VEDDAC 7 is a universal and flexible DIC software for the analysis of motion, deformation and surface changes on the basis of digital image correlation.

Whatever image capturing technology you use, with VEDDAC 7 you can comfortably process even large image sequences.

This allows you to analyze your processes, even if the surface structure changes considerably during a deformation process. Surface preparation is usually not required for image evaluation with VEDDAC 7.

VEDDAC 7 features an innovative and intelligent patented analysis technology that provides demonstrably better evaluation quality, especially when the images to be analyzed show low contrasts or poor surface structuring.

This makes VEDDAC 7 the preferred evaluation tool for scanning electron microscope and X-ray computed tomography images.

VEDDAC 7 offers a variety of visualization features for displaying the results of your image sequence evaluation. You can display displacement fields, local strain fields, mean strains, bend lines, local velocities and accelerations or paths in VEDDAC 7 as a result image, video or diagram. With the new diagram function in VEDDAC 7 you can track your measured values in the diagram assigned to the result image. It is possible to import customer-specific data (e.g. force, temperature, ...) for display in the diagram.

Extensive export functionality allows you to use the results in external programs. The export is available as text/ Excel file, image sequence, data diagram or as video.

Use VEDDAC 7 in a wide variety of applications:

• Research and development
• Materials science
• Microelectronics
• Microsystems technology
• Automotive engineering
• Geosciences
• Mechanical and plant engineering
• Energy technology
• Construction and transport, and so on.

• High-precision subpixel algorithm: 10 times higher accuracy thanks to the new subpixel algorithm – even without sample preparation.
• Reduction of acquisition-related nonlinearities.
• Support for all common image formats and bit depths, including Bitmap, TIFF, JPEG, and PNG.
• 64-bit support: Enables the use of more than 2 GB of memory for managing large amounts of data.
• GPU hardware acceleration: The graphics card is used for correlation calculation and drawing operations. This results in increased performance when calculating and displaying images and effects.
• Intelligent area selection (Magic Shape Tool): Fast and easy selection of measurement point areas based on image content using an intelligent system.
• Integrated diagrams: Graphical presentation of data with an Excel "look and feel".
• Data export: Dynamic export of data in text or Excel format, creation of image sequences and videos for presentations.
• Export of calculation results for further processing in Python or other tools.
• Import of local user data (e.g. load or temperature values): User data can be used for false color representation. It is also possible to use the data in VEDDAC diagrams.

• Manually adjustable calculation mode: For each image pair, the calculation mode (Reference or Refresh) can be set manually.
• Filtering of measurement points: Measurement points can be filtered by region in the measurement point list.
• New image filter algorithm: This intelligent algorithm enables lossless filtering of image data.
• Extended correlation calculation: Revision of the subpixel algorithm for further reduction of "nonlinearities".
• Automated user actions: Configurable actions that are executed after the calculation is completed.

• Hardware-accelerated correlation: Correlation calculation is performed via the graphics card when possible. This makes the calculation speed many times higher than conventional CPU calculation.
• Improved median and Gaussian filtering: Reduction of edge effects.
• Improved outlier filter: The sensitivity of the filter no longer needs to be set.
• Parallel Line Shape: A shape tool for creating parallel lines.

• Import of VEDDAC strain templates (*.sdc files): VEDDAC strain templates can now be imported to enable exact comparison measurements between VEDDAC and VEDDAC strain.
• Intelligent area selection (Magic-Shape-Tool): Fast and easy selection of measurement point areas based on image content using an intelligent system.
• Dongle license system: Mobile license system for using VEDDAC on different PCs or laptops.

• Main strain directions: - Display of main strain directions as a vector gradient
• Template export for VEDDAC py: Templates can be saved to easily load and reuse sequence trees and measurement points in VEDDAC py.
• Import of local user data (e.g. temperature values): User data can be used for false color representation. It is also possible to use the data in VEDDAC diagrams.

The necessary system requirements depend largely on the number of images. For measurements with few images, as is typically the case with microscope images, SEM, AFM, etc., a current PC/Laptop without any special features is sufficient. For measurements with industrial cameras, where the number of images is high, a powerful PC is required. Detailed system requirements can be found in the following overview:

• Processor: Intel Core i5-4690 @3.5 GHz, AMD FX 6350 @3.9 GHz
• RAM: 8GB RAM
• Video card: DirectX 11 compatible GPU - NVIDIA GeForce GTX 970, AMD Radeon R9 290X, Intel UHD 750
• Operating system: Windows 10/11
• Hard drive: Sufficient storage for your images on SATA SSD
• Resolution: 1080p (Full-HD)

• Processor: Intel Core i5-10600 @4.1 GHz, AMD Ryzen 5 3600 @3.6 GHz
• RAM: 32GB RAM (depending on the number of measuring points)
• Video card: DirectX 11 compatible dedicated GPU - NVIDIA GeForce RTX 3060 Ti
• Operating system: Windows 10/11
• Hard drive: Sufficient storage for your images on NVMe M.2 SSD
• Resolution: 1440p (WQHD)
