Application of the morphological operations for defect area recognition using active thermography
نویسنده
چکیده
In paper some examples of the application of the morphological operations in defect detection, using an active infrared thermography are described. The fundamentals of the mathematical morphology and the two methods of the global thresholding are presented. These methods were used to the binarization of the analyzed thermal images. Further, the results of the background estimation, using an opening operation were presented. The estimation was performed for the thermal images of the defected material sample. The sample had a few defects with different depths. The experimental research were carried out using the thermal image sequence, recorded with the stepped heating method.

Numerical method of active thermography for the reconstruction of back wall geometry
The paper presents numerical methods to detect and classify defects and inhomogeneities by means of active thermography. The objective is to determine the wall thickness of structure elements with an inaccessible back wall, for example, of pipes or containers. As test specimens we used approximately 2 cm thick PVC samples with spatial variations in the back wall geometry. Flash lamps provided t...

متن کاملThermography detection of hidden defects
Thermography measurements allow to detect the defects that may appear undersurface of details with protecting covering. Subsurface defects in the sample have been detected using the high resolution thermal imaging camera FLIR SC7000. To introduce additional energy in a researched sample, a scanning hot air (about 110°C) nozzle is applied (a patent application P.403346). The hidden defect causes...
