An embodiment of the invention discloses a temperature calibration method and a temperature calibration device, which relate to the technical field of temperature measurement. The temperature calibration method comprises the steps of: carrying out preliminary calibration on each thermal imaging point on an infrared thermal imaging sensor by means of a first constant-temperature reference module arranged in front of the infrared thermal imaging sensor, so as to obtain preliminary calibration data of each thermal imaging point; performing secondary calibration on the infrared thermal imaging sensor by utilizing a second constant-temperature reference module arranged in a thermal imaging visible region of the infrared thermal imaging sensor during the period of measuring the temperature of ameasured object by utilizing the infrared thermal imaging sensor, so as to obtain secondary calibration data of the infrared thermal imaging sensor; and calibrating the temperature of the measured object by using the preliminary calibration data and the secondary calibration data, so as to obtain actual temperature data of the measured object. The temperature calibration method and the temperaturecalibration device can improve the precision of temperature calibration and temperature measurement by utilizing the first constant-temperature reference module and the second constant-temperature reference module.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of temperature measurement, in particular to a temperature calibration method and device. Background technique [0002] The sensors used in infrared temperature measurement technology are mainly divided into single-point infrared sensors and multi-point infrared thermal imaging sensors (hereinafter referred to as infrared thermal imaging or infrared thermal imaging sensors). Among them, in terms of human body temperature measurement, infrared single-point temperature measurement technology has been widely used. It can accurately measure human body temperature, but it has strict requirements on the measurement position. It is difficult to accurately measure the body temperature of moving objects. Infrared thermal imaging sensors are generally used in scenes that focus on the clarity of thermal imaging images and do not require high temperature accuracy, such as industry. Accurate tempe...
