Title:
COMPONENT INSPECTION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/238465
Kind Code:
A1
Abstract:
In order to inspect a minimum distance between an ignition coil (3) and a fuel tube (4), the present invention involves: generating point cloud data through scanning by a three-dimensional laser scanner (5) (S1); and positioning reference point cloud data based on CAD data (S4-S14). After the positioning, the measured point cloud data is interpolated using the reference point cloud data (S17), and a minimum distance between given two points is calculated (S19). When the reliability level is low (S15, S16), a loss region is determined (S17) and additional scanning is performed. In this case, a multitude of virtual viewpoints that are set around the region are assessed and measurement parameters for a trajectory and the like are calculated so as to connect advantageous points (S23), and an instruction for additional scanning along the trajectory is given (S24).
