ShiftWorldPlane


Module: Calibration

Shifts world plane along its normal vector.

Applications

Correction of already calibrated world plane. Useful for avoiding recalibration when, for example, the product thickness on a conveyor belt changes by a known amount.
Name Type Description
Input value inTransform RectificationTransform
Input value inDeltaZ Double The world plane will be shifted by given amount in direction perpendicular to the grid. Positive translations move plane away from camera.
Output value outTransform RectificationTransform

Examples

Description of usage of this filter can be found in examples and tutorial: Calibration World Coordinates On Original Images.
