本发明涉及一种体温测试方法、装置和智能设备。
背景技术
常见的体温测试仪是接触式体温测试仪，用于测试用户的腋下或者口腔的温度值，但是，接触式体温测试仪的使用对象受限，例如对儿童的使用不方便。现有技术中有一种非接触式的红外测温仪，可以测试用户的额头或者耳朵的温度，但是目前非接触式的红外测温体的工作距离只有3厘米左右，无法满足远距离测温的需求。
发明内容

根据本发明的一个方面，提供了一种体温测试方法，包括：
在接收到测温指令时，开启摄像头以及第一红外测温仪；
通过摄像头对用户进行拍照得到图像，对图像进行识别，确定用户的待测部位；
获取第一红外测温仪与用户之间的距离；
在距离与预设距离阈值一致时，控制第一红外测温仪测量用户的待测部位的温度；其中，预设距离阈值根据第一红外测温仪的菲涅尔透镜的焦距设置；

微处理器，在接收到测温指令时，开启摄像头以及第一红外测温仪；
摄像头，启动后对用户进行拍照得到图像，将图像发送至微处理器；
微处理器，根据接收到的图像确定出用户的待测部位，并根据获取的第一红外测温仪与用户之间的距离，在判断出距离与预设距离阈值一致时，控制第一红外测温仪测量用户的待测部位的温度，对温度进行处理，得到用户体温值或用户体温值范围；其中，预设距离阈值根据第一红外测温仪中的菲涅尔透镜的焦距设置。
根据本发明的又一个方面，提供了一种智能设备，该智能设备包括机器可读存储介质和处理器，机器可读存储介质和处理器之间通过内部总线通讯连接，机器可读存储介质存储有能够被处理器执行的计算机程序，计算机程序被处理器执行时促使实现本发明的一个方面的一种体温测试方法的步骤。
本发明实施例的有益效果是：本发明实施例的体温测试方案，由于对用户拍照得到的图像进行图像识别后确定待测部位，并对用户和第一红外测温仪之间的距离进行判断，在距离与预设距离阈值一致时，控制第一红外测温仪测量待测部位的温度，实现了远距离体温测量，使用对象不受限制；且预设距离阈值是根据第一红外测温仪的菲涅尔透镜的焦距设置的，即只有当用户处于焦距附近的位置处时，才进行体温测试，提高了体温测试结果的准确度和可靠性；结合对摄像头拍摄的图像的识别，确定出待测部位，并测试待测部位的温度，根据预设规则和待测部位的温度，将待测部位的温度换算为用户的体温值，减小了人体不同部位间的温度测试误差，进一步提高了测试出的用户体温的准确性。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。
图1是本发明一个实施例的体温测试方法的流程示意图；
图2是本发明一个实施例的实现体温测试的相关硬件的设置位置示意图；
图3是本发明一个实施例的体温测试方法的流程图；
图4是本发明一个实施例的体温测试方法的流程图；
图5是本发明一个实施例的体温测试的示意图；
图6是本发明一个实施例的体温测试装置的结构框图；
图7为本发明一个实施例的智能设备的结构框图。
具体实施方式
现有常见的体温测试仪是接触式体温测试仪，也有一种非接触式红外测温仪，本申 请的发明人发现当使用非接触式红外体温测试仪进行远距离(例如，距离超过20cm)的测量时精度往往无法保证，经实验，这种非接触式红外体温测试仪的测量误差一般大于1摄氏度。如果将一个38摄氏度正在发烧的儿童的体温错误地测量为37摄氏度的正常体温，则这种测量结果是无效且危险的。
目前，影响红外体温测量精度的因素主要有：
(1)当远距离测量体温时，红外传感器需要加上菲涅尔透镜才能获取远处物体的红外光强度实现体温测试，而由于菲涅尔透镜的焦点是确定的，只有在菲涅尔透镜的焦距附近处的物体的测试结果才是可靠的。例如，当选择焦距为50厘米的菲涅尔透镜时，在50厘米远处焦点对应的位置能够测试到用户的待测部位(如额头)上一个点的温度，当偏移焦点处，红外传感器测量得到的将是额头上一个面的平均温度，焦点与用户之间的距离偏离所述焦点越远，测量的面越大(例如，比额头的面积大)，测试结果越不准确。
