Temperature detection method based on infrared vision matching

The invention provides a temperature detection method based on infrared vision matching. The method comprises a template learning phase and a practical detection phase. In the template learning phase, an infrared vision image of a tested object is shot, and the infrared vision image and additional information are used as a tested object template, and the tested object template is stored; and in the practical detection phase, according to the additional information in the tested object template, an infrared vision image of the tested object is shot, whether the infrared vision image is matched with the tested object template is judged, and if yes, the current temperature field of the tested object is extracted from the infrared vision image. In power station unmanned operation and maintenance, an inspection robot is utilized to inspect in the power station for the all day, long-distance non-contact measurement of the temperature of the power station equipment is realized, and the temperature field of each part of objects is drawn.
