Q & A
What is the purpose of the 'Auto Bear' system presented in the video?
-The 'Auto Bear' system is an AI-powered instant checkout system designed for smaller retail stores, using computer vision and deep learning to visually identify items placed on the countertop for a fast, contact-free self-checkout experience.
What materials are required to build the physical structure of the Auto Bear system?
-The project requires 15 mm thick plywood of specific dimensions, wood screws, a load cell, an amplifier module, a camera module, LED strips, a white acrylic sheet for the countertop, and a small rectangular box for the Raspberry Pi.
Why is sanding necessary before painting the cabinet?
-Sanding is necessary to create an even surface, which is essential for painting. It helps in adhering the paint properly and provides a smooth finish.
How is the load cell integrated into the Auto Bear system?
-The load cell is attached to the center of the base, with positions marked and holes drilled for connections. It is secured in place using nuts and bolts, and an amplifier module is soldered for coupling the load cell to the Raspberry Pi.
What role does the camera module play in the Auto Bear system?
-The camera module, along with artificial intelligence, is used for the visual identification of objects placed on the countertop. It is connected to the Raspberry Pi and positioned beneath the top side of the cabinet.
Why are LED strips used in the Auto Bear system?
-LED strips are used to provide better visibility even in low light conditions, illuminating the items placed on the countertop for accurate identification by the camera module.
How is the load cell calibrated in the Auto Bear system?
-The load cell is calibrated using standard weights or non-weights to ensure accurate measurements of the weight of objects placed on the countertop.
What platform is used for the object detection AI in the Auto Bear system?
-At gimbals is used as the development platform for machine learning on added devices, facilitating the training and deployment of the object detection AI.
How is the dataset for object detection prepared in the Auto Bear system?
-A dataset containing images of the objects to be detected is loaded and labeled, with the process of labeling being automated to some extent by At gimbals to decrease the time required.
What is the reported accuracy of the generated machine learning model for object detection?
-The generated machine learning model has an accuracy of 98.9%, which is considered quite good for object detection tasks.
How is the software for the Auto Bear system developed and where can the code be found?
-The software is written in Python, with the checkout page developed using Node.js. The code can be found in a GitHub repository, the link to which is provided in the video description.