(2)不同的物体，由于其红外发射率不同，相同温度下向外辐射的红外线能量也不同。例如，同样为37摄氏度的人体皮肤和墙面，辐射出来的红外线能量有很大差别。因此需要考虑人体的待测部位和体温之间的温度差异，以得到精确的体温值。
(3)红外线能量传输还跟实际环境因素(如环境中的温度、湿度、灰尘浓度等等)有很大的关系，测试距离越远，受到的环境影响就越大，测试结果就越不精确。在远距离测试时，如何保证测试精度是亟需解决的问题。
考虑到上述影响红外体温测试精度的因素和技术问题，本发明实施例提供了一种体温测试方法，以提高红外体温测试时的测试精度并且实现远距离、非接触式体温测试。
应当明确，下述所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
参见图1，本实施例的体温测试方法包括如下步骤：
步骤S101，在接收到测温指令时，开启摄像头以及第一红外测温仪；
步骤S102，通过摄像头对用户进行拍照得到图像，对图像进行识别，确定用户的待测部位；
步骤S103，获取第一红外测温仪与用户之间的距离；
步骤S104，在距离与预设距离阈值一致时，控制第一红外测温仪测量用户的待测部位的温度；其中，预设距离阈值根据第一红外测温仪的菲涅尔透镜的焦距设置；。
步骤S105，根据预设规则以及测量得到的温度，确定用户体温值或用户体温值范围。
由图1可知，本实施例的体温测试方法，利用摄像头对用户进行拍照得到图像，并对图像进行识别确定出待测部位。根据获取的第一红外测温仪和用户之间的距离判断该距离是否与预设距离阈值一致，如果一致则控制第一红外测温仪测量用户的待测部位的温度，进而实现远距离体温测量，使用对象不受限制。并且，在第一红外测温仪和用户之间的距离等于菲涅尔透镜的焦距处对用户待测部位进行测试，保证了红外测试距离，避免了红外测试时红外测温仪的中心线偏离菲涅尔透镜的焦点导致的测试误差，提高了测试结果的准确性。进一步的，针对人体不同部位之间存在温度差异这一因素的影响，本实施例中当测量得到用户的待测部位的温度值后，不是直接将其作为用户的体温值，而是根据预设的规则将用户的待测部位的温度值换算为用户的体温值，保证得到更精确的体温值。
上述步骤S103中获取第一红外测温仪与用户之间的距离的一种可行方式是通过距离传感器(例如超声波距离传感器)。可以理解，获取距离的可行方式不限于通过距离传感器，也可以采用其它方式，例如，获取由用户直接输入的用户与第一红外测温仪的距离。这种情况下，应用本实施例的体温测试方法的装置中具有用户交互功能，基于该用户交互功能，接收用户输入的用户与装置中的第一红外测温仪的距离。再例如，通过拍摄图像并对图像进行处理的方式获取第一红外测温仪与被拍摄物体(即，用户)的距离。
上述步骤S102中确定用户的待测部位可以是确定用户的耳朵部位，鼻子部位，额头部位等，本发明实施例对此不做限定。
本发明实施例的体温测试方法可以应用于多种产品中，例如，智能音响，智能电视机，服务机器人等，本发明不做限定。以下以服务机器人为例进行具体说明。
考虑到服务机器人与用户之间在进行沟通时，两者距离太近会给用户带来不舒适感，不符合实际应用需求，而两者距离太远时，由于红外线能量传输易受周边环境中的温度、湿度以及粉尘颗粒物等的影响，距离越远，误差越大，测试结果越不准确；另外，由于额头部位测试相对简单并且额头通常比较平坦，辐射的红外线能量比较均匀，测试误差小，测试数据更准确。所以这里以用户的待测部位为额头作为本发明实施例的优选方式，并选 择菲涅尔透镜的焦距长度为50厘米(cm)。
下面就以体温测试方法应用于服务机器人，用户的待测部位为用户的额头为例进行具体说明。
参见图2，在服务机器人上设置第一红外测温仪、摄像头和距离传感器，三者放置在一起，并保证三者的中心线聚合在第一红外测温仪的菲涅尔透镜的焦点处，例如三者的中心线在菲涅尔透镜焦距L等于50cm对应的位置处会聚。
