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

Errors

Error type Description
DomainError Camera model in inTransform is not defined.
DomainError Homography matrix in inTransform is not defined.
DomainError Shifting world plane with non pinhole camera models (e.g. telecentric) is not supported yet.
