Abstract: The invention discloses an emissivity measurement method. The method comprises the processes of establishing an optimized emissivity measurement model, and measuring the emissivity of an object to be measured through using the optimized emissivity measurement model. The optimized emissivity measurement model establishing process concretely comprises the following steps: establishing an initial emissivity measurement model, selecting an object having a same material with the object to be measured as an experiment object, setting an emissivity estimation value epsilon'o, and calculating the set temperature T''obj of the experiment object; putting the experiment object in a blackbody furnace, setting the temperature of the blackbody furnace to be T''obj, and calculating the temperature Tobj of the experiment object in the blackbody furnace and the ambient temperature Tsur outside the blackbody furnace after stable reading; capturing heat radiation itot of the experiment body by using an infrared thermal imager; substituting the itot, the Tobj and the Tsur into the emissivity measurement model, calculating to obtain the emissivity epsilono of the experiment object, comparing the epsilono with the epsilon'o, and ending optimization if the epsilono is greater than the epsilon'o; and resetting the epsilon'o if the epsilono is smaller than the epsilon'o, and re-optimizing until the epsilono is greater than the epsilon'o. The method is simple and fast; and when the optimized emissivity measurement model is used to measure the emissivity of the object, the measurement result is accurate.
