Opis:: This work presents the method of leaks detection in recorded sequence of infrared images. Infrared field measurements were taken on small experimental embankment during flood process simulation. The leak processes took place thru initially dry facility. Getting wet areas were visible in infrared images as lower temperatures part of embankment on its air side. Image processing methods allowed to localize the leak in thermal images, despite the impact of external factors on the measurement and differences in objects emissivity in the observed scene.

Opis:: Industrial pipelines are used as a low-cost method of transport of various types of substances. In the last decades the number of transmission and distribution pipelines increased considerably, leading to an increased number of failures and rising the need for better and more accurate non-destructive methods of their detection and prevention. Leakage in pipeline networks causes a loss of valuable resources in the form of oil and gas. Repairing the infrastructure requires significant additional financial resources. Therefore, any damage to the pipeline network must be detected and repaired as soon as possible. Indirect methods for leak detection and localization uncover the presents of leaks from outside the pipeline by visual observation or by using appropriate equipment. Pipelines are often underground installations or run for many kilometers in areas where there are no roads, and access is extremely difficult or impossible. The underground occurrence of pipelines makes regular inspection difficult. It is also not possible to examine all pipeline sections simultaneously. Pipeline preventive maintenance or replacement program should be conducted based on detailed assessment of its technical and environmental conditions. Thus, safe and non-destructive techniques are needed, which would allow for pipeline periodical inspection without disturbing their operation.