需要说明的是，作为优选的方式的图2示意的是第一红外测温仪在上方，摄像头在中间以及距离传感器在下方的位置结构。将第一红外测温仪、摄像头和距离传感器三者放置在一起，并保证三者的中心线在第一红外测温仪的菲涅尔透镜的焦点处聚合是本发明实施例的一种可行的方式，这样的设计可以实现第一红外测温仪在菲涅尔透镜的焦距指示的距离处测量得到用户额头上一个测试点的温度值，而测试点的温度值比测试面的温度值的误差更小，测试结果更精确，即，提高了测试精度。
实际应用中，如果对测量精度需求较低，也可以相对随意的设计第一红外测温仪、摄像头和距离传感器的位置，只需保证三者的中心线聚合在第一红外测温仪的菲涅尔透镜的焦点处。另外，本发明实施例对三者的放置顺序没有严格限定，即可以对图2中三者的放置顺序进行变形，例如，在本发明的其它实施例中，可以将摄像头放置在上方，第一红外测温仪放置在中间，以及将距离传感器放置在下方，并保证三者的中心线在第一红外测温仪的菲涅尔透镜的焦点处会聚。或者，还可以将摄像头放置在下方，将距离传感器放置在中间，并将第一红外测温仪放置在下方。
也就是说实际应用中，可以根据需求调整三者的放置位置，不限于此。具体的调整方式，既可以是对三者的放置位置的顺序进行调整，也可以是在不调整放置位置顺序的情况下，调整三者中某一个部件的放置角度，例如，调整摄像头的放置角度以将摄像头的中心线在第一红外测温仪的菲涅尔透镜的焦点处会聚。
参见图3，在接收到测温指令时，本实施例的体温测试方法包括如下具体步骤，流程开始，
执行步骤S300，开启距离传感器；
为了实现对用户体温的测试，本实施例中需要获取用户和服务机器人之间的距离， 因而在应用时可以先开启服务机器人上的距离传感器而后执行步骤S301。
步骤S301，开启摄像头拍照，并进行人脸识别；
开启摄像头，摄像头采集服务机器人前方的物体的图像以发现待进行体温测试的目标对象(即用户)。
步骤S302，判断用户的脸部是否处于画面中心；若是，则确定出用户的待测部位为额头部位，执行步骤S303，若否，则返回执行步骤S301；
本步骤中之所以判断用户的脸部是否处于画面中心，是为了确定用户目前正注视服务机器人，并从画面中识别出用户脸部区域进而确定出额头这一待测部位，当用户的脸部未处于画面中心时，往往表明用户当前未注视服务机器人上的摄像头而是看向其它物体，这时，不便于对用户进行温度测试。
服务机器人上的微处理器对摄像头采集的图像进行人脸识别，例如，通过图像中对应用户脸部区域的像素坐标信息，判断是否有用户近距离面向摄像头，即，判断用户的脸部是否处于画面中心，在是的情况下，确定出额头部位并保证第一红外测温仪对准用户的额头。需要说明的是，微处理器对图像进行人脸识别可以采用现有技术中的任何一种可行的方案，对此不作限制，只要能够根据摄像头采集的用户的图像识别出用户的人脸区域即可。
步骤S303，通过距离传感器测量得到第一红外测温仪与用户之间的距离；
本步骤中通过距离传感器，例如超声波传感器测量用户与第一红外测温仪之间的距离。需要说明的是，由于第一红外测温仪设置在服务机器人内，所以，进行距离测量时，可以测量服务机器人与用户之间的距离并等同于用户与第一红外测温仪之间的距离。在其他实施例中，距离获取方式可采用其它可行的方式，例如前述说明的由用户直接输入距离的方式，或者利用拍摄图像并进行图像处理得到距离的方式，不限于此。
步骤S304，判断距离是否与预设距离阈值一致，是则执行步骤S305；否则返回执行步骤S303；
本步骤中，判断步骤S303中获取的第一红外测温仪与用户之间的距离是否与预设距离阈值一致，当测试得到的距离与预设距离阈值50cm一致(允许有1cm误差)时，通知第一红外测温仪测试用户的额头的温度。
实际应用中，当测量得到第一红外测温仪与用户之间的距离与预设距离阈值不一致时，控制服务机器人移动到相应的位置，或控制输出提醒信息至用户提醒用户移动到相应的位置。例如，当测试得到的第一红外测温仪与用户之间的距离大于预设距离阈值(比如50cm)时，可控制服务机器人移动或提醒用户移动以缩小服务机器人与用户之间的距离。
