Digital Meter Reader with Grove - Vision AI
This tutorial will demonstrate the development process of digital meter reader using SSCMA based on Grove - Vision AI module.
Before starting, we recommend that you should read Grove - Deploy first.
Please refer to Grove - Deploy - Prerequisites.
The meter reading feature is based on the SWIFT-YOLO model, in this step you need a SWIFT-YOLO model weight with the suffix
.pth, you have two ways to get the model weight.
Download the pre-trained model from our Model Zoo.
Since the trained model is not suitable for running directly on edge computing devices, we need to export it to a TFLite format with a
.tflite suffix, and you have two ways to get the exported model (with model weights contained).
Download the exported TFLite model from our Model Zoo.
Refer to Export - PyTorch to TFLite to convert the SWIFT-YOLO model from PyTorch format to TFLite format by yourself.
This is the last and most important step to complete the meter reading, in this step you need to compile and flash the firmware to the Grove - Vision AI modules. Please refer to Grove - Deployment - Compile and Deploy to complete the deployment of the model.
After completing the Grove - Deployment Tutorial - Compile and Deploy - Deployment Routines, you need to open Grove Vision AI Console.
The above steps are graphically indicated in the console, and finally, you can see the real-time meter reading results as shown in the figure below.
