Description

热成像摄像机灼伤处理方法及装置
本申请要求于2019年6月11日提交中国专利局、申请号为201910500156.9发明名称为“热成像摄像机灼伤处理方法及装置”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
本申请涉及热成像技术领域，尤其涉及热成像摄像机灼伤处理方法及装置。
背景技术
热成像摄像机为通过非接触式的探测红外能量，并通过图像传感器将红外能量转换为电信号，进而得到图像画面以及温度信息的摄像机。
太阳或其他温度远高于热成像摄像机的测温范围的物体，会导致热成像摄像机中图像传感器的材料特性发生改变，也就是，导致图像传感器被灼伤，也就是，导致热成像摄像机被灼伤，进而导致热成像摄像机采集图像画面异常及测温不准确；当高温物体移出图像画面后，对图像画面进行非均匀性校正，得到正常的图像画面。但由于图像传感器的材料特性恢复需要时间，所以尽管已对图像画面进行了非均匀性校正，热成像摄像机采集的图像画面中依然会出现表征图像传感器被灼伤的痕迹。
为了避免热成像摄像机被灼伤，通用的做法是切入切出一个衰减系数已知的衰减装置(如：小孔或者均匀衰减片)。但这种方式只能实现一档温度的扩展，也就是，在一定程度上，扩大热成像摄像机的测温范围。而对于温度极高的物体，如几千度高温的太阳，即使热成像摄像机中采用了衰减装置，仍有大量的红外能量到达图像传感器上，造成热成像摄像机被灼伤。因而采用衰减装置的方法不能用于预防温度极高物体对热成像摄像机被造成灼伤。

具体实施方式
下面结合附图及具体实施例对本申请再作进一步详细的说明。
为方便理解，给出如下解释：
挡片：热成像摄像机使用的一种用来遮挡图像传感器的均匀面，阻隔来自镜头的成像信息，使图像传感器在对图像画面进行非均匀性矫正(NUC，NonUniformity Correction)时不被镜头的成像信息干扰。挡片处于关闭状态时，挡片阻隔来自镜头的成像信息；挡片处于开启状态时，挡片不阻隔来自镜头的成像信息。这里，成像信息包括物体辐射的红外能量。
单置位挡片：正常状态下处于开启状态，需要对控制线圈持续通电才能关闭的挡片，使挡片处于关闭状态。
双置位挡片：对控制线圈进行短时间通电便可改变状态的挡片，即不需要对控制线圈进行持续通电就可以保持挡片处于开启状态或关闭状态。
灼伤报警信号：在辐射高红外能量的物体进入热成像摄像机采集的图像画面时，由算法产生的报警信息，该报警信息用于告知当前有辐射高红外能 量的物体在图像画面中。
灼伤标记：用于记录当前图像传感器被灼伤的信息，也就是记录当前热成像摄像机被灼伤的信息。
NUC：通过在图像传感器前阻隔来自镜头的成像信息，对热成像摄像机内部的热辐射不均匀信号进行采集和存储，然后在正常成像时，将存储的热辐射不均匀信号作为图像画面的背景数据进行去除，以得到不受热成像摄像机内部热量干扰的图像画面，使热成像摄像机输出正常的图像画面。
热成像摄像机可以为红外热成像摄像机。热成像摄像机由镜头、图像传感器、挡片以及其他部分组成。挡片的位置在图像传感器前方，从而起到遮挡住图像传感器，以便对图像画面进行NUC的目的。
为解决相关技术中不能用于预防温度极高物体对热成像摄像机被造成灼伤的问题，实现对热成像摄像机的自动且不限温度范围的防灼伤处理，本申请实施例提供了一种热成像摄像机灼伤处理方法。
图1为本申请实施例提供的热成像摄像机灼伤处理方法的第一种流程图，其具体步骤如下：
步骤101：获取热成像摄像机的热成像图片。
步骤102：检测热成像图片是否显示出有高温对象出现在热成像摄像机的画面中。
