基于PaddleOCR重构，并且脱离PaddlePaddle深度学习训练框架的OCR.zip

# paddleocr模型转换成onnx模型后，利用ONNX模型进行推理 ## 1、安装paddle2onnx ```angular2html pip install paddle2onnx ``` ## 2、下载paddleocr模型文件 ```angular2html !wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_mobile_v2.0_cls_infer.tar !wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_server_v2.0_rec_infer.tar !wget https://paddleocr.bj.bcebos.com/dygraph_v2.0/ch/ch_ppocr_server_v2.0_det_infer.tar ``` ## 3、解压模型文件 ```angular2html !tar -xvf /home/aistudio/onnx_pred/models/ch_ppocr_mobile_v2.0_cls_infer.tar !tar -xvf /home/aistudio/onnx_pred/models/ch_ppocr_server_v2.0_det_infer.tar !tar -xvf /home/aistudio/onnx_pred/models/ch_ppocr_server_v2.0_rec_infer.tar ``` ## 4、将paddleocr模型转成onxx模型 ```angular2html paddle2onnx --model_dir ./ch_ppocr_server_v2.0_rec_infer \ --model_filename inference.pdmodel \ --params_filename inference.pdiparams \ --save_file ./ch_ppocr_server_v2.0_rec.onnx \ --opset_version 11 \ --enable_onnx_checker True paddle2onnx --model_dir ./ch_ppocr_server_v2.0_det_infer \ --model_filename inference.pdmodel \ --params_filename inference.pdiparams \ --save_file ./ch_ppocr_server_v2.0_det.onnx \ --opset_version 11 \ --enable_onnx_checker True paddle2onnx --model_dir ./ch_ppocr_mobile_v2.0_cls_infer \ --model_filename inference.pdmodel \ --params_filename inference.pdiparams \ --save_file ./ch_ppocr_mobile_v2.0_cls.onnx \ --opset_version 11 \ --enable_onnx_checker True ``` ## 5、安装onnx ```angular2html pip install onnx==1.14.0 pip install onnxruntime-gpu==1.14.1 ``` ## 6、模型推理 ```angular2html import cv2 model = ONNXPaddleOcr() img = cv2.imread('./1.jpg') # ocr识别结果 result = model.ocr(img) print(result) # 画box框 sav2Img(img, result) ```
