The basis for accurate multi-dimensional strain experiments is a precise calibration of the two (or more) cameras. LaVision employs a fully empirical calibration method, which does not involve measuring physical angles or distances. It has been proven to be highly accurate and reliable.
For the calibration of stereoscopic camera systems LaVision provides 3D Calibration Plates with defined separation of the calibration planes and mark spacing.
high precision dot pattern
two-level double-sided pattern suitable for simultaneous calibration from opposite sides
fiducials for automatic mark search identifying front and back side automatically
screw thread on border for easy mounting
The Single-sided Single Plane (SSSP) Calibration Plate is a widely used tool for calibrating 2D and 3D DIC setups. The calibration procedure when using this type of plate utilises several views of the plate at different positions and orientations within the depth of focus of the system. Marks are automatically detected, and all detected marks provide information which is used in the bundle adjustment calibration algorithm. During this live calibration procedure, the intrinsic and extrinsic camera parameters are calculated.
An additional feature of the plates are printed speckle patterns on the rear side, allowing the user to perform rigid body shift (0% strain) tests to quantify the uncertainty within the system.
suitable for calibration of 2D and 3D StrainMaster DIC systems
high precision dot pattern with three fiducials for orientation detection
lightweight and easy to handle
plates are provided with printed speckle pattern on the back side for 0 strain test according to VDI standard 2626
These Micro Calibration Plates can be used for calibration purposes for μDIC StrainMaster systems with small scale fields of views (FoV).
There are various types of plates available with several targets of different dot diameters and distances.
