The paper presents the work done by the authors in the area of thermal cameras evaluation. Image quality evaluation is an important factor when comparison between specific cameras are to be made. When addressing outdoor thermal cameras, the ambient temperature variation can be a problem for the image quality. The mathematical models were analyzed and many laboratory test were made in order to answer this question: up to what perspective is the focus shift affecting the image quality of a thermal vision system used in normal outdoor climatic conditions?.
