Quality inspection is an indispensable part of modern industrial manufacturing. Steel as a major industry requires constant surveillance and supervision through its various stages of production. Continuous casting is a critical step in the steel manufacturing process in which molten steel is solidified into a semi-finished product called slab. Once the slab is released from the casting unit, th...

In this paper, we describe NASA Ames Research Center's K10 rover as used in the 2006 Coordinated Field Demonstration at Meteor Crater, Arizona. We briefly discuss the control software architecture and describe a high dynamic range imaging system and panoramic display system used for the remote inspection of an EVA crew vehicle.

This paper presents a novel approach of visual inspection for texture surface defects. It is based on the measure of texture energy acquired by a kind if high performance 2D detection mask, which is learned by genetic algorithms. Experimental results of texture defect inspection on textile images are presented to illustrate the merit and feasibility of the proposed method.

Specular surfaces inspection is a problem met frequently within the automatic control of metallic products. A tried technique to reveal the aspect defects is the imaging of the reflection of a structured lighting as Dark Field Illumination through the surface. In order to inspect the whole surface, an element of the lighting structure has to scan every part of the surface. In the case of import...

this paper presents a new methodology for the automated inspection of pipes. standard inspection systems are based on closed-circuit television cameras which are mounted on remotely controlled robots and connected to remote video recording devices. the main problems of such camera-based inspection systems are: 1) the lack of visibility in the interior of the pipes and 2) the poor quality of the...

Visual inspection of material’s surface quality is an important quality determining step in industries dealing with surfaces as the prime feature of their product, for instance, plywood, metal, tiles, glass ware and many more. Primarily surfaces are inspected for smoothness and roughness quality. However, defects may arise in form of cracks, spots, holes, presence of excess material, flatness a...

Rail surface inspection using a visual system is an important task in the maintenance of railway networks. Recent approaches have attempted to harness low-level features identify defects. These methods' main issues are limitations and prior information about rail surfaces that show wide variety appearances on dynamic backgrounds. To overcome these problems, we propose deep extractor (DE) combin...

CONVENTIONAL SURFACE INSPECTION We have developed a new apparatus to cope W I T H LASER BEAM. with the surface inspection of products having even undulating or stepped surfaces. To realize such surface inspection, we combined the three dimensi~nal shape measurement through laser beam scanning and the flaw and defwct identification t h m u g h diffraction light pattern analysis. This combination...
