相关申请的交叉引用
本申请要求在2020年03月06日提交中国专利局、申请号为202010153540.9、申请名称为“一种非视距物体的成像方法和电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种非视距物体的成像方法和电子设备。
背景技术
电磁波因可以穿透部分物体表面，常被用于探测物体的内部结构或者探测非视距(not line of sight，NLOS)物体，并对物体成像，可广泛应用在医学、安检等技术领域。电磁波的成像原理是通过主动或者被动检测拟成像目标，例如重构物体的形状、特征，形成图像。
天线阵元越多，可实现的电磁波的波束越窄，可控制的波束扫描范围越宽，所以为了满足波束扫描范围宽的需求，目前电磁成像装置(例如计算机断层(computed tomography，CT)扫描仪、安检设备等)的体积较大，无法满足多种应用场景。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，并不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
电磁波成像是一种以电磁波作为信息载体的成像手段，电磁波频段较高，所以可以穿透部分拟成像物体，即实现对拟成像物体的内部结构的透视。也因此电磁波成像常被用于探测物体的内部结构或者探测非视距物体，并对物体成像，可广泛应用在医学、安检等技 术领域。应理解，这里非视距物体指的是肉眼看不到的物体或者可见光不可见的物体，例如被障碍物遮挡的物体，例如隐藏在墙内的电线等。电磁波成像主要是通过主动或者被动检测拟成像物体及周围散射场的信号，重构拟成像物体的形状、特征或者介电常数分布，形成图像。电磁波成像主要有主动电磁成像和被动电磁成像这两种电磁成像方式。
1)主动电磁成像，指成像装置内的发射机主动向拟成像物体发送电磁波，拟成像物体对接收的电磁波进行反射，反射后的电磁波被成像装置内的接收机接收。在本文中，发射后的电磁波也称为回波信号，成像装置对接收的回波信号进行处理，例如从回波信号中提取用于表征拟成像物体的目标特征，例如表征拟成像物体的轮廓的特征等，根据该目标特征对拟成像物体进行成像。
2)被动电磁成像，指成像装置通过例如接收天线获取拟成像物体所在空间内的电磁辐射信息，利用不同物体的电磁辐射强度的差异进行成像。典型的被动电磁成像，例如为红外波段的热成像。具体的，例如可以收集来自拟成像物体的辐射能量，将收集的辐射能量转化为电信号，并对电信号进行处理，例如对电信号进行显影、定影、校正等处理，最后将处理的信号输出，例如输出给扫描晒像仪、电视显像管、阴极射线管等，实现拟成像物体的成像。
在电磁波成像中，天线孔径的大小与成像分辨率成正比，即满足：ρ∝D，其中，ρ为成像分辨率，D为天线孔径。通常，天线以阵列的形式存在，即多个天线以阵列的方式形成天线阵列，每个天线也可看作是一个天线阵元。以线性天线阵列为例，设电磁波波长为λ，该天线阵列包括N个天线，且这N个天线每个天线的中心按照λ/2等间隔排列，那么天线孔径D等于N*λ/2。为了得到较高的成像分辨率，天线阵元越多越好。且天线阵元越多，可实现的电磁波的波束越窄，可控制的波束扫描范围越宽，所以为了满足波束扫描范围宽的需求，目前电磁成像装置(例如CT扫描仪、安检设备等)的体积较大，无法满足各种应该场景的使用。相对而言，手持设备例如手机，受空间限制，可安装的天线阵元的数量较少，因此电磁成像的成像分辨率也较低，即成像性能较差。
