Abstract

The application belongs to the technical field of intelligent automobiles, and particularly relates to a driver monitoring system test evaluation method based on a video injection test platform.S1, driver driving state data acquisition;S2, video injection test platform construction;S3, deployment and operation verification of the measured DMS system;S4, DMS system test and evaluation; based on a high-fidelity video injection test platform, real driving videos are injected into the measured DMS system deployed in the ECU, which significantly overcomes the limitations of high cost, high risk and difficult scene reproduction of traditional real vehicle testing. The single precision and recall rate of various dangerous behaviors and complex face shielding states can be accurately calculated, and the massive data can be converted into a standardized system-level comprehensive performance score, which greatly improves the objectivity and traceability of the evaluation, provides clear guidance for subsequent perception network structure optimization and alarm threshold dynamic adjustment, and thus shortens the development and verification period of the DMS system.
