During learning, be sure to pass the product name and not the PLU or barcode, as this may affect the algorithm's automatic optimization and lead to suboptimal recognition results!
After completing the activation steps, start the first Recognition.
Once recognition is complete, call the feedback interface to learn from the last recognized product.
After learning is complete, Recognition again to identify the product.

Recognition Nodes#

It is recommended to call the recognition interface after reaching the starting weight (suggested 20g, but this can be adjusted according to the situation), or you can use a delay to determine the recognition nodes as needed.
If you are concerned that the image may not be stable after reaching the starting weight, you can call the recognition interface again once the weight stabilizes.
Multiple recognitions can be called during a single weighing, but only one learning session is needed.
