目录1. 新建文件夹2. 准备数据3. 数据集的划分注意1注意24. 下载预训练模型5. 训练文字检测模型6. 训练文字识别模型7. 测试8. 转换为推理模型9. 检测模型和识别模型推理1. 新建文件夹进入PPOCRLabel源码目录在上一层目录新建文件夹train_data在train_data中新建文件夹drivingData。2. 准备数据在PPOCRLabel中标注好的数据如下图将标注好的数据拷贝到drivingData文件夹。3. 数据集的划分cd到PPOCRLabel源码路径运行划分数据集代码python gen_ocr_train_val_test.py--trainValTestRatio6:2:2--datasetRootPath../train_data/drivingData会在train_data文件夹下出现如下文件夹可删除drivingData文件夹。注意1新版本gen_ocr_train_val_test.py中做了操作系统兼容处理在linux下不会报错代码如下部分代码withopen(label_file_path,r,encodingUTF-8)aslabel_file:label_file_contentlabel_file.readlines()random.shuffle(label_file_content)label_record_lenlen(label_file_content)forindex,label_record_infoinenumerate(label_file_content):image_relative_path,image_labellabel_record_info.split(\t)image_nameos.path.basename(image_relative_path)ifflagdet:image_pathos.path.join(data_abs_path,image_name)elifflagrec:image_pathos.path.join(data_abs_path,args.recImageDirName,image_name)老版本gen_ocr_train_val_test.py中labelFileReadopen(labelFilePath,r,encodingUTF-8)labelFileContentlabelFileRead.readlines()random.shuffle(labelFileContent)labelRecordLenlen(labelFileContent)forindex,labelRecordInfoinenumerate(labelFileContent):imageRelativePathlabelRecordInfo.split(\t)[0]imageLabellabelRecordInfo.split(\t)[1]imageNameos.path.basename(imageRelativePath)ifflagdet:imagePathos.path.join(dataAbsPath,imageName)elifflagrec:imagePathos.path.join(dataAbsPath,{}\\{}.format(args.recImageDirName,imageName))在windows下使用以上代码在linux下将上面代码最后一行的“{}\{}”改为“{}/{}”。注意2如果是在云端AutoDL上进行训练建议在云端linux进行上面的数据划分代码如果在windows下划分的数据集路径为如下格式训练要在云端需要改路径D:\项目\train_data\det\train\2026_6_18_11_22_25_Digital.jpg[{transcription:23.6,points:[[287,152],[509,152],[509,277],[287,277]],difficult:false},{transcription:89,points:[[369,271],[505,271],[505,401],[369,401]],difficult:false}]D:\项目\train_data\det\train\2026_6_16_16_25_30_Digital.jpg[{transcription:21.5,points:[[300,197],[480,197],[480,283],[300,283]],difficult:false},{transcription:41.9,points:[[280,278],[485,278],[485,372],[280,372]],difficult:false}]D:\项目\train_data\det\train\2026_6_17_15_29_20_Digital.jpg[{transcription:20.2,points:[[305,154],[507,154],[507,280],[305,280]],difficult:false},{transcription:56,points:[[373,271],[502,271],[502,400],[373,400]],difficult:false}]train.txt文件中D:\项目\train_data\det\train替换/root/PaddleOCR/PaddleOCR-main/train_data/det/train/val.txt替换/root/PaddleOCR/PaddleOCR-main/train_data/det/val/test.txt替换/root/PaddleOCR/PaddleOCR-main/train_data/det/test/#rec文件夹也类似替换。4. 下载预训练模型模型列表将下载的预训练模型放在如下文件夹下5. 训练文字检测模型打开如下文件做如下修改Global: model_name: PP-OCRv5_server_det# To use static model for inference.debug:falseuse_gpu:trueepoch_num:epoch_num500log_smooth_window:20print_batch_step:10save_model_dir: /root/autodl-fs/output-1/PP-OCRv5_server_det save_epoch_step:10eval_batch_step: -0-200cal_metric_during_train:falsecheckpoints: pretrained_model: /root/PaddleOCR/PaddleOCR-main/pretrain_models/PP-OCRv5_server_det_pretrained.pdparams save_inference_dir: null use_visualdl:falseinfer_img: doc/imgs_en/img_10.jpg save_res_path: ./checkpoints/det_db/predicts_db.txt distributed:trueArchitecture: model_type: det algorithm: DB Transform: null Backbone: name: PPHGNetV2_B4 det: True Neck: name: LKPAN out_channels:256intracl:trueHead: name: PFHeadLocal k:50mode:largeLoss: name: DBLoss balance_loss:truemain_loss_type: DiceLoss alpha:5beta:10ohem_ratio:3Optimizer: name: Adam beta1:0.9beta2:0.999lr: name: Cosine learning_rate:0.001#(8*8c)warmup_epoch:2regularizer: name: L2 factor: 1e-6 PostProcess: name: DBPostProcess thresh:0.3box_thresh:0.6max_candidates:1000unclip_ratio:1.5Metric: name: DetMetric main_indicator: hmean Train: dataset: name: SimpleDataSet data_dir: /root/PaddleOCR/PaddleOCR-main/train_data label_file_list: -
