the automation of visual inspection for printed labels, which are coated with rubber and curl, we have developed a camera-based portable experimental device of automatic inspection in this research. By experiments, we have verified that the experimental device surely detect the failures such as the stain, the patchiness, the spread, and the chip detected by using low dimensional feature vectors...

This paper presents an automatic sensor placement technique for robot vision in inspection tasks. In such vision systems, a sensor often needs to be moved from one pose to another around the object to sample all features of interest. Multiple 3D images are taken from different vantage points. The technique involves deciding the optimal sensor placements and a shortest path through these viewpoi...

Automatic inspection of pipelines has great potential to increase the efficiency and objectivity of pipeline inspection. 3-D pipeline reconstruction can provide a valuable addition to automatic pipeline inspection. We present a system which can reconstruct the inner surface of buried pipelines from multiple fisheye images captured inside the pipes. The reconstruction output will facilitate pipe...

One of the most challenging scientific industrial problems in recent years is automatic defect detection and characterization. Automatic defect detection can replace human operators who locate and identify defects. Detection of defects in the steam generating tubes through periodic inservice inspection is one of the most significant issues of the fast breeder reactors. Among various pipeline in...
