Create a New Model#

This page explains how to create a reference model for component recognition.

Step 1: Physical setup preparation#

Remove the calibration grid and restore the initial layout:

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

Position one object at the center of the viewing area

Step 2: Access the model#

Once physical preparation is complete, proceed with image acquisition and model creation.

3	From the Recipes page, with the correct recipe selected, click Edit Recipe
4	Select the FlexiBowl currently in use
5	The available model slots will be shown, up to 8 models per recipe
6	Click Model 1 to open the Train Model 1 Cam 1 page

Train Model interface overview#

Train Model page

Parameter	Function
Enable Model	Activates this model slot and makes it usable
Grab Train Image	Captures a photo of the reference component for training
Score Threshold	Adjusts the model detail level, from 0 for maximum detail to 1 for minimum detail
Train	Generates the model by processing the acquired image
Model Name	Text field used to assign a descriptive name to the model

Tip

Managing multiple models

At this stage only the first model is activated. After completing it, it will be possible to:

Enable additional slots, Model 2, Model 3, and so on, for different parts inside the same recipe
Modify existing models
Disable models that are no longer required

For now, focus on completing the first model.

Step 3: Training procedure#

7	Click Enable Model to activate this model. The model is now active and ready to be configured.
8	Click Grab Train Image to capture a photo of the reference component positioned on the FlexiBowl Warning The reference component must remain fixed in that position throughout the entire application creation process.
9	Move the ROI box so that it fully frames the component
10	Move the origin reference point to the center of the ROI area Tip Where should the origin be placed? The origin is automatically placed at the center of the component. If the pick point does not match the geometric center, move the origin to the: Pick point: for asymmetric parts, place it where the gripper actually grasps the part The origin defines point (0,0) of the model coordinate system.
11	Use Score Threshold to adjust the desired detail level Note Score Threshold Value close to 0 -> detects MORE details, resulting in a more precise model Value close to 1 -> detects FEWER details, resulting in a 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 such as engravings, logos, or texture Parts are always very similar to each other, with tight tolerances Maximum precision is required even with difficult orientations Use a MEDIUM value, 0.4-0.6, when: The part has a distinctive but simple shape A balance between precision and tolerance is desired It is the first configuration of a model and a good starting point is needed Use a VERY HIGH value, 0.7-0.9, when: Significant part-to-part variations are present, with wide tolerances The part surface is highly reflective or variable
12	Click Train

Step 4: Visual check#

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

13	Zoom into the image to inspect the created model in detail and verify that it is correct Tip Characteristics of a valid model ✓ It contains enough lines to recognize the component ✓ It does not include the texture of the background surface ✓ It avoids light reflections

Attention

If the model is not satisfactory:

Modify the Score Threshold
Click Train again
Repeat until the model is optimal

Tip

Optimization strategy

Problem: model includes background surface texture
-> Solution: increase Score Threshold or increase the Cam Exposure value in SETUP > Camera Setup > Cam Exposure

Problem: model has too few lines and is not distinctive enough
-> Solution: decrease Score Threshold

Problem: model includes reflections
-> Solution: increase Score Threshold or adjust camera exposure

Apply gradual changes, typically 0.1 to 0.2 steps, and test every time.

Step 5: Saving#

14	Name the model with a descriptive name Tip Avoid generic names ❌ Names to avoid: `Test` `Trial` `Model1` `New_Model` ✓ Recommended names: `Prod_M8_Steel_Screws` `Assembly_Connectors_2024` `QC_Gears_Series_X` A clear name makes management easier when many different models are available.
