Build a shelf monitoring application using AWS Panorama

Out-of-stock (OOS) is an essential metric tracked throughout the retail industry. Brick-and-mortar retailers seek to reduce their expenses connected with OOS products, while concurrently increasing consumer fulfillment without inventory surplus.
A product can be OOS in three primary methods: Distribution OOS, Store OOS, and Shelf OOS. Shelf OOS takes place when there is stock in the store, however the product isnt on the shelf. With device learning (ML) and computer vision (CV) applications, merchants can improve on-shelf product availability, boost sales earnings, and enhance shopper fulfillment.
AWS Panorama is a CV and ML device and software application development kit (SDK) that allows you to include CV applications at the edge, where web bandwidth is limited, low latency is required, and data privacy is required. AWS Panorama provides you the capability to include CV to your existing Internet Protocol (IP) cams and automate tasks that traditionally need human assessment and tracking.
In this post, we walk you through the actions to construct a rack monitoring application with AWS Panorama to monitor on-shelf schedule of bottles and inform the shop manager when the count of an item on the rack goes below a particular limit. A basic interface enables shop managers to check on stock amounts and alter notice settings for OOS concerns.
The following image reveals an example of this application.

Requirements
For this walkthrough, you require the following hardware devices:

Service overview
The following diagram shows the architecture of our service.

AWS Panorama Appliance.
An IP cam with RTSP assistance with H. 264 video compression. For demonstration purposes, we utilize a JideTech IP Camera. Note that we dont endorse this specific device; numerous IP cameras are suitable with AWS Panorama.

The workflow of the service is as follows:

An IP cam deployed in the shop keeps track of the shelf and streams video to the AWS Panorama Appliance. An application and a pre-trained ML model deployed to the AWS Panorama Appliance process the video frames from the IP video camera.
Images from AWS Panorama processing are stored in an Amazon Simple Storage Service (Amazon S3) bucket.
A JSON message that includes details on how many bottles remain in the frame and referral to the frame place in Amazon S3 is taken into an Amazon Simple Queue Service (Amazon SQS) queue for more processing.
Amazon SQS activates an AWS Lambda function as messages get here. The function uses the data in the messages from the queue and calls a GraphQL API hosted on AWS AppSync.
AWS AppSync carries out 2 actions in this action:

Shop managers can change the threshold value of an item from the UI. Modifications to the limit worth from the UI are updated and stored by AWS AppSync and DynamoDB.

The function figures out whether the bottle count altered, and it compares the new bottle count with the limit worth set by a store supervisor. The function sends an e-mail and SMS notification to the store manager by means of Amazon Simple Notification Service (Amazon SNS) if the number of bottles is less than or equivalent to the limit worth.

AWS Amplify develops and hosts the front end of the shelf monitoring interface (UI). The front-end UI subscribes to the backend AWS AppSync anomalies, which updates the UI with the rack images and bottle counts automatically.

To deploy the option, you complete the following high-level steps:

Get a personal gain access to token from GitHub
Shop your token in AWS Secrets Manager.
Release AWS resources utilizing an AWS CloudFormation template.
Configure your AWS Panorama Appliance.
