Class PanTiltCalibrator

java.lang.Object
  ch.unizh.ini.jaer.hardware.pantilt.PanTiltCalibrator

All Implemented Interfaces:

java.beans.PropertyChangeListener, java.util.EventListener, FrameAnnotater

public class PanTiltCalibrator
extends java.lang.Object
implements java.beans.PropertyChangeListener, FrameAnnotater

The calibrator for the PanTilt. It maintains the calibration from retinal to pan tilt values and in conjunction with PanTiltGUI allows manual calibration of the transform from retinal to pan-tilt space.

Constructor Summary

PanTiltCalibrator(CalibratedPanTilt panTilt)

Method Summary

void	annotate(float[][][] frame) annotate the RGB frame somehow by color pixels in the rendered pixel frame data.
void	annotate(javax.media.opengl.GLAutoDrawable drawable) Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active).
void	annotate(java.awt.Graphics2D g) each annotator is called by the relevant class (e.g.
float[]	getTransformedPanTiltFromXY(float[] xy1)
boolean	isAnnotationEnabled()
boolean	isCalibrating()
void	propertyChange(java.beans.PropertyChangeEvent evt)
void	resetToDefaultCalibration() Resets to a default calibration
void	setAnnotationEnabled(boolean yes)
void	setCalibrating(boolean calibrating)

public PanTiltCalibrator(CalibratedPanTilt panTilt)

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent evt)

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

getTransformedPanTiltFromXY

public float[] getTransformedPanTiltFromXY(float[] xy1)

resetToDefaultCalibration

public void resetToDefaultCalibration()

Resets to a default calibration

isCalibrating

public boolean isCalibrating()

setCalibrating

public void setCalibrating(boolean calibrating)

setAnnotationEnabled

public void setAnnotationEnabled(boolean yes)

Specified by:

setAnnotationEnabled in interface FrameAnnotater

isAnnotationEnabled

public boolean isAnnotationEnabled()

Specified by:

isAnnotationEnabled in interface FrameAnnotater

annotate

public void annotate(float[][][] frame)

Description copied from interface: FrameAnnotater

annotate the RGB frame somehow by color pixels in the rendered pixel frame data.

Specified by:

annotate in interface FrameAnnotater

Parameters:

frame - the RGB pixel information. First dimension is Y, second is X, third is RGB

annotate

public void annotate(java.awt.Graphics2D g)

Description copied from interface: FrameAnnotater

each annotator is called by the relevant class (e.g. EyeTracker) and enters annotate with graphics context current, in coordinates with pixel 0,0 in UL corner and pixel spacing 1 unit before scaling transform (which is already active).

Specified by:

annotate in interface FrameAnnotater

Parameters:

g - the Graphics2D context

annotate

public void annotate(javax.media.opengl.GLAutoDrawable drawable)

Description copied from interface: FrameAnnotater

Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active). The FrameAnnotater then can use JOGL calls to render to the screen by getting the GL context, e.g. the following code, used in the context of an AEChip object, draws a golden lines from LL to UR of the pixel array.

        GL gl = drawable.getGL();
        gl.glBegin(GL.GL_LINES);
        gl.glColor3f(.5f, .5f, 0);
        gl.glVertex2f(0, 0);
        gl.glVertex2f(getSizeX() - 1, getSizeY() - 1);
        gl.glEnd();
 

Specified by:

annotate in interface FrameAnnotater

Parameters:

drawable - the OpenGL drawable components, e.g., GLCanvas
