In the era of Industry 4.0, manufacturing is shifting from mass production to high-mix, low-volume, and lean manufacturing models. At the Industrial Innovation Forum, Lu Gang, Deputy General Manager of XTOP3D, highlighted that while this flexibility helps manufacturers adapt to volatile markets, it introduces severe challenges for shop-floor scheduling, efficiency, and quality control. Traditional spot-checking methods are no longer sufficient to guarantee precision. Consequently, comprehensive and in-line 3D inspection has emerged as the mandatory new standard. XTOP3D addresses these modern manufacturing demands with its advanced, non-contact 3D optical metrology, digital image correlation (DIC), and automated scanning systems, enabling seamless smart inspection and ensuring robust quality assurance across complex production lines.

Developed by XTOP3D, the DIC-3D non-contact 3D optical strain measurement system utilizes digital image correlation (DIC) technology to deliver advanced full-field deformation and strain analysis. Operating without physical contact, the system supports both online and offline real-time calculations, bypassing the need for traditional strain gauges. It adapts to various material types and testing rates under static or dynamic conditions. The system is widely applied in materials research (e.g., tensile, bending, and fatigue testing), operational component analysis (twisting, displacement, and vibration), and finite element analysis (FEA) simulation validation. By comparing empirical measurement data with theoretical models, XTOP3D helps manufacturers optimize product design, improve simulations, and accelerate time-to-market.

This article highlights the key advantages of XTOP3D’s non-contact strain measurement software powered by Digital Image Correlation (DIC) technology. The XTDIC software platform offers six core capabilities: complete data traceability, flexible data acquisition control, and seamless synchronized measurement using multi-camera groups (1–8 cameras). Additionally, it delivers advanced digital image detection for 3D full-field dynamic data (including displacement, velocity, and temperature fields), robust 6-DOF rigid body motion analysis, and comprehensive strain calculations featuring 18 advanced algorithms for static, dynamic fracture, and fatigue testing.

This article provides a comprehensive overview of Digital Image Correlation (DIC) technology, an optical, non-contact method used for measuring material mechanical strain and deformation. By tracking the gray-level variations of speckle patterns on an object's surface during deformation, DIC delivers accurate 2D and 3D full-field strain data. Developed by the expert research team from Xi'an Jiaotong University, XTOP3D’s advanced XTDIC system represents top-tier independent intellectual property in China. Transitioning from its legacy XJTUDIC system, the modern XTDIC 3D full-field strain measurement system delivers highly customizable, industry-specific measurement solutions for global clients in aerospace, materials testing, and automotive industries.
