Getting started

install dependence

gcc version: 14

prepare opencv (at least version 4.2.0)

sudo apt-get install libopencv-dev

prepare onnxruntime

visit onnxruntime release and download proper version.

build demo with bash followed

ORT_HOME=${PATH_TO_ONNXRUNTIME}
# Note: Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
# "OpenCV_DIR" to a directory containing one of the following names:
#   OpenCVConfig.cmake
#   opencv-config.cmake
OPENCV_DIR=${PATH_TO_OPENCV_CMAKE_DIR}

mkdir build && pushd build
cmake .. -DORT_HOME=${ORT_HOME} -DOpenCV_DIR=${OPENCV_DIR} -DCMAKE_BUILD_TYPE=Debug -DTEST=OFF -DDEMO=ON
make install -j`nproc`
popd

# Or with cross compiler:
CROSS_TOOL=${PATH_TO_COMPILER_PREFIX}-
SYSROOT=${PATH_TO_SYSROOT}
cmake .. -DORT_HOME=${ORT_HOME} -DOpenCV_DIR=${OPENCV_DIR} \
   -DCMAKE_C_COMPILER=${CROSS_TOOL}gcc -DCMAKE_CXX_COMPILER=${CROSS_TOOL}g++ -DCMAKE_SYSROOT=${SYSROOT}

Using environment variables to implement functions

Environment variable name	Remarks
SUPPORT_SHOW (stream demo)	-1 means not to display
SUPPORT_SHOWFPS (stream demo)	If there is content, fps will be displayed
SUPPORT_PROFILING_PROJECTS	Generated profile file address
SUPPORT_LOG_LEVEL	The range is 0-4
SUPPORT_GRAPH_OPTIMIZATION_LEVEL	Graph optimization level (ort_disable_all, ort_enable_basic, ort_enable_extended, ort_enable_all)
SUPPORT_OPT_MODEL_PATH	Optimized model path
SUPPORT_DISABLE_SPACEMIT_EP	1 means to disable spacemit-ep
SUPPORT_OPENCV_THREAD_NUM	The number of threads used by opencv(>= 4.x)

Description of formats related to label files, configuration files, and model files

Model files format: ONNX(Open Neural Network Exchange)

label files format: using text document, here is a recommended example

configuration files format: using json, the recommended configuration file content is as here
