This fold provides PicoDet inference code using Intel's OpenVINO Toolkit. Most of the implements in this fold are same as demo_ncnn.
Recommand to use the xxx.tar.gz file to install instead of github method, link.

Install OpenVINO Toolkit

Go to OpenVINO HomePage

Download a suitable version and install.

Follow the official Get Started Guides: https://docs.openvinotoolkit.org/latest/get_started_guides.html

Set the Environment Variables

Windows:

Run this command in cmd. (Every time before using OpenVINO)

<INSTSLL_DIR>\openvino_2021\bin\setupvars.bat

Or set the system environment variables once for all:

Name	Value
INTEL_OPENVINO_DIR	<INSTSLL_DIR>\openvino_2021
INTEL_CVSDK_DIR	%INTEL_OPENVINO_DIR%
InferenceEngine_DIR	%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\share
HDDL_INSTALL_DIR	%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\external\hddl
ngraph_DIR	%INTEL_OPENVINO_DIR%\deployment_tools\ngraph\cmake

And add this to Path

%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\bin\intel64\Debug;%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\bin\intel64\Release;%HDDL_INSTALL_DIR%\bin;%INTEL_OPENVINO_DIR%\deployment_tools\inference_engine\external\tbb\bin;%INTEL_OPENVINO_DIR%\deployment_tools\ngraph\lib

Linux

Run this command in shell. (Every time before using OpenVINO)

source /opt/intel/openvino_2021/bin/setupvars.sh

Or edit .bashrc

vi ~/.bashrc

Add this line to the end of the file

source /opt/intel/openvino_2021/bin/setupvars.sh

Convert model

Convert to OpenVINO

cd <INSTSLL_DIR>/openvino_2021/deployment_tools/model_optimizer

Install requirements for convert tool

cd ./install_prerequisites
sudo install_prerequisites_onnx.sh

Then convert model. Notice: mean_values and scale_values should be the same with your training settings in YAML config file.

python3 mo_onnx.py --input_model <ONNX_MODEL> --mean_values [103.53,116.28,123.675] --scale_values [57.375,57.12,58.395]

Build

Windows

<OPENVINO_INSTSLL_DIR>\openvino_2021\bin\setupvars.bat
mkdir -p build
cd build
cmake ..
msbuild picodet_demo.vcxproj /p:configuration=release /p:platform=x64

Linux

source /opt/intel/openvino_2021/bin/setupvars.sh
mkdir build
cd build
cmake ..
make

Run demo

Download PicoDet openvino model PicoDet openvino model download link.

move picodet openvino model files to the demo's weight folder.

Edit file

step1:
main.cpp
#define image_size 416
...
auto detector = PicoDet("../weight/picodet_m_416.xml");
...
step2:
picodet_openvino.h
#define image_size 416
