Views for Inspection

Size Distribution View

The Size Distribution view displays the particle results for the selected standard. You can filter the results by approval status, particle type or particle size class.

In the Image Gallery, all particles are displayed from 5 µm length and width onwards. As a Supervisor, you can change the minimum size of the displayed particles in the Region Filter tool in the Region Filter workbench. By default, the Region Filter workbench is set to run silent, see Region Filter.

For individually created job templates it is recommended to display only standards with the same smallest particle size in the Standard Selection tool and adapted the Region Filter tool accordingly.

Image Gallery

Displays all detected particles. Default: Minimized view. The Mid-Sized view shows the particle images with an enlarged zoom level. See TCA Image Gallery.

Class Chart - Diagram

This diagram displays the particle size distribution and the approval status by particle type. The capital letters at the x-axis are representative for the particle size classes according to ISO 16232 and VDA 19.1.

The bars are either displayed in green or red color corresponding to the approval status OK or NOK. The coloring and the corresponding approval status are dependent on the acceptance criteria as defined in the Standard Template. If no approval is defined, the bars are represented in gray color.

Click the Filter NOK Button to show only those particles in the Image Gallery that exceed the limits as defined by the acceptance criteria.

Click one or more bar(s) in the diagram to filter the Image Gallery accordingly.

Class Chart - Length Class Table

This table displays the particle size distribution by particle type. The default length classification parameter is Feret Max.

The displayed particle size classification table shows the following information:

  • The absolute and/or normalized particle counts, according to the selection in the Displayed Normalization tool.
  • The Allowed Number of Particles as defined in the standard template.
  • The corresponding cleanliness level as defined in the standard.
  • The Total Fiber Length sums up the fiber length values.
  • The approval result (OK/NOK).

The table is saved to the archive and is shown in the report.

Note that there is no interaction with the Image Gallery.

Scatter Plot

This diagram displays the distribution of particles in relation to their length and width.

Each particle is indicated by a measuring point and is either displayed in green or red color corresponding to the approval status OK or NOK. The coloring and the corresponding approval status is dependent on the acceptance criteria as defined in the standard template.

If no acceptance criteria are defined, the measuring points are displayed in gray color.

Click Filter NOK to show those particles in the Image Gallery that exceed the limits as defined by the acceptance criteria. From the Type drop-down list, select a certain particle type in the scatter plot to filter the particle gallery accordingly.

Editing Particle Analysis Results in the Particle Edit View

You can display sections of the original tile images instead of a thumbnail image in 2D view and edit them. In case the quality of the result is not satisfactory because for instance adjacent particles touch each other, you edit the analysis result. In the Image Gallery, you use the arrow key to scroll through the particle images, to update the Edit View.

The Edit View is available with or without the option to inspect and retrieve particles in live mode, see Configuring the TCA Job Template by Switching the Active Branch.

If your color camera is Axiocam 705c, the default setting for live speed should be changed.

  1. In the Extended Camera tool > Mode section > Live Speed drop down list, select High Res.

    See Extended Camera Tool.

Particle Height Measurement

For measuring the height of particles, you select the particles and perform interactive measurement in the Particle Height Measurement view. The marked particles are saved in a table and stored in the archive. The report displays the three largest particles per type independent of the particle selection for height measurement. If a height measurement was conducted for these particles, the report shows the values for particle height in addition to length and width.

You have the following options for particle selection:

  • In advance: By configuration in the Standard Template Editor.
  • Additionally, within the workflow: In the Size Distribution (Live) view, you can manually mark or unmark desired particles in the Particle Gallery.
  • If desired, you can use both selection methods in combination or only one of them. Independent of the used selection method all particles are saved into one file.

Marking Particles for Height Measurement Automatically

  1. Select Standard Template Editor > Define Length Classes step > activate Automatic Particle Height Measurement.
  2. Two additional columns for particle height measurement are displayed per size class: one for metallic-shiny and the second for non shiny particles.
  3. Activate the desired particle size classes for height measurement.
  4. The automated selection of particles for interactive height measurement in the workflow is activated.

Particle Document

As an Operator, after running the job, you want to inspect the saved results of the Size Distribution view. This view is similar to the Size Distribution view, but without the acquisition and particle revision functionality.

Inspecting Results

  1. You have run a TCA job and saved it to the archive.
  2. You are in Browse Results mode.
  1. Select the Inspection-View-Document in the format .PADB and click .
  2. A view very similar to the Size Distribution view is displayed. The tools display statistical and approval information. You can use all filter functions.
  3. In the Image Gallery, select a particle and click the icon in the top right corner.
  4. The Inspection View view opens.
  5. In the Image Gallery, select the particle you want to inspect.
  6. The particle is centered in the view.
  7. You can zoom in and out to inspect the particle.
  8. When you have finished the inspection, click Close.

Interactive Particle Height Measurement View

The Interactive Particle Height Measurement view displays the particles that are intended for height measurement. In the Interactive Height Measurement workbench, in this view, you perform the height measurement.

Correcting Camera Offset

When using a TCA job template on a system with two cameras (AxioCam 705POL and a color camera, e.g. AxioCam 305c), there might be an offset between those cameras.

Example: Offset between AxioCam 705POL and color camera
Example: Offset between AxioCam 705POL and color camera

You check and correct the camera offset in the Edit View.

Note that you perform the offset correction on one particle and then the stage movement is corrected accordingly to the new coordinates for all particles. This applies only to the currently running job template. If you start the job template once more, you again need to correct the camera offset, because the offset settings are not saved.

  1. You are running a TCA job template in dual camera mode.
  2. You have acquired particle images.
  1. Go to the workflow step Size Distribution (Live), and in the Edit View check whether there is an offset between the two cameras.
  2. Here, you have the option to correct the offset. The Use Offset Correction checkbox is activated by default.
  3. Under Select Camera, select the color camera, and under Offset Correction, press Determine Offset.
  4. The Offset Correction mode is activated. The cursor changes to a cross.
  5. In Live View, click in the center of the particle whose stage coordinates you want to correct.
  6. The stage moves to the particle. The offset in displayed in µ in the Offset Correction control .
  7. If you are not satisfied with the result, click Reset

    and select the same particle again, or choose a more suitable one. Carry out the offset correction again.
  1. You have corrected the camera offset of the color camera. In the Position List with EDF workbench and in the Interactive Height Measurement workbench you can continue with your work with the stage set precisely. The new coordinates are also used here if you activate the color camera.