步骤103：确认热成像图片显示出有高温对象出现在画面中，生成灼伤报警信号，并且在当前挡片没有关闭的情况下，关闭挡片。
本申请实施例中，检测到热成像摄像机产生灼伤报警信号，则可确定热成像摄像机被灼伤，具体为热成像摄像机的图像传感器被灼伤，使挡片处于关闭状态。此时，无论成像信息的能量的高低，挡片均可挡住，任何成像信息都不能到达图像传感器上，进而不会继续对图像传感器造成灼伤，避免了对图像传感器造成永久伤害，实现了对热成像摄像机的自动且不限温度范围的防灼伤处理。
在步骤101中，热成像摄像机的热成像图片即为热成像摄像机采集的热成像图片。热成像摄像机可实时采集热成像图片。具体可以为：成像信息从热成像摄像机的镜头进入热成像摄像机的内部，热成像摄像机的图像传感器基于从镜头进入热成像摄像机内部的成像信息生成热成像图片。
在步骤102中，画面为热成像图片的图像画面。检测热成像图片是否显 示出有高温对象出现在热成像摄像机的画面中，具体可以为：热成像摄像机的处理器对热成像图片进行检测，确定热成像图片的图像画面中是否出现高温对象。其中，高温对象可以理解为辐射高红外能量的物体。
在步骤103中，当前挡片是指当前时刻挡片。确认热成像图片显示出有高温对象出现在画面中，生成灼伤报警信号，并且基于灼伤报警信号，在当前挡片没有关闭的情况下，关闭挡片，具体可以为：热成像摄像机的处理器若确定热成像图片的图像画面中出现了高温对象，则生成灼伤报警信号，并且使挡片处于关闭状态。此外，基于灼伤报警信号，若当前时刻挡片处于关闭状态，则可以保持当前挡片的关闭状态。
图2为本申请实施例提供的热成像摄像机灼伤处理方法的第二种流程图，其具体步骤如下：
步骤201：获取热成像摄像机的热成像图片。
步骤202：检测热成像图片是否显示出有高温对象出现在热成像摄像机的画面中。
步骤203：确认热成像图片显示出有高温对象出现在画面中，生成灼伤报警信号，并且在当前挡片没有关闭的情况下，关闭挡片，并启动防护机制NUC计时，且当计时时长达到预设的防护机制NUC计时时长时，执行NUC操作。
上述步骤201与步骤101相同，上述步骤202与步骤102相同，此处不再赘述。
在步骤203中，在确定热成像图片的图像画面中出现了高温对象的情况下，处理器生成灼伤报警信号，并且基于灼伤报警信号，若当前挡片处于开启状态，则关闭挡片，使挡片处于关闭状态。此外，基于灼伤报警信号执行关闭挡片的操作的同时，基于灼伤报警信号，启动防护机制NUC计时。当防护机制NUC计时的时长达到预设防护机制NUC计时时长，则可确定挡片已经完全处于关闭状态，此时对图像画面进行NUC不被镜头的成像信息干扰，处理器对图像画面执行NUC操作。
在本申请的一个实施例中，步骤203中，生成灼伤报警信号之后还可以包括：
A、当用户设定了挡片状态时，判断当前挡片的实际状态是否与用户设定的挡片状态一致。若不一致，则将当前挡片的实际状态更改为用户设定的挡片状态，转至步骤B；若一致，则直接转至步骤B；
B、判断当前挡片的实际状态是否为关闭状态。若是，启动防护机制NUC计时，且当防护机制NUC计时的时长达到预设防护机制NUC计时时长时，执行NUC操作。
在本申请的一个实施例中，步骤203中，在当前挡片没有关闭的情况下关闭挡片之前还可以包括：按照灼伤防护检测周期，检测热成像摄像机是否生成灼伤报警信号。若在灼伤防护检测周期到来时检测到热成像摄像机生成的灼伤报警信号，在当前挡片没有关闭的情况下，关闭挡片。若在灼伤防护检测周期到来时未检测到热成像摄像机生成的灼伤报警信号，则在当前挡片关闭的情况下，开启挡片；若当前挡片处于开启状态，则可以保持当前挡片的开启状态。
