vTools#

vToolsは、Workbenchを使用して画像処理デザインを作成するためのビルディングブロックです。

それぞれのvToolは、特定のタスク（数例を挙げるとすれば、カメラのキャリブレーション、画像形式の変換、バーコードの読み取りなど）を実行できます。Workbenchに、必要なvToolsを追加し、必要な順序でそれらを接続してから、そのデザインをレシピファイル（.precipe）として保存します。最後に、レシピをアプリケーションに追加できます。

When configuring the vTools, you can quickly test any changes you make by loading an image and running the recipe. In a section of the Workbench called the pin data view, you can see the results at runtime. Adjust the settings and repeat this process until you're satisfied.

Integrating vTools Into Your Application#

To integrate the image processing design into your own application, use the pylon C++ Data Processing API, which offers a variety of simple functions for loading and executing recipes as well as for evaluating the results in your program code.

Changes made to the recipe settings in the pylon Viewer become effective when you load the recipe into your application again. You don't have to change or recompile the application code.

The pylon C++ Data Processing API provides a set of samples that demonstrate certain common use cases. Incorporated in the sample code are a number of demo vTools.

For more information, see the pylon C++ Data Processing Programmer's Guide available in the Help menu of the pylon Viewer or in the pylon installation directory (usually C:\Program Files\Basler\pylon\Development\Documentation\PylonCppDataProcessingSDK.chm).

使用可能なvTools#

Some vTools are free and included in the pylon Viewer setup. For others you need a license. For more information about how to obtain and activate licenses, see vTool Licensing.

Apart from licenses for individual vTools, you can buy combinations of vTools that have been bundled together in one license, e.g., vTools required for a specific use case.

Licenses and Bundles#

Some vTools can be bought individually, others are available as part of a bundle, e.g., for a specific use case like Color Blob Analysis. Below is an overview of the available licenses and license bundles.

Blob Analysis Basic#

The Blob Analysis license includes pylon vTools for typical thresholding-based blob analysis tasks, such as identifying regions by their grey value range.

In combination with the region vTools, you can use the thresholding vTools to identify and analyze regions, objects, and structures with outstanding robustness, accuracy, and performance.

The license includes the following vTools:

Color Blob Analysis Basic#

The Color Blob Analysis license includes pylon vTools for blob analysis tasks that can't be solved with common grayscale thresholding techniques, e.g., identifying objects by color.

You just have to load an image (either a live image or an image from disk) and mark the pixels belonging to the object you're interested in to teach a model that you can then apply to new images. In combination with the region vTools, you can use the model to identify and analyze regions, objects, and structures with outstanding robustness, accuracy, and performance.

The license includes the following vTools:

Measurements Pro#

The Measurements Pro license provides vTools for measuring distances between edges along a single line as well as measuring geometric shapes such as rectangles and circles.

You can use the measurements vTools in combination with the Calibration vTool. By connecting the vTools, all distances measured are then returned in the calibrated unit.

The license includes the following vTools:

Preprocessing Basic#

The Preprocessing Basic license provides vTools for arithmetic operations as well as smoothing and morphology operations on images.

With these high-performance algorithms, you can enhance, mask, or weaken image features in order to improve and optimize images for further processing steps.

The license includes the following vTools:

To buy a license, visit the Basler website.

Code Reader Bundle#

The Code Reader Bundle license includes all code reading vTools in Basic and Pro versions.

To buy a license, visit the Basler website.

General vTools Pro Bundle#

The General vTools Pro Bundle license gives you access to a wide range of Basler vTools. The following bundles and individual vTools are included:

較正vTool
Geometric Pattern Matching
OCR vTool
Template Matching
Code Reader Bundle
Blob Analysis Basic
Color Blob Analysis Basic
Measurements Pro
Preprocessing Basic

入力ピンと出力ピン#

それぞれのvToolには、vToolsにデータを供給し、デザインの次の手順にデータを渡すための入力ピンと出力ピンがあります。vToolsを接続するには、出力ピンをクリックし、同じタイプの別のvToolの入力ピンに接続をドラッグします。すなわち、Camera vToolのImage出力ピンをBarcode Reader vToolのImage入力ピンにドラッグします。

入力端子と出力端子は、レシピの入力／出力ピンと見なすことができます。入力端子を使用して、データをvToolの入力ピンにプッシュし、出力端子を使用して、データをvToolの出力ピンから受信できます。

次のスクリーンショットは、vToolsと端末の接続方法を示しています。

ミニマップ#

レシピに多数のvToolsが含まれている場合、[Workbench]ペインのサイズによっては、すべてが表示されないことがあります。そのような状況では、可視エリアの外側でvToolsを表示するミニマップを確認できます。

vToolsの設定#

vToolに応じて、設定ダイアログまたは[Features - All]ペインのvToolパラメーターを介して、あるいはその両方を組み合わせて、設定することができます。詳細については、設定するvToolのトピックを参照してください。
