ax650使用ax-pipeline进行推理

##搭建交叉编译环境

• 拉取ax-pipeline源码及子模块

git clone --recursive https://github.com/AXERA-TECH/ax-pipeline.git

• 下载sdk

cd ax-pipeline
./download_ax_bsp.sh ax650
cd ax650n_bsp_sdk
wget https://github.com/ZHEQIUSHUI/assets/releases/download/ax650/drm.zip
mkdir third-party
unzip drm.zip -d third-party
cd ..

• 下载opencv

mkdir 3rdparty
cd 3rdparty
wget https://github.com/ZHEQIUSHUI/assets/releases/download/ax650/libopencv-4.5.5-aarch64.zip
unzip libopencv-4.5.5-aarch64.zip

• 编译环境

wget https://developer.arm.com/-/media/Files/downloads/gnu-a/9.2-2019.12/binrel/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz
tar -xvf gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu.tar.xz
export PATH=$PATH:$PWD/gcc-arm-9.2-2019.12-x86_64-aarch64-none-linux-gnu/bin/

• 源码编译

cd ax-pipeline
mkdir build
cd build
cmake -DAXERA_TARGET_CHIP=AX650 -DBSP_MSP_DIR=$PWD/../ax650n_bsp_sdk/msp/out -DOpenCV_DIR=$PWD/../3rdparty/libopencv-4.5.5-aarch64/lib/cmake/opencv4 -DSIPY_BUILD=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=../toolchains/aarch64-none-linux-gnu.toolchain.cmake -DCMAKE_INSTALL_PREFIX=install ..
make -j12
make install

• 获得bin文件到开发板上

• 开发板运行

修改yolov5s.json文件
博主的

{"MODEL_TYPE": "MT_DET_YOLOV5","MODEL_PATH": "/root/Desktop/install/bin/config/models/yolov5s_hat.axmodel","TRACK_ENABLE": true,"STRIDES": [8, 16, 32],"ANCHORS": [10.0,13.0,16.0,30.0,33.0,23.0,30.0,61.0,62.0,45.0,59.0,119.0,116.0,90.0,156.0,198.0,373.0,326.0],"CLASS_NAMES": ["hat","person"],"CLASS_NUM": 2,"NMS_THRESHOLD": 0.44999998807907104,"PROB_THRESHOLD": 0.4000000059604645
}

需要修改标签和标签数量，anchors可以不改，如果你是官方模型pt训练的，然后修改一下模型路径

要显示推理到hdmi上，先杀掉 fb_vo 这个进程
ps aux|grep fb_vo
找到进程号后kill -9 实际pid杀掉即可
将hdmi插入hdmi0（远离网口的那个）
如果需要恢复运行/root/runVoHook.sh即可恢复原样

本例子使用读取视频MP4，调用npu推理到hdmi显示

./sample_demux_ivps_npu_hdmi_vo -p config/yolov5s.json -f test.mp4

开发板运行显示hdmi上的视频：
