Member Function Documentation

baseline()

double image_geometry::StereoCameraModel::baseline ( ) const

inline

Returns the horizontal baseline in world coordinates.

Todo:

Currently assuming horizontal baseline

Definition at line 111 of file stereo_camera_model.h.

fromCameraInfo() [1/2]

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.

fromCameraInfo() [2/2]

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.

getDisparity()

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 123 of file stereo_camera_model.h.

getZ()

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 117 of file stereo_camera_model.h.

initialized()

bool image_geometry::StereoCameraModel::initialized ( ) const

inline

Returns true if the camera has been initialized.

Definition at line 94 of file stereo_camera_model.h.

left()

const PinholeCameraModel & image_geometry::StereoCameraModel::left ( ) const

inline

Get the left monocular camera model.

Definition at line 104 of file stereo_camera_model.h.

operator=()

StereoCameraModel & image_geometry::StereoCameraModel::operator=

const StereoCameraModel &

other

Definition at line 20 of file stereo_camera_model.cpp.

projectDisparityImageTo3d()

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 132 of file stereo_camera_model.cpp.

projectDisparityTo3d()

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 115 of file stereo_camera_model.cpp.

reprojectionMatrix()

const cv::Matx44d & image_geometry::StereoCameraModel::reprojectionMatrix ( ) const

inline

Returns the disparity reprojection matrix.

Definition at line 109 of file stereo_camera_model.h.

right()

const PinholeCameraModel & image_geometry::StereoCameraModel::right ( ) const

inline

Get the right monocular camera model.

Definition at line 105 of file stereo_camera_model.h.

tfFrame()

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.

Definition at line 107 of file stereo_camera_model.h.