考虑到本实施例的体温测试方法的应用场景，以及第一红外测温仪与用户之间的距离可能大于预设距离阈值的现实，本申请实施例提出了如上述的两种不同的缩短距离的方式以满足不同场景下的需求。具体的，对于应用于服务机器人这一类可以移动的装置而言，既可以通过控制服务机器人移动，用户保持不动的方式来缩短服务机器人与用户之间的距离，也可以在控制服务机器人移动的同时提醒用户移动以快速缩短两者之间的距离。而对于使用时不便移动的产品，例如，智能电视机而言，本实施例可以通过控制输出提醒信息至用户，提醒用户移动到相应的位置的方式来缩短两者之间的距离。
在控制服务机器人和/或用户移动后，本实施例记录测试距离为50cm时的第一红外测温仪的测试结果。即，先控制服务机器人和/或用户移动，只有在服务机器人和/或用户移动到指定位置(测试距离50cm对应的位置)后，控制第一红外测温仪测量得到一个温度值。
另外，在其他实施例中，当进行人脸识别确定出摄像头对准的是用户额头后，可以控制第一红外测温仪实时测试用户额头的温度，得到多个温度值，在此过程中，控制距离传感器实时检测用户和服务机器人之间的距离，从而只保留用户和服务机器人之间距离为50cm(或者误差在正负1cm内)时对应的温度值。即，控制第一红外测温仪测量得到多个温度值，只取两者距离为50cm(或者误差在正负1cm)时对应的温度值。
步骤S305，控制第一红外测温仪测试用户的额头的温度，得到第一温度值；
第一红外测温仪的工作原理是温度在绝对零度以上的物体，都会因自身的分子运动而辐射出红外线，物体的温度越高，所辐射出的红外线越强，利用人体不同部位发出特定波段的红外线来测量出人体部位的温度。本步骤中，控制第一红外测温仪测量用户的额头的温度，得到用户的额头温度值，即第一温度值。
步骤S306，根据预设的额头温度与体温转换规则，确定第一温度值对应的用户体温值或用户体温值范围。
本步骤中，在得到第一温度值之后，根据预设规则比如下列的表1进行转换，即，将测量到的用户的额头部位的温度值准确转换为体温值。
这里的预设规则为额头温度和体温转换规则，实际应用中例如维护额头温度和体温转换表(即表1)，表1中记录了额头温度及其对应的用户体温值或体温值范围，示意性的，表1中记录了额头温度为33.2摄氏度时对应的用户体温值为35.5摄氏度，额头温度为33.4摄氏度时对应的用户体温值为35.7摄氏度，额头温度为35摄氏度时对应的用户体温值为37摄氏度。
需要说明的是，这里是以一个额头温度值对应一个体温值进行的说明，其它实施例中，一个额头温度值也可以对应一个体温值范围，例如，额头温度为33.2摄氏度时对应的用户的体温值范围为35.1摄氏度—35.9摄氏度这一范围，对此不作限制。
Figure PCTCN2018088198-appb-000001
表1
表1为额头温度与人体体温的对照表，在得到第一体温值即额头温度之后，通过查找额头温度和人体体温转换表，即可确定出对应的用户体温。至此，流程结束。
考虑到实际应用时，环境因素等对体温测试结果会造成干扰和影响，在另一个实施例中，为了改善测试环境中湿度、温度以及粉尘颗粒对于温度测试结果的影响，提高测试精度，提出设置温度已知且固定的参照物，并利用参照物和用户额头的测量温度综合确定用户的体温的方案，以减小测试误差，提高测试准确性。
这里先对参照物的结构以及参照物所处的环境和距离的设置进行说明。
接上例，本实施例的参照物设置在服务机器人上，包括皮质表面(皮质表面与人体皮肤较接近，可减少测试误差)，发热器以及温度反馈控制电路。参照物的皮质表面温度固定，例如，将温度设定为人体额头的一般温度，即35摄氏度。在参照物的皮质表面内设置有发热器和温度反馈控制电路。发热器作为热源可以产生热能，温度反馈控制电路的作用是检测参照物当前的温度，如果参照物当前的温度超过了设定的温度值(例如35摄氏度)，则控制发热器停止发热，等待温度下降。当参照物的温度下降到35摄氏度以下时，则控制发热器发热，如此，将参照物的温度值维持在设定的温度值。