鉴于此，本申请实施例一种非视距物体的成像方法和电子设备，该电子设备包括能够采集电磁信号的第一组件，也可以理解为第一组件能够发射以及接收电磁信号。在对非视距物体成像时，可移动电子设备。由于电子设备移动，可实现较宽的波束扫描范围，从而可以提升电磁成像的成像分辨率，因此可通过体积较小的便携设备实现对多种应该场景下的非视距物体的成像。另外，该方法可应用于不限于手机等便携设备，例如可应用于车辆等移动设备，用于自动驾驶中的目标探测和跟踪。
本申请实施例可以应用在任何具备电磁成像功能的电子设备中，用以执行本申请实施例提供的非视距物体的成像方法。下面介绍本申请实施例提供的一种可能的电子设备，以及使用该电子设备进行图像成像的实施例。

本申请实施例涉及的预览图像，是指电子设备的取景界面中显示的图像。比如，电子设备是手机100时，手机100启动相机应用，打开摄像头，显示取景界面，该取景界面中显示预览图像。继续以手机100为例，手机100启动视频通话功能时，打开摄像头，显示取景界面，该取景界面中显示预览图像。
本申请实施例以利用手机100的相机应用为例，但是不限于相机应用，例如可以是手机100上的其他应用，例如启动该应用，可默认对非视距物体进行成像。
示例1：手机100单视角拍摄图像。
请参见图2，为本申请实施例提供的一种应用场景的示例。如图2所示，拟成像物体(例如盒子)被遮挡物(墙体)遮挡，这种情况下，拟成像物体即盒子可以认为是非视距物体，墙体可以认为是视距物体。请参见图3，为本申请实施例提供的另一种应用场景的示例。如图3所示，拟成像物体(例如剪刀)被遮挡物(盒子)遮挡，这种情况下，拟成像物体即剪刀可以认为是非视距物体，盒子是视距物体。
下面以图3的场景为例，介绍手机100拍摄非视距物体的流程。请参见图4，为手机100拍摄该非视距物体的图像的流程示意图。应理解手机100包括至少一个运动传感器，例如陀螺仪传感器180B和/或加速度传感器180E，或者至少一个运动传感器可包括光学摄像头。该手机100还包括至少一个电磁传感器，例如可以是手机100上用于通信的天线，也可以是独立于手机100上用于通信的天线。如图4所述，该拍摄过程包括：
S401、检测到第一操作。
示例性的，手机100的显示屏194显示主界面，主界面中包括各个应用程序的图标(比如相机应用图标、微信应用图标等等)。用户通过设置于显示屏194上的触摸传感器180K检测用户在显示屏194上的第一操作，第一操作可以是点击主界面中的相机应用图标的操作。当然，第一操作还可以是其它操作，例如在锁屏界面上滑的操作，或者长按音量键的操作等，只要是能够启动相机的操作即可，本申请实施例不作限定。
S402、响应于所述第一操作，打开光学摄像头，进入第一成像模式，显示取景界面。
本申请实施例提供的手机100可以对可见物体例如人像进行拍照，又可以对非视距物体进行拍照。应理解，人像和非视距物体是相对而言的，也就是手机100支持至少两种成像模式。
示例性的，请参见图5，为相机显示界面的示意图。从图5可以看出，相机显示界面中包括多种成像模式的图标(比如人像图标、非视距物体图标等等)。“人像”成像模式也可以理解为光学成像模式，相对的，“非视距物体”成像模式也可以理解为电磁成像模式。应理解，在本申请实施例中，人像图标和非视距物体图标仅是作为区分光学成像和电磁成像的一种示意。由于电磁成像相对光学成像来说，更能够感知拟成像物体。从这个角度而言，可以认为光学成像对应“照片”成像模式(又称为照片模式)，电磁成像可对应“感知”成像模式(又称为感知模式)。为了便于描述，下文中，以光学成像对应照片模式，电磁成像对应感知模式为例。应理解，第一成像模式可以是照片模式，也可以是感知模式(图5以此为例)。
S403、检测到触发信号。
用户在显示屏194上的第二操作，该第二操作可以是点击相机显示界面中的非视距物体图标的操作，手机100通过设置于显示屏194上的触摸传感器180K检测到第二操作。当然，第二操作还可以是其它操作，例如在相机显示界面上滑的操作，或者长按音量键的操作等，只要是能够进入第一成像模式的操作即可，本申请实施例不作限定。
