Converting the infrared thermal image into temperature field for detection the defects inside materials

摘要：

　　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.The temperature 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.
