void LSDCloudRaster::NearestNeighbourSearch2D	(	float	searchPoint_x,
		float	searchPoint_y,
		int	K,
		vector< float > &	pointValues,
		vector< int > &	pointIndex,
		vector< float > &	pointSquaredDistance
	)

Conducts a focal search (in the xy plane), to find the nearest K points.

Points are arranged according to proximity to the query point

Parameters

float	-> the x coordinate of the query point
float	-> the y coordinate of the query point
int	-> the number of points to find
vector<float>	-> the values associated with the returned points
vector<int>	-> the indexes associated with the returned points
vector<float>	-> the squared distance of the returned points from the query point

void LSDCloudRaster::PointData_to_cloud	(	PointData &	point_data,
		LSDRaster &	raster
	)

Read in data from a PointData (LSDShapeTools) into a LSDCloud.

The point cloud is also structured in an octree for rapid spatial querying. Uses the PCL library (www.poinclouds.org).

Parameters

PointData	-> x,y coordinate strucure to load into cloud
LSDRaster	-> raster used as spatial reference frame

		float	searchPoint_y,
		float	searchRadius,
		vector< float > &	pointValues,
		vector< int > &	pointIndex,
		vector< float > &	pointSquaredDistance
	)

Conducts a focal search (in xy plane), to find all points within defined search radius.

SEARCH TOOLS

Points are arranged according to proximity to the query point

Parameters

float	-> the x coordinate of the query point
float	-> the y coordinate of the query point
float	-> the search radius
vector<float>	-> the values associated with the returned points
vector<int>	-> the indexes associated with the returned points
vector<float>	-> the squared distance of the returned points from the query point

void LSDCloudRaster::raster_to_cloud ( LSDRaster & raster )

Read in data from an LSDRaster into a LSDCloud object.

The point cloud is also structured in an octree for rapid spatial querying. Uses the PCL library (www.poinclouds.org).

Parameters

LSDRaster -> raster to convert to a LSDCloud