需要说明的是，本申请实施例以电子设备是手机100为例，如果电子设备是其他不具备显示屏的设备，那么用户也可以在该电子设备上进行操作，此时电子设备生成触发信号， 以触发该电子设备进入第一成像模式。应理解，用户在显示屏194上进行能够进入第一成像模式的操作，此时手机100生成触发信号，从这个角度而言，也可以认为，手机100通过设置于显示屏194上的触摸传感器180K检测到该触发信号。
又一示例性的，相机显示界面中包括成像模式选项控件，当手机100检测到针对该控件的操作时，显示包含多种成像模式的选择框，其中包括“照片”选项、“感知”选项等。当手机100检测到针对“照片”选项或“感知”选项的操作时，进入第一成像模式。为了便于描述，下文中，以第一成像模式是“感知”成像模式，即电磁成像模式为例。
前述仅是列举了两种用户手动设置手机100进入第一成像模式的方式，在实际应用中，还可以由其他的手动方式进入第一成像模式，例如相机显示界面中包括预览图像，该预览图像包括电磁图像，用户可以手动选择电磁图像，也就是针对该电磁图像进行操作。如果用户针对该电磁图像进行操作，可认为用户手动选择进入第一成像模式。本申请实施例不再一一列举。
应理解，如果用户针对预览图像进行操作，那么手机100需要开启光学摄像头。在一些实施例中，手机100响应于所述第一操作，启动相机应用，开启光学摄像头。而如果第一成像模式是“感知”模式，那么手机100还需要启动电磁传感器。在一些实施例中，手机100检测到第一操作，例如点击主界面中的相机应用图标的操作，启动光学摄像头，之后检测到第二操作，例如点击相机显示界面中的“感知”图标的操作，启动电磁传感器，否则不开启电磁传感器，以尽量节省手机100的能耗。当然在另一些实施例中，手机100检测到第一操作，例如点击主界面中的相机应用图标的操作，启动光学摄像头和电磁传感器。需要说明的是，如果电磁传感器与电子设备用于通信的天线复用，那么默认电磁传感器一直处于开启状态。
手机100进入第一成像模式之后，显示取景画面。可能存在拟成像物体不在取景画面内，所以用户可以调整手机100与拟成像物体的相对位置，使得拟成像物体位于取景画面内，以保证手机100可以采集到拟成像物体的图像。
之后，在需要对拟成像物体进行拍照时，用户可以触发手机100对拟成像物体进行拍照。示例性的，手机100可以通过设置于显示屏194上的触摸传感器180K检测用户在显示屏194上的第三操作，该第三操作可以是点击相机显示界面中的拍照图标的操作。当然，第三操作还可以是其它操作，例如在取景显示界面上滑的操作，或者长按音量键的操作等，只要是能够触发拍照的操作即可，本申请实施例不作限定。或者，手机100进入第一成像模式之后，如果检测到拟成像物体位于取景画面中，手机100可以自动触发对拟成像物体进行拍照。
之后手机100的电磁传感器可采集来自非视距物体的多个第一数据。应理解，如果手机100支持主动电磁成像，那么手机100通过天线发射电磁波，照射拟成像空间区域(应理解视距物体和非视距物体位于该空间区域内)，如图6所示。视距物体和非视距物体接收电磁波，将接收的电磁波反射给电磁传感器，即电磁传感器接收回波信号。之后，电磁传感器可以提取回波信号的辐射信息，进而根据该辐射信息进行非视距物体的成像。应理解，回波信号的辐射信息可以包括视距物体以及非视距物体的电磁辐射信息，通过该电磁辐射信息可以确定视距物体以及非视距物体在空间的分布，也就是视距物体以及非视距物体的各个位置点在空间上的分布。需要说明的是，第一数据可以是回波信号，也可以是回波信号的辐射信息，例如回波信号的能量。
