YellowPixel

open class YellowPixel : ColourThreshold

Yellow pixel processor. These values may not be tuned for your specific camera, lighting, or field conditions, and are tuned based on our own testing. You may need to adjust these values to get the best results for your own robot.

Since

1.0.0-pre

Constructors

YellowPixel

constructor()

Using YCrCb colour space.

Inherited functions

clearData

open fun clearData()

Manually clear the data list.

delegate

open fun delegate(@NonNull delegateTo: Processor)

Delegate this processor to another processor.

getData

open fun getData(): ArrayList<T>

Get the list of vision data.

getFrameBitmap

abstract fun getFrameBitmap(p: Continuation<out Consumer<Bitmap>>)

open fun getFrameBitmap(continuation: Continuation<out Consumer<Bitmap>>)

getLower

open fun getLower(): Scalar

Gets the lower scalar to use for thresholding.

getUpper

open fun getUpper(): Scalar

Gets the upper scalar to use for thresholding.

init

abstract fun init(p: Int, p1: Int, p2: CameraCalibration)

open fun init(width: Int, height: Int, calibration: CameraCalibration)

isAttached

open fun isAttached(): Boolean

Determine whether the processor is attached to a Vision instance.

onAttach

protected open fun onAttach()

Override this method to run any additional code that will be executed when this processor is attached (via init()) by a Vision instance.

onDrawFrame

abstract fun onDrawFrame(p: Canvas, p1: Int, p2: Int, p3: Float, p4: Float, p5: Any)

fun onDrawFrame(canvas: Canvas, onscreenWidth: Int, onscreenHeight: Int, scaleBmpPxToCanvasPx: Float, scaleCanvasDensity: Float, userContext: Any)

Use onFrameDraw instead, which passes a canvas.

onFrameDraw

protected fun onFrameDraw(canvas: Canvas)

Called by the vision system to draw on the frame.

onProcessFrame

protected fun onProcessFrame(frame: Mat, captureTimeNanos: Long)

Called by the vision system to process a frame

onRunning

protected open fun onRunning()

Override this method to run any additional code that will be executed when this processor starts streaming (via start()) on a Vision instance.

processFrame

abstract fun processFrame(p: Mat, p1: Long): Any

fun processFrame(f: Mat, captureTimeNanos: Long): Any

resetLower

open fun resetLower()

Resets the lower override, so that the lower scalar is used instead of the override.

resetUpper

open fun resetUpper()

Resets the upper override, so that the upper scalar is used instead of the override.

setLower

open fun setLower(lower: Scalar)

Forces this upper scalar to be used instead of the scalar supplied by the subclass.

setUpper

open fun setUpper(upper: Scalar)

Forces this lower scalar to be used instead of the scalar supplied by the subclass.

update

protected fun update()

Called to update new data from the vision system, which involves interpreting, collecting, or otherwise processing new vision data per frame.
