结论- 结合传统OCR（Tesseract）和QwenVL2.5的多模态能力
- OCR保证基础文字识别，QwenVL2.5进行语义理解和信息关联
- 图像尺寸标准化（1024x1024）
- 可选对比度增强模块（CLAHE算法）
- RGB色彩空间转换
- 基于正则表达式的模式匹配
- 支持中英文发票格式
- 金额数值化处理
- 关键字段包含：发票代码、号码、日期、金额、买卖方信息
- 专用提示词工程："请提取这张发票上的所有关键信息..."
- 图像-文本联合编码
- 生成式结果输出
- 可配置的正则表达式模式库
- 支持添加新发票类型模板
- 结果融合策略可扩展（权重分配、冲突解决）
性能优化建议： - 添加图像缓存机制
- 实现异步处理队列
- 部署模型量化版本（INT4）
- 收集特定领域发票数据微调QwenVL2.5
- 添加版面分析模块（检测表格区域）
- 实现字段级置信度评估
- 添加数据脱敏模块
- 实现分布式处理架构
- 集成审批工作流系统
该方案通过融合传统OCR技术和先进的多模态大模型，在保证基础识别能力的同时，利用QwenVL2.5的语义理解优势，可以更好地处理复杂版式发票和非常规字段提取需求。 |
