Abstract
In this paper, various methods are proposed to correct distorted infrared images recorded over curved specimens. This problem is particularly important in thermal inspection applications, in order to avoid misinterpretation of the results. In the paper four methods are discussed: point source heating, video thermal stereovision, direct IR image calibration and shape from heating. Particular emphasis is given on the last two methods. Details of the methods are given and results presented for each method along with particular advantages and drawbacks.
