“…Contact measurements provide good presentation of surface morphology, but the time needed to gather data is much longer than that required by the contactless methods [25]. Contactless methods are optical methods, which can themselves be divided into the optical confocal method, interferometry, scatterometry, triangulation, and the structured light method [26][27][28][29]. The confocal method assembles a spatial surface image from planes on which light successively focuses during the measurement process.…”

This paper compares methods for measuring selected morphological features on the surface of thin metallic layers applied to flexible textile substrates. The methods were tested on a silver layer with a thickness of several hundred nanometers, which was applied to a textile composite with the trade name Cordura. Measurements were carried out at the micro scale using both optical coherent tomography (OCT) and the traditional contact method of using a profilometer. Measurements at the micro-scale proved the superiority of the OCT method over the contact method. The method of contactless measurement employs a dedicated algorithm for three-dimensional surface image analysis and does not affect the delicate surface structure of the measured layer in any way. Assessment of the surface profile of textile substrates and the thin films created on them, is important when estimating the contact angle, wetting behavior, or mechanical durability of the created metallic structure that can be used as the electrodes or elements of wearable electronics or textronics systems.

“…Based on the surface characteristics of the object, the non-contact three-dimensional surface imaging techniques could be divided into two categories: techniques to measure the specular surfaces [1][2][3][4][5] and techniques to measure the diffuse surfaces [6][7][8][9][10][11][12][13][14][15][16][17][18] . No matter for the specular surfaces or the diffuse surfaces, the robust measurement with one-shot is very challenging, however, it is highly desired especially when the measured surfaces are dynamic and deformable.…”

“…No matter for the specular surfaces or the diffuse surfaces, the robust measurement with one-shot is very challenging, however, it is highly desired especially when the measured surfaces are dynamic and deformable. As a result, many one-shot methods have been proposed for specular surface measurement [1][2][3][4][5] and diffuse surface measurement [11][12][13][14][15][16][17][18] . Each proposed method has its own merits or limitations and its application is also limited.…”

“…Existing measurement methods of parts can be divided into contact and noncontact. The noncontact measurement method is extensively used in the mechanical industry given the protection of an objective surface, high measurement accuracy, and large measurement range [5,6]. Noncontact measurement in reverse engineering mainly focuses on 2D image processing [7,8] and 3D scanning data processing [9][10][11].…”

The reconstruction of the profile curve of damaged parts in the absence of an original technical drawing is an important process of part repair. Part damages are complicated and changeable. To reduce the material removal rate during repair and maintain a smooth and flawless profile curve after being repaired, a smoothing and reconstruction strategy using a laser displacement sensor to measure the profile curve was proposed in this study. This strategy established an adaptive measurement mechanism by building an automatic measurement motion platform. A staged repair and smoothing strategy of the profile curve measurement data was constructed on the basis of the locally weighted scatterplot smooth. A calculation model of a part repair processing curve was built by using the Akima interpolation. Moreover, a case study was conducted to verify the reconstruction accuracy of the strategy and smoothness of the reconstruction curve. Results demonstrate that the automatic measurement motion platform and adaptive measurement mechanism can realize an adaptive measurement of different profile structural shapes. The staged repair and smoothing strategy can repair the measurement error of profile curve measurement data, profile defects, and other abnormal data while maintaining the smoothness of the profile curve. After repair, the variation range in the measurement data error at different points of the profile curve decrease from (−1.4913, +0.0351) to (−0.3511, +0.3715). Akima interpolation can not only increase the maximum error of the processing curve but also decrease the material removal rate effectively and protect the smoothness of the profile curve. This study provides important guidance to increase the part repair efficiency and accuracy and realize the automatization of part repair.
