Surface inspection problems in thermoelectric testing

Visual inspection of a combustion process in a thermoelectric plant

Infrared images provide useful information to inspect the status of combustion processes. The flame geometry and intensity depend on the process variables and the characteristics of the combustion chamber. This paper describes methods to analyze infrared images of industrial flames and to characterize the flame geometry. A segmentation algorithm is proposed to separate the flame region from the...

Free-Form Surface Matching for Surface Inspection

Technology for Robotic Surface Inspection in Space

This paper presents on-going research in robotic inspection of space platforms. Three main areas of investigation are discussed: machine-vision inspection techniques, an integrated sensor end-e ector, and an orbital environment laboratory simulation. Machine-vision inspection utilizes automatic comparison of new and reference images to detect on-orbit induced damage such as micro-meteorite impa...

Content-based image retrieval in surface inspection

In this paper a prototype system is described for the management and content-based retrieval of defect images in huge image databases. This is a real problem in surface inspection applications, since modern inspection systems may produce up to thousands of defect images in a day. The retrieval is based on shape and internal structure characteristics of defects, so no manual labeling nor annotat...

Gipsy: Knowledge Based Surface Inspection

Despite of a great demand of automatic image analysis systems in the production industry, the spread of installed systems is still limited. Reasons for this are, among others, the high requirements of image analysis systems with respect to computational effort and accuracy, the high engineering effort for the development of image analysis applications, and thus high investment costs for image a...