如果手机100支持被动电磁成像，那么手机100通过天线获取拟成像空间内的辐射信息，利用不同物体(视距物体和非视距物体)的辐射强度的差异，实现进行成像。应理解，此时第一数据为指示辐射强度的数据。
本申请实施例旨在通过移动手机100，虚拟出较大的天线阵列。因此，触发对非视距物体进行成像之后，用户可移动手机100。应理解，手机100在移动，那么不同的位置处，电磁传感器采集的第一数据也有所不同，为了保证第一数据和手机的运动轨迹能够较好地匹配，手机100在电磁传感器采集第一数据之前，可在取景画面可显示辅助提示信息。该辅助提示信息可以用于指导用户如何移动电子设备，也就是移动电子设备需要遵循的规则，例如可以为沿手机100的长度方向或沿手机100的宽度方向移动手机100，这种情况下，辅助提示信息可以是沿某个方向的直线。又例如辅助提示信息可以是曲线，或者旋转角度，用户可以根据该辅助提示信息指示的轨迹移动手机100。
在可能的设计中，该辅助提示信息可包括手机100移动轨迹的图样。示例性的，请参见图7，为一种辅助提示信息的示例；另一示例性的，请参见图8，为另一种辅助提示信息的示例；再一示例性的，请参见图9，为另一种辅助提示信息的示例。应理解，图7-图9只是为了示意，本申请实施例不限制辅助提示信息包括的手机100移动轨迹的图样的具体形式。
应理解，辅助提示信息可包括多种手机100移动轨迹的图样，这样用户就可以根据实际要成像的非视距物体和/或视距物体来选择采用哪种图样，以尽量获得非视距物体的完整成像。
在一些实施例中，可在相机显示界面中包括“辅助提示信息”选项控件，当手机100检测到针对该控件的操作时，显示包含多种“辅助提示信息”的选择框，其中包括“扫描图样1”选项、“扫描图样2”选项等。当手机100检测到针对“扫描图样1”选项的操作时，在显示界面显示扫描图样1。
或者，相机显示界面可显示多种“辅助提示信息”的图标。例如，请参见图10，为显示界面的一种示意。相机显示界面可显示“扫描图样1”图标、“扫描图样2”图标、“扫描图样2”图标等。当手机100检测到针对“扫描图样1”选项的操作时，在显示界面显示扫描图样1。
应理解，在一些实施例中，手机100检测到触发拍照的操作，即前述的第三操作，默认在相机显示界面显示例如扫描图样1，可理解为第一扫描提示图样。之后检测到例如针对“扫描图样2”选项或“扫描图样2”图标的操作时，显示第二扫描提示图样，也就是扫描图样2。
在可能的设计中，辅助提示信息还可以包括其他提示信息，例如用于提示手机100的移动速度过快的信息，用于提示用户手机100方向偏离的信息等，以尽量保证非视距物体的成像性能。
示例性的，手机100在移动过程中，可以获取手机100的移动速度，应理解，该移动速度可以是瞬时速度，也可以是预设时长内的平均速度。当手机100确定所获取的移动速度大于预设阈值，那么手机100移动较快，此时可在显示界面显示第一提示信息，该第一提示信息用于用户采用比该移动速度小的速度移动手机100。如图10所示，第一提示信息可以是在显示界面显示的“请减速”，或者第一提示信息可以是扫描图样1中的“箭头”，且该“箭头”的颜色为预设颜色；或者第一提示信息也可以是扫描图样1，且扫描图样1的颜色为预设颜色；或者第一提示信息可以是扫描图样1中的“箭头”，且该“箭头”按照预设频 率闪烁，等等。第一提示信息也可以是上述几种提示信息的多种组合，本申请实施不作限制。
应理解，当手机100超出显示界面显示的扫描图样的扫描范围，可在显示界面显示第二提示信息，该第二提示信息可用于提示用户改变手机100的移动方向。如图10所示，第二提示信息可以是在显示界面显示的“请改变移动方向”，或者第二提示信息可以是扫描图样1中的“箭头”，且该“箭头”的颜色为预设颜色；或者第二提示信息也可以是扫描图样1，且扫描图样1的颜色为预设颜色；或者第二提示信息可以是扫描图样1中的“箭头”，且该“箭头”按照预设频率闪烁，等等。第二提示信息也可以是上述几种提示信息的多种组合，本申请实施不作限制。
