Abstract

The invention provides a temperature extraction method and apparatus for an infrared thermal image. The method comprises the following steps: acquiring an infrared thermal image; performing interpolation processing on each pixel in the infrared thermal image according to the grey-scale maps of the infrared thermal image and a temperature wide bar thereof, and extracting the temperature value of each pixel of the infrared thermal image. The apparatus comprises an image acquisition unit for acquiring the infrared thermal image; a processing unit for performing interpolation processing on each pixel in the infrared thermal image according to the grey-scale maps of the infrared thermal image and the temperature wide bar thereof, and extracting the temperature value of each pixel of the infrared thermal image. The method and apparatus can obtain the temperature value of each pixel in the infrared thermal image so that the temperature data contained in the captured infrared thermal image can be acquired so as to facilitate the secondary analysis of the photographed infrared thermal image to find the failure of power equipment. Thus, the utilization rate of the infrared thermal image is improved.

Description

technical field [0001] The invention relates to the technical field of infrared temperature measurement, in particular to a temperature extraction method and device of an infrared thermal image. Background technique [0002] Objects in nature will emit rays as long as their temperature is higher than absolute zero. By detecting and collecting these rays, the required physical quantities, such as temperature measurement, can be obtained. Infrared temperature measurement technology is a technology that can quickly measure the surface temperature of objects. It has the advantages of fast temperature measurement speed, large temperature measurement area, high resolution, non-contact, and no interference with the surface temperature field of the measured object. It is widely used. in various fields. [0003] In the live detection of electrical equipment using infrared temperature measurement technology, a corresponding infrared thermal image can be obtained with a professional i...
