◆ getCameraLocation()

cv::Point3f aruco::CameraParameters::getCameraLocation ( cv::Mat  Rvec,
cv::Mat  Tvec 
)
static

Returns the location of the camera in the reference system given by the rotation and translation vectors passed NOT TESTED

Definition at line 87 of file cameraparameters.cpp.

◆ getRTMatrix()

cv::Mat aruco::CameraParameters::getRTMatrix ( const cv::Mat &  R_,
const cv::Mat &  T_,
int  forceType 
)
static

cv::Size  size,
double  proj_matrix[16],
double  gnear,
double  gfar,
bool  invert = false 
)
throw (cv::Exception
)

Given the intrinsic camera parameters returns the GL_PROJECTION matrix for opengl. PLease NOTE that when using OpenGL, it is assumed no camera distorsion! So, if it is not true, you should have undistor image

Parameters
orgImgSizesize of the original image
sizeof the image/window where to render (can be different from the real camera image). Please not that it must be related to CamMatrix
proj_matrixoutput projection matrix to give to opengl
gnear,gfarvisible rendering range
invertindicates if the output projection matrix has to yield a horizontally inverted image because image data has not been stored in the order of glDrawPixels: bottom-to-top.

Definition at line 196 of file cameraparameters.cpp.

◆ isValid()

bool aruco::CameraParameters::isValid ( ) const
inline

Indicates whether this object is valid

Definition at line 68 of file cameraparameters.h.

◆ norm()

double aruco::CameraParameters::norm ( double  a,
double  b,
double  c 
)
staticprivate

Definition at line 220 of file cameraparameters.cpp.

◆ OgreGetProjectionMatrix()

void aruco::CameraParameters::OgreGetProjectionMatrix ( cv::Size  orgImgSize,
cv::Size  size,
double  proj_matrix[16],
double  gnear,
double  gfar,
bool  invert = false 
)
throw (cv::Exception
)

setup camera for an Ogre project. Use: ... Ogre::Matrix4 PM(proj_matrix[0], proj_matrix[1], ... , proj_matrix[15]); yourCamera->setCustomProjectionMatrix(true, PM); yourCamera->setCustomViewMatrix(true, Ogre::Matrix4::IDENTITY); ... As in OpenGL, it assumes no camera distorsion

Definition at line 357 of file cameraparameters.cpp.