应理解，当手机100在移动过程中发生抖动，例如手机100从横屏切换到竖屏，或者由竖屏切换到横屏，可在显示界面显示第三提示信息，该第三提示信息可用于提示用户向指定方向移动手机100。如图10所示，第三提示信息可以是在显示界面显示的“向上移动”；或者第三提示信息与第一提示信息或第二提示信息类似，第三提示信息也可以是扫描图样1中的“箭头”，且该“箭头”的颜色为预设颜色，这里不再赘述。
S404、响应于所述触发信号，获取电磁传感器采集的第一数据，以及获取至少一个运动传感器采集的第二数据。
应理解，第一数据是电磁传感器采集的电磁信号，如前述可以是回波信号，也可以是回波信号的辐射信息，例如回波信号的能量。至少一个运动传感器可包括姿态传感器、加速度传感器和陀螺仪，以及光学摄像头、激光雷达、毫米波雷达等的一种或多种组合。第二数据可以是用于表征手机100的位置的数据，例如可包括至少一个运动传感器采集的图像信息和/或电子设备的移动信息。例如至少一个运动传感器包括光学摄像头或激光雷达，那么第二数据包括至少一个运动传感器采集的图像信息；例如至少一个运动传感器包括姿态传感器、加速度传感器、陀螺仪等，那么第二数据包括至少一个运动传感器采集的手机100的移动信息。
应理解，手机100在移动过程中，电磁传感器持续采集来自非视距物体的第一数据，同理，至少一个运动传感器持续采集手机100的第二数据。在一段时间内，至少一个运动传感器采集的第二数据可包括M个第二采样数据。每个第二数据的采样时刻对应一个物理空间位置，因此手机100根据M个第二采样数据可以确定手机100的实际移动轨迹。
为了便于理解，请参见图11，为确定移动轨迹的示意图。应理解，手机100的移动轨迹可以是二维平面上的轨迹，也可以是三维空间上的轨迹。为方便显示，图11以二维平面示意，且以手机100的移动轨迹是曲线为例。图11中X和Y分别表示二维平面的两个轴，例如X表示水平轴，Y表示垂直轴。
假设手机100累计的移动时长为T秒，在T秒内，手机100中某个运动传感器采集的第二数据可表示为{S x，S y，S z}，其中，S x，S y，S z分别表示该传感器在X轴、Y轴和Z轴采集的信号，也可以理解为信号值。如果该运动传感器的采样率为K 1Hz，那么手机100在T秒内采集的第二数据的集合可表示为：
Figure PCTCN2021075658-appb-000003
其中，M＝K 1*T。
应理解，多个运动传感器在T秒内采集的第二数据的集合是多维的，将这多维的第二数据进行积分可恢复手机100的移动轨迹。以多个运动传感器包括加速度传感器和陀螺仪传感器为例，得到表征手机100的二维平面轨迹的第二数据的集合可表示为：
Figure PCTCN2021075658-appb-000004
其中，i行表示X轴，j列表示Y轴，P i,j表示空间上的一个物理位置。
手机100可在显示界面上显示手机100的运动轨迹，具体的，手机100可获取N个第二数据中的部分或全部第二数据，并分别计算提取的第二数据中任意相邻的两个第二数据在第一参考坐标系中的位置坐标，可获得第一运动轨迹。其中第一参考坐标系是运动传感器的内参坐标系。应理解，运动传感器根据第一参考坐标系确定电子设备的运动轨迹可能并不是电子设备的实际运动轨迹，例如运动传感器根据第一参考坐标系确定电子设备向左移动，而实际上电子设备向右移动。所以之后手机将第一运动轨迹从第一参考坐标系映射到第二参考坐标系，获得第二运动轨迹，即手机100的实际运动轨迹。应理解，第二参考坐标系为大地坐标系。
