Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Most existing successful photometric stereo setups require large angular variations in illumination directions, which results in acquisition rigs that have large spatial extent. For many applications, especially involving mobile devices, it is important that the device be spatially compact. This naturally implies smaller angular variations in the illumination directions.  studies the effect of small angular variations in illumination directions to photometric stereo.  explore both theoretical justification and practical issues in the design of a compact and portable photometric stereo device on which a camera is surrounded by a ring of point light sources.  first derive the relationship beten the estimation error of surface normal and the baseline of the point light sources. Armed with this theoretical insight,  develop a small baseline photometric stereo prototype to experimentally examine the theory and its practicality.
