§ 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_itemNumber of items.
rowsRows of a single sample image.
colsColumns of a single sample image.
headerPathPath 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
cloudPoint 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
cloudPoint cloud used for computing the center point.
centercenter 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
