3D Calibration Plates

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 two-level 3D calibration plates with defined separation of the calibration planes and mark spacing.

In contrast to widely used single-level calibration targets movement of the plate through the volume or taking several views is typically not required. In the most cases taking a single image from the 0-plane position of the specimen is sufficient to calibrate the entire volume.
