+以下步骤均在Ubuntu电脑上完成，请参考配置文档完成转换模型环境配置。下面以Picodet-s为例子,教大家如何转换PaddleDetection模型到RKNN模型。
+

+```
+
+### 编写模型导出配置文件
+以转化RK3568的RKNN模型为例子，我们需要编辑tools/rknpu2/config/RK3568/picodet_s_416_coco_lcnet.yaml，来转换ONNX模型到RKNN模型。
+
+**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
+model_path: ./picodet_s_416_coco_lcnet/picodet_s_416_coco_lcnet.onnx
+output_folder: ./picodet_s_416_coco_lcnet
+target_platform: RK3568
+normalize:
+  mean: [[0.485,0.456,0.406],[0,0,0]]
+  std: [[0.229,0.224,0.225],[0.003921,0.003921]]
+outputs: ['tmp_17','p2o.Concat.9']
+```
+
+**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)，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/58363586/202728663-4af0b843-d012-4aeb-8a66-626b7b87ca69.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tmp_17和p2o.Concat.9,因此需要修改outputs参数，修改后如下:
+```yaml
+model_path: ./picodet_s_416_coco_lcnet/picodet_s_416_coco_lcnet.onnx
+output_folder: ./picodet_s_416_coco_lcnet
+target_platform: RK3568
+normalize: None
+outputs: ['tmp_17','p2o.Concat.9']
+```
+
+### 转换模型
+```bash
+
 # ONNX模型转RKNN模型
 # 转换模型,模型将生成在picodet_s_320_coco_lcnet_non_postprocess目录下
-python tools/rknpu2/export.py --config_path tools/rknpu2/config/RK3588/picodet_s_416_coco_lcnet.yaml
+python tools/rknpu2/export.py --config_path tools/rknpu2/config/RK3568/picodet_s_416_coco_lcnet.yaml
+```
+
+### 修改模型运行时的配置文件
+
+配置文件中，我们只需要修改**Preprocess**下的**Normalize**和**Permute**.
+
+**删除Permute**
+
+RKNPU只支持NHWC的输入格式，因此需要删除Permute操作.删除后，配置文件Precess部分后如下:
+```yaml
+Preprocess:
+- interp: 2
+  keep_ratio: false
+  target_size:
+  - 416
+  - 416
+  type: Resize
+- is_scale: true
+  mean:
+  - 0.485
+  - 0.456
+  - 0.406
+  std:
+  - 0.229
+  - 0.224
+  - 0.225
+  type: NormalizeImage
+```
+
+**根据模型转换文件决定是否删除Normalize**
+
+RKNPU支持使用NPU进行Normalize操作，如果你在导出模型时配置了Normalize参数，请删除**Normalize**.删除后配置文件Precess部分如下:
+```yaml
+Preprocess:
+- interp: 2
+  keep_ratio: false
+  target_size:
+  - 416
+  - 416
+  type: Resize
 ```
