Detailed Description

Object that can compute the normals in an image. It is an object as it can cache data for speed efficiency The implemented methods are either:

• FALS (the fastest) and SRI from Fast and Accurate Computation of Surface Normals from Range Images by H. Badino, D. Huber, Y. Park and T. Kanade
• the normals with bilateral filtering on a depth image from Gradient Response Maps for Real-Time Detection of Texture-Less Objects by S. Hinterstoisser, C. Cagniart, S. Ilic, P. Sturm, N. Navab, P. Fua, and V. Lepetit

Member Function Documentation

apply()

virtual void cv::RgbdNormals::apply ( InputArray points, OutputArray normals ) const

pure virtual

Python:
	cv.RgbdNormals.apply(	points[, normals]	) ->	normals

Given a set of 3d points in a depth image, compute the normals at each point.

Parameters

points	a rows x cols x 3 matrix of CV_32F/CV64F or a rows x cols x 1 CV_U16S
normals	a rows x cols x 3 matrix

cache()

virtual void cv::RgbdNormals::cache ( ) const

pure virtual

Python:
	cv.RgbdNormals.cache(		) ->	None

Prepares cached data required for calculation If not called by user, called automatically at first calculation

create()

static Ptr< RgbdNormals > cv::RgbdNormals::create ( int rows = 0, int cols = 0, int depth = 0, InputArray K = noArray(), int window_size = 5, float diff_threshold = 50.f, RgbdNormals::RgbdNormalsMethod method = RgbdNormals::RgbdNormalsMethod::RGBD_NORMALS_METHOD_FALS )

static

Python:
	cv.RgbdNormals.create(	[, rows[, cols[, depth[, K[, window_size[, diff_threshold[, method]]]]]]]	) ->	retval
	cv.RgbdNormals_create(	[, rows[, cols[, depth[, K[, window_size[, diff_threshold[, method]]]]]]]	) ->	retval

Creates new RgbdNormals object

Parameters

rows	the number of rows of the depth image normals will be computed on
cols	the number of cols of the depth image normals will be computed on
depth	the depth of the normals (only CV_32F or CV_64F)
K	the calibration matrix to use
window_size	the window size to compute the normals: can only be 1,3,5 or 7
diff_threshold	threshold in depth difference, used in LINEMOD algirithm
method	one of the methods to use: RGBD_NORMALS_METHOD_SRI, RGBD_NORMALS_METHOD_FALS
