Wear Debris 3D Surface Shape Recovery Based on Shape from Shading

A shape from shading （SFS） algorithm used in the 3D recovery of wear debris is studied in this paper and the algorithm is applied in several typical ferrography images. The experimental results show that this algorithm is simple to implement,images recovered are stereoscopic,so it has a high value in engineering field. This method does not need expensive equipment and can supply the 3D information for the analysis of wear debris. Then more detailed surface information is extracted from the three-dimensional surface topography image and it has an important influence on the recognition of wear debris.
