Abstract
The commonly used method for surface roughness measurement in industrial applications is the direct method by using a measuring stylus [Lo et al. 2005]. Stylus techniques have great inherent limitations, such as the fragility of the instrument, the possible surface scratching, and the limited accuracy due to probe tip radius. In addition, only 2D surface topography is acquired with stylus techniques [Jetley et al. 1993].The development of non-contact based roughness measurement techniques for engineering surfaces has received considerable attention. The non-contact based roughness measurement techniques aim to find alternative ways to permit rapid surface roughness measurement with acceptable accuracy. One of the most promising non-contact based roughness measurement techniques is the computer vision technique [Li et al. 2004]. However, practical surface roughness measurement based on computer vision technology is still difficult [Lee and Tarng, 2001].