在本申请的一个实施例中，步骤203中，关闭挡片的同时还可以包括：启动关闭计时，当关闭计时的时长达到预设关闭时长时，打开挡片，并消除灼伤报警信号。
具体可以为，在确定热成像图片的图像画面中出现了高温对象的情况下，生成灼伤报警信号。基于灼伤报警信号，在当前挡片没有关闭的情况下关闭挡片，并且基于灼伤报警信号，启动关闭计时，当关闭计时的时长达到预设关闭时长时，打开挡片，并消除灼伤报警信号。
在本申请的一个实施例中，步骤203中，生成灼伤报警信号之后还可以包括：当灼伤报警信号消除时，若当前挡片为开启，则启动恢复机制NUC计时，当恢复机制NUC计时的时长达到预设恢复机制NUC计时时长时，执行NUC操作。
具体可以为，在生成灼伤报警信号之后，确定热成像摄像机的图像传感器被灼伤，图像传感器的材料特性发生改变。在灼伤报警信号消除后，若当前挡片处于开启状态，则启动恢复机制NUC计时。当恢复机制NUC计时的时长达到预设恢复机制NUC计时时长时，可确定热成像摄像机的图像传感器的材料特性已经恢复，对图像画面执行NUC操作。
在本申请的一个实施例中，生成灼伤报警信号的同时还可以包括：设置灼伤标记，并将预设恢复机制NUC计时时长设定为预设的恢复机制NUC计时时间表中的第一个计时时长，其中，预设的恢复机制NUC计时时间表中包含有顺序排列的多个依次增加的计时时长；
且，当灼伤报警信号消除时还可以包括：判断是否存在灼伤标记，若存 在，则执行所述若当前挡片为开启，则启动恢复机制NUC计时的动作；
且，当恢复机制NUC计时的时长达到预设恢复机制NUC计时时长时执行NUC操作之后还可以包括：
判断当前的预设恢复机制NUC计时时长是否为预设的恢复机制NUC计时时间表中的最后一个计时时长，若是，消除灼伤标记；否则，将预设恢复机制NUC计时时长设定为预设的恢复机制NUC计时时间表中的下一个计时时长，判断热成像摄像机是否生成灼伤报警信号，若未生成，则返回所述判断是否存在灼伤标记的动作。
具体可以为，在确定热成像图片的图像画面中出现了高温对象的情况下，生成灼伤报警信号。在检测到灼伤报警信号的情况下，设置灼伤标记，将预设的恢复机制NUC计时时间表中的第一个计时时长设定为预设恢复机制NUC计时时长。
当灼伤报警信号消除时，也就是，当挡片开启时，判断是否存在灼伤标记。若存在灼伤标记，则执行若当前挡片为开启，则启动恢复机制NUC计时。当恢复机制NUC计时的时长达到预设恢复机制NUC计时时长时执行NUC操作。
在恢复机制NUC计时的时长达到预设恢复机制NUC计时时长时执行NUC操作之后，判断当前的预设恢复机制NUC计时时长是否为预设的恢复机制NUC计时时间表中的最后一个计时时长。若是，消除灼伤标记；否则，继续检测是否生成灼伤报警信号。若检测到灼伤报警信号，也就是，在图像画面中仍然检测到高温对象，则会继续设置灼伤标记，将预设的恢复机制NUC计时时间表中的下一个计时时长设定为预设恢复机制NUC计时时长。
图3为本申请实施例提供的热成像摄像机灼伤防护方法的第一种流程图，其具体步骤如下：
步骤300：预先在热成像摄像机上配置灼伤防护检测周期，预先在热成像摄像机上配置防护模式选项：自动模式和手动模式。
挡片状态有两种：开启状态和关闭状态。当防护模式为手动模式时，挡片状态完全由用户决定和设定，即用户在热成像摄像机上设定挡片状态，热成像摄像机根据用户设定的挡片状态，对挡片执行开启或关闭操作。
步骤301：热成像摄像机在每个灼伤防护检测周期到来时，检测当前是否有灼伤报警信号，若是，执行步骤302；否则，执行步骤304。
