FlexDIC

FlexDIC system used to measure Lg. Principle Strain 1 (Major Strain) of an Alu. Coupon in a quasi-static tensile test with analogue input (from load cell)
 

The FlexDIC is a Digital Image Correlation (DIC) measurement system designed as a flexible, robust and multi-functional industrial & academic utility for a wide range of materials testing & motion analysis applications.
This easy-to-use system can perform all your testing needs allowing any user to quickly perform accurate & precise measurements for displacement, contour (shape), strain, and (discrete) kinematic quantities of tracked points. The FlexDIC is completely modular and can be upgraded with additional lenses, calibration targets, illumination systems, and also with additional cameras turning the system into a MulticamDIC system.

This easy-to-use system can perform all your testing needs allowing any user to quickly perform accurate & precise measurements for displacement, contour (shape), strain, and (discrete) kinematic quantities of tracked points.
Possible material testing & motion analysis applications include; simple, quasi-static tension, compression, buckling, 3- and 4-point bending, shear, low cycle fatigue (LCF), and fracture mechanic testing.

When a CRCP is directed onto a 2-camera FoV, the outer camera FoVs can in turn be split & segmented with the FoV provided by the CRCP. This in turn increases the FoV of the measurement system, whilst retaining the spatial accuracy provided by the image scale as determined by the outer cameras.
This allows for improved surface coverage on test specimens that are curved, cylindrical, or have uneven surface shapes and is particularly useful for the measurement of corners or edges with small radii.

The FlexDIC is a complete & fully equipped system, supplied (as standard) with one Laptop PC, one DAQ Controller, lenses, calibration targets, mounting, and a tripod. The measurement performance is harnessed using either; 1x, 2x, or 3x CMOS cameras with USB3 or GiGE vision technology. (A standard FlexDIC system consists of a 3-camera system).
The system can be operated in either; DAQ Triggered or Master/Slave mode. Using the DAQ Controller, the FlexDIC can read in up to 8x +/-10V analogue signals (i.e. for a load cell or LVDT). It also allows up to 2 analogue outputs to be read-out from Istra4D (requiring the DSM 32015: Istra4D Real-Time Correlation Evaluation Module).

Since 3D information can only be calculated from objects that are imaged by at least 2 cameras, the Field-of-View (FoV) is limited to the overlap between each camera-pair FoVs. Achieving an overlap can be difficult, partially, due to the stereo-angle tradeoff, but also for the measurement of an object that is non-planar or curved. The solution to overcoming this restriction is to use an additional perspective provided by a 3rd central camera positioned between the two outer cameras.
The central camera is then assigned as the “reference” camera. This approach is known as the “Central Reference Camera Perspective (CRCP)”.
