+# PaddleDetection C Deployment Example
+
+This directory provides examples that `infer_xxx.c` fast finishes the deployment of PaddleDetection models, including PPYOLOE on CPU/GPU.
+
+Before deployment, two steps require confirmation
+
+- 1. Software and hardware should meet the requirements. Please refer to [FastDeploy Environment Requirements](../../../../../docs/en/build_and_install/download_prebuilt_libraries.md)  
+- 2.  Download the precompiled deployment library and samples code according to your development environment. Refer to [FastDeploy Precompiled Library](../../../../../docs/en/build_and_install/download_prebuilt_libraries.md)
+
+Taking inference on Linux as an example, the compilation test can be completed by executing the following command in this directory. FastDeploy version 1.0.4 or above (x.x.x>=1.0.4) is required to support this model.
+
+```bash
+ppyoloe is taken as an example for inference deployment
+
+mkdir build
+cd build
+# Download the FastDeploy precompiled library. Users can choose your appropriate version in the `FastDeploy Precompiled Library` mentioned above
+wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-x.x.x.tgz
+tar xvf fastdeploy-linux-x64-x.x.x.tgz
+cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-x.x.x
+make -j
+
+# Download the PPYOLOE model file and test images
+wget https://bj.bcebos.com/paddlehub/fastdeploy/ppyoloe_crn_l_300e_coco.tgz
+wget https://gitee.com/paddlepaddle/PaddleDetection/raw/release/2.4/demo/000000014439.jpg
+tar xvf ppyoloe_crn_l_300e_coco.tgz

+# GPU inference
+./infer_ppyoloe_demo ./ppyoloe_crn_l_300e_coco 000000014439.jpg 1
+```
+
+The above command works for Linux or MacOS. For SDK use-pattern in Windows, refer to:

+# PaddleDetection C 部署示例
+
+本目录下提供`infer_xxx.c`来调用C API快速完成PaddleDetection模型PPYOLOE在CPU/GPU上部署的示例。
+
+在部署前，需确认以下两个步骤
+
+- 1. 软硬件环境满足要求，参考[FastDeploy环境要求](../../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)  
+- 2. 根据开发环境，下载预编译部署库和samples代码，参考[FastDeploy预编译库](../../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)
+
+以Linux上推理为例，在本目录执行如下命令即可完成编译测试，支持此模型需保证FastDeploy版本1.0.4以上(x.x.x>=1.0.4)
+
+```bash
+以ppyoloe为例进行推理部署
+
+mkdir build
+cd build
+# 下载FastDeploy预编译库，用户可在上文提到的`FastDeploy预编译库`中自行选择合适的版本使用

 ## 模型转换example
 
-- [Picodet RKNPU2模型转换文档](./picodet.md)
-- [YOLOv8 RKNPU2模型转换文档](./yolov8.md)
+### 注意点
+
+PPDetection模型在RKNPU2上部署时要注意以下几点:
+
+* 模型导出需要包含Decode
+* 由于RKNPU2不支持NMS，因此输出节点必须裁剪至NMS之前
+* 由于RKNPU2 Div算子的限制，模型的输出节点需要裁剪至Div算子之前
+
+### Paddle模型转换为ONNX模型
+
+由于Rockchip提供的rknn-toolkit2工具暂时不支持Paddle模型直接导出为RKNN模型，因此需要先将Paddle模型导出为ONNX模型，再将ONNX模型转为RKNN模型。
+
+```bash
+# 以Picodet为例
+# 下载Paddle静态图模型并解压
+wget https://paddledet.bj.bcebos.com/deploy/Inference/picodet_s_416_coco_lcnet.tar
+tar xvf picodet_s_416_coco_lcnet.tar
+
+# 静态图转ONNX模型，注意，这里的save_file请和压缩包名对齐
+paddle2onnx --model_dir picodet_s_416_coco_lcnet \
+            --model_filename model.pdmodel \
+            --params_filename model.pdiparams \
+            --save_file picodet_s_416_coco_lcnet/picodet_s_416_coco_lcnet.onnx \
+            --enable_dev_version True
+
+# 固定shape
+python -m paddle2onnx.optimize --input_model picodet_s_416_coco_lcnet/picodet_s_416_coco_lcnet.onnx \
+                                --output_model picodet_s_416_coco_lcnet/picodet_s_416_coco_lcnet.onnx \
+                                --input_shape_dict "{'image':[1,3,416,416]}"
+```
+
+### 编写yaml文件
+
+**修改normalize参数**
+
+如果你需要在NPU上执行normalize操作，请根据你的模型配置normalize参数，例如:
+
+```yaml
+mean:
+  -
+    - 123.675
+    - 116.28
+    - 103.53
+std:
+  -
+    - 58.395
+    - 57.12
+    - 57.375
+```
+
+**修改outputs参数**
+由于Paddle2ONNX版本的不同，转换模型的输出节点名称也有所不同，请使用[Netron](https://netron.app)对模型进行可视化，并找到以下蓝色方框标记的NonMaxSuppression节点，红色方框的节点名称即为目标名称。
+
+例如，使用Netron可视化后，得到以下图片:
+
+![](https://user-images.githubusercontent.com/58363586/212599781-e1952da7-6eae-4951-8ca7-bab7e6940692.png)
+
+找到蓝色方框标记的NonMaxSuppression节点，可以看到红色方框标记的两个节点名称为p2o.Div.79和p2o.Concat.9,因此需要修改outputs参数，修改后如下:
+
+```yaml
+outputs_nodes:
+  - 'p2o.Mul.179'
+  - 'p2o.Concat.9'
+```
+
+### ONNX模型转RKNN模型
+
+为了方便大家使用，我们提供了python脚本，通过我们预配置的config文件，你将能够快速地转换ONNX模型到RKNN模型
+
+```bash
+python tools/rknpu2/export.py --config_path tools/rknpu2/config/picodet_s_416_coco_lcnet_unquantized.yaml \
+                              --target_platform rk3588
+```
