 |
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 |
|
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 |

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 |
 |
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. |
