Method Detail

setCalibration

public void setCalibration(MonoPlaneParameters param)

Description copied from interface: MonocularPlaneVisualOdometry

Specifies the camera's intrinsic and extrinsic parameters. Can be changed at any time.

Specified by:

setCalibration in interface MonocularPlaneVisualOdometry<T extends ImageBase>

Parameters:

param - Camera calibration parameters

process

public boolean process(T input)

Description copied from interface: MonocularPlaneVisualOdometry

Process the new image and update the motion estimate. The return value must be checked to see if the estimate was actually updated. If false is returned then VisualOdometry.isFault() also needs to be checked to see if the pose estimate has been reset.

Specified by:

process in interface MonocularPlaneVisualOdometry<T extends ImageBase>

Parameters:

input - Next image in the sequence.

Returns:

If the motion estimate has been updated or not

getImageType

public ImageType<T> getImageType()

Description copied from interface: MonocularPlaneVisualOdometry

Type of input images it can process.

Specified by:

getImageType in interface MonocularPlaneVisualOdometry<T extends ImageBase>

Returns:

The image type

reset

public void reset()

Description copied from interface: VisualOdometry

Forget past history and tracking results, returning it to its initial state.

Specified by:

reset in interface VisualOdometry<Se3_F64>

isFault

public boolean isFault()

Description copied from interface: VisualOdometry

If a fatal error occurred while updating its state then this function will return true. Before more images can be processed VisualOdometry.reset() must be called. Only needs to be called if process returns false.

Specified by:

isFault in interface VisualOdometry<Se3_F64>

Returns:

true if a fatal error has occurred.

getCameraToWorld

public Se3_F64 getCameraToWorld()

Description copied from interface: VisualOdometry

Returns the estimated motion relative to the first frame in which a fatal error does not happen.

Specified by:

getCameraToWorld in interface VisualOdometry<Se3_F64>

Returns:

Found pose.

getTrackLocation

public Point3D_F64 getTrackLocation(int index)

Description copied from interface: AccessPointTracks3D

Returns the 3D location of the active track. If there is no location estimate yet then return null.

Specified by:

getTrackLocation in interface AccessPointTracks3D

Parameters:

index - The track's index in the active list

Returns:

Location of the track or null otherwise

getTrackId

public long getTrackId(int index)

Description copied from interface: AccessPointTracks

Used to get the track ID of an active Track

Specified by:

getTrackId in interface AccessPointTracks

Parameters:

index - which track

Returns:

The track's ID

getAllTracks

public java.util.List<Point2D_F64> getAllTracks()

Description copied from interface: AccessPointTracks

All the points being actively tracked in pixel coordinates.

Specified by:

getAllTracks in interface AccessPointTracks

Returns:

all active tracks in pixel coordinates

isInlier

public boolean isInlier(int index)

Description copied from interface: AccessPointTracks

True if the specified track is an inlier used in motion estimation

Specified by:

isInlier in interface AccessPointTracks

Parameters:

index - The index in all

Returns:

if it is an inlier or not

isNew

public boolean isNew(int index)

Description copied from interface: AccessPointTracks

True if the specified track was just spawned

Specified by:

isNew in interface AccessPointTracks

Parameters:

index - The index in all

Returns:

if it is new or not
