Creating a New Model#

On this page we will see how to create a reference model for component identification.

Step 1: Preparing the Physical Setup#

If not already done, follow these steps:

Remove the calibration grid and restore the initial layout:

Reposition the surface
reposition the central flange
secure the central flange with its four screws

Place an object in the centre of the vision area

Step 2: Access to the Model#

Once the physical preparation is complete, proceed with image capture and model creation

3	From the “Recipes” page, with the right recipe selected click
4	Select the FlexiBowl® you are working with FlexiBowl® Choice
5	The available model slots will be shown (up to 8 models per recipe)
6	Click Model 1 to access the “Train Model 1 Cam 1” page

Train Model interface overview#

Train Model page

Parameter	Function
Enable Model	Activates this model slot making it usable
Grab Train Image	Takes a picture of the reference component for training
Score Threshold	Adjusts the level of detail of the model (from 0 = maximum detail to 1 = minimum detail)
Train	Actually generates the model by processing the captured image
Model Name	Text field to assign a descriptive name to the model

Tip

Multiple model management

In this phase only the first model is activated. After completion, you may:

Enable additional slots (Model 2, Model 3, etc.) for different parts in the same recipe
Modify existing models
Disable models no longer required

For the time being, focus on completing the first model.

Step 3: Training Procedure#

7	Click Enable Model to enable this model. The model is now active and ready to be configured.
8	Click Grab Train Image to take a picture of the reference component we have placed on the FlexiBowl® Warning The reference component must remain stationary at that point throughout the application creation process
9	Move the ROI box to fully frame the component
10	Move the origin (reference point) to the centre of the frame area Tip Where to position the origin? The origin is automatically placed at the centre of the component. If the pick point does not coincide with the geometric centre, move the origin to the: Pick point: For asymmetric parts, position where the gripper grasps The origin defines the (0,0) point of the model coordinate system.
11	Use the Score Threshold to adjust the desired level of detail Note Score Threshold Value close to 0 → Detects MORE detail (more precise model) Value close to 1 → Detects LESS detail (simpler model) Tip How to choose the optimal Score Threshold? Use a LOW value (0.1-0.3) when: The part has many distinctive details (engravings, logos, texture) The parts are always very similar to one another (tight tolerances) Maximum precision is required even with difficult orientations Use a HIGH value (0.4-0.6) when: The part has a distinctive but simple shape A balance between precision and tolerance is desired First configuration of a model (starting point) Use a VERY HIGH value (0.7-0.9) when: There are significant variations between parts (wide tolerances) The part surface is highly reflective or variable
12	Click Train

Tip

If you have any doubts during configuration, please consult the INFO key on the current page.

Step 4: Visual inspection#

After generating the model, it is essential to check its quality before proceeding.

13	Zoom in on the image to inspect the details of the model created and verify that the model is correct Tip Valid Model Characteristics ✓ Have enough lines to recognise the component ✓ Do not include the texture of the background surface ✓ Avoid light reflections

Attention

If the model is not satisfactory:

Edit the Score Threshold
Click again on Train
Repeat until an ideal model is achieved

Tip

Optimisation strategy

Problem: Model includes surface texture → Solution: Increase Score Threshold or Cam Exposure value (SETUP > Camera Setup > Cam Exposure)

Problem: Model has too few lines, not distinguishable → Solution: Decrease Score Threshold

Problem: Model includes reflections → Solution: Increase Score Threshold or adjust camera exposure

Make gradual changes (steps of 0.1-0.2) and test each time.

Step 5: Save#

14	Name the model with a descriptive name Tip Avoid generic names ❌ Names to avoid: `Test`, `Prova`, `Modello1`, `Nuovo_Modello` ✓ Recommended names: `Prod_Viti_M8_Acciaio` `Assembly_Connettori_2024` `QC_Ingranaggi_Serie_X` A clear name makes it easier to manage when there are many different models.
