ReferenceDiagonal¶

The diagonal size \(D\) of the view field of the camera which observed the pattern, at the distance of the pattern.

The diagonal of the view field can be used to judge the quality of the absolute error measures (TriangulationError), (RayDistanceError) and (PoseError).

EnsensoSDK tools require the calibration result to fulfill \(E_{pose} < 0.001 * D\) to judge the accuracy as good.
