PPOCRv3 Python部署示例

在部署前，需确认以下两个步骤

本目录下提供infer.py快速完成PPOCRv3在CPU/GPU，以及GPU上通过TensorRT加速部署的示例。执行如下脚本即可完成

                --image 12.jpg \
                --device cpu

# NPU推理
python3 infer_static_shape.py \
                --det_model ./ch_PP-OCRv3_det_infer/ch_PP-OCRv3_det_infer_rk3588_unquantized.rknn \

                --device npu

运行完成可视化结果如下图所示
