    • A temperature pattern measuring device for obtaining the surface temperature distribution of an object. The device receives an image of the measured object and two different wavelength components of light emitted from the object. The device performs a two color temperature process for each minute area within a visual field of the image pickup, detecting the temperature at a portion on the surface of the corresponding measured object, thereby obtaining the temperature pattern thereof. The above minute areas can be set by an electrical method using photoelectric conversion means. Also, a supervision unit for the weld zone at an electrically seamed pipe, may employ the temperature pattern measuring unit of the present invention, the supervision unit producing a composite display of the form of the weld zone and the temperature pattern thereof.
    • 一种用于获得物体的表面温度分布的温度图案测量装置。 该装置接收被测物体的图像和从对象发射的光的两个不同波长分量。 该装置对图像拾取的视野内的每个微小区域进行双色温度处理,检测相应测量对象的表面上的一部分的温度,从而获得其温度图案。 可以通过使用光电转换装置的电气方法来设定上述微小区域。 此外,在电接缝管上的焊接区域的监督单元可以采用本发明的温度模式测量单元,监督单元产生焊接区形式的复合显示器及其温度图案。
