PPOCRv3 C++ multi-thread Deployment Example

This directory provides examples file multi_thread_ocr.cc to fast deploy PPOCRv3 on CPU/GPU and GPU accelerated by TensorRT.

Two steps before deployment

Taking the PPOCRv3 inference on Linux as an example, the compilation test can be completed by executing the following command in this directory. FastDeploy version 0.7.0 or above (x.x.x>=0.7.0) is required to support this model.

mkdir build
cd build
# Download the FastDeploy precompiled library. Users can choose your appropriate version in the `FastDeploy Precompiled Library` mentioned above
wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-x.x.x.tgz
tar xvf fastdeploy-linux-x64-x.x.x.tgz
cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-x.x.x
make -j

The above command works for Linux or MacOS. For SDK in Windows, refer to:
- [How to use FastDeploy C++ SDK in Windows](../../../docs/cn/faq/use_sdk_on_windows.md)

The result returned after running is as follows
