摘要: A dynamic photometric stereo inspection technique usable to capture and analyse the topography of a moving surface. The includes an enhanced data method apparatus comprising spaced array at least two coplanar illuminates improve measurement range accuracy. can be used inspect banknotes, e.g. assist with fitness assessment and/or forgery detection. may comprise automatically assessing surface provide qualitative quantitative information about 2D 3D features, such as changes in reflectivity, colour, glossiness, texture profile under inspection.
