/**

|
|
* @short_description: Detect objects in video frame
|
|
*
|
|
* This element can apply a generic ONNX object detection model such as YOLO or SSD
|
|
* to each video frame.
|
|
*
|
|
* To install ONNX on your system, recursively clone this repository
|
|
* https://github.com/microsoft/onnxruntime.git
|
|
*
|
|
* and build and install with cmake:
|
|
*
|
|
* CPU:
|
|
*
|
|
* cmake -Donnxruntime_BUILD_SHARED_LIB:ON -DBUILD_TESTING:OFF \
|
|
* $SRC_DIR/onnxruntime/cmake && make -j8 && sudo make install
|
|
*
|
|
*
|
|
* GPU :
|
|
*
|
|
* cmake -Donnxruntime_BUILD_SHARED_LIB:ON -DBUILD_TESTING:OFF -Donnxruntime_USE_CUDA:ON \
|
|
* -Donnxruntime_CUDA_HOME=$CUDA_PATH -Donnxruntime_CUDNN_HOME=$CUDA_PATH \
|
|
* $SRC_DIR/onnxruntime/cmake && make -j8 && sudo make install
|
|
*
|
|
*
|
|
* where :
|
|
*
|
|
* 1. $SRC_DIR and $BUILD_DIR are local source and build directories
|
|
* 2. To run with CUDA, both CUDA and cuDNN libraries must be installed.
|
|
* $CUDA_PATH is an environment variable set to the CUDA root path.
|
|
* On Linux, it would be /usr/local/cuda-XX.X where XX.X is the installed version of CUDA.
|
|
*
|
|
*
|
|
* ## Example launch command:
|
|
*
|
|
* (note: an object detection model has 3 or 4 output nodes, but there is no
|
|
* naming convention to indicate which node outputs the bounding box, which
|
|
* node outputs the label, etc. So, the `onnxobjectdetector` element has
|
|
* properties to map each node's functionality to its respective node index in
|
|
* the specified model. Image resolution also need to be adapted to the model.
|
|
* The videoscale in the pipeline below will scale the image, using padding if
|
|
* required, to 640x383 resolution required by the model.)
|
|
*
|
|
* model.onnx can be found here:
|
|
* https://github.com/zoq/onnx-runtime-examples/raw/main/data/models/model.onnx
