Within the framework of the analysis of 3D textured surface through image analysis, we approach here the case of the 3D interfaces (fluid-solid) surfaces for the analysis of the local variations of their relief. Generally, the interaction between the light and these local variations of the relief leads to a textured images of these surfaces. Our aim here is to achieve the feasibility of this measurement through a local relief extraction based on photometric stereovision. The proposed approach is an original adaptation stereovision based on photometric model to the case of free surfaces with a high degree of variation and with Lambertian photometric behaviour .The suggested method is presented and the relevance of this approach for that kind of surface is tested on particular shape. The results obtained are the first step of a global study of the displacement of the local variation of this 3D free surface.
