Detailed Description

This class detects AR boards Version 1.2 There are two modes for board detection. First, the old way. (You first detect markers with MarkerDetector and then call to detect in this class.

Second: New mode, marker detection is included in the class

Member Function Documentation

float aruco::BoardDetector::detect ( const cv::Mat &  im) throw (cv::Exception)

Detect markers, and then, look for the board indicated in setParams()

Returns:
value indicating the likelihood of having found the marker

Definition at line 64 of file boarddetector.cpp.

float aruco::BoardDetector::detect ( const vector< Marker > &  detectedMarkers,
const BoardConfiguration BConf,
Board Bdetected,
cv::Mat  camMatrix = cv::Mat(),
cv::Mat  distCoeff = cv::Mat(),
float  markerSizeMeters = -1 
) throw (cv::Exception)

Given the markers detected, determines if there is the board passed

Parameters:
detectedMarkersresult provided by aruco::ArMarkerDetector
BConfthe board you want to see if is present
Bdetectedoutput information of the detected board
camMatrixcamera matrix with intrinsics
distCoeffcamera distorsion coeff
camMatrixintrinsic camera information.
distCoeffcamera distorsion coefficient. If set Mat() if is assumed no camera distorion
markerSizeMeterssize of the marker sides expressed in meters
Returns:
value indicating the likelihood of having found the marker
float aruco::BoardDetector::detect ( const vector< Marker > &  detectedMarkers,
const BoardConfiguration BConf,
Board Bdetected,
const CameraParameters cp,
float  markerSizeMeters = -1 
) throw (cv::Exception)

Definition at line 76 of file boarddetector.cpp.

Returns a reference to the board detected

Definition at line 86 of file boarddetector.h.

Returns the vector of markers detected

Definition at line 92 of file boarddetector.h.

Returns a reference to the internal marker detector

Definition at line 89 of file boarddetector.h.

void aruco::BoardDetector::rotateXAxis ( cv::Mat &  rotation) [private]

Definition at line 164 of file boarddetector.cpp.

void aruco::BoardDetector::setParams ( const BoardConfiguration bc,
const CameraParameters cp,
float  markerSizeMeters = -1 
)

Use if you plan to let this class to perform marker detection too

Definition at line 57 of file boarddetector.cpp.

void aruco::BoardDetector::setYPerpendicular ( bool  enable) [inline]

By default, the Y axis is set to point up. However this is not the default operation mode of opencv, which produces the Z axis pointing up instead. So, to achieve this change, we have to rotate the X axis.
