# PicoDet ONNX Runtime Demo
本文件夹提供利用[ONNX Runtime](https://onnxruntime.ai/docs/)进行 PicoDet 部署与Inference images 的 Demo。
## 安装 ONNX Runtime
本demo采用的是 ONNX Runtime 1.10.0，可直接运行如下指令安装：
```shell
pip install onnxruntime
```
详细安装步骤，可参考 [Install ONNX Runtime](https://onnxruntime.ai/docs/install/)。
## Inference images
- 准备测试模型：根据[PicoDet](https://github.com/PaddlePaddle/PaddleDetection/tree/develop/configs/picodet)中【导出及转换模型】步骤，采用包含后处理的方式导出模型（`-o export.benchmark=False` ），并生成待测试模型简化后的onnx模型（可在下文链接中直接下载）。同时在本目录下新建```onnx_file```文件夹，将导出的onnx模型放在该目录下。
- 准备测试所用图片：将待测试图片放在```./imgs```文件夹下，本demo已提供了两张测试图片。
- 在本目录下直接运行：
```shell
python infer_demo.py --modelpath ./onnx_file/picodet_s_320_lcnet_postprocessed.onnx
```
将会对```./imgs```文件夹下所有图片进行识别，并将识别结果保存在```./results```文件夹下。
- 结果：
<div align="center">
<img src="../../../docs/images/bus.jpg" height="300px" ><img src="../../../docs/images/dog.jpg" height="300px" >
</div>
