Input

An image containing a gasket.

Output

Saved image with drawn results.

ヒント

Read more about the original Gasket Inspection example here. In order to reduce the execution time, draw and save results using a Worker Task Macrofilter.

Solution (AVS)

Use the code from the Gasket Inspection example to prepare the inspection.
From the Project Explorer window create a new UserType named InspectionPacket. All the inputs, which need to be created, as well as their corresponding data types are shown in the image below.
From the Project explorer window create a new SavingQueue with the InspectionPacket data type.
From the Project explorer window create a new Worker Task called SaveLastImage.
Add the Queue_Push filter to the main program's PROCESSING section and assign it the SavingQueue queue.
Right click on the inValue of the Queue_Push filter and select "Expand Structure Fields".
Connect created inputs using the following scheme:
- Connect the outImage output of the EnumerateImages filter with the inValue.Image input of the Queue_Push filter,
- Connect the outMatch output of the LocateSingleObject_Edges1 filter with the inValue.Rectangle input of the Queue_Push filter,
- Connect the outCircle output of the first FitCircleToEdges filter with the inValue.Circle1 input of the Queue_Push filter,
- Connect the outCircle output of the the second FitCircleToEdges filter with the inValue.Circle2 input of the Queue_Push filter,
- Connect the outConnectingSegment output of the first PointToPointDistance filter with the inValue.Segment1 input of the Queue_Push filter,
- Connect the outArc output of the first FitArcToEdges filter with the inValue.Arc1 input of the Queue_Push filter,
- Connect the outArc output of the second FitArcToEdges filter with the inValue.Arc2 input of the Queue_Push filter,
- Connect the outConnectingSegment output of the the second PointToPointDistance filter with the inValue.Segment2 input of the Queue_Push filter.
Go to the SaveLastImage Worker Task macrofilter.
In the ACQUIRE section add the Queue_Pop and the Loop filters.
In the PROCESS section add following filters in specified order: the DrawRectangles_SingleColor, the DrawCircles_SingleColor, the DrawCircles_SingleColor, the DrawSegments_SingleColor, the DrawArcs_SingleColor, the DrawArcs_SingleColor, the DrawSegments_SingleColor and the SaveImage.
Right click on the outValues of the Queue_Pop filter, select the PropertyOutput and check all visible outputs.
Connect created outputs by following the scheme in the image below.
Set the inFile input of the SaveImage filter to LastResult.bmp.
Program is ready to use. In the current version, programs using worker tasks can be properly run only in the Run mode (F5).

マクロフィルタメイン

使用したフィルタ

アイコン	名前	説明
	DrawRectangles_SingleColor	画像上に単色で四角形を描画します。
	DrawCircles_SingleColor	単一の色で画像上に円を描画します。
	LocateSingleObject_Edges1	輪郭がシャープで硬い物体の検出。多くの場合、プログラムの最初のフィルターの 1 つです。
	FitArcToEdges	Precise detection of an arciform edge, whose rough location is known beforehand.
	Loop	このフィルターを、ループを持つ必要があるタスクに配置しますが、他のループジェネレーター (例: GrabImage) を持たないようにします。
	PointToPointDistance	2つの点の間の距離を測定します。
	SaveImage	Saves an image to a file.
	DrawSegments_SingleColor	Draws segments on an image with a single color.
	DrawArcs_SingleColor	Draws arcs on an image with a single color.
	EnumerateImages	ディスクに保存された画像を使用して画像取得をエミュレートします。
	FitCircleToEdges	既知の粗い位置に基づいて円形のオブジェクトまたは穴を正確に検出します。
