AI can only detect products that have reference images. If a product is missing reference images, it may be misclassified or not recognized at all.

How to capture reference images

To ensure accurate product recognition, follow these steps to capture your reference images:

1. Access the AI Training page in the Settings section

2. Select the product from your inventory: Find the item you want to add reference images to. You can browse through the categories or use the search bar.

3. Place the item on the kiosk base and wait for the camera button to turn green. Capture the reference images by pressing the green capture button

• Keep only one item at a time 
• Keep surrounding areas clear 
• The capture button will only turn green if the AI sees a single product in the frame

When to capture reference images?

• For all new products or variations
• For daily changing items (e.g., freshly prepared meals)

Product type overview

1. Retail items 

Flat items (e.g., chocolate bars, muesli bars, chips, bagged snacks) 

• Take at least 5–8 images of each item.
• Rotate the item and photograph it from different angles: horizontal, vertical, tilted right, tilted left.
• Turn the item around and photograph the back as well, again capturing multiple angles.

Boxy items (e.g., juice boxes, cookie boxes, or anything rectangle)

• Take at least 4 images of all the different sides: standing upright, laid flat, and at different angles. This means 4 x 4 images, so at least 16 in total.
• Remember, these products can be placed on the kiosk base in many different ways by the customer — capture each possible position.

Canned and bottled drinks

• Take at least 5–8 images of each canned drink.
• While the upright position is the most common, also take a few photos of the can/bottle laid down.
• Move the can/bottle around on the kiosk base so the camera can capture different sides and angles.
• Rotate the can/bottle between shots to show all sides to the camera.

CPG items with similar top- side appearance

For CPG items that look similar when viewed from above, it is recommended to follow a slightly different method for reference photos.

• Position the object in four locations: one in the center and three evenly spaced along the front edge of the tray
• For the side view of the item, position it directly beneath the top camera: take reference photos by rotating the item six times to complete a full 360-degree turn.
• To capture the top view of the item, position it in three distinct sections of the tray, as demonstrated in the animation. Rotate the items six times, covering a full 360 degrees, just like similarly to capturing the side view.

Sandwiches and other items

• Take at least 5–8 images of each item.
• Rotate the item and capture it from various angles: horizontal, vertical, tilted right, and tilted left, capture the front and back sides.
• Move the item around the kiosk base to capture it from multiple perspectives

Dot code items

• If you sell items with dot code stickers, make sure to capture images with the dot code stickers visibly placed on top of them.

2. Plated Meals

• Take 5–8 images of each plated dish.
• Use the same plate you plan to serve on for best recognition accuracy and follow the plating style and alignment you will use during actual service.
• Separate the components slightly so each item is clearly visible.
• Rotate the plate between shots to capture different angles.
• Gently shake the plate to show natural food movement.
• If the meal comes with optional toppings, take a couple of photos with the toppings added (you can place them all on one dish).
