Abstract: A high-precision non-contact temperature measurement device includes: a thermal insulation box made of a thermal insulation material and having therein a receiving space; a dynamic constant-temperature feedback control module for controlling temperature of the receiving space; and a non-temperature-sensing thermal imager disposed in the receiving space. The device achieves system thermal insulation within a non-contact temperature measurement gauge, maintains the overall closed system dynamically at constant temperature, compensates for effects of internal chip self-heating effect and visual field background temperature variation, and finally calculates average temperature of surfaces of a target precisely with an imaging, non-contact temperature measurement gauge and a temperature calibration algorithm widely used in thermal-imaging non-contact temperature measurement.