为了便于理解，请参见图12，为相邻两个第二数据形成轨迹的示意图。在图12中以运动传感器是光学摄像头为例，即以确定光学摄像头的运动轨迹为例。应理解，运动传感器是光学摄像头，相邻两个第二数据实际上是相邻两帧第二数据。不同形状的图块中每个图块均表示光学摄像头拍摄的照片上的特征点，也就是第二数据内的特征点。在第一参考坐标系中，可分别计算相邻的两个第二数据在第一参考坐标系中的位置坐标，从而可以获得相邻的两个第二数据在第一参考坐标系中的第一运动轨迹。或者，也可认为在第一参考坐标系中，可分别计算光学摄像头拍摄的照片上相邻的两个特征点在第一参考坐标系中的位置坐标，从而可以获得相邻的两个特征点在第一参考坐标系中的第一运动轨迹。将该第一运动轨迹映射到第二参考坐标系中，即可得到光学摄像头的实际运动轨迹，即手机100的实际运动轨迹。
S405、将第一数据和第二数据进行匹配，基于匹配结果生成非视距物体的电磁图像数据。
应理解，手机100在移动过程中，电磁传感器持续采集来自非视距物体的第一数据，在一段时间内，电磁传感器采集的第一数据可包括N个第一采样数据。每个第一数据的采样时刻对应一个物理空间位置，由于每个第二数据的采样时刻也对应一个物理空间位置。那么在手机100的实际运动轨迹上的每个物理空间位置均对应一个第一数据和一个第二数据。所以手机100可将第一数据和第二数据进行匹配，基于匹配结果可生成非视距物体的电磁图像。
将第一数据和第二数据进行匹配，换句话说，是将第一数据包括的N个第一采样数据和第二数据包括的M个第二采样数据对齐，也就是将N个第一采样数据和M个第二采样数据在采集时刻上对齐。应理解，当第一数据和第二数据的采样速率相同时，既N＝M，那么第一数据和第二数据自然是对齐的，此时无需任何对齐操作。
而第一数据和第二数据采样速率不相等时，即N不等于M，可通过线性差值或抽取方式将N个第一采样数据和M个第二采样数据对齐。例如在N个第一采样数据中插入M-N个第三数据或在M个第二采样数据中插入N-M个第三数据，再将同一采集时刻的第一数据和第二数据对齐。举例来说，假设第一数据的采样速率为K1Hz，第二数据的采样速率为K2Hz，K1＝2*K2,那么有N＝K1/K2*M，因此，可以N个第一采样数据每间隔K1/K2 抽取一个数据，从而N个第一采样数据变成M个第一数据，与第二数据的个数相同，一一匹配即可。或在M个第二采样数据每间隔K1/K2插入一个数据，从而M个第二采样数据变成N个第二数据，与第一数据的数量相同，一一匹配即可。
例如，第一数据记为
Figure PCTCN2021075658-appb-000005
其中，A为回波信号的幅度，
Figure PCTCN2021075658-appb-000006
为回波信号的相位，第一数据的采样速率为K 1Hz，手机100累计的移动时长为T秒。手机100在T秒内采集的第一数据的集合可表示为：
Figure PCTCN2021075658-appb-000007
其中，N＝K 1*T。
当K 1＝K 2，N＝M，也就是N个第一采样数据的数目等于M个第二采样数据的数目，当K 1不等于K 2，可采用插值方法将N个第一采样数据和M个第二采样数据一一匹配。对N个第一采样数据和M个第二采样数据匹配后，此时第一数据可记为:
Figure PCTCN2021075658-appb-000008
令用于非视距物体成像的数据集合为：
Figure PCTCN2021075658-appb-000009
那么有
Figure PCTCN2021075658-appb-000010
其中，λ表示回波信号的波长，λ i,j表示手机100与非视距物体之间的距离，
Figure PCTCN2021075658-appb-000011
用于计算θ，
Figure PCTCN2021075658-appb-000012
用于计算ψ。