当有高温物体进入热成像摄像机的采集范围后，热成像摄像机采集的图像画面的灰度会发生变化。本申请实施例中，可通过将图像画面的每一像素点的灰度与预设的灰度阈值进行比较，来决定是否产生灼伤报警信号。
步骤302：热成像摄像机判断当前防护模式为手动模式还是自动模式，若为手动模式，执行步骤306；若为自动模式，执行步骤303。
步骤303：热成像摄像机关闭挡片，初始化防护机制NUC计时时长为预设防护机制NUC计时时长，转至步骤306。
步骤303即为：热成像摄像机关闭挡片，并初始化防护机制NUC计时的时长，用于确定计时时长是否达到预设防护机制NUC计时时长。
步骤304：热成像摄像机判断当前防护模式为手动模式还是自动模式，若为手动模式，执行步骤306；若为自动模式，执行步骤305。
步骤305：热成像摄像机开启挡片。
步骤306：热成像摄像机判断当前挡片是否关闭，若是，执行步骤307；否则，返回步骤301。
步骤307：热成像摄像机启动关闭计时和防护机制NUC计时，当防护机制NUC计时的时长达到预设防护机制NUC计时时长时，开始执行NUC操作，当关闭计时达到预设关闭时长时，开启挡片，并将灼伤报警信号置0，返回步骤301。
上述将灼伤报警信号置0即为消除灼伤报警信号。
考虑到更改挡片状态的操作(即开启挡片或关闭挡片)是需要一定时间的，为避免在该操作时间内，对挡片实际状态的认定发生误判，本申请的一个实施例中，增加一挡片设定状态参数。且，当防护模式为手动模式时，该参数的值完全由用户设定。当防护模式为自动模式时，由热成像摄像机根据实际情况设定，具体地：
步骤303中，热成像摄像机先将挡片设定状态参数的取值置为：关闭值，然后执行关闭挡片的操作。
步骤305中，热成像摄像机先将挡片设定状态参数的取值置为：开启值，然后执行开启挡片的操作。
一个实施例中，在步骤305和步骤306之间增加一步骤3052：热成像摄像机判断当前挡片的实际状态与挡片设定状态是否一致，若是，直接执行步骤306；否则，根据挡片设定状态，对挡片执行对应的开启或关闭操作，以使 得挡片的实际状态与挡片设定状态一致，然后执行步骤306。
一个实施例中，步骤303具体可以为：热成像摄像机将挡片设定状态设置为关闭状态，关闭挡片，并初始化防护机制NUC计时的时长，转至步骤306。
步骤305具体可以为：热成像摄像机将挡片设定状态设置为开启状态，开启挡片。
另外，在步骤302和步骤304中确定当前防护模块为手动模式的情况下，或在步骤303中初始化防护机制NUC计时的时长之后，或在步骤305中开启挡片之后，热成像摄像机可以判断当前挡片的实际状态与挡片设定状态是否一致。若是，直接执行步骤306；否则，根据挡片设定状态，对挡片执行对应的开启或关闭操作，以使得挡片的实际状态与挡片设定状态一致，然后执行步骤306。
图3所示实施例适用于采用双置位挡片的热成像摄像机。因为：在控制单置位挡片关闭时，需要对挡片的控制线圈进行通电，但是长时间对控制线圈通电，会引起热成像摄像机内部的温度升高，导致测温不准确，影响此类热成像摄像机的核心功能。上述流程在产生灼伤报警信号时，要进行关闭挡片的操作，若长时间对控制线圈通电保持挡片的关闭状态，会导致测温不准确的问题，因此该实施例不适用于采用单置位挡片的热成像摄像机。
而对于采用双置位挡片的热成像摄像机，则不需要长时间对控制线圈通电，就可以控制挡片一直处于打开或者关闭的状态，不会因为一直对控制线圈通电导致热成像摄像机内部的温度升高，影响测温功能，因此，在检测到有高能量辐射物体进入画面后，通过上述实施例，可在不影响热成像摄像机的测温功能的情况下，实现对热成像摄像机的自动且不限温度范围的防灼伤处理。
