Remarks

This property specifies the physical grid spacing in the y-dirrection.

For a checkerboard plate, this is the physical size of each tile, in the y-direction of raw calibrated space. If the plate has a fiducial mark, the y direction is parallel to the short fiducial rectangle. Otherwise, it is parallel to the rows of tiles closest to the y-axis of the pixel coordinate space.

The tiles in the physical calibration plate must all have exactly the same physical size in the y-direction. The images of the tiles in the acquired image may have different sizes.

For a grid-of-dots plate, this is the dot spacing, in the y-direction of raw calibrated space. If the plate has a fiducial mark, the y direction is the axis with a mark space at position 1. Otherwise, it is parallel to the rows of dots closest to the y-axis of the pixel coordinate space.

Note: You should specify this value in meaningful real-world units such as millimeters.

Default Value: 1.0