将非视距物体的成像的电磁图像数据集合输出给手机100，如图13所示，可获得最终的图像。
S406、在取景界面中显示所述最终图像。
手机100可输出生成非视距物体的电磁成像，也就是最终图像，从而在取景界面中显示该最终图像。需要说明的是，手机100在显示相机应用的取景界面时，电磁传感器可以实时地采集图像，手机100可以在电磁传感器每次采集图像都采用上述过程(具体是S505)，得到最终图像，并将最终图像显示在取景界面中。也就是说，相机应用的取景界面中的预览图像是手机100根据电磁传感器采集的图像通过上述S505得到的图像。
需要说明的是，由于不同的扫描图样对应的成像性能所有不同，如果预览图像的成像效果可能较差，可能是由于用户选择采用的扫描图样的原因。这种情况下，用户可以选择不存储最终图像，而是重新选择扫描图样，以获得成像性能较好的最终图像。
在一种可能的场景中，例如安检场景中，目前的安检设备对非视距物体的电磁成像可供用户对非视距物体的轮廓等信息，例如行李箱中的药瓶，但是无法给出药瓶中药品的成份，需要用户打开药瓶对药品进行检测。在本申请实施例中，最终图像除了显示非视距物体的电磁成像结果，还可以显示该非视距物体的材质信息，例如金属、木头、液体，进一 步的，例如铁、金、乙醇等。应理解，手机100的显示界面的一个显示区域用于显示非视距物体的电磁成像结果，另一个显示区域显示材质信息，不需要用户对非视距物体的材质进一步验证，提升用户体验。
具体的，手机100获取第一数据之后，可以确定该第一数据对应的频谱。由于不同材质的物体的反射和穿透特性不同，所以手机100接收的第一数据呈现不同的频谱曲线。手机100可以根据第一数据对应的频谱，以及频谱和材质的对应关系确定非视距物体的材质。应理解，手机100可存储频谱和材质的对应关系，或者手机100确定第一数据对应的频谱之后可以告知其他设备，该设备存储有频谱和材质的对应关系，可以确定非视距物体的材质，之后该设备将确定的材质告知手机100。
示例2：手机100多视角拍摄图像。
考虑到拟成像物体的体积较大或者遮挡拟成像物体的遮挡物的体积较大，例如图3所示的盒子的体积较大，而手机100每次拍摄的视角有限，那么拍摄一次，无法实现对非视距物体的成像。这种情况下，手机100可以对非视距物体多次拍摄，每次拍摄可以对应调整手机100相对非视距物体的位置，也就是调整手机100的拍摄视角，实现对非视距物体的成像。
示例2与示例1的不同之处在于，在手机100进入第一成像模式之后，在S503中的第三操作是指示多视角拍照或者全景成像的操作。
在一些实施例中，该第三操作可以是点击相机显示界面中的多视角拍照图标或者全景成像图标的操作。应理解，本申请实施例不限制第三操作对应的图标的名称，例如多视角拍照图标和全景成像图标。当然，第三操作也可以是其他操作，例如在取景显示界面下滑的操作或者长按音量键的操作，指示多视角拍照，本申请实施例对第三操作不作限制。应理解，电子设备检测到该第三操作，可启动多视角模式，也就是从多个视角对非视距物体进行拍摄的模式。
应理解，手机100进入多视角模式之后，也可在显示界面显示辅助提示信息，具体的参见示例1的相关描述，这里不再赘述。手机100进入多视角模式之后，从多个视角对非视距物体进行拍照，可以理解为手机100从各个视角对非视距物体进行二维扫描，获得各个视角的二维电磁图像，之后将各个视角的二维电磁图像进行拼接，获得最终图像。
为了便于理解，请继续参见图14，为多视角成像的一种示意图。图14以从3个视角对非视距物体进行拍摄为例。结合图15，手机100的显示界面显示辅助提示信息之后，手机100检测到输入的第四操作时，例如点击相机显示界面中的拍照图标的操作，通过电磁传感器采集第一数据，通过至少一个运动传感器采集第二数据，直到检测到输入的第五操作，例如点击相机显示界面中的“暂停”图标的操作，停止通过电磁传感器采集第一数据和/或停止通过至少一个运动传感器采集第二数据。应理解，从第四操作到第五操作，手机100完成在一个视角的拍照。
