Detailed Description

To calibrate the camera optic feature points of an calibration pattern must be extracted.

This class extracts the center of gravity of e.g. dark circular control points on a white background. The control points must be placed on a rectangular pattern, wich may be recorded under perspective distortion.

The output is a matrix where the feature point in the i-th row and j-th column corresponds to the control point in the i-th row and j-th column of the calibration pattern. Because a very simple algorithm for sorting the feature points is used, the perspective distortion is limited in such a way that either all x-coordinates of the points in one column must be smaller than all x-coordinates of the points in the next column or all y-coordinates of all points in one row respectively.

Member Function Documentation

bool lti::calibrationBlobFeatures::apply	(	const channel8 &	src,
		matrix< point > &	dest
	)

Computes a matrix with all calibration features from a grey value image.

Returns:

true on success and false otherwise. E.g. false is returned if the number of expected calibration features could not be extracted.

bool lti::calibrationBlobFeatures::apply	(	const image &	src,
		matrix< point > &	dest
	)

Computes a matrix with all calibration features.

The image will be converted to grey-values by averaging all 3 channels. Returns true on success and false otherwise. E.g. false is returned if the number of expected calibration features could not be extracted.
