Detailed Description

This is a RANSAC-based 3D object recognition method.

Do the following to use it: (i) call addModel() k times with k different models representing the objects to be recognized and (ii) call recognize() with the 3D scene in which the objects should be recognized. Recognition means both object identification and pose (position + orientation) estimation. Check the method descriptions for more details.

Constructor & Destructor Documentation

◆ ObjRecRANSAC()

pcl::recognition::ObjRecRANSAC::ObjRecRANSAC	(	float	pair_width,
		float	voxel_size
	)

Constructor with some important parameters which can not be changed once an instance of that class is created.

Parameters

[in]	pair_width	should be roughly half the extent of the visible object part. This means, for each object point p there should be (at least) one point q (from the same object) such that \|\|p - q\|\| <= pair_width. Tradeoff: smaller values allow for detection in more occluded scenes but lead to more imprecise alignment. Bigger values lead to better alignment but require large visible object parts (i.e., less occlusion).
[in]	voxel_size	is the size of the leafs of the octree, i.e., the "size" of the discretization. Tradeoff: High values lead to less computation time but ignore object details. Small values allow to better distinguish between objects, but will introduce more holes in the resulting "voxel-surface" (especially for a sparsely sampled scene).

Member Function Documentation

◆ addModel()

bool pcl::recognition::ObjRecRANSAC::addModel	(	const PointCloudIn &	points,
		const PointCloudN &	normals,
		const std::string &	object_name,
		void *	user_data = `nullptr`
	)

inline

Add an object model to be recognized.

Parameters

[in]	points	are the object points.
[in]	normals	at each point.
[in]	object_name	is an identifier for the object. If that object is detected in the scene 'object_name' is returned by the recognition method and you know which object has been detected. Note that 'object_name' has to be unique!
[in]	user_data	is a pointer to some data (can be NULL)

The method returns true if the model was successfully added to the model library and false otherwise (e.g., if 'object_name' is already in use).

Computes the rigid transform that maps the line (a1, b1) to (a2, b2).

The computation is based on the corresponding points 'a1' <-> 'a2' and 'b1' <-> 'b2' and the normals 'a1_n', 'b1_n', 'a2_n', and 'b2_n'. The result is saved in 'rigid_transform' which is an array of length 12. The first 9 elements are the rotational part (row major order) and the last 3 are the translation.

Parameters

[in]	scene	is the 3d scene in which the object should be recognized.
[in]	normals	are the scene normals.
[out]	recognized_objects	is the list of output items each one containing the recognized model instance, its name, the aligning rigid transform and the match confidence (see ObjRecRANSAC::Output for further explanations).
[in]	success_probability	is the user-defined probability of detecting all objects in the scene.

◆ setMaxCoplanarityAngleDegrees()

void pcl::recognition::ObjRecRANSAC::setMaxCoplanarityAngleDegrees ( float max_coplanarity_angle_degrees )

This is a threshold.

The larger the value the more point pairs will be considered as co-planar and will be ignored in the off-line model pre-processing and in the online recognition phases. This makes sense only if "ignore co-planar points" is on. Call this method before calling addModel. This method calls the corresponding method of the model library.
