AI Technical Summary

Technical Problem

Existing digital twin scenario reconstruction systems for traffic accidents lack verifiable data traceability mechanisms, making it difficult to confirm the authenticity and integrity of the data, and they cannot be operated and verified offline independently in third-party judicial appraisal institutions.

Method used

A standardized encapsulation process with embedded verifiability is constructed. Through multimodal data tracing, hash digest, logical consistency verification and OpenX standard mapping, a deep-binding signature file is generated and packaged into an independently executable sandbox program to achieve self-verification of data integrity and independent operation.

Benefits of technology

It achieves end-to-end evidence solidification from multimodal data to digital archives, supports offline independent operation on general computing terminals, lowers the technical review threshold for judicial appraisal, and provides a highly credible electronic evidence generation solution.

Abstract

This invention discloses a self-verifying encapsulation and preservation method and system for digital twin scenarios of traffic accidents. The method includes: acquiring multimodal data and calculating fingerprints and hash digests to construct a data traceability chain; mapping 3D point clouds and dynamic trajectories to the OpenX standard to generate a standardized scene encapsulation; calculating uncertainty intervals and logical check codes based on error covariance and physical laws; integrating fingerprints, digests, intervals, check codes, and the traceability chain into a meta-data package and binding it to the scene encapsulation with a signature; integrating the bound data and verification program into an independent executable sandbox program; automatically verifying integrity during runtime, reproducing the accident trajectory, and exporting a digital archive. This invention achieves end-to-end verifiability and offline verification of accident scenarios, providing a highly credible evidence carrier for determining liability.