通过上述实施例，当热成像摄像机处于自动防护模式下时，若检测到灼伤报警信号，即，检测到有辐射高能量的物体进入图像画面后，则关闭挡片，从而避免了图像传感器因直接面对辐射高能量的物体而造成永久灼伤的风险。另外，在保持关闭挡片过程中进行NUC操作，从而矫正临时灼伤产生的图像画面异常及测温不准确的问题，保证挡片再次开启时热成像摄像机的测温功能正常，保证了采集到的图像画面正常。
在热成像摄像机产生灼伤报警信号后，为了及时修复摄像机传感器的性能，本申请实施例给出如下的灼伤后恢复方案。
图4为本申请实施例提供的热成像摄像机灼伤后恢复方法的第二种流程图，其具体步骤如下：
步骤400：预先在热成像摄像机上配置灼伤恢复检测周期，并配置恢复机制NUC计时时间表，该时间表中包含多个顺序排列且依次增加的恢复机制NUC计时时长。
恢复机制NUC计时时间表中具体包含的恢复机制NUC计时时长的数目以及每个计时时长的取值，可根据热成像摄像机的图像传感器的材料特性决定。
对于恢复机制NUC计时时间表中的相邻两个计时时长，后一个计时时长总是大于前一个计时时长。图像传感器每进行一次恢复机制下的NUC过程，说明图像传感器材料已恢复过一段时间，且图像传感器材料恢复速度会随着恢复时间的延长而减慢。本申请实施例中，恢复机制NUC计时时间表中的计时时长按照依次增加的顺序排列，可以减少开、关挡片的次数，延长挡片使用寿命。
步骤401：当灼伤恢复检测周期到来时，热成像摄像机判断当前是否有灼伤报警信号，若是，执行步骤402；否则，执行步骤403。
灼伤恢复检测周期可设定为与灼伤防护检测周期相同。
根据步骤307，当挡片由关闭到开启时，会将灼伤报警信号置0。
步骤402：热成像摄像机将灼伤标记置1，并将预设恢复机制NUC计时时长设定为恢复机制NUC计时时间表中的第一个计时时长，返回步骤401。
这里，将灼伤标记置1即为设置灼伤标记。
步骤403：热成像摄像机判断灼伤标记是否为1，若是，执行步骤404；否则，返回步骤401。
步骤404：热成像摄像机判断当前挡片是否关闭，若是，返回步骤401；否则，执行步骤405。
本申请实施例中，对于采用单置位挡片的热成像摄像机，由于其挡片是开启的，因此，无需执行本步骤404，即，在步骤403中，判定灼伤标记为1时，直接执行步骤405。
步骤405：热成像摄像机启动恢复机制NUC计时，当恢复机制NUC计时的时长达到当前预设恢复机制NUC计时时长时，执行NUC操作。
步骤406：热成像摄像机判断当前预设恢复机制NUC计时时长是否为恢 复机制NUC计时时间表中的最后一个计时时长，若是，执行步骤408；否则，执行步骤407。
步骤407：热成像摄像机将预设恢复机制NUC计时时长设定为恢复机制NUC计时时间表中的下一个计时时长，返回步骤401。
步骤408：热成像摄像机将灼伤标记置0，返回步骤401。
灼伤标记置0表示本次灼伤恢复过程已完成。将灼伤标记置0即为清除灼伤标记。
图4所示实施例对采用双置位挡片和单置位挡片的热成像摄像机均适用。
通过上述实施例，在检测到有高温物体进入热成像摄像机的图像画面之后产生灼伤报警信号，并置位灼伤标记，并在高温物体离开画面之后执行NUC操作，从而修正图像传感器因材料特性发生改变，导致的图像画面异常及测温不准确的问题。
另外，考虑到图像传感器材料恢复速度会随着恢复时间的延长而减慢，从而设置了包含多个顺序排列且依次增加的计时时长的恢复机制NUC计时时间表，从而减少了开、关挡片的次数，延长了挡片使用寿命。
