# QRCode_det

This version of QRCode detetion model has been converted to run on the Axera NPU using **w8a16** quantization.

This model has been optimized with the following LoRA: 

Compatible with Pulsar2 version: 5.1

## Convert tools links:

For those who are interested in model conversion, you can try to export axmodel through 

- [The original repo](https://github.com/wzf19947/QRCode_det), which you can get the detail of guide

- [Pulsar2 Link, How to Convert ONNX to axmodel](https://pulsar2-docs.readthedocs.io/en/latest/pulsar2/introduction.html) 

- [The repo of AXera Platform](https://github.com/AXERA-TECH/ax-samples),which you can learn how to compile the C++ demo
