【图片自动识别改名】识别图片中的文字并批量改名的工具，根据文字对图片批量改名，基于QT和腾讯OCR识别的实现方案

现在的工作单位经常搞一些意义不明的绩效工作，每个月都搞来一万多张图片让我们挨个打开对应图片上的名字进行改名操作以方便公司领导进行检查和搜索调阅，图片上面的内容有数字和文字，数字没有特殊意义不做识别，文字有手写的和手机后加的水印字体两种，主要的需求就是想批量识别图片上的文字并同时进行批量改名，在数字化办公、档案管理、摄影工作流等场景中，经常需要对大量图片文件进行命名。例如：

• 教育领域：批量识别试卷、作业照片中的标题或学号
• 医疗领域：识别 X 光片、病理报告图片中的患者信息
• 电商行业：自动提取商品图片中的 SKU、型号等信息
• 档案管理：将纸质文档扫描件按内容命名归档

通过 OCR 技术自动识别图片文字并批量改名，可以极大提高工作效率，减少人工错误。

界面设计

基于 Qt 的界面设计可以包含以下核心组件：

1. 文件选择区：包含 "添加图片" 和 "清空列表" 按钮，以及文件拖放功能
2. 图片预览区：网格布局展示待处理图片缩略图，支持选中操作
3. OCR 识别设置区：
   • 腾讯云 API 密钥输入框（SecretId/SecretKey）
   • 识别语言选择下拉框
   • 识别模式选择（通用文字 / 表格 / 手写体等）
4. 预览和操作区：
   • 原文件名与识别结果对比列表
   • 自定义命名规则设置（前缀、后缀、编号格式等）
   • "预览重命名" 和 "执行重命名" 按钮
5. 状态栏：显示处理进度、成功 / 失败数量和日志信息

代码说明

上述代码实现了一个完整的图片 OCR 批量改名工具，主要包含以下模块：

1. OCR 处理模块：

   • 使用腾讯云 OCR SDK 实现文字识别
   • 支持多种 OCR 类型（通用、高精度、手写体等）
   • 单独线程处理 OCR 请求，避免 UI 卡顿

2. 文件管理模块：

   • 支持文件选择和拖放
   • 图片预览网格布局
   • 文件批量重命名功能

3. UI 界面模块：

   • 采用 PyQt5 构建现代界面
   • 多区域布局设计，功能分区明确
   • 重命名规则自定义设置

4. 多线程处理：

   • OCR 识别线程
   • 文件重命名线程
   • 进度显示和状态更新

优化建议

1. 性能优化：

   • 实现 OCR 结果缓存机制，避免重复识别
   • 支持多线程并行 OCR 处理（需注意 API 调用频率限制）
   • 大图片预处理（缩放、压缩）减少 OCR 处理时间

2. 功能增强：

   • 添加文件过滤和排序功能
   • 支持正则表达式替换
   • 添加预览图片放大查看功能
   • 增加更多 OCR 识别选项（如表格识别、车牌识别等）

3. 用户体验：

   • 实现撤销 / 重做功能
   • 添加配置保存和加载功能
   • 支持拖放调整文件处理顺序
   • 增强错误处理和提示信息

4. 安全性：

   • 实现 API 密钥加密存储
   • 添加操作确认和恢复机制
   • 实现文件备份功能，防止误操作

这个工具可以显著提高需要处理大量图片命名工作的效率，特别是在需要基于图片内容进行命名的场景中。通过合理的优化，可以进一步提升其性能和用户体验。
