From 9bb011e429c38807a16e1088bc838f0165c87bae Mon Sep 17 00:00:00 2001 From: panda <1415243231@qq.com> Date: Wed, 20 May 2026 23:43:16 +0800 Subject: [PATCH] feat: v4 multimodal chat input, multi-format support, and annotation detection - Replace st.chat_input with st-multimodal-chatinput (Ctrl+V paste, drag-drop, file button) - Extract _process_uploaded_file() shared handler (eliminates ~70 duplicated lines) - Add XLSX (openpyxl), XLS (xlrd), DOC (olefile) parsers to file_parser.py - Add backend/annotation_detector.py: circle detection (HoughCircles) + arrow detection (HoughLinesP clustering) + OCR correlation + LLM context formatting - Add annotation_result field to AgentState with session persistence - Wire annotation detection into process_input and _format_ocr_context - Add 11 new tests: 7 annotation detector + 4 multi-format parser - Update all docs: CLAUDE.md, README.md, CODE_GUIDE.md, ROADMAP.md --- CLAUDE.md | 48 ++++- CODE_GUIDE.md | 20 +- README.md | 18 +- ROADMAP.md | 40 +++- agent/nodes.py | 87 +++++++- agent/state.py | 3 + app.py | 266 ++++++++++++++++-------- backend/annotation_detector.py | 331 ++++++++++++++++++++++++++++++ backend/file_parser.py | 128 ++++++++++-- backend/layout_analyzer.py | 68 +++--- backend/ocr_extractor.py | 8 +- prompts/modification.md | 2 + requirements.txt | 18 ++ tests/test_annotation_detector.py | 151 ++++++++++++++ tests/test_e2e_ocr.py | 143 +++++++++++++ tests/test_file_parser_formats.py | 90 ++++++++ 16 files changed, 1257 insertions(+), 164 deletions(-) create mode 100644 backend/annotation_detector.py create mode 100644 tests/test_annotation_detector.py create mode 100644 tests/test_e2e_ocr.py create mode 100644 tests/test_file_parser_formats.py diff --git a/CLAUDE.md b/CLAUDE.md index 94bd19e..6a85d92 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -20,7 +20,7 @@ STREAMLIT_SERVER_HEADLESS=true streamlit run app.py --server.port 8501 ## 当前配置（.env） -- **OCR**: EasyOCR（优先，ch_sim+en）→ PaddleOCR（回退），两者均未安装时仅返回图片元信息 +- **OCR**: PaddleOCR（精确识别首选，ppocr-v4）→ EasyOCR（回退，ch_sim+en），两者均未安装时仅返回图片元信息 -
