— Introduction to the Revealer RVM Digital Image Correlation System
In the fields of material testing and structural testing, Digital Image Correlation (DIC) has become a widely adopted non-contact technique for full-field displacement and strain measurement. As experimental scenarios increasingly involve dynamic loading conditions such as impact, vibration, and fatigue, conventional offline DIC workflows show limitations in real-time feedback and engineering applicability.
To address these challenges, Agile Device has developed a new-generation Revealer Digital Image Correlation (DIC) software, RVM. Through a system-level redesign of computational architecture, algorithmic workflow, and user interaction, RVM enables real-time DIC measurement tailored for engineering and research applications.
Traditional DIC software typically relies on an offline “acquire-then-process” workflow, where experimental parameters and analysis results can only be validated after data acquisition, limiting in-situ experimental control.
The Revealer RVM Digital Image Correlation (DIC) software introduces high-order image interpolation algorithms and a high-performance parallel computing framework, enabling real-time full-field DIC analysis, including:
Real-time full-field displacement and strain computation
Real-time video extensometry
Real-time feature point and marker tracking
Under a resolution of 4096 × 3000 pixels, RVM supports real-time computation of over 10,000 measurement points, achieving strain calculation rates of up to 20 fps. This capability allows researchers to observe strain localization and crack initiation during dynamic experiments, reducing information loss associated with offline processing.
In tensile and large-deformation tests, contact extensometers often suffer from installation complexity and detachment risks. The Revealer RVM DIC software implements a real-time video extensometer based on sub-pixel feature tracking and dynamic gauge length compensation.
This function provides real-time output of axial strain, transverse strain, and Poisson’s ratio at frame rates of several hundred frames per second, making it suitable for elastomers, rubber, composite materials, and fiber-based specimens.
Calibration accuracy is critical to the reliability of Digital Image Correlation measurements. Conventional DIC systems require substantial user expertise to ensure appropriate calibration quality.
The Revealer RVM Digital Image Correlation software incorporates an intelligent calibration mechanism through coordinated hardware and software design. The system automatically evaluates calibration board pose and coverage during acquisition and provides real-time adjustment guidance, improving calibration consistency in both laboratory and field environments.
At the software architecture level, RVM redesigns the traditional DIC workflow to enhance continuity and usability:
Guided project configuration
Real-time visualization of raw images, strain maps, and extensometer curves
Embedded operational guidance
Multi-format data export compatible with MATLAB and Python
Furthermore, the Revealer RVM Digital Image Correlation (DIC) software provides standard communication interfaces and SDKs, enabling integration with infrared cameras, testing machines, and other sensors for multimodal measurement systems.
The Revealer RVM Digital Image Correlation (DIC) software represents a transition of DIC technology from a precision-focused analysis tool to a real-time, intelligent engineering measurement platform. Its system-level innovations in real-time computation, intelligent calibration, and workflow optimization offer an efficient and reliable solution for material mechanics research, structural health monitoring, and industrial inspection.
