In Directed Energy Deposition, which is one of the metal additive manufacturing methods, it is important to monitor the temperature of entire layered objects. For temperature monitoring, a non-contact measurement using a thermal imaging camera is desirable. However, it is difficult to measure the temperature of layered objects having large fluctuations in emissivity. Therefore, a method was proposed for measuring the average temperature of square areas on the surface using a single emissivity. The measurement result shows that the surface temperature of layered objects can be measured with sufficient accuracy using appropriate square areas.
