DisplayableQuadDetection

public DisplayableQuadDetection(int detectionStatus,
                                @NonNull
                                float[] transformMatrix,

                                float[] displayLocation)

Constructor for displayable quad detection. Usually invoked from native code.

Parameters:

detectionStatus - Detection status from native library.

transformMatrix - Transformation matrix from native library.

displayLocation - Display location in coordinate system of image on which detection was performed

Method Detail

getDisplayLocation

@NonNull
public Quadrilateral getDisplayLocation()

Returns the display location in coordinate system of image on which detection was performed.

Returns:

the display location in coordinate system of image on which detection was performed.

getTransformedDisplayLocation

@NonNull
public Quadrilateral getTransformedDisplayLocation()

Returns the display location in normalized coordinate system of visible camera frame. The normalized coordinate system of visible camera frame is coordinate system whose top left position is at coordinates (0,0), and bottom right is at coordinates (1,1). It is oriented in landscape right orientation. For more information about display location, see DisplayableQuadDetection.getDisplayLocation().

Returns:

the display location in normalized coordinate system of visible camera frame.
