Member Function Documentation

init()

virtual bool rtabmap::DBReader::init ( const std::string &  calibrationFolder = ".", const std::string &  cameraName = ""  )

virtual

Initializes the sensor.

Pure virtual method that must be implemented by derived classes to initialize the sensor hardware or data source. This typically involves:

• Opening device connections or file streams
• Loading camera calibration parameters
• Configuring sensor settings

Parameters

calibrationFolder	Directory path where calibration files are located (default: current directory ".")
cameraName	Base name of the camera for loading calibration files (default: empty string)

Returns

True if initialization was successful, false otherwise

Note

Must be called before calling takeData() or captureData()

Implements rtabmap::SensorCapture.

isCalibrated()

virtual bool rtabmap::DBReader::isCalibrated ( ) const

virtual

Implements rtabmap::Camera.

getSerial()

virtual std::string rtabmap::DBReader::getSerial ( ) const

virtual

Returns the sensor's serial number or unique identifier.

Pure virtual method that must be implemented by derived classes to return a unique identifier for the sensor (e.g., device serial number, file path, or other identifier).

Returns

String identifier for the sensor

Implements rtabmap::SensorCapture.

odomProvided()

virtual bool rtabmap::DBReader::odomProvided ( ) const

inlinevirtual

Checks if the sensor provides odometry poses.

Some sensors (e.g., visual-inertial cameras) can provide pose estimates directly. This method indicates whether the sensor supports pose queries.

Returns

True if the sensor provides odometry poses, false otherwise

Note

Default implementation returns false. Derived classes should override if they support pose estimation.

getPose()

Reimplemented from rtabmap::SensorCapture.

Definition at line 90 of file DBReader.h.

getPose()

virtual bool rtabmap::DBReader::getPose ( double  stamp, Transform &  pose, cv::Mat &  covariance, double  maxWaitTime = 0.06  )

virtual

Gets the sensor's pose estimate at a specific timestamp.

Queries the sensor for its pose estimate at the given timestamp. This is typically used for sensors that provide visual-inertial odometry or other pose estimation capabilities.

Parameters

	stamp	Timestamp in seconds for which to query the pose
[out]	pose	Output transform representing the sensor pose
[out]	covariance	Output covariance matrix (6x6) representing twist uncertainty
	maxWaitTime	Maximum time in seconds to wait for pose data (default: 0.06)

Returns

True if pose was successfully retrieved, false otherwise

Note

Default implementation returns false. Derived classes should override if they support pose estimation.
