Field Detail

detectionResult

public final DetectionResult detectionResult

Contour detection result status. Typically used to decide whether contour detection was successful or not and what can be improved from user side.

polygon

public final java.util.List<android.graphics.PointF> polygon

Detected polygon. If no polygon was detected - empty list. Points of polygon are normalized values between 0 and 1 relatively to the size of the frame.

For instance, point.x = 0.5f means that point is centered horizontally in the frame. point.y = 1.0f means that point is at the bottom of the frame and so on.

Note, that points are not rotated by frameOrientation.

frameOrientation

public final int frameOrientation

Rotation of the frame in degrees relatively to what is seen on the screen. Frames might come in different orientation from the camera, that's why this value is needed. You might use it to compensate rotation of polygon.

frameWidth

public final int frameWidth

Width of the frame before rotation

frameHeight

public final int frameHeight

Height of the frame before rotation
