In this research, six Energy Centre Localization Methods are assessed by Wilcoxon Signed Rank Test. Due to SHM is an upcoming tendency of determining the integrity of structures and development of strategies to prevent undesirable damage, it is necessary to detect a light emitter mounted on the structure under monitoring and calculate the energy centre localization. After a short introduction to the energy centre localization methods, a machine learning technique was applied to predict measurement errors and adjust non-linear variation for measurement accuracy improvement. An Optical Scanning System was enhanced by measurement at the optical signal energy centre and error adjustment by SVM algorithm. The theoretical methods principles, experimental development and validation are presented.

“…The environment conditions affect the measurements of the angles of each SA, the principal source of noise and the loss of resolution from the optical scanning system is the excessive bright of sunlight, as previously mentioned. In [ 9 , 17 ], is presented a complete description of the device system principle of operation. According to these works, the OSS generates a Gaussian signal, where the peak of this signal is related to the center of energy.…”

The present paper describes the experimentation in a controlled environment and a real environment using different photosensors, such as infrared light emitting diode (IRLED-as receiver), photodiode, light dependent resistor (LDR), and blue LED for the purpose of selecting those devices, which can be employed in adverse conditions, such as sunlight or artificial sources. The experiments that are described in this paper confirmed that the blue LED and phototransistor could be used as a photosensor of an Optical Scanning System (OSS), because they were less sensitive to sunlight radiation. Moreover, they are appropriate as reference sources that are selected for the experiment (blue LED flashlight and light bulb). The best experimental results that were obtained contained a digital filter that was applied to the output of the photosensor, which reduced the standard deviation for the best case for the phototransistor LED from 100.26 to 0.15. For the best case, using the blue LED, the standard deviation was reduced from 86.08 to 0.11. Using these types of devices the cost of the Optical Scanning System can be reduced and a considerable increase in resolution and accuracy.

“…Фотодиод регистрирует луч света, в то время как цилиндрический микростержень, закреплённый на штифте электромотора, работающего от постоянного напряжения, вращается. Данный элемент и генерирует сигнал, который анализируется рассматриваемыми методами [7,11,12]. Эти методы основаны на предположении, что сигнал ОСС, получаемый сканированием источника света, имеет форму гауссового распределения.…”