另外，为了准确的确定环境因素对体温测试的影响程度，以将这一部分影响因素剔除，减小测试误差。本实施例中根据用户所处的环境模拟构建参照物所处的环境。具体的，在服务机器人内对应参照物的设置位置，设计合理的通风结构，让参照物所在的服务机器人的内部环境与用户所处的服务机器人的外部环境保持一致。例如，在服务机器人对应参照物的位置处设置通风口，这样，用户所处环境(例如室内)中的气体进入服务机器人内，使得参照物所处环境与用户所处环境一致。由于只设置一个通风口，空气流动范围和影响范围有限，因而，也可以设计风道，即，设置一个进风口和一个通风口，保证空气的循环对流。并且可以在服务机器人的远离电路板等热源的空旷位置设置隔离箱，将参照物放置在隔离箱内，避免服务机器人工作过程中，服务机器人内部发出的热能对参照物的温度造成影响，以提高对用户体温测试的精度。
本实施例的参照物单独对应一个红外测温仪，称为第二红外测温仪，利用第二红外测温仪对参照物的温度进行测量。
考虑到测试距离也会对参照物的测试温度造成影响，本实施例中将参照物设置在与 第二红外测温仪相距预设距离阈值的位置处，这里的预设距离阈值是根据第一红外测温仪的菲涅尔透镜的焦距设置的，如此设计能够保证两个红外测温仪测量的是相同距离远处的用户或参照物的温度，从而避免了距离不同导致的测试结果误差。
在设置参照物之后，接下来对利用参照物的测试温度减小测试误差的本实施例的体温测试的方法进行说明。
参见图4，本实施例的体温测试的方法包括如下步骤：流程开始，
执行步骤S400，开启距离传感器；
为了方便后续获取用户和服务机器人之间的距离，因而该方法在实施时可以先开启服务机器人上的距离传感器而后执行步骤S401。
步骤S401，开启摄像头拍照，并进行人脸识别；
步骤S402，判断用户的脸部是否处于画面中心；是则，确定出用户的待测部位为额头部位，执行步骤S403，否则返回执行步骤S401；
步骤S403，通过距离传感器测量得到第一红外测温仪与用户之间的距离；
步骤S404，判断距离是否与预设距离阈值一致，是则执行步骤S405和步骤S406；否则返回执行步骤S403；
步骤S405，控制第一红外测温仪测试用户的额头的温度，得到第一温度值；
需要说明的是，本实施例的步骤S401至步骤S405与前述实施例的图3中的步骤S301至步骤S305是相同的，因而本实施例中步骤S401至步骤S405的更详细内容参见前述图3对应的步骤中的说明，在此不再赘述。
与前述图3对应的实施例所不同的是本实施例中的步骤S406至步骤S409，以下重点说明。
步骤S406，控制第二红外测温仪测试参照物的温度得到第二温度值；
本步骤中，通过第二红外测温仪对服务机器人内的参照物的温度进行测试，得到第二温度值。虽然参照物的温度是已知的和固定的，但是实际测量时，受环境影响，通过第二红外测温仪测量得到的温度值和参照物的实际温度之间肯定存在一个误差，误差体现了测试环境对体温测试结果的影响程度。
步骤S407，根据第一温度值和第二温度值计算得到第三温度值；
在分别通过步骤S405和步骤S406得到第一温度值和第二温度值的基础上，根据第一温度值和第二温度值计算得到第三温度值。具体的，计算公式如下：
Figure PCTCN2018088198-appb-000002
其中，C为第三温度值，A为第一温度值，B为第二温度值，e为参照物的固定温度值(例如35摄氏度)。
这里，为了避免用负数和0表达温度，对温度值的计算都是在物体的热力学温度为标定和量化的基础上进行的，例如，两个物体的温度值相乘，如果用摄氏度来表示，其中一个物体的温度值为0℃时，那么两者相乘的结果将为0摄氏度，但实际上两个指示温度的数值相乘之后应比其中一个指示温度的数值要大，即比其中一个物体的温度值高，可见，如果用摄氏度表示温度值会出现无法计算的问题。基于此，本实施例中将测量得到的第一温度值以及第二温度值都换算为对应的绝对温度并进行计算后得到第三温度值。
