FilterGridPoints

Expert

Module: Calibration

Select a subset of the given points that forms a grid.

Name Type Range Description
Input value inPoints Point2DArray
Input value inMaxAttempts Integer* 1 - Maximum number of attempts at finding the grid
Input value inMaxOutlierCount Integer* 0 - Determines how many outlier points can be present to end the search
Input value inMinLength Real 0.0 - Minimum length of a grid segment
Input value inMaxLength Real* 0.0 - Maximum length of a grid segment, if set to Auto it will be approximated
Input value inMaxLengthRatio Real 1.0 - 2.0 Maximum ratio of two consecutive segments in the grid
Input value inAngleRange Real 0.0 - 45.0 Maximum variation of angles between neighbouring grid segments in degrees
Input value inBaseAspectRatioRange Real 0.0 - 1.0 Maximum variation of the base aspect ratio (ignores if base aspect ratio is not given)
Input value inBaseAspectRatio Real* 0.3 - 1.0 A reference aspect ratio of the grid
Input value inBaseShear Real* 0.0 - 60.0 A reference shear angle between grid directions that uses inMaxAngleRange as the maximum error range
Input value inBaseOrientation Real* 0.0 - 360.0 A reference orientation of one of the grids directions
Output value outPointGrid Point2DArray Detected grid
Diagnostic input diagValidSubgraph Segment2DArray Graph forming a valid grid
Diagnostic input diagMaxLength Real Max length computed by the filter (applicable if inMaxLength is set to Auto)
