Abstract
In this paper, a new method for multi-resolution characterization is introduced to analyze porous surfaces on cylinder liners. The main purpose of this new approach is to investigate the influence of resolution and magnification of different optical lenses on measuring the 3D geometry of pores based on 3D microscopy topographical surface metrology. Two optical sensors (20× lens and 50× lens) have been applied to acquire the porous surface data for the primal investigation. A feature-based image matching algorithm is introduced for the purpose of registering identical microstructures in different datasets with different pixel resolutions. The correlation between the sensor's resolution and the numerical parameters' values regarding the pores geometry is studied statistically. Finally, the preliminary results of multi-resolution characterization are presented and the impact of using a sensor with higher resolution on measuring the same object is discussed.
