Paper Abstract
Infrared thermography inspection is a full-field, non-contact method that allows the defects inside the materials to be detected at one time. However, an interface is required to transfer the gray-level represented infrared image into temperature field for further
evaluation. Based on the theory of radiation and the principle of infrared camera’s signal conversion, a method to convert the gray
level represented infrared thermal image into temperature field is developed. Test of the method on a cup of hot water was done. Thetemperature obtained by the proposed method and a commercial ones agree very well with each other. An average error less than 0.9% was achieved between them.
