这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
本发明实施例提供一种用于原木灭活仓的温度测绘系统，原木灭活仓采用微波介电加热方式对仓内待灭活原木进行灭活，待灭活原木采用单层平铺排列，相邻两根待灭活原木间隔为10cm左右，参见图1，每根待灭活原木被截为长度相等的4段，截断后的每根待灭活原木按照截断前的形状并拢还原放置；
该系统包括光纤温度传感器、温度校准标志物、红外成像测温装置和处理器；
其中，光纤温度传感器，置于待灭活原木内部，用于获取待灭活原木内部的第一温度值；参见图2，在使用光纤温度传感器测量原木内部温度时，待灭活原木转孔分别在边材(8)、芯材(9)、髓心(10)位置埋置光纤温度传感器，用于对待灭活原木内部不同部位温度的精确测量。
对典型原木根据端头量取边材、芯材、髓心不同深度，然后用转头根据不同深度分别打孔，埋入光纤温度传感器，用于测量边材、芯材、髓心位置处的原木温度；
红外成像测温装置，至少1个，分布安装在原木灭活仓内壁上，获取待灭活原木表面的第二温度值；在微波介电加热处理结束后，提起原木段，获取待灭活原木所有截面的第三温度值；
作为本实施例可选的一种实现方式，红外成像测温装置数量本发明实施例不做限定，可以由本领域技术人员根据实际工程需要，参见图3，如根据灭活仓尺寸选择，如可以为10个，在将红外成像测温装置安装在灭活仓时，每 个红外成像测温装置视场斜向下，相邻红外成像测温装置距离2m～2.5m之间，所有红外成像测温装置视场覆盖微波介电加热内待灭活原木全部上表面。
现有红外成像测温仪的测温方式存在测温精度不够高的问题，会导致测温偏差较大，为解决此问题，该系统还设有温度校准标志物，至少1个，固定在每路红外成像测温装置安装侧壁的对面侧壁视场内，被待灭活原木遮挡的未被微波覆盖的区域，温度校准标志物内壁固定热电偶，热电偶用于获取所述温度校准标志物所在位置的第四温度值；
作为本实施例一种可选的实现方式，温度校准标志物包括金属标志物和热电偶，金属标志物具有封闭的腔体结构，热电偶置于腔体内，热电偶测量的稳定数据供红外成像测温装置作温度校准。
处理器，用于获取第四温度值、第一温度值、第二温度值和第三温度值，通过第四温度值对第二温度值和第三温度值进行校准，对第四温度值、第一温度值、第二温度值和第三温度值进行视场校正和拼接，形成原木灭活仓内微波介电加热区域的温度分布图；
具体的，处理器通过第四温度值对第二温度值和第三温度值进行校准可以通过以下过程实现：
每路红外成像测温装置获取各自视场内温度校准标志物的灰度值；
根据多组灰度值数据和第四温度值获取灰度值与第四温度值的转换算法；
根据转换算法对各路红外成像测温装置所获得的第二温度值和第三温度值进行校准与转换得到标准温度值；
将原木表面区域的标准温度值叠加在全景图像对应位置上。
处理器对第四温度值、第一温度值、第二温度值和第三温度值进行视场校正和拼接可以通过以下过程实现：
以灭活仓内原木表面积的5％为单位监测区域，对原木表面作后处理区域划分；
提取每路红外成像测温装置所获取图像中的特征点，根据特征点的特性向量进行特征匹配，找到图像与图像之间的匹配点，其中特征点的选取由本领域技术人员结合现有技术实现，此处不再赘述；
根据匹配点计算图像变换矩阵，根据图像变换矩阵对每路成像测温装置所获取图像进行位置、角度、边界的确定；
根据各个图像的亮度对每个图像进行光照增益补偿，使每幅图像的亮度一致；
根据所述图像变换矩阵，通过图像融合方式把每路成像测温装置所获取图像拼接成一个无缝的全景图像。
红外成像测温仪的测温方式能够实现面测温，但在高强微波环境下，存在烧毁或干扰的问题，相关技术中已有一些防护手段，但已有防护手段通常会影响测试的准确性，为解决此问题，参见图1，每个红外成像测温装置包括截止波导保护套筒、红外测温热像仪、安装支架和空气输送管道；
参见图4，红外测温热像仪固定安置于截止波导保护套筒1内，截止波导保护套筒1用于衰减高强微波辐射能量，防止微波环境对红外测温仪进行干扰，影响测温精度和可靠性空气输入管道；镜头对准测温区域，用于测量物体实际温度；空气输送管道4一端延伸至红外测温热像仪镜头前，另一端延伸至原木灭活仓外面，原木灭活仓外面空气通过空气输送管道4被输送到红外测温热像仪镜头前，空气输送管道4将高湿环境外的低湿度空气持续输送到红外热像仪前端镜片上，防止高湿环境在热像仪表面形成水雾或水珠，影响测温精度；截止波导保护套筒外壁连接安装支架3；红外成像测温装置通过安装支架3固定在原木灭活仓内壁上，安装支架3与高强微波高温舱体内壁相连，用于固定整个红外成像测温装置。
可选的，截止波导保护套筒采用不锈钢或铝合金材质。
由于处理设施内部空间的限制，单一的红外成像测温仪的测温覆盖区域不足，且视场不同区域远近不同，成像存在畸变问题，本发明实施例采用10 路经过防护的红外成像测温装置5在灭活仓内左右两侧舱壁固定，间隔在2m～2.5m范围，红外成像测温装置5镜头视场斜向下，每路红外成像测温装置实现对其附近原木表面的2.5m纵向的视场覆盖，10路红外成像测温装置视场交叠实现对原木表面的视场覆盖；
