Imatest must know about the physical target being used in order to map image points to real-world spatial coordinates.
Supported values: Checkerboard
Note: Current the Geometric Calibrator only supports planar checkerboard targets, as described here. In the future, this list will grow.
Supported values: 3-Circle Type 1, 3-Circle Type 2
Each supported target type may have many variants.
For checkerboard targets, the supported variants are identified by their center-point defining fiducial pattern. (Checkerboards without one of these patterns are not supported in this module though may be used in Checkerboard module for other measurements).
Supported values: scalar value or two-element array
The actual size of the checkers of the physical target must be supplied. If the element size is supplied as a single value, it is assumed the checkers are square. If a two-element array is entered, the values indicate the x- and y-sizing, respectively.
Values must be accompanied by a dimensional unit indicating the SI unit sizes are defined in.
(Note: For high-precision use cases, measuring the non-squareness of your actual target is essentially, even of a nominally-square checkerboard.)
