ILCalib ILObject

Properties

LPVTransformType TransformType [get, set]
 The transformation type used for the calibration. By default, it's LPVTransformHomography .
 
- Properties inherited from ILCalib
double CalibError [get]
 The overall RMS re-projection error for the calibration, calculated based on the distances between the image points and the projected (using the optimized calibration matrices) world points. It's defined as:
\( \sqrt{ \frac{1}{n} \sum_{i=0}^{n} distance(p^{image}_i, p^{proj}_i)^2 } \).
 
LPVFixImageMode FixImageMode [get, set]
 The mode to fix image used in FixImage(). More...
 
double FixImageOffsetX [get, set]
 The x-coordinate offset (in pixel unit) of the fixed image used in FixImage(), used together with FixImageOffsetY.
By default, it's 0, means no offset in x-coordinate. You may change the offset to translate the fixed image, for example move the inspect region to the center of the fixed image.
 
double FixImageOffsetY [get, set]
 The y-coordinate offset (in pixel unit) of the fixed image used in FixImage(), used together with FixImageOffsetX.
By default, it's 0, means no offset in y-coordinate. You may change the offset to translate the fixed image, for example move the inspect region to the center of the fixed image.
 
double FixImageScale [get, set]
 The scale of the fixed image used in FixImage().
By default, it's 1, means no scale. You may change the scale factor to zoom in/out the fixed image.
 
LPVInterpolationMethod InterpolationMethod [get, set]
 The interpolation method used in fix the image for undistortion (and untilt). By default, it's LPVInterCubic.
 
LPVCalibModel Model [get]
 The calibration model.
 
BOOL UseCache [get, set]
 Whether to make use of cache which is used to speed-up the process of the image undistortion (and untilt), but consume more memory. By default, it's off.

Detailed Description

This interface provide functionalities of the n-points camera model.

In the n-points camera model, the calibration is represented as a transform matrix, which could be rigid/similar/affine/homography transformation as desired. This model does not support distortion calibration.

To use this interface, you should create a LCalibNPoints object.
