Abstract : The purpose of this study is to characterize the influence of environmental parameters for long-term in-situ structure monitoring as well as projections errors due to camera view and digitization. Measurements made on an instrumented test site have been made during the last 3 years, bringing an interesting dataset to exploit. The model used to convert the gathered data to temperature is firstly presented and discussed. Then, the effect of camera resectioning on infrared measurements is commented. Finally, the effect of the environmental parameters is studied and perspectives are proposed.
