。
举例来说，待处理图像为心脏冠状动脉CT图像时，可通过用于目标识别的神经网络，对待处理图像进行目标识别，确定出待处理图像中的多条冠状动脉(即第一目标)及心脏(即第二目标)的位置；然后根据多条冠状动脉及心脏的位置，通过体绘制技术，生成第一图像，该第一图像可包括多条冠状动脉及心脏。
本公开的实施例，通过对待处理图像进行目标识别，确定待处理图像中的多个第一目标及第二目标的位置，并根据多个第一目标及第二目标的位置，生成第一图像，从而可提高第一图像的准确性。
在本公开实施例中，根据多个第一目标及第二目标的位置，生成第一图像，可包括：根据多个第一目标及第二目标的位置，对待处理图像进行分割，得到待处理图像的分割图像；根据分割图像，生成第一图像。
也就是说，在生成第一图像时，可根据多个第一目标及第二目标的位置，通过图像分割算法，对待处理图像进行分割，得到待处理图像的分割图像，然后可根据分割图像，通过体绘制技术，生成第一图像。
本公开的实施例，可通过图像分割，得到处理图像的分割图像，并根据分割图像，生成第一图像，可提高第一图像的准确性。
图3示出本公开实施例提供的一种目标显示方法的处理过程的示意图。如图3所示，假设待处理图像为心脏冠状动脉CT图像，第一目标为冠状动脉，第二目标为心脏。可首先在步骤S301中，对待处理图像进行目标识别，确定待处理图像中的多个第一目标及第二目标的位置；在步骤S302中，根据多个第一目标及第二目标的位置，生成第一图像；在步骤S303中，在图像分析软件的显示界面中显示第一图像，第一图像中包括可触发的多个第一目标及与多个第一目标连接的第二目标。
在第一图像中的任一第一目标被触发时，可在步骤S304中，响应于被触发的第一目标，分别确定第一目标的中心点、起点及终点；在步骤S305中，将从第一目标的起点指向第一目标的终点的向量，确定为第一目标的第一向量(表示up-direction)；在步骤S306中，将从第一目标的中心点指向第一目标的起点或终点的向量，确定第六向量，并对第一向量及第六向量进行叉乘，得到第一目标的第二向量(表示right-direction)；在步骤S307中，将从第一目标的中心点指向第二目标的中心点的向量，确定为第三向量，并对第一向量及第二向量进行叉乘，得到第四向量；在步骤S308中，确定第四向量在第三向量上的投影值；在步骤S309中，判断投影值是否小于零；在投影值小于零的情况下，可认为第一目标(冠状动脉)位于第二目标(心脏)后面，可在步骤S310中，将第四向量的反向量，确定为第五向量(表示view-direction)；在投影值大于或等于零的情况下，可认为第一目标(冠状动脉)位于第二目标(心脏)前面，可在步骤S311中，将第四向量直接确定为第五向量(表示view-direction)。
可在步骤3212中，将第二目标的中心点以及确定出的第一向量、第五向量，确定为与第一目标对应的绘制参数；在步骤S313中，根据与第一目标对应的绘制参数，生成第二图像，其中，第一目标(冠状动脉)处于第二图像的中心位置，且第一目标(冠状动脉)位于第二目标(心脏)前面，并在步骤 S314中，根据被选中的显示模式，显示第二图像。
根据本公开的实施例，上述目标显示方法可应用于包括体绘制图像显示的各种应用软件，例如图像分析软件、影像分析软件、图像处理软件等。应用软件可根据待处理图像，生成并在其显示界面中显示第一图像，其中，第一图像中包括可触发的多个第一目标及与多个第一目标连接的第二目标；应用软件还可响应于被触发的第一目标，确定第一目标与第二目标的位置关系，根据位置关系，确定与第一目标对应的绘制参数，并根据该绘制参数，生成并显示第二图像，以使第一目标处于第二图像的预设区域且第一目标位于第二目标前面，从而可以在第一图像中的第一目标被触发时，通过图像重绘，得到第二图像，第二图像中的第一目标处于预设区域且第一目标位于第二目标前面，不仅可使得第一目标处于预设区域，减少图像的旋转及调整次数，而且可以使得第一目标位于第二目标前面，减少第二目标对被触发的第一目标的遮挡，进而提高用户使用的便利性。
例如，心脏冠状动脉CT图像可用于查看冠状动脉狭窄程度和进行斑块分析。在通过影像分析软件对心脏冠状动脉CT图像进行分析或查看时，用户可将待分析或待查看的心脏冠状动脉CT图像加载到影像分析软件中，影像分析软件可根据加载的心脏冠状动脉CT图像，生成并在其显示界面中显示冠状动脉体绘制图像，影像分析软件还可显示冠状动脉体绘制图像中所有可识别的冠状动脉的列表(即冠状动脉列表)。
用户可根据需要，通过鼠标点击等方式，选中冠状动脉列表中的任意一条冠状动脉进行分析或查看，此时，影像分析软件可响应于被触发(即被选中)的冠状动脉，根据被触发的冠状动脉的走势，以及被触发的冠状动脉与心脏的位置关系，确定与被触发的冠状动脉对应的绘制参数，然后根据该绘制参数，重新绘制图像，并在显示界面中进行显示，从而可在全心脏显示模式或冠脉显示模式下，使得被触发的冠状动脉位于图像的中心位置且冠状动脉位于心脏前面，不仅可减少心脏对被选中的冠状动脉的遮挡，还可减少图像的旋转或调整次数，提高了用户使用的便利性。