步骤S408，根据预设的额头温度与体温转换规则，确定第三温度值对应的用户体温值或用户体温值范围；
本步骤中，在得到第三温度值之后，与前述步骤S306类似的，根据预设的额头温度与体温转换规则，查找前述表1即可确定出第三温度值对应的用户体温值或用户体温值范围。
步骤S409，对用户体温数据进行筛选后保存；
本步骤中对用户体温数据进行筛选，去除不合理的数据，把筛选后的体温数据发送至服务机器人中的人体健康应用使用。这里的不合理的数据包括超出预设范围(如35摄氏度到40摄氏度)的体温数据。比如，用户额头露出来，测试得到的额头温度是34.6摄氏度，根据额头温度和体温转换规则，对应的体温为36.7摄氏度，这条数据可保留。而当该用户额头上存在遮挡物(如用户的头发)时，测试得到的额头温度约为31摄氏度，根据额头温度和体温转换规则，对应的体温数据约为34摄氏度，超出了35摄氏度到40摄氏度的温度范围，即为不合理的数据。另外，在一些特别极端的条件下，例如室温为零下10度或者室温超过40摄氏度，此时测试得到的额头温度结果非常极端，例如超过40摄氏度，则这些不合理的数据需要筛除掉。
至此，流程结束。
需要强调的是，前述图3和图4所示实施例中是以先开启距离传感器，后开启摄像头对用户进行拍照后，再通过距离传感器获取第一红外测温仪和用户之间的距离进行的说明，但本发明实施例不限于此，例如，可以先开启摄像头对用户进行拍照根据图像确定出用户的待测部位，后开启距离传感器并利用距离传感器获取第一红外测温仪和用户之间的距离，当两者之间的距离与预设距离阈值一致时再控制红外测温。实际应用中，可以根据需求进行设置和选择。
图5是本发明一个实施例的体温测试的示意图，参见图5，在摄像头，第一红外测温仪和距离传感器的配合下，测量得到的表示用户额头温度的测试结果A，即第一温度值输入到微处理器，通过第二红外测温仪测量得到的表示参照物的温度的测试结果B，即，第二温度值也输入到微处理器中。微处理器，根据第一温度值和第二温度值计算得到第三温度值，并根据预设的额头温度与体温转换规则，确定第三温度值对应的用户体温值或用户体温值范围。
与前述体温测试方法相对应的，本实施例提供了一种体温测试装置，参见图6，体温测试装置600包括：装置本体、设置在装置本体上的微处理器601，与微处理器601连接的摄像头602以及第一红外测温仪603；
微处理器601，在接收到测温指令时，开启摄像头602以及第一红外测温仪603；
摄像头602，启动后对用户进行拍照得到图像，将图像发送至微处理器601；
微处理器601，根据接收到的图像确定出用户的待测部位，并根据获取的第一红外测温仪603与用户之间的距离，在判断出距离与预设距离阈值一致时，控制第一红外测温仪603测量用户的待测部位的温度，对温度进行处理，得到用户体温值或用户体温值范围；
其中，预设距离阈值根据第一红外测温仪603中的菲涅尔透镜的焦距设置。
一个实施例中，体温测试装置600还包括距离传感器，距离传感器与微处理器601连接；
距离传感器，第一红外测温仪603以及摄像头602均设置在装置本体上，且三者在设置位置上满足各自的中心线在第一红外测温仪603的菲涅尔透镜的焦点处会聚的条件；
距离传感器启动后测量第一红外测温仪603与用户之间的距离，将距离信息发送至 微处理器601，
微处理器601，对接收到的图像进行人脸识别，当识别出人脸区域位于图像的中心位置且在判断出距离与预设距离阈值一致时，控制第一红外测温仪603测量用户的待测部位的温度，得到第一温度值；这里的，用户的待测部位可以为用户的额头部位。
在本发明的一个实施例中，体温测试装置600还包括设置在装置本体上的参照物，参照物包括皮质表面，发热器以及温度反馈控制电路，
