Camera Calibration

Select a function from the list below.

IconNameDescription
AnnotateGridPointsSelect a subset of the given points that forms a grid and assign 2D indices to them.
CalibrateCamera_PinholeFinds the camera intrinsic parameters from the input arrays of annotated image coordinates. Uses pinhole camera model (perspective camera).
CalibrateCamera_TelecentricFinds the telecentric camera intrinsic parameters from the input arrays of annotated image coordinates.
CalibrateWorldPlane_DefaultFinds the image to world plane transformation matrix. World plane origin and axes are unspecified. Useful for image rectification or distance measurements.
CalibrateWorldPlane_LabeledFinds the image to world plane transformation matrix using sparse world coordinate information, i.e. world coordinates are known for only a few points of the grid.
CalibrateWorldPlane_ManualFinds the image to world plane transformation matrix. Image and their corresponding world points are directly specified (no grid needed).
CalibrateWorldPlane_MultigridFinds the image to world plane transformation matrix using multiple grids, using sparse world coordinate information.
CalibrateWorldPlane_OffgridOriginFinds the image to world plane transformation matrix, with world origin and axes specified in the image coordinates. Note that this is a filter for rather rarely seen special cases and it is usually better to use the CalibrateWorldPlane_Labeled filter.
CreateRectificationMap_AdvancedComputes a spatial map for transforming distorted images to rectified images defined in world coordinate plane. Allows for flexible definition of output geometry.
CreateRectificationMap_PixelUnitsComputes a spatial map for transforming distorted images to rectified images defined in world coordinate plane. Defines the output geometry in pixels.
CreateRectificationMap_WorldUnitsComputes a spatial map for transforming distorted images to rectified images defined in world coordinate plane. Defines the output geometry in world units.
DetectCalibrationGrid_ChessboardDetects a chessboard calibration grid on the image, and returns calibration points where 4 chessboard squares meet.
DetectCalibrationGrid_CirclesDetects an arbitrary size symmetric circle pattern on the image.
GenerateCalibrationPointsGenerates artificial points for camera calibration. Doesn't support distortion.
ImageEdgesToWorldPlaneFinds the world coordinates of image Edges.
ImageEdgeToWorldPlaneFinds the world coordinates of image Edge.
ImageGapsToWorldPlaneFinds the world coordinates of image Gaps.
ImageGapToWorldPlaneFinds the world coordinates of image Gap.
ImagePathsToWorldPlaneFinds the world coordinates of image Paths.
ImagePathToWorldPlaneFinds the world coordinates of image Path.
ImagePointsToWorldPlaneFinds the world coordinates of image Points.
ImagePointToWorldPlaneFinds the world coordinates of image Point.
ImageRidgesToWorldPlaneFinds the world coordinates of image Ridges.

WorldPlaneRidgeToImageFinds the image coordinates of world plane Ridge.
WorldPlaneSegmentsToImageFinds the image coordinates of world plane Segments.
WorldPlaneSegmentToImageFinds the image coordinates of world plane Segment.
WorldPlaneStripesToImageFinds the image coordinates of world plane Stripes.
WorldPlaneStripeToImageFinds the image coordinates of world plane Stripe.
