Nowadays, with the evolution of new technologies, the use of 3D scanning systems is becoming more prevalent in the industry. These systems allow the acquisition of a large amount of data on the geometric representation of surfaces in a relatively short time. As the acquired data is usually exploited for many purposes such as reverse engineering or manufactured part inspection, the quality of point cloud or scanning quality has become a critical issue. The scanning noise is a common indicator to evaluate the scanning quality of the acquired data. In this paper, we propose a method to evaluate the scanning noise based on 3D mesh model. 3D point clouds obtained from the scanning system are aligned with 3Dmesh model of the scanned part and the noise is then calculated for each triangular facet. This noise is qualified in terms of quality by comparing with a threshold value of noise obtained from the sensor qualification protocol. |
