Software Navigation

• How do I access the OV20i software interface? Connect the camera via USB or Ethernet and enter the appropriate IP address in your web browser.
• What is the 'All Recipes' page? It's the home page where you can create, view, and manage all your recipes.
• What does the HMI section display? The HMI (Human-Machine Interface) shows live image results from the active recipe and allows manual camera triggering.
• What is the purpose of the Library section? The Library stores all images captured by the camera, which can be used for training datasets.
• What is the Haystack feature? Haystack provides visualization tools to analyze model trends and performance indicators.
• How can I update the OV20i software? Navigate to the Software Update section in the toolbar to upload and install updates.
• Where can I find system logs and settings? Under System Settings, you can view and edit network settings, system time, and device storage, and download system logs.
• How do I enable user profiles and permissions? Go to Users and Permissions in the toolbar to configure user access and roles.
• How can I access the user manual offline? Click on the User Manual section in the toolbar to download an offline copy of the manual.
• How do I contact Overview.ai support? Use the Overview Support section in the toolbar to send an email to support@overview.ai.

Recipe Creation & Training

• How do I create a new recipe? From the All Recipes page, click '+ New Recipe', enter a name, select the recipe type, and click OK.
• What are the types of recipes I can create? You can create Classification and Segmentation recipes.
• How do I configure imaging settings? In the Recipe Editor, click 'Configure Imaging' to adjust focus, exposure, gamma, and LED light patterns.
• What is the purpose of the Template Image and Alignment step? It allows you to capture a reference image and align the inspection area; you can also choose to skip this step.
• How do I set up the Inspection Region of Interest (ROI)? In the Inspection Setup, adjust the ROI box to focus on the specific area you want to analyze.
• How many images are needed for training a classification model? A minimum of 5 different images per class is recommended for effective training.
• What training options are available for classification models? You can choose between 'Fast' for quick testing and 'Accurate' for production use, adjusting iterations accordingly.
• How do I monitor training progress? A training progress modal displays the current iteration number and accuracy; you can abort or finish training early if needed.
• How do I view live results after training? Click 'Live Preview' in the Recipe Editor to see real-time classification results.
• Can I configure pass/fail logic for inspections? Yes, use the IO Block in the Recipe Editor to set up logic using Node-RED for pass/fail criteria.

Classification & Segmentation

• What is a Classification recipe used for? Classification recipes are used to categorize images into predefined classes based on visual features.
• What is a Segmentation recipe used for? Segmentation recipes identify and label specific regions within an image, useful for detecting defects or features.
• How do I train a Segmentation model? After setting up imaging and inspection, label the regions of interest and train the model using the provided tools.
• Can I use the same images for both Classification and Segmentation? Yes, images stored in the Library can be used for training both types of models.
• How do I evaluate model performance? After training, review the accuracy metrics and validation results provided in the software.
• Can I retrain a model with additional data? Yes, you can add more labeled images and retrain the model to improve accuracy.
• What is the purpose of the Confidence Threshold in classification? It sets the minimum confidence level required for a classification to be considered valid.
• How do I handle multiple ROIs in a single recipe? You can define multiple ROIs during the Inspection Setup and configure logic for each in the IO Block.
• Can I export trained models? The documentation does not specify model export functionality; contact support for more information.
• How do I delete or deactivate a recipe? In the All Recipes page, use the Actions menu next to the recipe to deactivate or delete it.

Advanced Features & Troubleshooting

• What is Node-RED in the context of OV20i? Node-RED is a flow-based development tool used within the OV20i software to configure inspection logic.
• How do I configure digital outputs for inspection results? Use the IO Block to assign outputs based on inspection results, setting conditions in Node-RED.
• What should I do if the camera is not connecting via Ethernet? Ensure your computer's IP settings are correct and that the Ethernet cable is properly connected; refer to the Electrical and Communication guide.
• How can I reset the OV20i camera? You can reset the camera via the System Settings in the software or by pressing the physical reset button on the device.
• What is the maximum current for digital outputs? Each digital output can sink up to 100mA when active.
• How do I prevent IP conflicts on my network? Assign unique static IP addresses to each device and use IP scanner tools to detect conflicts.
• Can I use the OV20i in high-temperature environments? Yes, but ensure proper mounting and ventilation; use front mounting points for better heat dissipation.
• What is the function of the 'Skip Aligner' option? It allows you to bypass the alignment step during recipe setup if alignment is not necessary for your application.
