The objective of this paper is to propose a wind- shield surface shape and optical parameters inspection system. In this paper, a white board works as a diffuse planar light source projecting structured light patterns because physical properties of specular surface do not allow us to directly apply the triangulation-based techniques used in ordinary diffuse surface inspection. The board is placed...
In this paper we introduce a new point cloud registration strategy for 3D surface inspection, named object-oriented method. Traditionally, the registration methods use a fitting based algorithm, which is a recursive process and too time consuming to do quality inspection. Moreover, the fitting based algorithms require that the measured data and the CAD model have same shapes. Photogrammetry and ICP-based...
Accuracy is essential to surface quality control when a range sensor is applied to measure the 3D shape of an automotive body part. A sensor's viewing pose, including location and orientation, is related to measurement accuracy. It is usually difficult to find an optimal solution by manual control of sensor viewpoints. A CAD-guided robot view planner developed previously can automatically generate...
