The non-contact 3D sensing technology, though achieved many success in a variety of applications, needs an automation system to expand its applications to automotive industries for 3D shape inspection. The reason is the difficulty for an operator to find an optimal solution by the manual control of sensor viewpoints. The problem of this industrial application is the capability for the sensing system...
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...
Point cloud registration and sensor calibration are two critical technical issues concerning robot-mounted, area sensor systems. Iterative closest point (ICP)-based algorithms developed in the past are commonly used for point cloud registration. However, due to its least squared fitting nature, registration quality depends on how closely the measured part matches its nominal definition, typical in...
