Colour digital image correlation method for monitoring of cultural heritage objects with natural texture

Read Abstract +

Digital image correlation (DIC) is a well-established technique for the measurement and monitoring of displacements and strains in engineering objects. In technical applications, an object's surface is modified by applying random, artificial structure, and monochrome cameras are typically used. The challenge in the measurement of Cultural Heritage objects (CHO) lies in the necessity of using the natural surface texture (no modifications are allowed), which in most of the cases is far from the ideal random pattern required for the successful implementation of DIC. On the other hand, spectrally separated content of natural CHO textures may provide additional spatial information and support DIC analysis. In this work, we propose a colour image pre-processing path that provides the input data best fitted to high accuracy 2D DIC and 3D DIC analysis. For this task we employ cameras with a colour filter array (CFA) with a Bayer pattern. This pattern has twice the number of green photosites as red or blue arranged in a 2x2pixel repeating-unit. From this sparse colour sampling, a full colour image is produced by interpolating the unknown values in each color channel. The interpolation is achieved via any one of the many demosaicing algorithms available to calculate a red, green, and blue value for every pixel position that only data from one channel was captured. These three R, G, B channels can then be combined to create a monochrome image suitable for conventional DIC analysis. This work's main objective is to select the best demosaicing algorithms for the spectral and monochromatic channels to minimize displacement and strain reconstruction errors (STD and P/V). The systematic analysis will be performed for objects (mock-ups) with artificial texture and fully controlled displacements. The expected errors due to interpolation procedures will be identified. Next, the best demosaicing procedure will be implemented into the full processing path of colour DIC used for selected CHO with natural texture (parchments, oil paintings). The analysis results based on monochrome, spectral, and mixed spectral data channels will be compared from the point of view of their applicability to different types of natural texture and achieved measurement accuracy.

Conventional (analog) holographic interferometry (HI) has been used as a powerful technique in optical metrology since sixties of XX century. However, its practical applications have been constrained because of the cumbersome procedures required for holographic material development. Digital holography has brought significant simplifications due to digital capture of holograms and their further numerical reconstruction and manipulation of reconstructed phases and amplitudes. These features are the fundamentals of double exposure digital holographic interferometry which nowadays is used in such applications as industrial inspection, medical imaging, microscopy and metrology. However another very popular HI technique, namely real time holographic interferometry has not been demonstrated in its digital version. In this paper we propose the experimental-numerical method which allows for real-time DHI implementation. In the first stage a set of digital phase shifted holograms of an object in an initial condition is captured and the phase of an object wavefront in the hologram plane is calculated. This phase is used to address a spatial light modulator, which generates the initial object wavefront. This wavefront (after proper SLM calibration) propagates toward an object and interfere with an actual object wavefront giving real-time interference fringes. The procedure works correctly in the case when CCD camera and SLM LCOS pixel sizes are the same. Usually it is not the case. Therefore we had proposed two different methods which allow the overcome of this mismatch pixel problem. The first one compensates for lateral magnification and the second one is based on re-sampling of a captured phase. The methods are compared through numerical simulations and with experimental data. Finally, the implications of setting up the experiment with the object reference phase compensated by the two approaches are analyzed and the changes in an object are monitored in real time by DHI.

The measurement and characterization of micro-optical elements, systems and materials related to a variety of aspects like shape, displacement, deformation, strain / stresses, material constants, chemical composition etc. is a huge area which requires extended, multidisciplinary knowledge and a wide range of expensive instrumentation. The NEMO Centre for Measurement and Instrumentation includes twenty four institutes, whose joint expertise and capabilities do not only cover nearly all important measurement and characterization methods; they also comprise a big pool of commercial and internally developed instrumentation. In this paper we present the main tasks of this Centre. These tasks consist in e.g. providing benchmarks of the instrumentation and analysis software, providing an integrated pool of equipment for measurement and characterization of materials and components, identifying the gaps in measurement capabilities of existing equipment and providing guidance for development of new measurement methods and instrumentation, the development of proof-of principle demonstrators of novel measurement systems, and the development of numerical-experimental methods in collaboration with the virtual Centre for Modeling to support the development of novel micro-optics. In this paper we will also review the expertise of the NEMO partners in micro-optics measurement and characterization with the emphasis on aspects such as: microlens array testing, waveguide and fibre optics characterization, measurement of static and active microelements, determination of 3D refractive index distribution, subwavelength structure characterization, and shape monitoring and strain distribution testing in micro-optic packages. Also interesting issues connected with the definition of optimised measurement chains, data analysis and standardization of measurement procedures will be touched upon. Finally we will discuss the future structure of the Centre and its potential to provide virtual or on-site access to an electronic library which already contains a considerable amount of information on the large pool of instrumentation, jointly provided by the NEMO's partners.
