Method Detail

setConfiguration

public void setConfiguration(Se3_F64 planeToCamera,
                             IntrinsicParameters intrinsic)

Configures the camera's intrinsic and extrinsic parameters

Parameters:

planeToCamera - Transform from the plane to the camera

intrinsic - Pixel to normalized image coordinates

setIntrinsic

public void setIntrinsic(IntrinsicParameters intrinsic)

Configures the camera's intrinsic parameters

Parameters:

intrinsic - Intrinsic camera parameters

setPlaneToCamera

public void setPlaneToCamera(Se3_F64 planeToCamera,
                             boolean computeInverse)

Specifies camera's extrinsic parameters.

Parameters:

planeToCamera - Transform from plane to camera reference frame

computeInverse - Set to true if pixelToPlane is going to be called. performs extra calculation

planeToPixel

public boolean planeToPixel(double pointX,
                            double pointY,
                            Point2D_F64 pixel)

Given a point on the plane find the pixel in the image.

Parameters:

pointX - (input) Point on the plane, x-axis

pointY - (input) Point on the plane, y-axis

pixel - (output) Pixel in the image

Returns:

true if the point is in front of the camera. False if not.

planeToNormalized

public boolean planeToNormalized(double pointX,
                                 double pointY,
                                 Point2D_F64 normalized)

Given a point on the plane find the normalized image coordinate

Parameters:

pointX - (input) Point on the plane, x-axis

pointY - (input) Point on the plane, y-axis

normalized - (output) Normalized image coordinate of pixel

Returns:

true if the point is in front of the camera. False if not.

pixelToPlane

public boolean pixelToPlane(double pixelX,
                            double pixelY,
                            Point2D_F64 plane)

                             double normY,
                             Point2D_F64 plane)

Given a pixel in normalized coordinates, find the point on the plane. Make sure invert was set to true in setPlaneToCamera(georegression.struct.se.Se3_F64, boolean)

Parameters:

normX - (input) Image pixel in normalized coordinates, x-axis

normY - (input) Image pixel in normalized coordinates, y-axis

plane - (output) Point on the plane.

Returns:

true if a point on the plane was found in front of the camera
