Image Spatial Transforms Maps

Icon Name Description / Applications Modules
AccessSpatialMap

Returns individual fields of a spatial map.

Calibration
AddSpatialMaps

Combines two spatial maps.


Makes it possible to use single RemapImage filter even if there are two or more image remapping operations (e.g. lens distortion + perspective distortion).

Calibration
CombineSpatialMaps

Combines two spatial maps.


Makes it possible to use single RemapImage filter even if there are two or more image remapping operations (e.g. lens distortion + perspective distortion).

Calibration
ConvertMatrixMapsToSpatialMap

Joins two matrices of coordinates to produce a SpatialMap for use in RemapImage.

Calibration
ConvertSpatialMap

Converts a spatial map to a different format.

Calibration
ConvertSpatialMap_ToNearest

Converts any spatial map to NearestNeighbour interpolation.


Reducing quality for the purpose of speed.

Calibration
ConvertSpatialMapToMatrixMaps

Splits a spatial map into two matrices of source coordinates.

Calibration
CreateCylinderMap

Creates a spatial map for transformations from a cylinder surface to a flat rectangle.


Inspection of the surface of bottles and other cylindrical objects. The result is used by RemapImage.

Calibration
CreateImageInversePolarTransformMap

Creates a spatial map representing an image inverse polar transform.


Data preprocessing for fast inverse polar transform. The result is used by RemapImage.

Calibration
CreateImagePolarTransformMap

Creates a spatial map representing an image polar transform.


Data preprocessing for fast image polar transform. The result is used by RemapImage.

Calibration
CreateImageResizeMap

Creates a spatial map representing an image resizing.


Data preprocessing for fast image resize between two constant sizes. The result is used by RemapImage.

Calibration
CreateImageRotationMap

Creates a spatial map representing an image rotation.


Preprocessing data for fast image rotation by a constant angle. The result is used by RemapImage.

Calibration
CreateMatrixTransformMap

Creates a spatial map which performs transform defined as a 3x3 homography matrix.

Calibration
CreatePerspectiveMap_Path

Creates a perspective transform map from planes defined by paths.


Data preprocessing for fast perspective correction. The result is used by RemapImage.

Calibration
CreatePerspectiveMap_Points

Creates a perspective transform map from four points denoting a rectangle in the world coordinates.


Data preprocessing for fast perspective correction. The result is used by RemapImage.

Calibration
CreatePincushionMap

Creates a spatial map for removing/adding pincushion distortion, using divisional lens distortion model.


The easiest way to remove typical lens distortion. Use together with RemapImage.

Calibration
CreateSphereMap

Creates a spatial map for transformations from a sphere surface to a flat rectangle.


Inspection of the surface of balls and other spherical objects. The result is used by RemapImage.

Calibration
CropSpatialMap

Crops a spatial map to the specified input and output boxes.

Calibration
LoadSpatialMap

Deserializes a SpatialMap object from a AVDATA file.

Calibration
RemapImage

Applies a precomputed image transform, defined by a spatial map object.


Fast (precomputed) image transformations, especially for view undistortion or object geometry correction (e.g. pos recognition of labels on cylindrical bottles).

Calibration
SaveSpatialMap

Serializes a SpatialMap object to an AVDATA file.

Calibration
TestSpatialMapApplicability

Checks if a spatial map may be applied to transform the given image.

Calibration
UnmapPoint

Computes locations of image point on the source image from image point location on remapped image.
