Abstract

The temp. pattern measuring device is used for obtaining the surface temp. 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 colour temp. process for each minute area within a visual field of the image pickup, detecting the temp. at a portion on the surface of the corresponding measured object, thereby obtaining its temp. pattern. The above minute areas can be set by an electrical method using photoelectric conversion devices. Also a supervision unit for the weld zone at an electrically seamed pipe, may employ the temp. pattern measuring unit, the supervision unit producing a composite display of the form of the weld zone and its temp. pattern.
