Constructor & Destructor Documentation

icoSphere()

cv::cnn_3dobj::icoSphere::icoSphere	(	float	radius_in,
		int	depth_in
	)

Generating a sphere by mean of a iteration based points selection process.

Parameters

radius_in	Another radius used for adjusting the view distance.
depth_in	Number of interations for increasing the points on sphere.

Member Function Documentation

createHeader()

static void cv::cnn_3dobj::icoSphere::createHeader ( int  num_item, int  rows, int  cols, const char *  headerPath  )

static

Create header in binary files collecting the image data and label.

Parameters

num_item	Number of items.
rows	Rows of a single sample image.
cols	Columns of a single sample image.
headerPath	Path where the header will be stored.

getCenter()

cv::Point3d cv::cnn_3dobj::icoSphere::getCenter

(

cv::Mat

cloud

)

Get the center of points on surface in .ply model.

Parameters

cloud

Point cloud used for computing the center point.

getRadius()

float cv::cnn_3dobj::icoSphere::getRadius	(	cv::Mat	cloud,
		cv::Point3d	center
	)

Get the proper camera radius from the view point to the center of model.

Parameters

cloud	Point cloud used for computing the center point.
center	center point of the point cloud.

swapEndian()

static int cv::cnn_3dobj::icoSphere::swapEndian ( int  val )

static

Suit the position of bytes in 4 byte data structure for particular system.

writeBinaryfile()

static void cv::cnn_3dobj::icoSphere::writeBinaryfile ( String  filenameImg, const char *  binaryPath, const char *  headerPath, int  num_item, int  label_class, int  x, int  y, int  z, int  isrgb  )

static

Write binary files used for training in other open source project including Caffe.

Parameters

filenameImg	Path which including a set of images.
binaryPath	Path which will output a binary file.
headerPath	Path which header belongs to.
num_item	Number of samples.
label_class	Class label of the sample.
x	Pose label of X.
y	Pose label of Y.
z	Pose label of Z.
isrgb	Option for choice of using RGB images or not.
