bool image_geometry::StereoCameraModel::fromCameraInfo ( const sensor_msgs::CameraInfo &  left,
const sensor_msgs::CameraInfo &  right 
)

Set the camera parameters from the sensor_msgs/CameraInfo messages.

Definition at line 27 of file stereo_camera_model.cpp.

bool image_geometry::StereoCameraModel::fromCameraInfo ( const sensor_msgs::CameraInfoConstPtr &  left,
const sensor_msgs::CameraInfoConstPtr &  right 
)

Set the camera parameters from the sensor_msgs/CameraInfo messages.

Definition at line 47 of file stereo_camera_model.cpp.

double image_geometry::StereoCameraModel::getDisparity ( double  Z) const [inline]

Returns the disparity observed for a point at depth Z.

This is the inverse of getZ().

Definition at line 122 of file stereo_camera_model.h.

double image_geometry::StereoCameraModel::getZ ( double  disparity) const [inline]

Returns the depth at which a point is observed with a given disparity.

This is the inverse of getDisparity().

Definition at line 116 of file stereo_camera_model.h.

Returns true if the camera has been initialized.

Definition at line 93 of file stereo_camera_model.h.

Get the left monocular camera model.

Definition at line 103 of file stereo_camera_model.h.

StereoCameraModel & image_geometry::StereoCameraModel::operator= ( const StereoCameraModel other)

Definition at line 20 of file stereo_camera_model.cpp.

void image_geometry::StereoCameraModel::projectDisparityImageTo3d ( const cv::Mat &  disparity,
cv::Mat &  point_cloud,
bool  handleMissingValues = false 
) const

Project a disparity image to a 3d point cloud.

If handleMissingValues = true, all points with minimal disparity (outliers) have Z set to MISSING_Z (currently 10000.0).

Definition at line 95 of file stereo_camera_model.cpp.

void image_geometry::StereoCameraModel::projectDisparityTo3d ( const cv::Point2d &  left_uv_rect,
float  disparity,
cv::Point3d &  xyz 
) const

Project a rectified pixel with disparity to a 3d point.

Definition at line 78 of file stereo_camera_model.cpp.

const cv::Mat_< double > & image_geometry::StereoCameraModel::reprojectionMatrix ( ) const [inline]

Returns the disparity reprojection matrix.

Definition at line 108 of file stereo_camera_model.h.

Get the right monocular camera model.

Definition at line 104 of file stereo_camera_model.h.

std::string image_geometry::StereoCameraModel::tfFrame ( ) const [inline]

Get the name of the camera coordinate frame in tf.

For stereo cameras, both the left and right CameraInfo should be in the left optical frame.
