構築子と解体子

Detector()

CV_WRAP cv::linemod::Detector::Detector	(	const std::vector< Ptr< Modality > > &	modalities,
		const std::vector< int > &	T_pyramid
	)

Constructor.

引数

modalities	Modalities to use (color gradients, depth normals, ...).
T_pyramid	Value of the sampling step T at each pyramid level. The number of pyramid levels is T_pyramid.size().

関数詳解

addTemplate()

CV_WRAP int cv::linemod::Detector::addTemplate	(	const std::vector< Mat > &	sources,
		const String &	class_id,
		const Mat &	object_mask,
		CV_OUT Rect *	bounding_box = NULL
	)

Add new object template.

引数

	sources	Source images, one for each modality.
	class_id	Object class ID.
	object_mask	Mask separating object from background.
[out]	bounding_box	Optionally return bounding box of the extracted features.

戻り値

Template ID, or -1 if failed to extract a valid template.

getModalities()

CV_WRAP const std::vector< Ptr< Modality > > & cv::linemod::Detector::getModalities ( ) const

inline

Get the modalities used by this detector.

You are not permitted to add/remove modalities, but you may dynamic_cast them to tweak parameters.

getTemplates()

CV_WRAP const std::vector< Template > & cv::linemod::Detector::getTemplates	(	const String &	class_id,
		int	template_id
	)		const

Get the template pyramid identified by template_id.

For example, with 2 modalities (Gradient, Normal) and two pyramid levels (L0, L1), the order is (GradientL0, NormalL0, GradientL1, NormalL1).

match()

CV_WRAP void cv::linemod::Detector::match	(	const std::vector< Mat > &	sources,
		float	threshold,
		CV_OUT std::vector< Match > &	matches,
		const std::vector< String > &	class_ids = std::vector< String >(),
		OutputArrayOfArrays	quantized_images = noArray(),
		const std::vector< Mat > &	masks = std::vector< Mat >()
	)		const

Detect objects by template matching.

Matches globally at the lowest pyramid level, then refines locally stepping up the pyramid.

引数

	sources	Source images, one for each modality.
	threshold	Similarity threshold, a percentage between 0 and 100.
[out]	matches	Template matches, sorted by similarity score.
	class_ids	If non-empty, only search for the desired object classes.
[out]	quantized_images	Optionally return vector<Mat> of quantized images.
	masks	The masks for consideration during matching. The masks should be CV_8UC1 where 255 represents a valid pixel. If non-empty, the vector must be the same size as sources. Each element must be empty or the same size as its corresponding source.
