“…The authors of [12] presented the results of damage detection and localization (notches, delaminations and drilling defects) in aircraft composite structures using the transient thermography approach. The latest studies of various thermographic techniques [13][14][15][16] show a great effectiveness and accuracy in detection and localization of low-velocity impact damage.…”

“…Several studies have shown good or even excellent results in using active thermography NDT capabilities applied to different composite materials configurations and defects typologies: delaminations [6,16], impact damage [17], adhesive and welded bond defects [2,18], reparation patches [3,19], fatigue damage [20],different nature inclusions [21], etc.…”

“…The use of inspection reference gauges or samples including known and controlled defects prove to be a key tool for defining inspection strategies, optimising parameters, and defects recognition, as well as for establishing the inherent limitations and sensitivity thresholds of the method [1,3,4,14,15,17,18,22,23].…”

Sintering is a complex industrial process that applies heat to fine particles of iron ore and other materials to produce sinter, a solidified porous material used in blast furnaces. The sintering process needs to be carefully adjusted, so that the combustion zone reaches the bottom of the material just before the discharge end. This is known as the burn-through point. Many different parameters need to be finely tuned, including the speed and the quantities of the materials mixed. However, in order to achieve good results, sintering control requires precise feedback to adjust these parameters. This work presents a sensor to monitor the sintering burn-through point based on infrared thermography. The proposed procedure is based on the acquisition of infrared images at the end of the sintering process. At this position, infrared images contain the cross-section temperatures of the mixture. The objective of this work is to process this information to extract relevant features about the sintering process. The proposed procedure is based on four steps: key frame detection, region of interest detection, segmentation and feature extraction. The results indicate that the proposed procedure is very robust and reliable, providing features that can be used effectively to control the sintering process.