参照物的温度反馈控制电路与发热器连接，采集参照物的当前温度值，并根据采集的当前温度值控制发热器，以将参照物的温度值保持在一个固定温度值；
装置本体上对应参照物的位置设置有通风口和风道；
装置本体上与参照物距离固定且等于预设距离阈值处设置有第二红外测温仪，
第二红外测温仪与微处理器601连接，第二红外测温仪在微处理器601的控制下测量参照物的温度，得到第二温度值；
微处理器601具体用于根据预设规则、第一温度值和第二温度值，确定用户体温值或用户体温值范围。
例如，微处理器601，根据第一温度值和第二温度值计算得到第三温度值，根据预设的额头温度与体温转换规则，确定第三温度值对应的用户体温值或用户体温值范围并保存到存储器中；以及对存储器中的用户体温值或用户体温值范围进行筛选，选出处于预设温度值范围内的用户体温值或用户体温值范围。
一个实施例中，装置本体为服务机器人，距离传感器，第一红外测温仪603以及摄像头602设置在服务机器人的头部。
体温测试装置600还包括：
驱动模块(例如电机)，驱动模块与微处理器601连接，
微处理器601，还用于判断出测量得到第一红外测温仪603与用户之间的距离与预设距离阈值不一致时，控制驱动模块驱动服务机器人移动到相应的位置，和/或，
提醒模块，提醒模块与微处理器601连接，
微处理器601，判断出测量得到第一红外测温仪603与用户之间的距离与预设距离阈值不一致时，控制提醒模块输出提醒信息至用户，提醒用户移动到相应的位置。
也就是说，本发明实施例中可只设置驱动模块，通过控制驱动模块来驱动服务机器人运动实现第一红外测温仪与用户之间距离的改变，例如，第一红外测温仪与用户之间的距离当前为80厘米，而预设距离阈值为50厘米，经过判断可知，两者不一致，则服务机器人中的微处理器控制驱动模块(例如电机)旋转，电机旋转带动服务机器人的滑轮运动从而使服务机器人运动到距离用户50厘米的位置，微处理器控制电机停止旋转。或者，在本发明的一个实施例中设置提醒模块，当微处理器判断出第一红外测温仪与用户之间的距离和预设距离阈值不一致时，控制提醒模块(例如音频输出模块)输出语音提醒信息，示意性的语音提醒信息可以为“请您向前移动20厘米”，提醒用户移动到相应的位置。或者，在本发明的一个实施例中既设置驱动模块又设置提醒模块，以控制装置和/或用户移动使第一红外测温仪和用户之间的距离等于预设距离阈值，以提高测试的精度。
需要说明的是，本实施例的体温测试装置是和前述实施例中的体温测试方法相对应的，因此，本实施例中体温测试装置的工作过程可以参见前述实施例中的说明，在此不再赘述。
基于与上述实施例相同的发明构思，本发明实施例提供了一种智能设备，如图7所示，图7为本发明一个实施例的智能设备的结构框图，包括机器可读存储介质701和处理器702，机器可读存储介质701和处理器702之间通过内部总线703通讯连接，机器可读存储介质701存储有能够被处理器702执行的计算机程序，该计算机程序被处理器702执行时实现本申请所述的体温测试方法的步骤。
在不同的实施例中，机器可读存储介质701可以是内存或者非易失性存储器。其中非易失性存储器可以是：存储驱动器(如硬盘驱动器)、固态硬盘、任何类型的存储盘(如光盘、DVD等)，或者类似的存储介质，或者它们的组合。内存可以是：RAM(Radom Access Memory，随机存取存储器)、易失存储器、非易失性存储器、闪存。进一步，非易失性存储器和内存作为机器可读存储介质，其上可存储由处理器702执行的计算机程序。
综上，本发明实施例的体温测试方法、装置和智能设备，针对现有技术中体温测试无法满足远距离精确测温需求的问题，通过控制测试距离，减小环境等因素导致的温度测试误差，测量得到用户的待测部位的温度，根据预设规则，将待测部位的温度换算为用户的体温值或体温值范围。既满足了远距离体温测试的需求，又保证了体温测试的准确度。
