Assessment of the Surface Roughness of Metal Mechanical Parts by Microsoft Kinect V2

Abstract

In mechanical manufacturing, the surface roughness of a machined part is a significant parameter to evaluate the products’ quality, and as a result, it must be thoroughly measured. Many researches have been studied over the past few to reduce the inherent drawbacks, such as contact, off-line inspection, speed of limited measurement, in the conventional measurement system using contact method. In this paper, the feasibility of the contactless inspection of part surface roughness using Microsoft Kinect v2 have been demonstrated. The part roughness parameters have been estimated by using of PCA plane fitting on point cloud data. In addition, the results received with the Microsoft Kinect v2 system are finally compared to those received with a stylus contact surface roughness measurement system to verify the proposed approach within this paper.