之后手机100运动到第二个视角，手机100检测到输入的第六操作，例如点击相机显示界面中的“开始”图标的操作，通过电磁传感器采集第一数据，通过至少一个运动传感器采集第二数据，直到检测到输入的第七操作，例如点击相机显示界面中的“暂停”图标的操作，停止通过电磁传感器采集第一数据和/或停止通过至少一个运动传感器采集第二数据。即完成手机100在第二个视角的拍照。手机100完成第三视角的拍照与完成手机100在第 二个视角的拍照类似，这里不再赘述。需要说明的是，“暂停”图标和“开始”图标可以是同一个图标，不同之处在于，图标的具体样式不同。又例如，手机100可间歇性地移动，即手机100从静止状态变更到运动状态，又从运动状态变更到静止状态，再从静止状态变更到运动状态，如此等等。这种情况下，手机100如果检测到手机100从静止状态变更到运动状态，则手机100开始通过电磁传感器采集第一数据，并通过至少一个运动传感器采集第二数据；手机100如果检测到手机100从运动状态变更到静止状态，则手机100停止通过电磁传感器采集第一数据和/或停止通过至少一个运动传感器采集第二数据，以此类推，手机100可以获得多个视角的图像。
应理解，手机100每获得一个视角的电磁图像，可以存储该电磁图像，即存储非视距物体在各个视角的电磁图像，之后手机100可对多个视角的电磁图像进行拼接，获得最终图像。具体的，以包括4个视角的图像为例，这4个视角的图像分别为第一视角下的第一电磁图像，第二视角下的第二电磁图像，第三视角下的第三电磁图像，以及第四视角下的第四电磁图像。手机100可以依次将第一电磁图像、第二电磁图像、第三电磁图像和第四电磁图像进行拼接。例如手机100可以按照拍摄的起始时刻的先后顺序将第一电磁图像、第二电磁图像、第三电磁图像和第四电磁图像进行拼接。或者，用户可以多个视角的电磁图像选择部分电磁图像进行拼接，获得最终的图像。应理解，尽管手机100存储了多个视角的电磁图像，但是用户可以从这多个视角的电磁图像中选择部分电磁图像用于拼接。关于图像拼接可参考现有的拼图软件实现，这里不再赘述。
手机100显示最终图像之后，可以删除之前存储的非视距物体在各个视角下的电磁图像，以尽量节约手机100的存储空间。例如手机100可以根据用户的实际需求，删除非视距物体在各个视角下的电磁图像中的部分图像。例如存在多个电磁图像，当手机100检测到输入的第八操作，响应于该第八操作，删除多个电磁图像中的部分或全部电磁图像。即根据用户的需求包括部分电磁图像，方便用户以后查看。
本申请实施例的非视距物体的成像方法，在对非视距物体成像时，可移动电子设备。由于电子设备移动，相当于第一组件移动，形成虚拟的较大的天线阵列，所以可实现较宽的波束扫描范围，从而提升电磁成像的成像分辨率。且通过较小体积的电子设备即可实现较宽的波束扫描范围，所以可通过便携设备实现对多种应该场景下的非视距物体的成像。例如通过手机可实现对较大体积的非视距物体的成像；又例如通过车载设备也可实现对非视距物体，例如另一车辆遮挡的物体的成像，有助于行车安全。
上述本申请提供的实施例中，从电子设备(手机100)作为执行主体的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，终端设备可以包括硬件结构和/或软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能以硬件结构、软件模块、还是硬件结构加软件模块的方式来执行，取决于技术方案的特定应用和设计约束条件。
