drawTargetOrigin()

void industrial_calibration::TargetFinderOpenCV::drawTargetOrigin	(	const cv::Mat &	image,
		const TargetFeatures2D &	features,
		const double	axis_length = 0.1
	)		const

This method computes the homography matrix between the detected target features and the known target features and uses it to project the X and Y axes of the target origin onto the image.
