黄仁欢 5a493b8d67 feat(seal): fix seal text extraction for edge cases 
- Add extent limit (max 350°) to prevent polar unwarp distortion
- Add polygon count check (<3 polygons → use PaddleOCRVL backup)
- Add imwrite_safe() to handle Chinese paths on Windows
- Add --pdf-names parameter for targeted debugging

Fixes issue where seal extraction returned empty string when:
- Arc extent exceeded 360° causing severe image distortion
- Too few text polygons detected leading to inaccurate arc calculation

Test results:
- Before: 0% similarity (empty string)
- After: 52.4% similarity (partial extraction)

Report Detection Backend

Java-based backend system for automated report validation and comparison using OCR.

Technology Stack

  • Core: Java 8 (Spring Boot 2.7.18)
  • Security: Sa-Token (RBAC, Session Management)
  • OCR Engine: PaddleOCR (via DJL - Deep Java Library)
  • Database: PostgreSQL (with Dynamic Datasource support)
  • Build Tool: Maven

Features

  • RBAC Implementation: Multi-role support (ADMIN, AUDITOR, USER) with uppercase standardization.
  • Sa-Token Security: Annotation-based permission checks and secure login.
  • Auditor Context Switch: Specialized feature for Auditors to switch between institutional views.
  • PDF Processing: Automatic conversion of PDF reports to images for OCR analysis.
  • Automated Verification: Integration tests using H2 in-memory database.

Getting Started

Prerequisites

  • JDK 8 or 17
  • Maven 3.6+
  • PostgreSQL (optional for local dev if using H2 profile)

Run the Application

mvn clean package
java -jar target/report-detect-backend-1.0.0.jar

Run Tests

mvn test -Dtest=SecurityRBACVerificationTest

Security Configuration

Default accounts created on initialization:

  • admin / 123456 (ADMIN)
  • auditor / 123456 (AUDITOR)
  • user / 123456 (USER)
